Accumulated chipping removing device of stir friction spot welding apparatus

Abstract

The invention discloses an accumulated chipping removing device of a stir friction spot welding apparatus. The accumulated chipping removing device comprises an upper computer, an electromagnetic coil and a high pressure gas source, wherein the high pressure gas source is communicated with an inner cavity of a jacket of a stirring head by a high pressure pipe; a gas inlet is formed in a sleeve of the stirring head; the gas inlet penetrates through the side wall of the sleeve and is corresponding to a gas outlet of the high pressure pipe; the high pressure pipe is connected with an electropneumatic valve; the electropneumatic valve is in signal connection with the upper computer; the electromagnetic heating coil encircles the jacket; a power supply circuit of the electromagnetic heating coil is provided with an electromagnetic switch; and the electromagnetic switch is also in signal connection with the upper computer. According to the accumulated chipping removing device of a stir friction spot welding apparatus, accumulated chippings are discharged from beneath the stirring head by virtue of high pressure draft; meanwhile, the electromagnetic heating coil is used for heating the stirring head, the accumulated chippings which are accumulated inside the stirring head are heated to form a fusion state, so that the accumulated chippings are favorably discharged, and the chipping removing work efficiency is improved; and compared with a mode that the accumulated chippings are discharged by a chemical soak solution, the accumulated chipping removing device has the advantages that the efficiency is high and no pollution is caused.

Description

technical field [0001] The invention relates to a device for removing accumulated chips of friction stir spot welding equipment, and belongs to the technical field of friction stir spot welding equipment. 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. The basic principle of friction stir spot welding At present, two different FSSW technologies have been reported in published materials, specifically: friction stir spot welding invented by Mazda Motor Company of Japan in 1993 and stirring technology invented by GKSS Research Center of Germany in 1999 Friction spot welding.
