[0025] It is worth mentioning that the workpiece is clamped by the first clamp 2 and the second clamp 3, the second clamp 3 is pushed to move to the first clamp 2 by the driving device, and the workpiece is clamped, specifically, the rotating rod 8 is driven to rotate along the rotating seat 9 by the extension and retraction of the cylinder 10, and then the push rod 7 drives the pushing assembly to move left, and the second clamp 3 is moved.

[0026] In some possible embodiments, the first clamp 2 and the second clamp 3 are the same structure, the first clamp 2 and the second clamp 3 both include a shell 11, a plurality of adaptive blocks 12, a plurality of slide rods 14 and an adaptive layer, the shell 11 is provided with an opening on one side, the adaptive layer is arranged in the shell 11 away from the opening, the plurality of adaptive blocks 12 are slidably arranged in the shell 11, one end of the adaptive block 12 protrudes out of the opening of the shell 11, the plurality of slide rods 14 are arranged in the shell 11 from top to bottom, the horizontal slide groove 13 is arranged on the adaptive block 12, and the slide rod 14 penetrates through the slide groove 13. The plurality of adaptive blocks 12 can move left and right in the shell 11 relative to the slide rod 14, because the workpiece has different shapes, the displacement of each adaptive block 12 is not consistent, which can be as close as possible to the surface of the workpiece to achieve the purpose of profiling, and the adaptive layer can adjust the displacement of each adaptive block 12 to provide support for each adaptive block 12.

[0027] In some possible embodiments, the adaptive layer is filled with a plurality of steel balls 15, when the adaptive block 12 is close to the surface of the workpiece, if the surface of the workpiece is irregular, the plurality of steel balls 15 will be extruded and move in the adaptive layer, so as to change the shape of the adaptive layer, at this time, the plurality of adaptive blocks 12 are in active state to match the irregular surface of the workpiece.

[0028] In some possible embodiments, the slide rod 14 is a flat plate structure, the horizontal width of the slide rod 14 is greater than the vertical width, so as to avoid the inclination of the adaptive block 12 when moving relative to the slide rod 14, which leads to the weakening of clamping.
