Description

Technical Field

[0001] This invention relates to the field of ring laser welding technology, specifically to an automatic processing system for ring-shaped steel plant columns. Background Technology

[0002] In actual production, steel plant columns are large in size and have many segments. On-site installation and welding are limited by space and environment, making it difficult to uniformly control quality. However, the automated circumferential welding process in the factory can transform the complex on-site splicing into standardized prefabrication, significantly improving production efficiency and ensuring the stability of weld quality. It is a necessary process to meet the needs of industrialized and standardized steel structure production, and to ensure the safety of engineering structures and construction progress. The circumferential welding process is the core link of the column segment splicing in the automated steel plant column processing system. This process connects column assembly with weld correction and non-destructive testing, and is a critical node in the factory prefabrication of steel columns. Its core purpose is to achieve full penetration butt welding of circumferential cross-section columns such as circular tube columns and box columns, ensuring equal strength connections between column segments.

[0003] During the circumferential welding process, when the two overlapping steel columns of the plant building rotate with the help of roller frames, uneven stress at the joint due to the weight and inertia of the steel columns can easily cause sinking and displacement. High welding temperatures soften and crack the positioning welds, rendering them ineffective. Asynchronous transmission on both sides of the roller frames leads to axial slippage of the column. Localized high welding temperatures cause thermal expansion and contraction, generating stress that pulls on the column, leading to misalignment. This manifests primarily as three states: axial movement, radial misalignment, and circumferential misalignment. Axial movement occurs when the two column sections... Slipping back and forth along the axial direction results in inconsistent gaps between the welds; radial misalignment occurs when the center of the column's joint surface shifts, causing one side of the weld to be too wide and the other too narrow, or even uneven laps; circumferential misalignment occurs when the two column sections rotate relative to each other in the circumferential direction, resulting in uneven bevel joints. Such misalignments directly cause defects in the circumferential weld quality, such as incomplete penetration, burn-through, and porosity. They also lead to excessive coaxiality and verticality of the steel column, affecting subsequent installation accuracy, exacerbating welding stress concentration, severely weakening the structural strength of the steel column, and creating potential safety hazards for the factory building. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides an automatic processing system for ring-shaped steel plant column bodies. This system effectively solves the problem in existing technologies where, during ring-shaped welding, the two overlapping sections of the steel plant column are prone to axial movement, radial misalignment, and circumferential displacement due to factors such as the steel column's own weight, heat failure of positioning welds, asynchronous roller transmission, and welding thermal deformation. These issues affect welding quality, installation accuracy, and the structural strength of the steel column.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides an automatic processing system for annular, wraparound steel plant column bodies, comprising:

[0007] A welded component, the welded component comprising a welding head for laser welding and a fixing frame supporting the welding head;

[0008] The base is located at the bottom end of the welding component fixing frame, and a sliding groove is provided at the top end of the base;

[0009] The clamp is embedded in the inner wall of the slide groove and is symmetrically arranged. Each clamp has a positioning element on an opposite side. The positioning element includes a positioning frame that engages with each other. A support frame is provided on the side of the positioning frame. A connecting rod is provided on the side of the support frame. The other end of the connecting rod is fixedly connected to the side of the base. A slider is fixedly connected to the bottom of the positioning frame and the support frame. The slider is slidably connected to the slide groove.

[0010] The support frame is provided with a positioning wheel in the middle that fits circumferentially with the column body.

[0011] Furthermore, both ends of the two positioning frames away from the support frame are symmetrically provided with a clamping plate and a groove, the outer wall of the clamping plate and the inner wall of the groove are equal in size, and an electromagnetic component is provided in the middle of the side of the positioning frame away from the support frame.

[0012] Furthermore, elastic elements are equidistantly arranged at the top of the positioning frame, and a retaining ring is provided at the top of the elastic element. Buffer pads are provided on both sides of the retaining ring.

[0013] Furthermore, a ring block is provided in the middle of the inner wall of the support frame, and a limiting groove is provided at equal intervals on the inner wall of the ring block, with the positioning wheel located on the inner wall of the limiting groove.

