For example, steel pipes are ubiquitous in daily life, used for various industrial functions and residential drainage systems. With the continuous improvement of steelmaking technology, the hardness and toughness of thin-walled steel pipes are increasing.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please see Figure 1-6 As shown, the present invention is a welding device for steel structure processing, including a support base 1, with internal welding mechanisms 2 symmetrically installed on both sides of the support base 1, an external welding mechanism 3 provided at the top center of the support base 1, clamping mechanisms 5 installed on both sides of the external welding mechanism 3, and a flipping mechanism 4 provided on the outer side of each of the two clamping mechanisms 5.

[0029] The external welding mechanism 3 includes two symmetrically arranged splicing seats 31. The two splicing seats 31 can be moved by a cylinder, lead screw, or motor. The splicing seats 31 are slidably connected to the support seat 1. A semi-circular guide rail 33 is fixedly installed on the splicing seat 31. An arc-shaped toothed ring 34 is slidably connected to the semi-circular guide rail 33. The arc-shaped toothed ring 34 is meshed with a gear 32 on the splicing seat 31. The gear 32 is driven by a motor. A retractable welding torch 36 is fixedly installed on the arc-shaped toothed ring 34 to facilitate welding of pipes of different diameters. The two arc-shaped toothed rings 34 are snap-fitted together.

[0030] One of the arc-shaped toothed rings 34 has insertion slots 38 on both sides, and the other arc-shaped toothed ring 34 has insertion blocks 35 on both sides. The insertion blocks 35 are adapted to the insertion slots 38. The insertion blocks 35 and the insertion slots 38 facilitate the splicing of the two arc-shaped toothed rings 34, enabling rotation and welding.

[0031] A cylinder 39 is also fixedly installed on the splicing base 31. A limiting plate 37 is fixedly installed on the piston rod of the cylinder 39. The limiting plate 37 is adapted to the arc-shaped toothed ring 34. When not in use, the cylinder 39 is started to push the limiting plate 37 into the arc-shaped toothed ring 34 to limit its movement and prevent the arc-shaped toothed ring 34 from rotating when not in use.

[0032] After the two pipes are connected, the two splicing seats 31 are driven to join together. At this time, the two arc-shaped toothed rings 34 also join together. Then, the cylinder 39 is activated, which drives the limit plate 37 to retract, allowing the arc-shaped toothed rings 34 to rotate. The welding torch 36 is adjusted to contact the pipe surface. The gear 32 is activated, which drives the arc-shaped toothed rings 34 to rotate, and the welding torch 36 welds the surface of the pipe. This allows for comprehensive welding and can weld pipes of different diameters. After welding is completed, the two splicing seats 31 separate, making it easy to remove the welded pipe.

[0033] The internal welding mechanism 2 includes an L-shaped plate 21 slidably connected to the support base 1. The L-shaped plate 21 is driven to move by a cylinder, screw, or motor. A rotary motor 22 is fixedly installed on the L-shaped plate 21. A pulley 23 is sleeved on the output shaft of the rotary motor 22. The pulley 23 is connected to a pulley 24 via a belt. The pulley 24 is fixedly installed on a transmission shaft 25. The transmission shaft 25 is rotatably mounted on the L-shaped plate 21 and passes through the L-shaped plate 21 to connect with a cylinder 211. A retractable welding torch 210 is fixedly installed on the piston rod of the cylinder 211 to facilitate welding of the inner walls of pipes of different diameters.

[0034] The transmission shaft 25 is sleeved with an outer cylinder 213. A frustum-shaped disk 214 is fixedly installed at one end of the outer cylinder 213. The frustum-shaped disk 214 has multiple ventilation holes for ventilation welding. Multiple cylinders 26 are installed at equal intervals on the outer surface of the outer cylinder 213. A moving block 27 is fixedly installed on the piston rod of the cylinder 26. The moving block 27 is movably connected to the support plate 29 through a movable rod 28. The bottom of the support plate 29 is also movably connected to the outer cylinder 213 through multiple movable rods 212.

[0035] Two L-shaped plates 21 move towards the center, and welding torch 210 is inserted into the pipe. When the frustum-shaped disc 214 contacts the pipe, it pushes the pipe to move synchronously, thus connecting the two pipes. Then, cylinder 26 is activated, which pushes the support plate 29 to contact the inner wall of the pipe via moving block 27 and movable rod 28, facilitating support for pipes of different diameters from the inner wall. Simultaneously, cylinder 211 is activated, moving welding torch 210 to the designated position. Then, rotary motor 22 is activated, which drives drive shaft 25 to rotate via pulleys 23 and 24. Drive shaft 25 drives cylinder 211 and welding torch 210 to rotate and weld the inner wall of the pipe. This structure works in conjunction with the external welding mechanism 3 to facilitate welding of pipes of different diameters from both inside and outside, resulting in better welding effects. The internal welding mechanism 2 on the right can replace welding torch 210 with a lighting lamp for illumination.

[0036] The clamping mechanism 5 is fixedly installed on the Y-shaped plate 51 on the support base 1. Support wheels 52 are provided at both ends of the top of the Y-shaped plate 51. A cylinder 53 is provided on one side of the Y-shaped plate 51. A flip plate 54 is movably connected to the piston rod of the cylinder 53. A pressing plate 55 is installed on the flip plate 54.

[0037] The two pipes are placed on the Y-shaped plate 51 by a person or a robot. After the two pipes are connected, the cylinder 4 53 is activated, and the clamping plate 55 is driven by the flipping plate 54 to clamp them from the outside. The internal welding mechanism 2 provides internal support to prevent the pipes from shaking during the welding process, which would result in poor welding effect.

