Description

TECHNICAL FIELD

[0001] The utility model relates to an automatic welding auxiliary equipment, especially an argon arc wire feeding pendulum mechanism. BACKGROUND

[0002] The pendulum mechanism is an automatic welding auxiliary equipment, which makes the welding torch reciprocate along a predetermined trajectory to achieve uniform welding. This mechanism improves welding efficiency and quality, reduces manual operation, and is suitable for pipeline and circular workpiece welding, and is one of the key technologies of modern welding automation.

[0003] The existing pendulum mechanism usually uses a stepper motor and a worm gear reducer to achieve precise control. The stepper motor drives the welding torch to perform precise pendulum motion through the conversion of the worm gear reducer, thereby achieving uniform welding. This mechanism can adjust the angle, speed and center position of the swing according to the requirements of the welding process to adapt to different welding needs. Through programming control, the pendulum mechanism can accurately repeat the welding action to ensure the consistency of the welding quality.

[0004] However, the existing pendulum mechanism cannot well adapt to welding of elliptical or special-shaped products, because its design is often based on simple reciprocating motion and lacks adaptability to complex trajectories. In addition, the adjustment of the pendulum mechanism is usually cumbersome, and once the swing amplitude or speed needs to be changed, professional personnel may need to adjust it. In the welding process, if the welding speed or swing amplitude needs to be changed, the lack of flexibility of this mechanism may affect the welding quality and efficiency.
