DESCRIPTION
[0001] The entire contents of Priority Request DE 20 2013 006920.1 is incorporated into this application by way of reference.
[0002] The present invention relates to a tool device, which is suitable to be used with a machine tool and, in particular, with a hand-operated machine tool having a drive device that moves around a geometric drive axis.
[0003] The invention will be described below mainly with the use of the example of a tool device that is suitable for use with a machine tool and, in particular, for use with a hand-operated machine tool having a drive device which rotates around a geometric drive axis. This limitation of the illustration is not intended to limit the possible uses of such a tooling device.
[0004] Instead of the term "tool device", later in this document the term "tool" will also be used in a simpler way. But this should not be interpreted as a limitation either.
[0005] A machine tool is a device that has one or more drive motors and possibly one or more transmission devices. The tool device drive device is the component or components, respectively, through which torque is applied to the tool device, generally a drive shaft/output shaft, a drive shaft/an output shaft. output or similar.
[0006] A hand-operated machine tool comprises a support device, especially handles and the like, through which the machine tool can be operated by an operator with the tool attached to it. Typically, hand operated machine tools are equipped with an electric drive motor, but there are also other known types such as hydraulically powered machine tools, or pneumatically powered machine tools or muscle power driven machine tools.
[0007] In the prior art, a variety of tools is known, which are intended to be used with a machine tool having a circumferential drive device. Such tools are, for example, drills, sanding discs, cutting discs, circular saws and so on. These tools are attached to the output device which - depending on the application, the tool and the machine - rotates at a speed between close to 0 to several 1000 revolutions per minute and, in extreme cases, also at a significantly higher speed. During operation, the tool is brought into contact with a workpiece by a more or less high pressure, where it then carries out the corresponding machining operation. Machining forces that occur in the distance from the pivot, for example cutting forces or sanding forces, result in a torque around the drive rod that is compensated by the torque transmitted from the machine tool to the tool device. The transmission of the actuating moment to the tool is made through the tool clamping device through which the tool is fixed to the actuating device. Therefore, for a tool which, during machining, always rotates essentially in the same direction, the forces acting on the clamping device essentially occur in the same direction, but differ in height.
[0008] In the prior art, machine tools having a rotating oscillating tool receiving device are also known. An oscillating unit of the tool device is, in the present context, to be understood as an oscillating unit without a hub, as it is known from a bow saw device in particular. An arch saw device is in the present context to be understood in particular as a nose saw device, a saber saw device or a plaster-wall saw device or the like. A machine tool having an oscillating drive device is in the present context to be understood as a machine tool with a movement of the tool drive device when the tool drive device starts to move from a position center in a first rotating direction and which is locked to a stop and then the direction of rotation is reversed again until the movement is stopped.
[0009] The angular distance from the center position to its end position can typically be up to 5 degrees. However, for implanted machines, usually angles less than 1 degree to 2.5 degrees are common, which corresponds to a total angular movement (from 1st end position to 2nd) of 2 degrees to 5 degrees. This oscillatory movement is typically performed from 5,000 to 50,000 times per minute. However, there are lower and higher oscillation frequencies (in the present context, expressed as oscillations per minute).
[00010] Reversing the direction of rotation causes the tool machining forces to also change their direction, whereby, as is known, the machining forces always act against the direction of movement or, in the present context, against the direction of rotation , respectively. The machining forces that change its direction result in a torque corresponding to the lever arm, which is the distance from the tool processing point to the rotating geometric axis, in which the torque reverses the direction through oscillation. The torque resulting from the machining forces is superimposed with another moment, which is effective both during machining and when idle, namely, from the moment of inertia of the tool torque to the deceleration of the tool after its highest speed (by example, each maximum amplitude of the sine curve for a sinusoidal rotary speed variation of the tool drive device) and the tool re-acceleration in the opposite direction, which occurs after the rotation reversal.
[00011] The torques arising from the machining forces and the kinematic factors of the oscillating unit are applied by the machine tool and introduced through the drive device in the tool device.
[00012] The present invention aims to design the tool device in such a way that the torque, which was introduced through the drive device, can be reliably absorbed.
[00013] This objective is achieved by the subject of the present invention.
[00014] Preferred embodiments of the present invention are the subject of embodiments.
[00015] According to the present invention, the tool device comprises a clamping device through which the tool device can be fastened to the machine tool in such a way that its drive shaft and a geometric axis of rotation of the tool are substantially coincident. The terms "drive spindle" and "tool rotation geometric axis" denote the machine tool rotation axis and the tool device geometric axis of rotation, respectively.
[00016] Furthermore, at least two drive area regions are provided, which are separate from that geometric axis of tool rotation, each having a plurality of surface points. The term "drive area region" (later in this document, sometimes referred to as "drive area") refers to an area that remains directly or indirectly, at least partially, in contact with the machine's output device. tool to accommodate torque from the machine tool. The term "surface point" in the present context means points on the upper side of the drive area region, and is to be understood geometrically.
[00017] The term is used to distinguish the geometric point where a tangent plane is contiguous against the area. The vector on the surface perpendicular to the tangent point describes the orientation of the surface at that point in space, which is defined by, for example, a three-dimensional coordinate system or other work planes or work surfaces.
[00018] A surface has an infinite number of surface points due to the fact that each point on the surface is also a surface point in the present sense. However, to describe a unidirectional curved surface or a multidirectional curved surface for practice, it is sufficient to have a finite number of surface points. The term unidirectionally curved is to be understood as a cylindrical surface that is curved at each point in only one direction, for example a cylindrical surface. The term multidirectionally curved is to be understood as a surface that is curved at least at one point in different directions, for example a spherical surface.
[00019] A smooth surface has only one tangent plane that coincides with the surface itself. Therefore, to distinguish a smooth surface, a single surface point is sufficient and can be any point on the smooth surface.
[00020] Since the surface points are geometric points, they are not visible on the surface.
[00021] For planes tangential to these surface points, special geometric conditions apply. Tangential planes, as usual in geometry, are planes that are formed perpendicular to the normal vectors of the surface points and that are in contact with the surface at the surface point. The term "normal vector" means a vector that is oriented at that surface point exactly perpendicular to the surface.
[00022] The tangential planes at these surface points are tilted in two directions. On the one hand, the tangential planes are tilted against an axial plane, which includes the output rod. Additionally, these tangential planes are inclined relative to a radial plane, which extends perpendicular to the output shaft.
[00023] Thus, the arrangement of this drive area region differs, compared to known prior art tool devices for oscillating machines.
[00024] For known tool devices, as shown, for example, in the German Patent Application No. DE 10 2011 005 818 A1 and the German Utility Model Application No. DE 296 05 728 U1, the tools in the connection region for the machine tool drive devices are of a substantially flat design. This means that they extend in this area on a plane that is perpendicular to the geometric axis of rotation of the tool.
[00025] By now it should have been noted that, in a preferred mode, the drive area region is substantially smooth, which means that the normal vectors of all surface points are aligned parallel to each other and thus the The trigger area region has only a single tangent plane as a whole. However, within the scope of the present invention, it is also possible for the drive area regions to be curved in a unidirectional manner or a bidirectional manner. In this case, the normal vectors are no longer parallel to each other.
[00026] The invention is based on the following considerations:
[00027] The region of the tool in which the torque is applied is subjected to an alternating bending stress due to the oscillating movement. This is particularly problematic for the metallic materials from which the tools in question in the present context are usually produced. Metals have a crystalline structure. If local overloads arise in a region of a metal component, it means that the stresses acting on the component at that point are higher than the stresses that can be tolerated by the component, then microcracks can occur between the individual grains of the metal microstructure. metal. These microcracks affect component strength in two respects. On the one hand, in the region where microcracks were incurred, no voltage is transmitted to the component. This means that stresses within this region can be increased by crack formation, which decreases the effective area for force transmission.
[00028] On the other hand, a phenomenon arises which is commonly called the "notch effect" in mechanical engineering. The name comes from the fact that, in the region of a braid, especially when the notch has sharp edges, a local stress concentration occurs, which, in the region of the surrounding notch material, leads to shear stresses that are higher than the shear stresses in the component regions that are not affected by such geometry.
[00029] These increased stresses cause the crack formation to progress, and this eventually leads to component failure.
[00030] This process, which, for example, is documented in the works of Palmgren and Miner, is called damage accumulation.
[00031] The properties of a material or a component to tolerate balance loads and, in particular, alternating bending stresses, are usually represented by the so-called SN curve of this component. The SN curve is based on the finding that an alternating load, for the Wohler fatigue test is called load changes, in particular for a component comprising steel, can be tolerated, in many cases, on a permanent basis if the component may incur between 2 million and 6 million (depending on the material) of such load changes in that load without damage. In mechanical engineering, one speaks, then, of the so-called fatigue resistance of the material or component.
[00032] A driven oscillating tool scales as indicated above, for example with a frequency of 20,000 oscillations per minute. That's 20,000 charge cycles per minute in the diction of fixed component design of operation or 1.2 million cycles per hour.
[00033] The stress test lower fatigue limit of 2 million load cycles is thus exceeded after 2 hours of machine tool or tool operation.
[00034] Due to the inventive design, the torque load is increased so that it can be tolerated by the tool device. This is primarily achieved in the sense that the drive areas are arranged at a distance from the geometric axis of rotation. Since the force to be accommodated by the tool is determined as the ratio between torque and distance, it follows that Fr = M/r (M measured as a torque in Nm (Newtonmeter), F as a force at point r in N and r is the distance from the point of force application away from the geometric axis of rotation of the tool in m).
[00035] Zooming the point of force application outwards, ie away from the geometric axis of tool rotation, reduces the torque.
[00036] The slope of the drive areas additionally results in the point of force application being increased as a whole, whereby the local load is reduced, and, for proper design, the introduction of force into the remaining regions of the tool is improved.
[00037] A portion of the tool devices, which is commonly used in oscillating machines, have an operating region that is disposed in the circumferential direction, such as saw tools and cutting tools. The tool operating region thus extends substantially in a plane perpendicular to the geometric axis of rotation of the tool.
[00038] For such tools, it is common in the prior art that the clamping region is also constructed flat. The actuation moment is then initiated as a force in a direction perpendicular to the tool plane, eg by pins, a actuating star or the like. In the tool plane, the tool is especially rigid so that the input of force is carried out only over a relatively small region. In this region, this can then lead to higher local stresses, which leads to a reduction in tool operational stability.
[00039] According to the present invention, the force transmission is performed for such a tool first from the inclined area, whereby - for a respective construction - the force transmission area is increased and, thereby, the local charge is reduced.
