    A honing machine for internal honing and external honing is proposed, with which thin-walled tubes can be machined both inside and outside simultaneously or in succession. However, conventional parts such as piston rods can only be honed on the outside and long pipes can only be honed on the inside on this machine.
    If the pipes to be machined are to be honed on their inner and outer surfaces, simultaneous machining of the inner and outer surfaces is of great advantage. Such processing can be carried out with the honing machine according to the invention both in the vertical and in the horizontal.
    State of the art
    A horizontal honing machine for external honing of shafts is known from DE 2 856 623 C2. The shaft is clamped in a spindle unit with a rotary drive and a tailstock. The shaft rotates during machining. The tool moves in the longitudinal direction and advances the honing stones radially. The long stroke movement of the honing tool is also superimposed by a coaxially directed oscillation movement of the honing stones, so that the honing cut tracks become wavy. This is intended to increase the cutting performance significantly. This honing machine is designed exclusively for the external honing of piston rods and does not allow conversion to internal machining.
    The German utility model DE 8 814 248 U1 also describes an external machining of cylindrical bearing journals, in which, however, the entire kinematics (lifting, rotating and central feed movement) is carried out by the honing tool. The workpiece itself is at rest.
    In "Honing - Basics and Applications", Gerhard Flores, Vulkan-Verlag Essen 1992, ISBN 3-8027-2904-8 on page 119, an external honing process on a vertical honing machine is described. A conventional honing machine is shown, which can be honed both inside and outside. However, this is not possible at the same time; the second processing step can only take place after the conversion has taken place. The external honing tool is firmly installed on the machine table, the workpiece is mounted with a double joint. The honing stones can be fed hydraulically or mechanically.
    Object of the invention
    Based on the prior art, a honing machine is proposed on which an internal or external machining of a workpiece can be carried out both simultaneously and one after the other.
    This object is achieved according to the invention in a honing machine according to the preamble of claim 1 in that the spindle unit identifies a rotary drive and a lifting drive for a honing tool for internal honing of a workpiece, that an external honing device is provided, and that the external honing device is relative to the workpiece in is displaceable in the axial direction.
    In the honing machine according to the invention, the spindle unit only has to perform an oscillating movement in the direction of the longitudinal axis of the bore to be machined. The rotary movement required for honing is generated by a rotary drive of the clamping unit. The workpiece to be processed is clamped in the clamping unit. With this configuration of the honing machine, it is possible to carry out both internal and external honing on this honing machine.
    Due to the external honing device which is displaceable in the axial direction relative to the workpiece, it is possible to hone a workpiece on the outside without the external honing device executing a rotary movement. This is made possible by the fact that the honing machine according to the invention has a rotationally drivable clamping unit. External honing works with the rotation of the workpiece, driven by the spindle of the clamping unit. The rotary drive of the clamping unit can be used for internal honing as well as external honing.
    The external honing device is advantageously arranged on a carriage which performs an oscillating movement parallel to the longitudinal axis of the workpiece to be machined.
    The stroke and the feed movement are carried out by the tool. This slide can be moved in the axial direction of the workpiece, for example by a rack and pinion drive. Of course, other linear drives can also be used.
    Due to the inventive conception of the honing machine, it is possible that a workpiece is machined by internal honing and is simultaneously machined by external honing. At the same time, however, it is also possible to machine a workpiece either only by internal honing or only by external honing. The honing machine according to the invention therefore offers a flexibility not known from the prior art with regard to the machining methods and the workpieces to be machined.
    The flexibility of the honing machine according to the invention is increased even further by the fact that the rotary drive of the clamping unit can be locked. Conventional internal honing is then possible, in which the workpiece is firmly clamped and the honing tool also performs a rotary movement. For this it is necessary that the spindle unit has a rotary drive, this rotary drive advantageously being lockable. This locking can be advantageous if a workpiece is machined by external honing and internal honing at the same time.