[0014] Furthermore, the ring block is provided with stop blocks at both ends, and the inner wall size of the stop blocks is smaller than the inner wall size of the ring block.

[0015] Furthermore, the outer wall of the positioning wheel is provided with a shallow toothed anti-slip layer, the middle of the positioning wheel is provided with a center wheel, the middle of the outer wall of the center wheel is provided with a positioning hole, the side of the positioning wheel is provided with a guide shaft, the center of the guide shaft is provided with a rotating shaft, and the bottom of the center wheel is provided with a positioning assembly.

[0016] Furthermore, the positioning assembly includes a locking pin with an arc-shaped design, the locking pin being symmetrically arranged at the top of the positioning ring, and a support rod being symmetrically fixedly connected to the bottom of the positioning ring.

[0017] Furthermore, a positioning rod is provided through the middle of the bottom end of the support rod, and the positioning rod is embedded in the inner wall of the movable groove, which is symmetrically arranged at the top of the fixed seat.

[0018] The technical solution provided by this invention has the following advantages compared with the prior art:

[0019] This invention incorporates a positioning component, which serves as the core positioning mechanism. It employs a triple positioning design of "radial clamping + axial limiting + circumferential anti-torsion," comprehensively restricting the displacement of the steel column and ensuring precise positioning throughout the rotational welding process. Radial clamping is achieved through the electromagnetic engagement structure of the positioning frame and the clamping action of the retaining ring. The two positioning frames engage with each other through the magnetic force of the electromagnetic component, with the retaining plate precisely matching the groove to form a ring-shaped enveloping structure, radially clamping the steel column joint. The elastic component at the top of the positioning frame drives the retaining ring to adaptively conform to the outer wall of the steel column, further enhancing the radial clamping effect, limiting radial displacement of the steel column, and solving the problem of radial misalignment.

[0020] The present invention is equipped with a stop block, which achieves axial limiting through the stop block of the support frame. The stop block is set at both ends of the ring block, and the inner wall size is smaller than the inner wall size of the ring block. It can accurately abut against the end step surface of the steel column, form a two-way axial constraint, limit the axial slippage of the steel column, and solve the problem of axial movement.

[0021] This invention achieves circumferential anti-torsion through the cooperation of positioning wheels and positioning groups. The positioning wheels are evenly distributed along the limiting groove of the ring block, and the shallow toothed anti-slip layer on the outer wall fits circumferentially with the steel column, increasing static friction and preventing the steel column from slipping circumferentially. The locking pin of the positioning group is inserted into the positioning hole of the center wheel to ensure accurate positioning of the positioning wheel, avoid positioning wheel offset, further enhance the circumferential anti-torsion effect, and solve the problem of circumferential misalignment.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] The present invention will be further described below with reference to embodiments.

[0033] Example:

[0034] Please see Figures 1-7 This invention provides a technical solution for an automatic processing system for annular, surrounding steel plant columns:

[0035] refer to Figure 1 The system adopts an integrated welding and positioning layout. The welding component 1, base 2, clamp 4, and positioning component 5 form a coordinated and interconnected structure, abandoning the traditional design of separating welding and positioning. The positioning mechanism and welding mechanism are integrated on the same base 2, eliminating the need for additional positioning supports, greatly simplifying the overall structure of the equipment and reducing the floor space required. At the same time, the clamp 4 and positioning component 5 are symmetrically arranged, symmetrically distributed with the welding head of the welding component 1 as the center. This ensures that after the two steel columns are joined, the welding head can be accurately aligned with the circumferential seam. The layout guarantees welding accuracy and avoids welding deviations caused by layout offsets. It also facilitates the operator's observation of the welding process, improving operational convenience.

