Abstract

The invention provides a weld positioning device. In order to prevent distortion in the process of welding, a frame rail to be welded is clamped in a positioning track formed by a plurality of positioning mechanisms; and the frame rail is clamped in a split fixing way in an all-surrounding mode. In order to reduce welding deformation in an upward direction and a downward direction of the frame rail in the process of designing the weld positioning device, a reversible deformation measure is designed on the weld positioning device in advance according to deformation tendency. A positioning molded surface in the weld positioning device is arranged into a convex design with higher middle part and lower both ends by aiming at the deformation tendency of bent both ends of a frame rail assembly so as to reduce welding deformation. The weld positioning device can effectively solve the problem of distortion in the process of welding the frame rail and improves quality state of frame rail products.

Description

technical field [0001] The invention relates to a welding positioning device, in particular to a welding positioning mechanism for a longitudinal beam of an automobile frame, and belongs to the technical field of mechanical manufacturing. Background technique [0002] The car frame stringer is an important part of the car frame, and the twist of the frame stringer will directly affect the stability of the entire car frame and the yield of the car. Since the existing frame longitudinal beams are all formed by welding, and the welding method used in the welding process of the frame longitudinal beam assembly is mostly carbon dioxide gas shielded welding (ie CO 2 Welding), there is a certain welding deformation of the frame longitudinal beam after welding, which mainly includes two aspects: one is the distortion deformation of the frame longitudinal beam from head to tail after welding, and the other is the bending of both ends of the frame longitudinal beam after welding , Th...