[0038] Example 2

[0039] Based on Example 1, please refer to Figure 4 and 6As shown, the flipping mechanism 4 includes two flipping seats 41 slidably mounted on the support base 1. The flipping seats 41 are driven horizontally by a cylinder, lead screw, or motor to prevent contact with the external welding mechanism 3 during flipping. Each of the two flipping seats 41 has an arc-shaped guide rail 44 on its inner side, and an arc-shaped flipping plate 43 is slidably connected between the two arc-shaped guide rails 44. The length of the arc-shaped guide rail 44 is greater than that of the arc-shaped flipping plate 43 to ensure the stability of its rotation. The outer circumference of the arc-shaped flipping plate 43 is evenly spaced with... Multiple teeth 47; a lifting seat 45 is fixedly installed on the top of the arc-shaped flip plate 43; a lifting cylinder is provided on the top of the lifting seat 45; an arc-shaped placement plate 46 is fixedly installed on the piston rod of the lifting cylinder; after welding is completed, it drives the pipe to move upward, thereby facilitating subsequent movement and flipping; two gears 42 are symmetrically installed on the flip seat 41; the gears 42 are driven by a motor; the two gears 42 can also be connected by a synchronous belt and a belt, so that the two gears 42 rotate synchronously; the gears 42 mesh with the teeth 47.

[0040] A triangular inclined seat 6 is provided on one side of the support base 1. An inclined discharge channel 61 is provided inside the triangular inclined seat 6. Multiple elastic elements 62 of different heights are provided on the inner wall of the discharge channel 61. The elastic elements 62 are springs. An inclined plate 63 is fixedly installed at the bottom of the elastic elements 62.

[0041] A push cylinder 66 is fixedly installed inside the triangular inclined seat 6. A push-pull plate 64 is fixedly installed on the piston rod of the push cylinder 66. Multiple placement slots 65 are evenly opened on the push-pull plate 64. A buffer pad is provided on the placement slot 65. When the push cylinder 66 is activated, the push-pull plate 64 is moved, so that the sliding pipes can be placed one by one on the placement slots 65 to avoid collisions between the pipes.

[0042] First, the arc-shaped placement plate 46 is used to support the placement of the pipes. After welding is completed, the clamping mechanism 5 and the internal welding mechanism 2 are released, and the internal welding mechanism 2 and the external welding mechanism 3 are driven to move to both sides. Then, the lifting seat 45 drives the pipes to move upward and drives the flipping seat 41 to move horizontally a certain distance to avoid contact with the external welding mechanism 3 during the flipping process. Then, the gear 42 is started to rotate, and the arc-shaped flipping plate 43 is rotated at a certain angle through the meshing of the teeth 47, thereby flipping the pipes on the arc-shaped placement plate 46 into the discharge channel 61 and sliding downward. During the downward sliding process of the pipes, the inclined plate 63 and the elastic element 62 buffer them to avoid the impact force of the descent being too large and damaging the pipes. Then, the pipes fall one by one into the push-pull plate 64 for storage, separating the pipes for easy protection.

[0043] The working principle of this invention is as follows: First, two pipes are placed on the Y-shaped plate 51 and the arc-shaped placement plate 46 by manual labor or a robotic arm; then, the two L-shaped plates 21 are driven to move towards the middle, and the welding torch 210 is inserted into the pipe. When the frustum-shaped disk 214 contacts the pipe, it will push the pipe to move synchronously, thereby connecting the two pipes. At this time, the cylinder 53 is activated, and the flipping plate 54 drives the pressing plate 55 to press it from the outside. The cylinder 26 is activated, and the moving block 27 and the movable rod 28 push the support plate 29 to contact the inner wall of the pipe, which is convenient for supporting pipes of different diameters from the inner and outer walls.

[0044] Then, the two splicing seats 31 are spliced ​​together, and the two arc-shaped toothed rings 34 are also spliced ​​together. Then, the cylinder 39 is activated, which drives the limit plate 37 to retract, so that the arc-shaped toothed ring 34 can rotate. The welding torch 36 is adjusted to contact the pipe surface. The gear 1 is activated, which drives the arc-shaped toothed ring 34 to rotate, and the welding torch 36 welds its surface. At the same time, the cylinder 211 is activated, which drives the welding torch 210 to move to the designated position. Then, the rotary motor 22 is activated, which drives the transmission shaft 25 to rotate through the pulley 1 23 and pulley 24. The transmission shaft 25 drives the cylinder 211 and the welding torch 210 to rotate to weld the inner wall of the pipe.

[0045] After welding is completed, clamping mechanism 5 and internal welding mechanism 2 are released, and internal welding mechanism 2 and external welding mechanism 3 are driven to move to both sides. Then, lifting seat 45 drives the pipe to move upward and drives flipping seat 41 to move horizontally a certain distance to avoid contact with external welding mechanism 3 during the flipping process. Then, gear 42 is started to rotate, and the arc-shaped flipping plate 43 is rotated at a certain angle through the meshing of teeth 47. Then, the pipe on arc-shaped placement plate 46 is flipped into the discharge channel 61 and slides downward. During the downward sliding of the pipe, the inclined plate 63 and elastic element 62 buffer it to avoid the impact force of the descent being too large and damaging the pipe. Then, the pipes fall one by one into the push-pull plate 64 for storage, separating the pipes to avoid contact and damage between the pipes, and at the same time making it easy to take out the pipes one by one.

[0046] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
