Problems solved by technology

[0003] In the actual friction stir welding process, the friction stir welding equipment used in the industry often adopts a fixed worktable, and realizes the welding between metals through the movement of the X-axis, Y-axis and other directions of the stirring head, so that the equipment volume is relatively small. Huge and bulky, resulting in high equipment production costs, which greatly limits the application of friction stir welding technology in the civil industry, and

Abstract

The invention provides friction-stir welding equipment. The friction-stir welding equipment comprises a machine tool body for friction-stir welding. A stir head is installed on a spindle of the machine tool body. A floating supporting structure is arranged between the stir head and the spindle and comprises a connecting component and an elastic supporting piece. The connecting component is fixed to the spindle, the lower portion of the connecting component and the upper portion of the stir head are matched through a plurality of concave parts and convex parts, and the connecting component and the stir head can rotate synchronously. The elastic supporting piece is arranged between the lower end of the connecting component and the upper end of the stir head in an abutting mode. A limiting structure is arranged on the connecting component and used for preventing the stir head from disengaging from the lower end of the connecting component. The friction-stir welding equipment can keep pressure constant in welding and improve the quality of welded joints. When disturbance or other accidents occur, torsion or impact force on the stir head can be reduced, so that the stir head is easy to protect and not prone to fracture, and the service life of the stir head is prolonged. The structure of the spindle is simplified, so that the whole equipment has a light weight and a small size, materials are saved, and cost is lowered.

Description

technical field [0001] The invention relates to the field of friction stir welding equipment, in particular to a friction stir welding equipment. Background technique [0002] Friction stir welding is an invention patent proposed by the British Welding Institute in October 1991. The friction stir welding process was originally mainly used to solve the welding of low melting point materials such as aluminum alloys. As an advanced solid-phase joining technology, friction stir welding is widely used in aerospace, rail transit, national defense and military industry, ships and automobiles and other fields. In the process of friction stir welding, a stirring head is used to insert the part to be welded of the workpiece, and through the friction stirring between the stirring head and the workpiece, the friction heat makes the metal in this part in a thermoplastic state and is plasticized from the front end to the rear under the pressure of the stirring head flow, so that the par...
