When the clamp opens to a certain distance, it will fit against the upper end of the second disc. The continued downward movement of the clamp will drive the second disc to move downward. The downward movement of the second disc will compress the fourth spring. Since the lower end of the third stopper fits against the bottom plate, it will move relative to the third stopper when the second disc moves downward. The second disc moves downward until it is flush with the upper surface of the third stopper. At this time, the third inclined slider will slide on the inclined surface of the fourth inclined slider to the bottom end of the fourth inclined slider, so that the second spring will drive the clamp to clamp the processed gear on the third stopper.

When the hydraulic cylinder drives the third inclined slider to move downward, it will slide on the upper inclined surface of the fifth inclined slider, and the bottom end of the movable block will contact the upper end of the cushion block, so that the third inclined slider can slide from the upper inclined surface of the fifth inclined slider to the lower inclined surface. The sliding of the third inclined slider on the upper inclined surface of the fifth inclined slider will drive the clamp to open. The opening of the clamp will place the processed gear on the upper end of the workbench.

Gears to be processed are stacked in the feed pipe. When the second disc rotates half a turn, a gear to be processed will fall into the feed pipe and enter the upper end of the third stopper in the circular hole, thereby completing automatic feeding to the upper end of the third stopper in the circular hole.

[0022] (3) When the clamp of the present invention clamps the gear to be processed to the upper end of the workbench, the clamp opens to place the gear to be processed on the upper end of the workbench. At this time, the third inclined sliding block continues to move downward to drive the clamp to move to the lower end of the workbench, and the second disc drives the clamp to rotate a quarter of a turn. The gear to be processed is loaded and unloaded repeatedly in this way, with a high degree of automation, a simple structure, and a low cost of use. BRIEF DESCRIPTION OF THE DRAWINGS
