The structure makes full use of the upper surface and the lower surface of the upper grinding disc, and improves the utilization rate of the grinding disc.

In one embodiment, the first bearing 5 is fixed at the central position of the middle layer, and the central shaft is fixedly connected with the lower layer, the first bearing and the upper layer, and the connection mode can generally adopt an interference fit mode. In order to facilitate the fixing of the lower grinding disc to the frame of the grinding machine, the lower grinding disc is provided with fixing holes 1-3 in its bottom surface, which fixing holes can generally be threaded holes.

In one embodiment, referring to fig. 5, the bottom surface of the second groove is provided with threaded holes 1-21, and the diameter of the threaded holes is smaller than that of the second groove, so that the second groove can limit the descending distance of the protrusion, and can fix the edge of a circular plane type product by using bolts and the threaded holes or fix a clamp by the threaded holes so as to facilitate grinding of the circular plane type product.

In this application, first briquetting and second briquetting can have multiple setting mode, and wherein commonly used has two kinds of modes:

mode 1: referring to fig. 3 and 6, the first pressing body is a circular pressing block, an elastic block 6 is fixed on the lower surface of the edge of the circular pressing block, the elastic block can be a rubber block or a silica gel block, preferably, the rubber block is selected, and the elastic block can play a certain buffering role on a product to be ground in the first groove when the first pressing body is under pressure, so that the product to be ground is prevented from being damaged.

Mode 2: referring to fig. 4 and 6, the first pressing body is a bracket, and an elastic block is fixed on the lower surface of the edge of the bracket.

In this application, the second pressing body may also be a circular pressing block or a bracket. In one embodiment, the lower surface of the second press body is provided with a plurality of hemispherical grooves 4-1, which are recesses shaped like half of a ball, so that the position of the ball product between the upper grinding disc and the second press body can be limited by the hemispherical grooves, and the ball product is prevented from being separated from the upper grinding disc during grinding. Elastic block

In this application, the mounting means commonly used of second stand has two kinds:

mode 1, referring to fig. 7, a second bearing 7 is arranged on the second pressing body, the bottom end of the second upright post is connected with the second bearing, and the second bearing is in threaded connection with the first pressing body.
