Dedicated PCD composite tool of gear shifting cover

Abstract

The invention discloses a dedicated PCD composite cutter of a gear shifting cover and especially relates to the composite cutter field. A knife rest is included. A top end of the knife rest is connected with a chuck. A tool apron is arranged at a front side position, close to the chuck, of the top of the knife rest. The tool apron is a triangular structure. A blade is installed above the tool apron. A pressing plate is arranged above the blade. Protruding blocks are evenly arranged on an edge of the tool apron, clamping grooves are evenly arranged in positions, corresponding to the outer portions of the protruding blocks, of an edge of a lower surface of the blade, a tool handle is connected to a rear end of the knife rest, clamping blocks are arranged on an inner side of the tool handle at an end portion of the knife rest, and sliding rail grooves are arranged in the tool handle and correspond to outer portions of the clamping blocks. Stability of the blade after installation is improved, then machining quality and machining efficiency are effectively increased in a machining process, the tool handle is convenient to assemble and disassemble in a using process, and wastes caused by direct discarding of an integrated cutter which is damaged are avoided.

Description

Technical field [0001] The present invention relates to the field of composite tools, and more specifically, the present invention relates to a PCD special composite tool for a shift cover. Background technique [0002] As a super-hard tool material, diamond has been used in cutting for hundreds of years. In the development of tools, from the end of the nineteenth century to the middle of the twentieth century, the tool material was mainly represented by high-speed steel; in 1927, Germany first developed hard Alloy tool materials have been widely used; in the 1950s, Sweden and the United States synthesized synthetic diamonds respectively, and cutting tools have entered a period represented by superhard materials. In the 1970s, people used high-pressure synthesis technology. Synthetic polycrystalline diamond (PCD), which solves the problem of scarcity and high price of natural diamond, expands the application range of diamond tools to aviation, aerospace, automobile, electronics, ...

AI Technical Summary

Problems solved by technology

[0003] In the process of processing the shift cover of the car, tool processing is usually used, but when the existing tools for processing the shift cover are actually used, the fixing method of the blade is not good, resulting in low processing efficiency of the shift cover. Low cost and the quality of the processed finished product is poor. At the same time, the existing knives generally have an integrated structure of the tool holder and the handle. After the tool holder is damaged, the handle is also discarded, resulting in waste of resources.
