Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a connecting piece welding tool. Background Art

[0002] During the connector welding process, the welding clamping fixture primarily ensures the weld gap and provides a stable protective atmosphere. Welding quality is closely related to the flatness of the clamping head. The flatness of the clamping head's copper nozzle depends on the consistency of the guide shaft's locking nut position, which is often difficult to adjust and inspect. A clamping fixture with poor flatness will further reduce flatness during the continuous clamping process, reducing welding yield and increasing inspection costs. An unreasonable air blowing structure often deforms or becomes clogged by welding slag, affecting the blowing effect, resulting in uneven air flow and, in turn, affecting welding quality.

[0003] Based on the above technical problems, technicians in this field urgently need to develop a connecting piece welding tool with a simple structure that can ensure and judge the flatness of the pressure head, blow air evenly, and improve the welding yield. Utility Model Content
