[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 An embodiment of this utility model provides a welding fixing device for welded pipe production, comprising a water tank 1, with guide rods 3 fixedly connected to both the left and right sides inside the water tank 1, and first guide rings 4 slidably connected to the outer walls of the guide rods 3, with bolts 5 threadedly connected to the front end of the first guide rings 4, a fixing ring 6 fixedly connected to the outer side of the first guide rings 4, a rotating ring 7 rotatably connected to the inner wall of the fixing ring 6, a silicone block 11 fixedly connected to the inner wall of the rotating ring 7, a first screw 9 threadedly connected to the upper end of the rotating ring 7, a connecting ring 24 rotatably connected to the lower end of the first screw 9, a pressure plate 8 fixedly connected to the bottom end of the connecting ring 24, and a handwheel 10 fixedly connected to the top end of the first screw 9.

[0025] The guide rod 3 provides a sliding track for the first guide ring 4. By pushing the first guide ring 4 and tightening the bolt 5, the horizontal position of the fixed ring 6 can be flexibly adjusted and locked. When the welded pipe is placed into the rotating ring 7, the protrusion on the inner wall of the fixed ring 6 matches the groove of the rotating ring 7 and can rotate 360° to adapt to different welding angles of the welded pipe. Rotating the handwheel 10 drives the first screw 9 to move the pressure plate 8 downward in conjunction with the connecting ring 24. This, together with the silicone block 11 on the inner wall of the rotating ring 7, achieves radial clamping of the welded pipe, forming a three-dimensional fixing structure that is "horizontally adjustable, angle-adaptable, and radially tight". This structure can adapt to the needs of welded pipes of different lengths and welding processes through horizontal sliding and angle rotation, without the need for frequent clamping adjustments. It can also avoid damage to the surface of the welded pipe by using the flexible contact of the silicone block 11, while enhancing clamping stability and suppressing displacement caused by welding vibration. Operationally, the handwheel 10 and the first screw 9 drive the adjustment with effortless ease and have a self-locking function to prevent loosening. A single person can complete the clamping and positioning, reducing manual labor intensity.

[0026] Reference Figures 2-4 The water tank 1 has a second screw 14 rotatably connected to both ends. A crossbar 15 is rotatably connected to one end of the second screw 14. The front and rear ends of the crossbar 15 are fixedly connected to the inner side of the water tank 1. A rocker arm 13 is fixedly connected to the opposite end of the second screw 14. A second fixing block 22 is threadedly connected to the outer side of the second screw 14. The upper end of the second fixing block 22 is fixedly connected to the lower side of the fixing ring 6. A second guide ring 25 is horizontally slidably connected to the outer side of the guide rod 3. A support plate 12 is fixedly connected to the outer side of the second guide ring 25. A silicone block 11 is fixedly connected to the inner wall of the support plate 12. The water tank 1 has a front inner side... The third screw 21 is rotatably connected to the water tank 1. The outer wall of the third screw 21 is threadedly connected to the third fixing block 26. The slide rod 20 is fixedly connected to the rear side of the water tank 1. The outer wall of the slide rod 20 is slidably connected to the first fixing block 19. The scraper 18 is fixedly connected to the opposite side of the first fixing block 19 and the third fixing block 26. The left side of the water tank 1 is fixedly connected to the tightening component 16. The inner wall of the tightening component 16 is fixedly connected to the motor 17. The drive end of the motor 17 is fixedly connected to the left end of the third screw 21. The four corners of the bottom end of the water tank 1 are fixedly connected to the casters 2 respectively. The right end of the water tank 1 is provided with a drain plug 23.

[0027] Rotating the rocker arm 13 on the left and right sides of the water tank 1 drives the second screw 14 to cooperate with the second fixing block 22, causing the fixing ring 6 to slide horizontally along the guide rod 3, achieving precise adjustment of the welded pipe position and flexibly adjusting the horizontal spacing between welded pipes to adapt to different welding needs. Starting the motor 17 drives the third screw 21 to rotate, causing the third fixing block 26, the first fixing block 19, and the scraper 18 to move along the slide rod 20 along the bottom of the water tank 1, automatically cleaning the welding slag, simplifying the equipment maintenance process, effectively reducing the labor intensity of manual cleaning, and the casters 2 give the device mobility, eliminating the need for additional equipment handling. The widened design of the drain plug 23 at the right end of the water tank 1 also improves the convenience of sewage discharge.

[0028] Working principle: The welded pipe is placed inside the rotating ring 7. Turning the handwheel 10 causes the pressure plate 8 to move downwards via the first screw 9 and connecting ring 24, which, together with the silicone block 11 on the inner wall of the rotating ring 7, clamps the welded pipe. Turning the rocker arm 13 causes the second screw 14 to rotate. The second screw 14, together with the second fixing block 22, causes the fixing ring 6 to move horizontally along the guide rod 3, thereby adjusting the position of the welded pipe. Tightening the bolt 5 fixes the first guide ring 4 to determine the welding position of the welded pipe. The support plate 12 and silicone block 11 on the outer side of the second guide ring 25 provide auxiliary support for the welded pipe from both sides. The rotating ring 7 can achieve 360° rotation. The rotation facilitates the integral welding of the pipe. Water is added to the water tank 1 to a suitable height, and the welding slag falls into the water and cools quickly. The motor 17 is started, and the motor 17 drives the third screw 21 to rotate, so that the third fixed block 26 drives the scraper 18 and the first fixed block 19 to slide along the slide rod 20 to guide the scraper 18. The scraper 18 cleans the welding slag and impurities in the water tank 1. The upper end of the scraper 18 is designed as a hollow plate to prevent water from easily overflowing when scraping the welding slag and impurities. After the welding slag and impurities are scraped off, the drain plug 23 is opened, and the sewage and welding slag and impurities can be discharged through the drain.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
