[0018] An automatic welding process for steel components comprises the following steps:

[0019] S1. First, according to the width of the horizontal plate and the vertical plate, move the fixing device to a suitable position in the moving groove, and fix the position of the fixing device with bolts, then insert the horizontal plate between the upper clamping plate and the lower clamping plate. As the horizontal plate is inserted, the pressure plate is pushed to rotate, so that the pressure plate squeezes the airbag, pushes the gas in the airbag into the telescopic tube, and extends the inner rod on the limit plate in the telescopic tube, pushing the installation plate to move in the avoidance groove, and then rotate the straightening plate to make the straightening plate vertical, and use bolt 2 and nut 2 to fix the straightening plate, and then insert the vertical plate between the two sets of straightening plates;

[0020] S2. Then, push the horizontal plate and the vertical plate to move their end faces to the adjustment ring, insert the welding torch into the installation slot, align the welding torch with the joint of the horizontal plate and the vertical plate, and fix the position of the welding torch through three bolts, and then start the welding torch to weld and fix the front ends of the horizontal plate and the vertical plate;

[0021] S3. Finally, the linear drive is started to move the fixed cylinder on the fixed table. During the movement, the block in the cavity on the fixed cylinder rotates until one end of the block abuts against the stopper and the other end abuts against the cross plate to fix the cross plate, thereby pushing the cross plate forward. While the cross plate moves, the block in the cavity on the fixed cylinder on the supporting table rotates, pressing the spring downward to cause the cross plate to slide in the fixed cylinder. At this time, the welding torch welds the moving cross plate and vertical plate. When the linear drive moves the fixed table to the extreme position, it drives the fixed table to move in the opposite direction. At this time, the block in the cavity on the fixed cylinder on the fixed table rotates, pressing the spring downward to reset the fixed cylinder on the fixed table. At the same time, the block in the cavity on the fixed cylinder on the supporting table rotates until one end of the block abuts against the stopper and the other end abuts against the cross plate to fix the cross plate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The locking member in the present invention can ensure that the horizontal plate is firmly fixed at a predetermined position during the welding process. The contact between the clamping block and the stopper in the cavity can effectively prevent any accidental movement or displacement of the horizontal plate during the welding process, thereby ensuring the accuracy and stability of welding. The locking member automatically follows the movement of the horizontal plate for adjustment, so that the horizontal plate can be automatically fixed after reaching the specified position, and cooperates with the linear drive to perform continuous forward movement, thereby performing long seam welding, reducing manual intervention and improving operation efficiency.

[0024] 2. In the present invention, the position of the vertical plate can be accurately adjusted and fixed by the cooperation of the telescopic tube and the airbag, so that it forms a stable T-shape with the horizontal plate. The gas compression and expansion function of the airbag enables the vertical plate to be finely adjusted as needed, thereby improving the flexibility and adaptability of the entire welding process;

[0025] 3. In the present invention, the welding torch can be accurately inserted and aligned with the joint of the steel structure through the adjustment ring and the installation groove. This precise positioning can ensure the accuracy of the weld position and angle during the welding process, thereby improving the welding quality. The threaded groove 2 and bolt 3 of the adjustment ring allow fine adjustment of the height and angle of the welding torch. This flexible adjustment function enables the welding device to adapt to steel structures of different specifications and shapes and meet various welding needs. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0041] Reference Figures 1 to 5In an embodiment of the present invention, an automatic welding device for steel components and an automatic welding process include: a base 1, a support platform 2 is fixedly connected to the base 1, a fixing tube 3 is fixedly connected to the supporting platform 2, a fixing device 4 is provided on the fixing tube 3, a horizontal plate 6 is slidably provided on the fixing device 4, and the horizontal plate 6 is clamped, a supporting device 5 is provided on the fixing device 4, a vertical plate 7 is slidably provided on the supporting device 5, and the vertical plate 7 is straightened so that the horizontal plate 6 and the vertical plate 7 form a T shape, and two groups of fixing devices 4 and supporting devices 5 are provided in each group of fixing tubes 3;

