Welding device for automobile rear-axle housing flange ring

Abstract

The invention provides a welding device for an automobile rear-axle housing flange ring. The welding device is provided with a work table and a flange ring locating mechanism. A supporting sleeve is arranged in an installation hole in the work table. The flange ring locating mechanism is supported by the supporting sleeve and provided with an internally-hinged plate, a sliding rod, a compression spring, an externally-hinged plate and a first air cylinder. The lower portion of the externally-hinged plate is inserted into the supporting sleeve. Claws uniformly distributed are hinged to the peripheral face of the externally-hinged plate. The middle of the sliding rod is arranged in a center hole of the externally-hinged plate. The portion, located on the sliding rod, in the externally-hinged plate is provided with the compression spring. The internally-hinged plate is connected to the upper portion of the sliding rod. Connecting rods corresponding to the claws in a one-to-one mode are hinged to the internally-hinged plate. The ends of the connecting rods are hinged to the middle portions of the corresponding claws. A hanging frame is arranged below a platen. The first air cylinder is fixed on the hanging frame. A piston rod of the first air cylinder extends upwards and is connected with the sliding rod. The welding device is simple in structure and convenient to operate, improves the location precision and the production efficiency, and is particularly suitable for being used in an automation production line.

Description

technical field [0001] The invention relates to a welding device for flange rings of automobile rear axle housings. Background technique [0002] figure 1 and figure 2 Shown is a schematic diagram of an automobile rear axle housing (automobile drive axle housing). The rear axle housing of an automobile is one of the main load-bearing components on the automobile. Its main functions are: to support and protect the final drive, differential and axle shafts, etc., to fix the axial relative positions of the left and right driving wheels; together with the driven axle Support the frame and the mass of each assembly on it. When the car is running, it bears the road surface reaction force and moment transmitted from the wheels and transmits it to the frame through the suspension. The automobile rear axle housing should have sufficient strength and rigidity and low mass, and it should be easy to disassemble and adjust the final drive. The integral vehicle rear axle is widely u...

AI Technical Summary

Problems solved by technology

The current production methods mainly include manual positioning welding and automatic welding, but both encounter the problem of rapid positioning between the flange ring and the rear axle housing, which affects the production efficiency and product quality