[0036] Welding component 1 consists of a laser welding head and a support frame for the welding head. Its core design feature is the use of a laser welding head instead of a traditional arc welding head. Laser welding offers advantages such as concentrated energy, high welding speed, and excellent weld formation, effectively reducing welding thermal deformation and stress concentration in the steel column caused by high welding temperatures, thus preventing deformation from affecting subsequent installation. The support frame for the welding head employs a rigid structure and is fixedly connected to the base 2, ensuring the welding head remains stable during welding, preventing wobbling and guaranteeing consistent welding trajectory. Simultaneously, the support frame can adaptively adjust according to the height of the steel column, adapting to the welding needs of steel columns of different specifications and improving the equipment's versatility. Furthermore, the support frame's structural design incorporates protective functions, effectively blocking spatter generated during welding, protecting the welding head from damage, and extending the equipment's service life.

[0037] The base 2, serving as the load-bearing foundation of the entire system, is integrally cast from high-strength steel, ensuring strong structural rigidity and effectively supporting the weight of the steel column, clamps 4, and positioning components 5. This prevents deformation due to uneven stress during operation, guaranteeing overall operational stability. The symmetrically designed groove 3 at the top of the base 2 precisely matches the sliders 53 at the bottom of the clamps 4 and positioning components 5. The smooth inner wall of the groove 3 reduces friction during slider 53 sliding, allowing operators to flexibly adjust the distance between the two clamps 4 and positioning components 5 according to the diameter of the steel column. This adapts to processing steel columns of different specifications, solving the problem of traditional equipment's inability to flexibly adapt to various steel column sizes. Simultaneously, the precise design of the groove 3's depth and width limits the slider 53, preventing it from shifting during sliding and ensuring the positional accuracy of the clamps 4 and positioning components 5, laying the foundation for precise steel column positioning.

[0038] The clamp 4 is symmetrically arranged and embedded in the inner wall of the slide groove 3. Its core special design lies in its integrated connection with the positioning element 5. Positioning elements 5 are provided on opposite sides of the clamp 4, enabling the clamp 4 to not only support the steel column but also to accurately position it via the positioning elements 5. This achieves an integrated "support + positioning" function, simplifying the equipment structure, reducing the number of components, and lowering the probability of equipment failure. The inner wall of the clamp 4 adopts an arc-shaped design, conforming to the circumferential contour of the steel column, increasing the contact area and preventing surface damage due to excessive localized force during rotation. It also better secures the steel column, preventing radial displacement. Furthermore, the height of the clamp 4 can be adjusted according to the diameter of the steel column, ensuring that the center of the steel column and the center of the welding joint are on the same horizontal line, guaranteeing coaxiality of the weld and further improving welding accuracy.

[0039] refer to Figure 2 and Figure 3Positioning component 5 is the core component of the entire system for achieving precise positioning of the steel column and solving misalignment problems. It consists of subdivided components such as support frame 51, positioning frame 52, slider 53, electromagnetic component 54, groove 55, clamping plate 56, and connecting rod 57. The special designs of each subdivided component work together to form a comprehensive positioning constraint. Positioning frame 52, as the core positioning structure of positioning component 5, adopts a symmetrical splicing design. Two positioning frames 52 can be interlocked to form a ring-shaped wrapping positioning at the splicing point of the steel column. At the two ends of the two positioning frames 52 away from the support frame 51, clamping plates 56 and grooves 55 are symmetrically arranged. The outer wall of the clamping plate 56 matches the inner wall of the groove 55. This interlocking structure ensures that the two positioning frames 52 are precisely aligned when spliced, avoiding a decrease in positioning accuracy caused by splicing deviation. At the same time, the interlocking structure enhances the overall rigidity of the positioning frame 52 and prevents the positioning frame 52 from deforming when clamping the steel column. An electromagnetic component 54 is provided in the middle of the side of the positioning frame 52 away from the support frame 51. The electromagnetic component 54 can be activated by system control to generate magnetic force so that the two positioning frames 52 are tightly locked together without manual locking, which improves the convenience of operation. At the same time, the magnetic locking method can ensure that the positioning frame 52 has a uniform clamping force on the steel column, avoiding excessive local clamping force that could damage the steel column, or insufficient clamping force that could cause the steel column to misalign.