[00040] It should be noted at this point that it is essential to reduce peak loads. Due to wear or even destruction of the tool, stress concentrations that lead to microcracks are generated and, additionally, promoted, only through the above described. A reduction in peak voltage concentrations can achieve a significant extension of tool life.
[00041] According to a preferred embodiment, there is at least one drive area region, for which at no surface point, the normal vector at that surface point passes in a straight line extending through the geometric axis of rotation of the tool. Therefore, such drive area region is not at any surface point oriented towards the geometric axis of rotation of the tool, but the region of drive area is "twisted" with respect to the geometric axis of rotation of the tool. In this way, the machine tool driving forces are not introduced tangentially into this region of the drive area at any point on the surface, so that torque transmission is further improved.
[00042] As explained above, the drive areas are preferably designed substantially smooth. This means that the trigger areas have a plane region with essentially the same tangent plane, which can be bounded by edges, single curved surfaces, or multiple curved surfaces, and so on. Respectively, through curved edges or areas, they can pass along other regions of the tool device.
[00043] The advantage of flat drive areas is that, through them, a tool device can be provided, which, on the one hand, can either be fixed without play on the machine tool drive device - if it is designed accordingly, and for which, when appropriate tolerances and material properties, such as elasticity and so on, are provided, a contact area between the machine tool drive device and the tool device is possible, through the which region of power transmission is increased.
[00044] According to an additional preferred embodiment, the drive areas are curved, at least in sections. The curvature can be designed either unidirectionally as well as bidirectionally, convex or concave, with a fixed radius of curvature or a variable radius of curvature.
[00045] Curved areas can also be designed so that, through their shape and the elasticity of the material, they are subjected to an elasticity through which the curvature changes and, in particular, through which the curvature essentially disappears of a certain load. This means that a substantially flat drive area is provided.
[00046] In a preferred embodiment, the tool device comprises in the region of the fixture device at least a first upper boundary plane and at least a second lower boundary plane. In that case, these boundary planes are arranged substantially perpendicular to said geometric axis of rotation of the tool. Even preferably, these two boundary planes are far apart. Preferably, each of these drive area regions is disposed between one of these first upper boundary planes and one of these second lower boundary planes, preferably in such a way that the drive area region is in contact with the respective boundary plane , but that doesn't cut the same. In particular, by arranging at least one drive area region between these boundary planes, a very large drive area region can be reached and the voltage in this drive area region is correspondingly low. Preferably, a first group of actuation area regions, except for at least one actuation area region, is disposed between one of said first upper boundary planes and one of said second lower boundary levels, and more preferably a second group of drive area regions is arranged between a first additional upper boundary plane and a second additional lower boundary plane. In particular, by grouping several of the drive range regions and by assigning the boundary planes, both a simple production of the tooling device is possible and a particularly homogeneous input of torque into the tooling device can be achieved.
[00047] In a preferred embodiment, a plurality of drive area regions extend between a single upper boundary first plane and a single lower boundary second plane. Most preferably, all such drive area regions extend between a single first upper boundary plane and a second single lower boundary plane. In particular, by extending these drive area regions between a first upper boundary plane and a second lower boundary plane, a torque transmission area with low space requirement can be achieved and, in addition, a material use required lower can be achieved. It is also advantageous, in particular, for this type of design of the drive area regions, to achieve that the torque is transmitted in a particularly uniform and thus smooth way to the material to the tooling device.
[00048] In a preferred embodiment, at least a first boundary plane and a second boundary plane are provided, which are spaced apart by a distance T. Preferably, the tool device comprises, in particular, in the region of the device of fastening, substantially a wall thickness t. Still preferably, the distance T is selected in relation to the wall thickness t from a defined range. It has proved advantageous to define the distance T and the wall thickness t in a relationship. In particular, therefore, favorable stiffness ratios in the clamping region of the tool device can be achieved and thus a favorable torque input from the machine tool to the tool device can be achieved. Preferably, the distance T is selected from a range, where T is preferably greater than one times t, preferably, t is greater than twice t, more preferably, it is greater than three times t, even preferably, the distance T is less than 20 times t, preferably less than 10 times t, more preferably less than 5 times t. In particular, if the wall thickness t is in a range between 0.75 and 3 mm, preferably if it is in a range between 1 and 1.5 mm, the distance T is particularly preferably essentially 3.5 times t. For the present case, this is essentially +/- 0.75 times t. In particular, by means of this relationship between the distance T and the wall thickness t, stiffness ratios in the range of the clamping device of the tooling device can be achieved, whereby the introduction of particularly favorable torque into the tooling device can be achieved and thus a long service life of the tool device can be achieved.
[00049] In a preferred embodiment, the torque transmission region comprises a plurality of drive area regions. Preferably, said plurality of drive area regions are symmetrically rotatable arranged around the geometric axis of rotation of the tool.
[00050] "Symmetrically rotating around the geometric axis of rotation of the tool", in the sense of the present application, shall mean that the plurality of drive area regions merges - geometrically observed - into itself through the rotation around the geometric axis of tool rotation by at least one angle that is greater than 0 degrees and less than 360 degrees - or any angle as well. In particular, one of these angles is 360 degrees/n, where n is a natural number greater than 1.
[00051] In particular, through a symmetrically rotating arrangement of the drive surface regions, it is possible to reduce the additional stresses in the tool device and uniformly stress the drive area regions, respectively, and thus in particular, achieve an increased service life. Still preferably, for a rotationally symmetrical alignment of the drive area regions, the tool device can be accommodated in different angular positions with respect to the geometric axis of rotation of the tool. Preferably, the tool device can be moved in distinct angular steps around the geometric axis of rotation of the tool and can be accommodated in the machine tool.
[00052] In a preferred embodiment, at least two of these drive area regions are arranged symmetrically to a symmetry plane. Preferably more than two such actuation area regions are arranged symmetrically to the plane of symmetry, preferably four. In the present context, in particular, the geometric axis of rotation of the tool is in the plane of symmetry. Even preferably, these drive area regions are disposed substantially contiguously. A contiguity arrangement within the meaning of the invention can in particular be understood as an arrangement in which the drive area regions are connected by a transition region. Preferably, such a transition region can be formed by a curved area region or an at least partially smooth extension area region. More preferably, such a transition region is tangentially contiguous with at least one, preferably both of these drive area regions. In particular, through a symmetrical and also contiguous arrangement of the drive area regions, a particularly high stability of the drive area regions can be achieved and therefore a good transmission of force to the tool device can be achieved.
[00053] In a preferred embodiment, the fixture has a sidewall. Preferably, said side wall extends radially away from the geometric axis of rotation of the tool. More preferably, this sidewall extends between the first upper boundary plane and the second lower boundary plane. Preferably, this sidewall comprises the drive area regions. In particular, the design of the clamping region with a sidewall results in a substantially hollow conical indentation in the region of the clamping region, but this hollow conical indentation does not have a circular cross-section, but a cross-section with a variable spacing from the sidewall to the geometric axis of tool rotation in a direction orthogonal to geometric axis of tool rotation. In particular, through the described type of mode of clamping region, a particularly stable clamping region and thus a good introduction of torque into the tool device can be achieved.
[00054] In a preferred embodiment, the sidewall has substantially an average wall thickness t1. Preferably, the average wall thickness substantially corresponds to the wall thickness t. In the present context, this wall thickness t1 and t, respectively, is preferably selected from a defined range, wherein said wall thickness is preferably greater than or equal to 0.2 mm, preferably is greater than 0 .5 mm and more preferably is greater than 0.8 mm. Even preferably, the wall thickness is less than or equal to 4 mm, preferably it is less than 2 mm and most preferably it is less than 1.5 mm. More preferably, the wall thickness t is substantially 1mm or 1.5mm or, preferably, is also a dimension between 1mm and 1.5mm. In particular, by choosing a suitable wall thickness in the aforementioned range, it is possible to obtain, on the one hand, a tool that has a light and thus a low moment of inertia and, on the other hand, a tool that is sufficiently stable .
[00055] In a preferred embodiment, this sidewall extends essentially radially closed around the geometric axis of rotation of the tool. In another embodiment, the sidewall has recesses or breaks in its extension around the geometric axis of rotation of the tool. In particular, through a closed circumferential sidewall, a particularly stable attachment region can be achieved; by a broken sidewall or by a sidewall which has recesses, a fixture can be achieved which has particularly light and low moment of inertia.
[00056] In a preferred embodiment, the fixture has a cover surface section. Preferably, this cover surface section attaches directly or indirectly to at least one of these drive area regions. In this case, the indirect connection of the cover surface section with one of the actuation area regions is to be understood, in particular, in the sense that the surface section and the actuation area region are connected by a connection region a the other. In that case, such connecting portion is preferably to be understood as a curved wall or as a, at least in sections, wall of straight extension. Preferably, the direct connection of the cover surface section with at least one of these drive area regions is to be understood in the sense that this cover surface section is separated from the drive area region only by an intermediate section related to production , or the measure that joins directly to it. Such production-related intermediate section is to be understood, in particular, as a bending radius, an inclined shape or the like. Preferably, the extent of that surface-covering section has at least one area component perpendicular to the geometric axis of rotation of the tool. Still preferably, the surface-covering section extends at least in sections substantially perpendicular to the geometric axis of rotation of the tool. Preferably, through this configuration of the covering surface section, further stabilization of the actuation area regions can be achieved.
[00057] In a preferred embodiment, the cover surface section is substantially disposed in the region of one of these first upper boundary planes. Preferably, the securing device has a particularly small radial extent in the region where the covering surface section is disposed. Even preferably, the roof surface section is substantially in the region of the first upper boundary planes, even preferably, it is disposed between one of these first upper boundary planes and the lower boundary planes. In particular, the arrangement of the covering surface section in the region of the first upper boundary plane is easily made, and can, in particular, lead to a further stabilization of the fixing device.
[00058] In a preferred embodiment, the covering surface section extends in the radial direction from radially outward towards the geometric axis of rotation of the tool. Still preferably, the cover surface section has at least one recess. More preferably, this cover surface section has several, preferably a plurality of recesses. In particular, through these recesses, the rotating inertia of the tool device can be reduced and thus its tension can be reduced.
[00059] In a preferred embodiment, at least one of these recesses is substantially disposed in the region of the geometric axis of rotation of the tool. Even preferably, a plurality of such recesses are disposed substantially in the range of that geometric axis of rotation of the tool. Substantially in the range of that geometric axis of rotation of the tool it should be understood as, in particular, that one of these recesses includes the geometric axis of rotation of the tool, or that at least one of these recesses immediately joins the geometric axis of rotation of the tool, or which is only a short distance away from it. In particular, through one or more recesses in the region of the geometric axis of rotation of the tool, a simple clamping of this tool device in a machine tool can be achieved and thus a good transmission of force from the machine tool for the tool device can be achieved.
