Description

Technical Field

[0001] This invention relates to the field of welding platform technology, specifically to an integrated steel structure assembly and welding platform. Background Technology

[0002] The integrated steel structure assembly and welding platform is a comprehensive work platform that integrates steel structure assembly and welding functions. It integrates the assembly and positioning of steel structure components and the welding process in the same working environment. With the help of high-precision positioning devices and flexible adjustment mechanisms, it can quickly and accurately realize the spatial positioning and assembly of steel structure components, achieve process integration and positioning precision, and significantly improve production efficiency, welding quality and safety.

[0003] When welding lightweight steel structures, multiple steel components are often assembled into a steel structure first. The positioning fixture is then inserted into the positioning hole of the welding platform, and finally the steel structure is clamped by the fixture before welding. However, it is difficult to weld the bottom of the steel structure. The fixture needs to be removed first, the steel structure needs to be flipped over, and the fixture needs to be used to fix the steel structure before welding the bottom of the steel structure. This operation is relatively complicated and reduces welding efficiency. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an integrated steel structure assembly and welding platform, including a welding table, a positioning plate, two support seats, a motor and several positioning holes. The inner wall of the welding table is slidably connected to the outer wall of the positioning plate, and the inner walls of the two support seats are rotatably connected to the outer walls of the two welding tables. Several positioning holes are opened on the inner wall of the positioning plate. The side wall of the left support is fixedly connected to the side wall of the motor, and the side wall of the motor output end is fixedly connected to the side wall of the support. It also includes: a lifting mechanism, a clamping mechanism and a blocking mechanism. The top of the lifting mechanism is fixedly connected to the bottom of the welding table; The outer wall of the clamping mechanism is slidably connected to the inner wall of the welding table; The side wall of the blocking mechanism is fixedly connected to the side wall of the support base; The lifting mechanism includes: a drive assembly, a pressing assembly, and two guide frames; The top of the drive assembly is fixedly connected to the bottom of the welding station; The outer wall of the extrusion assembly is slidably connected to the inner wall of the welding station; The tops of both guide frames are slidably connected to the inner wall of the positioning plate; The clamping mechanism includes: a reversing assembly, a limiting assembly, and four pressing plates; The outer wall of the commutation component is slidably connected to the inner wall of the welding station; The outer wall of the limiting component is slidably connected to the inner wall of the welding station; The outer walls of the four extrusion plates are slidably connected to the inner wall of the welding station; The blocking mechanism includes: a hydraulic assembly and a blocking assembly; The side wall of the hydraulic component is fixedly connected to the side wall of the support base; The outer wall of the sealing component is fixedly connected to the inner wall of the hydraulic component; In use, the operator places multiple steel components on top of the positioning plate, selects a suitable position for assembly, and then inserts multiple positioning clamps into the positioning holes of the positioning plate. After that, the positioning clamps hold the steel components to make them stable. After clamping, the operator welds the steel components with an external welding gun to connect the multiple steel components into a steel structure.

[0005] Preferably, the drive assembly also includes two electrically operated telescopic rods; The tops of both electric telescopic rods are fixedly connected to the bottom of the welding table, the top output ends of both electric telescopic rods are fixedly connected to the bottom of both guide frames, and the outer walls of both guide frames are slidably connected to the inner walls of the welding table. When welding is required at the bottom of the steel structure, the electric telescopic rod is retracted, causing the guide frame to descend, which in turn lowers the positioning plate, thus lowering the steel structure.

[0006] Preferably, the extrusion assembly also includes four sliding frames and four positioning rods; The outer walls of the four sliding frames are slidably connected to the inner wall of the welding table. The four positioning rods are in pairs, and the side walls of the two sets of positioning rods are fixedly connected to the left and right sides of the welding table, respectively. As the guide frame continues to move, it comes into contact with the sliding frame, thereby pushing the sliding frame to descend.