    Then namely, the honing stones of the honing tool and the external honing device should be arranged opposite one another, so that the compressive forces occurring during honing are transmitted directly through the tubular workpiece from one honing stone to the other. As a result, there is no elastic deformation of the workpiece to be machined. This results in a higher machining performance while at the same time improving the quality of the workpiece to be machined.
    However, it can also be advantageous if the spindle unit, and with it the honing tool, executes a rotational movement in the opposite direction to the rotational clamping unit. In this way, increased material removal can be achieved on the inside of the pipe. However, this also makes the honing angle flatter.
    It is also advantageous if the spindle unit has a feed device for the honing tool.
    In addition, the hone is articulated and preferably gimbaled to a spindle of the spindle unit. This makes it possible for the honing stones of the honing tool to lie against the bore to be machined in the best possible way over their entire length. In a corresponding manner, it is advantageous if the external honing device is cardanically mounted on the slide. As a result, a similar effect is achieved, namely that the honing stones of the external honing device lie against the surface of the workpiece to be machined in the best possible way over their entire length.
    In a further advantageous embodiment, the external honing device can be coupled to the spindle unit in the axial direction in order to avoid speed deviations from the internal honing tool to the external honing tool. This means that the oscillating stroke movement of the honing tool and the external honing device take place synchronously. This results in the same honing angles for internal and external honing. It is also ensured that the honing stones of the honing tool and of the external honing device do not change their position relative to one another, at least in the axial direction, during the honing process.
    The length of the coupling can be adjusted so that even with honing tools of different lengths, the outer and inner honing stones can assume the same axial position and can support one another. In this case, the own axial drive of the external honing tool must be switched off or both axial drives must be controlled synchronously in a suitable manner by the control.
    If the honing stones are arranged opposite one another, elastic deformations of the workpiece are thereby effectively prevented during machining. In this way, particularly thin-walled pipes can be honed with a high removal rate and optimum precision at the same time. In particular when machining thin-walled tubes, it is therefore advantageous if the honing stones of the honing tool and the external honing device have the same position relative to the workpiece. In addition, it is desirable and advantageous if the honing stones of the honing tool and the honing stones of the external honing device have the same number and length.
    In some applications, in particular in external honing, it is advantageous if the clamping unit is designed as a tailstock.
    The above-mentioned object is also achieved by an external honing device with several honing stones, each honing stone being adjustable in the radial direction, in that an adjusting device for the honing stones comprises at least one linear drive for each honing stone and a common drive motor for all linear drives. This configuration of the external honing device according to the invention ensures that all linear drives are fed evenly.
    In addition, the construction costs and the mass are reduced, since only one drive motor is required. As a result, only one drive motor has to be controlled.
    The infeed device, which, together with the external honing device, performs an oscillating stroke movement during the honing process, is mechanically very robust and can also be well controlled in terms of control technology.
    A wide variety of designs are possible as linear drives. The linear drive can be designed as a rack and pinion drive or as a ball screw spindle.
    In order to prevent the honing stones from tilting, it is particularly advantageous if each honing stone is advanced in the radial direction via, for example, two racks. This ensures that the contact pressure between the honing stone and the workpiece is constant over the entire length of the honing stone, regardless of the wear and tear on the honing stone.
    In order to apply the necessary contact pressure, it is advantageous in many cases to connect a reduction gear, preferably an epicyclic gear, and / or an angular gear, upstream of the feed device. An eccentric epicyclic gearing is particularly advantageous because it reduces the feed movement of the drive motor into the smallest radial feed movements and, thanks to its self-locking, keeps the honing stones that have been fed in the radial position.
    This means that the drive motor can be de-energized as soon as the feed movement has been completed. A large reduction ratio of the gears reduces the torque to be applied by the common drive motor to carry out an infeed movement. As a result, the mass and the overall volume of the drive motor can be reduced. This is particularly advantageous since the drive motor takes part in the oscillating stroke movement of the external honing device.
