[0002] Most cylindrical / cylindrical components have annular welds that need to be welded. During welding, usually a person manually holds a welding gun and rotates it along the component to complete the welding of the annular weld. This operation mode in which the cylindrical / cylindrical component does not rotate and the welding gun is manually held and rotated along the component not only makes it difficult to ensure welding quality, but also has low production efficiency and is inconvenient to operate. The labor intensity is high. Therefore, it is necessary to develop a welding tool that can be applied to cylindrical / cylindrical components.

[0003] CN 206500834U discloses a "cylinder welding robot", which includes a frame, a workbench, a chute 1, a mobile platform 1, a support block, a rotating wheel, a slide rail, a mobile platform 2 and a welding robot. The workbench is arranged above the frame, a chute 1 is arranged on the workbench, the chute 1 is parallel to the extension direction of the workbench, a mobile platform 1 is slidably arranged on the chute, two support blocks are arranged on the mobile platform 1, the support blocks are arranged on both sides of the mobile platform 1, a rotating wheel is arranged on the support block through a rotating shaft, the rotating shaft is parallel to the chute 1, the slide rail is arranged on the side of the workbench, the slide rail is parallel to the chute 1, a mobile platform 2 is slidably arranged on the slide rail, and a welding robot is fixedly arranged on the mobile platform. The rotation of the rotating wheel drives the rotation of the cylindrical workpiece, and the welding gun does not need to be rotated along the workpiece during welding, which is convenient to use and has higher welding quality. Undoubtedly, the technical solution disclosed in the patent document is a beneficial attempt in the relevant technical field. Utility Model Content
