Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a positioning component for pipe welding. Background Technology

[0002] A pipeline is a tubular device used to transport various fluids or solid materials, widely used in petroleum, chemical, natural gas, water supply and drainage, and many other fields. Because pipelines need to be connected to form complete transport components during use, welding has become a common connection method. This ensures a strong and leak-proof connection, preventing leakage of the transported medium, and provides high strength and stability to withstand internal pressure, external loads, and environmental factors. Pipeline welding positioning components are devices used to precisely fix the position and angle of the pipeline during the welding process. Their function is to ensure the alignment accuracy of the two pipes to be welded, preventing misalignment, displacement, and other defects during welding, thereby improving welding quality and efficiency, and ensuring the safe and reliable operation of the entire pipeline.

[0003] Pipe welding positioning assemblies consist of a clamping part, a positioning part, and a supporting part. The clamping part is the component that directly contacts and fixes the pipe; common types include V-shaped clamps, U-shaped clamps, and clamps. V-shaped clamps are suitable for circular pipes and can automatically center; U-shaped clamps are more adaptable to pipes of different shapes and sizes; clamps are generally used for quick clamping of larger diameter pipes. The positioning part determines the horizontal and vertical position of the pipe by inserting it into pre-drilled holes in the pipe or mating it with specific parts on the pipe surface, ensuring that the axes of the two pipes to be welded coincide and guaranteeing the quality of the weld joint. The number and position of the positioning pins depend on the pipe diameter and welding requirements; generally, multiple positioning pins are placed at both ends of the pipe or symmetrically. The supporting part is the foundation of the entire positioning assembly, bearing the weight of the pipe, clamping mechanism, and positioning mechanism, as well as the stress generated during welding. The base is usually made of cast iron, steel plate, or other materials, possessing sufficient strength and stability.

[0004] In existing technologies, some positioning components for pipe welding cannot guarantee that the pipe will be accurately positioned in the required location due to the influence of pipe processing precision. Therefore, without positioning components, more time is needed for manual adjustment and measurement before welding to ensure that the position and angle of the pipe meet the welding requirements. To address this issue, a positioning component for pipe welding is proposed. Utility Model Content

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.

[0032] Reference Figure 2 and Figure 3 This utility model provides an embodiment of a positioning component for pipe welding, including a handle 1, which is a part held by the operator for easy handling. Two outer shells 2 are fixedly connected to the rear side of the handle 1. The outer shells 2 protect the internal welding structure from damage. A protective cover 3 is fixedly connected to the top of one of the outer shells 2, protecting the internal positioning component from damage. An electric push plate 4 is fixedly connected to the inner wall of the protective cover 3, serving as the driving source for the positioning component and applying a pushing force to a push rod 5. The driving end of the electric push plate 4 is fixedly connected to the push rod 5, which receives the force from the electric push plate 4 and transmits it to a moving plate 6. A moving plate 6 is fixedly connected to the rear side of the push rod 5, receiving the force from the push rod 5 and moving within the protective cover 3. This causes the rotating plates 7 on both sides to rotate. The rotating plates 7 are rotatably connected to both sides of the moving plate 6. The rotating plates 7 rotate under the action of the moving plate 6, thereby causing the rotating plate 8 to rotate. The rotating plate 8 is rotatably connected to the other side of the rotating plates 7. The rotating plate 8 rotates slightly to transmit force. The grooved plate 9 is fixedly connected to the rear side of the rotating plate 8. The grooved plate 9 receives the force transmitted by the rotating plate 8 and rotates accordingly, thereby moving the horizontal plate. The horizontal plate is rotatably connected to the rear side of the grooved plate 9. The horizontal plate moves under the rotation of the grooved plate 9, thereby causing the fan ring 10 to exert force on the pipe. The fan ring 10 is fixedly connected to the rear side of the horizontal plate. The fan ring 10 directly contacts the pipe and is also an important positioning component. Fixing components for fixing pipe fittings are fixedly connected to the left side of both outer shells 2.

