Abstract

The invention relates to a PCD adjustable reamer for machining a cylinder body water hole blanking cap hole. The reamer comprises a reamer holder and a reamer bit. The reamer holder and the reamer bit are of an integrated structure. The reamer bit is provided with a finish reaming blade and a damage blade. The finish reaming blade is fixed to the reamer bit. The damage blade is fixed to the reamer bit in an adjustable manner through screws. The finish reaming blade and the damage blade are combined, the roughness of the hole wall can be effectively controlled, and a product is more convenient to use and more tightly arranged in the assembling process.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a PCD adjustable reamer for processing cylinder water hole plugging and cover holes. Background technique [0002] The traditional reamer used to process the water hole plugging hole of the cylinder body cannot adjust the size of the broken teeth during processing, and the roughness of processing cannot be adjusted in time, and the processing form is single. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a PCD adjustable reamer for processing the plugging hole of the water hole of the cylinder body, which combines fine reaming and destruction, can effectively control the roughness of the hole wall, and makes the product more convenient in the assembly process and tight. [0004] In order to solve the problems of the technologies described above, the technical solution of the present invention is: [0...
