The arc block 216 is slidably connected to the circular groove, so that the heat generated by the servo motor 211 when working can be discharged through the heat dissipation hole, and when the fixed plate 215 rotates, the arc block 216 is driven to slide in the circular groove, which can support and limit the fixed plate 215, so that the fixed plate 215 drives the clamping assembly 22 to rotate more stably.
[0033] See also Figure 1-7 The utility model provides a technical solution: the clamping assembly 22 includes a T-block 221, the T-block 221 is slidably connected to the right side of the fixed plate 215, the right side of the T-block 221 is fixedly connected to a connecting frame 222, the top of the connecting frame 222 is fixedly connected to a cylinder 223, the bottom of the cylinder 223 is fixedly connected to a clamping block 226, the front and rear sides of the connecting frame 222 are slidably connected to a movable block 225, the front and rear sides of the connecting frame 222 are threadedly connected to a fixing pin 224, the fixing pin 224 runs through the inside of the movable block 225, the clamping block 226 is arc-shaped, and the inside of the clamping block 226 Rubber pads are provided on the side, and three are provided on both the connecting frame 222 and the movable block 225.

[0034] Example 2
[0035] See also Figure 1-7, and on the basis of Example 1, it is further obtained that the sealing mechanism 3 includes a sealing plate 32, the sealing plate 32 is arranged on the front side of the clamping body 1, the rear side of the sealing plate 32 is in contact with the front side of the clamping body 1, the sealing plate 32 is internally threadedly connected with a fixing bolt 31, the rear side of the sealing plate 32 is fixedly connected to a fixing frame 33, the fixing frame 33 is internally fixedly connected with a fan 34, the rear side of the fixing bolt 31 is threadedly connected to the front side of the clamping body 1, four fixing bolts 31 are provided, and the four fixing bolts 31 are respectively threadedly connected to the inside of the sealing plate 32, so that the sealing plate 32 can be fixed by the fixing bolts 31 to ensure the stability of the sealing plate 32, and at the same time it is easy to install and disassemble, and the operation is convenient.
[0036] When the workpiece needs to be clamped, the workpiece is placed inside the connecting frame 222 and the cylinder 223 is started.

When the adjustment is completed, the fixing pin 224 can be used again to fix the connecting frame 222 and the movable block 225. When the movable block 225 slides inside the connecting frame 222, the connecting frame 222 will drive the T-shaped block 221 to slide on the right side of the fixed plate 215. The T-block 221 can be used to limit the connecting frame 222 to ensure the stability of the connecting frame 222. When other parts of the workpiece need to be processed during the processing, it is only necessary to drive the worm 212 to rotate through the servo motor 211, so that the worm 212 drives the rotating rod 213 fixedly connected to the worm gear 214 to rotate. When the rotating rod 213 rotates, it will drive the T-block 221 to rotate through the fixed plate 215, which can drive the workpiece clamped inside the clamping block 226 to rotate, thereby improving efficiency.
