Abstract
Description
Technical Field
[0001] This invention relates to the field of welding tool technology, and in particular to a welding device for irregular steel structures. Background Technology
[0002] With the rapid development of modern architecture, bridges, heavy machinery, and aerospace, the application of irregular steel structures is becoming increasingly widespread. Due to their irregular shapes and complex spatial orientations, these structures place extremely high demands on their welding and manufacturing processes, aiming to ensure structural strength, sealing, and fatigue life. Welding quality directly affects the safety and reliability of the overall structure. Currently, significant difficulties exist in workpiece clamping and positioning during the welding of irregular steel structures. Traditional welding fixtures are mostly designed for regular workpieces, employing rigid clamps or simple V-blocks. When applied to irregular steel structures, the fit between the clamp and the workpiece surface is often poor, achieving only point or line contact, resulting in uneven clamping force distribution. This easily leads to unstable clamping, causing minute displacements or vibrations during welding, directly affecting the weld alignment accuracy. Simultaneously, rigid clamping can also cause localized stress concentration or even plastic deformation in thin-walled or complex cross-section components. Although some adjustable clamps exist, their adjustment freedom is limited, their automation level is low, and they cannot quickly and accurately adapt to ever-changing irregular contours, resulting in long welding preparation times and difficulties in aligning irregular steel structures. Therefore, current welding fixtures for irregular steel structures suffer from long alignment times and poor alignment accuracy. Summary of the Invention

[0023] This invention proposes a welding device 100 for irregular steel structures.
[0024] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the welding device 100 includes a mounting plate 1, a welding mechanism 3, and two clamping mechanisms 4. The mounting plate 1 extends laterally, and three adjusting mechanisms 2 are sequentially arranged on the top of the mounting plate 1 along the lateral direction. Each adjusting mechanism 2 can slide relative to the mounting plate 1 in the lateral direction. Each adjusting mechanism 2 includes a mounting frame 21321 and a mounting ring disposed on the top of the mounting frame 21321. The mounting frame 21321 is slidably connected to the mounting plate 1. The middle mounting ring is a first mounting ring 22, and the other two mounting rings are second mounting rings 23. The first mounting ring 22 forms a welding area. The welding mechanism 3 is disposed inside the first mounting ring 22 and can slide along the circumference of the first mounting ring 22. The two clamping mechanisms 4 are respectively disposed inside the two second mounting rings 23, and each clamping mechanism 4 can slide along the circumference of the corresponding second mounting ring 23. Each clamping mechanism 4 is used to clamp an irregular steel structure, so that the two irregular steel structures are joined together in the welding area for welding by the welding mechanism 3.
[0025] The non-standard steel structure welding device 100 of the present invention has three adjusting mechanisms 2 on the top of the mounting plate 1. Each adjusting mechanism 2 includes a mounting ring, the middle mounting ring being a first mounting ring 22 and the other two mounting rings being second mounting rings 23. The welding mechanism 3 is installed inside the first mounting ring 22, and two clamping mechanisms 4 are slidably disposed inside the two second mounting rings 23. The two clamping mechanisms 4 clamp two non-standard steel structures, and the position between the two non-standard steel structures can be adjusted by moving the corresponding adjusting mechanism 2, which can quickly align the two non-standard steel structures. By adjusting the sliding of the clamping mechanism 4 inside the second mounting ring 23, the angle of the non-standard steel structures can be adjusted to ensure higher docking accuracy. At the same time, by adjusting the position of the first mounting ring 22 on the mounting plate 1, the welding mechanism 3 can be moved to the docking point of the two non-standard steel structures for welding. By adjusting the position of the welding mechanism 3 inside the first mounting ring 22, the docking point of the two non-standard steel structures can be welded from multiple directions to ensure better welding effect.
[0026] It should be noted that, in this embodiment, the horizontal and vertical directions are respectively... Figure 1 The front-back and left-right directions.
[0027] Please combine Figure 1 , Figure 4 and Figure 5 In one embodiment, each clamping mechanism 4 includes multiple clamping components 41, which are arranged sequentially along the circumference of the corresponding mounting ring. Each clamping component 41 includes a first swing arm 411 and a clamping plate 412. One end of the first swing arm 411 is slidably connected to the inner side of the first mounting ring 22, and the clamping plate 412 is hinged to the side of the first swing arm 411 away from the first mounting ring 22. The side of each clamping plate 412 away from the first swing arm 411 is the clamping side. All clamping sides of each clamping mechanism 4 together form a clamping space for clamping irregular steel structures. Each clamping side is provided with a clamping airbag 4121, and the clamping airbag 4121 is filled with gel. Multiple anti-slip strips 4122 are spaced apart on the side of each clamping airbag 4121 away from the corresponding clamping plate 412.
