High-precision hob rake angle grinder

Abstract

The invention discloses a high-precision hob rake angle grinder. The high-precision hob rake angle grinder includes a main body, and a base and a lathe body which are arranged on the main body; the lathe body is provided with a control mechanism, a hob cutter grinding mechanism, a first sliding pair, a second sliding pair and a workbench surface, and the control mechanism is electrically connectedwith the hob cutter grinding mechanism, the first sliding pair and the second sliding pair; the control mechanism includes a control box disposed at one end of the lathe body, a liquid crystal display screen disposed on the control box, and an operation panel disposed below the liquid crystal display screen; the hob cutter grinding mechanism includes an index head disposed inside the lathe body,a mandrel connected with the index head, the base, and a stand column disposed on the base; and a grinding motor is disposed on the stand column, and a grinding wheel is disposed on the grinding motor. According to the high-precision hob rake angle grinder, the feed in the vertical direction of the grinding wheel is carried out by a lifting cylinder, so that the problem that existing rake angle grinders are low in machining precision is effectively solved, and the advantages of simple structure, convenient use, and good use effect are achieved.

Description

technical field [0001] The invention relates to the technical field of rake angle grinders, in particular to a high-precision hob rake angle grinder. Background technique [0002] The hob is a gear processing tool whose teeth are arranged in a helical line along a cylinder or a cone. It is used to process cylindrical gears, worm gears and other cylindrical toothed workpieces according to the generation method (see gear processing, gears). According to different uses, hobs are divided into gear hobs, worm gear hobs, non-involute developed hobs and fixed hobs, etc., which are commonly used for processing external meshing spur gears and helical cylindrical gears. During processing, the hob is equivalent to a helical gear with a large helix angle, and the number of teeth is the number of heads of the hob. The workpiece is equivalent to another helical gear, which meshes with each other according to a pair of helical gears and rotates at a fixed speed ratio. , The tooth profile ...

AI Technical Summary

Problems solved by technology

[0003] The current grinding machine has a low degree of automation when processing the hob, and manually feeds the rake angle of the hob, which has the problem of low processing accuracy, resulting in low quality of the hob
