Title:
SWING/ROTATING GAS METAL ARC WELDING TORCH AND USE METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/218005
Kind Code:
A1
Abstract:
A swing/rotating gas metal arc welding torch, comprising a hollow shaft motor (4) and a feeder panel. An upper extending shaft (11a) of the feeder panel penetrates through a brush mechanism, a lower extending shaft (4a) of the hollow shaft motor (4) is fixedly connected to the upper extending shaft (11a) of the feeder panel in a motor base (9) by means of a coupling (5), and a lower extending shaft (11b) of the feeder panel penetrates through a support bearing (12) mounted in a brush base (14) and is then connected to an eccentric or bent conductive rod mechanism; the motor base (9) is fixedly connected to the brush base (14) by means of connecting screws, and a welding shielding gas is provided and welding torch cooling is achieved by means of inner holes of the connecting screws as well as a built-in gas passage and a cooling water passage of the brush base (14); the arc swing/rotating frequency or an arc swing midpoint is detected by means of a built-in photoelectric encoder of a servo motor; the length of the conductive rod mechanism is adjusted by means of modulation or extension and retraction. The welding torch is simple and compact in structure, high in transmission positioning precision, good in process adaptability, high in practicability, suitable for swing and rotating gas metal arc welding, and expandable and applicable to submerged arc welding. Also provided is a use method for a swing/rotating gas metal arc welding torch.
