Rear axle flange ring welding device with adjusting structure and for automobile

Abstract

The invention relates to the technical field of flange ring welding, in particular to a rear axle flange ring welding device with an adjusting structure and for an automobile. The rear axle flange ring welding device comprises a rear axle and a welding frame arranged at the bottom of the rear axle. The welding frame comprises two supporting plates, the two supporting plates are correspondingly arranged on the left side and the right side of the rear axle, the rear axle comprises a drive axle housing, a hub is arranged at the end of the drive axle housing, and an adjusting mechanism is arrangedat the position, close to the front side, between the two supporting plates. A fixing device is arranged, the drive axle housing is fixed through static friction force generated by an anti-skid pad and a bottom fixing groove, the phenomena of rotation and skid of the drive axle housing are avoided, and the operation difficulty of welding personnel during welding is reduced; and the height of thewelding rear axle is adjusted through a telescopic cross beam, so that the welding position at the bottom is flush with the face of the welding personnel, the splashing amount of welding sparks flyingto the face is reduced, and the risk that the face is scalded by the welding sparks is reduced.

Description

technical field [0001] The invention relates to the technical field of flange ring welding, in particular to a rear axle flange ring welding device with an adjusting structure for automobiles. Background technique [0002] The reducer and differential of the car need to be fixed in the middle of the rear axle through the flange ring, so the flange ring needs to be welded on the rear axle first. Since the drive axle housing of the rear axle is a cylindrical structure, it is usually welded The drive axle housing is supported by two "Y"-shaped support frames to achieve the purpose of supporting the rear axle, and then welded. [0003] However, the drive axle housing of the rear axle cannot be fixed when supported by the "Y"-shaped support frame, and it is easy to slip during the welding process, thereby increasing the welding difficulty of the welding personnel. Moreover, the height of the support frame cannot be adjusted during support. Adjust, so that when welding the bottom...

Problems solved by technology

[0003] However, the drive axle housing of the rear axle cannot be fixed when supported by the "Y"-shaped support frame, and it is easy to slip during the welding process, thereby increasing the welding difficulty of the welding personnel. Moreover, the height of the support frame cannot be adjusted during support. Adjust, so that when welding the bottom of the flange ring, the welder needs to lie on the ground to operate, with his face facing upward, so that welding stars can easily splash on the face of the welder and cause burns
