Abstract

The invention provides a welding gun clamping swing mechanism, comprising a driving shaft and a driven shaft which are arranged on a swing frame; one end of the driving shaft is connected with a driving mechanism which consists of a motor and a reducer; a clamp is fixed on the driven shaft; the driving shaft and the driven shaft are provided with a ball holder; holes are distributed on the circumference of the ball holder; the holes on the circumference of the ball holder are internally provided with rolling balls; the ball holder of the driving shaft and that of the driven shaft are connected with each other by a ring-shaped steel belt; as the steel belt has high rigidity, the transmission precision is ensured; the transmission by steel belt increases the transmission distance and reduces the damage of the thermal radiation generated during the welding process on the motor and the reducer; meanwhile, the space structure near the welding gun is lessened, thus being beneficial for the welding gun to carry out the welding operation closely to the intersecting line of the connecting pipe.

Description

(1) Technical field

[0001] The invention relates to a welding mechanism, in particular to a swing mechanism for clamping a welding gun at the end joint of a tube-type welding robot. (2) Background technology

[0002] At present, for the end joint swing mode of the tube-type intersecting line welding robot, the swing of the welding gun is manually adjusted or the swing is directly clamped by a reducer. Based on the manual adjustment of the swing mechanism, the real-time operation of the workers is labor-intensive and inefficient. The manual fine-tuning of the swing angle will cause changes in the welding track, and the quality is difficult to guarantee; based on the swing mechanism directly clamped by the reducer, the motor and the reducer are separated The welding point is close, and the heat radiation generated by welding has a serious impact on the service life of the motor and the reducer. If the pipes are tightly distributed, the working space of the mechanism directly clampe...
