Electric servo x-type robot welding gun

Abstract

The invention relates to a pair of electric servo X type robot soldering pliers, comprising a driving component, a protecting cover, a base plate, an upper plate, an upper electrode arm component, a lower electrode arm component, a water pipe component and a transformer component, wherein the driving component comprises a servo motor, a speed reducer, a ball screw and a connecting rod; the upper electrode arm component comprises an upper arm, an upper arm connecting block, an upper arm electrode rod and an upper arm electrode cap; the lower electrode arm component comprises a lower arm, a lower arm connecting block, a lower arm electrode rod and a lower arm electrode cap; the water pipe component comprises a distributor, an upper arm water inlet pipe, an upper arm water return pipe, a lower arm water inlet pipe, a lower arm water return pipe, a transformer water inlet pipe and a transformer water return pipe; and the transformer component comprises a transformer, a first copper bar, a second copper bar, a third copper bar and a soft copper bar. The modular design is adopted for the soldering pliers, so that the mounting and debugging are more convenient; and the servo technique is adopted, so that the control is accurate, the performance is reliable, the design is reasonable, and the service life is longer.

Description

technical field [0001] The invention relates to a robot welding device, in particular to an electric servo X-type robot welding tongs. Background technique [0002] At present, welding is a common processing technology in the automobile manufacturing industry. As one of them, spot welding is widely used in the automobile manufacturing industry. By clamping two pieces of metal, a large current is passed through a small contact surface instantly, melting and fusing the two pieces of metal, and the effect of solid connection is achieved after cooling. The spot welding process will not damage the internal structure of the workpiece, and there is no need to add other welding materials. Due to the different welding positions and postures, the requirements for welding tongs are also different, and they are generally divided into C-type welding tongs and X-type welding tongs. [0003] In recent years, the domestic automobile industry has developed rapidly, the degree of automation...

AI Technical Summary

Problems solved by technology

[0004] The current servo welding tongs generally adopt the following two methods: one is the cooperation of the servo motor with the synchronous toothed belt, because the synchronous toothed belt is prone to jump teeth during the operation, the control accuracy will be low during the use of the welding tongs; the synchronous toothed belt is used Short service life leads to short overall service life of the welding tongs; in addition, the servo hollow motor is the only welding tong manufacturer, the market is monopolized, and the welding tongs are expensive
