Abstract

The invention discloses a clamp and a process for machining a welding yoke of an automobile and belongs to the field of novel large automobile component manufacturing. The clamp consists of a mandril, a transition plate, a concentric positioning plate and a mandril rod, wherein the transition plate is arranged on the top of the mandril and is connected with the concentric positioning plate; and the mandril rod is connected with the mandril. A V-shaped body is fixed on the mandril innovatively, and the center of the V-shaped body is a radial center of a workpiece; and when the workpiece is clamped at the position of the center of the V-shaped body only, the V-shaped body can be concentric with the workpiece under any condition. Therefore, according to the principle, after machining one surface, two clamping spring grooves rotate 180 degrees to machine the other surface, so that the machining is separate, and the clamp is in the same center of the workpiece. The clamp meets the machining requirements of high-accuracy high-quality automobile parts in a general lathe.

Description

technical field [0001] The invention relates to the field of manufacturing new automobile parts, in particular to an automobile welding fork processing jig and process. Background technique [0002] At present, in the automobile industry, there is a double U-constant velocity center fork auto part, which is a new product of four-drive auto parts. One of the parts is called a welding fork. The structure of this welding fork is relatively complicated, and the corresponding processing is very difficult. High expectations. Ordinary processing technology is difficult to guarantee the processing requirements. There are two concentric holes matched with the cross shaft in the center of the automobile constant velocity center fork. The circlip groove requires a position accuracy of ±0.05, a coaxiality of 0.01, and a symmetry of 0.15. The spring groove must not only be concentric in the axial direction, but must also be concentric in the radial direction with the welding fork part...