[0033] Reference Figure 1 and Figure 4The fixing assembly includes two fixing members 14, which drive the semicircular ring 15 and the semicircular plate 16 to rotate. The right sides of the two fixing members 14 are fixedly connected to the left sides of the two outer shells 2. The semicircular ring 15 is fixedly connected to the right side of the rear side of the two fixing members 14. The semicircular ring 15 moves with the fixing member 14 to lock the pipe. The semicircular plate 16 is fixedly connected to the adjacent side of the two semicircular rings 15. The semicircular plate 16 directly fixes the pipe under the action of the fixing member 14. The bottom of the outer shell 2 is fixedly connected to the connecting plate 19, which connects the outer shell 2 and the rotating plate 17. The bottom of the connecting plate 19 is fixedly connected to the rotating plate 17. The rotating plate 17 receives the command transmitted by the handle, thereby causing the rotating plate 17 to drive the rotating ring 18 to rotate.

[0034] Reference Figures 1 to 3 The bottom of the movable plate 6 is slidably connected to the inner wall of the protective cover 3. The movable plate 6 moves under the action of the push rod 5, thereby causing the rotating plate to rotate. The bottom of the rotating plate 8 is rotatably connected to the inner wall of the protective cover 3. The rotating plate 8 receives the force of the rotating plate 7 and thus rotates. A sliding groove is provided on the rear side of the protective cover 3. The sliding groove allows the fan ring 10 to move and rotate. The outer side of the fan ring 10 is slidably connected to the inner wall of the rear side of the protective cover 3. The fan ring 10 rotates and moves under the action of the groove plate 9. Two fixing blocks 11 are fixedly connected to the top of the semi-circular ring 15. The fixing blocks 11 allow the movable rod 12 to move inside, thereby buffering the pipe. The inner walls of the two fixing blocks 11 are connected to the movable rod 12. The movable rod 12 moves under the action of the fan ring 13, thereby moving. A spring is provided on the outside. The front side of the movable rod 12 is fixedly connected to the fan ring 13. 13 is in direct contact with the pipe. Under the action of the spring, it is buffered and fixed. The front side of the operating plate 17 is fixedly connected to the rear side of the handle 1. The operating plate 17 directly receives the command transmitted by the handle. The rear side of the operating plate 17 has a rotating groove to allow the rotating ring 18 to rotate. The rotating ring 18 is rotatably connected to the rear side of the operating plate 17. The rotating ring 18 is directly connected to the pipe and is fixed during rotation. The outer side of the rotating ring 18 contacts the semicircular plate 16 under the drive of the operating plate 17. The rotating ring 18 rotates inside, thereby further fixing it. The front side of the semicircular ring 15 contacts the rear side of the outer shell 2 under the fixation of the fixing member 14. The semicircular ring 15 moves with the fixing member 14, thereby fixing it to the outer shell 2. The front side of the connecting plate 19 is fixedly connected to the rear side of the handle 1. The connecting plate 19 is fixed inside and is fixed under the action of the handle.

[0035] Working principle: When positioning the pipeline, the electric push plate 4 is activated, which pushes the push rod 5 to move, thereby moving the push plate and rotating the first rotating plate 7. The rotation of the first rotating plate 7 causes the second rotating plate 8 to rotate, which in turn moves the grooved plate 9, thereby moving the first fan ring 10 to position the pipeline. This causes the second fan ring 13 to move, and the spring on the moving rod 12 compresses it. Under the action of the spring, the second fan ring 13 returns to its original position. Thus, under the action of the first fan ring 10 and the second fan ring 13, the pipeline is positioned and fixed. In addition, this ensures the accurate and stable position of the pipeline during welding, which is conducive to improving the welding quality. This facilitates construction operations and improves the overall efficiency of pipeline welding.

[0036] Under the action of the fixing component 14, the semicircular ring 15 and the semicircular plate 16 are merged, and the pipe is placed inside. Then the rotating plate 17 is started. The rotating plate 17 drives the rotating ring 18 to rotate. Under the rotation of the rotating ring, the welding joint inside the rotating ring 18 is in the optimal position, so as to weld it and realize the fixed welding of the pipe. In addition, it can accurately fix the position of the pipe and ensure that the pipe does not shift during the welding process, thereby improving the accuracy and quality of the weld joint and reducing the probability of welding defects.

[0037] 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.
