[0030] Working principle: First, the high-precision parts to be positioned are placed on the cushion plate 201, which is above the positioning plate 2, which is set inside the workbench 1. By controlling the extension and retraction of the hydraulic rod 202, the height of the cushion plate 201 can be adjusted, and the vertical position of the part can be changed to meet different processing needs, laying the foundation for subsequent accurate positioning. In the horizontal direction, the limiting group 3 above the cushion plate 201 plays a key role. The limiting group 3 includes two clamping plates 301. When the hydraulic rod 202 pushes the positioning plate 2 up and down, the clamping plates 301 will move towards the part and preliminarily clamp it horizontally, limiting its large-scale movement in the horizontal plane. To achieve more accurate horizontal positioning, the moving group 4 and the linkage group 5 inside the clamping plate 301 work together. The inside of the two clamping plates 301 is provided with a groove one 307, and the moving group 4 is embedded in it and can move.

When the moving group 4 moves, it will drive the linkage group 5 to slide in the groove two 402. The linkage group 5 is composed of a detachable linkage plate 501, and the inside of the linkage plate 501 is provided with a groove three 502, which is movably connected with the protrusion 601 outside the contact block 6. When the linkage group 5 moves, it can adjust the position and angle of the contact block 6 according to the shape and position of the part. The inside of the contact block 6 is made of rubber, which can increase the friction force when contacting the part to prevent the part from slipping, and can also buffer the contact force to avoid damaging the surface of the part. In addition, the two clamping plates 301 are provided with support blocks 302 at the bottom. One support block 302 is fixed on the cushion plate 201, and the other is movably connected. The two ends of the movable support block 302 penetrate through the screw rod 303, which is driven by the motor 304 and is in threaded connection with the support block 302. The auxiliary rod 305 outside the support block 302 and the slider 306-slip groove 203 structure ensure the stability and linearity of the movement, so that the operator can accurately control the distance between the clamping plates 301 to complete the clamping and loosening operation of the part.
