Grinding wheel with split dovetail groove structure

Abstract

The invention discloses a grinding wheel with a split dovetail groove structure. The grinding wheel comprises an annular metal base body (1) and a grinding wheel grinding layer fixed on the peripheral surface of the metal base body (1), wherein the grinding wheel grinding layer is formed by combining a plurality of grinding wheel grinding blocks (2); dovetail grooves (3) are formed in the peripheral surface of the metal base body (1); a dovetail bugle (4) is arranged at the bottom of each grinding wheel grinding block (2); the dovetail bugles (4) of the grinding wheel grinding blocks (2) are embedded into the dovetail grooves (3) of the metal base body (1); the grinding wheel grinding blocks (2) are fixed to the metal base body (1); gaps (5) are formed in the embedded parts of the dovetail bugles (4) and the dovetail grooves (3). According to the grinding wheel, the split dovetail groove structure is adopted, so that materials are saved and the use cost is reduced; the grinding wheel has the characteristics that the production investment is small, the cost is low, the manufacturing process is easy to control, the scrap rate is low and the safety is good.

Description

technical field [0001] The invention relates to a grinding wheel, in particular to a dovetail groove split grinding wheel, which belongs to the technical field of grinding tools. Background technique [0002] At present, the grinding wheel used is mainly of integral structure, that is, the entire grinding wheel is composed of abrasive materials. This integral grinding wheel cannot be used after being worn to a certain extent. The remaining grinding wheel can only be discarded, and the entire grinding wheel needs to be replaced, resulting in material waste. , The utilization rate is low, and the use cost is increased. And when grinding at high speed, it is easy to be damaged by force, which is not safe. During the production process, due to reasons such as uneven molding and difficult control of sintering, the quality of the produced grinding wheels varies and the rejection rate is high. This is especially true for grinding wheels with larger diameters, such as grinding whe...

[0002] At present, the grinding wheel used is mainly of integral structure, that is, the entire grinding wheel is composed of abrasive materials. This integral grinding wheel cannot be used after being worn to a certain extent. The remaining grinding wheel can only be discarded, and the entire grinding wheel needs to be replaced, resulting in material waste. , low utilization rate, increased use cost

And when grinding at high speed, it is easy to be damaged by force, which is not safe

During the production process, due to uneven molding and difficult control of sintering, the quality of the produced grinding wheels is different, and the scrap rate is high.

This is especially true for grinding wheels with larger diameters, such as grinding wheels over 500mm, and the integral grinding wheel also requires the investment of large-scale production equipment, which has the problems of large production investment and high production cost.
