Description

Technical Field

[0001] The utility model relates to the technical field of a bridge housing welding auxiliary fixing device, in particular to a bridge housing welding tool used for automobile axle processing. Background Art

[0002] The bridge housing of a car axle is the basic component for installing the main reducer, differential, half-axles, wheel hubs and suspension. Its main function is to support and protect the main reducer, differential and half-axles. At the same time, the bridge housing is one of the main components of the running system. Structurally, it can be divided into integral bridge housing and segmented bridge housing.

[0003] Among the integral bridge housings, there are steel plate stamping and welding bridge housings, which are composed of a bridge housing main part, a steel leaf spring seat, a half-axle sleeve rear cover, etc. When welding, the bridge housing main part needs to be fixed by a fixture first, and then the components are welded together, such as the bridge housing welding fixture for automobile axle processing with publication number CN218695562U. First, the transmission sleeve is initially sleeved on the transmission screw, and the threads on the two sets of transmission screws are rotated in opposite directions, and the spring is in a natural state. When the bridge housing main part is fixed, the bridge housing main part is first placed on the processing table, and then the double-axis motor is started. The double-axis motor drives the two sets of drive shafts to rotate, and the drive shaft drives the two sets of transmission screws to rotate through the transmission of the pulley and the belt. Since the spiral rotation directions of the two sets of transmission screws are opposite, the two sets of transmission screws push the two sets of vertical plates to slide inward through the transmission sleeve. The vertical plate drives the clamping plate to clamp the bridge housing main part from both sides. When the vertical plate moves inward, it drives the push block to squeeze the conical top block. After the conical top block is squeezed, it pushes the push rod to move downward, and the push rod pushes the pressure plate to move downward. The spring is stretched, so that the pressure plate fixes the bridge housing main part from above. At this time, the push block is completely attached to the conical top block, preventing the spring from returning to the original position. In this way, the fixation of the bridge housing main part is completed. After fixation, the welding of various components can be carried out. However, the push block and vertical plate of the bridge housing welding tooling used for automobile axle processing are fixed to each other, and there are deviations in the shapes of equipment such as the main parts of axles of different models. Push blocks of a single shape can only be adapted to the bridge housing fixing processing of one model. When fixing different axle main parts in the car factory, multiple welding tools with push blocks of different shapes need to be set up, which is less practical.

[0004] Therefore, it is necessary to provide a bridge shell welding tool for automobile axle processing to solve the above technical problems. Utility Model Content
