Machining tool

Abstract

The invention discloses a machining tool. The machining tool comprises a first knife handle and a second knife handle, wherein the upper surface of the second knife handle is provided with a deep groove, the bottom wall of the deep groove is fixedly connected with a first rolling bearing, the inner wall of the first rolling bearing is fixedly connected with a threaded cylinder, the inner wall of the threaded cylinder is in threaded connection with a threaded rod, the top end of the threaded rod is fixedly connected with the lower surface of the first knife handle, the outer wall of the threaded cylinder is fixedly sleeved with a first bevel wheel, the groove wall of the deep groove is provided with a circular through hole, the hole wall of the circular through hole is fixedly provided witha second rolling bearing, and the inner wall of the second rolling bearing is fixedly connected with a telescopic rod. The machining tool has the advantages that the situation that the personal safety of workers is harmed when a grinding machine is close to the hands during tool polishing can be avoided by changing the length of the tool, the safety of tool polishing is improved, the longer length provides convenience for controlling polishing of the tool, the polishing time is reduced, the precision of tool polishing is improved, and the efficiency of machining is improved.

Description

technical field [0001] The invention relates to the technical field of cutters, in particular to a processing cutter. Background technique [0002] Knives are tools used for cutting in mechanical manufacturing, also known as cutting tools. Most of the knives are machine-used, but there are also hand-used ones. Since the knives used in mechanical manufacturing are basically used for cutting metal materials, so The term "knife" is generally understood as a metal cutting tool. After a period of use, the tool needs to be polished to facilitate better processing of metal materials. [0003] Most of the existing knives are polished manually on the grinding machine, but the handle of the general knives is relatively short. When the staff is holding the grinding machine, the hand is close to the grinding machine, and the grinding machine is easy to hurt the hand, endangering the personal safety of the staff. , the safety is low, and the grinding precision is low, and it takes a lon...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the tool handles of the knives in the prior art are relatively short. When the staff holds the grinding machine, the hand is relatively close to the grinding machine, and the grinding machine is easy to hurt the hand, endangering the personal safety of the staff, and the safety is low. , and the grinding accuracy is low, it takes a long time, which affects the efficiency of machining, and a processing tool is proposed