[0028] By configuring the clamping mechanism 4 as multiple clamping components 41 distributed circumferentially, each clamping component 41 includes a first swing arm 411 and a clamping plate 412. The first swing arm 411 can swing to adjust the position of the clamping plate 412 so that the multiple clamping plates 412 cooperate with each other to clamp the irregular steel structure. The cooperation of multiple clamping plates 412 can adapt to irregular steel structures with different outer contours, thus improving versatility. Furthermore, a clamping airbag 4121 is provided on the clamping side of the clamping plate 412. The clamping airbag 4121 is filled with gel. When the clamping airbag 4121 contacts the irregular steel structure, the gel adapts to the shape of the irregular steel structure, thereby better conforming to the outer surface of the irregular steel structure and increasing the contact area. In addition, an anti-slip strip 4122 is provided on one side of the clamping airbag 4121 to increase the friction between it and the irregular steel structure, resulting in a better and more stable clamping effect.
[0029] Please see Figure 4 In one embodiment, in each clamping assembly 41, the first swing arm 411 includes an arc-shaped block 4111, a first hinge seat 4112, a first telescopic rod 4113, and a second hinge seat 4114. The arc-shaped block 4111 is slidably connected to the inner side of the first mounting ring 22. The first hinge seat 4112 is connected to the side of the arc-shaped block 4111 away from the first mounting ring 22. One end of the first telescopic rod 4113 is hinged to the side of the first hinge seat 4112 away from the arc-shaped block 4111. The other end of the first telescopic rod 4113 is hinged to the second hinge seat 4114. The clamping plate 412 is hinged to the side of the second hinge seat 4114 away from the first telescopic rod 4113.
[0030] The arc-shaped block 4111 matches the inner arc of the first mounting ring 22, and the first telescopic rod 4113 is hinged to the first hinge seat 4112, so that the first telescopic rod 4113 can rotate around the first hinge seat 4112 to adjust the angle. The first telescopic rod 4113 can extend and retract to adjust the position of the clamping plate 412. The clamping plate 412 can also rotate around the second hinge seat 4114, which further improves the flexibility of the clamping plate 412 and greatly enhances the adaptability of the clamping plate 412 to the outer contour of the irregular steel structure, achieving more flexible and stable clamping.
[0031] Furthermore, a traveling wheel is also provided on one side of the first hinge seat 4112 connected to the arc-shaped block 4111. The traveling wheel rolls against the inner side of the first mounting ring 22. When the traveling wheel rotates, it rolls along the inner side of the first mounting ring 22, thereby driving the arc-shaped ring to slide along the inner side of the first mounting ring 22.
[0032] Furthermore, power supply sliders are provided on both sides of the arc-shaped block 4111. The walking wheel and the power supply sliders are electrically connected. The inner side of the first mounting ring 22 is provided with a power supply groove that slides with the power supply slider. The power supply slider and the power supply groove work together to achieve coupled power supply, thereby providing electrical energy to the walking wheel to make the walking wheel rotate.
[0033] Please combine Figure 6 , Figure 7 and Figure 8 In one embodiment, the welding mechanism 3 includes a second swing arm 31 and a welding assembly 32. One end of the second swing arm 31 is slidably connected to the inner side of the second mounting ring 23. The welding assembly 32 includes a mounting frame 21321, a second telescopic rod 322, a welding torch 323, and two guide tubes 324. The mounting frame 21321 is hinged to the end of the second swing arm 31 away from the second mounting ring 23. A heating chamber 3211 is formed inside the mounting frame 21321, and a heating strip 3212 is disposed inside the heating chamber 3211. A fan 3213 communicating with the heating chamber 3211 is provided on the mounting frame 21321; one end of the second telescopic rod 322 is connected to the side of the mounting frame 21321 away from the second swing arm 31, and the welding torch 323 is connected to the other end of the second telescopic rod 322 away from the mounting frame 21321; two guide tubes 324 are both provided on the side of the mounting frame 21321 away from the second swing arm 31 and surround the second telescopic rod 322, and the two guide tubes 324 form a guide channel 3241 communicating with the heating chamber 3211.
