Description

Technical Field

[0001] The utility model relates to a grinding wheel assembly, in particular to a grinding wheel assembly which is convenient to disassemble and belongs to the technical field of grinding wheels. Background Art

[0002] Grinding wheel, also known as bonded abrasive tool, is a bonded abrasive tool with a certain strength that is formed by bonding ordinary abrasive into a certain shape (mostly round with a through hole in the center). It is generally composed of abrasive, bonding agent and pores, which are often called the three elements of bonded abrasive tools. According to the different classifications of bonding agents, common ones include ceramic (bond) grinding wheels, resin (bond) grinding wheels, and rubber (bond) grinding wheels. Grinding wheel is the most widely used and widely used abrasive tool. It rotates at high speed when used, and can be used for rough grinding, semi-finishing grinding and fine grinding of the outer circle, inner circle, plane and various surfaces of metal or non-metal workpieces, as well as grooving and cutting. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, particle size, bonding agent, hardness, structure, shape and size.

[0003] The patent document with the prior art publication number CN218341837U provides a grinding wheel that is easy to replace, including a grinding wheel main body and an assembly component, wherein the grinding wheel main body adopts a circular ring structure with an assembly hole arranged in the middle, and the assembly component is arranged in the middle of the grinding wheel main body to assist in fixing the grinding wheel main body with the grinding machine, and the assembly component comprises a sub-component and a mother component, and the sub-component and the mother component are respectively engaged on both sides of the grinding wheel main body, and a detachable connection is adopted between the sub-component and the mother component, so that the assembly component can be removed from the grinding wheel main body. The utility model is suitable for a grinding wheel. After the grinding wheel is damaged during use, the sub-component and the mother component in the assembly component can be disassembled and removed from the grinding wheel main body. At this time, a new grinding wheel main body can be replaced, and the sub-component and the mother component can be assembled to the new grinding wheel main body, and then the grinding wheel can be assembled to the grinding machine, that is, the assembly of the grinding wheel main body is completed, the operation is convenient and quick, and this can reduce the use cost of the grinding wheel.

[0004] However, during the use of the existing grinding wheel assembly, since the grinding wheel is mainly composed of a wheel body and a mounting part, when the grinding wheel produces a lot of wear, the grinding wheel needs to be replaced. Although the wheel body and the mounting part combination can be disassembled for replacement, when the wheel body and the mounting part are disassembled, they are fixed and installed with a sampling bolt structure, which makes it inconvenient to separate the wheel body and the mounting part, resulting in cumbersome disassembly steps of the grinding wheel assembly. For this reason, we propose a grinding wheel assembly that is easy to disassemble. Utility Model Content
