Description

Technical Field

[0001] The utility model belongs to the technical field of the processing of cylinder head castings, and more specifically, particularly relates to a grinding device for cylinder head castings. Background Art

[0002] The function of the cylinder head is to seal the cylinder, jointly form a combustion space with the piston, and bear the action of high-temperature and high-pressure combustion gas. The cylinder head bears the gas force and the mechanical load caused by tightening the cylinder bolts. At the same time, it also bears a very high thermal load due to contact with high-temperature combustion gas.

[0003] The existing Chinese patent application number is: CN202220814936.8, which discloses a grinding device for cylinder head castings. This solution provides the advantages of simultaneously grinding both sides of the cylinder head casting during use, without manual flipping, and improving the grinding efficiency. However, when the above technical solution is actually used, it can only place a cylinder head smaller than the diameter of the grinding disc. When grinding a cylinder head with a length exceeding the grinding disc, it is not only difficult to assemble, but also cannot efficiently grind the cylinder head, resulting in a low grinding efficiency. Therefore, in view of this, the existing structure and deficiencies are studied and improved to provide a grinding device for cylinder head castings, with the expectation of achieving a more practical value.
