Description

Technical Field

[0001] The present application relates to the technical field of steel column welding, and in particular to a steel column welding device. Background Art

[0002] In the field of steel structure engineering, steel column welding is a key process for achieving high-strength and rigid connections of components. Its core goal is to form a continuous and stable overall structure to transfer loads and meet stability requirements. With the development of prefabricated buildings, full-circumferential automated welding of steel columns has become the core direction for improving efficiency and quality.

[0003] In the relevant technology, the existing steel column welding equipment generally adopts the driving method of single gear and single gear ring meshing. However, when the fixed component (including the welding gun) rotates around the steel column, the unilateral meshing gear system will cause the fixed component to bear asymmetric driving force, which in turn causes problems such as motion trajectory deviation and operation jamming, which can easily lead to uneven weld thickness and unstable molten pool temperature field, and then cause welding defects such as porosity, weld nodules, and lack of fusion, affecting structural safety.

[0004] In addition, traditional equipment also has certain shortcomings in steel column fixation and equipment maintenance. The rigid clamping device lacks adaptive adjustment capabilities. For steel columns of different diameters, manual disassembly and reassembly of the clamping components are required, and the positioning accuracy is significantly affected by human factors. Summary of the Invention

[0005] The present application aims to solve one of the technical problems in the related art at least to a certain extent.

[0006] To this end, one purpose of this application is to provide a steel column welding equipment that can effectively solve the problems of easy overloading and inconvenient fixing of steel columns in traditional single-gear drive, and achieve uniform and stable welding of steel columns around the entire circumference, thereby effectively improving construction efficiency, weld quality and equipment adaptability.

[0007] To achieve the above-mentioned purpose, the present application proposes a steel column welding equipment, comprising a workbench, a welding gun, a fixing device and a rotating device, wherein the fixing device comprises a clamping assembly and an auxiliary assembly, wherein the clamping assembly and the auxiliary assembly are respectively arranged on the workbench, and the clamping assembly cooperates with the auxiliary assembly to clamp and fix the two steel columns to be welded; the rotating device comprises a supporting assembly, a fixing assembly and a driving assembly, wherein the supporting assembly is fixedly installed on the workbench, and the supporting assembly is sleeved on the outer periphery of the two steel columns to be welded; the fixing assembly is movably arranged on the rail body of the supporting assembly, and the welding gun is arranged on the fixing assembly; the driving assembly is arranged in the supporting assembly, and the driving assembly is connected to the fixing assembly, and the driving assembly is used to drive the fixing assembly to rotate around the welding point of the two steel columns to be welded.

[0008] The steel column welding equipment of this application can effectively solve the problems of easy overloading and inconvenient fixing of steel columns in traditional single-gear drive, and achieve uniform and stable welding of steel columns in all directions, thereby effectively improving construction efficiency, weld quality and equipment adaptability.

[0009] In addition, the steel column welding equipment proposed in the present application may also have the following additional technical features: Specifically, the top of the workbench is provided with a slide groove for placing the auxiliary components, and there are four slide grooves, which are distributed in a rectangular array on the top of the workbench.

[0010] Specifically, a support frame for supporting two steel columns to be welded is fixedly installed on the top of the workbench, and there are four support frames, which are distributed on the top of the workbench in a linear array.

[0011] Specifically, the auxiliary component includes a sliding rod fixedly installed in two adjacent left and right sliding grooves, and the two sliding rods are symmetrically distributed in the sliding grooves in the front and back directions. The rod body of the sliding rod is equipped with a spring for cooperating with the clamping component to clamp and fix the two steel columns to be welded.

[0012] Specifically, the clamping assembly includes a fixed sleeve plate mounted on the sliding rod for left and right movement, a connecting column fixedly installed on the top end of the fixed sleeve plate for moving left and right following the spring, and a clamping plate fixedly installed on the top end of the connecting column for clamping and fixing two steel columns to be welded.

[0013] Specifically, the support assembly includes two support columns fixedly installed on the top of the workbench, a connecting plate fixedly installed on the right end of the support column, a guide rail fixedly installed on the right end of the connecting plate for circular motion of the fixed assembly, and a groove is provided at the right end of the guide rail.

[0014] Specifically, a first gear ring is movably connected in the guide rail for assisting the driving component to control the fixed component to perform circular motion around the guide rail, and the first gear ring can rotate around the groove in the guide rail. A second gear ring is provided below the first gear ring for cooperating with the first gear ring to assist the driving component to control the fixed component to perform circular motion around the guide rail.