[00060] In a preferred embodiment, one or several of these recesses are arranged symmetrically rotating around the geometric axis of rotation of the tool. Still preferably, all these recesses are arranged symmetrically in a rotary manner around the geometric axis of rotation of the tool. In particular, through this type of alignment of the recesses, an imbalance with the movement of said tooling device can be avoided or reduced, so that an improved tooling device can be achieved.
[00061] In the preferred mode, one of the normal vectors in one of these tangential planes is oriented in the radial direction towards the output rod. Preferably, the normal vectors of several of these, preferably, of all these tangential planes in the radial direction are oriented away from the geometric axis of rotation of the tool. In particular, through this orientation of the tangential planes, the clamping device provides the shank as compared to a conventional shaft hub connection. This configuration of the clamping region provides, in particular, the possibility of simple production and the driving forces of the machine tool which are transmitted and can be particularly uniform in the tool device.
[00062] In a preferred mode, one of the normal vectors in one of these tangential planes is oriented in the radial direction to the geometric axis of rotation of the tool. Preferably, the normal vectors of several of, preferably, all tangential planes are oriented in the radial direction to the geometric axis of rotation of the tool. In particular, through this tangent orientation, the clamping device provides the hub portion in comparison to a conventional shaft hub connection. In such a configuration of the clamping region, the driving forces are transmitted by the inner surface (hub portion), such surfaces are particularly well protected against dust and damage.
[00063] In a preferred embodiment, the tool device comprises at least one operating region, at least one clamping region and at least one connecting region. Preferably, the operating region is configured to act on a workpiece arrangement or a workpiece. A workpiece or a workpiece arrangement is to be understood, in particular, as a semi-finished product, a machine element, a component, an arrangement of several such elements, a machine, preferably a component of a motor vehicle, a building material, a construction or the like. An operating region is preferably to be understood as a cutting device, a sanding device, a cutting device, a scraping device, a lever device or the like. Still preferably, a connection region is to be understood as a section of said tool device, through which the actuating forces are transmitted from the clamping region to the operating region, in which in clamping region the actuating forces are input from the machine tool into the tooling device. Still preferably, the connecting portion is a smooth section, a curved section, a corrugated section or a bent section. Still preferably, this connection region is integrally formed with at least this operating region, or at least with this clamping device. Preferably, this connection region can be produced from the same or a different material as that of the operating region or the clamping device, and can be connected thereto. Preferably, such a connection is a form-fit connection, a force-fit connection, or a material-engagement connection, or preferably a combination of several of these types of connection. Particularly preferably, it is welded, riveted, caulked or bolted. Even preferably, a unique connection region is disposed between the clamping device and each such operating region. In particular, with the described configuration of the tool device, the clamping device, the operating region and the connecting region, an advantageous transmission of the actuating forces from the connecting device to the operating region can be achieved.
[00064] In a preferred embodiment, at least one of these connection regions is arranged in a certain region of the fixture. Preferably, at least one of these connection regions is disposed substantially within the region of one of the second lower boundary planes, which is further away from a receiving machine tool than the second lower boundary planes. Preferably, it is arranged in the region of one of the first upper boundary planes and, more preferably, it is arranged between these boundary planes. More preferably, at least one of these connection regions substantially coincides with these second lower boundary planes. Still preferably, all connecting regions are arranged in the manner described above. Even preferably, the covering surface section, and preferably one of, most preferably all of the connecting regions are disposed diametrically opposite the connecting device. That is, the covering surface section is arranged in the region of the first upper boundary plane/at least one of, or preferably all, connecting regions are arranged in the area of the second boundary plane or vice versa. In particular, through the type of construction and arrangement of the connection regions described, a particularly stable tooling device can be achieved and thus an even input of torque into the tooling device can be achieved.
[00065] In a preferred embodiment, the angle α is included between one of these tangential planes and this radial plane, wherein said radial plane is perpendicular to the output shaft. Preferably, angle α is selected from a certain range, where angle α is preferably less than 90 degrees, in particular it is less than 80 degrees, and more preferably is less than 75 degrees. Even preferably, the angle α is greater than 0 degrees, in particular, it is greater than 45 degrees, and more preferably, it is greater than 60 degrees. More preferably, angle α is in a range between 62.5 degrees and 72.5 degrees. Preferably, angle α is selected in the range mentioned above due to the component properties (in particular, geometry, wall thickness, modulus of elasticity, strength and the like) of the torque transmission region and/or the torque device. tool and/or is preferred due to the forces that occur. In particular, through the above-described selection of the angle α outside said range, a stable torque transmission region can be achieved, and on the other hand, also a uniform introduction of the driving forces into the tool device. It is usually preferable to choose angle α less than 70 degrees, as the risk of obstruction is then lower. In the present context, the term "obstruction" is to be interpreted in such a way that the tool device cannot be removed from the machine tool as programmed, which means in particular without an additional force. Similar effects to this "obstruction" are known in mechanics especially as self-locking. As an advantage, an angle α, which was selected from said range (α > 70 degrees), results in a particularly low space requirement. As an additional advantage, the tendency of the tool device to clog can be reduced in this torque transmission region by a smaller angle α (α < 70 degrees). As a particularly preferred range for angle α, the range of 60 degrees (+/- 5 degrees) has shown that in this way a relatively small installation space can be achieved and that an accidental obstruction of the tool device can be reduced or avoided.
[00066] In a preferred embodiment, the angle β is included between one of these tangential planes and this axial plane, where the output rod is located in this axial plane. Preferably, angle β is selected from a certain range, where angle β is preferably less than 90 degrees, in particular it is less than 70 degrees and more preferably is less than 65 degrees. Furthermore, preferably, the angle β is greater than 0 degrees, preferably, it is greater than 15 degrees, and most preferably, it is greater than 30 degrees. More preferably, angle β is substantially 30 degrees, 45 degrees or 60 degrees. More preferably, the angle β deviates only slightly from one of the three aforementioned values of the angle, where preferably slightly below a range should be understood as preferably +/- 7.5 degrees, in particular +/- 5 degrees, and more preferably +/- 2.5 degrees. In particular, through the described selection of the angle β outside of said range, a particularly stable torque transmission region can be achieved and thus a uniform torque input from the machine tool to the tool device can be achieved. The transmissible torque increases, in particular, with a decrease in the angle β. Preferably, for configurations desiring high transmittable torque, angle β is selected from a range of 0 degrees < β < 30 degrees. In particular, space requirements decrease with increasing angle β. Preferably, for configurations that want a small space requirement, angle β is selected from a range of 60 degrees < β < 90 degrees. In a particularly preferred embodiment, where a large torque is particularly transmissible and a low space requirement is desired, the angle β is essentially 60 degrees.
[00067] In a preferred embodiment, the tooling device has an even number of drive area regions. Preferably, the tooling device has 4 or more drive area regions, in particular it has 8 or more drive area regions, and more preferably it has 16 or more drive area regions. Even preferably, the tooling device has 64 or fewer drive area regions, in particular it has 48 or fewer drive area regions, and more preferably has 32 or less drive area regions. Furthermore, preferably, the tooling device has an odd number of drive area regions and preferably has an even number of drive area regions. Preferably, the number of drive area regions is a function of the size of the tool device. Even preferably, a tooling device may also have a greater number of drive area regions than specified in the present context. In the present context, a large tool device is to be understood, in particular, as a tool device, which essentially has a diameter exceeding 50 mm or more. Even preferably, the tool device has a diameter of substantially 30 mm. In particular, through the number of drive area regions, the machine tool driving forces can be transmitted in pairs in the tool device. It has been found that a particularly durable and thus improved tooling device can be achieved, in particular, by such introduction in pairs of the driving forces in the tooling device.
[00068] In a preferred embodiment, the drive area regions are substantially arranged in a star-like manner. Preferably, the drive area regions are substantially star-like disposed around the geometric axis of rotation of the tool. Still preferably, through the drive area regions, a three-dimensional body is described, which is cut by a plane orthogonal to the geometric axis of rotation of the tool and has essentially the base area of a star-shaped polygon.
[00069] In the sense of the present invention, the term polygon should not only be understood to be the mathematically exact shape that has vertices at obtuse angles or vertices at acute angles, but it should also be understood as a shape in which the vertices are rounded.
[00070] More preferably, the star-like arranged drive area regions appear similar to a toothed rod of a conventional shaft hub connection, in that the rod has a basic conical shape due to the double slope of the drive area regions . In particular, through the star-shaped arrangement of the drive area regions it is possible to arrange a plurality of drive area regions in a small space and transmit a large drive force from the machine tool safely to the tool device .
[00071] A series of tool devices, according to the invention, comprises at least two of said tool devices. In that case, such a tool device has, in particular, a reference plane. The reference plane is perpendicular to the geometric axis of rotation of the tool. The reference plane has at least one reference diameter or other reference dimension from the trigger area regions. In that case, a first distance Δ from a first surface of the covering surface section to the reference plane for tool devices other than a series lies between a first lower limit and a second upper limit.
[00072] In the sense of the invention, a reference plane is to be understood as a plane whose position is determined in the axial direction of the geometric axis of rotation of the tool, which contains the same reference diameter for a first tool and at least one tool this series. In this case, the axial position of this reference plane in the axial direction may be different from at least a first and a second tool in this series, due to the double slope of the drive area regions. Using the reference plane, the axial position of the reference diameter for a tool device is particularly defined. This leads in particular in the axial direction to a fixed reference point for several tool devices of a common series. Figuratively speaking, this approach can be particularly understood that an imaginary ring (reference diameter, reference dimension) is threaded in the axial direction in the drive area region, and this defines a particular axial position, which may differ for different tool devices . In particular, by specifying a lower limit and an upper limit, it is possible to take into account the unavoidable tolerances in the fabrication of the tool device. Preferably, these limits were selected from a range of a few tenths or a few hundredths of a mm.
[00073] In a preferred embodiment of this series, the distance Δ for at least two different tool devices of this series is substantially constant. Preferably, constant is to be understood in the sense that the distance Δ of a first tooling device and the at least one second tooling device or the several second tooling devices is at least within this limit. In particular, the fact that the distance Δ moves within a series of tools in a narrow tolerance band, it is possible that the tool devices of a series are positioned substantially equal in the axial direction and thus a safe introduction of the torque can be ensured.
