In particular, the extension frame 610 is controlled to rise and fall on the plug-in column 2 613 by the lifting motor 614, thereby driving the rack frame 67 to rise and fall, thereby realizing the meshing switching between the driven gear 2 65 and the driven gear 3 66 and the matching rack 2 69 and the matching rack 3 68, thereby controlling the adjustment speed.

The clamping plates 402 are controlled by the motor 2 4010 and the bevel gear set 4011 to clamp and release the workpiece. If there is a deviation in the placement angle of the workpiece, the central gear 404 on the suspension plate 400 is driven to rotate by the motor 1 408 and the driving gear 409 set on the suspension column 4012, thereby driving the suspension plate 400 and the grasped workpiece to rotate as a whole, and the angle adjustment control is realized by combining the indicator needle 406 on the suspension column 4012 and the angle line 405 on the central gear 404, and the placement angle of the workpiece is actually adjusted as needed. The lifting plate 35 on the matching column 34 is controlled to rise and fall by the lifting cylinder 33, and the swing frame 36 rotatably installed on the lifting plate 35 is combined with the telescopic frame 38 to adjust the grasping angle of the end grasping adjustment mechanism 4, so as to flexibly adjust the grasping position according to the size of the workpiece. The end of the telescopic frame 38 is provided with a rotatably mounted mounting shaft 310, and the grabbing and adjusting mechanism 4 is suspended between the mounting shaft 310. After the grabbing and adjusting mechanism 4 grabs the workpiece, it is combined with the horizontal stabilizing component 41 to realize the horizontal stabilization of the grabbing and adjusting mechanism 4 as a whole, so as to avoid the grabbing and adjusting mechanism 4 from shaking during the adjustment process. The pitch frame 410 is clamped by the clamping groove 3100 on the mounting shaft 310. After the grabbing and adjusting mechanism 4 mounted on the mounting shaft 310 grabs the workpiece in combination with the suspension mechanism 3, the pitch frame 410 will rotate together with the mounting shaft 310 and the grabbing and adjusting mechanism 4. By rotatably mounting the telescopic cylinder 414 on the telescopic frame 38, when the telescopic cylinder 414 drives the push-pull frame 413 and the adjusting slider 412 to slide in the adjusting guide rail 411, the pitch frame 410 and the mounting shaft 310 will be controlled to perform pitch adjustment, and the pitch frame and the grabbing and adjusting mechanism 4 at the bottom will be kept in a horizontal posture in cooperation with the level ruler 416, so as to realize the horizontal grabbing and adjustment of the workpiece. A positioning scale line 110 is set inside the side guide rail 11 on one side, and the position of the workpiece on the conveyor belt 10 is positioned in combination with the positioning ray lamp 51 on the follower plate 50 on the other side. When the follower plate 50 moves synchronously with the rotating rod 56 and the connecting rod 55 and the suspension mechanism 3, the rays emitted from the positioning ray lamp 51 pass through the central lens 420 in the positioning frame 42 and irradiate on the positioning scale line, thereby accurately controlling the displacement stroke of the workpiece. At the same time, the blocking rod 53 can play a role in blocking and stopping the workpiece when the conveyor belt 10 transports the workpiece, thereby improving the adjustment efficiency of the precise stroke of the workpiece.By setting the annular rack 62 to drive the driven gear 1 64 to rotate, the driven gear 1 64 and the driven gear 2 65 are driven to rotate synchronously. When the driven gear 2 65 and the driven gear 3 66 are respectively meshed with the matching rack 2 69 and the matching rack 3 68, the rack frame 67 is driven to move at different speeds, and then the connecting frame 615 on the clamping slide 612 is driven to move at different speeds, thereby controlling the end push frame 616 to adjust the displacement of the workpiece, and realizing the fine adjustment and coarse adjustment control of the displacement of the workpiece. In particular, the extension frame 610 is controlled to rise and fall on the plug-in column 2 613 by the lifting motor 614, thereby driving the rack frame 67 to rise and fall, thereby realizing the meshing switching between the driven gear 2 65 and the driven gear 3 66 and the matching rack 2 69 and the matching rack 3 68, thereby controlling the adjustment speed.
