【Equipment composition】

1.Machine Body

Consist of base and stand column. Positioning fixture and column are fixed in the base. The horizontal plate of base is used as installed datum plan, pneumatic clamped mechanism is installed in the column.

2.Welding Torch Rotation Mechanism.

It is composed of AC frequency motor, reducer and welding torch clamping mechanism. The rotation speed is adjusted by controlling driver to adjust motor speed. Reducer with worm and gear reducer, aluminum shell, the high output torque, easy installation and maintenance. Rotation head is configured with air and electric distributing ring, lead shielding gas and welding current to welding torch. Welding torch can rotate continuously, without tangling of air tubes. Wire feeder is placed in the base, safe and reliable. There are two doors in the left and right sides of base. Easy to maintain and change the welding wire disk.

3.Torch Clamping & Adjustment Mechanism

It adopts push-type wire feeding mode, to guarantee feeding stability. Welding torch can be adjusted up and down, left and right, or angle turn. The fine adjustment of torch uses the combination of ball screw and guide post, with high accurate adjustment and positioning. It can be locked after adjusting. Whole regulation can satisfy any angle welding, to conform the need of workpiece.

4.Workpiece Clamping and Adjustment Mechanism

Workpiece adopts v-shape symmetrical clamping type, synchronous adjustment by positive and negative rack and pinion. Driven by air cylinder, reach the function of automatically determining the center position. It is convenient and flexible to clamp workpiece. Clamping fixture locates in the outrigger, outrigger can be adjusted forword&backword, left&right. It is convenient to adjust the clamping center of workpiece.Additionally, machine has assistant fixture suits to different oil pipes which can not use V-shape fixture.
