A limiting mechanism for welding steel structure materials

Abstract

This utility model discloses a limiting mechanism for welding steel materials in steel structures, relating to the field of steel structure welding technology. It includes a clamping platform with sliding plates symmetrically slidably mounted on both sides. A fixing frame is fixedly mounted on each side of the top of the sliding plates near the clamping platform. A flipping plate is rotatably mounted inside the fixing frame. The system also includes a flipping mechanism located on top of the sliding plates and used to adjust the angle of the flipping plate. By incorporating a flipping mechanism, where an electric push rod extends and retracts to drive a drive shaft and drive arm, the flipping plate rotates around the clamping block, achieving arbitrary angle adjustment within the 0-90° range. This solves the problem of insufficient angle adjustment flexibility in the prior art, where most equipment can only achieve horizontal or small-angle tilt fixation, failing to meet the requirements of complex working conditions such as vertical welding and large-bevel welding.

Description

Technical Field

[0001] This utility model relates to the field of steel structure welding technology, and specifically to a limiting mechanism for welding steel materials in steel structures. Background Technology

[0002] In the field of steel structure processing, workpieces need to be fixed by limiting mechanisms during steel welding to ensure welding accuracy and operational safety. Existing welding limiting devices have the following shortcomings: First, they have poor adaptability to steel of different lengths and shapes, especially for irregularly shaped steel (such as L-beams and I-beams), where the clamping structure cannot tightly fit the workpiece surface, easily leading to loosening or positioning misalignment; second, they lack flexibility in angle adjustment, with most devices only capable of horizontal or small-angle tilting fixation, failing to meet the needs of complex working conditions such as vertical welding and large-bevel welding; third, they have high maintenance costs, as the core clamping components are mostly integrated designs, requiring replacement of the entire unit after partial wear, increasing equipment operating costs.

[0003] To address the aforementioned issues, this utility model proposes a limiting mechanism for welding steel structures. Through modular design, it achieves efficient coordination of length adaptation, angle adjustment, and irregular clamping, while optimizing structural flexibility and ease of maintenance to meet the needs of diverse welding scenarios. Utility Model Content

[0004] The purpose of this utility model is to provide a limiting mechanism for welding steel materials in steel structures, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A limiting mechanism for welding steel materials in a steel structure includes a clamping platform. Sliding plates are symmetrically slidably mounted on both sides of the clamping platform. A fixing frame is fixedly mounted on each side of the top of the sliding plates near the clamping platform. A flipping plate is rotatably mounted inside each fixing frame. The mechanism also includes a flipping mechanism located on top of the sliding plates and used to adjust the angle of the flipping plates.

[0007] A telescopic assembly is disposed at the bottom of the clamping platform and is used to adjust the lateral spacing of the sliding plates.

[0008] A further improvement of this utility model is that the flipping mechanism includes an adjustable clamping component and a second fixing frame. The second fixing frame is fixedly installed on both sides of the top of the sliding plate away from the clamping table. A fixing ring is rotatably installed inside the second fixing frame. An electric push rod is fixedly installed at the end of the fixing ring away from the flipping plate. The output end of the electric push rod passes through the fixing ring and is fixedly installed with a bushing. A drive shaft is rotatably installed inside the bushing. A drive arm is fixedly installed on the side of the flipping plate near the electric push rod and is fixedly installed with the drive shaft. The adjustable clamping component is located above the clamping table and is used to fix steel materials of different shapes.

[0009] Using the above technical solution, when the steel is placed on the clamping table, the telescopic component can drive the sliding plate to slide along the clamping table according to the length of the steel, so that the flipping plate at the top of the sliding plate is aligned with the part of the steel that needs to be fixed, completing the initial position alignment. If the steel needs to be welded at an angle or vertically, the electric push rod one on the fixed frame two can be activated, and the drive shaft can be rotated through the bushing on the output end of the electric push rod one. Since the other end of the drive shaft is fixed to the drive arm, and the drive arm is fixed on the flipping plate, when the drive arm rotates with the drive shaft, the clamping block rotates inside the fixed frame one, and the flipping plate is fixed to the clamping block by bolts, which can drive the flipping plate to rotate around the clamping block inside the fixed frame one, realizing angle adjustment. When the flipping plate rotates through the fixed frame one, the clamping adjustable component adjusts the angle synchronously with the flipping plate to keep the clamping direction of the steel and the flipping angle matched. Then, by twisting the coarse bolt and the fine bolt, the steel of different shapes can be firmly clamped.