[0040] The positioning frame 52 has elastic elements 521 evenly spaced at its top, with retaining rings 522 at the top of each elastic element 521. Both sides of the retaining rings 522 have buffer pads 523. The elastic elements 521 are designed with self-adjusting functionality, automatically expanding and contracting according to the diameter of the steel column to ensure a tight fit between the retaining rings 522 and the outer wall of the steel column, adapting to steel columns of different diameters and improving the versatility of the positioning. The retaining rings 522 feature an arc-shaped design that conforms to the circumferential contour of the steel column, increasing the positioning contact area and further enhancing positioning stability. The buffer pads 523 are made of flexible, wear-resistant material, effectively buffering the vibrations generated during the rotation of the steel column, preventing surface scratches caused by hard contact between the steel column and the retaining rings 522, and simultaneously enhancing the friction between the retaining rings 522 and the steel column, helping to prevent circumferential slippage of the steel column.

[0041] The bottom of the positioning frame 52 is fixedly connected to a slider 53, which is slidably connected to the slide groove 3. This design allows the positioning frame 52 to slide along the slide groove 3 together with the clamp 4, which facilitates the adjustment of the positioning position and adapts to the docking positioning requirements of steel columns of different specifications. At the same time, the precise matching between the slider 53 and the slide groove 3 can ensure the accuracy of the movement trajectory of the positioning frame 52 and avoid positioning deviation caused by the offset of the positioning frame 52.

[0042] One end of the connecting rod 57 is fixedly connected to the side of the support frame 51, and the other end is fixedly connected to the side of the base 2. This rigid connection firmly connects the support frame 51 and the base 2 into a single unit, enhancing the load-bearing capacity and stability of the support frame 51. This prevents the support frame 51 from shaking or shifting during the rotation and welding of the steel column, ensuring reliable positioning. Furthermore, the length of the connecting rod 57 can be adjusted according to actual processing requirements, adapting to the positioning needs of steel columns of different specifications and improving the equipment's versatility.

[0043] refer to Figure 2 and Figure 4 The support frame 51 is located on the side of the positioning frame 52 and is fixedly connected to the side of the base 2 via a connecting rod 57. This fixing method enhances the stability of the support frame 51, prevents it from shaking during the rotation of the steel column, and ensures the reliability of the positioning. A ring block 512 is provided in the middle of the inner wall of the support frame 51. Limiting grooves 513 are equidistantly formed on the inner wall of the ring block 512. The positioning wheel 514 is located on the inner wall of the limiting groove 513. The design of the limiting groove 513 can fix and limit the positioning wheel 514, preventing it from shifting during rotation and ensuring that the positioning wheel 514 is always in circumferential contact with the steel column. At the same time, the equidistantly arranged limiting grooves 513 ensure that the positioning wheel 514 is evenly distributed, guaranteeing uniform force on the steel column and preventing deformation caused by excessive local force.

[0044] The ring block 512 has stop blocks 511 at both ends. The inner wall size of the stop block 511 is smaller than that of the ring block 512. This size difference design allows the stop block 511 to accurately abut against the end step surface of the steel column, achieving axial restraint of the steel column and preventing axial movement during rotary welding. This solves the problems of uneven weld gap and reduced weld quality caused by axial movement in traditional processing. At the same time, the stop block 511 is made of rigid material with a smooth surface treatment, which not only provides effective axial restraint but also avoids scratching the end surface of the steel column.

[0045] refer to Figure 4 and Figure 5 The positioning wheel 514 is a core component for preventing circumferential torsion of the steel column and assisting in its rotation. Its outer wall is equipped with a shallow-tooth anti-slip layer 5141, made of a flexible and wear-resistant material. The shallow tooth design increases the static friction with the outer wall of the steel column, effectively preventing circumferential slippage and misalignment during rotational stress and welding thermal deformation. It also avoids deep teeth scratching the steel column base material, protecting the surface quality of the steel column. A center wheel 517 is located in the center of the positioning wheel 514. A positioning hole 519 is formed in the center of the outer wall of the center wheel 517. The positioning hole 519 is designed to cooperate with the positioning assembly 518 to achieve precise positioning of the positioning wheel 514, preventing it from shifting during rotation and ensuring the precise fit between the positioning wheel 514 and the steel column.

