Description

Technical Field

[0001] This utility model relates to the field of welding alignment technology, and in particular to a steel welding alignment mechanism. Background Technology

[0002] The steel welding alignment mechanism is one of the core auxiliary equipment to ensure welding quality. It is usually composed of a load-bearing base, support components and clamping components. Its main function is to accurately position the multiple steel sections (or steel components) to be welded before the steel welding operation, to ensure that the parameters such as weld gap, misalignment, and coaxiality of the steel to be welded meet the process requirements, and to ensure the mechanical properties and structural stability of the steel structure after welding.

[0003] In actual production, existing steel welding alignment mechanisms require two locking nuts located above and below the support platform for fixation. This necessitates operations on both sides of the support platform when installing or adjusting the support components. For example, the screw of the support component must be inserted into the mounting hole from below the support platform, and then nuts must be fitted and tightened from both above and below. When adjusting the position of the support component, the upper and lower fixing nuts must be loosened first, then the support component must be pushed from above to the target position, and finally the upper and lower nuts must be tightened again. This operation method not only requires operators to reserve sufficient operating space under the support platform, increasing the equipment's footprint, but also requires multiple people to cooperate or frequent switching of operating positions, resulting in a lengthy time-consuming process for installing, disassembling, or adjusting the support components. Utility Model Content In view of the above-mentioned prior art, the present invention provides a steel welding alignment mechanism. The first screw can pass from the top to the bottom of the multi-hole platform, and can be locked or loosened by a nut on the top of the multi-hole platform. The installation, disassembly or adjustment operations can all be completed on the top of the multi-hole platform, making the operation more convenient.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows: A steel welding alignment mechanism includes a multi-hole platform, a support assembly, and a clamping assembly. The multi-hole platform includes an upper plate and a lower plate, which are provided with an array of square holes aligned in the vertical direction. The support assembly is provided with a clamping assembly for clamping steel. The support assembly includes a first screw, a nut, and a square boss. The square boss is provided at the bottom of the first screw. The inner side of the square hole is tangent to the outer surface of the first screw. The bottom of the lower plate is provided with a square slot, which coincides with the center of the square hole and the apex is offset.

[0005] Furthermore, the bottom of the nut is provided with a circular boss, and the edge of the circular boss is chamfered.

[0006] Furthermore, the clamping assembly includes an upper clamping rod, a lower clamping rod, and a second screw. The upper clamping rod is slidably connected to the lower clamping rod, the lower clamping rod is fixedly connected to the first screw, the lower clamping rod is threadedly connected to the second screw, and the upper end of the second screw is rotatably connected to the upper clamping rod.

[0007] Furthermore, the lower clamping rod is provided with a threaded hole, and the second screw cooperates with the threaded hole.

[0008] Furthermore, the thread of the second screw is a trapezoidal thread.

[0009] Furthermore, the lower clamping rod is provided with a vertically arranged guide rail, and the upper clamping rod is provided with a vertically arranged guide rod, the guide rod being slidably connected to the guide rail.

[0010] Furthermore, the top of the second screw is provided with a limiting post, the limiting post has a through hole, and an operating handle passes through the through hole.

[0011] Furthermore, both the front and rear ends of the operating handle are provided with plugs, and the diameter of the plugs is larger than the diameter of the through hole.

[0012] Furthermore, the porous platform also includes support legs, which are disposed around the lower plate.

[0013] Furthermore, the porous platform also includes a side plate, the upper end of which is connected to the upper plate, and the lower end of which is connected to the lower plate.

[0014] The beneficial effects of this utility model are as follows: The multi-hole platform of this utility model has multiple square holes arranged in an array, allowing the support assembly to be installed in appropriate square holes, thus improving the adaptability of the alignment mechanism. When installing the support assembly, the first screw is inserted from top to bottom and then locked with a nut; the entire locking operation is completed above the multi-hole platform, making operation more convenient. Preferably, after the nut is loosened a certain distance, the directional protrusion at the bottom of the first screw can be engaged in the directional slot, and then the nut is rotated to lock it, enabling quick installation of the support assembly. In addition, the outer surface of the first screw is tangent to the inner side of the directional hole, and after the first screw is installed, its circumference is restricted by the inner side of the square hole, resulting in strong stability. The first screw of the support assembly is fixed by the square holes in the upper and lower plates, and a certain distance exists between the upper and lower plates, improving the stability of the first screw.

