A laser tailor welding positioning device

Abstract

The invention relates to the technical field of laser welding, in particular to a tailored blank laser welding positioning device which comprises a first tailor welding material piece, a second tailor welding material piece and a positioning platform. The positioning platform is provided with an upper groove and a right groove which are used for containing the first tailor welding material piece, and a lower groove and a left groove which are used for containing the second tailor welding material piece, and a left positioning rod and a right positioning rod which are used for simultaneously abutting against the first tailor welding material piece and the second tailor welding material piece, wherein the first tailor welding material piece and the second tailor welding material piece are both L-shaped material pieces of the same specification. During tailor welding, the left positioning rod moves forward along a left positioning sleeve so as to simultaneously abut against the left side area of the first tailor welding material piece and the left side area of the second tailor welding material piece, and the right positioning rod moves forward along a right positioning sleeve so as to simultaneously abut against the right side area of the first tailor welding material piece and the right side area of the second tailor welding material piece. Visibly, the tailored blank laser welding positioning device can position the two L-shaped material pieces where tailored blank laser welding is conducted, can increase the yield of tailor welding finished products, and is simple in structure and high in safety coefficient.

Description

technical field [0001] The invention relates to the technical field of laser welding processing, in particular to a laser tailor welding positioning device. Background technique [0002] During laser tailor welding, two pieces of material are placed on the table, and tailor welding can start after alignment. However, in the process of tailor welding, since there is no further reinforcement of the parts of the material, the splicing of the two materials will be continuously stimulated by high-energy lasers, which will cause subtle changes in the positions of the two materials to varying degrees. Such a position change directly leads to a decrease in the yield rate of tailor-welded finished products. In order to prevent such slight position changes, some workers use hand-held jigs to fix the blanks, but this will cause inconvenience in tailor welding operations, reduce work efficiency, and cause certain safety hazards to workers who hold the jigs.

However, in the process of tailor welding operation, since there is no further reinforcement of the parts of the material, the splicing of the two pieces of material will be continuously stimulated by the high-energy laser, so that the two pieces of material will have different degrees of subtle position changes

Such a position change directly leads to a decline in the yield of tailor-welded finished products

In order to prevent such slight position changes, some workers use hand-held clamps to fix the blanks, but doing so will cause inconvenience in tailor welding operations, reduce work efficiency, and cause certain safety hazards to workers holding clamps
