Differential case vehicle inner spherical surface two-side pressing clamp

Abstract

The invention provides a differential case vehicle inner spherical surface two-side pressing clamp. The differential case vehicle inner spherical surface two-side pressing clamp comprises a clamp body, wherein a connecting flange portion is arranged at the rear end of the clamp body; bosses are symmetrically arranged at the front end of the clamp body, and elastic sleeve clamping mechanisms are symmetrically arranged on the bosses. When the clamp is in use, the clamp body is connected to a lathe spindle, tightening nuts are connected with a pull rod in the lathe spindle, and the tightening nuts move to drive the two elastic sleeve clamping mechanisms to simultaneously carry out centering and clamping through a first swing arm and a second swing arm. A rotation-preventing positioning block and a balance weight are further arranged on the clamp body. According to the differential case vehicle inner spherical surface two-side pressing clamp, the clamp body is of an integrated structure, synchronous swing arms on the two sides carry out self-centering clamping and pressing, and disc springs at the two ends carry out pre-adjustment pressing; due to the fact that the balance weight is arranged, the phenomenon that centrifugal force is overlarge can be avoided, dynamic balance is achieved, and it is ensured that clamping is quick, and positioning is accurate.

Description

technical field [0001] The invention relates to an interior spherical surface clamp of a differential case of a car, in particular to a clamp for pressing both sides of a differential case ball. Background technique [0002] The car differential housing is the framework for the connection and support of the differential. The outer circles at both ends are the connecting surfaces of the inner holes of the supporting bearings of the housing, and the large outer circle in the middle is the fixed outer circle of the ring gear. During the movement of the differential, the two pairs of bottom spherical bevel gears realize the differential movement according to the trajectory of the wheel movement. [0003] The size and position tolerance requirements of the spherical surface are high. During the processing, the spherical surface must be processed by rough turning and fine turning respectively. Fixture schemes of other manufacturers are as follows: 1. Fix the outer circle position...

AI Technical Summary

Problems solved by technology

During the processing process, the fixture cannot realize automatic positioning and clamping, and the manual labor intensity of employees is high, and the clamping efficiency is low

[0004] Since the spherical center and the center of gravity of the poor shell do not coincide, the overall structure of the fixture is larger