[0007] Preferably, the reversing assembly also includes four push frames and four rotating frames; The outer walls of the four push frames are slidably connected to the inner walls of the welding table, and the inner walls of the four rotating frames are rotatably connected to the outer walls of the four positioning rods. The side walls of the four push frames are slidably connected to the inner walls of the four rotating frames, and the inner walls of the four rotating frames are slidably connected to the tops of the four sliding frames. When the sliding frame descends, it pulls the rotating frame to rotate, changing the tilt angle of the rotating frame. This causes one side of the rotating frame to descend while the other side moves towards the guide frame. The side moving towards the guide frame pulls the pushing frame to move. Since the rotating frame rotates around the positioning rod, and the positioning rod is close to the sliding frame, the lever arm on the side of the rotating frame closer to the sliding frame is shorter, while the lever arm on the side closer to the pushing frame is longer. This creates lever arms of different lengths. According to the lever principle, the distance moved is proportional to the lever arm, so the pushing frame will move a greater distance.

[0008] Preferably, the limiting assembly also includes four spring rods; The outer walls of the four spring rods are slidably connected to the inner walls of the four push frames, and the side walls of the four spring rods are fixedly connected to the side walls of the four extrusion plates. When the pusher moves, it pushes the spring rod and the extrusion plate to move. At this time, the extrusion plate will come into contact with the descending positioning plate, so the extrusion plate will be blocked. The spring rod will accumulate elastic potential energy until the positioning plate descends and separates from the extrusion plate. At this time, the rebound force of the spring rod will be released, pushing the extrusion plate to move towards the steel structure. Until the extrusion plate contacts the steel structure, the extrusion plate will be blocked again, and the push frame will continue to move, which will squeeze the spring rod, allowing the spring rod to accumulate elastic potential energy and enhance the clamping force of the extrusion plate on the steel structure. Since the steel structure is welded into a whole, it will keep the steel structure stable, making it difficult for the steel structure to follow the positioning plate down. As the positioning plate continues to descend, the positioning fixture will be blocked by the steel structure, which will cause the positioning fixture to separate from the positioning hole of the positioning plate until the positioning plate separates from the welding table. After that, the operator will take out multiple positioning fixtures. After the removal is completed; The starting motor drives the welding table to rotate clockwise. As the welding table rotates, the center of gravity of the positioning plate changes due to its own weight. The positioning plate then slides down, causing the protrusion on top of the positioning plate to contact the welding table and block it until the welding table is fully rotated. The unwelded bottom of the steel structure is then exposed. Afterward, the operator welds the bottom of the steel structure, achieving double-sided welding of the steel structure in one clamping. This solves the problem of having to remove the clamps and rotate the steel structure for bottom welding, thereby improving welding efficiency.

[0009] Preferably, the hydraulic assembly also includes four hydraulic cylinders and four spring piston rods; The four hydraulic cylinders are arranged in pairs, and the side walls of the two sets of hydraulic cylinders are fixedly connected to the side of the two support seats near the welding table. The interior of each of the four hydraulic cylinders is filled with hydraulic oil. The inner walls of the four hydraulic cylinders are slidably connected to the outer walls of the four spring piston rods. The tops of the four spring piston rods are fixedly connected to the side of the four sliding frames near the motor. Each of the four hydraulic cylinders has a sealing ring fixedly connected to its inner wall, and the inner walls of the four sealing rings are slidably connected to the outer walls of the four spring piston rods to prevent hydraulic oil leakage.

