Since the diameters of the cylindrical parts are different, the position of the cylindrical parts needs to be limited during the clamping process, so that the two sides of the center of the cylindrical parts are clamped, and the limiting mechanism can limit the cylindrical parts of different diameters, so that the two sides of the center of the cylindrical parts are clamped.

[0029] Furthermore, the first square nut 13 and the movable rod 2 are each provided with two groups, and a guide groove is opened on the surface of the movable rod 2, and the guide groove of the movable rod 2 is composed of a circular groove and a square groove.

[0032] Furthermore, a guide groove is opened on the surface of the base 1, the second bidirectional screw rod 31 is fixedly connected to the guide groove of the base 1, and two groups of second square nuts 32 are provided and slide on the guide groove of the base 1. The second bidirectional screw rod 31 simultaneously drives the two groups of second square nuts 32 to slide in opposite directions, so that the second square nut 32 drives the limit rod 33 to slide on the surface of the base 1.

[0034] Working principle: The first motor 11 drives the first bidirectional screw 12 to rotate through the output shaft, and the first bidirectional screw 12 drives the two sets of first square nuts 13 to move in opposite directions, so that the two sets of movable rods 2 move in opposite directions. The clamping block 28 on the movable rod 2 clamps the cylindrical part. When the clamping surface needs to be processed, the clamping block 28 is loosened on the cylindrical part, and the cylinder 26 is started at this time. The cylinder 26 drives the adjusting rod 25 to slide on the guide rod 24 through the piston rod. The guide rod 24 drives the first connecting rod 23 to move during the sliding process. The first connecting rod 23 is moved by The connecting column 22 slides on the surface of the movable rod 2, and the connecting column 22 slides on the surface of the movable rod 2 through the slider 21.

The adjusting rod 25 can adjust the height of the two groups of clamping blocks 28 at the same time, and the horizontal height of the clamping block 28 is kept consistent. After the clamping height of the clamping block 28 changes, the processing equipment can process the original clamping surface.
