A clamping and positioning device for laser tailor welding

Abstract

The invention discloses a tailored blank laser welding clamping positioning device. The tailored blank laser welding clamping positioning device comprises a workbench, one side of the workbench is provided with push clamping parts, and the other side of the workbench is provided with a positioning part; after a to-be-welded plate is pushed into clamping mechanisms from the positioning part, and second clamping plates cover first clamping plates, the to-be-welded plate is clamped; and then, pushing hands of power mechanisms push the clamping mechanisms to go forwards along the workbench to a welding position. As for a tailored blank laser welding production line, clamping and positioning of the to-be-welded plate are completed at the same time, then, laser welding is directly conducted; theeffect that tailored blank laser welding is conducted successfully is ensured, and after welding, clamping is released while positioning is stopped; and the whole process is reliable in operation, positioning of each time is accurate, the working efficiency is high, and the tailored blank laser welding burden of workers is relieved. The tailored blank laser welding clamping positioning device canposition two profile sheets subjected to tailored blank laser welding, the yield of finished products subjected to tailored blank laser welding is increased, the structure is simple, and the securitycoefficient is large.

Description

technical field [0001] The invention relates to the field of laser tailor welding, in particular to a fixture used in the laser tailor welding process. Background technique [0002] In recent years, laser processing technology is a high technology integrating optics, mechanics, electronics, computer science, etc. sexual technological change. Specifically, laser processing is a processing process in which high-energy laser beams are focused on the surface of the processed object, thereby causing changes in the shape of the object or changes in the properties of the object. Laser thermal processing refers to various processing processes caused by the rapid thermal effect caused by the laser beam acting on the object. It can cut, punch, groove, mark, etc. metal or non-metal materials, and can also weld and surface metal materials. Strengthening, cutting, etc. Laser processing has many advantages such as fast speed, high processing quality and high efficiency. [0003] Altho...

AI Technical Summary

Problems solved by technology

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
