[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Specific examples are given below.

[0025] Please refer to Figure 1 - Figure 4, the present utility model provides a steel welding positioning device, including a support leg 1; an angle adjustment ring 11 is fixedly connected to the end of the support leg 1; a moving ring 14 is slidably connected to the middle of the angle adjustment ring 11; a connecting rod 12 is provided on the side wall of the support leg 1; a first fixed pipe 13 is fixedly connected to the end of the connecting rod 12; a second fixed pipe 15 is fixedly connected to the middle of the moving ring 14; a first fixed screw 16 is threadedly connected to the tops of the first fixed pipe 13 and the second fixed pipe 15; a first rotating rod 17 is slidably connected to the end of the first fixed screw 16; an arc-shaped fixing plate 18 is rotatably connected to the end of the first fixed screw 16. During work, when welding a pipeline, since the pipeline is circular, at the bending part of the pipeline, an elbow needs to be used to connect the pipeline. According to different requirements, the angles of the elbows are also different. Therefore, the staff needs to weld the elbow at one end of the pipeline and then weld the other end from the elbow to complete the welding of the pipeline. During welding, the welds need to be flush, and since the pipeline is circular, it is not easy to fix, thus making it inconvenient for the staff to weld. Through the provided fixing device, the staff fixes the elbow in the second fixed pipe 15 and welds the pipeline inside the first fixed pipe 13, or vice versa. By rotating the first fixed screw 16, the arc-shaped fixing plate 18 is made to approach the pipeline, thereby fixing the pipeline or elbow inside the first fixed pipe 13 or the second fixed pipe 15. The first fixed pipe 13 and the second fixed pipe 15 are at the same height. According to the different angles of the elbow, the position of the moving ring 14 is adjusted, and then the elbow and the pipeline are aligned to start welding. The provided elbow welding device effectively facilitates the welding of the pipeline and the elbow by the staff, and thus effectively facilitates the fixing of the pipeline and the elbow by the staff, thereby effectively improving the convenience of the device and thus effectively improving the welding effect.

[0026] Further, as Figure 1 - Figure 4 shown, a plurality of fixing columns 2 are fixedly connected to the side wall of the moving ring 14; a threaded pipe 21 is fixedly connected to the end of the fixing column 2; a second fixed screw 22 is threadedly connected to the middle of the threaded pipe 21; a second rotating rod 23 is slidably connected to the end of the second fixed screw 22; a fixing piece 24 is rotatably connected to the end of the second fixed screw 22. During work, after moving the moving ring 14 to an appropriate angle of the elbow, the staff holds the second rotating rod 23 and rotates the second fixed screw 22, so that the fixing piece 24 presses against the angle adjustment ring 11, thereby fixing the moving ring 14 at the current position, thus fixing the moving ring 14. This effectively reduces the situation where the moving ring 14 displaces during welding by the staff. After use, the staff rotates the second fixed screw 22 in the reverse direction to make the fixing piece 24 away from the angle adjustment ring 11, and then the moving ring 14 can be moved. By fixing the moving ring 14, the fixing effect of the device is effectively increased, and the situation where the moving ring 14 displaces during welding is reduced, thereby effectively improving the stability of the device.

[0027] Further, as Figure 1 - Figure 3 shown, a plurality of scale grooves 31 are formed in the middle of the angle adjustment ring 11; the scale grooves 31 are arranged in an annular array; through holes 3 are formed in the side wall of the moving ring 14. During operation, when adjusting the angle between the first fixed pipe 13 and the second fixed pipe 15, through the scale grooves 31 provided on the surface of the support leg 1, the staff can easily adjust the first fixed pipe 13 and the second fixed pipe 15 to the angles required for elbow welding, thus effectively facilitating the adjustment of the equipment by the staff and further effectively increasing the convenience of the equipment.

[0028] Further, as Figure 1 - Figure 3 shown, a connecting plate 4 is fixedly connected to the side wall of the support leg 1; a pipe grinding cone 41 is fixedly connected to the top of the connecting plate 4; the pipe grinding cone 41 is conical. During operation, when welding a pipe, burrs will appear on the weld joint of the pipe after cutting. Through the provided pipe grinding cone 41, the staff inserts the weld joint of the pipe onto the pipe grinding cone 41 and then rotates the pipe to grind off the burrs at the pipe opening, so as to facilitate the welding of the pipe and the elbow by the staff, reduce the gap between the pipe and the elbow, and improve the welding effect.

[0029] Further, as Figure 2 and Figure 3 shown, a groove 5 is formed at the bottom of the support leg 1; a groove 5 is formed at the bottom of the connecting plate 4; a magnet 51 is provided on the inner side wall of the groove 5; the magnet 51 is fixedly connected to the inner side wall of the groove 5. During operation, through the magnet 51 provided at the bottom of the equipment, when using the equipment, the groove 5 can effectively adsorb on the metal welding table, thereby effectively increasing the fixing effect of the equipment and reducing the displacement of the equipment during welding.

