[0006] Furthermore, the positioning and clamping device includes a first telescopic device, and the first telescopic device is provided with four groups. The four groups of the first telescopic devices are symmetrically installed on the upper end of the workbench, and the telescopic end of the first telescopic device is fixedly installed with a V-shaped push plate.

[0007] Furthermore, the central column is used to place the disc to be processed.

[0008] Furthermore, a plurality of groups of second telescopic devices are provided at the bottom of each group of the moving rings, the bottom of the second telescopic devices is fixedly mounted on the bottom of the mounting groove, and the telescopic ends of the second telescopic devices are fixedly mounted on the moving rings.

[0009] Furthermore, the up and down moving distance of the moving ring is the same as the thickness of each group of moving rings.

[0010] Furthermore, the moving strokes and states of the four groups of the first telescopic devices are the same.

[0011] The beneficial effect of the utility model is as follows: by placing the disc to be processed on the central column, and then starting four groups of first telescopic devices at the same time, the first telescopic devices simultaneously push the V-shaped push plates to move, so that the four groups of V-shaped push plates can center and clamp the disc, and then according to the required punching position and the size of the disc, the corresponding second telescopic device is started, so that the second telescopic device drives the corresponding moving ring to move downward, and the bottom reserves a working space for the punching device, which can be suitable for discs of different specifications.
