Cutter grinding device capable of preventing cutting precision from being affected by uneven cutting edge

Abstract

The invention provides a cutter grinding device capable of preventing cutting precision from being affected by an uneven cutter edge, and relates to the technical field of cutters. The cutter grinding device capable of preventing the cutting precision from being affected by the uneven cutter edge comprises a grinding assembly, a rotating rod is arranged in the grinding assembly, a first lead screw is welded to the bottom of the rotating rod, and the outer wall of the bottom of the first lead screw is in threaded connection with a rack. According to the cutter grinding device capable of preventing the cutting precision from being affected by the uneven cutter edge, the rotating rod is rotated, at the moment, two grinding rollers can be tightly attached to the left side and the right side of the cutter edge of a cutter on the top of a fixing plate, and therefore the effect that the cutter cutting precision is reduced due to the fact that the grinding degrees of the two sides of the cutter edge are different is avoided. A butterfly-shaped rotary knob is rotated, the transmission ratio between a second conical shaft and a first conical shaft can be changed at the moment, the rotating speed of the grinding rollers is further changed, and therefore the effects that the grinding speed is conveniently adjusted according to cutters made of different materials, the working time is saved, and the working efficiency is improved are achieved.

Description

technical field [0001] The invention relates to the technical field of knives, in particular to a knives grinding device that prevents uneven knives from affecting cutting accuracy. Background technique [0002] The tool is a tool used for cutting in mechanical manufacturing. After a long time of use, the tool will be blunted and affect its use. It needs to be re-polished. When the existing tool grinding device is used to grind the edge of the tool, only one side Grinding on one side, the grinding process not only consumes a lot of time, but it is also difficult to ensure that the two sides of the tool edge are polished to the same degree, which will easily lead to unevenness on both sides of the tool, which will affect the cutting accuracy of the later tool, and the grinding structure is relatively fixed. The adjustment of the grinding speed seriously affects the grinding speed. [0003] In order to solve the above problems, we provide a tool grinding device that avoids th...

[0002]The cutting tool is a tool used for cutting in mechanical manufacturing. After a long time of use, the cutting tool will be blunted and affect its use. It needs to be re-grinded. The existing When the advanced tool grinding device grinds the knife edge, it can only grind one side. The grinding process not only consumes a lot of time, but also it is difficult to ensure that the two sides of the knife edge are polished to the same degree, which will easily lead to unevenness on both sides of the knife and affect the later cutting of the knife. accuracy, and the grinding structure is relatively fixed, it is impossible to adjust the grinding speed according to the tools of different materials, which seriously affects the grinding speed

[0003] In order to solve the above problems, we provide a tool grinding device that avoids the unevenness of the knife edge from affecting the cutting accuracy. The advantages of time to speed up productivity
