Abstract

WORKPIECES RECEPTION DEVICE FOR MACHINE MACHINE. IT INCLUDES AT LEAST ONE RECEPTION CONE 9 ON THE PIN 10 OF WHICH IS MAINTAINED AN INTERCHANGEABLE PLATE 6. AN INDEXING PLUG 13 FRONTALLY LINKED TO THE INTERCHANGEABLE PLATE 6 LOCATED IN A PREDETERMINED POSITION, ENSURES RECEPTION IN THE EXACT POSITION OF ' A PART TO BE MACHINED. THIS DEVICE ALLOWS THE QUICK INTERCHANGE OF THE ENTIRE INTERCHANGEABLE DEVICE FOR DIFFERENT WORKPIECES. APPLICATIONS ESPECIALLY TO TRANSFER CHAINS AND MACHINING CENTERS.

Description

The invention relates to a device for receiving workpieces.

  relates to a workpiece receiving device for a machining machine, transfer line, machining center or the like, In the case of a machining center or a transfer chain, it is necessary to be able to change tools and heads fully automatic in a time also

  in short, the readjustment of the workpiece holders to

  seeing new workpieces takes time and is costly

  despite the quick change elements used, disrupts the workflow in machining centers and transfer

machine stops.

  Consequently, the subject of the invention is a

  tif of the aforementioned type for quickly readjust a machining machine when changing the workpieces to achieve this purpose, according to the invention can be used in a bore of the device, provided with a conical section, a receiving cone of corresponding shape, which comprises on its trunnion coming out frontally of the device at least one apparatus element for receiving in exact position a workpiece Cer elements of apparatus can be, in the application according to the invention, Clamping jaws, fixing bolts, receiving pins, supports, additional parts or components

  According to a particular embodiment of the invention,

  As an interchangeable plate there is provided an interchangeable plate having indexing pins placed at each other in a predetermined position.

  in a simple and advantageous way the change of

  sin of machining center tools or transfer chains to

equipment changer.

  Instead of the painful tool change, it is enough,

  according to the invention, to remove from the device a cone of

  with an interchangeable plate and to introduce into the device a new receiving cone with a new interchangeable plate with a correspondingly arranged indexing pin The tools remain in the machining machine and no longer have to be

  set to the new coordinates.

  So that the interchangeable plate with the indexing pin does not come out of its central position relative to the receiving cone, according to one embodiment of the invention, it is possible to practice in the interchangeable plate a second bore into which a adjusting pin ensuring

blocking in rotation.

  In addition, the receiving cone can be locked in the bore of the device by an eccentric cam and it can be provided, to lock in rotation the position of the

  piece to be machined, at least two receiving cones, preferably

  FIG. 1, with each having an interchangeable plate and an indexing peg. The invention will now be described in greater detail with reference to an exemplary non-limiting embodiment with reference to the appended drawing of which:

  FIG. 1 represents in partial section the arrangement

  part receiving machine according to the invention; Figure 2 is a side view of the device of Figure 1, in the direction of the arrow II of said figure; Figure 3 schematically shows a part

a transfer chain.

  The device 1 for receiving parts essentially comprises the foot 2, the clamping part 3 intended to block the part 4 received and the receiving part 5 according to

  the invention for a receiving cone 9 with an internal plate

  changeable 6 In a blind bore 7 having a conical central section 8 is the receiving cone 9 which carries

  the interchangeable plate 6 on the trunnion 10 exiting

  The device of the device 1 The interchangeable plate 6 further comprises a second bore 11 into which an adjusting pin 12 connected to the device 1 is inserted, to ensure the locking

  in rotation Front projection is provided on the interchangeable plate

  6, in each respective position predetermined by the workpiece, an indexing pin 13 ensuring the reception

  of the workpiece in the exact position, the entire

  FIG. 1 comprises two reception cones 9 diagonally opposite

  with interchangeable plates 6 and pegs

  indexing 13, as shown in particular in Figure 2.

  The receiver 8 is blocked in the bore 7 by an eccentric cam (not shown) known per se. There is no need for other locking means to retain the interchangeable plate 6. The eccentric is in the area of the recess 17, If it is desired to introduce a new workpiece with new coordinates of the indexing bores in a machine of the transfer chain of the figure

  3 for a machining, for example a drilling, it is not neces-

  the tools in the machining machines to the new coordinates, but simply change the cone 9 with the interchangeable plate 6 by means of the eccentric cam In station 15 of the chain

  14 are, for example,

  exchange 16 spare parts of the device 1 is performed

  placement and blocking of the new interchangeable plate

  6 The device according to the invention is particularly suitable for machining centers and transfer chains, for which there are very often

  readjustment operations for a large number of varied parts.

  In the same way that the interchangeable

  6 can also be changed clamping claws,

  supports, additional parts or fixing elements

  with which parts are kept to be machined on the

  device in a fixed position during a machining process.
