[0001] This invention relates to the field of welding technology for building steel structures, specifically to a multi-plane positioning welding device and welding method for building steel structures. Background Technology

[0002] Steel structure welding refers to the technical process in the field of building engineering that uses heating, pressurization, or a combination of both to achieve atomic bonding between steel structure components, forming a strong connection. Its core purpose is to assemble disparate steel structure components into an overall structure that meets the building's load-bearing requirements and spatial form needs. It is a key process in the processing and installation of steel structures.

[0003] In the existing technology, the steel structure of a building is usually fixed first during the welding process. However, most existing devices only support welding on a single plane. If the side, top, or other different planes of the steel structure need to be welded, the workpiece needs to be disassembled and reassembled, resulting in low work efficiency.

[0015] A welding method for a multi-plane positioning welding device for building steel structures includes the following steps: S1. The workers place the external steel structure to be welded between the first rotating box and the second rotating box, start the first hydraulic rod to drive the fixed plate to move, and the fixed plate simultaneously drives the first toothed ring, the second toothed ring, the third toothed ring and the fourth toothed ring to move. At the same time, the motor is started to drive the track to rotate, and the track will drive the first toothed ring, the second toothed ring, the third toothed ring and the fourth toothed ring to rotate. S2. When the inner wall of the second toothed ring meshes with the outer surface of the second bidirectional toothed tooth, the second bidirectional toothed tooth will drive the toothed cylinder to slide. The toothed cylinder will drive the first rubber pad on the surface of the first clamping plate to fit tightly against the outer wall of the steel structure. At the same time, the second hydraulic rod will be activated, and the second hydraulic rod will drive the second clamping plate to move closer to the steel structure to be welded. S3. When the steel structure needs to be rotated during the welding process, the outer surface of the third toothed ring meshes with the outer surface of the first bidirectional toothed tooth, which will drive the first rotating shaft to rotate. The first rotating shaft will drive the first rotating box and the steel structure that has been clamped to rotate synchronously. S4. When the steel structure needs to be translated, the second helical gear rotates by meshing the first toothed ring with the second one-way toothed gear. The second helical gear drives the first lead screw to rotate, and the first lead screw pushes the fixed box to move along the inner wall of the first connecting frame, thereby driving the first rotating box and the clamped steel structure to move. When the steel structure needs to be translated in another direction, the rotational force of the first one-way toothed gear is converted into a linear movement force of the first connecting frame along the axis of the second lead screw by meshing the fourth toothed ring with the first one-way toothed gear, so that the first connecting frame can be smoothly translated in the preset direction.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In use, this device, through the setting of the first positioning component, and the synchronous cooperation of the rotation of the first rotating box and the second rotating box of the second positioning component, can drive the steel structure to flip, easily switching between different welding planes on the side and top surfaces; with the transmission cooperation of the moving component and the supporting component, the steel structure can be smoothly moved along two horizontal directions, accurately adjusting the welding position, improving the continuity of work, and solving the problem that existing devices only support welding on a single plane. If welding the side, top, and other different planes of the steel structure is required, manual disassembly and reassembly of the workpiece are required, resulting in low work efficiency. 