After the welding is completed, the worker only needs to take out the collection box and pour the welding slag into the trash can, thereby saving the worker's time in cleaning the welding slag.

[0014] The present invention has the following beneficial effects: When the gear train is moved, the gear train is moved along the guide rails, and the gear train is moved along the guide rails, and the gear train is moved along the guide rails, and the gear train is moved along the guide rails, and the gear train is moved along the guide rails, and the gear train is moved along the guide rails, and the gear train is moved along the guide rails, and the gear train is moved along the guide rails, and the gear train is moved along the guide rails, and the gear train is moved along the guide rails, and the gear train is moved along the guide rails, When the lower pressure plate moves, it pushes the force-bearing telescopic rod downward to retract, effectively supporting and fixing the two ends of the welded part through the two support plates, thereby separating the welded part from the placement frame and keeping the welded part in a suspended state, thereby reducing friction when the welding machine rotates and improving the welding quality.

[0016] The present invention provides a collecting mechanism. When the extrusion ring moves, it will squeeze the elastic frame. When the elastic frame is squeezed, the middle part will bend. When the middle part of the elastic frame bends, it will push the curved plate to move in the direction of approaching each other. When the curved plate moves, it will push the slag stop cover to move in the direction of approaching each other, thereby wrapping the part of the weld that needs to be welded. When the slag stop cover moves, it will drive the guide plate to move toward the weld. Since the surface of the guide plate is provided with a fitting hole, the inner wall of the fitting hole will contact the surface of the weld. At the same time, the slag stop cover will drive the automatic welding machine to move toward the weld, so that the output end of the automatic welding machine will contact the part of the weld that needs to be welded, and then start the power device to drive the rotating shaft. Rotation, when the shaft rotates, it will drive the slip ring to rotate, when the slip ring rotates, it will drive the connecting rod to rotate, when the connecting rod rotates, it will drive the support plate to rotate, when the support plate rotates, it will drive the welding part to rotate, and when the support plate rotates, it will drive the buffer telescopic rod to rotate on the inner wall of the annular groove. At the same time, the automatic welding machine is started to weld the welding parts. During the welding process of the automatic welding machine, welding slag will be generated and splashed around. At this time, the welding slag will be blocked by the guide plate, so that the welding slag will flow through the guide plate to the inner wall of the collection box for concentration, thereby blocking and collecting the welding slag generated by the automatic welding machine during the welding process. After welding, the worker only needs to take out the collection box and pour the welding slag into the trash can, thereby saving the worker's time in cleaning the welding slag.

The inner wall of 56 is concentrated, and the top of the inner wall of the slag shield 53 is fixedly connected with an automatic welding machine 57, so that the output end of the automatic welding machine 57 contacts the part of the weldment that needs to be welded, and then the power device 18 is started to drive the rotating shaft 19 to rotate. When the rotating shaft 19 rotates, it will drive the slip ring 20 to rotate. When the slip ring 20 rotates, it will drive the connecting rod 21 to rotate.

S2: When the placement rack 7 moves downward, it drives the lower pressure plate 6 to move downward. When the lower pressure plate 6 moves, it pushes the force-bearing telescopic rod 5 to retract downward, effectively supporting and fixing the two ends of the weldment through the two support plates 17, thereby separating the weldment from the placement rack 7 and keeping the weldment in a suspended state, thereby reducing friction during rotation welding of the weldment, thereby improving the quality of welding; S3: When the fixing ring 40 moves, due to its annular shape, the angle of the fixing ring 40 becomes smaller during the movement, thereby achieving the goal of fixing weldments of different diameters, improving welding efficiency. When the fixing ring 40 moves, it pushes the rotating wheel 41 to move toward each other so that it contacts the surface of the weldment, thereby achieving the effect of reducing friction during the rotation of the weldment; S4: At this time, the welding slag will be blocked by the guide plate 54, so that the welding slag will flow to the inner wall of the collection box 56 through the guide plate 54 and be concentrated, thereby blocking and collecting the welding slag generated by the automatic welding machine 57 during the welding process. After the welding is completed, the worker only needs to take out the collection box 56 and pour the welding slag into the trash can, thereby saving the worker's time in cleaning the welding slag.

9. The supporting method of the welding part supporting device for a welding robot according to claim 8, characterized in that: The following steps are involved: S1: When the bending plate 13 moves, it pushes the push rod 14 to move in a direction close to each other. When the push rod 14 moves, it pushes the sliding plate 15 to slide on the inner wall of the guide rail 2 in a direction close to each other. When the sliding plate 15 moves, it drives the buffer telescopic rod 16 to move in a direction close to each other. When the buffer telescopic rod 16 moves, it pushes the support plate 17 to move in a direction close to each other and contact with both ends of the weldment to support it. S2: When the placement rack 7 moves downward, it drives the lower pressure plate 6 to move downward. When the lower pressure plate 6 moves, it pushes the force-bearing telescopic rod 5 to retract downward, effectively supporting and fixing the two ends of the weldment through the two support plates 17, thereby separating the weldment from the placement rack 7 and keeping the weldment in a suspended state, thereby reducing friction during rotation welding of the weldment, thereby improving the quality of welding; S3: When the fixing ring 40 moves, due to its annular shape, the angle of the fixing ring 40 becomes smaller during the movement, thereby achieving the goal of fixing weldments of different diameters, improving welding efficiency. When the fixing ring 40 moves, it pushes the rotating wheel 41 to move toward each other so that it contacts the surface of the weldment, thereby achieving the effect of reducing friction during the rotation of the weldment; S4: At this time, the welding slag will be blocked by the guide plate 54, so that the welding slag will flow to the inner wall of the collection box 56 through the guide plate 54 and be concentrated, thereby blocking and collecting the welding slag generated by the automatic welding machine 57 during the welding process. After the welding is completed, the worker only needs to take out the collection box 56 and pour the welding slag into the trash can, thereby saving the worker's time in cleaning the welding slag.