[00074] In a preferred embodiment of a series of at least two tool devices, at least two tool devices in the series have different average wall thickness t or ti. In particular, by means of tool devices with different wall thicknesses, it is possible to make the tool device suitable for the load; since on tools, which are intended for different uses, for example sawing or sanding, different forces act, and these different forces can be taken into account, in particular, by the different wall thicknesses.
[00075] In a preferred embodiment, a series comprises at least two tool devices, which have a switching region, which is arranged substantially equal with regard to its position in relation to the geometric axis of rotation of the tool and the areas of drive. Even preferably, each tool device comprises such a switching region, and preferably each such tool device is distinguished by at least one application parameter, such as, in particular, a preferential drive energy. Still preferably, such application parameter can take into account the type of tool, the type of manufacturer or other machine tool parameters or, preferably, it can take into account the energy required to drive the tool device. Preferably, the switching region comprises at least one switching device. Preferably, this switching device is characteristic for at least one of these application parameters. In particular, through the described configuration of the switching region, it is possible to maintain different tools of a series for various application areas; and thus to oppose overloading the tool devices from the start.
[00076] In a preferred embodiment of a series of at least two tool devices, at least a first tool device comprises a first switching device. Preferably, this first switching device is intended to cooperate with a first switching element, which is preferably arranged in a machine tool. Still preferably, at least one second tooling device in the series comprises a second switching device. Even preferably, the second switching device is provided to cooperate with a second switching element. Preferably, a first switching element is arranged in a first machine tool and, more preferably, the second switching element is arranged in a second machine tool. Preferably, the switching devices and the switching elements are designed in such a way that the first switching element can cooperate with the first switching device and the second switching device. Preferably, the second switching element is designed in such a way that it does not cooperate with the first switching device, but cooperates with the second switching device. In particular, through this configuration of the switching devices, it is possible to restrict certain tools to specific machine tools. In that case, on the one hand, it can be achieved that, in particular, a tool device that has a clamping region that is provided for small driving forces, will not be received in a machine tool that provides driving forces that can damage that clamping region of the tool device. On the other hand, it can be achieved that the tool device which requires high driving forces or has a high torque cannot be received on a machine tool which is not fitted for this purpose. Thus, damage to the machine tool can be avoided.
[00077] In a preferred embodiment of the series of at least two tool devices, the shape of a basic area of at least one of, preferably of all switching devices is selected from a group of shapes. Preferably, this group has at least one of the following elements: - a polygon with a plurality of vertices, preferably 3, 4, 5, 6, 7, 8 or more vertices, - a circle, - an ellipse, - an arc with a variable radius or a constant radius or - a combination of several of the ways mentioned.
[00078] In particular, through the design of this switching device, it can be adapted to the respective requirements on the tool device and thus an improved series of tool devices can be achieved.
[00079] In a preferred embodiment, a series of at least two tool devices comprises at least two tool devices, each of which has switching devices, wherein the switching devices have the same geometric shape but different sizes . Preferably, all tool devices comprise a switching device that has the same geometric shape, but at least partially different sizes.
[00080] In a preferred embodiment, a series of at least two tool devices comprises at least one tool device, wherein the switching device is designed as a projecting portion compared to a switching reference plane. Preferably, a keying reference plane is understood as a plane perpendicular to the geometric axis of rotation of the tool. Still preferably, the switching reference plane is disposed substantially in the region of the covering surface section, or it coincides with the covering surface section. Even preferably, the array comprises a second tool arrangement with a second protruding keying region. Preferably, at least a first span of a switching device is greater than the respective span of the second switching device. Preferably, the first tooling device for the machine tools is provided with a high driving energy, and even preferably, the second tooling device for the machine tools is provided with a low driving energy. In this case, a high drive energy of the first machine tool must be understood in the sense that this drive energy is greater than the drive energy of the second machine tool. Preferably, the first similar extension on the first tool device is greater than the same extension of the switching device on the second tool device. Therefore, high-performance tools can be reserved, in particular, for machines that are intended for professional use in industry and craft companies (professional machines); and tooling devices can be reserved for lower performance requirements, both on professional machines as well as on DIY (stand-alone) machines that are intended for use in the private sector. This makes it possible, in particular, to adapt the tool devices to the respective drive energy, thus and improved tool devices can be achieved.
[00081] In a preferred embodiment of a series of at least two tool devices, at least one of the switching devices is constructed as a recess. Preferably, all switching devices in the series are constructed as recesses. Even preferably, the switching devices are arranged in the region of a switching reference plane. Preferably, at least one span of one switching device is greater than the respective span of the other switching device. In particular, a tooling device that is intended for a professional machine with a high drive energy has a small switching device. A second tooling device of the same series, which is provided in particular for a DIY machine, has opposite the first switching device a large switching device. For this, it applies, in particular, that a professional machine has a higher drive energy compared to a DIY machine. The dedicated DIY machine tool device thus fits both the professional machine as well as the DIY machine, while the professional tool cannot be mounted on a DIY machine. This prevents DIY machines from being damaged by tooling devices that are intended for the highest rated powers. In particular, the fact that the switching device (recess) for the professional machine is smaller than the switching device for the DIY machine, particularly stable tool devices can be achieved for a large drive energy.
[00082] In a preferred embodiment, a series of at least two tool devices comprises switching regions that are arranged in the region of this covering surface section. Particularly, if this covering surface section is arranged in the region of an upper boundary plane, the switching regions can be accessed particularly easily and therefore an improved tooling device can be achieved.
[00083] A method for manufacturing a tool device according to the invention comprises, for the fabrication of at least one drive area region, a primary modeling process step, or a reshaping process step or a reshaping step. generating process. Preferably, the process for manufacturing the at least one drive area region comprises a combination of several of the aforementioned process steps. The process steps for manufacturing at least one drive area region are selected from a group of process steps comprising at least the following manufacturing method:
[00084] forging, pressing, laminating, extrusion, bending, deep stamping, framing, flanging, smoothing, bending, stretching, pressing, sintering, casting, coating layer by layer or the like.
[00085] Preferably, a method for manufacturing a tool contour of the tool device has a separation process step. Preferably it is a thermal separation process step, preferably a mechanical separation process step or a combination of several such process steps. Still preferably, the tool manufacturing process steps are selected from a group comprising at least the following process steps:
[00086] sawing, sanding, milling, drilling, shearing, particle beam cutting, electron beam cutting, laser cutting, plasma cutting, flame cutting and cutting by EDM.
[00087] Preferably, the tool device, but at least the external form, is generated completely or predominantly by a generative manufacturing method.
[00088] In particular, through the above-mentioned manufacturing method, it is possible to produce a particularly precise drive area region and thus ensure a uniform introduction of driving forces into the tool device.
[00089] The following figures show various features and embodiments of the invention and are partially in a schematic form, in which a combination of individual features and embodiments in addition to the figures is also possible.
[00090] In a preferred embodiment, the tool device is received in such a way that, on the output axis of the machine tool, a small distance θ is obtained between an end face of the output axis and an opposite surface of the tool device. tool, when the tool device is received in the machine tool. Preferably, this distance is substantially equal at at least two points, which is symmetrically with respect to the geometric axis of rotation of the tool, preferably at several points. Preferably, a small distance in this context should be understood as a distance θ, which is in a range that is preferably less than 5 mm, preferably less than 2.5 mm, and more preferably less than 1.5 mm and, even more preferably, less than 0.8 mm, and more preferably, greater than 0.0 mm, preferably, greater than 0.25 mm, and most preferably, greater than 0.5 mm. Through a small distance θ, it can advantageously be achieved that the tool device, in particular in the event of an overload, is supported on the output shaft, and that a tilting of the tool device is avoided or reduced. Even preferably, it can be achieved that on insertion into the machine tool, the tool device can be received in an inaccurate manner not particularly significant.
[00091] In a preferred embodiment, the tool device comprises stepped drive area regions, wherein the stepped drive area regions can be understood, mutatis mutandis, as drive area regions or tool drive area regions , and their explanations can be transferred to the staggered drive area regions. Preferably, staggered is to be understood in the context of the invention in the sense that these actuation area regions are displaced against the side wall of the tool device. In contrast to the non-recessed drive area regions, the drive area regions are preferably not disposed on or on the side wall of the tool device, but preferably displaced towards it, preferably radially displaced, spaced particularly radially therefrom. .
[00092] A connecting device according to the invention is adapted to connect a tool device to a machine tool and, in particular, to the hand-operated machine tool. Preferably, a drive device of the machine tool drives the drive shaft, in particular, in an oscillating manner in a rotary manner. The connection device comprises a first connection region and a second connection region. The first connecting region is adapted to connect the connecting device to the machine tool, wherein the connecting device can be connected to the machine tool in such a way that the drive axis and a connection axis of rotation substantially coincide . The second connecting region is adapted to connect the connecting device to the tooling device. In the present context, at least one of the connecting regions has a clamping device, wherein the clamping device comprises at least two actuation area regions.
[00093] Furthermore, at least two drive area regions are provided, which are separate from the connection axis of rotation, and which each have a plurality of surface points. The term "drive area" means an area that can at least partially be directly or indirectly in contact with the machine tool output device to receive torque from the machine tool. The term "surface point" means points on the surface of the actuating surfaces in the sense as defined.
[00094] For planes tangential to surface points, special geometric conditions apply. Tangential planes are, as shown in common geometry practice, layers that are formed perpendicular to the normal vectors of surface points and that are in contact with the surface at the surface point. The term "normal vector" means a vector that is oriented at that surface point exactly perpendicular to the surface.
[00095] Tangential planes at surface points are tilted in two directions. On the one hand, the tangential planes are inclined relative to an axial plane, which includes the geometric axis of rotation of the tool. Additionally, the tangential planes are inclined relative to a radial plane that extends perpendicular to the geometric axis of rotation of the tool.
[00096] The clamping device of the connecting device and thus the actuating areas or the actuating area region of the connecting device preferably correspond, therefore, mutatis mutandis, to the actuating area region of the tool device.
[00097] In a preferred embodiment, the connection device comprises a first connection region that is arranged symmetrically rotating to the geometric connection axis of rotation. Preferably, the geometric axis of rotation connection is to be understood in the direction of the tool device as the geometric axis of rotation of the tool. Preferably, the connecting device is received with its clamping device on the machine tool in such a way that the connecting device can be actuated around the connecting axis of rotation, preferably in an oscillating or a rotary manner. Still preferably, the geometric connection axis of rotation and a first support axis coincide, and they are arranged parallel to each other or obliquely to each other. By such arrangement of the connecting region, a connecting device which has especially small imbalances can be achieved.
[00098] In a preferred embodiment, the second connection region is arranged symmetrically rotating to the geometric connection axis of rotation. By such an arrangement, the connection region can be arranged, in particular in a small size, in a region of low voltage.
