[0030] The side clamping structure 3 includes a nut 301 fixedly installed on the inner wall of the cleaning box frame 2, a screw rod 302 is spirally driven inside the nut 301, one end of the screw rod 302 is located outside the cleaning box frame 2, and a cross handle rod 303 is fixedly installed on the outer wall; one end of the inner side of the screw rod 302 is rotatably installed with a mounting shaft disc 304, and a clamping rubber pad 305 is installed at the end of the mounting shaft disc 304 away from the screw rod 302;

[0031] A bottom clamping structure 4 is assembled in the middle of the clamping machine base 1. The bottom clamping structure 4 includes a vertical cylinder 401 installed on the surface of the clamping machine base 1, and a bottom clamping frame 402 is installed at the top output end of the vertical cylinder 401. A bidirectional lead screw 403 is rotatably installed inside the bottom clamping frame 402, and one end of the bidirectional lead screw 403 is connected to a servo motor 404. The servo motor 404 is fixedly installed on the inner wall of the bottom clamping frame 402, and the servo motor 404 is used to actively drive the bidirectional lead screw 403 to rotate.

[0032] Arc-shaped clamping screw blocks 406 are spirally driven on the outer sides of both ends of the bidirectional lead screw 403, and the arc-shaped clamping screw blocks 406 are slidably restricted inside the bottom clamping frame 402.

[0034] According to the above embodiments, the working principle of the present invention is as follows:

[0035] When clamping a stainless steel precision forging during processing, place the stainless steel precision forging on the bottom clamping frame 402 inside the cleaning box frame 2. After starting the servo motor 404, the servo motor 404 drives the bidirectional lead screw 403 to rotate.

[0036] Then, according to the shape of both sides of the stainless steel precision forging, rotate the horizontal number of the side clamping structure 3, and adjust the height of the stainless steel precision forging installed on the bottom clamping frame 402 through the vertical cylinder 401.

[0037] When the height of the stainless steel precision forging is adjusted to the position corresponding to the side clamping structure 3, manually rotate the cross-shaped hand lever 303.

Since the clamping length of multiple groups of stainless steel precision forgings can be adjusted arbitrarily, it is applicable to the clamping and positioning of stainless steel precision forgings with different shapes.