[0042] The fixing device 4 includes an adjusting block 41 connected to the fixing tube 3, a lower clamping plate 42 and an upper clamping plate 43 are fixedly arranged on the adjusting block 41, and the lower clamping plate 42 and the upper clamping plate 43 are symmetrically distributed at the upper and lower ends of the adjusting block 41, balls are rotatably arranged on the lower clamping plate 42 and the upper clamping plate 43, and the diameter of the balls is greater than the thickness of the lower clamping plate 42 and the upper clamping plate 43, a cavity 423 is opened at the top end of the lower clamping plate 42, and a cavity 423 is also opened at the bottom end of the upper clamping plate 43, and a locking member 44 is arranged in the cavity 423;

[0043] The supporting device 5 includes a telescopic tube 51 fixedly connected to the adjusting block 41. One end of the telescopic tube 51 passes through the adjusting block 41 and is connected with an airbag 52. The other end of the telescopic tube 51 is fixedly connected with a mounting plate 53. A pressing plate 54 is hinged on one side of the adjusting block 41 to protect the airbag 52 and prevent the airbag 52 from being scratched by the transverse plate 6. When the transverse plate 6 is inserted between the lower clamping plate 42 and the upper clamping plate 43, the pressing plate 54 is pushed to rotate to squeeze the airbag 52, so that the gas in the airbag 52 enters the telescopic tube 51 in the contracted state, and pushes the telescopic tube 51 to extend, driving the mounting plate 53 to move on the fixed tube 3. The multiple groups of inner tubes inside the telescopic tube 51 are sealed by sealing gaskets to prevent gas leakage.

[0044] The locking member 44 includes a block 441 rotatably connected to the cross plate 6, and the block 441 is rotatably connected to the cavity 423. A stopper 442 is fixedly provided at the bottom end of the cavity 423. When the cross plate 6 moves to one end, the block 441 is driven to rotate until the block 441 abuts against the stopper 442, so that the block 441 no longer rotates, and the cross plate 6 is abutted and fixed, so that the cross plate 6 no longer moves.

[0045] Reference Figure 1 A linear drive 8 is arranged on the base 1, and a movable end of the linear drive 8 is fixedly connected to a fixed table 9. A welding device 10 is arranged on the base 1, and the welding device 10 is located on one side of the support table 2. A fixed cylinder 3 is also fixedly connected to the fixed table 9. The support table 2 and the fixed table 9 are arranged in two groups, and four groups of linear drives 8 are arranged, which are symmetrically distributed on both sides of the welding device 10.

[0046] For this purpose, in the present technical solution, the linear drive 8 adopts the existing technology, which is composed of a motor, a screw, a guide rail, a transmission part and a control system. The screw is driven to rotate by the motor, and the screw is connected to the slider on the guide rail. When the screw rotates, the slider produces a linear motion along the guide rail.

[0047] The above scheme is adopted: by arranging two groups of support platforms 2 and fixed platforms 9 on both sides of the welding device 10, it is helpful to distribute the weight of the steel structure more evenly and reduce the deformation or instability caused by uneven gravity. The symmetrically distributed linear drive 8 and fixed platform 9 can ensure the uniform transmission of force during the welding process, making the welding process more stable and reducing the welding error caused by asymmetric force.

[0048] Reference Figure 3 and Fig.11 The side end of the fixed cylinder 3 is provided with a thread groove 31, and the thread groove 31 is provided with two groups, which are symmetrically provided on both sides of the fixed cylinder 3. The inner wall of the fixed cylinder 3 is provided with a moving groove 32, and the inner wall of the fixed cylinder 3 is provided with an avoidance groove 33, which is located on one side of the moving groove 32. The moving groove 32 is provided with two groups, which are symmetrically provided on both sides of the avoidance groove 33. The telescopic tube 51 is arranged in the avoidance groove 33, and a bolt 411 is provided through one end of the adjusting block 41. The bolt 411 is provided with two groups, which are symmetrically distributed on the adjusting block 41. On both sides of the segment block 41, a bolt 411 is threadedly connected to the thread groove 31, and the other end of the adjustment block 41 is fixedly connected to a sliding member 412. The sliding member 412 is provided with two groups. The sliding member 412 is slidably connected to the movable groove 32. The upper end of the lower clamping plate 42 is fixedly connected to a stud 421. The stud 421 penetrates the adjustment block 41 and the upper clamping plate 43. A nut 422 is provided at the top of the upper clamping plate 43. The nut 422 is threadedly connected to the stud 421. The nut 422 and the stud 421 are provided with four groups.