[0015] Specifically, the driving assembly includes a rotating shaft that passes through the guide rail for rotation, and the shaft body of the rotating shaft is connected to the rail body of the guide rail through a bearing. A motor for driving the rotating shaft to rotate is fixedly installed at the left end of the rotating shaft, and the shaft end of the output shaft of the motor is connected to the left end of the rotating shaft through a coupling.

[0016] Specifically, the fixed assembly includes a sliding frame mounted on the guide rail, and the sliding frame can perform circular motion around the guide rail. A transmission shaft for rotation is provided in the frame of the sliding frame, and the transmission shaft can be connected to the frame body of the sliding frame through a bearing. The left end of the transmission shaft is provided with a second gear for meshing with the first gear ring and the second gear ring. A connecting rod is fixedly installed on the right end of the sliding frame, and a first fixing ring is fixedly installed on the right end of the connecting rod. A second fixing ring for cooperating with the first fixing ring to install the welding gun is provided on the right side of the first fixing ring.

[0017] Compared with the prior art, the present invention has the following advantages: 1. The clamping and fixation is convenient and efficient, and it is adaptable to steel columns of different sizes: the spring on the sliding rod is stretched by the fixing sleeve, and the elastic force of the spring reset is used to push the clamping plate to clamp the steel column. No complicated manual adjustment is required, and the fixation of steel columns of different diameters can be completed quickly with strong adaptability. In addition, the four concave support frames distributed in a linear array can stably support the steel column and limit its horizontal position, and cooperate with the clamping assembly to form a multi-dimensional fixation to prevent the steel column from shaking during welding.

[0018] 2. The double-tooth ring drive structure balances the force to ensure welding accuracy: the drive assembly simultaneously engages the first and second tooth rings through the first gear, so that the fixed components (sliding frame and welding gun) are subjected to bidirectional balanced driving force on the guide rail, avoiding the motion trajectory deviation or jamming caused by unilateral force in traditional single-gear drive. The synchronous rotation of the double tooth rings ensures that the welding gun revolves around the welding point of the steel column at a constant speed, effectively controlling the uniformity of weld thickness and the stability of the molten pool, improving welding quality, and reducing defects such as weld nodules and lack of fusion.

[0019] 3. Automated circumferential welding improves construction efficiency: The rotating device drives the welding gun to complete 360° circular motion, eliminating the need for manual adjustment of the welding gun position. Circumferential welding of steel columns can be completed in one go, reducing manual intervention and equipment start-up and shutdown times, shortening the construction cycle. The welding gun is fixed by bolts connected to the first and second fixing rings, making assembly and disassembly easy. The modular structure of the drive assembly (motor, shaft, gear) and the support assembly (guide rail, gear ring) facilitates later maintenance and component replacement.

[0020] 4. Compact and stable structure, suitable for a wide range of scenarios: The slide, support frame and rotating device are distributed in a rectangular array, with a compact structure and balanced force. It is suitable for various scenarios such as factory prefabrication and on-site installation, especially for steel structure projects with high welding precision requirements. The meshing transmission of the double gear ring and the double gear enhances the stability of the mechanical structure, reduces equipment wear caused by unbalanced loads, extends service life, and ensures long-term operation reliability.

[0031] In one embodiment of the present application, Figure 2 and Figure 3 As shown, a slide groove 101 for placing the auxiliary component 310 is provided on the top of the workbench 100 , and there are four slide grooves 101 , which are distributed in a rectangular array on the top of the workbench 100 .

[0032] A support frame 102 for supporting two steel columns to be welded is fixedly installed on the top of the workbench 100, and there are four support frames 102. The four support frames 102 are distributed in a linear array on the top of the workbench 100, and the four support frames 102 are located in the middle of the four slide grooves 101. At the same time, the cross-section of the support frame 102 is concave.

[0033] Specifically, four support frames 102 can be conveniently used to support the two steel columns to be welded, so that the rotating device 400 can be conveniently used to control the welding gun 200 to perform circumferential welding around the gap between the two steel columns to be welded.

[0034] In one embodiment of the present application, Figure 3As shown, the auxiliary component 310 may include a sliding rod 311 fixedly installed in two adjacent left and right slide grooves 101, and the two sliding rods 311 are symmetrically distributed in the slide groove 101 in the front and back direction.