[0010] A further improvement of the present invention is that the adjustable clamping component includes coarse bolts and fine bolts. The coarse bolts are arranged in several groups and are connected to the flip plate in a rectangular, equidistant thread. The fine bolts are arranged in several groups and are connected to the flip plate in a rectangular, equidistant thread.

[0011] Using the above technical solution, after the steel material has passed through the telescopic component to adjust the spacing and the flipping mechanism to adjust the angle, the coarse bolts can be tightened. Due to the wide thread spacing of the coarse bolts, they can be quickly pushed forward and directly pressed against the surface of the steel material. Through the synergistic effect of multiple sets of coarse bolts, the steel material can be initially limited, quickly reducing the gap between the steel material and the flipping plate. Then, by tightening the fine bolts, due to their fine threads, the fine bolts can accurately press against the minor unevenness or gaps on the surface of the steel material. By adjusting the screwing depth of multiple sets of coarse and fine bolts, the fitting and fixing of complex-shaped steel materials can be achieved. Moreover, the angles of the coarse and fine bolts can be adjusted synchronously with the flipping plate, ensuring that the coarse and fine bolts can always press against the steel material at the optimal angle under any condition, thus ensuring the stability of the fixing during the welding process.

[0012] A further improvement of the present invention is that: the telescopic component includes a push plate, an electric push rod two is symmetrically fixedly installed inside the bottom of the clamping platform, the top of the push plate is fixedly installed at the bottom of the sliding plate, and one side of the push plate is fixedly installed with the output end of the electric push rod two.

[0013] Using the above technical solution, after the steel is placed on the clamping table, according to the length requirements of the steel, the electric push rod two is activated. When the output end of the electric push rod two extends or shortens, it can drive the sliding plate to slide laterally along both sides of the clamping table through the push plate, thereby changing the distance between the two sliding plates. This achieves efficient adaptation of the steel length, and the adjustment of the telescopic component provides a foundation for the flipping mechanism and clamping component. By precisely controlling the distance between the sliding plates, the flipping plate is always aligned with the optimal fixing point of the steel, ensuring the effectiveness of subsequent angle adjustment and clamping operations.

[0014] A further improvement of this utility model is that: a clamping block is rotatably installed inside the fixing frame, and the bottom of the flip plate is detachably fixed inside the clamping block by bolts.

[0015] By adopting the above technical solution, the rotating plate can be quickly replaced with the corresponding specifications according to the shape and size characteristics of the steel through the detachable bolt structure. When the rotating plate is worn or deformed due to long-term high temperature of welding and metal spatter, there is no need to replace the entire fixing frame. The rotating plate can be replaced separately by simply removing the bolts, which greatly reduces maintenance costs and downtime. At the same time, the rotating connection between the clamping block and the fixing frame reduces friction between components, reduces mechanical wear, and extends the service life of the core components.

[0016] A further improvement of this utility model is that universal wheels are fixedly installed on both sides of the bottom of the sliding plate away from the clamping table.

[0017] Using the above technical solution, during the initial position adjustment process of the sliding plate driven by the telescopic component to slide along the clamping table, the caster wheel can provide support and auxiliary guidance for the sliding plate, so that the sliding plate can move more smoothly under the drive of the telescopic component. When it is necessary to adjust the position of the sliding plate and the components above, the operator only needs to push the sliding plate and cooperate with the flexible steering of the caster wheel to drive the sliding plate and the flipping mechanism and clamping components above to move as a whole.

[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0019] 1. This utility model provides a limiting mechanism for welding steel structure materials. By setting a flipping mechanism, an electric push rod can extend and retract to drive the drive shaft and drive arm to flip the flipping plate around the clamping block, realizing arbitrary angle adjustment of the flipping plate within the range of 0-90°. This solves the problem of insufficient angle adjustment flexibility in the background technology, where most equipment can only achieve horizontal or small-angle tilt fixation, which cannot meet the needs of complex working conditions such as vertical welding and large bevel welding.

