Description

Technical Field

[0001] The utility model relates to the technical field of handheld welding gun auxiliary fixtures, in particular to a handheld laser welding gun auxiliary welding fixture. Background Art

[0002] Laser welding is a new type of welding method. Compared with traditional double-container welding and argon arc welding, it has significant advantages such as high welding efficiency and less harm. The laser welding widely used in industrial practice is currently realized by a handheld laser welding gun + laser generator + water cooling system. The welding fixture is a welding fixture specially designed and manufactured according to the dimensional coordinate points of the welded parts calibrated during the design of the welding product.

[0003] The existing technology requires the user to perform manual welding with a handheld laser welding gun. During the welding process, whether the movement trajectory of the welding gun head is consistent with the weld is the most important factor affecting the welding quality and weld appearance. Therefore, during the welding process, the user needs to concentrate on controlling the hand movements to make the movement trajectory of the welding gun head consistent with the weld as much as possible. During welding, a laser armor cable is plugged into the back of the welding gun. The weight of the armor cable plus the welding gun is usually around 2 kilograms, which brings a large load to the user's hands. The hands are heavy, so on the one hand, users are reluctant to switch from traditional welding to laser welding. On the other hand, in order to ensure the welding effect, users have to spend extra effort to maintain the stable position of the welding gun and the correct and continuous welding trajectory; long-term use also brings challenges to the health of the user's hands.
