The invention discloses a steel structure
welding guiding and positioning device, which relates to the technical field of steel structure
processing, and comprises a main body supporting frame, a workpiece dynamic limiting and conveying unit and a self-centering clamping and
welding module, and is matched with a guiding and feeding mechanism, a self-adaptive reducing connecting cabin and a multi-dimensional self-adaptive
welding gun executing mechanism to realize integrated welding and positioning. The main
body frame serves as a bearing foundation, the guide feeding mechanism drives guide rollers to stably feed through meshing transmission, the stability is improved through a
surface pattern sleeve, the dynamic limiting unit forms bidirectional limiting through an adjusting screw, a cross connecting rod and a driving limiting shaft rod and is adaptive to different workpieces, and the self-centering clamping module adjusts the distance through
gear transmission. A profiling clamping jaw is matched with a spring to achieve self-adaptive clamping, an anti-vibration pad protects a workpiece, a self-adaptive connecting cabin adjusts the height of a welding gun, a multi-dimensional welding gun mechanism achieves accurate alignment in the X direction and the Z direction, all parts of the device are in cooperative linkage, the welding positioning accuracy and adaptability are improved, and the welding quality of a steel structure is guaranteed.
