A flange head and axle housing body assembly spot welding fixture

Abstract

The invention relates to a flange head and axle housing body assembly splicing point solid welding clamp which comprises a rack, a head and tail machine base, a flange head locating and clamping device, a flange head appearance locating device, an axle housing body assembly radial locating device and an axle housing body assembly center locating device. Flange heads and axle body assemblies need to be spliced in the production process of various stamped and welding axle housing assemblies, different locating cores and angle blocks are designed for the flange heads in different shapes and with different sizes, different clamping jaws are designed for different axle housing body assemblies, workpieces of different lengths meet length needs by adjusting the head and tail machine base, the production efficiency is high, and high universality is achieved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a spot welding jig for assembling a flange head and an axle housing body assembly. Background technique [0002] In the field of mechanical processing of automobile axle housings, the relevant parts of the rear axle housing assembly need to be assembled in the production process of various domestic or foreign stamped and welded axle housing assemblies. The assembly needs to ensure the concentricity, symmetry and length of the flange heads at both ends. In order to achieve this function, the welding fixture and welding process can quickly and accurately complete the positioning and clamping of the flange head and the axle housing body assembly. Spot welding completes the assembly. [0003] The Chinese patent announcement number is CN105458606 A, which discloses an assembly and welding fixture for the axle housing body, including a frame, a headstock assembly, a tailstock asse...