    A particularly advantageous coupling of the common drive motor with the feed devices of the honing stones is a toothed belt. It goes without saying that the drive motor has a correspondingly shaped pinion and the feed devices also have pinions. The toothed belt can also serve as overload protection for the delivery devices.
    To compensate for any positional errors in the workpiece surface to be machined, the honing stones are gimbaled in a common frame. The workpiece is firmly clamped in the spindle of the clamping unit and can be stored at the free end in the center with a tip of a tailstock.
    Both diamond, cBN or conventional cutting materials such as silicon carbide or corundum can be used.
    In order to ensure a particularly advantageous cardanic suspension of the external honing device, it is provided that the external honing device has two spaced-apart structures that are firmly connected to one another, and that the honing stones, the linear drives and the reduction gears are arranged between the two structures. This results in a very light and nevertheless high-strength structure of the external audio device. The guidance of the honing stones between these structures is guaranteed and it is also possible to arrange a ring between these structures on which the structures are rotatably mounted. This first mounting between the ring and the structures is a first axis of rotation of the cardanic suspension according to the invention. Advantageously, the ring is again mounted rotatably on the carriage of the honing machine, the axes of rotation of the two mountings running orthogonally to one another. This ensures a very efficient and precise cardanic suspension of the external honing device.
    The cardanic suspension avoids tilting moments acting on the external honing device because the cardanic suspension - viewed in the axial direction - is arranged between the structures of the external honing device and the honing stones are also arranged there. This further increases the machining precision.

    Description of the exemplary embodiments
    In Fig. 1 a honing machine according to the invention for simultaneous external honing and internal honing is shown schematically. The honing machine 1 comprises a machine bed 3. A clamping unit 5 for the workpiece 7 to be machined, here a thin-walled tube, is placed on this machine bed 3. The clamping unit 5 cannot be moved in the axial direction, but is screwed to the machine bed 3. However, it can also be displaceable in the axial direction and is then moved in the axial direction via a linear drive (not shown in FIG. 1). It is then possible for the clamping unit 5 to carry out an oscillating movement in the axial direction during the honing process.
    The clamping unit 5 comprises a drive motor 9 which can drive a clamping means 11 in which the workpiece 7 is clamped. When the drive motor 9 is activated, the clamping means 11 rotates and with it the workpiece 7. Drive motor 9 and clamping means 11 form a rotary drive. However, it is also possible to lock the clamping means 11 so that the workpiece 7 cannot perform any rotary movement.
    At the other end of the machine bed 3, a spindle unit 13 is provided, which also has a drive motor 15. The drive motor 15 is used to set a spindle 17 of the spindle unit 13 in rotation as required. A honing tool 19 for internal honing is attached to the spindle 17. The honing tool 19 is cardanically connected to the spindle 17 in a manner known per se, so that the honing stones 21 of the honing tool 19 can lie against the inner wall of the workpiece 7 in the best possible way.
    The honing tool 19 comprises an infeed device which essentially comprises an infeed rod 23 and, connected to it, two infeed cones 25. When the infeed rod 23 is displaced in the axial direction relative to the hone 19, the infeed cones 25 bring about a radial infeed movement of the honing stones 21. The infeed rod 23 of the hone 19 is actuated via the spindle unit 13.
    The spindle unit 13 can be moved on the machine bed 3 in the axial direction, that is to say in the direction of the longitudinal axis of the workpiece 7. This makes it possible for the honing reamer 19 to execute an oscillating movement inside the workpiece 7 to be machined. The oscillating stroke movement of the spindle unit 13 is indicated by a double arrow 29 in FIG. 1.
    Likewise, the spindle unit 13 for the spindle drive can have a multi-stage, manually shifted mechanical gear for presetting the speed. The servo function of the drive motor is used to fine-tune the speed.
    An electromechanical delivery device (not shown) is integrated into the spindle unit 13 and carries out the delivery of the internal honing tool 19. The infeed device executes a controlled rotary movement which causes a relative rotation to the rotary movement of the spindle 17. This relative rotation is used to advance the internal honing tool 19.