2. In use, the first positioning component clamps one end of the steel structure from all sides through four first clamping plates with first rubber pads, and the second positioning component simultaneously fixes the other end through four second clamping plates with second rubber pads. The rubber pads not only prevent scratches on the workpiece surface, but also enhance friction to prevent slippage. The clamping power is achieved through precise transmission of gears, gear racks and hydraulic rods. The clamping force is uniform and controllable, which can adapt to steel structure components of different specifications and improve the applicability of the multi-plane positioning welding device for building steel structures. 3. During use, the integrated transmission of the motor, hydraulic rod, toothed ring, and gear set enables efficient linkage of clamping, adjustment, and welding. The track of the moving component cooperates with the toothed ring to quickly switch between different transmission paths, synchronously driving clamping, rotation, and translation, reducing operational complexity. At the same time, the transmission efficiency is high and the adjustment is precise, significantly improving the overall welding operation efficiency. Attached Figure Description

A fixed box 102 is rotatably connected to one outer surface of the first rotating box 101. Two bidirectional threaded rods 103 are movably embedded on opposite inner walls on both sides of the first rotating box 101. A first gear 104 is fixedly sleeved at the center of the outer surface of each of the two bidirectional threaded rods 103. A first gear 104 is fixedly embedded at the center of the other inner wall of the first rotating box 101. Shaft 105, a gear cylinder 106 is slidably connected to the outer surface of the first rotating shaft 105, a second rotating shaft 107 is movably embedded in one side of the fixed box 102 relative to the inner wall, a second gear 108 is fixedly sleeved on the outer surface of the second rotating shaft 107 near the center, a turbine 109 is fixedly sleeved on the outer surface of the second rotating shaft 107 near one end, a third rotating shaft 110 is movably embedded in the other side of the fixed box 102 relative to the inner wall, the outer surfaces of the two first gears 104 mesh with the outer surface of the gear cylinder 106, the outer surface of the second gear 108 meshes with the outer surface of the gear cylinder 106, a worm gear 111 is fixedly sleeved on the outer surface of the third rotating shaft 110 near one end, the outer surface of the worm gear 111 meshes with the outer surface of the turbine 109, the outer surface of the first rotating shaft 105... A first bidirectional toothed clamp 112 is fixedly sleeved near one end, and a second bidirectional toothed clamp 113 is fixedly sleeved on the outer surface of the third rotating shaft 110 near the other end. Two first sliders 114 are threadedly connected to the outer surfaces of the two bidirectional threaded rods 103. The outer surfaces of all four first sliders 114 are slidably connected to the inner wall of the first rotating box 101. A first clamping plate 115 is fixedly connected to one side of the outer surface of each of the four first sliders 114. A first rubber pad 116 is fixedly connected to one side of the outer surface of each of the four first clamping plates 115. A first lead screw 117 is threadedly connected to the inner wall of the fixed box 102. A first helical gear 118 is fixedly sleeved on the outer surface of the first lead screw 117 near one end. A first connecting frame 119 is slidably connected to the bottom of the fixed box 102. A second helical gear 120 is rotatably connected to one side inner wall of the first connecting frame 119. The outer surface of the first helical gear 118 meshes with the outer surface of the second helical gear 120. The support assembly 4 includes two support frames 401. A first slide rod 402 is rotatably connected to the outer surface of one support frame 401 near one side edge. A second slide rod 403 is fixedly connected to the outer surface of one support frame 401 near the center. A second lead screw 404 is rotatably connected to the outer surface of one support frame 401 near the other side edge. Three third slide rods 405 are rotatably connected to one side outer surface of the other support frame 401. One end of each of the three third slide rods 405 is fixedly connected to one end of the first slide rod 402, the second slide rod 403, and the second lead screw 404, respectively.

