Description

Technical Field

[0001] This application relates to the technical field of arc-shaped I-beams for arched protective airtight doors, and more particularly to a welding jig for arc-shaped I-beams. Background Technology

[0002] The inner and outer shapes of the arched protective airtight door both exhibit a certain curvature. The internal curved I-beams used for support and reinforcement can only be obtained through splicing and welding. Currently, curved I-beams are generally composed of three parts welded together: an inner curved plate, an outer curved plate, and a web plate. During welding, it is necessary to ensure the relative positions between the inner curved plate, the outer curved plate, and the web plate. Traditional welding methods typically involve first roughly splicing and arranging the inner curved plate, the outer curved plate, and the web plate, and then the welder visually determines the relative positions between the three parts before welding. However, in the actual welding process, due to the lack of precise and effective positioning methods, the relative positions between the inner curved plate, the outer curved plate, and the web plate are difficult to control accurately. This results in a deviation between the curvature of the welded curved I-beam and the requirements of the drawings, thereby affecting the structural stability and protective effect of the arched protective airtight door. Summary of the Invention

[0003] In view of this, this application proposes an arc-shaped I-beam welding jig, comprising: a worktable and two or more positioning components;

[0004] Two or more positioning components are fixedly mounted on the worktable. The two or more positioning components are distributed in an arc shape, and the central angle formed by each two adjacent positioning components and the center of the arc is equal.

[0005] Two or more positioning components each include: a limit block, a pad block, and a fixing block; the limit block and the fixing block are both fixedly set on the worktable, and the fixing block and the limit block are spaced apart, which is suitable for limiting the I-beam between the limit block and the fixing block;

[0006] The pad is fixedly installed on the workbench and located between the limit block and the fixing block, which is suitable for providing height support for the I-beam;

[0007] The fixing block, pad block, and limit block are arranged sequentially along the radius of the arc, with the fixing block located on the side closest to the center of the arc.

[0008] In one possible implementation, an adjustment component is also included; the adjustment component is disposed on the fixed block and is movable in a direction toward or away from the block, suitable for adjusting the curvature of the I-beam.

[0009] In one possible implementation, the adjusting assembly includes a bolt and a nut; the nut is fixedly mounted on the fixing block and located on the side of the fixing block facing the pad, and the bolt passes through the fixing block and is threadedly connected to the nut.

[0010] In one possible implementation, the main body of the fixing block is a U-shaped steel structure, and the opening of the fixing block faces the pad block, with the nut fixed at the opening of the fixing block.

[0011] In one possible implementation, a preset distance is provided between the fixed block and the limiting block.

[0012] In one possible implementation, there are nine positioning components, and the central angle formed by each pair of adjacent positioning components and the center of the arc is 7.5°.

[0013] Beneficial effects of this application

[0014] This application achieves precise positioning of the arc-shaped I-beam during welding by setting two or more positioning components equidistantly distributed in an arc shape. These components work collaboratively to avoid deviations caused by difficulty in controlling the position, as is common in traditional welding methods. This ensures that the welded arc-shaped I-beam meets the dimensions and relative position requirements of the drawings. The welding fixture of this application is easy to operate. The inner arc plate, outer arc plate, and web plate required for welding the I-beam are placed on the welding fixture, with each component positioned between a fixed block and a limiting block. The inner arc plate is tightly fitted to the side wall of the fixed block, and the outer arc plate is tightly fitted to the limiting block. The web plate is placed on a pad between the inner and outer arc plates. Positioning is achieved through simple placement, allowing for welding of all three components without the need for significant time and effort to adjust their relative positions. The entire process is simple and quick, reducing operational difficulty and improving work efficiency. Furthermore, the welding fixture of this application has a simple and robust structure, is reusable, and has low processing costs.

[0025] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0026] This application proposes an arc-shaped welding jig for I-beams, suitable for providing positioning support when welding 400mm I-beams; such as Figures 1 to 4As shown, the system includes: a worktable 100 and two or more positioning components; the two or more positioning components are fixedly mounted on the worktable 100, and the two or more positioning components are distributed in an arc shape, with the central angle formed by each two adjacent positioning components and the center of the arc being equal; each of the two or more positioning components includes: a limiting block 210, a pad block 220, and a fixing block 230; the limiting block 210 and the fixing block 230 are both fixedly mounted on the worktable 100, and the fixing block 230 and the limiting block 210 are spaced apart, which is suitable for limiting the I-beam 400 between the limiting block 210 and the fixing block 230; the pad block 220 is fixedly mounted on the worktable 100 and located between the limiting block 210 and the fixing block 230, which is suitable for providing height support for the I-beam 400; the fixing block 230, the pad block 220, and the limiting block 210 are arranged sequentially along the radial direction of the arc, and the fixing block 230 is located on the side closer to the center of the arc.

