[0027] A transverse motor 14 is fixedly installed in the base 1, and a transverse screw 15 is rotatably installed in the base 1. One end of the transverse screw 15 is fixedly connected to the output shaft of the transverse motor 14, and a slide 16 is threadedly installed on the transverse screw 15.

The power connection method of each electrical device is an existing mature technology, which is a well-known technology for people in this field and will not be described in detail here.

[0035] When in use, the base 1 is fixed on the workbench. Common fixing methods include using bolts, screws or other fasteners to connect the base 1 to the workbench. When in use, the workpiece is placed between the two clamping blocks 4, and then the bidirectional motor 9 is started.

The threaded cylinder 6 can be driven to rotate by the driving motor 11 in conjunction with the driving gear 12 and the teeth 13, so that the suction cup 8 can be automatically moved and adjusted, with high automation efficiency and improved clamping efficiency. The clamping block 4 on the mounting frame 2 can be driven to move by the sliding seat 16 moving on the transverse screw 15, so that the position of the clamping block 4 can be accurately adjusted. It can ensure that the workpiece is accurately positioned and fixed in a predetermined position. By rotating the motor 17, the workpiece on the clamp 4 can be driven to flip, reducing the time required for manual or mechanical repositioning and adjustment of the workpiece during processing. This automated flipping process greatly speeds up the production rhythm, thereby improving the overall production efficiency. The limit rod 18 can slide along the groove 19 when the threaded rod 7 moves, guide the threaded rod 7, and prevent the threaded rod 7 from rotating with the threaded tube 6.
