[0033] The working principle of the present application is as follows: during the clamping of the clamping member 4, the worker first makes a basic judgment on the outer diameter of the clamping member 4, and synchronously adjusts the extension and retraction of the extension rods of the two air cylinders 35, during the extension and retraction of the extension rods, the distance between the connecting seat 31 and the connecting rod 34 is changed, so that the clamping blocks 33 on both sides of the support plate 2 are rotated to be away from or close to each other, after the preliminary position adjustment is completed, the clamping member 4 is placed between the clamping pads 36 fixedly connected to the inner side of the clamping blocks 33, the extension and retraction of the extension rods of the air cylinders 35 are further adjusted, until the clamping pads 36 clamp the clamping member 4, since the distance between the clamping blocks 33 on both sides of the air cylinder 35 can be adjusted synchronously through the extension rods of the air cylinder 35, the clamping assembly can be matched with clamping members 4 of different diameters, and the application range of the clamping assembly is improved.

[0034] When the side surface of the clamping member 4 needs to be machined, the extension rods of the air cylinders 35 on both sides of the clamping assembly are slightly extended, so that the clamping member 4 can slide between the clamping pads 36, at this time, the adjusting rod 54 of the adjusting mechanism 5 is rotated, the adjusting rod 54 drives the adjusting disc 53 to push the pressure disc 532, the pressure disc 532 is connected with the bottom of the clamping member 4, and the clamping member 4 can be slowly pushed out by slowly rotating the adjusting rod 54, so that the worker can adjust the extension length of the clamping member 4 according to the need, so as to determine the side surface machining position, after the position is determined, the adjusting rod 54 is stopped, and the air cylinder 35 is started again, the clamping blocks 33 are driven by the two air cylinders 35 to stably clamp the clamping member 4 after the adjustment position, which is convenient for the worker to process the side surface of the clamping member 4.

[0035] When the angle of clamping component 4 needs to be rotated according to the processing position, the operator first rotates the fastening pin 9 to a state where it is disengaged from the rotating component 6. Then, the rotating component 6 is in a rotatable state. By rotating the rotating component 6, the main board 1, which is fixedly connected to it, is rotated, thereby rotating the clamping mechanism 3 installed on the lower surface of the support plate 2 until the clamping component 4 is rotated. After rotating to the predetermined angle, the fastening pin 9 is fixed again with a hex wrench, so that the screw part of the fastening pin 9 is reconnected to the adjustment hole 63 of the rotating component 6, thus completing the re-fixing of the clamping assembly after rotation. This facilitates meeting the operator's processing needs for adjusting the rotation angle of clamping component 4. In addition, two fastening pins 9 are threadedly connected to both sides of the block 72 to improve the stability of the clamping assembly after rotation adjustment.