[0027] It should be noted that the worktable 100 is suitable for providing a stable mounting surface for two or more positioning components. Multiple positioning components are evenly distributed in an arc shape along the length of the worktable 100, providing stable support for the I-beam 400. The arc-shaped distribution of the positioning components allows them to better conform to the curvature of the I-beam 400, providing uniform support and positioning, ensuring the I-beam 400 is in the correct curvature state during welding, and improving the accuracy of the curvature of the welded I-beam 400. The limiting block 210 is used to limit the outer arc plate 420 of the I-beam 400. The relative position of the limiting block 210 is consistent with the outer curvature of the outer arc plate 420 of the I-beam 400, thus ensuring that the outer arc plate 420 of the I-beam 400 and the side wall of the limiting block 210 facing the fixing block 230 are tightly fitted, thereby preventing the I-beam 400 from being placed... If displacement occurs during placement or welding, the fixing block 230 is used to limit the inner arc plate 410 of the I-beam 400. The relative position of the fixing block 230 is consistent with the inner arc of the inner arc plate 410 of the I-beam 400, so that the inner arc plate 410 of the I-beam 400 and the side wall of the fixing block 230 facing the limiting block 210 are tightly fitted. The fixing block 230 and the limiting block 210 cooperate to form a double-sided limiting of the I-beam 400, which effectively avoids the welding deviation caused by the movement of the I-beam 400 during welding and ensures the accuracy of the relative position of the I-beam 400 after welding. The pad block 220 is used to provide height support for the web plate 430 of the I-beam 400, which avoids the welding deviation caused by the sagging or deformation of the web plate 430 due to its own weight or welding stress during welding, thereby ensuring the accuracy of the relative position between the web plate 430, the outer arc plate 420, and the inner guard plate.

[0028] This application achieves precise positioning of the curved H-beam 400 during welding by setting two or more positioning components equidistantly distributed in an arc shape. These components work together to ensure accurate positioning of the relative position of the H-beam 400. This effectively avoids deviations caused by difficulty in controlling the position in traditional welding methods, ensuring that the curvature of the welded H-beam 400 conforms to the dimensions and relative position requirements of the drawings. The welding fixture of this application is easy to operate. The inner arc plate 410, outer arc plate 420, and web plate 430 required for welding the H-beam 400 are placed on the welding fixture. All three components are fixed... The fixing block 230 and the limiting block 210 are positioned between each other; the inner arc plate 410 is tightly fitted to the side wall of the fixing block 230, the outer arc plate 420 is tightly fitted to the limiting block 210, and the web plate 430 is placed on the pad 220 and located between the inner arc plate 410 and the outer arc plate 420. The positioning can be completed by simple placement, and then the three can be welded. There is no need to spend a lot of time and effort to adjust the relative positions between the inner arc plate 410, the outer arc plate 420 and the web plate 430. The whole process is simple and quick, reducing the difficulty of operation and improving the work efficiency. Moreover, the welding jig structure of this application is simple and strong, can be reused, and has low processing cost.

[0029] In one possible implementation, an adjusting component 300 is also included. The adjusting component 300 is disposed on the fixed block 230 and is movable in a direction toward or away from the pad block 220, suitable for adjusting the curvature of the I-beam 400. It should be noted that the adjusting component 300 is disposed through the fixed block 230, and one end of the adjusting component 300 penetrating the fixed block 230 abuts against the inner arc plate 410 of the I-beam 400. When the adjusting component 300 moves in a direction toward the pad block 220, it pushes the inner arc plate 410 of the I-beam 400 toward the pad block 220, thereby increasing the curvature of the I-beam 400. When the adjusting component 300 moves in a direction away from the pad block 220, the inner arc plate 410 of the I-beam 400 moves in the opposite direction to the pad block 220 under its own rigidity, thereby decreasing the curvature of the I-beam 400.

