[0001] The utility model relates to the technical field of friction stir welding, in particular to a friction stir welding device for hub manufacturing. BACKGROUND

[0002] Friction stir welding refers to the heat generated by the friction between a high-speed rotating welding tool and a workpiece to locally melt the material to be welded. When the welding tool moves forward along the welding interface, the plasticized material flows from the front to the rear 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.

[0003] The welding assembly of the existing friction stir welding device can only move vertically up and down. The workpiece needs to be moved by the clamping device during welding to complete the welding of the workpiece. However, this welding method cannot continuously weld the hub workpiece with an arc-shaped surface and an angle. Therefore, the position and angle of the workpiece need to be frequently adjusted when clamped in the clamping device during welding. The welding of the hub workpiece is relatively time-consuming and labor-intensive, and the use is relatively inconvenient. Therefore, we propose a friction stir welding device for hub manufacturing to solve or improve the above problems. SUMMARY
