Abstract

The invention discloses a machining method of a tension bush clamp for a shifting fork groove of an automobile gear sleeve. The machining method includes a step of sequentially connecting a front connecting plate, a connecting seat and a positioning seat and a step of machining an elastic tension bush and a pull rod, wherein the step of machining the elastic tension bush includes feeding, machining by a machine tool, quenching, rough machining of a grinding machine, tempering, finish machining of the grinding machine, wire-electrode cutting low-speed wire cutting and inspection. The invention aims to provide the machining method of the tension bush clamp for the shifting fork groove of the automobile gear sleeve and solves the problem that a gear sleeve and the tension bush clamp move relatively when an existing tension bush clamp is used for clamping the automobile gear sleeve to machine the shifting fork groove.

Description

technical field [0001] The invention relates to a processing method of a tooling fixture, in particular to a processing method of an expanding sleeve clamp used for a shift fork groove of an automobile gear sleeve. Background technique [0002] Automobile synchronizer shifting not only has the advantages of light shifting, avoiding impact, eliminating noise, and prolonging the life of gears, but also enables rapid shifting and improves the power, economy and safety of the car. Therefore, modern cars, especially Almost all the shifting mechanisms of cars use this device. The automobile synchronizer is mainly composed of gear sleeve, gear hub, synchronous lock ring, etc. It is characterized by relying on friction to achieve synchronization. The synchronizer gear sleeve has a shift fork groove. When the automobile synchronizer gear sleeve is working, it needs to be connected by a shift fork, so that the inverted bevel teeth of the synchronizer gear sleeve mesh with the teeth o...