[0035] Furthermore, the clamping assembly 320 may include a fixed sleeve 321 mounted on the slide rod 311 for left and right movement, wherein the shape and size of the fixed sleeve 321 are the same as the shape and size of the slide groove 101, thereby ensuring that the fixed sleeve 321 moves along the slide groove 101, and the top end of the fixed sleeve 321 is fixedly installed with a connecting column 322 for moving left and right following the spring 312, and the top end of the connecting column 322 is fixedly installed with a clamping plate 323 for clamping and fixing two steel columns to be welded.

[0036] Specifically, when it is necessary to weld two steel columns to be welded, the fixed sleeve 321 can be controlled to move along the slide rod 311 away from the rotating device 400, and the spring 312 on the slide rod 311 can be stretched, and then the two steel columns are placed on the support frame 102. Then, under the elastic action of the spring 312 in the stretched state, the clamping plate 323 on the fixed sleeve 321 can be controlled to clamp and fix the two steel columns, so as to facilitate the use of the rotating device 400 to control the welding gun 200 to weld around the gap between the two steel columns.

[0037] In one embodiment of the present application, Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the support assembly 410 may include two support columns 411 fixedly installed on the top of the workbench 100, and a connecting plate 412 is fixedly installed on the right end of the support column 411. A guide rail 413 for circular motion of the fixed assembly 430 is fixedly installed on the right end of the connecting plate 412, and a groove is provided at the right end of the guide rail 413.

[0038] Furthermore, a first gear ring 414 is movably connected in the guide rail 413 for assisting the driving component 420 to control the fixed component 430 to perform circular motion around the guide rail 413, and the first gear ring 414 can rotate around the groove in the guide rail 413. A second gear ring 415 is provided below the first gear ring 414 for cooperating with the first gear ring 414 to assist the driving component 420 to control the fixed component 430 to perform circular motion around the guide rail 413.

[0039] Furthermore, the drive assembly 420 may include a rotating shaft 422 that passes through the guide rail 413 for rotation, and the shaft body of the rotating shaft 422 is connected to the rail body of the guide rail 413 through a bearing to facilitate the rotation of the rotating shaft 422. The left end of the rotating shaft 422 is fixedly installed with a motor 421 for driving the rotating shaft 422 to rotate, and the shaft end of the output shaft of the motor 421 is connected to the left end of the rotating shaft 422 through a coupling to facilitate the control of the rotation of the rotating shaft 422 by the motor 421. The right end of the rotating shaft 422 is fixedly installed with a first gear 423 for meshing with the first gear ring 414 and the second gear ring 415.

[0040] Specifically, the rotation of the rotating shaft 422 can be controlled by the motor 421, and under the meshing connection between the first gear 423 and the first gear ring 414 and the second gear ring 415, the first gear ring 414 and the second gear ring 415 can be rotated synchronously, so that the fixing assembly 430 can move in a circular motion around the guide rail 413 to control the welding gun 200 to weld the two steel columns.

[0041] In one embodiment of the present application, Figure 5 and Figure 6 As shown, the fixing assembly 430 may include a sliding frame 431 mounted on the guide rail 413, and the sliding frame 431 may perform a circular motion around the guide rail 413. A transmission shaft 436 for rotation is provided in the frame of the sliding frame 431, and the transmission shaft 436 may be connected to the frame body of the sliding frame 431 through a bearing to facilitate the rotation of the transmission shaft 436. The left end of the transmission shaft 436 is provided with a second gear 435 for meshing with the first gear ring 414 and the second gear ring 415. A connecting rod 432 is fixedly installed on the right end, and a first fixing ring 433 is fixedly installed on the right end of the connecting rod 432. A second fixing ring 434 is provided on the right side of the first fixing ring 433 for cooperating with the first fixing ring 433 to install the welding gun 200. The first fixing ring 433 and the second fixing ring 434 can be fixedly connected by a threaded connection between a bolt and a nut to fix the welding gun 200.

[0042] Specifically, the motor 421 drives the rotating shaft 422 to rotate, and under the meshing connection between the first gear 423 and the first gear ring 414 and the second gear ring 415, the first gear ring 414 and the second gear ring 415 can rotate synchronously in the guide rail 413. At the same time, the rotating first gear ring 414 and the second gear ring 415 are meshed and connected with the second gear 435, so that the sliding frame 431 can perform a circular motion around the guide rail 413, so that the welding gun 200 on the first fixed ring 433 and the second fixed ring 434 can be controlled to weld the two steel columns.

