The working process of the invention is as follows:
Before welding, the weld joint positioning mechanism 2 is in an upturning state above the round tube supporting rod 1, the round tube limiting and pushing-out mechanism 7 is in an extending state at the rear end of the round tube supporting rod 1, the round tube positioning mechanism 8 is in an upturning opening state at the front end of the round tube supporting rod 1, and the belt opening and closing mechanism 6 drives the belt tightening mechanisms 5 at two sides to be in an opening state.
When welding is needed, firstly, the welding seam positioning mechanism 2 starts to work, the welding seam positioning plate 201 is turned down and inserted into the groove 101 on the upper edge of the circular tube supporting rod 1, so that the welding seam of the circular tube is positioned, according to the length of the circular tube 11, the circular tube limiting and pushing mechanism 7 starts to work, then the welding seam of the circular tube 11 to be welded is aligned with the welding seam positioning plate 201, then the circular tube positioning mechanism 8 starts to work, the circular tube positioning plate 801 is turned down and covers the front end of the circular tube supporting rod 1, and the circular tube 11 on the circular tube supporting rod 1 is placed in a holding action cavity formed by the middle part of the holding belt 4; and then the circular tube limiting push-out plate 702 extends forwards and pushes the circular tube 11 to move forwards along the circular tube supporting rod 1 until the front end of the circular tube 11 is contacted with the circular tube positioning plate 801, so that the circular tube 11 is positioned forwards and backwards.
After the round tube 11 is positioned, the round tube pre-pressing mechanism 3 positioned at one side of the round tube supporting rod 1 starts to work firstly, and simultaneously the air bag 301 is inflated to drive the round tube pre-pressing plate 303 to press down, so that one side edge of a welding line of the round tube 11 is pressed firstly, then the welding line positioning mechanism 2 starts to work, the welding line positioning plate 201 is turned up and is withdrawn from the groove 101 on the upper edge of the round tube supporting rod 1 to vacate a welding position, then the round tube pre-pressing mechanism 3 positioned at the other side of the round tube supporting rod 1 starts to work, and simultaneously the air bag 301 is inflated to drive the round tube pre-pressing plate 303 to press down, so that the other side edge of the welding line of the round tube 11 is pressed down, and at the moment, the left side edge and the right side edge of the welding line of the round tube 11 are pre-pressed before welding.
After the round tube 11 is pre-pressed, the belt opening and closing mechanism 6 starts to work, meanwhile, the belt tightening mechanisms 5 on the two sides are driven to turn inwards, along with the gradual folding of the left and right belt tightening mechanisms 5, the round tube enclasping action cavity formed by the middle part of the enclasping belt 4 between the two belt tightening mechanisms 5 is gradually closed until the belt guide plate 505 of the belt tightening mechanism 5 drives the enclasping belt 4 to contact with the upper surfaces on the two sides of the round tube 11, meanwhile, the belt tightening mechanisms 5 on the two sides work simultaneously and wind the enclasping belt 4 from the two ends respectively, so that the inner diameter of the round tube enclasping action cavity is gradually reduced, at the moment, the round tube 11 is completely enclasped by the enclasping belt 4, and in the tightening process of the enclasping belt 4, the seam is smaller and smaller until the gap capable of meeting the requirement of laser welding is reached.
Finally, the laser welding head 10 welds the welding seam of the circular tube 11 under the drive of the laser welding head transfer mechanism 9, after the welding is completed, the laser welding head transfer mechanism 9 drives the laser welding head 10 to reset, the circular tube positioning mechanism 8 turns up the circular tube positioning plate 801, the positioning of the front end of the circular tube 11 is relieved, and the circular tube limiting and pushing mechanism 7 further extends the circular tube limiting pushing plate 702 forwards, so that the front end of the circular tube 11 is pushed out of the front end of the circular tube supporting rod 1 by a certain distance, and a worker can conveniently take down the welded circular tube 11.
The action process of the weld joint positioning mechanism 2 is as follows:
When the welding seam locating plate overturning cylinder 204 extends out, the welding seam locating plate bracket 202 drives the welding seam locating plate 201 to overturn downwards around the welding seam locating plate overturning shaft 205 and insert into the groove 101 of the circular tube supporting rod 1 for welding seam locating of the circular tube; when the welding seam locating plate overturning cylinder 204 is retracted, the welding seam locating plate bracket 202 drives the welding seam locating plate 201 to overturn upwards around the welding seam locating plate overturning shaft 205 and withdraw from the groove 101 of the round tube supporting rod 1, so that the welding seam locating of the round tube is relieved.
