Single-welding-point laser welding device and using method

Abstract

The invention provides a single-welding-point laser welding device and a using method. The single-welding-point laser welding device solves the problems that the laser welding effect is poor and the like. The single-welding-point laser welding device comprises a rotary workbench, wherein a working panel is fixedly arranged on the rotary workbench; the working panel is provided with a plurality of welding stations which are symmetrical relative to the center of the working panel and extend outwards; clamp positioning assemblies are separately mounted on the welding stations; the rotary workbench is equipped with a lifting rotary air cylinder positioned below the welding stations; the output end above the lifting rotary air cylinder is connected with a C-shaped mounting frame which can rotatably lift relative to the welding stations; the end head above the C-shaped mounting frame is equipped with a pressing strip which extends downwards; the pressing strip is opposite to a welding part fixedly arranged on the welding stations, and the end head of the pressing strip is fixedly equipped with a rotary pressing head; and a laser welding gun is arranged above the welding stations. The single-welding-point laser welding device has the advantages of being good in welding effect, high in working efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of laser welding, and in particular relates to a single spot laser welding equipment and a use method. Background technique [0002] Laser welding can be achieved by continuous or pulsed laser beams. The principle of laser welding can be divided into heat conduction welding and laser deep penetration welding. The principle of heat conduction laser welding is: laser radiation heats the surface to be processed, and the surface heat diffuses to the inside through heat conduction. By controlling the laser pulse width, energy, peak power and repetition frequency and other laser parameters, the workpiece is melted to form a specific molten pool. . Laser deep penetration welding generally uses continuous laser beams to complete the connection of materials, and its metallurgical physical process is very similar to electron beam welding, that is, the energy conversion mechanism is completed through the "small hole" ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned solution solves the problem that the weldment is unevenly heated and easily deformed to a certain extent, but there are still many deficiencies in this solution, such as the weldment has multiple solder joints, resulting in poor welding results and other problems
