[0024] 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.
[0025] Please see Figure 1-5 The present invention provides the following technical solution:
[0026] A precision steel structure welding anti-deformation device includes a base 1, a first servo motor 2 fixedly connected to the right side of the base 1, a threaded rod 3 fixedly connected to the left side of the first servo motor 2, an adjusting block 4 threadedly connected to the surface of the threaded rod 3, a clamping assembly 5 fixedly connected to the adjusting block 4 and the top of the base 1, a first electric telescopic rod 6 fixedly connected inside the base 1, and an inner lining assembly 7 fixedly connected to the left side of the first electric telescopic rod 6.
[0027] The inner lining assembly 7 includes an adjustable bracket 701, with multiple telescopic rods 702 fixedly connected inside the adjustable bracket 701. A frame 703 is fixedly connected to the right side of the multiple telescopic rods 702. A second servo motor 704 is fixedly connected inside the frame 703. A placement block 705 is threadedly connected to the right side of the second servo motor 704. Two second electric telescopic rods 706 are fixedly connected inside the placement block 705. An inner lining plate 707 is fixedly connected to the opposite side of each of the two second electric telescopic rods 706. A protective pad 708 is fixedly connected to the opposite side of each of the two inner lining plates 707.
[0028] In this embodiment: A base 1 is placed on a horizontal working surface, with its interior and top used to install other functional components, such as a first servo motor 2 and a clamping assembly 5. The first servo motor 2, threaded rod 3, and adjusting block 4 are provided. The first servo motor 2 is activated, adjusting the threaded rod 3, which in turn adjusts the adjusting block 4. The adjusting block 4 then adjusts the position of the components inside the clamping assembly 5. The clamping assembly 5 limits the movement of the two steel structures for subsequent welding. A first electric telescopic rod 6 allows for the adjustment of the position of the inner lining assembly 7, which supports the inner walls of the two steel structures. An adjustable bracket 701 supports the multi-segment telescopic rod 702 and allows for height adjustment. The multi-segment telescopic rod 702 is connected to a frame 703 on the right side, which is extendable to accommodate different... The steel pipe, while providing some cushioning, is supported by a frame 703 and multiple telescopic rods 702. A second servo motor 704 is internally fixedly connected for installing and supporting subsequent components. The second servo motor 704 allows for angle adjustment of the placement block 705, facilitating the adjustment of the inner lining support position. The placement block 705 allows for the placement of two second electric telescopic rods 706. These two electric telescopic rods 706 allow for individual position adjustment of the two inner lining plates 707 as needed. An inner side plate, driven by the second electric telescopic rods 706, is fitted tightly against the inner wall of the steel pipe, providing internal support and preventing welding deformation. A protective pad 708 is fixedly connected to the surface, positioned on the opposite side of the inner lining plate 707. The protective pad 708, possibly made of flexible material, protects the inner wall of the steel pipe from damage and increases friction with the inner wall, making the support more stable.
[0029] Specifically, such as Figure 3 As shown, the clamping assembly 5 includes a first housing 501 and a second housing 502. The first housing 501 is fixedly connected to the top of the base 1, and the second housing 502 is bolted to the top of the adjusting block 4. The tops of the first housing 501 and the second housing 502 are both provided with sliding grooves 503. The rear side of the inner wall of the two sliding grooves 503 is rotatably connected with a bidirectional spiral rod 504. The surfaces of the two bidirectional spiral rods 504 are threaded with two sliding blocks 505. The tops of the two sliding blocks 505 are fixedly connected with limit plates 506.
[0030] Specifically, such as Figure 3 As shown, anti-slip plates 507 are fixedly connected to the opposite sides of the two limiting plates 506, and both anti-slip plates 507 are made of silicone.
[0031] Specifically, such as Figure 3 As shown, control blocks 508 are fixedly connected to the front side of both bidirectional screw rods 504, and both control blocks 508 are made of stainless steel.
[0032] In this embodiment: A first housing 501 and a second housing 502 are respectively fixed to the top of the base 1 and the adjusting block 4, forming the main frame 703 of the clamping structure. A sliding groove 503 is provided on the top for mounting a bidirectional spiral rod 504 and sliding blocks 505. The bidirectional spiral rod is rotatably connected to the rear side of the inner wall of the sliding groove 503, and two sliding blocks 505 are threaded onto its surface. By rotating the bidirectional spiral rod 504, the two sliding blocks 505 move in opposite directions, thereby causing the limiting plate 506 to clamp or release the steel pipe. The sliding blocks 505 are threadedly connected to the bidirectional spiral rod 504, and the top is fixed. The connecting limit plate 506 moves within the sliding groove 503 as the bidirectional spiral rod 504 rotates. The limit plate 506 is fixed to the top of the sliding block 505, and its opposite side is used to clamp the steel pipe. The movement of the sliding block 505 achieves the clamping or loosening of the steel pipe. The anti-slip plate 507, made of silicone, is fixed to the opposite side of the limit plate 506 to increase the friction with the surface of the steel pipe and prevent the steel pipe from sliding during clamping. The control block 508, made of stainless steel, is fixed to the front side of the bidirectional spiral rod 504 to facilitate manual rotation of the bidirectional spiral rod 504 and achieve adjustment of the limit plate 506.