[00099] In a preferred embodiment, the second connection region is arranged symmetrically rotating to the geometric connection axis of rotation. By such an arrangement, the tool device can be received in the connecting device in such a way that the geometric axis of rotation of that tool means and the geometric axis of rotation connection are substantially coincident with each other and thus small imbalances arise.
[000100] In a preferred embodiment, the connecting device comprises a first support device. Preferably, said first support device is adapted to cooperate with at least the first connection region and the machine tool. Preferably, the support device comprises a screw device, more preferably a hook device, a snap-on device or, more preferably, an engaging device.
[000101] In particular, by means of a support device with a screw device, a particularly simple reception of the connecting device in the machine tool can be achieved.
[000102] In a preferred embodiment, the connecting device comprises at least one second support device. Preferably, the second support device is adapted to cooperate with the second connection region and the tool device. Preferably, the tooling device is received in the connecting device in a material-fitting manner, preferably in a form-fitting manner, and particularly preferably in a force-engaging manner or in a combination of the types listed. Preferably, the second support device comprises a screw device, more preferably a hook device or a locking hook device, and particularly preferably a catch device.
[000103] In a preferred embodiment, the first support device comprises a first support axis. In this case, the first support axis is to be understood in the sense of the invention as the geometric axis along which the direction of action of a support force extends, and which can be applied by this support device. Preferably, for a screw device, the symmetry line of the same is to be understood as the geometric support axis. Additionally, the second support device comprises a second support axis, preferably the second support axis, mutatis mutandis, corresponds to the first support axis. Preferably, this first support axis and this second support axis are substantially parallel, in particular congruent to each other. Preferably, the connection axis of rotation coincides with the first support axis. In the sense of the invention, congruent can be interpreted as coaxial. By such arrangement of the support device, it can be particularly achieved that the connecting device on the machine tool and the tool device on the connecting device can be received particularly easily, especially in a single operation.
[000104] In a preferred embodiment, the first support device comprises a first support axis and the second support device comprises a second support axis. Preferably, the first support axis and the second support axis are arranged irregularly, particularly inexactly with each other. In the sense of the invention, irregular can be understood in the sense that the two support axes are not parallel to each other on the one hand, and that they do not intersect in space. Through such an arrangement, a particularly voltage-tolerant design of the connecting device can be achieved.

[000130] Figure 25 shows two cross-sectional views of additional embodiments of the connection device with a torque transmission by form fit (Figure 25a, a hollow body; Figure 25b, a solid body).
[000131] Figure 1 shows two views (Figure 1a, front view; Figure 1b, plan view) of a tool device 1. This tool device has two drive area regions 2. In the present context, an area region of drive 2 has several surface points 3. A tangent plane 4 can be assigned to each of these surface points 3 in the drive area regions 2. These tangential planes 4 are inclined with respect to a radial plane 6 and with respect to an axial plane 7. In the present context, the radial plane 6 is disposed orthogonally to a geometric axis of rotation of the tool 5 and an axial plane 7 surrounds the geometric axis of rotation of the tool 5a. Tool device 1 is provided for a rotary mode oscillating drive of a hand operated tool device (not shown). If the tool device 1 is driven by a suitable machine tool, then the tool device 1 is placed in an oscillating rotary motion around the geometric axis of rotation of the tool 5. Through the double inclination of the drive area region 2, slack-free support of the tool device 1 on the machine tool can be achieved. This is particularly advantageous for a sawing operation and a sanding operation or the like, since, in the present context, variable loads act on the tool device 1 with respect to the geometric axis of rotation of the tool 5, and a lost motion connection between the machine tool and tool device 1 may result in the connection being broken and thus, in particular, may result in damage to tool device 1.
[000132] Figure 2 shows a view of the tool device 1, in which it can be seen that the drive area region 2 extends between each of the upper boundary planes 8a and the lower boundary planes 8b. These boundary planes 8 are preferably arranged orthogonally to the geometric axis of rotation of the tool 5. In this case, in each case, the drive area region 2 extends from the upper boundary plane 8a to the lower boundary plane 8b or vice versa. -versa. Preferably, in the present context, the lower boundary plane 8b is located at the level of an operating region 13. In the present context, an operating region is to be understood as an example like a saw tooth, like a saw blade or the like . Thereby, the lower boundary planes 8b are disposed substantially at the level of the operating region 13, a particularly poor transmission of deformation of the operating forces of the operating region regions 2 in the operating region 13 is possible. Through different boundary planes 8 and thus through extensions of the actuation area regions 2, a particularly good adaptability to the requirements of the tool device is provided, in particular with regard to space requirements, clearance and transmission of torque. In the present case, the lower boundary planes 8b coincide with a common lower boundary plane 8b. The upper limit planes 8a do not coincide in this mode, which results in regions of actuation area 2 of different heights.
[000133] Figure 3 shows a view of the tool device 1, in which all the drive area regions 2 are delimited by a single lower boundary plane 8b and a single upper boundary plane 8a. These boundary planes 8 are arranged perpendicular to the geometric axis of rotation of the tool (fictional, geometric) 5. The lower boundary planes 8b are disposed substantially at the level of the operating region 13. In the direction of the geometric axis of rotation of the tool 5, the upper boundary plane 8a is spaced from the lower boundary plane 8b. If all the drive area regions 2 extend between a single upper boundary plane 8a and a single lower boundary plane 8b, then a particularly simple fabrication of the tool device is possible, and in addition a particularly uniform transfer of forces to starting from the machine tool (not shown) in tool device 1 is possible.
[000134] Figure 4 shows a part of the tool device 1 in a sectional view. The tool device comprises a geometric axis of rotation of the tool (fictional, geometric) 5. The tool device 1 can be driven oscillatingly revolving around the geometric axis of rotation of the tool 5. The region of driving area 2 is disposed away from the geometric axis of rotation of the tool 5, and extends in the direction of the geometric axis of rotation of the tool 5 between the lower boundary plane 8b and the upper boundary plane 8a. The upper boundary plane 8a and the lower boundary plane 8b are separated by the distance T. In the present context, the distance T depends on the wall thickness t, which also has the drive area region 2. Through this dependence, a relationship particularly favorable between the rigidity of the drive area regions and their sizes is achieved.
[000135] Figure 5 shows different sectional views (Figure 5a, top view; Figure 5b, front view) of the tool device 1. The tool device 1 has the geometric axis of rotation of the tool 5. The area regions of drive 2 are arranged symmetrically to a plane of symmetry 9. In the present context, plane of symmetry 9 includes the geometric axis of rotation of the tool 5. The regions of drive area 2 are arranged contiguously and lie in a region of transition 17. This transition region 17 is designed in dependence on the manufacturing process or the stress in transmitting force to tool device 1 and may have a radius. The drive area regions 2 extend between the lower boundary plane 8b and the upper boundary plane 8a, and they are spaced apart from the geometric axis of rotation of the tool 5. A symmetrical and, in particular, contiguous arrangement of the regions of drive area 2 allows the design of a highly stable tool device 1, as the drive area 2 regions can support each other.
[000136] Figure 6 shows several partial views (Figure 6a, top view; Figure 6b, front view) of the tool device 1. The tool device 1 has a geometric axis of rotation of the tool 5, and a plurality of regions of actuation area 2, wherein these actuation area regions extend between the upper boundary plane 8a and the lower boundary plane 8b. The drive area regions 2 are each disposed contiguous to each other and form a radially closed sidewall which is circumferential around the geometric axis of rotation of the tool 5. The drive area regions 2 are, each inclined with respect to the radial plane 6 and with respect to the associated axial planes 7. By means of such closed circumferential sidewall, on the one hand, a particularly stable tool device can be achieved and, on the other hand, a transmission of particularly uniform drive force from the machine tool (not shown) on tool device 1 can be achieved.
[000137] Figure 7 shows a detail of the tool device 1 in a sectional view. The tool device 1 has the geometric axis of rotation of the tool 5, the region of driving area 2 and a section of coverage area 10. The tool device 1 can be driven around the geometric axis of rotation of the tool of a Swivel oscillating way. Figure 7 shows that the actuation area region 2 is inclined relative to the radial plane 6. The actuation area region 2 extends between the upper boundary plane 8a and the lower boundary plane 8b. The actuation area region 2 abuts substantially immediately the coverage area section 10 in the region of the upper boundary plane 8a. By means of a thus arranged coverage area section 10, a further stabilization of the actuation area regions 2 can be achieved, and for the same size of the actuation area regions 2, large actuation forces can be transmitted as without the coverage area section 10.
[000138] Figure 8 shows several partial views (Figure 8a, plan view; Figure 8b, front view) of the tool device 1. This tool device 1 has the geometric axis of rotation of the tool (fictional, geometric) 5, a the plurality of drive area regions 2 and the coverage area section 10. The operating region 13 of the tool device 1 is intended to act on a workpiece or a workpiece arrangement (not shown). In each case, two drive area regions 2 are positioned adjacent to one another and are connected to a pair of additional drive area regions 2 by means of a connection region 11. The drive area regions 2 are arranged with rotational symmetry and they extend in the direction of the geometric axis of rotation of the tool 5 between the upper limit plane 8a and the lower limit plane 8b. The actuation area regions 2 are inclined with respect to the radial plane 6 and with respect to the assigned axial planes 7. Through the connection regions 11, the actuation area regions 2 form the closed side wall, which is circumferential around the geometric axis of rotation of the tool 5. By means of the illustrated symmetrically rotating arrangement of the drive area regions 2, the tool device 1 can be moved on the machine tool (not shown), provided with an appropriate design thereof, so that the tool device can machine a workpiece or a workpiece arrangement (not shown), which is still difficult to access.
[000139] Figure 9 shows a detail of the tool device 1 in a sectional view. The tool device 1 has the geometric axis of rotation of the tool 5 and the drive area region 2. This drive area region 2 has several surface points 3. For each of these surface points 3, a tangent plane 4 can be assigned. The radial plane 6 is arranged orthogonal to the geometric axis of rotation of the tool 5. The radial plane 6 includes an acute angle α with the tangent plane 4. Through this angle α and thus through the inclination of the tangent plane 4 against the radial plane. 6, it is particularly easy to receive the tool device 1 without play in the machine tool, especially when the tool device 1 is held in the machine tool (not shown) with a gripping force 18 in the direction of the geometric axis of rotation of the tool .
