The device works as follows.

Parts 6 are stacked in magazine 5 (Fig. 2). The feed mechanism of the bottom part 6 of the stack in the store 5 is served

moving towards the turntable 2, through the spring 35 moves the body 34 with a rocking chair 54, the fingers 55 of which, entering the gaps between the teeth of the part 6, move it towards the turntable 2. The clamp 41 leaves the retention zone with its roller 43, and, turning on axis 40 under the action of springs- .2, the case 34 of the gripper 33 is pressed against the wall 6. At the same time, the roller 38 (FIG. 2 and FIG. 6), moving along the longitudinal groove 39, holds the gripper 33 in position so that the plane of the part 6 all the time is in the plane of the turntable 2. After d Hoist 6 will be brought to disk 2 so that its lead-in groove will be applied to the seating surface of disk 2, rod 30 (Fig. 6) will continue to move and, compressing spring 35, will attach part b to rotary disk 2 with the necessary tension . When fitting the parts to the disk. 2, they are skewed with respect to the arc surface of the disk 2 due to the difference in their sizes within the tolerance, for which it is necessary to align the part 6 on the seating surface of the disk 2. This is done as follows. After the movement of the gripper 33 in the direction of the disk 2 stops, the rod 30 continues to move, overcoming the resistance of the spring 35. Together with the rod 30, the sleeve 46 moves, and the rod 31 rigidly attached with the gripper 33 will remain in place and, with its shoulder 32, will act on the firing pin 51, pulling it back into the sleeve 46, and when the inlet 47 opens, the air under pressure enters the collar 50, tearing the firing pin 51 from the surface of the collar 32 of the rod 31, will bring it back in an accelerated motion until the radial channels 53 vehicle with intake with the hole 47. At the same time, the compressed air through the channels 53 and 52 will enter the cavity under the end face of the striker 51. Since the end face of the striker 51 is much larger than the area of the collar 50, the striker 51 will move forward sharply in the direction of the rod 31 and strike at it on both sides of the ends of the striker 51 are connected by channels 52 and 53 and through openings 48 with the atmosphere, while the pressure under the ends of the striker 51 drops and the pressure under the collar 50 again pushes the striker 51 back. The cycle is repeated several times until the part b is fully mounted on the disk 2. At the same time, the rocking chair 54, the self-aligning oval hole 56 (Fig. 7) on the axis 57, adjusts the magnitude of the force of the impacts so that the force more blows to that part of part 6, which has not yet fully become on the seating surface of disk 2. After final fixing of part 6 on disk 2, the nozzle 8 mechanism is disconnected 8. its gripper 33 returns to its original position to receive the next part, and the rotation mechanism 3 ( Fig. 1) by including power

the cylinder 60 with the pawl 63 will turn the ratchet 59 and with it the disc 2 into a step for securing the next part.

With part 6 on disk 2 in

the area of the grinding heads is processed by its side surfaces, and when the part 6 enters the zone of action of the removal mechanism, it is turned on. Prk this cylinder 10 (. 3) pushes the rod 14 B towards the disk 2, and the roller 27, rolling on pattern 26, will turn the cylinder O on the pins I and install its axis in the plane of the disk 2, With further movement the rod 14, moving the body 15 puller 16 with eccentrics 20, will cause

turning the tongues 21 around the axles 22 and leading the eccentric 20 to the lateral surfaces of the part 6. When the rod 14 moves backward, the part will be clamped by 6 eccentrics. 20 and remove it from disk 2, and then roller 27. Moving along pattern 26, the cylinder 10 moves away toward the tray with the processed parts. Upon further movement of the rod 14, the pins 24, mounted on the rods 23, reach the end of the groove in the rods 25. The movement of the rods stops.

5 23, and the eccentrics 20 will be disassembled in opposite directions, freeing part 6, which will fall into the tray. The cycle of the submission of parts, fixing it, processing and removal is completed. This happens in the automatic mode, the sequential fixing of parts supplied from the magazine on the rotary disk, abrasive processing of their side surfaces, removal of parts from the rotary disk and removal of them on the tray.