[0033] Specifically, such as Figure 1 , Figure 3 As shown, both the first box 501 and the second box 502 have drawer slots 8 on their front sides, and tool boxes 9 are slidably connected inside the two drawer slots 8.
[0034] Specifically, such as Figure 1As shown, square plates 10 are fixedly connected to the top of the first box 501 and the second box 502. Slide grooves 11 are opened on the front side of the two square plates 10. Adjusting rods 12 are rotatably connected to the bottom of the inner wall of the two slide grooves 11. Sliding blocks 13 that cooperate with the slide grooves 11 are threadedly connected to the surface of the two adjusting rods 12. Top plates 14 are fixedly connected to the front side of the two sliding blocks 13.
[0035] In this embodiment: By setting a drawer slot 8 and a tool box 9, the drawer slot 8 is opened on the front side of the first box 501 and the second box 502. The tool box 9 is slidably connected in the drawer slot 8 for storing welding tools for easy access. By setting a square plate 10, a slide 11, an adjusting rod 12, a slider 13 and a top plate 14, the square plate 10 is fixed to the top of the first box 501 and the second box 502. The slide 11 is opened on the front side. The adjusting rod 12 is rotatably connected to the bottom of the inner wall of the slide 11. The slider 13 is threadedly connected to the adjusting rod 12. The top plate 14 is fixed in front of the slider 13 for further fixing the steel pipe and preventing it from moving up and down during welding. Rotating the adjusting rod 12 causes the slider 13 to move up and down in the slide 11, driving the top plate 14 to rise and fall, pressing the steel pipe tightly onto the clamping assembly 5, increasing the stability of the fixation.
[0036] Specifically, such as Figure 4 As shown, an auxiliary rod 15 is movably connected inside the base 1, and the auxiliary rod 15 is bolted to the right side of the adjustable bracket 701.
[0037] Specifically, such as Figure 5 As shown, the top of the first box 501 and the second box 502 are both provided with auxiliary grooves 16, and the bottom of the four limiting plates 506 are all fixedly connected with auxiliary blocks 17 that cooperate with the auxiliary grooves 16.
[0038] In this embodiment: by setting an auxiliary rod 15, which is movably connected inside the base 1 and bolted to the adjustable bracket 701 on the right side, it assists in supporting the inner lining assembly 7 and improves the stability of the inner lining assembly 7 during movement and operation. By setting an auxiliary groove 16 and an auxiliary block 17, the auxiliary groove 16 is opened at the top of the first housing 501 and the second housing 502, and the auxiliary block 17 is fixed at the bottom of the limiting plate 506 and works in conjunction with the auxiliary groove 16 to limit the movement direction of the limiting plate 506 and ensure that the limiting plate 506 moves smoothly during clamping.
[0039] Working principle: First, the steel pipe to be welded is placed on the clamping assembly 5 at the top of the base 1. The bidirectional spiral rod 504 is manually rotated by the control block 508, causing the sliding block 505 to move the limiting plate 506 to clamp the steel pipe. At the same time, the adjusting rod 12 is rotated to cause the slider 13 to move the top plate 14 down, further pressing and fixing the steel pipe. Then, the first servo motor 2 is started, which drives the threaded rod 3 to rotate, causing the adjusting block 4 and the second housing 502 to move to adjust the docking position of the two steel pipes. Subsequently, the first electric telescopic rod 6 extends, pushing the adjustable bracket 701 and the multi-segment telescopic rod 702 in the inner liner assembly 7 into the steel pipe. The second servo motor 6 extends the first electric telescopic rod 6 to extend the second electric telescopic rod 702 into the steel pipe. The machine 704 drives the placement block 705 to move to the appropriate position, and then pushes the inner liner plate 707 to open through the second electric telescopic rod 706, so that the protective pad 708 is tightly attached to the inner wall of the steel pipe to provide internal support. During the welding process, the multi-segment telescopic rod 702 can adapt to the length of the steel pipe and buffer thermal stress. The inner liner plate 707 supports the weld area through the protective pad 708 to reduce welding deformation. The auxiliary rod 15 enhances the stability of the inner liner component 7, ensuring that the position of the steel pipe is fixed and the internal support is uniform throughout the welding process. This effectively solves the problems of poor weld formation and thermal stress concentration caused by lack of support in the prior art, and ensures welding accuracy and structural stability.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
