Description

Technical Field

[0001] The utility model relates to the technical field of stud welding, in particular to a stud welding nail connection device. Background Art

[0002] Stud welding nail is a special type of threaded part used for connecting metal components. It usually consists of two parts: a stud with threads and a welding nail welded to the component. The stud part is usually cylindrical with external threads for matching with nuts or other threaded parts. The welding nail part is usually cylindrical with a welding end for welding with metal components.

[0003] In the prior art, a Chinese patent with publication number "CN209206681U" discloses a magazine-type stud welding gun, which realizes magazine-type stud feeding through ingenious design of a stud magazine, a rotating stud barrel and a stud feeding ejector pin, and can easily load multiple studs at a time and realize automatic stud feeding, which can not only avoid the pain caused to welding workers by manual filling, but also realize continuous welding for a certain period of time, so that the efficiency of manual welding is significantly improved, and the existing defect of manual filling is solved. The studs must be stuffed into the welding gun chuck one by one with fingers, and the welding volume per day is about 7,000 to 10,000. At the end of the day, the fingers of the welders are seriously damaged. In addition, the operation mode of only loading one stud at a time also seriously affects the welding efficiency.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] During the welding process of stud welding, the stud welding nails are inserted into the metal components to be welded, and their positions are ensured to be accurate and stable. Then, the metal components and stud welding nails are clamped and fixed with clamps or other clamping devices to ensure stability and alignment during the welding process. In this process, the stud welding nails need to be pressed manually to ensure the quality and stability of the welded joints. However, this wastes manpower. After working for a long time, the personnel will also become tired, which will affect the efficiency of the stud welding connection. Utility Model Content
