Welding locating device of spot welder of diaphragm capsule

A welding locating device of a spot welder of a diaphragm capsule comprises a rack and turntable. A diaphragm capsule locating groove used for containing the diaphragm capsule to be welded is formed in the turntable, the rack is provided with an upper welding mechanism and a lower welding mechanism, the upper welding mechanism and the lower welding mechanism are arranged on the upper side and the lower side of the turntable respectively and correspond to the position of the diaphragm capsule locating groove, and the upper welding mechanism and the lower welding mechanism are driven to move up and down through a welding air cylinder I and a welding air cylinder II respectively. The welding locating device of the spot welder of the diaphragm capsule is simple in structure, a whole welding process needs no manual operation, the labor intensity of workers is reduced greatly, and the welding locating device of the spot welder of the diaphragm capsule can achieve automatic welding, and greatly improves welding effi