[0030] In one possible implementation, such as Figure 1 , Figure 3 As shown, the adjustment assembly 300 includes a bolt 310 and a nut 320; the nut 320 is fixedly mounted on the fixing block 230 and located on the side of the fixing block 230 facing the pad block 220, and the bolt 310 passes through the fixing block 230 and is threadedly connected to the nut 320.

[0031] It should be noted that the design of the nut 320 being fixedly mounted on the fixing block 230 provides a stable connection point for the bolt 310. The nut 320 and bolt 310 are matched, and the bolt 310 passes through the fixing block 230 and is threadedly connected to the nut 320. The bolt 310 can be screwed in and out of the threaded hole of the nut 320 along its length. When the bolt 310 is screwed into the nut 320, the bolt 310 abuts against the inner arc plate 410 of the I-beam 400. The bolt 310 converts its linear motion into a thrust on the inner arc plate 410 of the I-beam 400, thereby pushing the inner arc plate 410 of the I-beam 400 away from the fixing block 230. The inner arc plate 410 of the I-beam 400 expands outward under the thrust of the bolt 310, which in turn stretches the web plate 430 and the arc plate accordingly, thereby increasing the curvature of the I-beam 400. Conversely, when the bolt 310 is unscrewed, the thrust of the bolt 310 on the inner arc plate 410 of the I-beam 400 decreases, and the inner arc plate 410 of the I-beam 400 moves toward the fixing block 230 under its own elasticity, thereby reducing the curvature of the I-beam 400. By controlling the degree to which the bolt 310 is screwed in and out, the moving distance of the inner arc plate 410 of the I-beam 400 can be precisely controlled, thereby precisely adjusting the curvature of the I-beam 400 to achieve the required size and shape requirements.

[0032] Furthermore, the nut 320 is fixedly connected to the fixing block 230 by welding, and the screw hole of the nut 320 is set facing the pad block 220. The bolt 310 adopts the existing M30X100 bolt, and the nut 320 adopts the existing M30 nut.

[0033] In one possible implementation, the main body of the fixing block 230 is a U-shaped steel structure, with the opening of the fixing block 230 facing the pad block 220; the nut 320 is fixedly installed at the opening of the fixing block 230. It should be noted that the U-shaped design of the fixing block 230 provides installation space for the nut 320. The nut 320 is fixedly installed at the opening of the fixing block 230, forming a flat supporting plane together with the fixing block 230. This supporting plane is in close contact with the inner arc plate 410 of the I-beam 400, ensuring that the arc plate of the I-beam 400 is evenly stressed, effectively avoiding local stress concentration caused by uneven stress, thus ensuring the structural integrity of the I-beam 400, improving welding quality, and preventing damage to the inner protective plate of the I-beam 400 caused by the nut 320 protruding from the fixing block 230.

[0034] In one possible implementation, a preset distance is provided between the fixing block 220 and the limiting block 210. It should be noted that the design of the preset distance provides operating space for adjusting the curvature of the I-beam 400. The operator can place the I-beam 400 on the fixture and make fine adjustments, avoiding operation restrictions due to limited space.

[0035] The preset distance design provides sufficient operating space for the adjustment component 300 when adjusting the curvature of the I-beam 400, enabling the adjustment component 300 to effectively adjust the curvature of the I-beam 400 within this preset distance range, thus avoiding the inability to achieve the expected curvature adjustment due to the small distance between the fixed block 220 and the limiting block 210.

[0036] Furthermore, the preset distance ranges from 275mm to 285mm. Preferably, the preset distance is 280mm.

[0037] Furthermore, the distance between the fixing block 220 and the pad 230 is equal to the distance between the limiting block 210 and the pad 230.

[0038] In one possible implementation, the main body of the worktable 100 is a rectangular plate structure, and the limiting block 210, pad block 220 and fixing block 230 are all fixedly mounted on the worktable 100 by welding.

[0039] In one possible implementation, there are nine positioning components, and the central angle formed by each pair of adjacent positioning components and the center of the arc is 7.5°.

[0040] It should be noted that the nine positioning components are evenly distributed along the arc to form continuous and smooth support points, which realizes the arc-shaped positioning of the I-beam 400, avoids the risk of deformation of the I-beam 400 due to local stress, and ensures the arc accuracy of the I-beam 400. The welding jig of this application simplifies the alignment and fixing process between the outer arc plate 420, inner arc plate 410 and web plate 430 of the I-beam 400 by pre-positioning, reduces the time for manual adjustment, ensures the consistency of the arc of the welded arc I-beam 400, and improves work efficiency.