[0049] The above scheme is adopted: the fixed cylinder 3 is used to provide stable support for the steel structure during the welding process, which can effectively prevent the steel structure from moving or tilting during the welding process, ensuring the welding quality and structural accuracy. The fixed cylinder 3 is used in conjunction with the fixing device 4 and the supporting device 5 to accurately position the horizontal plate 6 and the vertical plate 7 of the steel structure. Through the adjustment of the adjustment block 41 and the bolt 411 and other components, the fixed cylinder 3 can ensure that the clamping position between the horizontal plate 6 and the vertical plate 7 is accurate, which helps to ensure the docking quality of the welding seam.

[0050] Reference Figure 4 The side end of the block 441 is fixedly connected to a connecting plate 443, the lower end of the connecting plate 443 is fixedly connected to a spring 444, one end of the spring 444 is fixedly connected to the bottom end of the cavity 423, and there are multiple groups of blocks 441, which are evenly distributed inside the cavity 423.

[0051] The above solution is adopted: the spring 444 allows the block 441 to automatically adjust its position to adapt to different welding requirements. As the welding proceeds, the elastic characteristics of the spring 444 allow the block 441 to adjust itself within a certain range to ensure the continuous and stable fixation of the cross plate 6.

[0052] Reference Figure 6 A straightening plate 55 is provided at the lower end of the mounting plate 53, and a second bolt 56 is penetrated and connected to the side end of the straightening plate 55, and the second bolt 56 penetrates the mounting plate 53. A second nut 57 is provided on one side of the mounting plate 53, and the second bolt 56 is threadedly connected to the second nut 57. A roller is rotatably connected inside the straightening plate 55, and the diameter of the roller is greater than the thickness of the straightening plate 55.

[0053] With the above solution, the design of the straightening plate 55 can effectively fix the vertical plate 7 in the correct position, ensuring that it is perpendicular to the horizontal plate 6. This vertical positioning is essential for maintaining the accurate geometry of the component during the welding process, thereby avoiding welding errors and structural asymmetry. With the support of the straightening plate 55, the vertical plate 7 can remain stable during the welding process, which helps to ensure the uniformity and continuity of the welded joint. A stable joint helps to improve welding quality and reduce defects and unevenness.

[0054] Reference Figures 7 to 10 The inner wall of the telescopic tube 51 is fixedly connected to a limiting plate 511, and the limiting plate 511 is O-shaped. The telescopic tube 51 can be limited by the limiting plate 511 to prevent the outer tube of the telescopic tube 51 from being blocked when the telescopic tube 51 contracts, so that the gas cannot enter the inner tube of the telescopic tube 51 and the telescopic tube 51 cannot be extended.

[0055] By adopting the above solution, the limiting plate 511 inside the telescopic tube 51 can prevent the telescopic tube 51 from over-contracting, thereby ensuring the stability of operation, avoiding the problem that gas cannot enter the inner tube, and ensuring that the telescopic tube 51 maintains normal extension and contraction functions during operation.

[0056] Reference Fig.12 The welding device 10 includes a support frame 101 fixedly connected to the base 1. The support frame 101 is provided with two groups, which are symmetrically distributed on both sides of the base 1. An adjusting ring 102 is fixedly connected to one side of the support frame 101. A mounting groove 103 is provided on the inner wall of the adjusting ring 102. A welding torch 104 is inserted into the mounting groove 103. A second thread groove 105 is provided on the side end of the adjusting ring 102. The second thread groove 105 is through-connected with the mounting groove 103. A third bolt 106 is threadedly connected to the second thread groove 105. One end of the third bolt 106 passes through the second thread groove 105 and abuts against the welding torch 104.

[0057] For this purpose, in the present technical solution, the welding torch 104 adopts the existing technology and is a tool for metal welding and cutting. It is a device used in welding and cutting processes such as arc welding and gas cutting, and is used to transport and mix protective gas, welding wire or gas flame to achieve the purpose of welding or cutting metal.

[0058] The above scheme is adopted: through the adjustment ring 102 and the installation groove 103, the welding torch 104 can be accurately inserted and aligned with the joint of the steel component. This precise positioning can ensure the accuracy of the weld position and angle during the welding process, thereby improving the welding quality. The thread groove 2 105 and the bolt 3 106 of the adjustment ring 102 allow fine adjustment of the height and angle of the welding torch 104. This flexible adjustment function enables the welding device 10 to adapt to steel components of different specifications and shapes and meet various welding needs.