[0021] In this embodiment, when the steel structure needs to be rotated, the first hydraulic rod 201 drives the fixed plate 204 to move. The fixed plate 204 drives the rotating third toothed ring 208 to mesh with the outer surface of the first bidirectional toothed tooth 112, thereby driving the first rotating shaft 105 to rotate. When the first rotating shaft 105 rotates, it drives the first rotating box 101 to rotate. The outer surface of the first rotating box 101 rotates along the inner wall of the fixed box 102. At the same time, the first rotating box 101 drives one end of the steel structure that has been clamped inside to rotate synchronously. Since the other end of the steel structure is stably clamped by the second clamping plate 304 in the second rotating box 303, the second rotating box 303 is driven to rotate synchronously along the outer surface of the third slider 302. When it is necessary to rotate the steel structure, the first rotating shaft 105 rotates. When the steel structure is translated, the first hydraulic rod 201 drives the rotating first toothed ring 206 to mesh with the second one-way toothed gear 407, thereby causing the second one-way toothed gear 407 to rotate. The rotation of the second one-way toothed gear 407 drives the first slide rod 402 to rotate, which in turn drives the second helical gear 120 to rotate. The second helical gear 120 then drives the first helical gear 118 to rotate, which in turn drives the first lead screw 117 to rotate. The rotation of the first lead screw 117 pushes the fixed box 102 to move along the inner wall of the first connecting frame 119, thereby moving one end of the first rotating box 101 and the clamped steel structure component. Simultaneously, the other end of the steel structure component drives the second rotating box 303 to move. The box 303 will cause the outer surface of the third slider 302 to slide along the inner wall of the second moving frame 301. When the steel structure needs to be translated in another direction, the first hydraulic rod 201 will drive the rotating fourth toothed ring 209 to mesh with the first one-way toothed tooth 406, thereby driving the first one-way toothed tooth 406 to rotate. When the first one-way toothed tooth 406 rotates, it will drive the first connecting frame 119, which is rotatably connected to it, to slide along the second lead screw 404 of the support assembly 4. The inner wall of the first connecting frame 119 and the outer surface of the second lead screw 404 are threaded together, and the first connecting frame 119 is also slidably connected to the second slide rod 403. The second slide rod 403 plays a guiding and limiting role to prevent the first connecting frame 119 from rotating and deviating. The rotational force of the gear 406 is converted into a linear moving force of the first connecting frame 119 along the axial direction of the second lead screw 404, causing the first connecting frame 119 to smoothly translate in a preset direction. Since the first connecting frame 119 is fixedly connected to the second moving frame 301 of the second positioning assembly 3 through the second connecting frame 306, the translation of the first connecting frame 119 will synchronously drive the second moving frame 301 to slide along the three third sliding rods 405 of the support assembly 4. At the same time, the first connecting frame 119 also maintains a transmission connection with the fixed box 102 of the first positioning assembly 1. Therefore, the first positioning assembly 1 and the second positioning assembly 3 will move synchronously at the same speed and in the same direction, and the steel structural member clamped between them will also move along the translational direction. This device, by setting the first positioning assembly 1,By rotating the first rotating box 101 and synchronously cooperating with the second rotating box 303 of the second positioning component 3, the steel structure component can be rotated, easily switching between different welding planes on the side and top surfaces. With the transmission cooperation between the moving component 2 and the supporting component 4, the steel structure component can be smoothly moved along two horizontal directions, precisely adjusting the welding position and improving work continuity. This solves the problem that existing devices only support welding on a single plane; if welding the side, top, or other different planes of the steel structure is required, manual disassembly and reassembly of the workpiece are necessary, resulting in low work efficiency.

[0022] like Figure 1-10 As shown, a fourth toothed ring 209 is movably engaged on the inner wall of track 205 near the other side. The second positioning assembly 3 includes a second movable frame 301. A third slider 302 is slidably connected to the inner wall of the second movable frame 301. A second rotating box 303 is rotatably connected to one outer surface of the third slider 302. Four second clamping plates 304 are slidably connected to the inner wall of the second rotating box 303. A second rubber pad 305 is fixedly connected to one outer surface of each of the four second clamping plates 304. A second connecting frame 306 is fixedly connected between the first connecting frame 119 and the outer surface of the second movable frame 301. A first toothed row 307 is fixedly connected to the outer surface of two of the second clamping plates 304, and the other two second clamping plates 304 are fixedly connected to... A second gear rack 308 is connected to the second rotating box 303. A fourth rotating shaft 309 is movably embedded in the inner wall of the second rotating box 303. Two third gears 310 are fixedly sleeved on the outer surface of the fourth rotating shaft 309 near one end. The outer surfaces of the two first gear racks 307 mesh with the outer surface of one of the third gears 310. The outer surfaces of the two second gear racks 308 mesh with the outer surface of the other third gear 310. A fourth gear 311 is fixedly sleeved on the outer surface of the fourth rotating shaft 309 at the center. A second hydraulic rod 312 is fixedly connected to one side of the inner wall of the second rotating box 303 by screws. A third gear rack 313 is fixedly connected to one end of the second hydraulic rod 312. The outer surface of the third gear rack 313 meshes with the outer surface of the fourth gear 311.