[0043] Specifically, the overall workflow and principles of this application are as follows: 1. Initial preparation and clamping space creation: An auxiliary component 310 is installed in the four slide grooves 101 at the top of the workbench 100, including a slide rod 311 and a spring 312; the fixed sleeve 321 of the clamping component 320 is initially located outside the slide groove 101, and the spring 312 is in a naturally extended state. The operator pushes the fixed sleeve 321 away from the rotating device 400, stretching the spring 312 to a preset position, so that the clamping plate 323 is away from the center of the workbench, making room for the placement of the steel column.

[0044] Then place the two steel columns to be welded horizontally on the four concave support frames 102 in the middle of the workbench 100, with the axis of the steel column fitting into the concave groove of the support frame. The geometric shape of the support frame is used to limit the vertical displacement and horizontal offset of the steel column to ensure that the welding joints are aligned. After releasing the external force, the spring 312 is reset due to the elastic potential energy, pushing the fixed sleeve 321 to move along the slide rod 311 toward the steel column, and driving the clamping plate 323 to gradually fit the outer periphery of the steel column through the connecting column 322.

[0045] The elastic deformation of the spring 312 is automatically adjusted with the diameter of the steel column to ensure that steel columns of different sizes can be stably clamped. The clamping plate provides clamping force in the horizontal direction and the support frame provides support in the vertical direction, forming a four-way fixation (front, back, up and down).

[0046] 2. Welding gun installation and trajectory calibration: Place the welding gun 200 between the first fixing ring 433 and the second fixing ring 434, align the bolt holes of the two, tighten them with bolts and nuts, align the welding gun nozzle with the center of the steel column joint, ensure the welding starting point is accurate, confirm that the motor 421 is firmly connected to the rotating shaft 422, and the first gear 423 simultaneously engages the first gear ring 414 and the second gear ring 415 in the guide rail 413, and the gear meshing gap is uniform.

[0047] Manually rotate the rotating shaft 422 to observe whether the sliding frame 431 rotates smoothly along the guide rail 413 and whether the movement trajectory of the welding gun 200 forms a complete circle and coincides with the joint of the steel column. If the trajectory is offset, calibrate the welding gun position by adjusting the installation angle of the first / second fixing ring or the thickness of the gasket.

[0048] 3. Full circumferential welding execution: After the motor 421 is powered on, it drives the rotating shaft 422 to rotate through the coupling, and the first gear 423 at the right end of the rotating shaft drives the first gear ring 414 and the second gear ring 415 to rotate synchronously in the guide rail 413.

[0049] The double gear ring engages with the transmission shaft 436 of the fixed assembly 430 through the second gear 435, so that the sliding frame 431 is subjected to symmetrical driving force, avoiding the unilateral load of the traditional single gear drive, and ensuring that the welding gun moves in a circular motion along the guide rail at a constant linear speed.

[0050] The welding gun 200 arrives at the preset starting point (such as the top of the steel column) with the sliding frame 431, automatically ignites the arc, and starts welding. The sliding frame 431 completes a 360° rotation around the guide rail 413, and the welding gun synchronously completes the circumferential seam welding of the steel column. During this period, the double-toothed ring drive ensures that the welding gun movement trajectory is stable, the weld thickness is uniform, the molten pool maintains dynamic balance, and defects such as porosity and lack of fusion are reduced.

[0051] As a possible scenario, sensors (not shown in the figure) can be installed in the equipment to monitor the welding current, voltage and welding gun position in real time. If an abnormality occurs, the system will automatically alarm and pause the motor, and continue the operation after manual inspection.

[0052] 4. Welding completion and equipment reset: After welding is completed, the motor 421 stops running and the sliding frame 431 returns to its initial position. The operator manually stretches the spring 312 again to loosen the clamping plate 323 from the steel column, removes the welded steel column from the support frame 102, and cleans the welding slag and metal splashes in the workbench 100 and the guide rail 413, and lubricates the gears, bearings and other moving parts to ensure smooth operation next time. The fixed sleeve 321 is reset to the outside of the slide groove 101, and the spring 312 returns to its natural extension state, preparing for the welding of the next group of steel columns.

[0053] In summary, the steel column welding equipment of the embodiment of the present application can effectively solve the problems of easy overloading of traditional single-gear drive and inconvenient fixing of steel columns, and achieve uniform and stable welding of steel columns around the entire circumference, thereby effectively improving construction efficiency, weld quality and equipment adaptability.
