Technical Field
[0001] The utility model relates to the technical field of end cover processing, in particular to a polishing device for end cover processing. Background Art
[0002] The end cover is the closed part of the engine, installed on the top or bottom of the engine. It is usually made of metal material to protect the inside of the engine from contamination and damage by external substances. When producing the engine end cover, it is necessary to use polishing equipment for polishing, and then coat the surface of the end cover, one to increase the aesthetics of the engine end cover, and the other to further improve the service life of the end cover.
[0003] However, the end cover is generally a hollow cone-shaped structure. When the end face is ground and polished, radial force will be continuously applied, which can easily cause the end cover surface to be concave or even cracked. Moreover, as the end cover material is made of metal material, a large amount of waste chips will be thrown out during the grinding process, polluting the working environment.
[0004] Therefore, in view of the situation that the above-mentioned end cover is easily deformed inward and splashed with waste chips due to the radial extrusion pressure of the polishing machine during polishing, a grinding and polishing device can be designed to support the cavity of the engine end cover, and cooperate with a protective structure surrounding it to prevent the end cover from being deformed inward due to the force, and prevent waste chips from being splashed outward.
