    The present invention relates to a finishing unit with position adjustable copying device.
    In particular, the present invention relates to a Abrundaggregat with copying device, the location of which is remotely controlled and / or automatically adjustable to avoid production stops.
    Today rounding units are already known, which are equipped with position adjustable copying devices, that is, their relative position to the cutter of the finishing unit is adjustable to take into account the play that can occur in the kinematic chain between the cutter and the copying device, and / or wear to balance the cutter.
    In particular, in Abrundaggregaten with 2 motors, the position of the copying device relative to the cutter each adjustable so that it can be optimized in the two opposite working positions of the finishing unit.
    These finishing units include a rounding unit having a copying device mounted on an arm capable of pivoting between two limit positions relative to the mill.
    These limit positions are defined by adjustable limit stops to accordingly adjust the position of the copying device relative to the mill when in the machining position.
    When the finishing aggregate is in this position, that is, when the rounding unit contacts the first surface of the workpiece to be machined, the copying device is moved until it reaches the end position stop, due to the interaction with the workpiece itself and the counteraction with elastic means reached, which corresponds to a first job.
    In this first working position, the point of contact of the copying device with the first surface to be machined is aligned with the point of contact between the mill and the surface to be machined so as to allow the machining carried out by the miller to make a precise transition, with no discernible gradations, between the first To obtain area and the rounding to be generated.
    When the Abrundaggregat is arranged to edit the second surface of the workpiece, the copying device is brought due to the interaction with this surface and the counteraction with said elastic means in a second working position, in which the contact point of the copying device with the second to be machined Surface is aligned with the point of contact between the mill and this second surface to be machined.
    In other words, since two positions of the copying device are preset relative to the mill, the copying device will spontaneously either take one or the other of these positions, depending on which side of the rounding unit is brought into contact with the workpiece, that is depending on whether it is brought into contact with one or the other of the surfaces to be processed.
    A disadvantage of such a finishing unit with two motors of the known technique is that the copying device exerts a not always negligible, emanating from the elastic means stress on the material of the workpiece to be machined or the profile of the edge to be rounded.
    Therefore, in the area of edge processing of plates, there are known devices of rounding units which, in the event that the plate has a radiating profile of the edge ends, are adapted to work with stations of the aggregate equipped with molded profile tools for that purpose are designed to copy front and rear, the radial end profile of the plate edge ends.
    Furthermore, devices are known which make it possible to simultaneously manage a plurality of radii and a plurality of edge thicknesses.
    Therefore, the problem underlying the present invention is to allow a precise and optimal repositioning of the copying device relative to the milling machine as a result of the change of the surface to be processed, without this repositioning being dependent on the interaction of the copying device with the workpiece to be machined.
    Main object of the present invention is the realization of a finishing unit with position adjustable
    Copying device, which provides a solution to the above-mentioned problem and eliminates the disadvantages of Abrundaggregate described above.
    Within the scope of this task, the object of the present invention is to provide a finishing unit with a position-adjustable copying device, which enables the automatic adjustment of the position of the copying device relative to the tool.
    An object of the present invention in this context is therefore to automate the apparatuses for fine adjustment of the copying device relative to the tool, both in terms of machining tolerances, and in relation to the management of multi-radius tool profiles for which different corrections depend on may be required in each case for the radius selected for the processing.
    Another object of the present invention is to realize a finisher with a position adjustable copying device, which has a simple and reliable structure.
    This object, as well as these and other objectives, which will become apparent from the following description, are achieved with a finishing unit with position adjustable copying device according to the appended patent claim 1.

    With particular reference to the aforesaid figures, reference numeral 10 designates a finishing unit with position-adjustable copying machine 11, comprising: a frame 12; a tool 13 fixed to the frame 12 relative to which it is rotatable about a working axis A.

