Abstract

A CNC spiral bevel gear tooth top chamfering machine includes: a fuselage and an electric control cabinet, a column set on the fuselage, a turning table base set on the machine body, and a turning working table installed on the turning workbench base. There are horizontal movement mechanism and vertical movement mechanism on the column. The vertical movement mechanism is set on the column through the horizontal movement mechanism. The vertical movement mechanism is equipped with a grinding head mechanism for chamfering the spiral bevel gear. A main shaft for installing the gear to be processed is installed on the turning table at a position corresponding to the grinding head mechanism; the grinding head mechanism support has a plane support for connecting to the vertical slide plate and is located on the front side of the plane support and integrally formed with the plane support The arc-shaped bracket used to fix the grinding head mechanism, wherein the inner peripheral surface of the arc-shaped bracket has a convex structure. The invention solves the technical problem that the tooth top chamfering of the spiral bevel gear can only be applied manually. The design structure of this machine tool is reasonable, the work is reliable, the chamfering precision is high, the effect is good, and the efficiency is high.

Description

technical field

[0001] The invention relates to a gear processing machine tool. In particular, it relates to a numerical control spiral bevel gear addendum chamfering machine with accurate processing, high precision and high efficiency. Background technique

[0002] The spiral bevel gear is the gear used for the main transmission of the car, which drives the wheel to rotate through the planetary mechanism. To make a spiral bevel gear, the first step is to make a blank, rough machining and finishing machining, and then heat treatment. After heat treatment, the edge of the gear is deformed, such as figure 1 As shown, the corners 50, 49 of the gear are deformed. Moreover, there are also processing errors in the processing of spiral bevel gears. If they are not processed and used directly for automobile assembly, the deformation of the edges will inevitably increase the noise when the automobile is running.

[0003] In order to ensure that there is no error in the edge positi...
