Description

Technical Field

[0001] The utility model relates to the technical field of automobile bracket processing, in particular to a welding tool used for automobile bracket processing. Background Art

[0002] Existing welding equipment used in automobile production is generally driven by a robotic arm and has good precision. Although the welding gun can be adjusted relatively freely during the welding process, it is not easy to always keep the direction of the welding gun perpendicular to the weld. This leads to a decrease in welding strength during inclined contact, making the welding thickness of the entire weld uneven, which is not conducive to stable load bearing.

[0003] To solve the above problem, there is a solution for automobile bracket welding tooling (Announcement No. CN218657499U), which sets the clamping part of the tooling in a rotatable form, drives the rotation of the welding itself to compensate for the angle that the welding gun cannot reach, and increases the probability of the welding head contacting perpendicular to the weld.

[0004] However, in the actual production process, the side or other parts of the automobile bracket are often welded. The above welding tool can only rotate and adjust the automobile bracket, which has certain limitations during welding. It is difficult to complete all welding work of the automobile bracket in one clamping. Utility Model Content
