Description

Technical Field

[0001] The utility model relates to the technical field of spot welding machines, in particular to a spot welding machine used for welding automobile parts. Background Art

[0002] Spot welding robots are important equipment in the welding of automotive parts. They can achieve efficient, accurate and reliable welding operations. This type of robot uses advanced computer control technology to achieve high-precision positioning and welding, ensuring the welding quality and consistency of parts.

[0003] For example, a spot welding robot for welding disclosed in the existing publication number CN219151842U has a plurality of rotating components arranged in the middle of the spot welding robot. Through the cooperation between the plurality of rotating components, the spot welding robot can be rotated and moved forward and backward, and can also be moved up and down, thereby making the moving range of the spot welding robot wider and the operating space larger. Although the application realizes that the moving range of the spot welding robot becomes wider, when welding parts such as the body of a car, due to the limited maximum spacing between the two welding rods at the end of the spot welding robot, when welding parts such as the body of a car, the insertion depth of the two welding rods at its end is limited, so that some welding points cannot be welded. Therefore, it is necessary to disassemble and adjust the positions of the two welding rods at the end of the spot welding robot to realize the insertion depth adjustment during welding. Therefore, in the actual operation process, it is necessary to replace the structure at the end of the spot welding robot, which increases the difficulty of operation and reduces the replacement efficiency of the welding structure.