[0010] Preferably, the sealing assembly also includes four oil supply pipes and four spring ball joints; The outer walls of the four oil pipes are all connected to the inner walls of the four hydraulic cylinders, and the inner walls of the four spring ball joints are all slidably connected to the outer walls of the four oil pipes. The four spring ball joints are paired up. The bottom of both sets of spring ball joints near the welding table is in contact with the top of the two guide frames. The four spring ball joints are in a compressed state. The inner walls of the four oil pipes are fixedly connected with sealing rings II. The inner walls of the four sealing rings II are slidably connected to the outer walls of the four spring ball joints to prevent hydraulic oil leakage. After welding is completed at the bottom of the steel structure, the motor is started again to drive the welding table to rotate clockwise, which in turn drives the positioning plate to rotate. As the rotation angle increases, the positioning plate will slide down again due to its own weight until the protrusion on the top of the positioning plate contacts the welding table, blocking the positioning plate until the welding table rotates back to its original position. Then, the electric telescopic rod is started to extend, pushing the guide frame and positioning plate to rise, so that the positioning plate returns to its original position, and the operator can then move the welded steel structure. Secondly, when the guide frame descends, it will separate from the spring ball joint, and the spring ball joint's rebound force will be released. It will descend and contact the guide frame again until the spring ball joint contacts the inclined surface of the inner wall of the oil pipe. The spring ball joint will then stop moving. When the sliding frame descends, it will drive the spring piston rod to descend, allowing it to accumulate rebound force, which will cause the spring piston rod to squeeze the hydraulic oil in the hydraulic cylinder. The squeezed hydraulic oil enters the oil supply pipe, pushing the spring ball head rod to separate from the inclined surface of the oil supply pipe, allowing it to accumulate rebound force. The hydraulic oil then moves through the oil supply pipe to the top of the spring piston rod until the sliding frame stops moving. The rebound force of the spring ball head rod is released, causing it to fall and once again adhere to the inclined surface of the oil supply pipe, blocking the flow of hydraulic oil. After the welding table flips back to its original position, when the electric telescopic rod extends and pushes the guide frame to rise, the guide frame will separate from the sliding frame. At this time, because the hydraulic oil in the hydraulic cylinder will be blocked by the spring ball joint rod, the rebound force of the spring piston rod is difficult to release, which will keep the sliding frame in a downward state, allowing the extrusion plate to continuously extrude the steel structure. As the guide frame continues to rise, the guide frame will contact the spring ball joint rod. At this time, the positioning plate will also approach the extrusion plate, and the guide frame will push the spring ball joint rod to rise, putting it in a compressed state. By separating the spring ball joint rod from the inclined surface of the oil pipe, allowing the hydraulic oil to flow smoothly, the rebound force of the spring piston rod is released, causing the sliding frame to return to its original position. This pushes the rotating frame to rotate again, pulling the push frame, spring rod, and extrusion plate back to their original positions. This releases the fixation on the steel structure, allowing the steel structure to fall onto the top of the positioning plate. This effectively prevents the sliding frame, push frame, and extrusion plate from rapidly returning to their original positions when the guide frame rises, which would cause the steel structure to separate quickly from the positioning plate. This would result in a longer distance between the steel structure and the positioning plate, causing the steel structure to fall from a height and impact the positioning plate, potentially damaging the steel structure. This ensures the integrity of the steel structure.

[0011] The present invention has the following beneficial effects: (1) When using this invention, the operator stabilizes the steel component by using multiple positioning clamps. The operator then welds the steel component with an external welding gun to make it a whole. The positioning plate and steel structure are lowered by the drive assembly. The steel structure is then clamped by the squeezing assembly, reversing assembly and limiting assembly to keep it stable until the positioning plate separates from the welding table. The motor is started to drive the welding table to rotate clockwise, which will cause the center of gravity of the positioning plate to change and slide down until the welding table is flipped. The unwelded bottom of the steel structure will then be exposed. After that, the operator welds the bottom of the steel structure, realizing double-sided welding of the steel structure in one clamping. This solves the problem of having to remove the clamps and flip the steel structure for welding the bottom, thereby improving the welding efficiency.

[0012] (2) When the sliding frame descends, the spring piston rod will descend. After the welding table flips back to its original position, when the electric telescopic rod extends to push the guide frame to rise, the guide frame will separate from the sliding frame. The sealing component will keep the sliding frame in a descending state, allowing the extrusion plate to continuously extrude the steel structure until the positioning plate is close to the steel structure. The guide frame pushes the sealing component to rise to cancel the fixation of the steel structure, allowing the steel structure to fall to the top of the positioning plate. This effectively prevents the sliding frame, the push frame, and the extrusion plate from quickly returning to their original positions when the guide frame rises, which would cause the steel structure to quickly separate from the steel structure. This would result in a longer distance between the steel structure and the positioning plate, causing the steel structure to fall from a height and impact the positioning plate, which could easily cause damage to the steel structure. This ensures the integrity of the steel structure.

