    Description [0001] The present application relates to a multi-function machine for the mechanical processing of complex parts usable for example in the sectors of eyewear, watchmaking, jewelry, connectors, electronics, dental, medical and various accessories.
    [0002] Some production machines of the Bumotec company, model S 90, of the Almac company, model FB 1005 and of the company Willemin-Macodel, model W 158 are known in the field of mechanical machining of complex parts.
    [0003] These machines are equipped with a spindle bearing spindle which has freedom of movement along two axes (the vertical axis and the transverse axis) and is able to work, by means of said spindles, on a bar of long dimensions, which must be variously inclined on a horizontal plane during the operations to which it must be subjected.
    [0004] A drawback found in the prior art described above consists in the fact that the continuous vertical movement of the spindle carrying spindles, due to the high weight of the same, puts the screw of the axle under continuous stress, thus jeopardizing the precision of the machine, which therefore must be subjected to frequent, expensive, long and complex ordinary and extraordinary maintenance to restore the correct and essential precision of the machine itself, complicated by the fact that the machine components are difficult to reach.
    [0005] A further drawback found in these machines of the known type consists in the fact that they occupy a large size, not only due to the real size of the machine, but also to the size of the empty space around the machine which must be provided to carry out the inclination operations of the bar during its working.
    [0006] Furthermore, the inclination to which these long bars are subjected during their processing entails a high risk of accidents due to the sudden changes of inclination of the bar during its processing which creates a dangerous situation for the operators.
    [0007] The main task of the present invention is therefore to solve the technical problems mentioned, eliminating the drawbacks of the cited prior art and therefore devising a multi-function machine for the mechanical machining of complex parts which is simple and easy to use. use and which requires reduced ordinary and extraordinary maintenance as well as rapid and easy maintenance.
    [0008] Within the scope of the aim described above, another important object of the invention is to provide a multi-function machine which requires the determination of reduced overall dimensions for its use.
    [0009] Another object of the invention is to provide a multi-function machine which allows it to be used in conditions of safety for the operators.
    [0010] Another object is to provide a multi-function machine which is structurally simple, which has low manufacturing costs and can be made with the usual known systems.
    [0011] The aim and the objects mentioned, as well as others which more clearly will appear later on, are achieved by a multi-function machine (1) for the mechanical processing of complex pieces which is characterized by the fact that it consists of a bar holder (2 ), above a double decanting tank (4), movable according to a rotation axis A and a vertical axis Z, and provided with means for the rotation and axial displacement of a bar (6), called multi-function machine ( 1) being constituted by a main body (7), placed frontally to said bar holder (2), comprising a rotary table (11) which supports a counter-table (24), movable along a horizontal axis X, on which a slide is present (25) spindle holder, movable according to an orthogonal axis Y, supporting a plurality of spindles (26) and a cut-off (27), said main body (7) comprising an arm (28), fixed to said rotary table (11), to support the work piece on said bar (6) in the activation phase of said cutter (27) due to its separation from said bar (6), said main body (7) comprising a turret (31), positioned between said bar holder (2) and said table rotary (11), supporting a system for advancing and sealing (33) of said bar (6), movable according to said vertical axis Z and according to said axis of rotation A, said multifunction machine (1) comprising an electrical cabinet (37) , positioned in an area adjacent to said main body (7).
    [0012] Further characteristics and advantages of the invention will become apparent from the detailed description of a particular, but not exclusive, embodiment, illustrated by way of non-limiting example in the accompanying drawings, in which: FIG. 1 shows the multi-function machine in a side view; fig. 2 illustrates the multi-function machine in a particular; fig. 3 shows, in a front view, the multi-function machine, in a detail, with the pneumatic arm lowered; fig. 4 shows, in a front view, the multi-function machine, in a detail, with the pneumatic arm raised; fig. 5, 7, 9 and 10 show, in a view from above, the rotating table with the C axis respectively in position (-30) degrees, 0 degrees, (+30) degrees and 0 degrees; fig. 6 and 8 illustrate, in a view from above without the slides, the rotating table with the C axis respectively in position (-30) degrees and 0 degrees.
