Abstract

The invention belongs to the technical field of metal welding and relates to a friction-stir welding device applied to a numerically-controlled machine tool. Positioning modules are mounted on a clamping module to jointly realize positioning and clamping functions along with the clamping module. A welding operating module is mounted on a spindle of the numerically-controlled machine tool to realize rotating and linear motion, and a driving module drives the clamping module to move. A direct-current loading module is positioned on the welding operating module. Magnetic field loading modules aremounted in the welding operating module and the clamping module, and welding of parts is finally realized. The friction-stir welding device has advantages that novel structure, simplicity, high universality and quickness in reaction are realized, and sheets different in size and thickness can be welded; weld joints in different shapes can be welded by the friction-stir welding device used with the numerically-controlled machine tool, and a welding direction and the horizontal plane always form a 2-degree inclination angle in a welding process to realize complete fluidity of weld joint materials; short-distance high current loading and magnetic field loading can be realized so as to achieve excellent weld joint performances.

Description

technical field [0001] The invention relates to the technical field of metal welding, in particular to a friction stir welding device applied to a numerically controlled machine tool. The present invention can weld thin plates of different sizes and thicknesses; cooperate with numerical control machine tools to weld welds of different shapes, and meet the requirement that during the welding process, the welding direction and the horizontal plane always form an inclination angle of 2°, so as to satisfy the sufficient fluidity of the weld material; The invention can realize short-distance large current loading and magnetic field loading, so that the performance of the weld seam is more excellent. Background technique [0002] Since the British Welding Institute invented an advanced solid-phase joining technology for aluminum alloys—friction stir welding—in 1991, compared with traditional welding, it has the characteristics of high efficiency, low energy consumption, small defo...
