Description

Technical Field

[0001] This utility model relates to the field of integrated welding technology, and in particular to an integrated welding structure for an arc-starting plate used in submerged arc welding of steel structures. Background Technology

[0002] Submerged arc welding is a consumable electrode arc welding method in which an electric arc burns under a layer of flux to achieve welding of workpieces. An arc-starting plate is a temporary or permanent auxiliary component set up in welding operations to solve the quality defects that are prone to occur at the arc-starting and arc-extinguishing ends of the weld. An integrated arc-starting plate welding structure for steel structure submerged arc welding is a welding construction system designed for the characteristics of steel structure submerged arc welding process, which integrates the arc-starting functional component with the main weld area of ​​the steel structure through a preset connection method into a unified stress unit.

[0003] Submerged arc welding (SAW) is one of many welding methods used in the integrated welding structure of submerged arc welding for steel structures. SAW has advantages such as high production efficiency and stable welding quality. In the prior art, before welding, the arc-starting plate needs to be manually held and welded to the side wall of the workpiece. However, manual holding affects the welding quality, and it is difficult to ensure absolute stability of the arc-starting plate. Even slight shaking or positional displacement will change the relative position between the arc-starting plate and the workpiece, which will result in uneven weld gap during welding. The prior art uses special clamps to fix the arc-starting plate to prevent positional displacement and ensure the uniformity of weld gap. At the same time, installation and removal are convenient and quick. However, the integrated welding of arc-starting plates in the prior art has poor dimensional compatibility and cannot match the fitting requirements of arc-starting plates of different thicknesses. When using an incompatible arc-starting plate, the welding torch will deviate from the center when aligning with the bevel, resulting in one-sided undercut of the weld. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides an integrated welding structure for submerged arc welding of steel structures, aiming to improve the problems of poor dimensional compatibility, inability to match the fitting requirements of arc-starting plates of different thicknesses, and undercut caused by misalignment of the welding torch when it is aligned with the center in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated welding structure for submerged arc welding of steel structures, comprising a steel plate to be welded, a clamping mechanism installed on the left side of the steel plate to be welded, the clamping mechanism being used to clamp the arc-starting plate, and an anti-shrinkage mechanism slidably connected to the left side of the steel plate to be welded, the anti-shrinkage mechanism being used to fix the width of the weld gap; the clamping mechanism includes a large outer shell, the large outer shell being installed on the right side of the steel plate to be welded, a plurality of sliding columns being fixedly connected to the left side of the inner wall of the large outer shell, and a plurality of clamping heads being slidably connected to the inner wall of the side adjacent to the front sliding columns, a driving block being fixedly connected to the right side of each clamping head, and a driving component being installed on the right side of the driving block.

[0006] As a further description of the above technical solution: the drive assembly includes a motor, which is fixedly connected to the rear side of the inner wall of the large outer shell. A gear is fixedly connected to the output end of the motor, and a rack cylinder is meshed with the bottom of the gear. A push cone plate is fixedly connected to the left end of the rack cylinder.

[0007] As a further description of the above technical solution: the anti-shrinkage mechanism includes a conical head, the outer wall of which is slidably connected to the inside of the steel plate to be welded, a push rod is fixedly connected to the left side of the conical head, a push block is fixedly connected to the left side of the push rod, and a small outer shell is slidably connected to the upper and lower sides of the push block, and a motion component is installed inside the small outer shell.

[0008] As a further description of the above technical solution: the motion component includes a second motor, the second motor is fixedly connected to the inner wall of the small outer shell on its upper and lower sides, a second gear is fixedly connected to the output end of the second motor, a third gear is meshed with the front side of the outer wall of the second gear, and a threaded rod is fixedly connected to the middle of the third gear.

[0009] As a further description of the above technical solution: a plurality of large magnets are fixedly connected to the left side of the large outer shell, and the left side of the large magnets is installed on the right side of the steel plate to be welded.

[0010] As a further description of the above technical solution: a plurality of small magnets are fixedly connected to the right side of the small outer shell, and the right side of the small magnets is installed on the left side of the steel plate to be welded.

[0013] As a further description of the above technical solution: multiple universal wheel clamping plates are fixedly connected to the bottom of the lifting platform, and each universal wheel clamping plate is rotatably connected to a wheel.

[0014] As a further description of the above technical solution: a utility table is installed at the bottom of the anti-shrinkage mechanism, and a welding torch is placed on the front side of the top of the utility table.

