AI Technical Summary

Technical Problem

Existing laser welding devices for automotive parts have factors such as heat conduction, mechanical constraints and impurity accumulation during the welding process, which affect welding quality, workpiece accuracy, production efficiency and tooling life, and also pose safety hazards.

Method used

A laser welding device for automobile shift forks is designed, which includes a clamping device, a protective device and a recovery device. The clamping device is designed by rotating the elastic telescopic clamp and the template. The protective device prevents high-temperature particles from splashing by using a protective plate and a triangular plate structure. The recovery device recovers particles through a collection basket and a spring structure.

Benefits of technology

It improves welding quality and workpiece accuracy, reduces thermal stress concentration and wave-shaped deformation, reduces safety hazards, improves production efficiency and reduces the number of shutdowns for slag cleaning.

Abstract

The invention discloses an automobile shifting fork laser welding device and relates to the technical field of laser welding machines, the automobile shifting fork laser welding device comprises a sliding frame, a rotating plate and an irregular rod, the sliding frame is slidably mounted on the front face of the laser welding machine, one end of the rotating plate is rotatably mounted at the bottom of the sliding frame, and the irregular rod is rotatably mounted at the other end of the rotating plate; when the cover plate moves towards the two sides, a welding part clamped by the elastic telescopic clamp is suspended, thermal stress distribution is more uniform, the stress concentration phenomenon in the welded workpiece is relieved, heat is more concentrated in a laser irradiation area, the temperature rise of a non-welding part is limited, and wavy deformation caused by heating and softening of peripheral materials is avoided.
