Principle: The welding position of the workpiece is pneumatically pressed in the middle of the welding main beam with the copper piano key, and the tungsten electrode of the welding torch is aligned with the welding seam through the fine adjustment device of the cross welding torch, and then the automatic arc striking and straight gun walking are realized, and the workpiece is welded in a straight seam at one time. The welding speed of this machine is continuously adjustable, and the original DC motor and linear guide rail are adopted, so that the welding gun can walk at a constant speed without jitter, and the high-quality welding of the workpiece is ensured.

It adopts cantilever single-column structure, which is mainly composed of lathe bed, pneumatic keyboard fixture, beam guide rail, mandrel, electric carriage, pneumatic lifting mechanism of welding gun, three-dimensional adjusting mechanism of welding gun, gas path system and electrical control system.

The walking motor drives the welding gun to move with the linear moving trolley and the guide rail. Pneumatic keyboard clamp and copper gasket ensure uniform pressure and rapid heat dissipation, and the back of weld is beautifully formed.

Extended data

Main components and characteristics of automatic welding machine;

1, welding power supply. Its output power and welding characteristics should match the proposed welding process and method, and it is equipped with an interface connected with the main controller.

2. Wire feeder and its control and speed regulation system. For the wire feeder with high control accuracy of wire feeding speed, speed feedback should be added to its control circuit.

3. The welding head uses its moving mechanism. It is composed of welding head, welding head support frame, hanger and so on. It is based on precision welding head mechanism, and its driving system should adopt servo motor with encoder.

4, weldment movement or displacement mechanism. Such as welding wheel frame, head and tail frame turnover machine, rotating platform, positioner, etc. The precision moving positioner shall be driven by servo motor.