    [0013] In the embodiments that follow, individual characteristics, given in relation to specific examples, may actually be interchanged with other different characteristics, existing in other embodiments.
    [0014] It should also be noted that everything that was already known during the patent obtaining procedure is not intended to be claimed and the subject of an excerpt (disclaimer) from the claims.
    [0015] With reference to the aforementioned figures, the number (1) has been used to indicate a multi-function machine for the mechanical processing of complex pieces that can be used, for example, in the fields of eyewear, watchmaking, jewelery, connectors and electronics. of the dental or medical sector and various accessories.
    [0016] The multi-function machine (1) consists of a bar holder (2), supported by an underlying bar-holder support (3), both above a double decanting tank (4) for recovering the shavings, the oil cutting and its recirculation.
    [0017] The bar holder (2) rotates according to a rotation axis A and is driven in a direct engagement according to a vertical axis Z through a plurality of rods and / or a lever system (5), located inside said bar-bearing support (3).
    [0018] The bar carrier (2) moves on a skid-like slide and is equipped with means for the rotation and the axial displacement of a bar (6), preferably having a length of 4 meters, or of strips or profiles wrapped in skein to increase production autonomy.
    [0019] In particular, the bar carrier (2), by means of a recording system, allows an alignment of the bar (6) or of the strips or profiles, in the desired position, with a very high precision.
    [0020] Inside the bar support (3) there is a counterweight to compensate for the gravitational mass of the vertical axis Z and of the bar holder (2).
    [0021] The multi-function machine (1) consists of a main body (7), positioned frontally to the bar holder (2) and supported at the bottom by an electro-welded base (8) which has a substantially box-like conformation and made with steel sheets having a plurality of ribs and a consistent thickness.
    [0022] The base (8) is able to increase the static and dynamic rigidity of the multi-function machine (1), reduces deformations and allows an increase in the speed of the axes.
    [0023] The base (8) is firmly associated at the top, by means of a plurality of connection and fixing means, with a supporting platform (9), supporting all the moving parts of the main body (7) of the multi-function machine ( 1), which therefore guarantees maximum stability to the multi-function machine (1).
    [0024] The platform (9) is superiorly provided with three support points (10a, 10b, 10c) on which a rotary table (11) is rotatably connected, having a substantially semicircular conformation in plan view.
    [0025] The support points (10a, 10b, 10c) are placed at the vertices of an imaginary isosceles triangle inscribed in the semicircle of the rotating table (11).
    [0026] The rotary table (11) centrally presents a centerpiece (12) which constitutes the central axis around which the rotation of said rotary table (11) takes place, according to a rotation axis C, from (-30) degrees to (+30) degrees.
    [0027] The rotation of the rotary table (11) from (-30) degrees to (+30) degrees is defined by a numerical control device (13), located in an area adjacent to the main body (7), through a system mechanical that transforms a linear movement into a circular movement.
    [0028] In particular, on the platform (9), in the opposite direction to said bar holder (2), a fixed base (14) is presently present, on which a motor (15) is stably present which, by means of a belt (16 ), rotates a ball screw (17) which moves a nut-bearing guide (18) along an axis parallel to said base (14).
    [0029] The nut-carrying guide (18) has a slit (19) longitudinally within which a pin (20) projecting perpendicularly to a bracket (21), radially protruding outside said rotary table (11), runs and is guided substantially of a diametrical axis passing through said support point (10b) and for said centerpiece (12).
    [0030] The numerical control (13) therefore defines the working position of the rotary table (11) by actuating the motor (15), the belt (16) and the ball screw (17), moving the nut-carrying guide ( 18) which requires movement, by means of the bracket (21), to the rotary table (11) according to the axis C, in the desired position.
    [0031] In the condition in which the rotary table (11) makes a rotation according to the axis C such as to be positioned at (-30) degrees, illustrated in figs. 5 and 6, the nut-carrying guide (18) is positioned at a first end (22) of the ball screw (17), while the pin (20) is located at one end of said slit (19) adjacent to said rotary table (11).