[0034] It should be noted that the second swing arm 31 has the same structure as the aforementioned first swing arm 411, and will not be described in detail here.
[0035] In this embodiment, a heating chamber 3211 is formed within the mounting frame 21321, and a heating strip 3212 is installed within the heating chamber 3211. A fan 3213 is installed on one side of the mounting frame 21321, providing airflow into the heating chamber 3211. The airflow is heated by the heating strip 3212 to form hot air, which is then blown out through a guide channel 3241 formed by the guide cylinder 324. This allows the welding mechanism 3 to locally preheat the weld area before or during welding, which helps improve the welding quality of irregular steel structures. Furthermore, the second telescopic rod 322 facilitates adjustment of the welding torch 323's position, enabling welding at different weld locations and providing greater flexibility.
[0036] In one embodiment, a mounting plate 325 is connected to the outer periphery of the welding torch 323, and an elastic rod 326 is hinged to the mounting plate 325; the welding mechanism 3 also includes a vibration assembly 327, which includes a vibration generator 3271 and a resonance plate 3272. The resonance plate 3272 is disposed at the end of the elastic rod 326 away from the mounting plate 325, and the vibration generator 3271 is disposed on the side of the resonance plate 3272 connected to the elastic rod 326. The vibration generator 3271 is used to drive the resonance plate 3272 to vibrate.
[0037] Understandably, by setting up the vibration assembly 327, the resonance disk 3272 of the vibration assembly 327 can be attached to the irregular steel structure near the weld. As the welding operation proceeds, the vibration generated by the vibration generator 3271 drives the resonance disk 3272 to vibrate, thereby transmitting mechanical vibration to the weld position of the irregular steel structure. This helps to evenly transfer the heat of the molten pool generated at the weld, and also helps to disrupt the dendrite growth of the weld metal, promote the release of residual welding stress, and improve welding quality and efficiency. Furthermore, by setting the vibration assembly 327 on the elastic rod 326, the elastic rod 326 not only buffers the vibration of the vibration assembly 327, but also can rotate around the mounting plate 325, making it easy to adjust the position of the vibration assembly 327.
[0038] Please combine Figure 3 , Figure 9 and Figure 10 In one embodiment, in each adjustment mechanism 2, the top of the mounting bracket 21321 is provided with a longitudinally extending guide rail 211, the bottom of the mounting ring is provided with a guide block 24, and the guide block 24 forms a longitudinally extending guide channel. The bottom of the guide channel is open, and the guide rail 211 extends into the guide channel and slides in contact with the inner wall of the guide channel. Each guide block 24 is threaded with a locking rod 241 on one side of the transverse direction, and one end of the locking rod 241 extends into the guide channel and can abut against the guide rail 211.
[0039] By providing a guide rail 211 at the top of the mounting bracket 21321 and a guide block 24 that cooperates with the guide rail 211 at the bottom of the mounting ring, the mounting ring can slide along the guide rail 211, which can adjust the position of the irregular steel structure in the left and right directions, further improving the flexibility of the mounting ring; and after the mounting ring slides to the appropriate position, the guide block 24 can be locked relative to the guide rail 211 by the locking rod 241 abutting against the guide rail 211, thereby improving the stability of the irregular steel structure after docking.
[0040] In one embodiment, in each adjustment mechanism 2, the top of the guide block 24 is provided with a vertically extending mounting post 242, the bottom of the mounting ring is provided with a mounting cylinder 25, the mounting cylinder 25 forms a mounting groove with an opening at the bottom, and the top of the mounting post 242 extends into the mounting groove from the opening and slides into the groove wall of the mounting groove.
[0041] Understandably, by providing a mounting post 242 at the top of the guide block 24 and a mounting cylinder 25 at the bottom of the mounting ring, with the mounting post 242 extending into the mounting cylinder 25 and slidingly engaging with it, the mounting ring can also adjust its angle to accommodate more irregularly shaped steel mechanisms, further improving the flexibility of the adjustment mechanism 2.
