Description

Technical Field

[0001] The utility model relates to a welding device, in particular to a welding device for an oil storage cylinder for rear shock absorption of a motorcycle. Background Art

[0002] At present, the motorcycle rear shock absorber oil storage tank, such as Figure 1 As shown, the oil reservoir 10 includes an oil storage pipe 10 and a damping cap 11 fixedly mounted at the lower end of the oil storage pipe 10. During the production of such motorcycle rear shock absorber oil reservoirs, CO2 shielded arc welding is often used to secure the oil storage pipe 10 and the damping cap 11. However, this CO2 shielded arc welding process requires manual control of the circumferential rotation of the oil storage pipe 10 and the damping cap 11, resulting in a low degree of automation and low production capacity. Summary of the Invention

[0008] The laser welding device includes a welding seat and a laser welding gun. The welding seat is arranged at the upper end of the workbench, and the laser welding gun is arranged at the upper end of the welding seat. The muzzle of the laser welding gun points to the connection between the damping cap and the oil storage pipe.

[0009] According to the above technical solution, when using the above welding device to weld an oil storage cylinder, the first step is to place the damping cap into the positioning groove, which is used to limit and support the damping cap. The second step is to place the oil storage pipe above the damping cap. The third step is to drive the pressing head downward by pressing the cylinder, so that the limiting end extends into the oil storage pipe and presses the oil storage pipe and the damping cap together. The fourth step is to control the support cap to rotate circumferentially by rotating the drive member. The fifth step is to weld the connection between the damping cap and the oil storage pipe using a laser welding gun. The damping cap support device drives the damping cap and the oil storage pipe to rotate circumferentially, replacing the manual operation of the operator. This makes the above welding device highly automated and has high production capacity. The oil storage pipe pressing device presses the damping cap and the oil storage pipe together. In this way, during the welding process, the damping cap and the oil storage pipe are not easily separated, the welding accuracy is improved, and the product stability is improved. Using laser welding instead of carbon dioxide shielded arc welding has the advantage of higher production capacity.
