Further, the stopper is rectangular, and the parallelism tolerance of the two stoppers is not greater than 0.1mm.

Further, the inclination angle of the upper end surface of the wedge block relative to the bottom plate is 8-12°.

Further, a groove is provided on the side of the chute in contact with the support block, and the support block is embedded in the groove.

Further, the surface roughness of the upper end surface of the wedge block and the lower end surface of the support block is Ra0.8.

Further, the adjusting screw is a fine pitch screw.

Further, the surface roughness of the contact surface of the support block with the sliding groove is Ra0.8.

Further, the surface roughness of the contact surface of the chute with the support block is Ra0.8.

The beneficial effect of the utility model is that: through the implementation of the utility model, the height of the supported parts can be adjusted steplessly, and the corresponding adjustment can be made according to the actual required height of the parts until the parts are adjusted to the required height At the same time, through the application of the adjustable support, the labor intensity of operators can be greatly reduced, the efficiency of clamping and alignment of parts can be greatly improved, and it can be popularized and applied in the clamping and alignment of various large parts.
