Abstract

The invention discloses a grinding wheel. The grinding wheel comprises a circular base sheet, wherein the shape of the outer edge of the circular base sheet is circular and the shape of the inner edge of the circular base sheet is noncircular. The grinding wheel is simple in structure and convenient to manufacture; compared with the conventional disc-shaped grinding wheel, the circular grinding wheel provided by the invention greatly saves raw materials during manufacturing, so that cost is reduced; and since a large quantity of grinding wheel materials near a central installing hole of the conventional grinding wheel are not used actually, the grinding wheel provided by the invention has the same service life with the conventional grinding wheel and has lower cost than that of the conventional grinding wheel. The invention further discloses a fixing disc for installing the grinding wheel. The fixing disc comprises a disc body, wherein the installing hole is formed in the center of the disc body; one side of the outer edge of the disc body radially protrudes so as to form a shoulder-shaped lug boss on the disc body; the protruding part of the shoulder-shaped lug boss is a circular base sheet installing part and is matched with the inner edge of the circular base sheet in shape. The fixing disc provided by the invention is simple in structure and convenient to install and detach the grinding wheel.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a grinding wheel sheet and a fixed disc thereof. Background technique [0002] The shape of the existing grinding wheel in the market is a disc with a mounting hole in the center. The pre-use grinding wheel is installed on the power shaft of a cutting machine through its mounting hole, and the outer edge of the grinding wheel is constantly worn during use, so the diameter of the grinding wheel is continuously reduced. When the diameter of the grinding wheel is worn to a certain extent, it must be removed from the power shaft and replaced with a new grinding wheel. The removed grinding wheel is discarded and discarded. The old grinding wheel has a large amount of grinding wheel material. Also cannot be recycled. That is, for the existing grinding wheels in the market, a large amount of grinding wheel material near the center mounting hole is destined to be wasted. ...