[0023] In this embodiment, when a multi-plane positioning welding device for building steel structures is in use, the worker places the external steel structural component to be welded between the first rotating box 101 and the second rotating box 303. Then, the first hydraulic rod 201 is activated, which moves the second slider 202. The second slider 202 moves the slide rail 203, which in turn moves the fixing plate 204. Simultaneously, the fixing plate 204 moves the first toothed ring 206, the second toothed ring 207, the third toothed ring 208, and the fourth toothed ring 209. At the same time, the motor 211 is activated, which drives the roller 210 to rotate. When the roller 210 rotates, it drives the meshing track 205 to rotate. The track 205 drives the first toothed ring 206, the second toothed ring 207, the third toothed ring 208, and the fourth toothed ring 209 to rotate until the inner wall of the second toothed ring 207 meshes with the outer surface of the second bidirectional toothed tooth 113. At this point, the second bidirectional toothed tooth 113 rotates, which in turn drives the third shaft 110 to rotate. The third shaft 110 drives the worm gear 111 to rotate, which in turn drives the meshing turbine 109 to rotate. The turbine 109 drives the second shaft 107 to rotate, which in turn drives the second gear. When gear 108 rotates, the second gear 108 drives the inner wall of gear cylinder 106 to slide along the outer surface of the first rotating shaft 105. Simultaneously, gear cylinder 106 drives the two first gears 104 to rotate, and the two first gears 104 synchronously drive their corresponding bidirectional threaded rods 103 to rotate. Since the threads on the outer surface of the bidirectional threaded rods 103 are symmetrically distributed and are threadedly connected to the first sliders 114, the rotation of the two bidirectional threaded rods 103 drives the four first sliders 114 to slide towards each other along the inner wall of the first rotating box 101. As the first sliders 114 move, the first clamping plate 115, fixedly connected to one side of their outer surface, synchronously moves closer to the first clamping plate. When the steel structure to be welded is brought close, until the first rubber pad 116 on the surface of the first clamping plate 115 is in close contact with the outer wall of the steel structure, the second hydraulic rod 312 is activated. The second hydraulic rod 312 will drive the fourth gear 311 to rotate, the fourth gear 311 will drive the fourth rotating shaft 309 to rotate, and the fourth rotating shaft 309 will drive the two third gears 310 on the outer surface to rotate synchronously. When the third gear 310 meshing with the first gear row 307 rotates, it will drive the two first gear rows 307 to move towards each other along the inner wall of the second rotating box 303. The two first gear rows 307 will drive the corresponding two second clamping plates 304 to approach the steel structure to be welded synchronously.Simultaneously, the rotation of another third gear 310 meshing with the second gear rack 308 drives the two second gear racks 308 to move towards each other using the same transmission logic. This also causes the other two fixed second clamping plates 304 to move closer to the steel structure until both ends and multiple sides of the steel structure are clamped. The first positioning component 1 clamps one end of the steel structure from all sides using four first clamping plates 115 with first rubber pads 116. The second positioning component 3 simultaneously fixes the other end using four second clamping plates 304 with second rubber pads 305. The rubber pads prevent scratches on the workpiece surface and enhance friction to prevent slippage. The clamping power is achieved through precise transmission of gears, gear racks, and hydraulic rods. The clamping force is uniform and controllable, adaptable to steel structure components of different specifications, and improves the applicability of the multi-plane positioning welding device for building steel structures.

The inner wall of the second moving frame 301 is slidably connected to the outer surfaces of the three third slide rods 405.