[0015] This utility model has the following beneficial effects: 1. In this utility model, when it is necessary to clamp the arc-starting plate, as the drive component moves, the protrusion on the push cone plate slides inside the drive block, causing the drive block to drive the clamping head to move closer to each other under the guidance of the sliding column, thereby clamping the arc-starting plate. The clamping mechanism adopts an upper and lower clamping structure, which can be adapted to arc-starting plates of different sizes and effectively reduces the weld undercut phenomenon caused by welding off-center.

[0016] 2. In this utility model, as the moving component drives the push block to slide to the right, the push rod and the conical head fixed to the push block move to the right together. The depth of the conical head entering the welded steel plate is determined by controlling the start time of the motor, which in turn determines the width between the fixed steel plates. This effectively prevents the problem of the weld seam on one side gradually becoming smaller during the welding of the steel plates. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an integrated arc-starting plate welding structure for submerged arc welding of steel structures, comprising a steel plate to be welded 1, a clamping mechanism 2 installed on the left side of the steel plate to be welded 1, the clamping mechanism 2 being used to clamp the arc-starting plate, and an anti-shrinkage mechanism 3 slidably connected to the left side of the steel plate to be welded 1, the anti-shrinkage mechanism 3 being used to fix the width of the weld gap; the clamping mechanism 2 includes a large outer shell 201, the large outer shell 201 being installed on the right side of the steel plate to be welded 1, a plurality of sliding groove columns 202 being fixedly connected to the left side of the inner wall of the large outer shell 201, and a plurality of clamping heads 203 being slidably connected to the inner wall of the side adjacent to the front sliding groove column 202, and a driving block 2 being fixedly connected to the right side of each clamping head 203. 04. A drive assembly 205 is installed on the right side of the drive block 204. The drive assembly 205 includes a motor 2051. The motor 2051 is fixedly connected to the rear side of the inner wall of the large outer shell 201. A gear 2052 is fixedly connected to the output end of the motor 2051. A rack cylinder 2053 is meshed with the bottom of the gear 2052. A push cone plate 2054 is fixedly connected to the left end of the rack cylinder 2053. Multiple large magnets 4 are fixedly connected to the left side of the large outer shell 201. The left side of the large magnets 4 is installed on the right side of the steel plate 1 to be welded. An arc-starting plate 6 is installed on the right side of the steel plate 1 to be welded. The upper and lower sides of the arc-starting plate 6 are installed on the adjacent side of the clamping head 203. Specifically, when the arc-initiating plate needs to be clamped, the motor 2051 is started. The gear 2052 fixed to the output end of the motor 2051 rotates with the start of the motor. When the gear 2052 rotates, the rack cylinder 2053 meshing with it will move to the right. The push cone plate 2054 fixed to the rack cylinder 2053 will also move to the right synchronously. The protrusion on the push cone plate 2054 slides inside the driving block 204, causing the upper and lower driving blocks 204 to move closer to each other along the guide groove column 202 fixed inside the large outer shell 201. Since the clamping head 203 is fixedly connected to the driving block 204, the upper and lower clamping heads 203 will move closer to each other along the guide rail 202 with the driving block 204 to clamp the arc-starting plate 6. At the same time, the large magnet 4 fixed on the left side of the large outer shell 201 will attract the right side of the steel plate 1 to be welded, further enhancing the fixing effect. The clamping mechanism 2 adopts an upper and lower clamping structure, which, together with the attraction of the large magnet 4, can adapt to arc-starting plates of different sizes, effectively reducing the weld undercut phenomenon caused by welding off-center and improving the welding quality.

[0021] Reference Figure 5 The anti-shrinkage mechanism 3 includes a conical head 301. The outer wall of the conical head 301 is slidably connected to the inside of the steel plate 1 to be welded. A push rod 302 is fixedly connected to the left side of the conical head 301. A push block 303 is fixedly connected to the left side of the push rod 302. A small outer shell 304 is slidably connected to the upper and lower sides of the push block 303. A motion component 305 is installed inside the small outer shell 304. The motion component 305 includes a second motor 3051. The second motor 3051 is fixedly connected to the upper and lower sides of the inner wall of the small outer shell 304. A second gear 3052 is fixedly connected to the output end of the second motor 3051. A third gear 3053 is meshed with the front side of the outer wall of the second gear 3052. A threaded rod 3054 is fixedly connected to the middle of the third gear 3053. A plurality of small magnets 5 are fixedly connected to the right side of the small outer shell 304. The right side of the small magnets 5 is installed on the left side of the steel plate 1 to be welded.