    In other words, the desired working condition provides that the machining performed on the machining edge 13a provides a transition, without appreciable gradations, between the flat surface C of the surface of the workpiece 15 to be machined, on which the copying device 11 is in contact, and by the effect of the tool 13 produced curved surface D.
    According to the invention, the finishing unit 10 has a specific feature which consists in including a driving device 16 which serves to adjust the position of the copying device 11 relative to the tool 13, independently of the interaction of the finishing aggregate 10 with the workpiece 15 to be machined.
    According to a first embodiment of the present invention, of which FIG. 4 shows an example, the drive device 16 is advantageously configured to rotate the copying device 11 relative to the tool 13 about a pivot axis E which is parallel to the working axis A.

    The drive device 16 is advantageously configured such that, in use, translational movement of the movable member 20 is followed by movement of the pusher member 19, which movement causes the holder 18 to move relative to the frame 12, which is proportional to the translational motion. to move the copying device 11 relative to the tool 13.
    In a preferred embodiment of the present invention of no exclusive character, of which Fig. 5 shows an example, the holder 18 is advantageously fixed to the frame 12 and elastically deformable to move the copying device 11 relative to the tool 13, that is either to shift and / or rotate linearly.
    In an alternative embodiment, shown by way of example in FIG. 4, the support is rigidly secured by pins to the frame 12 so that it can be rotated about a pivot axis E relative thereto.
    In general, the movable member 20 preferably includes a wedge-shaped portion 20a, and the pushing member 19 includes a portion adapted to engage with the wedge-shaped portion 20a.
    The thrust element 19 is preferably a ball or has a spherical head.
    According to the embodiment shown in Fig. 4, the movable member 20 includes a rod 21, which can slide guided along a direction orthogonal to the working axis A direction.
    This rod 21 has a conical neck which forms the wedge-shaped portion 20a.

    The guide receptacle extends along a direction transverse to the working axis A and has two opposing openings 23a, 23b, wherein protrudes through a first 23a of the two the thrust element 19 and is in contact with the holder 18.
    The pusher 19 protrudes through a second 23b of the openings 23a and 23b so as to engage the wedge-shaped portion 20a.
    Operatively causes a displacement of the rod 21 in a predetermined direction of actuation G, by the action of the wedge-shaped portion 20a, the pushing of the thrust member 19 through the guide receptacle 22 therethrough.
    Thus, the pusher 19 acts on the holder 18 and thereby causes the displacement of the copying device 11 relative to the tool 13th
    A predetermined displacement of the rod 21 corresponds to a proportional displacement of the holder 18, so that the position of the copying device 11 is precisely adjustable via the movement of the rod 21.
    Preferably, a return spring 24 acts on the rod 21 to bring it back into a predetermined rest condition.
    Advantageously, the linear actuator 17 is hydraulically operated to be controlled remotely or automatically.
    Preferably, the linear actuator 17 is controlled in feedback, for example via proportional valves, to control the value of the thrust, preferably continuously.
    Thus, it is possible to automatically adjust the position of the copying machine 11 without interrupting production.
    In the embodiment of the invention shown by way of example in Fig. 5, the frame 12 includes a stop member 23 and the pusher 19 is wedge-shaped and inserted or insertable between the stop member and the holder 18, about the holder 18 due to the insertion / extraction of the pusher 19 between the
    Stop element 23 and the bracket 18 to move reversibly relative to the stop element 23.
    The stopper member 23 preferably includes a roller facing a base member 18 a of the holder 18.
    This also includes a support arm 18b, which carries the copying device 11..
    The base element preferably consists of an elastically yielding material and advantageously consists of a parallelepiped which has internal boreholes for promoting its deformability along the translation direction F.
    Also in this embodiment acts, preferably on the thrust element 19, a rod 21 of the linear actuator 17th
    On the thrust element 19, the movable member 20 of the linear actuator 17 acts.
    The abutment member 23, the base member 18a, the pusher member 19 and the movable member 20 are arranged in such a configuration that advancement of the movable member 20 in a predetermined direction H causes jamming of the pusher member 19 between the abutment member 23 and the base member 18a, so that the latter is thereby deformed and the copying device 11 is displaced relative to the tool 13.
    Also in this case, the displacement of the movable member 20 can be automated to make it possible to adjust the position of the copying machine 11 relative to the tool 13 without interrupting the production.