[0013] (3) When the positioning plate is separated from the welding table, the operator can directly take the positioning fixture and quickly remove the fixture, shortening the time for removing the fixture and realizing rapid disassembly of the fixture. At the same time, after the steel structure welding is completed, the steel structure can be directly transported after the welding table is flipped back to its original position, further reducing the time for disassembling the fixture. This effectively prevents the use of a large number of positioning fixtures when welding steel structures with multiple intersecting components, which would require a long time to remove the positioning fixtures, thereby speeding up the disassembly speed of the fixtures and improving the turnover rate of the welding table.

[0014] (4) By setting the bottom of the welding table as an inclined surface and the top of the positioning plate as an inclined surface, when the positioning plate is not fully aligned with the inner wall of the welding table after the positioning plate is flipped back to its original position for the second time, the inclined surface of the positioning plate will contact the inclined surface of the welding table when the positioning plate rises, so that the positioning plate is squeezed, thereby adjusting the position of the positioning plate and moving the positioning plate to the inner wall of the welding table, ensuring that the sliding frame can return to its original position accurately.

[0018] 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.

[0019] Example 1, please refer to Figures 1-8 The present invention is a steel structure assembly and welding integrated platform, including a welding table 13, a positioning plate 14, two support seats 15, a motor 16 and several positioning holes. The inner wall of the welding table 13 is slidably connected to the outer wall of the positioning plate 14, and the inner walls of the two support seats 15 are rotatably connected to the outer walls of the two welding tables 13. Several positioning holes are opened on the inner wall of the positioning plate 14. The side wall of the left support 15 is fixedly connected to the side wall of the motor 16, and the side wall of the output end of the motor 16 is fixedly connected to the side wall of the support 15. It also includes: lifting mechanism 1, clamping mechanism 2 and blocking mechanism 3. The top of the lifting mechanism 1 is fixedly connected to the bottom of the welding table 13; The outer wall of the clamping mechanism 2 is slidably connected to the inner wall of the welding table 13; The side wall of the blocking mechanism 3 is fixedly connected to the side wall of the support base 15; The lifting mechanism 1 includes: a drive assembly 11, a pressing assembly 12, and two guide frames 112; The top of the drive assembly 11 is fixedly connected to the bottom of the welding station 13; The outer wall of the extrusion assembly 12 is slidably connected to the inner wall of the welding station 13; The tops of both guide frames 112 are slidably connected to the inner wall of the positioning plate 14; The clamping mechanism 2 includes: a reversing assembly 21, a limiting assembly 22, and four pressing plates 221; The outer wall of the commutation assembly 21 is slidably connected to the inner wall of the welding station 13; The outer wall of the limiting component 22 is slidably connected to the inner wall of the welding table 13; The outer walls of the four extrusion plates 221 are slidably connected to the inner wall of the welding table 13; The blocking mechanism 3 includes: a hydraulic assembly 31 and a blocking assembly 32; The side wall of the hydraulic assembly 31 is fixedly connected to the side wall of the support base 15; The outer wall of the sealing component 32 is fixedly connected to the inner wall of the hydraulic component 31; In use, the operator places multiple steel components on top of the positioning plate 14, selects a suitable position for assembly, and after assembly, as follows: Figure 3 As shown in the position of G, the operator then inserts multiple positioning clamps into the positioning holes of the positioning plate 14. Afterwards, the positioning clamps stabilize the steel component. Figure 3 As shown in the middle H position, after clamping is completed, the operator welds the steel components using an external welding gun, connecting multiple steel components into a steel structure.

[0020] Example 2, please refer to Figures 3-16 The present invention is a steel structure assembly and welding integrated platform. Based on Example 1, the drive component 11 also includes two electric telescopic rods 111. The tops of the two electric telescopic rods 111 are fixedly connected to the bottom of the welding table 13, the top output ends of the two electric telescopic rods 111 are fixedly connected to the bottoms of the two guide frames 112, and the outer walls of the two guide frames 112 are slidably connected to the inner walls of the welding table 13. When welding is required at the bottom of the steel structure, the electric telescopic rod 111 is activated to retract, causing the guide frame 112 to descend, which in turn causes the positioning plate 14 to descend, thus lowering the steel structure.