    The spindle 17 can be locked in the spindle unit 13. This is advantageous when the workpiece 7 is to be machined simultaneously by external honing and internal honing.
    If the honing machine 1 according to the invention is to be used for honing, there are several options. The first option provides that the workpiece 7 is set in rotation via the clamping unit 5. Then the honing tool 19 usually only makes an oscillating movement and does not rotate.
    Alternatively, it is of course also possible that the clamping means 11 of the clamping unit 5 is locked and the honing tool 19 performs both a rotary movement and an oscillating stroke movement, as is standard in conventional internal honing.
    Of course, it is also possible that both the workpiece 7 and the honing tool 19 execute a rotary movement.
    According to the invention, an external honing device 31 is also provided, which is mounted on a slide 33. The carriage 33 can also be displaced in the axial direction of the workpiece 7 on the machine bed 3. The oscillating stroke movement of the slide 33 is indicated by a double arrow 29 in FIG. 1.
    The external honing device 31 comprises a plurality of honing stones 37 which rest on the outer surface of the workpiece 7. The honing stones 37 can be advanced radially inward. The infeed movements of the honing stones 21 and 37 are also indicated by arrows (without reference symbols).
    The (rotary) clamping unit 5 sets the clamped workpiece in rotation in such a way that the desired honing angle is set inside and outside of the workpiece 7 in cooperation with the oscillating stroke movements of the internal honing tool 19 and the external honing device 31.
    The spindle unit 13 receives the internal honing tool, hereinafter also referred to as the honing tool 19, in an articulated connection between the spindle 17 and the honing tool 19 so that the honing tool 19 with its honing stones 21 can align with the inner surface of the workpiece 7.
    It must be ensured that the lengths of the honing stones 21, 37 of the inner and outer honing tools are as equal as possible, so that with the same axial position of the tools, the workpiece 7 is completely supported on the outside and inside and thus no lateral shape deviation occurs can.
    If only finished honed surfaces inside and outside are required, then after the honing process and the removal of the internal and external honing tool, the clamping end, which is located in the (rotary) clamping unit 5, can be achieved by a machining unit with a turning tool (not shown) to be turned off. In this case, however, the workpiece 7 is to be picked up / caught by carrying straps (not shown) after the separation, so that the workpiece 7 does not fall down after the parting and is thereby damaged.
    When the workpiece 7 protrudes with the clamping end into the rotary clamping unit 5 (see FIG. 1), these clamping surfaces are to be prepared accordingly as steps from the pre-machining. The honing stones 37 can thus run over the edge of the bore.
    During internal and external honing with the honing machine according to the invention, it is particularly advantageous that internal and external machining take place at the same time and that even a thin-walled tube is carried out by e.g. Machining forces of an internal honing tool 19 is not deformed. The simultaneous application of the honing stones 21, 37 of both tools stabilizes the workpiece 7 in its starting position and the processing quality is independent of the wall thickness of the workpiece 7.
    In FIG. 1, an essential advantage of the inventive honing machine 1 becomes very clear: the honing stones 21 for internal honing arranged in the cutting plane and the honing stones 37 of the external honing device also arranged in the cutting plane lie directly opposite one another. The wall of the tubular workpiece 7 lies in between.
    This means that the feed forces of the honing stones 21 and 37 are supported by the respective opposing honing stone, so that an elastic deformation of the workpiece 7 does not take place. This not only enables the machining of very thin-walled workpieces 7, but at the same time allows a higher removal rate, which significantly increases the economic efficiency of machining with a honing machine 1 according to the invention.
    Of course, the honing tool 19 and the external honing device 31 not only have two honing stones 21 and 37, respectively. In many applications, four, six or more honing stones 21 and 37 are evenly distributed over the circumference, these honing stones 21 and 37 preferably being arranged directly opposite one another for the reasons mentioned above.