    [0032] In the condition in which the rotary table (11) makes a rotation according to the axis C such as to be positioned at 0 degrees, illustrated in figs. 7, 8 and 10, the nut-carrying guide (18) is positioned substantially at half the length of the ball screw (17), while the pin (20) is positioned at the end of said slot (19) furthest from said rotary table (11).
    [0033] In the condition in which the rotary table (11) makes a rotation according to the axis C such as to be positioned at (-30) degrees, illustrated in fig. 9, the nut-carrying guide (18) is positioned at a second end (23) of the ball-bearing screw (16), opposite to said first end (21), while the pin (20) is positioned at the end of said slit (19) adjacent to said rotary table (11).
    [0034] The rotary table (11) supports a counter-table (24), movable along a horizontal axis X, which in turn supports a spindle carrier (25) which moves frontally along an orthogonal axis Y, above said counter-table ( 24).
    [0035] The slide (25) is able to support a plurality of mandrels (26) and a cut-off (27).
    [0036] In the particular illustrated embodiment, by way of non-limiting example, the slide (25) supports fifteen mandrels (26) and a cut-off (27), of which six horizontal mandrels (26a), three upper vertical mandrels (26b) , three lower vertical spindles (26c), three lateral spindles (26d) and a telescopic mandrel (26e) of said cutting-off machine (27).
    [0037] The main body (7) comprises a pneumatic arm (28) consisting of a first wing (29a), permanently connected to said rotary table (11) in correspondence with the resting point (10c) facing the three lateral spindles (26d), and by a second wing (29b), movable, provided at its terminal end with a first gripper (30) extensible according to the horizontal axis X; said first gripper (30) is adapted to lock the machined piece, associated with said bar (6), upon activation of said cutter (27).
    [0038] In the condition in which the arm (28) is at rest, illustrated in fig. 3, said first and second wing (29a, 29b) are placed parallel to each other, so that the cutting-off machine (27) does not affect the working area of the bar (6).
    [0039] In the condition in which the arm (28) is activated, shown in figs. 4, 9 and 10, i.e. during the operation of cutting the bar (6), once worked, by means of the cutting-off machine (27), said first and second wings (29a, 29b) are placed orthogonally to each other, and the first gripper (30) is completely elongated in order to block said worked piece in the desired position.
    [0040] The main body (7) further comprises a turret (31), supported by said platform (9) and positioned between said bar carrier (2) and said rotary table (11).
    [0041] The turret (31), having a double-walled team-shaped conformation, supports a vertical slide (32) on which runs a feeding and holding system (33) of said bar (6), movable according to 'vertical axis Z and rotating at 360 degrees according to the rotation axis A.
    [0042] The advancement and sealing system (33) of said bar (6) is provided with a divider (34), also movable along the vertical axis Z and rotating 360 degrees according to the rotation axis A , to lodge inside a second clamp (35) of high pressure hydraulic clamping, with L closure.
    [0043] At the rear of said divider (34) there is a hydraulic system (36) with high feed and rotating locking pressure of the bar (6).
    [0044] The multi-function machine (1) further comprises an electrical cabinet (37) positioned in an area adjacent to said main body (7).
    [0045] All the parts of the multi-function machine (1), with the exception of the base (8), are obtained from G25 cast iron castings, having a plurality of ribs and a substantial thickness, which are subjected to stabilization treatments which contribute to increasing the static and dynamic rigidity of the multi-function machine (1), thus reducing deformations and allowing an increase in the speed of the axes.
    [0046] In its use the multi-function machine (1) is programmed and managed by the numerical control device (13) that manages the rotation axis A, the vertical axis Z, the horizontal axis X, the orthogonal axis Y and the rotation axis C and all the other functions of the multi-function machine (1), such as for example the electrical, hydraulic and pneumatic functions.
    [0047] The advancement and sealing system (33) and the divider (34) are programmed and managed by the numerical control device (13) and synchronized with the other functions of the multifunction machine (1).
    [0048] A recording system allows a very high-precision alignment of the bar (6), supported by the bar holder (2), with the axis of the divider (34), so as to proceed with the processing of the same by means of the plurality of spindles (26).
