Deburring mechanism suitable for combustion chamber surface of engine cylinder cover

The utility model provides a deburring mechanism suitable for a combustion chamber surface of an engine cylinder cover, and belongs to the technical field of deburring of engine cylinder covers. The problem that when a mechanical grinding and deburring mechanism conducts grinding, a brush is prone to shaking when moving on an engine cylinder cover, and therefore the deburring effect is not ideal is solved. The deburring device comprises a main body, a deburring assembly, an air cylinder and a plurality of supports, the supports are arranged at the bottom of the main body, a first linear guide rail is arranged on the top end face of the main body, and a second linear guide rail and a third linear guide rail are arranged on the end face of one side of the main body; the first linear guide rail, the second linear guide rail and the third linear guide rail are arranged in the length direction of the main body, the deburring assembly is slidably connected to the main body through the first linear guide rail, the s
