Description

Technical Field

[0001] The utility model relates to the technical field of friction stir welding, in particular to auxiliary transport equipment for friction stir welding. Background Art

[0002] Friction stir welding uses the heat generated by the friction between the high-speed rotating welding tool and the workpiece to partially melt the material to be welded. The welding tool moves along the gap to be welded. The plasticized material flows from the front to the back of the welding tool under the action of the rotating friction force of the welding tool, and forms a dense solid phase weld under the extrusion of the welding tool. It is widely used in aerospace, automobile manufacturing, railway transportation and other fields.

[0003] After searching, in the prior art, a Chinese patent with patent application number CN116900469A discloses an auxiliary transfer device for stir friction welding, including a linear transfer structure, which is arranged on a welding workbench for workpiece welding, and a stir friction welding head for workpiece welding is arranged at the bottom of the linear transfer structure, a flattening component is arranged on the front side of the linear transfer structure, and also includes two left-right symmetrical cleaning components, which are respectively arranged on the rear side of the flattening component; a waste collection component, which is arranged on the rear side of the stir friction welding head, but there are still the following defects:

[0004] (1) The top of the waste collection component in the above patent document is designed to be open. When the cleaning component is used to clean the stir friction welding joint, the rotation of the cleaning brush will cause the residual debris to splash, resulting in a decrease in the collection effect of the residual debris.

[0005] (2) In the above patent document, the cleaning component is arranged on the moving axis of the mounting seat. When the position of the friction stir welding head is adjusted, the cleaning component will interfere with the moving trajectory of the friction stir welding head and shorten the moving stroke of the friction stir welding head.

[0006] Therefore, we make improvements on this and propose an auxiliary transfer equipment for stir friction welding. Utility Model Content