[0018] Example 1 Please refer to the attached document. Figures 1-6This application provides a steel welding alignment mechanism, including a multi-hole platform 1, a support assembly 2, and a clamping assembly 3. The multi-hole platform 1 includes an upper plate 4 and a lower plate 5, both of which have an array of square holes 6 aligned vertically. The support assembly 2 has a clamping assembly 3 for clamping steel. The support assembly 2 includes a first screw 7, a nut 8, and a square boss 9. The square boss 9 is located at the bottom of the first screw 7. The inner side of the square hole 6 is tangent to the outer surface of the first screw 7. The bottom of the lower plate 5 has a square slot 10, which coincides with the center of the square hole 6 but has its vertices offset. The multi-hole platform 1 includes an upper plate 4 and a lower plate 5, both of which have square holes 6. Preferably, the directional holes are square holes 6, and the inner side of the square hole 6 is tangent to the outer surface of the first screw 7. A square boss 9 is provided at the bottom of the first screw 7, which can pass through the square hole 6. After passing through the square hole 6 of the lower plate 5, the first screw 7 is rotated, causing the square boss 9 to be misaligned with the square hole 6. The square boss 9 is used to lock the first screw 7, preventing it from being pulled upwards. Preferably, a square groove 10 is provided at the bottom of the square hole 6 of the lower plate. After the first screw 7 is rotated 45°, the square boss is inserted into the square groove. This design improves the stability of the support assembly 2. After the square boss 9 at the bottom of the first screw 7 is locked, the first screw 7 is locked by rotating the nut 8. During this process, the nut 8 limits the first screw 7 from above, and the square boss 9 limits the first screw 7 from below, thereby fixing the support assembly 2 on the multi-hole platform 1. Finally, the clamping assembly 3 on the support assembly 2 is used to clamp and fix the steel, aligning the weld seams of the steel and completing the welding alignment. The multi-hole platform 1 of this utility model has multiple square holes 6 arranged in an array, which can be used to install the support component 2, improving the adaptability of the alignment mechanism. When installing the support component 2, the first screw 7 is inserted from top to bottom and then locked with a nut 8. The entire locking operation is completed above the multi-hole platform 1, making the operation more convenient. Preferably, after the nut 8 is loosened a certain distance, the directional protrusion at the bottom of the first screw 7 can be engaged in the directional slot, and then the nut 8 can be rotated to lock it, allowing for quick installation of the support component 2. In addition, the outer surface of the first screw 7 is tangent to the inner side of the directional hole, and after the first screw 7 is installed, its circumference is restricted by the inner side of the square hole 6, resulting in strong stability. The first screw 7 of the support component 2 is fixed by the square holes 6 of the upper plate 4 and the lower plate 5. There is a certain distance between the upper plate 4 and the lower plate 5, which improves the stability of the first screw 7. Preferably, the distance between the upper plate 4 and the lower plate 5 is 10~20cm.

[0019] Specifically, the bottom of the nut 8 is provided with a circular boss 11, and the edge of the circular boss 11 is chamfered. By using the circular boss 11 to contact the upper surface of the upper plate 4, the edge of the nut 8 is prevented from scratching the surface of the upper plate 4, and the force on the circular boss 11 on the upper plate 4 is also more even.

[0020] Specifically, the clamping assembly 3 includes an upper clamping rod 12, a lower clamping rod 13, and a second screw 14. The upper clamping rod 12 is slidably connected to the lower clamping rod 13, the lower clamping rod 13 is fixedly connected to the first screw 7, and the lower clamping rod 13 is threadedly connected to the second screw 14. The upper end of the second screw 14 is rotatably connected to the upper clamping rod 12. The upper clamping rod 12 and the lower clamping rod 13 can slide relative to each other. When the upper clamping rod slides upward, the clamping assembly 3 can be opened, thereby placing the steel between the upper clamping rod 12 and the lower clamping rod 13. By rotating the second screw 14, it is screwed into the lower clamping rod 13, causing the upper clamping rod 12 to move downward and clamp the steel. The clamping assembly 3 can stably clamp the steel and adapt to different steel sizes.

[0021] Specifically, the lower clamping rod 13 is provided with a threaded hole 15, and the second screw 14 cooperates with the threaded hole 15. By utilizing the cooperation between the threaded hole 15 and the second screw 14, rotating the second screw 14 can screw it into the threaded hole 15, thereby driving the upper clamping plate to clamp the steel.

[0022] Furthermore, the thread of the second screw 14 is a trapezoidal thread. The outer surface of the second screw 14 is tangent to the square hole 6. The trapezoidal thread has good wear resistance, ensuring the stability of the second screw 14 and reducing its shaking.

[0023] Specifically, the lower clamping rod 13 is provided with a vertically arranged guide rail 16, and the upper clamping rod 12 is provided with a vertically arranged guide rod 17, the guide rod 17 being slidably connected to the guide rail 16. The cooperation between the guide rod 17 and the guide rail 16 ensures that the upper clamping rod 12 slides stably up and down relative to the lower clamping rod 13, thus improving the clamping stability of the clamping assembly 3.

[0024] Example 2 Please refer to the attached document. Figures 1-6 The difference between this embodiment and Embodiment 1 is that the top of the second screw 14 is provided with a limiting post 18, and the limiting post 18 has a through hole 19 through which an operating handle 20 passes. After the second screw 14 is tightened, the limiting post 18 fits against the top of the upper clamping rod 12, thereby causing the upper clamping rod 12 to press the steel. The operating handle 20 passes through the through hole 19, and the second screw 14 can be rotated by operating the operating handle 20. The steel can be easily clamped and released without the need for external tools, improving the convenience of use.

[0025] Specifically, both the beginning and end of the operating handle 20 are provided with plugs 21, the diameter of which is larger than the diameter of the through hole 19. The plugs 21 prevent the operating handle 20 from disengaging from the through hole 19.

[0026] Specifically, the porous platform 1 further includes support legs 22, which are disposed around the perimeter of the lower plate 5. The support legs 22 are used to support the porous platform 1.

[0027] Specifically, the porous platform 1 further includes side plates 23, the upper end of which is connected to the upper plate 4, and the lower end of which is connected to the lower plate 5. The side plates 23 connect the upper plate 4 and the lower plate 5 of the porous platform 1, improving their stability. Optionally, there may be two or more side plates 23. When there are two side plates 23, the sides are located on the sides of the porous platform 1. When there are two or more side plates 23, the remaining sides are located in the middle of the porous platform 1.

[0028] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