[000140] Figure 10 shows a detail of the tool device 1 in plan view, in which the geometric axis of rotation of the tool 5 can be observed merely as a point. The axial plane 7 includes the geometric axis of rotation of the tool 5 and can be seen as a straight line in Figure 10. For the surface point 3 of the drive area region 2, a tangent plane 4 can be assigned. The drive area regions 2 are positioned adjacent to one another and are spaced radially from the geometric axis of rotation of the tool 5. The tangent plane 4 includes an acute angle β with the axial plane 7. Through angle β together with the angle α, it is possible that the tool device 1 is centered with respect to the machine tool (not shown) when it is received in the machine tool.
[000141] Figure 11 shows multiple views (Figure 11a, cross-sectional view; Figure 11b, top view) of the tool device 1. The tool device 1 has the geometric axis of rotation of the tool 5 and a plurality of regions of drive area 2, which are arranged radially spaced from it. The drive area regions 2 are substantially flat. Additionally, these regions of drive area 2 are contiguously disposed, forming a closed sidewall, which is circumferential around the geometric axis of rotation of the tool. The drive area regions 2 extend in the direction of the geometric axis of rotation of the tool 5 between the upper boundary plane 8a and the lower boundary plane 8b. In the region of the upper boundary plane 8a, the coverage area section 10 is disposed. The coverage area section 10 preferably has a switching device 16. The switching device 16 is preferably arranged as a circular recess in the geometric axis of rotation of the tool. This circular recess has a first switching diameter Kd_1. Other tool devices (not shown) of the same series, which however are provided for other rated units, may have additional switching diameters (Kd_2, and so on) that are different from Kd_1. Kd_1 indicates, for example, a tool device 1 for professional use, Kd_2 (not shown) indicates a tool device for standalone use (DIY). Additionally, a lower section of the coverage area section 10a has a distance Δ to the reference plane 14. The position of the reference plane 14 is defined such that it contains a reference diameter 15 (nominal outside diameter, nominal intermediate diameter , nominal inside diameter or similar). For tool device different from a series, in particular at different wall thicknesses t, or also, due to unavoidable tolerances in the tool device fabrication, resulted in different positions based on the position in the direction of the geometric axis of rotation of the tool 5 , for nominally the same reference diameter 15. Starting from that position of the reference plane 14 in the direction of the geometric axis of rotation of the tool 5, the tool device comprises a substantially constant distance Δ from the lower covering area section 10a to that reference plane 14. Thus, wherein a plurality of tool devices of a series have a substantially constant distance Δ between the lower coverage area section 10a and the reference plane 14, a particular simple and secure accommodation is provided for the different tool devices 1 on the machine tool (not shown).
[000142] Figure 12 shows the same views of a tool device 1 as in Figure 11. However, in Figure 12 another tool device 1 of some series of tool device 1 is shown, different from the one shown in Figure 11. Therefore, below are mainly discussed the differences between the tool device 1, which is shown in Figure 11, and the tool device 1, which is shown in Figure 12. In the coverage area section 10 a switching device 16 is arranged as a recess in the geometric axis of rotation of tool 5. This switching device 16 includes a switching diameter Kd_2, although the switching diameter Kd_2 is smaller than the switching diameter Kd_1 (Figure 11). The switching device 16 is configured to cooperate with a second switching element (not shown), which is arranged on the machine tool (not shown). Through such design of the switching means 16 in a series of tool devices, it is possible to reserve specific tool devices 1 for certain machine tools and thus allow safe operation.
[000143] Figure 13 shows various illustrations of the different tool devices 1, particularly in relation to the switching device 16. Figure 13a shows a detail of a tool device 1 with a protruding switch device 16a. Figure 13b shows a tooling device 1 with a switching device 16b which is designed as a recess. For both switching devices 16a, 16b it is common that they are arranged in the region of the coverage area section 10 of the tool device 1. The tool device 1 comprises a plurality of drive area regions 2, which are arranged away from the geometric axis of rotation of tool 5.
[000144] Figure 14 shows different sections of a drive area 2 region of the tool device. Not shown is a flat drive area region, such a drive area region is also preferably possible. Figure 14a shows a unidirectionally curved section of drive area region 2. This section of drive area region 2 can be described by straight lines and curved grid lines bI. Curved grid lines bI have a constant radius of curvature RI. Such drive area region 2 corresponds, in sections, to a cylinder liner surface, and insofar as several different radii of curvature RI are provided, corresponds to a conical surface (not shown). In this case, the size of the radius of curvature RI is selected such that the actuation area region 2 changes in sections during transmission of the actuation forces to a plane or that it conforms to the cooperating opposite surface (not shown) with it to transmit the driving forces. Figure 14b shows a section of drive area region 2 with a bidirectional curvature. This section of drive area region 2 can be described by curved grid lines bI and curved grid lines bII. The bI grid lines have the constant radius of curvature RI and the bII grid lines have the constant radius of curvature RII. Such actuation area region 2 corresponds to, for the special case where the first radius of curvature RI and the second radius of curvature RII are of the same size, a spherical surface. In Figure 14b a drive area region 2 with different radii of curvature RI and RII is shown. In this case, the size of the radii of curvature RI and RII can be selected so that the actuation area region 2 changes at least partially during transmission of the actuating forces to a plane or that it conforms to the opposing surface (does not shown) that cooperate with it to transmit the driving forces. Figure 14c shows a section of a drive area region 2 with bidirectional curvature. This section of drive surface area 2 can be described by grid lines bI which have a constant radius of curvature RI and by grid lines bIa which have a variable radius of curvature RIa. In such drive area region 2, all grid lines can also have a variable radius of curvature (not shown). The size of the radii of curvature RIa and RII can be selected such that the drive area region 2 changes during transmission of drive forces in sections to a plane or that it conforms to the opposing surface (not shown) that cooperates with it to transmit the driving forces. In Figure 14, a concave curve drive area region 2 is shown, the expressed considerations can be transferred to a convex curve drive area region accordingly.
[000145] Figure 15 shows a tool device 1 that is accommodated in a machine tool 22. The tool device 1 comprises a clamping device 12, through which it is connected to the machine tool 22. tool 22 has an output shaft 22a which introduces the driving forces on tool device 1, in particular, its clamping device 12. Output shaft 22a moves around machine-tool geometry axis 22c, in particular , oscillatingly revolving, in this way too, the tool device 1 is brought into a similar motion. The tool device 1 has an operating region 13, which is adapted to act on a workpiece or a workpiece arrangement (not shown). The driving forces of the machine tool 22 are transmitted to the operating region 13 by the tool connecting region 11 of the clamping device 12. The machine tool 22 has an operating lever 22b, which is adapted to allow a change in the tool device 1.
[000146] Figure 16 and Figure 17 show a tool device 1 in different views. Figure 16 shows a plan view and Figure 17 shows a sectional view of the tool device 1. The fixture shown 12 of the tool device 1 is shown in Figures 16 and 17 as a star-shaped polygon with rounded apexes (connection regions 11). In the present context, the interrelationships discussed below can be applied at least, mutatis mutandis, to other forms of such a fastening device 12.
[000147] In the plan view, Figure 16, the rounded vertices (connection regions 11) of the polygon can be observed. A so-called polygon arm is formed by two of the drive area regions 2 and the connection region 11. The individual arms are offset by an equidistant angle k12 from each other. Preferably, the angle, preferably equidistant k12, results from the relationship: Full circle/(number of arms) = k12; for the present case 360 degrees/12 = 30 degrees. Preferably, through the equidistant angle k12, it is possible to accommodate the tool device 1 in different rotary positions on the machine tool. In the present case, the tool device (not shown) can be moved in distinct steps of 30 degrees relative to the machine tool.
[000148] The tool device 1 has in its coverage area section 10 a recess, preferably circular, with a diameter k10. Even preferably, for this recess, shapes other than the circular shape are also possible.
[000149] Preferably, this recess has a substantially circular shape and may additionally have recesses, preferably polygonal recesses or preferably groove-like recesses, extending from the circular recess, preferably extending radially outward. Preferably, through these recesses, a star-like polygon is obtained having, preferably, circular sections. Particularly advantageously, such recesses can be used for tool devices, which are particularly intended for high loads, especially on diving saw blades or the like.
[000150] Still preferably, the diameter k10 corresponds to one of the diameters kd_1 or kd_2 for the tool devices of a series of at least two tools. This recess in the coverage area section 10 is preferably adapted so that the tool devices 1 are held in the machine tool. Preferably, this recess is to be understood as a through recess/through hole of a support device (not shown), in particular of a screw device. The choice of diameter k10 can depend on various parameters, preferably the size of the support device (not shown) of the machine tool. This support device is particularly dimensioned in such a way that the tool device 1 is securely held in the machine tool.
[000151] The diameters k2 and k3 describe the external diameters of the fixation device. In a preferred embodiment, the outer diameter k2 is preferably selected from a range between 30 mm and 36 mm, preferably from 32 mm to 34 mm, particularly preferably the outer diameter k2 is substantially 33.35 mm (+/ - 0.1 mm).
[000152] In a preferred embodiment, the outer diameter k3 is preferably selected from a range between 22 mm and 27 mm, preferably from 24 mm to 26 mm, particularly preferably, the outer diameter k3 is substantially 25 mm (+/0.1 mm).
[000153] Distance k1 defines the distance of the two drive area 2 regions that are, in this view, parallel to each other (in a spatial view, the drive area 2 regions are slanted towards each other). Compared to a screw head (eg a hexagon or a square) the distance k1 corresponds to a key width.
[000154] In a preferred embodiment, this key width k1 is preferably selected from a range between 26 mm and 30 mm, preferably from a range between 27 mm and 29 mm, more preferably, the key length is substantially 28.4 mm (+/- 0.1 mm).
[000155] The diameter 15 indicates a reference diameter for the fixture 12 of the tool device 1. In a preferred embodiment, the reference diameter 15 is preferably selected from a range between 31 mm and 33 mm, preferably, from a range between 31.5 mm and 32.5 mm and, particularly preferably, the reference diameter 15 is substantially 32 mm (+/- 0.1 mm). In the present context, the reference diameter 15 is further preferably distinguished in the sense that the at least two different tool devices of a series of tools - observed in the direction of the geometric axis of rotation of the tool 5 - are at substantially the same level (+ /- 0.1 mm).
[000156] In the sectional view (Figure 17), in particular, the cross-sectional area of the fixture 12 is particularly well recognizable. In a preferred embodiment, the tool device 1 has, in the region of its fastening means 12, preferably a substantially constant wall thickness t1. More preferably, such wall thickness t1 is selected from a range between 0.75 mm and 1.75 mm, preferably it is selected from a range of 1 mm to 1.5 mm, and more preferably the thickness of wall t1 corresponds to substantially 1.25 mm (+/- 0.1 mm).
[000157] It has been found that an especially long service life for tooling device 1 can be achieved if certain transitions are rounded in clamping device 12 of tooling device 1 (preferably the radii: k6, k7, k8 and k9).
