Since the first lead screw is threadedly connected in the threaded hole, as ... The rotation of the lead screw causes the upper clamping block to slide downward. During the sliding process, the guide rod plays a limiting role in the guide groove. As the upper clamping block moves downward, the upper groove on the lower surface of the upper clamping block is stuck on the upper surface of the outer cylinder until the upper clamping block presses the outer cylinder downward. The inner sides of the lower groove and the upper groove are both provided with a first anti-slip pad, which plays a role of anti-slip and preventing the appearance of clamping marks on the surface of the outer cylinder. After the outer cylinder is clamped, the output end of the second servo motor is controlled to rotate right, and the second lead screw is driven by the second servo motor to rotate, so that the slider threaded on the surface of the second lead screw slides left in the groove, and at the same time drives the moving block and the second pad to move together, and the inner cylinder is pushed into the outer cylinder by the moving moving block and the second pad. During the working process, the device can clamp outer cylinders of different sizes by controlling the upper clamping block to move freely up and down. At the same time, the operation is simple and convenient, and it has the effects of anti-slip and preventing clamping marks, thereby achieving the purpose of practicality.
