A moving assembly 4 is installed between the clamping arc plate 301 and the clamping platform 1, and a clamping plate 304 is movably installed inside the fixed box 303. One end of the clamping plate 304 close to the axis of the clamping platform 1 is set in an arc shape, and one end of the clamping plate 304 is set inside the empty groove 302. A sliding groove 305 is opened on the top of the fixed box 303, and two fixed plates 307 are symmetrically installed on the top of the fixed box 303. The two fixed plates 30 7 are respectively arranged at both ends of the slide groove 305, a slider 306 is fixedly installed on the top of the clamping plate 304, a first screw 308 is rotatably installed between the two fixed plates 307, the first screw 308 is threadedly connected with the slider 306, one end of the first screw 308 is fixedly connected with the output shaft of the first motor 309, and the first motor 309 is fixedly installed on one of the fixed plates 307. After the clamping arc plate 301 partially contacts the outer wall of the irregular part, each first motor 309 is turned on to drive the multiple clamping plates 304 on the clamping arc plate 301 to move toward the outer wall of the part, so that the end of each clamping plate 304 contacts the outer wall of the irregular part, thereby expanding the clamping area and improving the clamping stability of the irregular part.

[0026] The moving component 4 includes a transverse plate 401 fixedly mounted on the bottom end of the clamping arc plate 301, a side plate 402 is provided below the transverse plate 401, and the side plate 402 is installed at an equal angle on the outside of the clamping platform 1, and a sliding block 404 is fixedly mounted on the bottom end of the transverse plate 401, and the sliding block 404 is slidably mounted inside the sliding groove 403, and the sliding groove 403 is opened on the side plate 402, and a second screw 405 is rotatably mounted inside the sliding groove 403, and the second screw 405 is threadedly connected to the sliding block 404, and one end of the second screw 405 is fixedly connected to the output shaft of the second motor 406, and the second motor 406 is fixedly mounted on the side plate 402, and irregular parts are placed between each clamping arc plate 301, and the second motor 406 is turned on to rotate the second screw 405, and since the second screw 405 is threadedly connected to the sliding block 404, the clamping arc plate 301 is driven to move toward the irregular parts, and the irregular parts are pre-clamped, and at the same time, it is convenient to clamp parts of different sizes.