    Since both the external honing device 31 and the honing tool 19 perform an oscillating movement in the direction of the longitudinal axis of the workpiece 7, it must be ensured that the honing stones 21 and 37 are not only arranged opposite one another in the circumferential direction, but also during the machining of the workpiece 7 always assume the same axial position. This can either take place in that the control of the spindle unit 13 and the slide 33 run synchronously. Modern machine controls usually allow this. The spindle unit 13, the slide 33 and the clamping unit 5 will often use the same rack (not shown) arranged on the machine bed 3.
    An even simpler and very reliable method of coupling the axial position of the spindle unit 13 and the slide 33 is to arrange a coupling rod 39 between the spindle unit 13 and the slide 33. This coupling rod 39 ensures that the honing stones 21 and 37 always have the same axial position. In this case, for example, the drive of the slide 33 can be deactivated, so that the oscillating stroke movement of both the external honing device 31 and the honing tool 19 is performed exclusively by the spindle unit 13.
    It is also possible, in order to achieve a higher oscillation frequency, to control both the drives of the spindle unit 13 and the slide 33 in the axial direction and to use the coupling rod 39 as an additional security or to compensate for short-term differences in acceleration. In this case, the coupling rod 39 could be dimensioned smaller, since it only has to transmit small “difference” forces between the spindle unit 13 and the slide 33. In addition, the axial drive of the spindle unit 13 is relieved.
    As already mentioned, it is possible to either drive or lock both the spindle 17 and the clamping means 11. As a result, the honing machine 1 according to the invention offers a large number of possible operating modes, which are summarized below in table form.
    Fig. 2 shows the external honing device 31 with its cardanic suspension without the common drive.
    In Fig. 2 two honing stone holders 41 are shown, in which the honing stones 37, not shown, can be used. In addition, two sliding block holders 90 are shown.
    Overall, the external honing device 31 shown is designed such that four honing stones 37 (see FIG. 1) can be received and each can be advanced radially inward. Accordingly, eight honing stones 37 are used if the external honing device 31 has four honing stone holders 41.
    The radial infeed takes place via two toothed racks 43. Because the honing stones or the honing stone holder 41 are acted upon by a toothed rack 43 at their front and rear ends, the honing stones do not tilt and the honing stones are evenly removed Honing stones 37 achieved over their entire service life. This leads to an improved machining result and an increased removal rate.
    The pinions which drive the racks 43 are not visible in FIG. However, they are mounted on an axis of rotation, which in turn is driven by a reduction gear 45. The reduction gear 45 is preferably an epicyclic gear or another reduction gear. The first-mentioned gears are characterized by the fact that they enable a large reduction ratio, are self-locking and require low drive torques in order to be able to transmit the required feed force via the pinion (not shown) to the racks 43 and thus to the honing stone holder 41 or the honing stone 37.
    In FIG. 2, the input shafts 47 of the reduction gears 45 are shown. These input shafts 47 have a groove 49 which, similar to the slot of a screw, serve to transmit the required input torque. For reasons of clarity, the same components of the different linear drives are not always provided with the reference symbols.
    The linear drives are arranged between two structures 51, made for example of sheet steel, arranged parallel to one another. In Fig. 2, a first axis of rotation 53 is arranged vertically. The structures 51 and with them the linear drives of the external honing device are mounted in a ring 55 so that they can rotate about a first axis of rotation 53. The storage is not shown in detail in FIG. It is advantageously carried out using pins and corresponding bearing bushes.
    The ring 55 is arranged between the structures 51 and the pairs of racks 43. Two bearing journals 57, which define a second axis of rotation 59, are arranged on the ring 55. The first axis of rotation 53 and the second axis of rotation 59 form the cardanic suspension of the external honing device 31.
    Because the axes of rotation 53 and 59 lie in one plane and this plane runs in the middle of the honing stones or the honing stone holder 41, the result is an ideal force distribution of the honing stones or optimal contact between the honing stones and the workpiece to be machined.