[0046] The positioning wheel 514 has a guide shaft 515 on its side and a rotating shaft 516 in the middle of the guide shaft 515. The guide shaft 515 guides the rotation of the positioning wheel 514, ensuring that the positioning wheel 514 rotates along a fixed trajectory. The rotating shaft 516 is made of high-strength wear-resistant material, which can reduce the friction when the positioning wheel 514 rotates, extend the service life of the positioning wheel 514, and ensure that the positioning wheel 514 rotates smoothly, assisting the steel column to rotate smoothly and avoiding misalignment caused by jamming when the steel column rotates.

[0047] refer to Figure 5 , Figure 6 and Figure 7 The positioning assembly 518 includes arc-shaped locking posts 5181, symmetrically positioned at the top of the positioning ring 5182. Support rods 5183 are symmetrically fixed to the bottom of the positioning ring 5182. The arc-shaped design of the locking posts 5181 conforms to the contour of the center wheel 517, allowing them to precisely engage with the positioning hole 519 of the center wheel 517. This ensures accurate positioning of the positioning wheel 514, preventing it from shifting during rotation and ensuring that the positioning wheel 514 remains circumferentially in contact with the steel column, thus improving circumferential anti-torsion performance. The positioning ring 5182 connects the two locking posts 5181 into a single unit, enhancing the structural rigidity of the positioning assembly 518 and preventing deformation of the locking posts 5181 under stress. The support rods 5183 support the positioning ring 5182, ensuring the stability of the positioning assembly 518.

[0048] A positioning rod 5184 is inserted through the middle of the bottom end of the support rod 5183. The positioning rod 5184 is embedded in the inner wall of the movable groove 5185, which is symmetrically arranged at the top of the fixed seat 5186. This design allows the positioning rod 5184 to slide along the movable groove 5185, realizing the position adjustment of the positioning group 518 and adapting to positioning wheels 514 of different specifications. At the same time, the cooperation between the positioning rod 5184 and the movable groove 5185 can limit the positioning group 518, avoid positioning deviation caused by the displacement of the positioning group 518, and ensure the precise cooperation between the positioning group 518 and the positioning wheel 514.

[0049] Using hoisting equipment, the two steel columns to be joined are placed on symmetrically arranged clamps 4, so that the end stepped surfaces of the steel columns are in contact with the stops 511 of the support frame 51. The stops 511 achieve initial axial positioning of the steel columns to prevent axial displacement during placement. At the same time, the position of the steel columns is adjusted so that the joint of the two steel columns is aligned with the laser welding head of the welding part 1, ensuring that the welding head can be accurately aligned with the circumferential seam.

[0050] Adjust the position of the positioning frame 52 so that the retaining ring 522 at the top of the positioning frame 52 fits against the outer wall of the steel column. The elastic element 521 automatically expands and contracts according to the diameter of the steel column, ensuring that the retaining ring 522 fits tightly against the steel column. At the same time, the buffer pads 523 on both sides of the retaining ring 522 contact the surface of the steel column, providing cushioning and anti-slip effects. Adjust the position of the positioning wheel 514 so that the shallow toothed anti-slip layer 5141 on the outer wall of the positioning wheel 514 fits tightly against the circumference of the steel column, ensuring that the positioning wheel 514 can provide effective circumferential restraint on the steel column.

[0051] When the system control switch is activated, the electromagnetic component 54 of the positioning component 5 is activated. The electromagnetic component 54 generates magnetic force, attracting the two positioning frames 52 to move closer to each other. This causes the clamping plate 56 on one side of the positioning frame 52 to be precisely embedded into the groove 55 on the other side, achieving a tight engagement of the two positioning frames 52. This forms a ring-shaped radial clamping at the splice of the steel column, limiting the radial displacement of the steel column and preventing radial misalignment.