[0042] In one embodiment, in each adjustment mechanism 2, a drive member and an active helical gear 243 are provided on the guide block 24, and a driven helical gear 251 that meshes with the active helical gear 243 is provided at the bottom of the mounting cylinder 25 and around the opening. The drive member is used to drive the active helical gear 243 to rotate, so as to drive the mounting cylinder 25 and the mounting surrounding mounting column 242 to rotate through the driven helical gear 251.
[0043] By setting an active helical gear 243 at the top of the guide block 24 and a driven helical gear 251 at the bottom of the mounting cylinder 25, the active helical gear 243 is driven to rotate by the driving component, thereby driving the driven helical gear 251 to rotate the mounting cylinder 25 and the mounting ring; no manual operation is required, reducing the intensity of manual labor.
[0044] Furthermore, a power socket is provided on one side of the guide block 24. The power socket is used to connect to an external power source to provide power to the drive component.
[0045] Furthermore, a conductive ring is provided on the outer side of the mounting post 242, and a conductive groove matching the conductive ring is provided on the inner side of the mounting cylinder 25. The conductive ring and the conductive groove work together to achieve coupled power supply; wherein the conductive ring is electrically connected to the power supply socket, and the conductive groove is electrically connected to the power supply slide rail 11.
[0046] Please combine Figure 3 and Figure 11 In one embodiment, a plurality of slide rails 11 are arranged longitudinally at intervals on the top of the mounting plate 1. Each slide rail 11 extends laterally and forms a slide groove. Each mounting bracket 21321 has a slider 212 at its bottom. The number of sliders 212 is the same as the number of slide grooves and they correspond one-to-one. Each slider 212 extends into the corresponding slide groove and can slide along the slide groove. Each mounting bracket 21321 has a drive wheel 213 at its bottom and at both opposite ends along the longitudinal direction. The drive wheel 213 rolls against the top of the mounting plate 1 and avoids the position of each slide rail 11.
[0047] By providing multiple slide rails 11 on the top of the mounting plate 1 and a slider 212 at the bottom of the mounting bracket 21321, the slider 212 extends into the groove formed by the slide rails 11, preventing the mounting bracket 21321 from shifting left and right and ensuring that the mounting bracket 21321 can only slide laterally. A drive wheel 213 is provided at the bottom of each mounting bracket 21321. When the drive wheel 213 rotates, it drives the entire mounting bracket 21321 to slide along the slide rails 11. No manual operation is required, and the degree of automation is high.
[0048] Furthermore, racks 13 are provided on the mounting plate 1 at positions corresponding to each drive wheel 213. The racks 13 extend laterally, and the drive wheels 213 mesh with the corresponding racks 13. The cooperation between the drive wheels 213 and the racks 13 prevents slippage when the drive wheels 213 rotate. When the drive wheels 213 are not rotating, the racks 13 limit their movement, preventing them from shifting and ensuring the positional accuracy of the entire adjustment mechanism 2.
[0049] Please see Figure 12 In one embodiment, any two adjacent mounting brackets 21321 and their opposite sides are two mounting sides. One mounting side is provided with a plurality of first guide posts 214 spaced apart along the longitudinal direction, and the other mounting side is provided with a plurality of second guide posts 215 spaced apart along the longitudinal direction. The plurality of first guide posts 214 and the plurality of second guide posts 215 are staggered along the longitudinal direction, and each first guide post 214 and its adjacent second guide post 215 are in sliding engagement.
[0050] Understandably, by setting staggered sliding cooperation of the first guide post 214 and the second guide post 215 on the side wall of the adjacent mounting bracket 21321, the first guide post 214 and the second guide post 215 cooperate with each other to play an auxiliary guiding and mutual restraint role when the adjustment mechanism 2 slides laterally, which can effectively prevent the single adjustment mechanism 2 from swaying when moving, and make the mounting bracket 21321 more stable during the sliding process.
[0051] Especially for large-scale irregular steel structures, the two adjacent mounting brackets 21321 are mutually constrained by the first guide post 214 and the second guide post 215, resulting in better structural strength, preventing deformation of a single adjustment mechanism 2, and making it more reliable.
[0052] Furthermore, multiple mounting blocks 12 are provided on both sides of the mounting plate 1 along the longitudinal direction, and the multiple mounting blocks 12 on the same side are evenly distributed at transverse intervals. Each mounting block 12 is provided with mounting screw holes. By providing mounting blocks 12, it is convenient to install and fix the mounting plate 1 during use, and the mounting plate 1 can be fixed by bolts or the like.
[0053] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
