Abstract

This invention discloses a welding device for automotive rear axle housings, belonging to the field of rear axle housing welding technology. It includes a base, with a chuck fixing seat fixedly mounted on one side of the top of the base. A stepper motor is fixedly mounted inside the chuck fixing seat, and the output end of the stepper motor extends out of one side of the chuck fixing seat and is fixedly connected to an electric chuck. By setting the chuck fixing seat and the internal stepper motor and electric chuck on the top of the base, and cooperating with the first electric telescopic rod, rotating seat, and clamping sleeve on the clamping frame, precise clamping of both ends of the rear axle body is achieved. Simultaneously, the two third electric telescopic rods and the pre-clamping frame in the pre-clamping mechanism pre-position and support the middle section of the rear axle body, forming a three-point positioning structure of "fixed ends + middle section support." This structure significantly improves the positioning accuracy and stability of the rear axle body, effectively reduces welding deformation, and improves the quality of the welded joint and the overall strength of the rear axle housing.