[0052] Check the positioning status of the positioning group 518 to ensure that the locking post 5181 is firmly locked into the positioning hole 519 of the center wheel 517, and that the positioning wheel 514 is accurately positioned in the limiting groove 513 without deviation; check the contact status between the stop block 511 and the step surface at the end of the steel column to ensure that the stop block 511 can effectively resist the steel column, achieve axial limitation, and prevent axial movement; check the contact status between the retaining ring 522 and the steel column to ensure that the extension and contraction force of the elastic element 521 is moderate, which can ensure the clamping effect without damaging the steel column.

[0053] The drive system of clamp 4 and positioning component 5 is activated, which drives the rotating wheel inside clamp 4 to rotate. The rotating wheel drives the steel column to rotate at a constant speed. At the same time, the positioning wheel 514 rotates synchronously under the drive of the steel column. The guide shaft 515 guides the rotation of the positioning wheel 514. The rotating shaft 516 reduces the friction when the positioning wheel 514 rotates, ensuring that the steel column rotates smoothly without jamming or offset. The shallow toothed anti-slip layer 5141 on the outer wall of the positioning wheel 514 increases the static friction with the steel column, preventing circumferential slippage and misalignment when the steel column rotates. At the same time, the locking structure of the positioning frame 52 and the clamping effect of the retaining ring 522 further limit the radial offset of the steel column, ensuring that the steel column always maintains coaxiality during rotation.

[0054] After the steel column rotates at a constant speed, the laser welding head of welding component 1 is activated. The laser welding head is aligned with the circumferential seam between the two steel column sections, and circumferential welding begins. During the welding process, the welding head remains fixed while the steel column rotates at a constant speed to achieve continuous welding of the circumferential seam. At the same time, the system monitors the rotation speed and welding progress of the steel column in real time to ensure that the welding speed matches the rotation speed and to ensure uniform weld formation.

[0055] During the welding process, each component of the positioning element 5 continuously plays a positioning role: the electromagnetic element 54 remains in the activated state to ensure that the positioning frame 52 is tightly engaged and to avoid positioning loosening caused by high welding temperature; the stop block 511 continuously abuts against the end of the steel column to prevent axial movement; the positioning wheel 514 continuously adheres to the steel column to prevent circumferential slippage; and the retaining ring 522, under the action of the elastic element 521, always holds the steel column tightly to avoid radial misalignment and to ensure the stability and welding accuracy of the welding process.

[0056] After the laser welding head completes the circumferential welding, the welding head and drive system are turned off, the steel column stops rotating, the electromagnetic component 54 is turned off, the magnetic force disappears, and the operator manually separates the two positioning frames 52, so that the clamping plate 56 is disengaged from the groove 55.

[0057] Adjust the position of the clamp 4 and the positioning component 5, push the slider 53 to slide along the slide groove 3, increase the distance between the two clamps 4, and make it easier to take out the welded steel column; at the same time, adjust the position of the positioning group 518 so that the clamp 5181 is disengaged from the positioning hole 519, and release the constraint of the positioning wheel 514 on the steel column.

[0058] The welded steel column is removed using hoisting equipment. The quality of the weld and the dimensional accuracy of the steel column are checked. After confirming that they meet the requirements, the equipment is cleaned and reset: debris is cleaned from the inner wall of the slide 3, and the components of the positioning part 5 are checked for wear, deformation, or other problems. Maintenance is carried out in a timely manner. The clamp 4 and positioning part 5 are reset to their initial positions, the system power is turned off, and the entire processing process is completed.

[0059] The automatic processing system for the circular steel plant column has completely solved the core problems such as radial misalignment, axial movement, and circumferential misalignment that exist in the traditional circular welding process of steel columns through the special design and coordinated cooperation of each structural component. At the same time, it has optimized the processing flow and improved processing efficiency and quality.