[000158] In a preferred embodiment, at least one of the radii k6, k7, k8 and k9, preferably different from them, more preferably all of them are oriented in the wall thickness t1. In the present context, preferably from a greater wall thickness t1 there is an enlargement of these radii, preferably at least of radii k7 and k9.
[000159] In a preferred embodiment (wall thickness t1 = 1.25 mm), the radius k6 is preferably selected from a range between 1 mm and 2.5 mm, preferably it is selected from a range between 1 .5 mm and 2.1 mm and, particularly preferably, radius k6 is substantially 1.8 mm (+/- 0.1 mm).
[000160] In a preferred mode (t1 = 1.25 mm), the radius k7 is selected from a range between 0.5 mm and 1.5 mm, preferably it is selected from a range between 0.8 mm and 1.2 mm and, particularly preferably, the radius k7 is substantially 1 mm (+/- 0.1 mm).
[000161] In a preferred mode (t1 = 1.25 mm), the radius k8 is selected from a range between 0.2 mm and 0.6 mm, preferably it is selected from a range between 0.3 mm and 1.5 mm, and particularly preferably the radius k8 is substantially 0.4 mm (+/- 0.05 mm).
[000162] In a preferred mode (t1 = 1.25 mm), the radius k9 is selected from a range between 2 mm and 3.5 mm, preferably it is selected from a range between 2.4 mm and 3 mm and, particularly preferably, radius k9 is substantially 2.7 mm (+/- 0.1 mm).
[000163] The drive area regions 2 are slanted in the illustration in Figure 17 by angle k13 with respect to an imaginary vertical line (parallel to the geometric axis of rotation of tool 5). In a preferred embodiment, this angle is selected from a range between 10 degrees and 30 degrees, preferably it is selected from a range between 17.5 degrees and 22.5 degrees, and more preferably angle k13 is substantially from 20 degrees (+/- 0.5 degrees).
[000164] Still preferably, the other dimensions of the tool device depend on the wall thickness t1, more preferably at least the radii k6, k7, k8 and k9, where a greater wall thickness t1 tends to lead to larger radii k6 , k7, k8 and k9, preferably at least to larger radii k9 and k6.
[000165] The diameter k2 preferably indicates the region of the drive area regions 2, from which they extend in a straight line. After this straight extension, the actuation area regions extend, preferably in radius k9 and then in coverage area section 10.
[000166] Preferably, the measure k5 and the radius k7 are interdependent. More preferably, measurement k5 is selected from a range between 0.1 mm and 1 mm, preferably, it is selected from a range between 0.3 mm and 0.7 mm, and particularly preferably, the measurement k5 is substantially 0.5 mm (+/- 0.1 mm).
[000167] The radius k6 is preferably facing the radius k7 and is greater than that. Also, radius k9 and radius k8 are preferably facing each other, more preferably radius k8 is smaller than radius k9.
[000168] In a preferred embodiment, the drive area regions 2 extend by one level (the direction is parallel to the geometric axis of rotation of the tool), at least for measure k14, substantially in a straight line. In the present context, a straight line according to the invention is to be understood in the sense that it has no significant curvature, preferably being in an unloaded condition, more preferably in a loaded condition. Preferably, measurement k14 is selected from a range between 1 mm and 3.5 mm, preferably, it is selected from a range between 1.5 mm and 2.5 mm, and particularly preferably, dimension k14 is substantially 2 mm (+/- 0.25 mm). Preferably, measurement k14 should be understood as the shortest linear course of the drive area regions 2.
[000169] The recess in the coverage area section, which is preferably adapted to cooperate with the support device (not shown) of the machine tool (not shown), has a diameter k10. The recess with diameter k10 is not necessarily a circular recess as shown in Figure 16 and Figure 17, but this recess may, regardless of the remaining appearance of tool device 1, also have a different shape (polygon or the like).
[000170] In a preferred embodiment, the fixation region 12 has a depth k11, more preferably, the depth k11 is selected from a range between 3.5 mm and 6 mm, preferably it is selected from a range between 4.5 mm and 5 mm, and particularly preferably the depth k11 is substantially 4.7 mm (+ 0.15 mm).
[000171] In a preferred embodiment, the fastening region 12 has a height k15, still preferably, the height k15 is selected from a range between 4.5 mm and 7.5 mm, preferably it is selected from a range between 5.5 mm and 6.5 mm, and more preferably height k15 is substantially 6 mm (+/- 0.2 mm).
[000172] Figure 18 shows a tool device 1, which by means of a screw device (fixing screw 9d, washer 9e, nut member 9f) is fixed to the output shaft 22a of the machine tool. The tool device 1 has an operating region 13 for acting on a workpiece or workpiece arrangement. From the tool drive area region 2, the driving forces are transmitted to the operating region 13. In this case, the tool device 1 is held by means of the tightening screw 9d, which exerts its force action through of washer 9e on tool device 1 of the machine tool. The transmission of the driving forces from the machine tool to the tool device 1 is achieved substantially by the form-fitting engagement of the drive area region 2 on the opposing surfaces on the output shaft 22a. The output shaft 22a is rotatably driven through the oscillating machine tool rotation axis 22c, and transmits this movement to the tool device 1 so that this movement pivotally oscillates around the rotation axis of tool 5. The tool device 1 is held in the machine tool in such a way that the geometric axis of rotation of the tool 5 and the geometric axis of the machine tool 22c are substantially coincident.
[000173] Figure 19 shows two versions of a tool device 1 that has the stepped drive area region 2a. These actuating surface portions 2a are arranged above the coverage area section 10 and preferably then non-rotatably connected thereto, preferably by a form-fit latch or a material interlock, and more preferably , welded, riveted, bolted or similar. In the present context, Figure 19a and Figure 19b each show a sectional illustration. Figures 19c and 19d each show a plan view from above of such a tooling device 1. The illustration of the tooling device 1 in Figure 19 is substantially based on, but not limited to, the illustration of Figure 18. Therefore, the differences between them are mainly addressed below.
[000174] In a tool device 1, as shown in Figures 19a and 19c, the angle α is substantially equal to 90 degrees. Thereby, this advantageously allows an easy fabrication of the tool device. In tooling device 1, as illustrated in Figures 19b and 19d, the angle α is substantially less than 90 degrees. Thereby, advantageously, a larger transmission area for torque transmission can be achieved.
[000175] Next, Figure 19 shows how the tool device 1 is fixed to the output shaft 22a of the machine tool, preferably by means of a screw device (fixture screw 9d, washer 9e, nut member 9f ). The tool device 1 has an operating region 13 for acting on a workpiece or workpiece arrangement. By means of the clamping device between the tool device 1 and the output shaft 22a, in the present context, preferably designed as a screw device (mounting screw 9d, washer 9e, female connection 9f), the tool device 1 is received in the machine tool and a force is exerted in the direction of the geometric axis of rotation of the tool 5.
[000176] If the tool device is received as programmed in the machine tool, a small distance θ is obtained between an output shaft 22a facing the surface of tool device 1 and a front surface 22d of the output shaft 22a. Preferably, the short distance should be understood as a distance θ that is in a range, preferably less than 5 mm, preferably less than 2.5 mm and more preferably less than 1.5 mm and most preferably less than 0.8 mm. Even preferably, this range is greater than 0.0mm, preferably it is greater than 0.25mm, and most preferably it is greater than 0.5mm.
[000177] From the stepped drive area regions 2a, the driving forces are transmitted to the operating region 13. In this case, the tool device 1 is held in the machine tool by means of the washer 9e, which exerts a force action by means of clamping screw 9d in tool device 1. The transmission of the driving forces of the machine tool in tool device 1 is achieved primarily by form engagement engagement (form engagement connection) in the region of stepped drive area 2a on opposite surfaces on output shaft 22a. The output shaft 22a is rotatably driven by the oscillating machine tool rotation axis 22c and transmits this movement to the tool device 1 so that it moves in a rotational oscillating manner around the tool rotation axis. 5. The tool device 1 is held in the machine tool in such a way that the geometric axis of rotation of the tool 5 and the geometric axis of the machine tool 22c are substantially coincident.
[000178] Figure 20 shows an additional variant of a tool device 1 with the staggered drive area regions 2a. The stepped drive area regions 2a are preferably substantially above, preferably directly above the operating region 13 in the direction of the output shaft 22a and, respectively preferably, they are disposed on a surface of the tool device 1 Still preferably, that surface of the tooling device is adapted to be opposite the end face 22d of the output shaft 22a when the tooling device is received by the machine tool. The actuation area regions 2a are preferably pivotally fixedly connected to tool device 1, preferably by a form-fit latch or a material-engage latch, more preferably welded, riveted, bolted or the like, or particularly preferred, configured integrals. Figure 20a shows a sectional view and Figure 20b shows a plan view from above of such tool device 1. It can be seen in the plan view (Figure 20b) that the stepped drive area regions 2a are distributed in a star-shaped way around the geometric axis of rotation of the tool. The illustration of tooling device 1 in Figure 20 is based on the illustration in Figure 18 and Figure 19, but should not be limited thereto. Therefore, the differences between them are mainly addressed below.
[000179] Next, Figure 20 shows how the tool device 1 is fixed to the output shaft 22a of the machine tool, preferably by means of a screw device (fixture screw 9d, washer 9e, nut member 9f ). The tool device 1 has an operating range 13 for acting on a workpiece or workpiece arrangement. By means of the clamping device, in the present context, preferably configured as a screw device (clamping screw 9d, washer 9e, female connection 9f) between tool device 1 and output shaft 22a, tool device 1 is received in the machine tool and a force is exerted in the direction of the geometric axis of rotation of the tool 5.
[000180] When the tooling device is received as programmed in the machine tool, a small distance θ is obtained between an output shank 22a facing the surface of the tooling device 1 and the end face 22d of the output shank 22a. Preferably, the small distance θ is in the range as proposed in the modality of Figure 19.
[000181] The support of the tool device as well as the transmission of driving forces in the tool device is carried out in the same way, as in the modality shown in Figure 19.
[000182] In an additional mode, at least one stepped drive area region 2a can be arranged below the upper surface section (Figure 19) and above the tool surface (Figure 20), which faces the machine tool in the area of the output shaft 22c, preferably, the stepped drive area region 2a is spaced both below the coverage area section and above the aforementioned tool surface range. This modality can be visually perceived as an intermediate variant compared to the modalities shown in Figure 19 and Figure 20. Still preferably, the stepped drive area region 2a can be formed integrally with at least a portion of the tool device 1 or, preferably, as a separate component, as shown in Figure 19 and Figure 20, be connected to the tool device 1. The stepped drive area region and the tool device are preferably cohesive, not positive or positive in such connection. , preferably welded, anchored, riveted, screwed or glued.
