A shaft head positioning fixture for semi-floating rear axle welding

Abstract

The invention discloses a semi-floating shaft head positioning fixture for rear axle welding, which includes a rotating shaft, a positioning shaft pin and a pressure head, the rotating shaft is installed in the rotating shaft bracket, and the upper end of the rotating shaft is connected with a positioning shaft pin through a positioning pin , the rotating shaft is also connected with the axial adjustment block through the positioning pin, the axial position of the rotating shaft is determined by the axial adjustment block, the two ends of the positioning shaft pin are equipped with cylinder-controlled pressure heads, and the workpiece is positioned by the positioning shaft pin, and Cooperate with the indenter to compress the workpiece; a tapered roller bearing that drives the rotating shaft to rotate is arranged in the rotating shaft bracket; a rotating shaft locking block is arranged in the middle of the rotating shaft bracket, and the rotating shaft passes through the rotating shaft bracket and the rotating shaft locking block. The scale plate of the slot hole; according to different types of rear axles, the fixture can be fixed to the working base plate at the corresponding position through the right-angle plate and then used. It is easy to adjust, strong in versatility, low in cost, and fast in replacement time.

Description

technical field [0001] The invention relates to the technical field of semi-floating rear axles of automobiles, in particular to a shaft head positioning fixture for welding semi-floating rear axles. Background technique [0002] The rear axle is all the force transmission connection between the car body and the wheels, but due to the size of the connection with the car body, the load, the size of the transmission moment, the height from the ground and the arrangement of the tires, etc., the variety and size of the rear axle will be different. At present, the emergence of differentiated complete vehicles in the market has led to the situation of multi-variety and small-batch rear axles. Especially for the semi-floating rear axle, the angles of the shaft heads on both sides relative to the axis of the axle housing change a lot. [0003] Most of the existing semi-floating rear axle welding tooling is made fixed, so when the angle of the shaft head of the product changes, the ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing semi-floating rear axle welding tooling is made fixed. When the angle of the product shaft head changes, the original tooling cannot be used and a new tooling is required.

The development cycle of new tooling is long, the cost is high, and the replacement of fixtures takes a long time; the development cycle of the rear axle cannot keep up with the development cycle of the whole vehicle, the cost is high, the production efficiency is low, and it cannot adapt to market changes and takes a long time and low efficiency. Only random inspection, not full inspection