[0030] Further, as Figure 1 - Figure 3 shown, a threaded hole 6 is formed in the middle of the connecting rod 12; a clamping groove is formed in the middle of the connecting rod 12; the inner side wall of the clamping groove is slidably connected to the connecting rod 12; a threaded hole 6 is formed at the end of the connecting rod 12; a fixing bolt 61 is threadedly connected to the inner side wall of the threaded hole 6. During operation, through the detachable setting of the connecting rod 12, when the pipe welding is completed, the staff separates the connecting rod 12 from the support leg 1 and then rotates the connecting rod 12 to the top of the pipe, so as to take out the pipe from the second fixed pipe 15. Thus, it effectively facilitates the staff to take out the highly bent pipe from the equipment, and at the same time, the detachable setting is convenient for the staff to store the equipment, thereby effectively increasing the convenience of the equipment.

[0031] Further, as Figure 2 and Figure 3As shown, a rubber plate 7 is provided on the side wall of the arc-shaped fixing plate 18; the rubber plate 7 is fixedly connected to the side wall of the arc-shaped fixing plate 18. During operation, by means of the rubber plate 7 provided on the side wall of the arc-shaped fixing plate 18, when using the arc-shaped fixing plate 18 to fix the pipeline to be welded, the friction force between the rubber plate 7 and the pipeline is effectively increased through the provided rubber plate 7, thereby effectively improving the fixing effect of the first rotating rod 17 on the pipeline, further reducing the situation of the pipeline shaking and displacing during the welding operation by the staff, and at the same time effectively protecting the pipeline and reducing the occurrence of scratches on the pipeline surface.

[0032] Working principle: When welding pipes, since the pipes are circular, elbows are required at the bends of the pipes to connect them. Depending on the requirements, the angles of the elbows are different. Therefore, workers need to weld the elbow to one end of the pipe and then weld the other end from the elbow to complete the welding of the pipe. During welding, the welds need to be flush. Also, because the pipes are circular, they are not easy to fix, which makes it inconvenient for workers to weld. Through the set fixing device, workers fix the elbow inside the second fixing pipe 15 and weld the pipe inside the first fixing pipe 13, or vice versa. By rotating the first fixing screw 16, the arc-shaped fixing plate 18 approaches the pipe, and then the pipe or elbow is fixed inside the first fixing pipe 13 or the second fixing pipe 15. The first fixing pipe 13 and the second fixing pipe 15 are at the same height. According to the different angles of the elbow, the position of the moving ring 14 is adjusted, and then the elbow is aligned with the pipe to start welding. The set elbow welding device effectively facilitates the welding of the pipe and the elbow by workers, and thus effectively facilitates the fixing of the pipe and the elbow by workers, thereby effectively improving the convenience of the equipment and thus effectively improving the welding effect. After moving the moving ring 14 to the appropriate angle of the elbow, the worker holds the second rotating rod 23 and rotates the second fixing screw 22, so that the fixing piece 24 presses the angle adjusting ring 11, thereby fixing the moving ring 14 in the current position, thus fixing the moving ring 14, which effectively reduces the displacement of the moving ring 14 during welding by workers. After use, the worker rotates the second fixing screw 22 in the reverse direction to make the fixing piece 24 away from the angle adjusting ring 11, and then the moving ring 14 can be moved. By fixing the moving ring 14, the fixing effect of the equipment is effectively increased, and the displacement of the moving ring 14 during welding is reduced, thereby effectively improving the stability of the equipment. When adjusting the angle between the first fixing pipe 13 and the second fixing pipe 15, through the scale groove 31 provided on the surface of the support leg 1, the worker can easily adjust the first fixing pipe 13 and the second fixing pipe 15 to the angles required for elbow welding, thereby effectively facilitating the adjustment of the equipment by workers and thus effectively increasing the convenience of the equipment. When welding the pipe, burrs will appear at the welded joint of the pipe after cutting. Through the set pipe grinding cone 41, the worker inserts the welded joint of the pipe onto the pipe grinding cone 41 and then rotates the pipe to grind off the burrs at the pipe opening, thereby facilitating the welding of the pipe and the elbow by workers, reducing the gap between the pipe and the elbow, and improving the welding effect. By setting the magnet 51 at the bottom of the equipment, when using the equipment, the groove 5 can effectively adsorb on the metal welding table, thereby effectively increasing the fixing effect of the equipment and reducing the displacement of the equipment during welding. Through the detachable setting of the connecting rod 12, when the pipe welding is completed, the worker separates the connecting rod 12 from the support leg 1 and then rotates the connecting rod 12 to the top of the pipe, and thus the pipe can be taken out from the second fixing pipe 15.Furthermore, it effectively facilitates the staff to take out the bent pipeline from the equipment. At the same time, the detachable setting is convenient for the staff to store the equipment, thereby effectively increasing the convenience of the equipment. By arranging the rubber plate 7 on the side wall of the arc-shaped fixing plate 18, when using the arc-shaped fixing plate 18 to fix the pipeline to be welded, through the arranged rubber plate 7, the friction force between the rubber plate 7 and the pipeline is effectively increased, thereby effectively improving the fixing effect of the first rotating rod 17 on the pipeline, further reducing the situation of shaking and displacement of the pipeline when the staff welds the pipeline, and at the same time effectively protecting the pipeline and reducing the situation of scratches on the pipeline surface.
