PCD spiral type reamer

Abstract

The invention discloses a PCD spiral type reamer. The PCD spiral type reamer comprises a reamer body and a reamer handle, wherein a positioning structure is arranged on the top of the reamer body. The positioning structure comprises two positioning protrusions which are in a cone shape and distributed at the two ends of the top face of the reamer body. A clamping component is arranged on the outer portion of the tail end of the reamer handle, wherein the reamer handle and the clamping component are of an integral structure, the clamping component is of a circular truncated cone structure, and the ratio of the height H1 of the front end of the clamping component to the height H2 of the tail end of the clamping component is 1.5:1. Arc-shaped grooves are symmetrically formed in the two sides of the clamping component. With the central axial surface of the reamer handle as the reference plane, the front end vertex angle alpha of the clamping component is 48 degrees; due to the fact that the special positioning structure is arranged on the top of the reamer body, the reamer body is accurately positioned in the turning process and is not prone to deflection; the clamping component is arranged on the reamer handle, and therefore a tool can be effectively clamped, losses are reduced for enterprises, production cost is reduced for enterprises, and production efficiency is greatly improved for enterprises.

Description

technical field [0001] The invention relates to a PCD spiral reamer, which belongs to the technical field of metal cutting tools. Background technique [0002] At present, cutting tools in the machining industry are developing in the direction of high precision, high speed and high efficiency. Polycrystalline diamond (PCD for short) hole machining tools are one of the tools with high utilization rate at present. It is difficult to locate the cutting tool during machining. , It is prone to deviation, which will affect the production efficiency of enterprises. And because the drilling tool needs to rotate at high speed during the drilling process, it needs to be tightly clamped with the fixture. At present, most of the reamer handles on the market are cylindrical. When drilling at high speed, slipping often occurs, and the fixture does not It is easy to clamp, and there is even the possibility of falling from the clamp, creating a safety hazard. Therefore, the development of...