[0021] The extrusion assembly 12 also includes four sliding frames 121 and four positioning rods 122; The outer walls of the four sliding brackets 121 are slidably connected to the inner wall of the welding table 13. The four positioning rods 122 are in pairs, and the side walls of the two sets of positioning rods 122 are fixedly connected to the left and right sides of the welding table 13, respectively. As the guide frame 112 continues to move, it will come into contact with the sliding frame 121, thereby pushing the sliding frame 121 to descend.

[0022] The reversing assembly 21 also includes four pushers 211 and four rotating frames 212; The outer walls of the four push frames 211 are slidably connected to the inner walls of the welding table 13, and the inner walls of the four rotating frames 212 are rotatably connected to the outer walls of the four positioning rods 122. The side walls of the four push frames 211 are slidably connected to the inner walls of the four rotating frames 212, and the inner walls of the four rotating frames 212 are slidably connected to the tops of the four sliding frames 121. When the sliding frame 121 descends, it pulls the rotating frame 212 to rotate, changing the tilt angle of the rotating frame 212. This causes one side of the rotating frame 212 to descend while the other side moves towards the guide frame 112. The side moving towards the guide frame 112 pulls the push frame 211 to move. Since the rotating frame 212 rotates around the positioning rod 122 and the positioning rod 122 is close to the sliding frame 121, the lever arm of the rotating frame 212 closer to the sliding frame 121 is shorter, while the lever arm of the side closer to the push frame 211 is longer, resulting in lever arms of different lengths. According to the lever principle, the moving distance is proportional to the lever arm, so the push frame 211 will move a greater distance.

[0023] The limiting assembly 22 also includes four spring rods 222; The outer walls of the four spring rods 222 are slidably connected to the inner walls of the four push frames 211, and the side walls of the four spring rods 222 are fixedly connected to the side walls of the four extrusion plates 221. When the pusher 211 moves, it will push the spring rod 222 and the pressing plate 221 to move. At this time, the pressing plate 221 will come into contact with the descending positioning plate 14, so the pressing plate 221 will be blocked. The spring rod 222 will accumulate elastic potential energy until the positioning plate 14 descends and separates from the pressing plate 221. At this time, the rebound force of the spring rod 222 will be released, pushing the pressing plate 221 to move towards the steel structure. Until the extrusion plate 221 contacts the steel structure, it will be blocked again. The pusher 211 continues to move, squeezing the spring rod 222, allowing it to accumulate elastic potential energy and increasing the clamping force of the extrusion plate 221 on the steel structure. Since the steel structure is welded into a single unit, it remains stable, making it difficult for the steel structure to descend with the positioning plate 14. As the positioning plate 14 continues to descend, the positioning fixture will be blocked by the steel structure, causing it to separate from the positioning hole of the positioning plate 14, until the positioning plate 14 separates from the welding table 13. Figure 13 As shown, the operator then removes multiple positioning fixtures, and the removal is complete; The starter motor 16 drives the welding table 13 to rotate clockwise. During this rotation, as the tilt angle of the welding table 13 increases, the center of gravity of the positioning plate 14 shifts. Due to its own weight, it will slide down. Figure 14 As shown, the protrusion on the top of the positioning plate 14 contacts the welding table 13, as shown. Figure 14 As shown in the position of J, the positioning plate 14 is blocked until the welding table 13 completes its rotation, as shown. Figure 15As shown, the unwelded bottom of the steel structure will be exposed. Then, the operator will weld the bottom of the steel structure, realizing double-sided welding of the steel structure in one clamping. This solves the problem of having to remove the clamp and flip the steel structure when welding the bottom, thereby improving welding efficiency.

