Abstract

The invention relates to a projection welding tool. The projection welding tool comprises a main machine as well as an upper electrode assembly and a lower electrode assembly which are arranged on themain machine, and further comprises a positioning system for fixing a to-be-welded workpiece group, wherein the to-be-welded workpiece group comprises a first plate-shaped workpiece and a second screen board shaped workpiece; the positioning system comprises a horizontal positioning mechanism for fixing the first workpiece and a vertical positioning mechanism for fixing the second workpiece ontothe first workpiece; the vertical positioning mechanism comprises a rack and at least two buffer units which are arranged on the rack; and each buffer unit is used for vertically pressing the second workpiece and the first workpiece. Compared with the prior art, the projection welding tool can be used for accurately positioning the to-be-welded workpiece group, improves welding efficiency and guarantees welding quality; besides, the vertical positioning mechanism comprises the plurality of buffer units, and each buffer unit can vertically apply pressure to the second workpiece and the first workpiece, so that the situation that the second screen board shaped workpiece deforms in a welding process is avoided, flatness of a welded finished product is guaranteed, and welding quality is further guaranteed.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to a projection welding tool. Background technique [0002] The door of the microwave oven is welded by the iron door body and the mesh plate. The traditional welding device generally uses circular electrodes for welding. When welding, only one or a few points can be welded at a time, and the welding power is low. For example, the application number is CN201310734351 .0 (publication number is CN104741753A) Chinese invention patent "High Efficiency Spot Welding Machine", patent number is ZL201110099706.4 (publication number is CN102179614B) Chinese invention patent "contact conductive device for single point welding machine" etc. machine structure. For this reason, the Chinese invention patent "A Steel Grid Welding Machine" with the patent No. ZL200710015496.X (announcement No. CN101049651A), and the Chinese invention patent "Intermediate Frequency Inversion Grid" with application N...
