Axle housing accessory welding tooling fixture

Abstract

The invention discloses an axle housing accessory welding tooling fixture. The fixture comprises a platform, an axle housing positioning mechanism and a welded part positioning mechanism; the axle housing positioning mechanism comprises horizontal positioning mechanisms which are arranged on both ends of the platform and a vertical positioning mechanism which is arranged between the two horizontal positioning mechanisms; the welded part positioning mechanism comprises a bottom welded part positioning mechanism and a vertically welded part positioning mechanism; the bottom welded part positioning mechanism comprises a support base and a self-centering positioning mechanisms which are arranged on both sides of the support base; the vertically welded part positioning mechanism comprises a part fixing mechanism and a regulating mechanism. According to the axle housing accessory welding tooling fixture, a plurality of accessories can be clamped and positioned simultaneously, so that the problems that the efficiency is low, the workload is heavy and errors are easily produced when the accessories are respectively positioned are solved. The axle housing accessory welding tooling fixture has the advantages that positioning is accurate, the workload of a worker is reduced, the production efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of tooling fixtures, and in particular relates to a welding tooling fixture for axle housing accessories. Background technique [0002] The car drive axle housing is one of the important parts of the car, which supports the load of the car and transmits the load to the wheels. The traction force, braking force, lateral force and vertical force acting on the driving wheels are also transmitted to the suspension or chassis through the axle housing. Therefore, the axle housing is both a load-bearing part and a force-transmitting part, and at the same time it is also the carrier and shell of the final reducer, differential and drive wheel transmission. The left / right cam frame, upper thrust rod, spring side pin, induction valve frame, air chamber bracket and other accessories need to be welded on the axle housing. Now each accessory is welded with a separate tooling fixture for positioning, so that the axle hou...

AI Technical Summary

Problems solved by technology

The left / right cam frame, upper thrust rod, spring side pin, induction valve frame, air chamber bracket and other accessories need to be welded on the axle housing. Now each accessory is welded with a separate tooling fixture for positioning, so that the axle housing needs to be fixed each time. Positioning, heavy workload, low efficiency, and a large number of fixtures involved, have space requirements for the production workshop

Moreover, the shape of the drive axle is irregular, and positioning is difficult during welding, which is prone to errors. If the processing error is too large, the whole vehicle will not be able to move.
