Transfer trolley for handling automobile rear axle assembly

Abstract

The invention discloses a transfer trolley for handling an automobile rear axle assembly. Side frames are symmetrically arranged on the left and right ends of a base frame, a cantilever is arranged onthe left side of the lower part of the side frame on the right side, a plurality of supporting plates are arranged on the left side of the cantilever front to back, each supporting plate is providedwith a positioning column, the left and right sides of the base frame are each provided with a supporting beam, a plurality of columns are fixed on each supporting beam, a positioning box is arrangedon the top of each column, a positioning box is embedded in each positioning block, swing arms are arranged on the inner sides of the upper ends of the two side frames, a plurality of pressure blocksare arranged at the opposite sides of the suspension ends of the two swing arms front to back, the middle part of the left side of the base frame is provided with a traction frame, the bottom end of the traction frame is fixed on a clamping shaft, and the front and rear ends of the clamping shaft pass through two supports reversely. According to the invention, tension springs provide the elastic force to press the pressure blocks on the bushing of the rear axle assembly, the rear axle assembly is reliably positioned on the transfer trolley by combining positioning devices, and thus the rear axle assembly is effectively prevented from shaking and falling.

Description

technical field [0001] The invention relates to a transfer vehicle used for turning over the rear axle assembly of automobiles. Background technique [0002] The rear axle assembly of a car is generally composed of beams, trailing arms, bushings and spring seats. The trailing arms are arranged symmetrically at both ends of the cross beam. The trailing arms are made of round tubes. One end of the trailing arm is welded to the bushing and the other Welded spring seat. At present, after the rear axle assembly is welded and formed, it still needs to go through processes such as drilling and deburring, heat treatment, and electroplating. These processes are usually carried out in different workshops, so a transfer vehicle must be used for turnover. Although the structure of the existing transfer vehicle is simple, the reliability of the positioning of the rear axle assembly is poor, and the rear axle assembly is prone to shaking during the transfer process, which easily causes s...

AI Technical Summary

Problems solved by technology

At present, the traction device on the transfer vehicle that cooperates with the power head usually has two structures. One is a fixed structure, which is arranged on the side of the transfer vehicle chassis. This structure will increase the lateral size of the transfer vehicle and make the transfer vehicle The space occupied is larger; the other is a flip-type structure, which not only has a complex structure of the traction frame and high production costs, but also needs to be equipped with elastic elements such as torsion springs or tension springs to provide restoring force, and the assembly operation is extremely inconvenient