[0022] Specifically, when it is necessary to adjust the size of the weld gap between the front and rear steel plates, motor 2 3051 is started. Gear 2 3052, which is fixed to the output end of motor 2 3051, will rotate as the motor starts. Gear 3 3053, which meshes with gear 2 3052, will rotate synchronously. Since threaded rod 3054 is fixedly connected to gear 3 3053, threaded rod 3054 will rotate inside small housing 304 as gear 3 3053 rotates. As threaded rod 3054 rotates, push block 303, which is threadedly connected to it, will move within small housing 304. The inside slides to the right, which in turn drives the push rod 302, which is fixed to the push block 303, to move to the right together. At this time, the conical head 301, which is fixed to the push rod 302, will slide in the weld seam of the steel plate. By controlling the start time of the motor, the width of the gap held by the conical head 301 can be precisely controlled. At the same time, the small magnet 5 fixed to the right side of the small outer shell 304 can attract the steel plate and enhance the overall stability. This structure effectively prevents the problem of the weld seam gradually becoming smaller on one side due to uneven force during the welding process of the steel plate, and ensures the uniformity of the weld seam.

[0023] Reference Figure 1 and Figure 2 The clamping mechanism 2 is equipped with a motor controller 7 on its top and a lifting platform 8 is fixedly connected to its bottom. Multiple universal wheel clamping plates 9 are fixedly connected around the bottom of the lifting platform 8. Wheels 10 are rotatably connected inside the universal wheel clamping plates 9. A miscellaneous table 11 is installed at the bottom of the anti-shrinkage mechanism 3. A welding torch 12 is placed on the front side of the top of the miscellaneous table 11.

[0024] Specifically, the core function of the motor controller 7 is to control the start and stop of the relevant motors, thereby achieving precise start and stop control of the equipment operation. The lifting platform 8, fixed at the bottom of the clamping mechanism 2, is mainly used to adjust the height of the clamping mechanism 2 to adapt to steel plates 1 or arc-starting plates of different heights, ensuring accurate clamping position. The universal wheel clamping plate 9, which cooperates with the clamping wheels 10, can finely adjust the horizontal position of the clamping mechanism 2 through the flexible rotation characteristics of the universal wheels, further improving the accuracy of clamping alignment. In addition, the miscellaneous table 11, which supports the anti-shrinkage mechanism 3, not only serves to support the anti-shrinkage mechanism 3, but also acts as a storage platform to store miscellaneous items required during the welding process, such as welding guns 12 and welding rods, making it convenient for operators to access and improving operational convenience.

[0025] Working principle: When the arc-initiating plate needs to be clamped, as the motor 2051 starts, the gear 2052 fixed to the output end of the motor 2051 rotates. As the gear 2052 rotates, the rack cylinder 2053 meshing with it moves to the right. Because the pushing cone plate 2054 is fixed to the rack cylinder 2053, it moves to the right along with the rack cylinder 2053. The protrusions on the pushing cone plate 2054 slide inside the driving block 204. The upper and lower driving blocks 204 move closer to each other along the guide of the sliding column 202 fixed inside the large outer shell 201. Since the clamping head 203 is fixed to the driving block 204, the upper and lower clamping heads 203 also move closer to each other along the guide of the sliding column 202 as the driving blocks 204 move closer to each other, thereby achieving the purpose of clamping the arc-starting plate 6. Because the clamping head 203 of the clamping mechanism 2 adopts an upper and lower clamping structure, it can be adapted to arc-starting plates of different sizes, effectively reducing the weld undercut phenomenon caused by welding off-center. When it is necessary to adjust the size of the weld gap in the front and rear steel plates, start motor 2 3051. As motor 2 3051 starts, gear 2 3052, which is fixed at the output end of motor 2 3051, rotates. Gear 3 3053, which meshes with gear 2 3052, rotates synchronously with gear 2 3052. Because threaded rod 3054 is fixedly connected to gear 2 3052, threaded rod 3054 will rotate inside small housing 304 as gear 3053 rotates. As threaded rod 3054 rotates, it drives push block 303 to slide to the right inside small housing 304. With the movement of push block 303, push rod 302, which is fixed to push block 303, moves to the right together. Conical head 301, which is fixed to push rod 302, slides inside the weld seam of the steel plate. The duration of motor start determines the width of the gap held by conical head 301, thereby preventing the weld seam on one side from gradually shrinking during the steel plate welding process.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