[0060] The system effectively solves three core misalignment problems during the rotational welding of steel columns through the omnidirectional positioning design of positioning component 5: First, the electromagnetic locking structure of positioning frame 52 and the clamping action of retaining ring 522 achieve radial clamping of the steel column, limiting radial displacement and completely resolving radial misalignment, ensuring the coaxiality of the two steel column sections. Second, the contact between the stop block 511 of support frame 51 and the stepped surface at the end of the steel column achieves axial limiting of the steel column, completely resolving axial movement and ensuring uniform circumferential gap. Third, the positioning action of the shallow toothed anti-slip layer 5141 of positioning wheel 514 and positioning group 518 increases the static friction with the steel column, preventing circumferential slippage and completely resolving circumferential misalignment, ensuring precise welding trajectory. The resolution of these three misalignment problems significantly improves the welding accuracy of the steel column, resulting in uniform weld formation, free from defects such as incomplete penetration, porosity, and slag inclusions, meeting the structural strength requirements of the steel plant column and laying a solid foundation for subsequent steel column installation.

[0061] The system adopts an integrated welding and positioning design, with all structural components working in tandem to automate the placement, positioning, rotation, and welding of steel columns. This eliminates the need for manual positioning and locking, significantly reducing manual labor and lowering the workload for operators. Furthermore, the use of a laser welding head offers faster welding speeds compared to traditional arc welding, and eliminates the need for frequent adjustments to welding parameters, further improving processing efficiency. The adjustable design of the clamps 4 and positioning components 5 adapts to the processing of steel columns of different specifications, eliminating the need to replace equipment or components, reducing equipment setup time, and increasing equipment utilization. Compared to traditional processing methods, this system can improve processing efficiency by more than three times, effectively shortening the steel column processing cycle and meeting the processing needs of large-scale steel plant column construction.

[0062] The positioning frame 52 has a retaining ring 522 with a buffer pad 523, and the shallow toothed anti-slip layer 5141 of the positioning wheel 514 is made of a flexible and wear-resistant material. The surface of the stop block 511 is smoothed, effectively preventing scratches on the surface of the steel column during positioning and rotation, and protecting the surface quality of the steel column. The concentrated energy of laser welding results in small welding thermal deformation, reducing deformation and stress concentration in the steel column caused by high welding temperatures, and preventing the steel column from being scrapped due to deformation. In addition, the system's precise positioning and stable welding reduce the occurrence of welding defects, increasing the product qualification rate of the steel column to over 99%, and reducing production costs and material waste.

[0063] The system base 2 is integrally cast from high-strength steel, which has a strong structural rigidity and can effectively bear the weight of each component, preventing deformation during equipment operation. The connection between each component adopts a rigid connection method to ensure a firm connection without loosening or displacement. The rotating shaft 516 of the positioning wheel 514 is made of high-strength wear-resistant material, which reduces friction during rotation and extends the service life of the positioning wheel 514.

[0064] The system is controlled by an automated system. Operators only need to perform simple operations such as initial equipment debugging, steel column placement, and subsequent steel column removal and equipment reset. No professional welding and positioning skills are required, which lowers the operating threshold and makes it easy for operators to get started quickly. The position adjustment of the clamp 4 and the positioning component 5 is achieved by sliding the slider 53 along the slide groove 3, which is simple and flexible. The automatic locking and unlocking of the electromagnetic component 54 does not require manual operation, further improving the convenience of operation and reducing the processing deviation caused by human error.

[0065] Traditional steel column ring welding equipment is mostly designed with fixed specifications, only suitable for processing steel columns of a single specification. When processing steel columns of different diameters and lengths is required, it is necessary to replace the equipment or adjust the core components, which is cumbersome, time-consuming, labor-intensive, and costly. This system, through the adjustable design of the clamp 4 and positioning component 5, allows the slider 53 to slide along the slide groove 3 to adjust the distance between the clamp 4 and the positioning component 5. The elastic component 521 can adapt to the diameter of the steel column, the fixing frame of the welding component 1 can be height adjusted, and the positioning group 518 can be position adjusted. It can adapt to the processing of steel columns of various specifications without the need to replace the equipment or components, greatly improving the adaptability of the equipment and reducing processing costs.

