Then the operator starts the feeding pneumatic cylinder 402, which will make the feeding pneumatic cylinder 4 02 drives the movable plate 406 and the feeding plate 410 to approach the first mounting plate 200. At this time, the feeding plate 410 can push the workpiece on the loading plate 210 between the workpiece placement table 300 and the cover plate 302. The operator can adjust the height of the positioning plate 304 by turning a plurality of bolts 305 to achieve the function of limiting the workpiece. When the feeding pneumatic cylinder 402 is started or the pneumatic cylinder 405 is driven, the movable plate 406 will drive the connecting rod 409 to slide inside the limiting groove 408. Through the cooperation of the limiting groove 408 and the connecting rod 409, the movement of the anti-drop plate 407 and the feeding plate 410 is limited. The length of the process, and then the operator can start the double-head tapping machine 102, which will tap the workpiece. At this time, the driving pneumatic cylinder 405 is started to move away from the first mounting plate 200. Through the continuous feeding of the loading plate 210 and the continuous movement of the feeding plate 410, the automatic tapping effect can be achieved. The tapped workpiece will fall into the interior of the operating table 100 through the lower hopper 411 due to the feeding plate 410 pushing the new workpiece.
