DETAILED DESCRIPTION OF THE INVENTION

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1-2 shown, an auxiliary tool for perpendicular welding of a steel pipe 3 and a plate 2 includes a welding table 1 for placing the plate 2. The plate 2 is flatly placed on the upper end of the welding table 1. Above the welding table 1, a right-angle frame 4 for fixing the steel pipe 3 is connected by a bracket. The right-angle frame 4 is perpendicular to the welding table 1. The steel pipe 3 leans against the inner corner of the right-angle frame 4. At both ends of the right-angle frame 4, there are first threaded rods 5 for fixing the steel pipe 3. The first threaded rods 5 press the steel pipe 3 against the right-angle frame 4 to ensure perpendicularity between the steel pipe 3 and the plate 2. At both ends of the right-angle frame 4, support arms 403 are connected by rotating shafts. The support arms 403 can rotate 360°. At the end of the support arm 403, a second threaded rod 6 for pressing the plate 2 is connected. The position where the second threaded rod 6 presses down can be adjusted through the support arm 403 to press and fix the plate 2.

[0024] The bracket includes a vertical column 101 and a cross beam 102 that are perpendicularly connected. The vertical column 101 is connected to the welding table 1. One end of the cross beam 102 is connected to the vertical column 101, and the other end of the cross beam 102 is connected to the right-angle frame 4. The distance between the vertical column 101 and the right-angle frame 4 can be increased through the cross beam 102 to ensure the flexibility of the placement position of the plate 2.

[0025] As Figure 3 shown, at both ends of the right-angle frame 4, there are first support blocks 402. The first threaded rods 5 are in threaded cooperation with the first support blocks 402. At both ends of the first threaded rod 5, there are respectively a first handle 502 and a top block 501. An anti-slip pad is provided on the side wall of the top block 501 to prevent damage to the side wall of the steel pipe 3.

[0026] To prevent the top block 501 from rotating, as Figure 4 shown, a guide rod 401 is provided inside the right-angle frame 4. At the end of the top block 501, there is a sliding sleeve 503 that is slidably matched with the guide rod 401. The first threaded rod 5 is rotatably connected to the top block 501.

[0027] At both ends of the second threaded rod 6, there are respectively a second handle 601 and a pressing block 602. An anti-slip pad is provided at the bottom of the pressing block 602 to prevent damage to the pressing plate.

[0028] In use, first, the steel pipe 3 is fixed on the right-angle frame 4 through the first threaded rod 5. The distance between the bottom of the steel pipe 3 and the welding table 1 is greater than the thickness of the plate 2. The plate 2 is placed on the welding table 1, and the position of the plate 2 is adjusted so that the steel pipe 3 is aligned with the welding position of the plate 2. The plate 2 is pressed and fixed through the second threaded rod 6. The first threaded rod 5 is loosened, and the steel pipe 3 is pressed on the upper end of the plate 2 and the steel pipe 3 is fixed again. After the steel pipe 3 and the plate 2 are vertically butted, welding is carried out.