[0020] 2. This utility model provides a limiting mechanism for welding steel structure steel. By setting an adjustable clamping component, the coarse bolt can quickly form a preliminary limit on the steel, and the fine bolt can accurately abut against the slight unevenness or gap on the surface of the steel. Moreover, the angle of both can be adjusted synchronously with the flip plate to achieve the fitting and fixing of steel with complex shapes. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] A limiting mechanism for welding steel in a steel structure includes a clamping platform 1, with sliding plates 2 symmetrically slidably mounted on both sides of the clamping platform 1. Fixing frames 22 are fixedly mounted on the top of the sliding plates 2 near both sides of the clamping platform 1. A flipping plate 24 is rotatably mounted inside the fixing frames 22. The mechanism also includes a flipping mechanism located on top of the sliding plates 2 and used to adjust the angle of the flipping plate 24.

[0028] A telescopic assembly is located at the bottom of the clamping platform 1 and is used to adjust the lateral spacing of the sliding plates 2.

[0029] The flipping mechanism includes an adjustable clamping component and a second fixing frame 3. The second fixing frame 3 is fixedly installed on both sides of the top of the sliding plate 2 away from the clamping table 1. A fixing ring 31 is rotatably installed inside the second fixing frame 3. An electric push rod 32 is fixedly installed at the end of the fixing ring 31 away from the flipping plate 24. The output end of the electric push rod 32 passes through the fixing ring 31 and is fixedly installed with a bushing 33. A drive shaft 34 is rotatably installed inside the bushing 33. A drive arm 35 is fixedly installed on the side of the flipping plate 24 near the electric push rod 32 and is fixedly installed with the drive shaft 34. The adjustable clamping component is located above the clamping table 1 and is used to fix steel of different shapes.

[0030] The adjustable clamping assembly includes coarse bolts 241 and fine bolts 242. Several sets of coarse bolts 241 are provided and are connected to the flip plate 24 in a rectangular, equidistant thread. Several sets of fine bolts 242 are provided and are connected to the flip plate 24 in a rectangular, equidistant thread.

[0031] The telescopic assembly includes a push plate 361. Electric push rods 36 are symmetrically fixedly installed inside the bottom of the clamping platform 1. The top of the push plate 361 is fixedly installed on the bottom of the sliding plate 2, and one side of the push plate 361 is fixedly installed with the output end of the electric push rods 36.

[0032] The clamping block 23 is rotatably mounted inside the fixed frame 22, and the bottom of the flip plate 24 is detachably fixed inside the clamping block 23 by bolts.

[0033] Universal wheels 21 are fixedly installed on both sides of the bottom of the sliding plate 2 away from the clamping table 1.

[0034] Example 1

[0035] The adjustable clamping component includes coarse bolts 241 and fine bolts 242. Several sets of coarse bolts 241 are provided and are connected to the flip plate 24 in a rectangular and equidistant threaded manner. Several sets of fine bolts 242 are provided and are connected to the flip plate 24 in a rectangular and equidistant threaded manner.

[0036] In this embodiment, after the steel material's spacing is adjusted by the telescopic component and its angle is adjusted by the flipping mechanism, the coarse bolts 241 can be tightened. Due to the wide thread pitch of the coarse bolts 241, they can be quickly pushed forward and directly pressed against the steel surface. Through the synergistic effect of multiple sets of coarse bolts 241, the steel material can be initially limited, quickly reducing the gap between the steel material and the flipping plate 24. Then, by tightening the fine bolts 242, due to their fine threads, the fine bolts 242 can accurately press against the minor unevenness or gaps on the steel surface. By adjusting the screwing depth of multiple sets of coarse bolts 241 and fine bolts 242, the steel material with complex shapes can be fitted and fixed. Moreover, the angles of the coarse bolts 241 and fine bolts 242 can be adjusted synchronously with the flipping plate 24, ensuring that the coarse bolts 241 and fine bolts 242 can always press against the steel material at the optimal angle under any condition, ensuring the stability of the fixing during the welding process.

[0037] Example 2

[0038] The flipping mechanism includes an adjustable clamping component and a second fixing frame 3. The second fixing frame 3 is fixedly installed on both sides of the top of the sliding plate 2 away from the clamping table 1. A fixing ring 31 is rotatably installed inside the second fixing frame 3. An electric push rod 32 is fixedly installed at the end of the fixing ring 31 away from the flipping plate 24. The output end of the electric push rod 32 passes through the fixing ring 31 and is fixedly installed with a bushing 33. A drive shaft 34 is rotatably installed inside the bushing 33. A drive arm 35 is fixedly installed on the side of the flipping plate 24 near the electric push rod 32 and is fixedly installed with the drive shaft 34. The adjustable clamping component is set above the clamping table 1 and is used to fix steel of different shapes.

