Pressure maintaining fixture of axle housing automation line

Abstract

The invention discloses a pressure maintaining fixture of an axle housing automation line. The pressure maintaining fixture comprises a fixture body and a clamping device, wherein the fixture body is in a plate structure, and is provided with a hydraulic oil runner inside; the clamping device comprises two V-shaped clamping bases arranged above the fixture body, and a positioning clamper arranged above the fixture body and positioned between the two V-shaped clamping bases; each V-shaped clamping base comprises a static clamping column and a movable clamping column; a first thin oil pressure cylinder and a tension arm driven by the first thin oil pressure cylinder are vertically arranged at the upper end of each movable clamping column; clamping rods for clamping the two ends of an axle housing and second thin oil pressure cylinders for driving the clamping rods are arranged at the outer side of each movable clamping column; and the positioning clampers comprise static positioning blocks and movable positioning blocks. The pressure maintaining fixture of the axle housing automation line can guarantee the clamping force of the fixture to reach the positioning requirement so as to reliably fix the axle housing.

Description

technical field [0001] The invention relates to a pressure-maintaining fixture for an automatic line of an axle housing, and belongs to the technical field of fixtures for processing vehicle parts. Background technique [0002] In the existing technology, the clamps of the axle housing automatic line are all manual clamps, which are manually positioned and clamped by the operator, which not only has high labor intensity and low clamping efficiency of the axle housing, but also is greatly affected by human factors, and the positioning error cannot be estimated. The positioning quality of shells cannot be guaranteed. Few companies use hydraulic clamps, and the positioning accuracy of the clamps can be guaranteed, but the oil pipe of the automatic line is too long, not only the pressure loss is large, but also the possibility of hydraulic oil leakage is greatly increased, which will easily cause the clamping force of the clamps to fail to meet the positioning requirements, whic...

Problems solved by technology

[0002] In the existing technology, the clamps of the axle housing automatic line are all manual clamps, which are manually positioned and clamped by the operator, which not only has high labor intensity and low clamping efficiency of the axle housing, but also is greatly affected by human factors, and the positioning error cannot be estimated. Shell positioning quality cannot be guaranteed

A few enterprises use hydraulic clamps, which can ensure the positioning accuracy of the clamps. However, the oil pipe of the automatic line is too long, not only the pressure loss is large, but also the possibility of hydraulic oil leakage is greatly increased, which will easily cause the clamping force of the clamps to fail to meet the positioning requirements.