[0024] Hydraulic assembly 31 also includes four hydraulic cylinders 311 and four spring piston rods 312; The four hydraulic cylinders 311 are arranged in pairs, and the side walls of the two sets of hydraulic cylinders 311 are fixedly connected to the side of the two support seats 15 near the welding table 13. The interior of the four hydraulic cylinders 311 is filled with hydraulic oil. The inner walls of the four hydraulic cylinders 311 are slidably connected to the outer walls of the four spring piston rods 312. The tops of the four spring piston rods 312 are fixedly connected to the side of the four sliding frames 121 near the motor 16. A sealing ring is fixedly connected to the inner wall of each of the four hydraulic cylinders 311. The inner walls of the four sealing rings are slidably connected to the outer walls of the four spring piston rods 312 to prevent hydraulic oil leakage.

[0025] The sealing assembly 32 also includes four oil delivery pipes 321 and four spring ball joints 322; The outer walls of the four oil pipes 321 are all connected to the inner walls of the four hydraulic cylinders 311, and the inner walls of the four spring ball joints 322 are all slidably connected to the outer walls of the four oil pipes 321. The four spring ball joints 322 are in pairs. The bottom of the two sets of spring ball joint rods 322 near the welding table 13 is in contact with the top of the two guide frames 112. The four spring ball joint rods 322 are in a compressed state. The inner wall of the four oil pipes 321 is fixedly connected with sealing rings 2. The inner wall of the four sealing rings 2 is slidably connected to the outer wall of the four spring ball joint rods 322 to prevent hydraulic oil leakage. After welding is completed at the bottom of the steel structure, the motor 16 is started again to drive the welding table 13 to rotate clockwise, which in turn drives the positioning plate 14 to rotate. As the rotation angle increases, the positioning plate 14 will slide down again due to its own weight until the protrusion on the top of the positioning plate 14 contacts the welding table 13, blocking the positioning plate 14. The welding table 13 is rotated back to its original position. Then, the electric telescopic rod 111 is started to extend, pushing the guide frame 112 and the positioning plate 14 to rise, so that the positioning plate 14 returns to its original position. The operator can then move the welded steel structure. Secondly, as the guide frame 112 descends, it separates from the spring ball joint 322. The rebound force of the spring ball joint 322 is released, and it descends again to contact the guide frame 112 until the spring ball joint 322 contacts the inclined surface of the inner wall of the oil pipe 321. Figure 11As shown in position I, the spring ball joint rod 322 will stop moving. When the sliding frame 121 descends, it will drive the spring piston rod 312 to descend, allowing it to accumulate rebound force, so that the spring piston rod 312 squeezes the hydraulic oil in the hydraulic cylinder 311. The squeezed hydraulic oil enters the oil supply pipe 321, pushing the spring ball head rod 322 to separate from the inclined surface of the oil supply pipe 321, allowing it to accumulate rebound force. The hydraulic oil then moves through the oil supply pipe 321 to the top of the spring piston rod 312 until the sliding frame 121 stops moving. The rebound force of the spring ball head rod 322 is released, causing it to descend and once again adhere to the inclined surface of the oil supply pipe 321, blocking the flow of hydraulic oil. After the welding table 13 flips back to its original position, when the electric telescopic rod 111 extends and pushes the guide frame 112 to rise, the guide frame 112 will separate from the sliding frame 121. At this time, because the hydraulic oil in the hydraulic cylinder 311 will be blocked by the spring ball head rod 322, the rebound force of the spring piston rod 312 is difficult to release, which will keep the sliding frame 121 in a downward state, allowing the extrusion plate 221 to continuously extrude the steel structure. As the guide frame 112 continues to rise, the guide frame 112 will contact the spring ball head rod 322. At this time, the positioning plate 14 will also approach the extrusion plate 221, and the guide frame 112 will push the spring ball head rod 322 to rise, putting it in a compressed state. By separating the spring ball joint rod 322 from the inclined surface of the oil pipe 321, the hydraulic oil can flow smoothly. The rebound force of the spring piston rod 312 will be released, causing the sliding frame 121 to return to its original position. This will push the rotating frame 212 to rotate again, pulling the push frame 211, spring rod 222, and extrusion plate 221 back to their original positions. This will release the fixation on the steel structure, allowing the steel structure to fall onto the top of the positioning plate 14. This effectively prevents the sliding frame 121, push frame 211, and extrusion plate 221 from quickly returning to their original positions when the guide frame 112 rises. This would prevent the sliding frame 121, push frame 211, and extrusion plate 221 from quickly separating from the steel structure, which would result in a longer distance between the steel structure and the positioning plate 14. This would cause the steel structure to fall from a height and impact the positioning plate 14, potentially causing damage to the steel structure. This ensures the integrity of the steel structure.

