An assembled grinding tool for grinding a circular plane with a boss

Abstract

The invention discloses an assembled grinding tool for grinding an annular plane with a boss. The assembled grinding tool comprises a base plate, ruby grinding blocks and protective gaskets, wherein the eight trapezoidal grinding blocks define a circular ring and are bonded on the base plate; and the protective gaskets are bonded on the trapezoidal top surfaces on the inner sides of the ruby grinding blocks, so that the grinding tool for grinding the annular plane with the boss is formed. The grinding tool has the advantages that the ruby grinding blocks are fine and hard in texture, so that after the annular plane, with the boss, on a part is processed through the grinding tool, the flatness quality and roughness quality of the plane are greatly improved; abrasive sand is further arranged on the surface, so that the requirement, of aerospace products, on high cleanliness of parts can be completely met; the grinding tool is further applicable to parts which adopt metal materials with relatively low hardness and hardly can be processed by grinding machines; and the grinding tool can be freely assembled and can be flexibly applied to processing of other parts.

Description

technical field [0001] The invention relates to an assembled grinding tool for grinding a plane, in particular to an assembled grinding tool for grinding an annular plane with a boss. Background technique [0002] In the field of mechanical processing, it is often necessary to perform extremely precise processing on important planes on some key parts. These important planes are often difficult to obtain ideal processing accuracy due to structural or material reasons. For example, in aerospace products, the reference surface of bearing seat with boss, the mounting surface of optical lens barrel, the bonding surface of pure copper conductive block, etc., these surfaces have extremely high requirements for their flatness, roughness and cleanliness. Traditional processing It is difficult to meet the above requirements at the same time. Contents of the invention [0003] In view of the various defects of the traditional processing method, the object of the present invention is...