[0066] Traditional steel column welding positioning often relies on manual or simple mechanical positioning, resulting in low positioning accuracy and susceptibility to issues such as loosening and misalignment during the process. Especially during welding, the high temperatures can soften the positioning structure, further reducing reliability and leading to welding deviations. This system employs a positioning method combining an electromagnetic component 54 and mechanical clamping. The electromagnetic component 54 provides a stable clamping force, while the mechanical clamping structure ensures precise positioning. Simultaneously, the various components of the positioning element 5 work together to form a comprehensive positioning constraint, significantly improving positioning reliability. Even under the high temperatures of welding, it maintains stable positioning, preventing loosening and misalignment.

[0067] Traditional steel column welding often employs arc welding. Arc welding disperses energy, generating significant heat during the welding process and causing substantial thermal deformation of the steel column. This not only affects dimensional accuracy but also leads to stress concentration within the column, reducing its structural strength. This system utilizes a laser welding head. Laser welding concentrates energy, resulting in a smaller heat-affected zone, effectively reducing thermal deformation and stress concentration within the steel column. Simultaneously, the omnidirectional positioning constraint of the positioning component 5 effectively suppresses thermal deformation, ensuring both dimensional accuracy and structural strength of the steel column.

[0068] In traditional steel column welding, operators need to work at close range, and the spatter, high temperatures, and harmful gases generated during welding pose a threat to their personal safety. Furthermore, manual positioning and locking are prone to errors, leading to accidents such as steel column slippage and equipment damage. This system automates the process, eliminating the need for operators to be in close contact with the welding area, thus reducing the harm caused by spatter, high temperatures, and harmful gases. The automated positioning and locking processes avoid safety hazards caused by human error, significantly improving the safety of the entire process.

[0069] The quality of traditional steel column welding is greatly affected by the skill level and adherence to operating procedures of the operators. Significant differences in processing quality among different operators lead to unstable welding quality, making it difficult to meet engineering requirements. This system employs automated control and precise positioning. Welding parameters, rotation speed, and positioning accuracy are all precisely controlled by the system, avoiding quality deviations caused by human error and ensuring consistent processing quality for every steel column, thus improving the stability of processing quality.

[0070] The distance between the clamp 4 and the positioning element 5 is adjusted by the sliding groove 3 of the base 2 to fit the steel column to be processed; the two steel columns are placed on the clamp 4, and the stop block 511 achieves initial axial limitation; the electromagnetic element 54 is activated, causing the positioning frame 52 to engage, the retaining ring 522 to hold the steel column tightly, and the positioning wheel 514 to fit against the steel column, achieving precise positioning of the steel column; the drive system is activated, driving the steel column to rotate at a uniform speed, and the positioning wheel 514 rotates synchronously to ensure smooth rotation of the steel column; the laser welding head is activated, and circumferential welding is performed around the circumferential seam. During the welding process, the positioning element 5 continues to play a positioning role to ensure welding accuracy; after welding is completed, the electromagnetic element 54 is turned off, the positioning frame 52 is separated, the position of the clamp 4 is adjusted, the steel column is taken out, and the processing is completed.

[0071] The innovation of this core solution lies in integrating the triple positioning functions of "radial clamping, axial limiting, and circumferential anti-torsion" into the positioning component 5. It works in conjunction with the welding component 1, the base 2, and the fixture 4 to achieve integrated and automated welding and positioning. This not only completely solves the core misalignment problem in traditional processing, but also addresses pain points such as poor adaptability, low positioning reliability, and large thermal deformation. At the same time, it improves processing efficiency and quality. The structural design is simple, reliable, and feasible, fully meeting the automated processing requirements for the ring welding of steel plant columns.
