The first electric telescopic rod 9 is activated, which drives the fixed rod 10 and the test piece to move downward to a suitable position inside the first placement box 19. The third electric telescopic rod 17 is activated, which drives the limiting plate 18 to move and no longer limits the test piece. The double-headed motor 12 is activated, which drives the lead screw 13 to rotate. The first slider 14, the second electric telescopic rod 15, and the limiting frame 16 on the lead screw 13 move in opposite directions to both ends, completing the placement of the test piece. When the test piece fails the inspection due to missing rivets under the support frame 27, the output end of the cylinder 2 is activated to extend back, which drives the rack 3 to move. The movement of the rack 3 drives the gear 7, the first rotating shaft 6, the first electric telescopic rod 9, and the fixed rod 10 to rotate in opposite directions to one side of the second placement box 20. The above operation is repeated to place the test piece. This device can unload the test piece after inspection, reducing the labor intensity of manual unloading. It can also classify and place qualified and unqualified test pieces for convenient centralized processing.