[000183] Figure 21 shows an embodiment of a tool device 1 that has protruding drive area regions 2b. Figure 21a shows a cross-sectional view of such a tool arrangement and Figure 21b shows the corresponding top view of the tool arrangement 1. These protruding drive area regions 2b may preferably have cylindrical portions as shown in Figure 21. Still preferably , can alternatively be made as truncated cones or, preferably, as sections with a cross-section in the shape of a polygon. The shape of the protruding drive area regions 2b is preferably independent of the rest of the tool device design.
[000184] These drive surface areas 2b are preferably disposed substantially above the operating region 13 in the direction of the output axis 22a, or on a surface of the tool device 1. More preferably, this surface of the tool device is adapted to be opposite the end face 22d of the output shaft 22a, if the tool device 1 is received in the machine tool. The drive area regions 2b are preferably pivotally connected to the tool device 1, preferably by form-fitting or by material-engaging, especially preferably welded, riveted, bolted or the like, or more preferably integrally configured. In this case (Figure 21b), a plan view can be seen in which the protruding drive area regions 2b are preferably distributed symmetrically in a rotary manner, more preferably at an equidistant distance or an integer multiple of an equidistant distance, around the geometric axis of tool rotation. The illustration of tooling device 1 in Figure 21 is primarily based on the illustrations in Figure 18 to Figure 20, but is not limited thereto.
[000185] Next, Figure 21 shows how the tool device 1 is fixed to the output shaft 22a of the machine tool, preferably by means of a screw device (fixing screw 9d, washer 9e, nut member 9f ). The tool device 1 has an operating region 13 for acting on a workpiece or workpiece arrangement. By means of the clamping device, in the present context, preferably as a screw device (clamping screw 9d, washer 9e, female connection 9f) configured between tool device 1 and output shaft 22a, tool device 1 is received in the machine tool and a force is exerted in the direction of the geometric axis of rotation of the tool 5.
[000186] When the tooling device is received as programmed in the machine tool, a small clearance δ is obtained between the output shaft 22a facing the surface of the tooling device 1 and the end face 22d of the output shaft 22a. Distance θ is preferably in the range as proposed in the modality in Figure 19.
[000187] The tool device support is realized in the same way as in the mode shown in Figure 19. In the mode (Figure 21) with protruding drive surface regions 2b, they engage with corresponding contact surfaces on the machine tool and the transmission of the driving forces in the tool device is carried out in a form-fitting manner.
[000188] Figure 22 shows a sectional view of a connecting device 1a for connecting a third tool device 1b to an output shaft 22a of the machine tool. The connecting device 1a is held on the output shaft 22a and thus on the machine tool by means of a first support device 30. The support device 30 preferably has a clamping screw 9d and a washer 9e, and a member of nut 9f is arranged on output shaft 22a. The connecting device 1a is received on the output shaft 22a in such a way that a small distance θ is obtained between an end face 22d of the output shaft 22a and a surface of the connecting device facing the tool device, preferably the surface opposite end face 22d. Through the small distance, secure reception of the connecting device 1a on the output shaft 22a can be achieved. In the connecting device 1a, a third tooling device 1b can be fixed by means of a second support device 31. The second support device 31 comprises a second support axis 31a, the first support device 30a having a first support device. support shaft 30a. The first support axis 30a substantially coincides with the connection axis of rotation. The first support axis 30a and the second support axis 31a are obliquely disposed to each other. The third tool device 1b has an operating region 13, which operating region 13 is adapted to act on a workpiece arrangement.
[000189] For a form-fitting torque transmission, the connecting device 1a comprises a clamping device with drive area regions 2. The drive area regions 2 are engaged to the output shaft 22a on opposing surfaces. Through this form-fitting engagement, the driving forces are securely transmitted from the output shaft 22a driven by the machine tool axis 22c in an oscillating and rotary manner to the connecting device 1a and thus to the second tool device.
[000190] The connecting device 1a is connected in a first connecting region 32a to the machine tool, and a supporting force acting on the connecting device 1a is preferably applied in the direction of the first supporting axis 30a, or respectively, a movement of the connecting device 1a in the direction of the first support axis is at least partially prevented. Additionally, the third tooling device 1b can be connected in a second connecting region 32b of the connecting device 1a. In that case, this connection may be a form-fit connection, preferably a material-engagement connection or, more preferably, a force-fit connection. Preferably, in the direction of the second support axis 31a, a support force is exerted on the tool device 1b or the connecting device 1a, respectively. Preferably, the second support device 31 comprises a screw device, more preferably, for applying the supporting force effect.
[000191] Figure 23 shows a sectional view of a connecting device 1a, which is similar to the connecting device shown in Figure 22. Therefore, below are mainly addressed the differences between these two connecting devices.
[000192] The third tool device 1b is held in the connecting device 1a by means of the second support device 31. The second support device 31 exerts in the direction of the second support axis 31a a support force effect of the third support device. tool 1b and preferably also on the connecting device 1a. The tool device 1 is connected via the second connecting portion 32b to the connecting means 1a. In that case, this connection may preferably be a form-fit connection, preferably a material-engagement connection or, more preferably, a force-fit connection. The second support axis 31a is oriented substantially parallel to the first support axis 30a, more preferably the first and second support axis are spaced apart from each other.
[000193] Figure 24 shows a cross-sectional view of a connecting device, which essentially corresponds to that of Figure 22 and also of the connecting device shown in Figure 23. The following will therefore stress the differences between these modalities.
[000194] The third tooling device 1b is held by means of the first support device 30 and the second connecting region 32b of the connecting device 1a. The first support device 30 exerts a supporting force in the direction of the first support axis 30a on the third tool device 1b and preferably also on the connecting device 1a. Such a connection may preferably be a form-fit connection, preferably a material-engagement connection, or more preferably a force-fit connection. Still preferably, said third tooling device and said connecting device comprise sections of protruding recesses, preferably these protruding sections are in connection with these recesses for a form-fit torque transmission from connection device 1a to the third tool device 1b.
[000195] Figure 25a shows a cross-sectional view of a connection device with torque transmission by form fitting from the connection device on the tool device. The connecting device is at least partially formed as a hollow body and thus it has, in particular, a low moment of inertia. Both the embodiment illustrated in Figure 25a and Figure 25b are similar to the previously described embodiments of the connecting device. Therefore, the differences between these two connection devices are mainly discussed below.
[000196] The tool device 1 is held on the machine tool output shaft 22a by means of a first support device 30, in particular a clamping screw 9d, a washer 9e and a nut member 9f. Torque transmission from the connecting device in the tool device 1 is at least partially achieved by means of the form-fitting elements 33rd. The form-fitting elements 33 can preferably be integrally formed with the connecting device or, preferably, as the components themselves inserted into or fixed to it.
[000197] The connecting device is received in the axial direction, that is, in the direction of the geometric axis of machine tool 22c in such a way that a small distance θ is obtained. Thereby, it can be achieved that the connecting device can be held in the machine tool, as the tool device is severely stressed, in particular, by bending moments perpendicular to the geometric axis of rotation of the tool. In particular, by means of this support, a tilting of the tool device can be neutralized in the connecting device and with it, the tool device can be received particularly securely in the machine tool.
[000198] The connecting device can preferably be composed of several parts, particularly preferably the base body is composed of two parts 34 and 35. In this way, it can be achieved that the connecting device has, on the one hand, a low weight (hollow body), and that, on the other hand, it consists of parts that are relatively simple to produce.
[000199] Still preferably, these various parts can be connected to one another at one or several connection points 36 in a material-fit manner. Through such a configuration of the connecting device, a particularly easy connecting device can be achieved, which in particular due to low inertial forces only induces a low voltage.
[000200] Next, the tool device 1 is accommodated on the output axis 22a by means of the connecting device in such a way that the geometric axis of rotation of the tool 5 and the geometric axis of machine tool 22c are substantially coincident. The connecting device is connected in a first connecting portion 32a to the output shaft 22a of the machine tool. Furthermore, the tool device 1 is connected in a second connecting region 32b to the connecting device. In this case, the actuating torque is transmitted to the connecting device (first connecting portion 32a) from the machine tool via the actuating area region 2 in matter of form-fitting.
[000201] The form fitting elements 33 (Figures 25a and 25b) are preferably spaced from the geometric axis of rotation of the tool 5. In addition, they are displaced around the geometric axis of rotation of the tool preferably by an equidistant angle or , preferably by an integer multiple of such an angle. Still preferably, the shape-locking elements 33 or a plurality of groups of the shape-locking elements are arranged with rotational symmetry about the geometric axis of rotation of the tool.
[000202] The tool device 1 has an operating region 13 which is adapted to act on a workpiece or workpiece arrangement (not shown).
[000203] Figure 25b shows a cross-sectional view of a connecting device with torque transmission by form fitting from the connecting device on tool device 1 (second connecting portion 32b). In the present context, the connecting device is, unlike the embodiment shown in Figure 25a, formed essentially as a solid body and has, in particular, a high shape stability, and is particularly easy to manufacture. The embodiment illustrated in Figure 25b essentially corresponds to the embodiment shown in Figure 25a. Therefore, the differences between these modalities will be mainly addressed below.
[000204] The tool device 1 is held on the machine tool output shaft 22a by means of a first support device 30, which has, in particular, a clamping screw 9d, a washer 9e and a nut member 9f . The transmission of torque from the connecting device to the tooling device 1 is at least partially achieved by means of the form-fitting elements 33.
[000205] The connecting device is received in the axial direction, i.e. in the direction of the geometric axis of machine tool 22c in such a way that a small distance θ is obtained, through which a particularly safe reception of the tool device in the machine -tool can be achieved.
[000206] The connecting device, in particular its base body, can preferably be integrally formed, preferably at least the base body of the connecting device is produced by a primary molding fabrication method or by a reshaping fabrication method as already described also for the fabrication of the tool device, preferably a forging, a sintering, generative fabrication processes and the like.
[000207] By means of the connecting device, the tool device 1 then is received on the output axis 22a, so that the tool axis of rotation and the machine tool axis substantially coincide. The connecting device is connected at a first connecting portion 32a to the output rod 22a. Additionally, the tool device 1 is connected in a second connecting region 32b to the connecting device. In this case, the drive torque is also transmitted from the machine tool to the connecting device through the drive area regions 2 in a form-fitting manner.
[000208] The tool device 1 has an operating region 13, which is adapted to act on a workpiece or workpiece arrangement (not shown).