    A further part of the external honing device 31 according to the invention is shown in FIG. 3. One recognizes the second axis of rotation 59 and the associated bearing bushes 61, which serve to receive the bearing journals 57 of the ring 55 (see FIG. 2).
    In Fig. 3, a carrier 63 is shown, which is arranged / attached to the carriage 33 (see Fig. 1). The associated fastening screws 65 are indicated in FIG. 3. In addition to a base plate 67, the carrier 63 comprises a frame 69.
    Two brackets 71, on which the bearing bushes 61 are arranged, are screwed to the frame 69. Four toothed belt pulleys 73, which can be driven via a toothed belt 75 and a drive motor 77, are arranged on the frame 69.
    When the drive motor 77 is activated, the toothed belt pulleys 73 rotate and with them a drive shaft 79, only one of which is visible in FIG. 3. At their rear end in FIG. 3, the drive shafts 79 have a flat surface 81 which engages in the grooves 49 of the input shafts 47.
    The transition of the drive movement from the fixed frame 69 to the cardanically mounted external honing device 31 takes place via spherical profiles with transverse pins on the drive journals, so that angular deflection is possible, but torque transmission to advance the honing stones 37 is still possible.
    Alternatively, the drive shafts 79 can be designed similarly to a conventional cardan shaft. In any case, they enable length compensation between the frame 69 or the carrier 63, which is firmly connected to the slide 33, and the structures 51 or the input shafts 47 of the four linear drives.
    It goes without saying that the geometric locations at which the toothed belt pulleys 73 or the drive shaft 79 are fastened to the frame 69 are selected such that the drive shafts are directed directly onto the input shafts 47 of the reduction gears 45.
    A further application of the honing machine 1 according to the invention, external honing, is shown in FIG. In this application, no honing tool 19 is provided, but rather the workpiece 7 is supported and driven in the spindle 17 of the spindle unit 13 with corresponding clamping means 87, 89. So that the opposite end of the workpiece 7 cannot move radially, it is received on a circumferential or stationary tip of a tailstock 85. The holding devices for the workpiece 7 essentially consist of two positioning plates 87 with a fitting that center the workpiece 7 on its inner diameter, a centering hole for the fixed tip of the tailstock 85 and a pin 89 which is clamped into the spindle 17 of the spindle unit 13 .
    Because the pre-set plates 87 are slightly smaller in diameter than the outside diameter of the workpiece 7, the honing stones 37 can extend beyond the end of the workpiece 7 during machining, so that a cylindrical geometry over the entire length of the workpiece 7 to be machined is safe and is achieved precisely. The rotary movement required for external honing is transmitted from the spindle 17 to the workpiece 7.
    In this application, the spindle unit 13 and the tailstock 85 cannot be displaced in the axial direction. The oscillating lifting movement during the external honing is carried out by the slide 33 of the external honing device 31.
    The linear drive or drives for the spindle unit 13, slide 33 and / or clamping unit 5 can e.g. be designed as a chain drive, rack and pinion drive, a hydraulic cylinder or a ball screw spindle.
    During external honing, a gimbal-mounted drive shaft is used for workpiece rotation. The system experiences a sufficient kinematic determination by the gimbal-mounted external honing tool and the reception of the workpiece in the tip or in the rotary clamping device.
    The honing machine 1 according to the invention can be operated in various ways.
    In (operating) mode 1, spindle unit 13 and external honing device 31 are moved exclusively axially at the same stroke speed. The rotational movement of the workpiece 7 is generated by the rotationally fixedly arranged rotational clamping unit 5.
    In mode 2, the spindle unit 13 and the external honing device 31 are stationary, but are arranged at a defined distance for the same axial position of the honing stones 21, 37. The rotary clamping unit 5 then takes over the lifting and rotating movement of the workpiece 7 by executing an oscillating movement in the axial direction. It can use the same rack mounted on the machine bed as the slide 33 and the spindle unit 13.
