AI Technical Summary

Technical Problem

The existing half-shaft gear stop machining process is prone to omissions, resulting in the stop position not being detected, which affects product quality and assembly. Furthermore, the existing fixture structure lacks effective anti-leakage detection measures, increasing inspection costs and time.

Method used

A leak-proof clamp structure was designed, including a clamp base, a limiting component, and a reinforcing component. The limiting component consists of a limiting support ring, a gear limiting groove, a receiving limiting groove, and a stop limiting boss. The clamp is connected by the limiting support ring, the fixing component, the miniature cylinder, and the connecting component, which includes the miniature cylinder, the connecting block, the positioning fixing groove, and so on.

Benefits of technology

This enables 100% inspection of the stop position of the half-shaft gear during the machining process, avoiding missed machining, reducing inspection costs and time, and improving product quality and assembly efficiency.

Abstract

This utility model discloses an integrated fixture structure for leak-proof machining of the stop edge of a half-shaft gear, relating to the field of half-shaft gear machining technology. It includes a fixture base and a limiting component. The fixture base is an integrated structure, and the limiting component is disposed on the surface of the fixture base. The limiting component includes a limiting support ring, a gear limiting groove, a receiving limiting groove, and a stop edge limiting boss. The limiting support ring is disposed on the upper side of the fixture base, and the fixture base and the limiting support ring are a tightly connected integrated structure. This integrated fixture structure for leak-proof machining of the stop edge of a half-shaft gear, through the limiting component, allows the device to perform 100% inspection of the stop edge position of the half-shaft gear during machining and clamping, eliminating the need for additional labor for inspection, saving time and effort, and reducing inspection costs. The reinforcing component further reinforces the upper side of the half-shaft gear, further preventing the half-shaft gear from shaking or shifting during finishing.
