Manual integrated electrode holder

Abstract

The invention discloses a manual integrated electrode holder, and belongs to the field of welding equipment. The manual integrated electrode holder comprise an electrode holder rotating disc, an electrode holder body, a hanging rod and an operating handle; the electrode holder rotating disc comprises an inner rotating disc, an outer rotating disc and a steel ball belt, and the electrode holder rotating disc comprises a locking structure for locking the inner rotating disc and the outer rotating disc; the electrode holder body comprises a static electrode holder arm and a movable electrode holder arm which are mounted on one end surface of the inner rotating disc, and a multi-stage pressurizing cylinder, a medium-frequency transformer, a control valve, a water-gas adapter and a wire collecting plate which are mounted on the other end surface of the inner rotating disc; one end of the hanging rod is fixed on the outer rotating disc, and the other end of the hanging rod is used for hanging; the operating handle is fixed on the electrode holder body or the inner rotating disc, the operating handle is electrically connected with the wire collecting plate, and the operating handle operates the control valve arranged on an air pipe through the wire collecting plate so as to control the multi-stage pressurizing cylinder to work, so that an electrode on the movable electrode holder armis close to or away from an electrode on the static electrode holder arm. According to the manual integrated electrode holder, the limitation of a bearing is overcome, and the pressure applied to a workpiece can be increased under the condition of not increasing the volume structure.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to a manual integrated welding tongs. Background technique [0002] With the development of industries such as aerospace, electronics, automobiles, and household appliances, welding technology is widely used in industrial production. Among them, the advantages of resistance welding technology, such as low welding cost, high production efficiency, good welding quality, simple operation, and easy realization of mechanization and automation, have been widely valued. [0003] Spot welding technology is a kind of resistance welding. Spot welding is to assemble the weldment into a lap joint, and press it between two columnar electrodes, and use resistance heat to melt the metal of the workpiece (base material) to form a resistance welding of the solder joint. method. [0004] And manual integrated welding tongs (also known as spot welding machine, hereinafter referred to as welding tong...