[0025] In this embodiment, when a multi-plane positioning welding device for building steel structures is in use, if the steel structure needs to be rotated during the welding process, the first hydraulic rod 201 will drive the fixed plate 204 to move. The fixed plate 204 will simultaneously drive the rotating third toothed ring 208 to mesh with the outer surface of the first bidirectional toothed tooth 112, thereby driving the first rotating shaft 105 to rotate, and thus driving the steel structure to rotate synchronously. When the steel structure needs to be translated, the first hydraulic rod 201 will drive the rotating first toothed ring 206 to mesh with the second unidirectional toothed tooth 407, thereby driving the second unidirectional toothed tooth 407 to rotate. When the second unidirectional toothed tooth 407 rotates, it will drive the first sliding rod 402 to rotate, and the first sliding rod 402 will drive the steel structure to move. When the steel structure needs to be translated in another direction... During the shift, the first hydraulic rod 201 drives the rotating fourth toothed ring 209 to mesh with the first one-way toothed tooth 406, thereby causing the first one-way toothed tooth 406 to rotate. When the first one-way toothed tooth 406 rotates, it drives the second lead screw 404 to rotate. The rotational force of the first one-way toothed tooth 406 is converted into a linear moving force of the first connecting frame 119 along the axial direction of the second lead screw 404, so that the first connecting frame 119 can move smoothly in the preset direction. Through the integrated transmission of the motor 211, hydraulic rod, toothed ring, and gear set, efficient linkage of clamping, adjustment and welding is realized. The track 205 of the moving component 2 cooperates with the toothed ring to quickly switch different transmission paths and synchronously drive clamping, rotation and translation, reducing the complexity of operation. At the same time, the transmission efficiency is high and the adjustment is precise, which significantly improves the overall welding operation efficiency.

[0026] In this invention, a multi-plane positioning welding device for building steel structures is used such that when the worker places the external steel structural component to be welded between the first rotating box 101 and the second rotating box 303, the first hydraulic rod 201 is activated. The first hydraulic rod 201 drives the second slider 202 to move, the second slider 202 drives the slide rail 203 to move, the slide rail 203 drives the fixing plate 204 to move, and the fixing plate 204 simultaneously drives the first toothed ring 206, the second toothed ring 207, the third toothed ring 208, and the fourth toothed ring 209 to move. At the same time, the motor 211 is activated, which drives the roller 210 to rotate. The roller 210 drives the meshing track 205 to rotate, and the track 205 drives the first toothed ring 206 to rotate. 6. The second toothed ring 207, the third toothed ring 208, and the fourth toothed ring 209 rotate until the inner wall of the second toothed ring 207 meshes with the outer surface of the second bidirectional toothed gear 113. At this point, the second bidirectional toothed gear 113 will rotate, which in turn will drive the third rotating shaft 110 to rotate. The third rotating shaft 110 will drive the worm gear 111 to rotate, which in turn will drive the meshing turbine 109 to rotate. The turbine 109 will drive the second rotating shaft 107 to rotate, which in turn will drive the second gear 108 to rotate. The second gear 108 will cause the inner wall of the gear cylinder 106 to slide along the outer surface of the first rotating shaft 105. The gear cylinder 106 will simultaneously drive the two first gears 104 to rotate, and the two first gears 104 will rotate together. Each step drives the corresponding bidirectional threaded rod 103 to rotate. Since the threads on the outer surface of the bidirectional threaded rod 103 are symmetrically distributed and are threadedly connected to the first slider 114, the rotation of the two bidirectional threaded rods 103 will drive the four first sliders 114 to slide towards each other along the inner wall of the first rotating box 101. As the first slider 114 moves, the first clamping plate 115 fixedly connected to one side of its outer surface will synchronously approach the steel structure to be welded until the first rubber pad 116 on the surface of the first clamping plate 115 is tightly attached to the outer wall of the steel structure. At the same time, the second hydraulic rod 312 is activated, which drives the fourth gear 311 to rotate. The fourth gear 