[0039] In this embodiment, when the steel is placed on the clamping table 1, the telescopic assembly can drive the sliding plate 2 to slide along the clamping table 1 according to the length of the steel, so that the flip plate 24 on the top of the sliding plate 2 is aligned with the part of the steel that needs to be fixed, completing the initial position alignment. If the steel needs to be welded at an angle or vertically, the electric push rod 32 on the fixing frame 3 can be activated. The bushing 33 on the output end of the electric push rod 32 drives the drive shaft 34 to rotate. Since the other end of the drive shaft 34 is fixed to the drive arm 35, and the drive arm 35 is fixed on the flip plate 24, the drive... When the arm 35 rotates with the drive shaft 34, the clamping block 23 rotates inside the fixed frame 22, and the flipping plate 24 is fixed to the clamping block 23 by bolts. This allows the flipping plate 24 to rotate around the clamping block 23 inside the fixed frame 22, thus achieving angle adjustment. When the flipping plate 24 rotates through the fixed frame 22, the adjustable clamping component adjusts its angle synchronously with the flipping plate 24 to maintain the clamping direction of the steel and the flipping angle matching. Then, by twisting the coarse bolt 241 and the fine bolt 242, the steel of different shapes can be firmly clamped.

[0040] The working principle of the limiting mechanism for the welding of steel materials in this steel structure will be explained in detail below.

[0041] like Figure 1-4 As shown, the limiting mechanism for welding steel materials in this steel structure achieves precise positioning of the steel materials through the coordinated actions of the telescopic component, the flipping mechanism, and the adjustable clamping component. The specific workflow is as follows:

[0042] After the steel is placed on the clamping platform 1, the telescopic assembly starts working: the electric push rod 36 at the bottom of the clamping platform 1 outputs driving force according to the length of the steel, which drives the sliding plates 2 on both sides to slide laterally along the clamping platform 1 through the push plate 361. The universal wheels 21 at the bottom of the sliding plates 2 provide auxiliary support and reduce friction to ensure smooth sliding. The electric push rod 36 can be driven on one side or simultaneously to flexibly adjust the distance between the sliding plates 2 on both sides, so that the top flip plate 24 is accurately aligned with the part of the steel to be fixed, and the initial positioning is completed.

[0043] If tilting or vertical welding is required, the flipping mechanism starts to operate: the electric push rod 32 on the fixed frame 2 3 extends and retracts, driving the drive shaft 34 to rotate through the bushing 33. The drive shaft 34 transmits torque to the flipping plate 24 through the drive arm 35. The flipping plate 24 flips with the clamping block 23 in the fixed frame 22 as the fulcrum. The fixing ring 31 rotates in the fixed frame 2 3 as the angle of the electric push rod 32 changes, avoiding the electric push rod 32 from being rigidly stressed due to the rotation of the flipping plate 24, ensuring that the direction of the driving force matches the flipping trajectory. Through the precise extension and retraction of the electric push rod 32, the flipping plate 24 can be adjusted to any angle within the range of 0-90°.

[0044] After the angle adjustment is completed, the clamping adjustable components are firmly fixed: several sets of coarse bolts 241 are rectangularly distributed on the flip plate 24, which are quickly pushed in through the wide threads and directly press against the steel surface to form a multi-point initial limit; the fine bolts 242 are finely adjusted using fine threads to accurately fill the tiny gaps on the steel surface. By adjusting the screwing depth of each set of bolts differently, they can be adapted to steel with complex cross sections such as round and irregular shapes. Since the bolts rotate synchronously with the flip plate 24, their pressing direction is always perpendicular to the steel contact surface, ensuring clamping stability at any angle.

[0045] When it is necessary to replace steel of different specifications, the detachable bolt structure of the fixed frame 22 and the flip plate 24 allows for quick replacement of the appropriate flip plate 24; the rotating connection between the clamping block 23 and the fixed frame 22 reduces component wear and extends service life. If it is necessary to adjust the overall position of the equipment, the sliding plate 2 can be pushed to achieve flexible steering through the caster wheel 21, and quickly adapt to different welding station layouts.

[0046] Through the above process, the mechanism balances adjustment efficiency, positioning accuracy, and scenario compatibility, providing a stable and reliable limit guarantee for steel structure welding.

[0047] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
