SU93338A1 - Device for indexing machine spindles - Google Patents

Description

The invention is a device for indexing machine screws into a load period by means of a dividing disk mounted on the needle and a lock.

The known devices for indexing the spindles of the lathes in the non-loading period do not allow the .INII of automatically operating machines to load a part into the required position and unload them with a 180 ° rotation but with respect to the loading position without additional rotators on the conveyor.

The described device eliminates this drawback, which is achieved by means of two swinging diametrically located fillers, which in turn interact with the dividing disc. In this case, the alternate on-off switching off of the latches is carried out by cams mounted on the shaft, which is periodically set in rotation by various means, for example, by ratchet mechanism, etc.

FIG. 1 - bottom view of the device with the device; in fig. 2 is a sectional view along line AA in FIG. one.

The splinter / hard drive has a split-disk 2 with one socket. On both sides of the spindle diametrically uetanovle; There are two swinging latches 3 and 4 on the shaft. In the position. shown in the drawing, the fixture rests with its end on the slots of the disk 2, fixing the disk, and hence the spindle in a certain position.

Rollers 5 are reinforced on the rollers. They are driven by cams 6 and 7 mounted on the same shaft 8. Each roller is contacted by the cam 9 by eating dinner 9.

The cam shaft is rotated periodically from an electromagnet or a hydraulic cylinder by a ratchet mechanism or mechanically from a Maltese cross, or another mechanism with primary rotation.

In the position depicted on chaeotezh. the products are loaded onto the machine.

Upon completion of loading, the shaft 8 from the cam of% 1 and 1b and 7 turns is at the same angle and the lock 5 moves away from the disk 2. Then the spindles turn and the treatment of the parts T is performed.

At the end of the machining, the spindles start to spin slowly, the shaft 8 with the cams rotates again and releases the retainer 4, which indexes the spindles, with their end in the slot of the disk 2. In this position, the batch of the products is dispensed. When dispensing products from the machine, they are rotated by 180 ° around their axis relative to their position at loading.

For the cycle of the machine, shaft 8 with cams 6 and 7 makes one complete revolution.

Claims (2)

1. A device for indexing machine spindles during the loading period by means of a dividing disc mounted on the spindle and a retainer, characterized in that, in order to dispense parts from the machine in a position rotated 180 ° to the loading position, the device is equipped with two diameters spaced retainers, alternately interacting with the dividing disc. 2. The form of the device according to p. 1, from .4 and that with the purpose of eliminating errors in the position of both latches, alternately turning them on and off is carried out by cams fixed on one shaft} -, making from a ratchet or other drive with intermittent .m one revolution per chain of operation of the machine.
