PCD reamer for enlarging diameter hole

Abstract

The invention discloses a PCD reamer for enlarging a diameter hole. The reamer comprises a base body, the base body is composed of a disc, a connecting rod and a joint, a flange adjusting structure iscut in the disc, one side of the disc is fixedly connected with a connecting rod, the side, away from the disc, of the connecting rod is fixedly connected with the joint, multiple blade grooves are cut in the outer side of the joint, and PCD blades are welded in the blade grooves. The PCD reamer has the beneficial effects that the structure is compact, operation is easy and rapid, production is convenient, practicability is high, an inner hole cooling structure is adopted for cooling, the steel base body is adopted in the device body, the equipment strength is improved, meanwhile, a chip removal groove for chip removal is formed in the reamer body, through a particular framework, the machining product tolerance reaches 6 levels, the surface roughness of the machined product is within Ra0.8, the cylindricity of the machined product is within 0.01, and in addition, the machining efficiency of the reamer is four times or above of a traditional fine adjustment boring cutter type guide strip tool.

Description

technical field [0001] The invention relates to a PCD reamer, in particular to a PCD reamer with enlarged diameter holes. Background technique [0002] In the existing life, in the field of mechanical processing, the reamer is used to improve the precision of the machined hole and reduce the surface roughness. The existing reamer is generally made of overall alloy of the cutter head and handle. The existing reamer The surface roughness of the processed product is relatively large, which makes the processed product not fine enough. At the same time, the processing accuracy of the cylindricity is low, which greatly reduces the working efficiency of the traditional reamer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a PCD reamer with enlarged diameter holes for the deficiencies of the prior art. [0004] In order to achieve the above object, the measures taken by the present invention: [0005] A PCD reamer wi...