[0026] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0027] One specific application of this embodiment is as follows: When using this invention, the operator places multiple steel components on top of the positioning plate 14, selects a suitable position for assembly, and after assembly, as follows: Figure 3 As shown in the position of G, the operator then inserts multiple positioning clamps into the positioning holes of the positioning plate 14. Afterwards, the positioning clamps stabilize the steel component. Figure 3 As shown in the position of H, after clamping is completed, the operator welds the steel components with an external welding gun to connect multiple steel components into a steel structure. When welding is required at the bottom of the steel structure, the electric telescopic rod 111 is activated to retract, causing the guide frame 112 to descend, which in turn causes the positioning plate 14 to descend, thus lowering the steel structure. As the guide frame 112 continues to move, it will come into contact with the sliding frame 121, thereby pushing the sliding frame 121 to descend. This causes the sliding frame 121 to pull the rotating frame 212 to rotate, changing the tilt angle of the rotating frame 212. This causes one side of the rotating frame 212 to descend, while the other side moves toward the guide frame 112. The side that moves toward the guide frame 112 will pull the push frame 211 to move. Since the rotating frame 212 rotates around the positioning rod 122, and the positioning rod 122 is close to the sliding frame 121, the lever arm of the rotating frame 212 closer to the sliding frame 121 is shorter, and the lever arm of the rotating frame 212 closer to the pushing frame 211 is longer, which will form lever arms of different lengths. According to the lever principle, the moving distance is proportional to the lever arm. Therefore, the pushing frame 211 will move a greater distance. When the pushing frame 211 moves, it will push the spring rod 222 and the pressing plate 221 to move. At this time, the pressing plate 221 will come into contact with the descending positioning plate 14. Therefore, the pressing plate 221 will be blocked, and the spring rod 222 will accumulate elastic potential energy until the positioning plate 14 descends and separates from the pressing plate 221. At this time, the rebound force of the spring rod 222 will be released, pushing the pressing plate 221 to move towards the steel structure. Until the extrusion plate 221 contacts the steel structure, it will be blocked again. The pusher 211 continues to move, squeezing the spring rod 222, allowing it to accumulate elastic potential energy and increasing the clamping force of the extrusion plate 221 on the steel structure. Since the steel structure is welded into a single unit, it remains stable, making it difficult for the steel structure to descend with the positioning plate 14. As the positioning plate 14 continues to descend, the positioning fixture will be blocked by the steel structure, causing it to separate from the positioning hole of the positioning plate 14, until the positioning plate 14 separates from the welding table 13. Figure 13 As shown, the operator then removes multiple positioning fixtures, and the removal is complete; The starter motor 16 drives the welding table 13 to rotate clockwise. During this rotation, as the tilt angle of the welding table 13 increases, the center of gravity of the positioning plate 14 shifts. Due to its own weight, it will slide down. Figure 14 As shown, the protrusion on the top of the positioning plate 14 contacts the welding table 13, as shown. Figure 14 As shown in the position of J, the positioning plate 14 is blocked until the welding table 13 completes its rotation, as shown. Figure 15 As shown, the unwelded bottom of the steel structure will be exposed. Then, the operator will weld the bottom of the steel structure, realizing double-sided welding of the steel structure in one clamping. This solves the problem of having to remove the clamp and flip the steel structure when welding the bottom, thereby improving welding efficiency. After welding is completed at the bottom of the steel structure, the motor 16 is started again to drive the welding table 13 to rotate clockwise, which in turn drives the positioning plate 14 to rotate. As the rotation angle increases, the positioning plate 14 will slide down again due to its own weight until the protrusion on the top of the positioning plate 14 contacts the welding table 13, blocking the positioning plate 14. The welding table 13 is rotated back to its original position. Then, the electric telescopic rod 111 is started to extend, pushing the guide frame 112 and the positioning plate 14 to rise, so that the positioning