    [0049] After the bar (6) has been worked the pneumatic arm (28) is activated, placing said first and second wing (29a, 29b) orthogonally to each other and extending completely the first pincer (30) in order to block said piece worked in the desired position, so that the miter saw (27) cuts it.

    Claims (15)
    [1]
    [0050] At the end of the cutting operation, while the pneumatic arm (28) carries away the finished piece, the advancement and sealing system (33) of said bar (6) is activated in order to advance the part of the bar (6) which must undergo subsequent processing, the pneumatic arm (28) moving into a vertical position, as shown in fig. 3. [0051] Before releasing the workpiece, it is possible to perform shooting operations on the cut face, in masked time. [0052] The bar (6) is thus always lying in correspondence with the same position, its processing taking place through the rotation of the rotary table (11) which supports the various spindles (26) for the working of the bar (6) itself. [0053] It has thus been found that the invention has achieved the above-mentioned aim and objects, as a multi-function machine (1) has been obtained which requires reduced overall dimensions during its use since the bar (6) only moves on the horizontal axes X and vertical Z and does not make movements on horizontal planes during the machining operations of the same; in fact it is the task of the plurality of spindles (26) and of the cutting-off machine (27) to move around the bar (6), particularly along the horizontal axis X, on which the counter-table (24) slides, along the orthogonal axis Y, on which the slide (25) moves and along the rotation axis C, on which the rotary table (11) moves. [0054] The weight to be moved along the vertical axis Z corresponds to that of the vertical slide (32), of its mechanisms, of the bar holder (2) and of the bar (6) itself, whose weight is also partly compensated by the counterweight housed inside the bar support (3), and therefore does not correspond to the weight of the chuck (25) for spindles, as in well-known machines, considerably heavier; this leads to a substantial reduction in routine maintenance, since the vertical axis Z screws are not put under continuous effort by the weight they must support and therefore do not affect the precision of the multi-function machine (1). [0055] Furthermore, it has been verified that the multi-function machine (1) requires reduced and rapid and easy extraordinary maintenance, since all the parts of the multi-function machine (1) are easily accessible thanks to openable covers and protections. [0056] Furthermore, the multi-function machine (1) allows it to be used in conditions of safety for the operators, since the only vertical movement along the axis Z of the bar (6) eliminates the risk of accidents due, in machines of the known type , to the sudden inclination of the same during the working phase, and therefore the operator can also place himself at the side of the bar (6) without fear of being hit by it. [0057] It has moreover been verified that the multi-function machine (1) allows to achieve a high productivity, since it is possible to work bars in rolls or profiles wrapped in skeins, increasing the production autonomy of the machine itself and reducing the strid of each end bar. [0058] It has also been found that the multi-function machine (1) has a simple and easy use, has a very high and constant precision, has a robust and reliable mechanism and has an easy to use and rapid programming control, thanks to the device of numerical control (13). [0059] Furthermore, it has been found that the multi-function machine (1) guarantees a very high stability since the platform (9), supporting all the components of the main body (7) in movement, such as the counter-table (24), the slide (25 ) and the rotary table (11), is stably associated with the base (8) which is able to increase the static and dynamic rigidity of the multi-function machine (1), and therefore the stability of the machine itself. [0060] Furthermore, the base (8) and the cast iron castings of the other components of the multi-function machine (1), in addition to increasing the static and dynamic rigidity of the machine itself, reduce deformations and allow an increase in the speed of the axes. [0061] Finally, it has been found that the architecture of the multi-function machine (1) as a whole creates a thermo-symmetrical structure that reduces any inaccuracies due to heat. [0062] The materials used, as well as the dimensions that constitute the individual components of the invention, may of course be more pertinent according to specific requirements. [0063] The different means for carrying out certain different functions will certainly not coexist only in the illustrated embodiment, but may be present per se in many embodiments, even if not illustrated. [0064] The characteristics indicated as advantageous, appropriate or the like may also be omitted or be replaced by equivalents. claims
