Embodiment Construction

[0014] Such as figure 1 Shown is a schematic structural view of the present invention, including: a host computer, an annular upper splint 1, a lower splint 5 corresponding to the upper splint 1, and a driving mechanism 3 for driving the upper splint 1 to move up and down. A protruding ring 1a is provided on the inner wall of the lower end of the upper splint 1 to increase the contact area between the upper splint 1 and the workpiece, and further reduce the deflection of the workpiece during welding. The driving mechanism 3 is fixedly connected with the friction stir spot welding equipment; the stirring head 2 of the friction stir spot welding equipment penetrates the upper splint 1 and is arranged vertically to the welding seam. Preferably, the driving mechanism 3 is an air cylinder.

[0015] When working, the upper computer starts the driving mechanism 3, the upper splint 1 moves downward and cooperates with the lower splint 5 to clamp the workpiece to be welded, and starts...

Abstract

The invention relates to friction stir spot welding (FSSW) equipment with an automatic clamping device. The FSSW equipment comprises an upper computer, a ring-shaped upper clamping plate, a lower clamping plate arranged corresponding to the upper clamping plate and a driving mechanism used for driving the upper clamping plate to move up and down. The driving mechanism is fixedly connected with the FSSW equipment. A stir head of the FSSW equipment penetrates the upper clamping plate and is perpendicular to a weld joint. The upper computer starts the driving mechanism; the upper clamping plate moves downwards to be matched with the lower clamping plate to clamp a workpiece to be welded; the stir head is started; when welding is completed, the stir head begins to Retreat; and simultaneously the upper clamping plate is controlled by the driving mechanism to move upwards, and the workpiece is unclamped. According to the FSSW equipment, the upper clamping plate is matched with the lower clamping plate, so that the workpiece clamping action is achieved, and the phenomenon of the flexure on the periphery of a welding spot of the workpiece in the welding process of the workpiece is avoided.

Description

technical field [0001] The invention relates to a friction stir spot welding equipment with a self-clamping device, which belongs to the field of welding technology. Background technique [0002] Friction Stir Spot Welding (Friction Stir Spot Welding, FSSW) is an innovative welding technology recently researched and developed on the basis of "linear" friction stir welding. FSSW can form spot welded lap joints, and its weld appearance is similar to that of resistance spot welding commonly used in aluminum alloy components, so it has high application value and research significance. Fundamentals of Friction Stir Spot Welding Currently, two different FSSW techniques are reported in the published literature. [0003] The first method is the friction stir spot welding invented by Mazda Motor Company of Japan in 1993. This friction stir spot welding is also called "friction stir spot welding with exit hole" technology. The welding equipment used is the same as that of ordinary fr...