The round tube positioning mechanism 8 acts as follows:
When the round tube positioning plate overturning cylinder 805 extends, the round tube positioning plate overturning plate 803 drives the round tube positioning plate 801 and the round tube positioning plate clamping plate 802 to overturn downwards by rotating backwards around the round tube positioning plate overturning shaft 804, so that the round tube positioning plate 801 covers the front end of the round tube support rod 1, and the two round tube positioning plate clamping plates 802 are respectively clamped with the clamping columns 102 on the left side and the right side of the round tube support rod 1, thereby being used for positioning the front end of the round tube 11; when the round tube positioning plate overturning cylinder 805 retracts, the round tube positioning plate overturning plate 803 drives the round tube positioning plate 801 and the round tube positioning plate clamping plate 802 to overturn upwards by rotating forwards around the round tube positioning plate overturning shaft 804, so that the two round tube positioning plate clamping plates 802 are separated from the clamping columns 102 on the left side and the right side of the round tube support rod 1 respectively, and the round tube positioning plate 801 yields the position of the front end of the round tube support rod 1, so that the positioning of the front end of the round tube 11 is relieved.

When the circular tube limiting push-out plate sliding cylinder 704 stretches out before welding, the circular tube limiting push-out plate sliding assembly 703 drives the circular tube limiting push-out plate 702 to stretch out forwards through the circular tube limiting push-out plate mounting seat 705, so that the circular tube 11 on the circular tube supporting rod 1 is pushed to move forwards until the front end of the circular tube 11 is in contact with the circular tube positioning plate 801; when the round tube limit push-out plate sliding cylinder 704 stretches out after welding, the round tube limit push-out plate sliding assembly 703 drives the round tube limit push-out plate 702 to stretch out forwards through the round tube limit push-out plate mounting seat 705, so that the round tube 11 on the round tube support rod 1 is pushed to move forwards until the front end of the round tube 11 is pushed out of the front end of the round tube support rod 1 by a certain distance; when the round tube limiting push-out plate sliding cylinder 704 is fully retracted, the round tube limiting push-out plate sliding assembly 703 drives the round tube limiting push-out plate 702 to reset backwards through the round tube limiting push-out plate mounting seat 705, and the front end face of the round tube limiting push-out plate 702 is retracted to be flush with the rear end face of the round tube supporting rod 1.
The action process of the circular tube pre-pressing mechanism 3 is as follows:
When the air bag 301 is inflated, the circular tube prepressing plate connecting plate 304 drives the circular tube prepressing plate 303 to downwards press the upper surface of the welding seam edge of the circular tube 11 positioned on the circular tube supporting rod 1, so that welding seam edge prepressing is formed; when the air bag 301 leaks, the circular tube pre-pressing plate connecting plate 304 drives the circular tube pre-pressing plate 303 to be separated from the upper surface of the welding seam edge of the circular tube 11 positioned on the circular tube supporting rod 1 upwards under the action of the tension force of the reset tension spring 305, and the circular tube pre-pressing plate is in contact with the pre-pressing.

The belt tightening mechanism 5 operates as follows:
When the left belt tightening motor 502 and the right belt tightening motor 502 rotate positively, the left belt tightening motor 502 and the right belt tightening roller 501 are driven to start winding the left end and the right end of the enclasping belt 4, so that a round pipe enclasping cavity is formed in the middle of the enclasping belt 4 and is gradually tightened, and as the round pipe 11 is completely enclasped by the round pipe enclasping cavity of the enclasping belt 4, a welding seam of the round pipe 11 is extruded in the process of gradually tightening the round pipe enclasping cavity, so that a seam gap of the welding seam is smaller and smaller until reaching a gap capable of meeting the requirement of laser welding; on the contrary, when the left and right belt tightening motors 502 reversely rotate, the left and right belt tightening motors 502 drive the left and right belt tightening roller shafts 501 to start unwinding the left and right ends of the enclasping belt 4, so that the middle part of the enclasping belt 4 forms a circular pipe enclasping cavity to gradually relax, and further the entering and exiting of the circular pipe 11 can be met.
