The extension frame 4 serves to fix the plate frame 5. Both ends of the plate frame 5 are obliquely fixedly installed with inclined frames 20. The two inclined frames 20 are symmetrically arranged. The inclined frames 20 can initially limit the two aluminum alloy profiles 35 to form a V shape. A space is left between the ends of the two oblique frames 20, so that the joints of the two aluminum alloy profiles 35 can be fully exposed to be welded. Two supporting ears 21 are symmetrically fixedly installed near the middle of the lower end of the oblique frame 20, and the supporting ears 21 serve to support the aluminum alloy profiles 35.

[0031] The front and rear ends of the extending frame 4 are extended with reinforcement frames 34, and the ends of the reinforcement frames 34 are fixed to the plate frame 5.

[0032] A No. 1 limiting ear 18 is extended from the upper and lower ends of the No. 1 square ejector pin 17. The No. 1 limiting ear 18 can limit the extension distance of the No. 1 square ejector pin 17 to prevent the No. 1 square ejector pin 17 from extending too long and hindering the aluminum alloy profile 35 from being placed between the two inclined frames 20. A No. 2 angle ear 22 is fixedly installed at both ends of the inclined frame 20. A No. 2 tightening spring 23 is fixedly installed at the end of the No. 2 angle ear 22.

At this time, the two ends of the inclined frames 20 are fitted to the outer sides of the aluminum alloy profiles 35 to initially limit the two aluminum alloy profiles 35 to form a V shape. At the same time, the No. 1 tensioning spring 16 and the No. 2 tensioning spring 23 are deformed under the support of the inserted aluminum alloy profile 35, and then a reaction force is generated to push the expansion seat 19 and the No. 2 square push pin 25, so that the No. 2 square push pin 25 and the expansion seat 19 can push the aluminum alloy profile 35 from the outer side of the aluminum alloy profile 35, so that the joints of the two aluminum alloy profiles 35 can be tightly fitted together, and then the servo motor 6 works to drive the threaded rod 8 to rotate, so that the No. 1 concave gun holder 9 tightened on the threaded rod 8 can slide on the guide rod 7 to move. , the moving No. 1 concave gun rack 9 drives the two No. 1 welding guns 26 to move synchronously. At this time, the top gun wheel 30 rolls on the horizontal section of the gun lifting guide rail 32, so that the two No. 1 welding guns 26 that have moved are used to weld the upper and lower seams of the aluminum alloy profile 35. When the welding of the upper and lower seams is completed, the top gun wheel 30 just rolls to the inclined surface of the gun lifting guide rail 32, and then the No. 1 concave gun rack 9 continues to move. At this time, the top gun wheel 30 rolls on the inclined surface of the gun lifting guide rail 32 to push the No. 2 concave gun rack 31. At the same time, the guide column 10 slides in the guide shell 3 to guide the No. 2 concave gun rack 31, so that the two No. 2 welding guns 27 on the No. 2 concave gun rack 31 can move vertically upward to weld the seams on both sides of the aluminum alloy profile 35, so that the seams around the aluminum alloy profile 35 are fully welded at one time.
