Abstract

The invention discloses an automatic laser welding device. The device comprises a butterfly-shaped process screw rod I, a clamping mechanism, a butterfly-shaped process screw rod II, a laser welding head, a back gas protection cavity, a butterfly-shaped process screw rod III, a compressible sealing gasket, a welding table, clamping grooves, process pins, a delay protection gas spray head, a side blowing protection gas spray head, a gas inlet pipe and a laser welding machine head, the clamping grooves are located in the two sides of the welding table and fixed to the welding table to form a whole, the clamping mechanism and the clamping grooves are provided with holes for assembly and positioning of the process pins, and the clamping mechanism and the clamping grooves can be connected to the side surface of the welding table surface through the process pins, and the butterfly-shaped process screw I and the butterfly-shaped process screw II are mounted on the clamping mechanism and are screwed with threaded holes in the clamping mechanism to fasten a part I to be welded and a part II to be welded. The automatic laser welding device can effectively avoid the problem of repeated positioning of parts in the batch production process, and can avoid the problems that the positioning precision is not high and the gas protection effect of the weld joint position is poor during welding.

Description

technical field

[0001] The invention belongs to the technical field of automatic laser welding processing, and specifically relates to a positioning repair and gas protection in the process of automatic laser welding, so as to avoid repeated positioning of parts during mass production or low positioning accuracy and gas in the welding seam during the welding process. The method with poor protection effect and unstable weld structure formation. Background technique

[0002] Automated laser welding has been highly valued by the manufacturing industry because of its many advantages such as fast welding speed, small heat-affected zone, uniform weld shape, weld height and shortness, and small deformation. Replacing traditional welding and riveting can effectively reduce the overall weight of parts and improve the overall quality of parts. However, due to the strict requirements of laser welding on the fit gap and misalignment of the weld, as well as the deformation of the parts ...