311 drives the fourth rotating shaft 309 to rotate, and the fourth rotating shaft 309 drives the outer surface... The two third gears 310 rotate synchronously. When the third gear 310 meshing with the first gear row 307 rotates, it drives the two first gear rows 307 to move towards each other along the inner wall of the second rotating box 303. The two first gear rows 307 drive the corresponding two second clamping plates 304 to move towards the steel structure to be welded synchronously. At the same time, the other third gear 310 meshing with the second gear row 308 rotates, driving the two second gear rows 308 to move towards each other with the same transmission logic. This also drives the other two second clamping plates 304 fixed to it to move towards the steel structure until the two ends and multiple sides of the steel structure are clamped. At this time, the external welding head can weld the external steel structure. When it is necessary to rotate the steel structure during the welding process,At this time, the first hydraulic rod 201 will drive the fixed plate 204 to move. The fixed plate 204 will synchronously drive the rotating third toothed ring 208 to mesh with the outer surface of the first bidirectional toothed tooth 112, thereby driving the first rotating shaft 105 to rotate. When the first rotating shaft 105 rotates, it will drive the first rotating box 101 to rotate. The outer surface of the first rotating box 101 will rotate along the inner wall of the fixed box 102. At the same time, the first rotating box 101 will drive one end of the steel structure component that has been clamped inside to rotate synchronously. Since the other end of the steel structure component is stably clamped by the second clamping plate 304 in the second rotating box 303, the second rotating box 303 will be synchronously driven to rotate along the outer surface of the third slider 302. When it is necessary to flatten the steel structure... During the shift, the first hydraulic rod 201 drives the rotating first toothed ring 206 to mesh with the second one-way toothed gear 407, thereby causing the second one-way toothed gear 407 to rotate. The rotation of the second one-way toothed gear 407 drives the first sliding rod 402 to rotate, which in turn drives the second helical gear 120 to rotate. The second helical gear 120 then drives the first helical gear 118 to rotate, which in turn drives the first lead screw 117 to rotate. The rotation of the first lead screw 117 pushes the fixed box 102 to move along the inner wall of the first connecting frame 119, thereby causing one end of the first rotating box 101 and the clamped steel structure to move. Simultaneously, the other end of the steel structure causes the second rotating box 303 to move. The box 303 will cause the outer surface of the third slider 302 to slide along the inner wall of the second moving frame 301. When the steel structure needs to be translated in another direction, the first hydraulic rod 201 will drive the rotating fourth toothed ring 209 to mesh with the first one-way toothed tooth 406, thereby driving the first one-way toothed tooth 406 to rotate. When the first one-way toothed tooth 406 rotates, it will drive the first connecting frame 119, which is rotatably connected to it, to slide along the second lead screw 404 of the support assembly 4. The inner wall of the first connecting frame 119 and the outer surface of the second lead screw 404 are threaded together, and the first connecting frame 119 is also slidably connected to the second slide rod 403. The second slide rod 403 plays a guiding and limiting role to prevent the first connecting frame 119 from rotating off-center. The rotational force of the first unidirectional tooth 406 is converted into a linear moving force of the first connecting frame 119 along the axial direction of the second lead screw 404, causing the first connecting frame 119 to smoothly translate in a preset direction. Since the first connecting frame 119 is fixedly connected to the second moving frame 301 of the second positioning assembly 3 through the second connecting frame 306, the translation of the first connecting frame 119 will synchronously drive the second moving frame 301 to slide along the three third sliding rods 405 of the support assembly 4. At the same time, the first connecting frame 119 also maintains a transmission connection with the fixed box 102 of the first positioning assembly 1. Therefore, the first positioning assembly 1 and the second positioning assembly 3 will move synchronously at the same speed and in the same direction, and the steel structural member clamped between them will also move along the translational direction.