[0059] The working principle of the present invention is as follows: first, according to the width of the horizontal plate 6 and the vertical plate 7, the fixing device 4 is moved to a suitable position in the moving groove 32, and the position of the fixing device 4 is fixed by using a bolt 411, and then the horizontal plate 6 is inserted between the upper clamping plate 43 and the lower clamping plate 42. As the horizontal plate 6 is inserted, the pressing plate 54 is pushed to rotate, so that the pressing plate 54 squeezes the airbag 52, and the gas in the airbag 52 is pushed into the telescopic tube 51, so that the inner rod on the limit plate 511 in the telescopic tube 51 extends, and the mounting plate 53 is pushed to move in the avoidance groove 33, and then the horizontal plate 6 is inserted between the upper clamping plate 43 and the lower clamping plate 42. The straightening plate 55 is moved to a vertical position, and the straightening plate 55 is fixed with a second bolt 56 and a second nut 57. Then, the vertical plate 7 is inserted between the two sets of straightening plates 55. Then, the horizontal plate 6 and the vertical plate 7 are pushed to move their end faces to the adjusting ring 102. The welding torch 104 is inserted into the mounting groove 103, and the welding torch 104 is aligned with the joint of the horizontal plate 6 and the vertical plate 7. The position of the welding torch 104 is fixed with a third bolt 106. Then, the welding torch 104 is started to weld and fix the front ends of the horizontal plate 6 and the vertical plate 7. Finally, the linear drive 8 is started to make the welding torch 104 move to the horizontal plate 6 and the vertical plate 7. The fixed cylinder 3 on the fixed platform 9 moves, and during the movement, the block 441 in the cavity 423 on the fixed cylinder 3 rotates until one end of the block 441 abuts against the stopper 442, and the other end abuts against the cross plate 6, fixing the cross plate 6, thereby pushing the cross plate 6 to move forward. While the cross plate 6 moves, the block 441 in the cavity 423 on the fixed cylinder 3 on the supporting platform 2 rotates, pressing the spring 444 downward, causing the cross plate 6 to slide out of the fixed cylinder 3. At this time, the welding torch 104 welds the moving cross plate 6 and the vertical plate 7. When the linear drive 8 makes the fixed cylinder 3 move, the clamping block 441 in the cavity 423 on the fixed cylinder 3 on the supporting platform 2 rotates, pressing the spring 444 downward, causing the cross plate 6 to slide out of the fixed cylinder 3. When the fixed platform 9 moves to the extreme position, it drives the fixed platform 9 to move in the opposite direction. At this time, the block 441 in the cavity 423 on the fixed cylinder 3 on the fixed platform 9 rotates, pressing the spring 444 downward to reset the fixed cylinder 3 on the fixed platform 9. At the same time, the block 441 in the cavity 423 on the fixed cylinder 3 on the supporting platform 2 rotates until one end of the block 441 abuts against the stopper 442 and the other end abuts against the horizontal plate 6 to fix the horizontal plate 6. Then, the linear drive 8 repeats the movement and reset of the fixed platform 9 to continuously weld the long seams of the horizontal plate 6 and the vertical plate 7.The locking member 44 can ensure that the horizontal plate 6 is firmly fixed in the predetermined position during the welding process. The contact between the block 441 and the stopper 442 in the cavity 423 can effectively prevent any accidental movement or displacement of the horizontal plate 6 during the welding process, thereby ensuring the accuracy and stability of welding. The locking member 44 automatically follows the movement of the horizontal plate 6 for adjustment, so that the horizontal plate 6 can be automatically fixed after reaching the specified position, and cooperates with the linear drive 8 to perform continuous forward movement, thereby performing long seam welding, reducing manual intervention and improving the efficiency of the operation. The position of the vertical plate 7 can be accurately adjusted and fixed through the cooperation of the telescopic tube 51 and the airbag 52, so that it is aligned with the horizontal plate 6 forms a stable T-shape. The gas compression and expansion function of the airbag 52 enables the vertical plate 7 to be finely adjusted as needed, thereby improving the flexibility and adaptability of the entire welding process. Through the adjustment ring 102 and the installation groove 103, the welding torch 104 can be accurately inserted and aligned with the joint of the steel member. This precise positioning can ensure the accuracy of the weld position and angle during the welding process, thereby improving the welding quality.