plate 14 returns to its original position. The operator can then move the welded steel structure. Secondly, as the guide frame 112 descends, it separates from the spring ball joint 322. The rebound force of the spring ball joint 322 is released, and it descends again to contact the guide frame 112 until the spring ball joint 322 contacts the inclined surface of the inner wall of the oil pipe 321. Figure 11 As shown in position I, the spring ball joint rod 322 will stop moving. When the sliding frame 121 descends, it will drive the spring piston rod 312 to descend, allowing it to accumulate rebound force, so that the spring piston rod 312 squeezes the hydraulic oil in the hydraulic cylinder 311. The squeezed hydraulic oil enters the oil supply pipe 321, pushing the spring ball head rod 322 to separate from the inclined surface of the oil supply pipe 321, allowing it to accumulate rebound force. The hydraulic oil then moves through the oil supply pipe 321 to the top of the spring piston rod 312 until the sliding frame 121 stops moving. The rebound force of the spring ball head rod 322 is released, causing it to descend and once again adhere to the inclined surface of the oil supply pipe 321, blocking the flow of hydraulic oil. After the welding table 13 flips back to its original position, when the electric telescopic rod 111 extends and pushes the guide frame 112 to rise, the guide frame 112 will separate from the sliding frame 121. At this time, because the hydraulic oil in the hydraulic cylinder 311 will be blocked by the spring ball head rod 322, the rebound force of the spring piston rod 312 is difficult to release, which will keep the sliding frame 121 in a downward state, allowing the extrusion plate 221 to continuously extrude the steel structure. As the guide frame 112 continues to rise, the guide frame 112 will contact the spring ball head rod 322. At this time, the positioning plate 14 will also approach the extrusion plate 221, and the guide frame 112 will push the spring ball head rod 322 to rise, putting it in a compressed state. By separating the spring ball joint rod 322 from the inclined surface of the oil pipe 321, the hydraulic oil can flow smoothly. The rebound force of the spring piston rod 312 will be released, causing the sliding frame 121 to return to its original position. This will push the rotating frame 212 to rotate again, pulling the push frame 211, spring rod 222, and extrusion plate 221 back to their original positions. This will release the fixation on the steel structure, allowing the steel structure to fall onto the top of the positioning plate 14. This effectively prevents the sliding frame 121, push frame 211, and extrusion plate 221 from quickly returning to their original positions when the guide frame 112 rises. This would prevent the sliding frame 121, push frame 211, and extrusion plate 221 from quickly separating from the steel structure, which would result in a longer distance between the steel structure and the positioning plate 14. This would cause the steel structure to fall from a height and impact the positioning plate 14, easily causing damage to the steel structure. This ensures the integrity of the steel structure. Secondly, when the positioning plate 14 is separated from the welding table 13, the operator can directly pick up the positioning fixture and quickly remove it, shortening the time for removing the fixture and enabling rapid disassembly of the fixture. At the same time, after the steel structure welding is completed, the welding table 13 can be flipped back into place and the steel structure can be directly transported, further reducing the time for disassembling the fixture. This effectively prevents the use of a large number of positioning fixtures when welding steel structures with multiple intersecting components, which would require a long time to remove the positioning fixtures, thereby speeding up the disassembly speed of the fixtures and improving the turnover rate of the welding table 13. Secondly, by setting the bottom of the welding table 13 as an inclined surface and the top of the positioning plate 14 as an inclined surface, after the positioning plate 14 is flipped back into position for the second time, as... Figure 13 As shown, when the position of the positioning plate 14 is not fully aligned with the inner wall of the welding table 13, when the positioning plate 14 rises, the inclined surface of the positioning plate 14 will contact the inclined surface of the welding table 13, causing the positioning plate 14 to be squeezed, thereby adjusting the position of the positioning plate 14 and moving the positioning plate 14 to the inner wall of the welding table 13, ensuring that the sliding frame 121 can accurately return to its original position.
