Description
Technical Field
[0001] This utility model relates to the field of water pipe welding technology, and in particular to a welding fixture for radiator water pipes. Background Technology
[0002] Radiators are an important and basic component of hot water (or steam) heating systems. Hot water is cooled inside the radiator (or steam condenses inside the radiator) to provide heat to the room, achieving the purpose of heating. Water pipes are the conduits for supplying water. Commonly used water pipe materials for radiators include carbon steel pipes, stainless steel pipes, copper pipes, and aluminum pipes. Each of these materials has its unique characteristics and applicable scenarios.
[0003] Radiator water pipes need to be clamped and welded using welding fixtures. However, the specifications of radiator water pipes vary and they may be bent. Conventional welding fixtures cannot easily rotate or adjust the water pipes after fixing them, and bent water pipes are not easy to weld. Therefore, a radiator water pipe welding fixture is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a radiator water pipe welding fixture, which solves the problems mentioned in the background.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a radiator water pipe welding fixture, comprising a device platform and a loading plate. Loading plates are symmetrically arranged on the device platform, and a second rotating rod is rotatably connected to the front of the device platform. An installation groove is provided inside the device platform below a loading plate, and a connecting column is rotatably connected in the installation groove. A worm gear is installed on the connecting column. One end of the second rotating rod extends into the installation groove and is fitted with a worm. The top end of the connecting column extends to the top end of the device platform and is fixedly connected to a loading plate.
[0006] As a further technical solution of this utility model, the worm gear meshes with the worm wheel, and a strip frame is installed on both loading plates. A first rotating rod is rotatably connected to one end of each of the two strip frames, and a bidirectional lead screw is rotatably connected inside each of the two strip frames.
[0007] As a further technical solution of this utility model, one end of each of the two first rotating rods extends into the interior of the strip frame and is fixedly connected to one end of the bidirectional lead screw. A second connecting block is symmetrically arranged on each of the two bidirectional lead screws, and a second connecting strip is installed on the top of each of the two second connecting blocks.
[0008] As a further technical solution of this utility model, the top ends of both strip frames are provided with second sliding grooves that are adapted to the second connecting strips, and the top ends of both second connecting strips extend to the outside of the strip frames and are equipped with arc-shaped clamping rods.
[0009] As a further technical solution of this utility model, a third rotating rod is rotatably connected to one side of the device platform, a threaded rod is rotatably connected inside the device platform, a first connecting block is rotatably connected to the threaded rod, and a first connecting strip is installed at the top of the first connecting block.
[0010] As a further technical solution of this utility model, the device platform is provided with a first sliding groove adapted to the first connecting strip, the top end of the first connecting strip extends to the outside of the top end of the device platform and is fixedly connected to another loading plate, and one end of the third rotating rod extends into the inside of the device platform and is rotatably connected to the threaded rod.
[0011] This utility model provides a welding fixture for radiator water pipes, which has the following advantages compared with the prior art:
[0012] 1. This design provides a radiator water pipe welding fixture. Through the setting of a second rotating rod, worm gear, worm wheel and connecting column, rotating the second rotating rod drives the worm gear to rotate. As the worm gear rotates, it drives the worm wheel to rotate. As the connecting column rotates with the worm wheel, it drives a loading plate to rotate. When the water pipe is clamped on the arc-shaped clamping rod, the angle of the water pipe connection can be adjusted with the rotation of the loading plate, so that the bent water pipe can be welded.
[0013] 2. This design includes a radiator water pipe welding fixture. By using a bidirectional lead screw and a threaded rod, the bidirectional lead screw rotates and drives the arc-shaped clamping rod to move, which can adjust the distance between the arc-shaped clamping rods to clamp water pipes of different diameters. When the threaded rod rotates, it adjusts the distance between the two loading plates to achieve butt welding of water pipes of different lengths. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution for welding fixtures for radiator water pipes, including a device platform 1 and a loading plate 2. The loading plate 2 is symmetrically arranged on the device platform 1, and a second rotating rod 5 is rotatably connected to the front of the device platform 1.
[0021] like Figure 1 and Figure 2 As shown, the device platform 1 has an installation groove located below a loading plate 2. A connecting column 8 is rotatably connected to the installation groove, and a worm gear 9 is installed on the connecting column 8. One end of the second rotating rod 5 extends into the installation groove and is fitted with a worm 7. The top end of the connecting column 8 extends to the top end of the device platform 1 and is fixedly connected to a loading plate 2. The worm 7 meshes with the worm gear 9. Rotating the second rotating rod 5 drives the worm 7 to rotate, which in turn drives the worm gear 9 to rotate. The worm gear 9 drives the connecting column 8 to rotate, which in turn drives the loading plate 2 to rotate, thus adjusting the angle of the loading plate 2 and the welding angle of the water pipe clamped on the loading plate 2.
[0022] like Figure 4 As shown, two loading plates 2 are each equipped with a strip frame 3. One end of each strip frame 3 is rotatably connected to a first rotating rod 4. The inside of each strip frame 3 is rotatably connected to a double-acting screw 13. One end of each first rotating rod 4 extends into the inside of the strip frame 3 and is fixedly connected to one end of the double-acting screw 13. Two second connecting blocks 14 are symmetrically arranged on each of the two double-acting screw 13. A second connecting strip 15 is installed at the top of each of the two second connecting blocks 14. The top of each strip frame 3 is provided with a second sliding groove that matches the second connecting strip 15. The top of each second connecting strip 15 extends out of the strip frame 3 and is equipped with an arc-shaped clamping rod 16. Rotating the first rotating rod 4 causes the double-acting screw 13 to rotate. When the double-acting screw 13 rotates, it causes the second connecting blocks 14 to move. Rotating the second rotating rod 5 in different directions causes the second connecting blocks 14 to move closer to or further away from each other, adjusting the distance between the arc-shaped clamping rods 16, and clamping and fixing water pipes of different diameters.
[0023] like Figure 1 and Figure 3As shown, a third rotating rod 6 is rotatably connected to one side of the device platform 1, and a threaded rod 10 is rotatably connected inside the device platform 1. A first connecting block 11 is rotatably connected to the threaded rod 10, and a first connecting strip 12 is installed at the top of the first connecting block 11. A first sliding groove adapted to the first connecting strip 12 is provided on the device platform 1. The top of the first connecting strip 12 extends to the outside of the top of the device platform 1 and is fixedly connected to another loading plate 2. One end of the third rotating rod 6 extends into the inside of the device platform 1 and is rotatably connected to the threaded rod 10. Rotating the third rotating rod 6 causes the threaded rod 10 to rotate. When the threaded rod 10 rotates, the first connecting block 11 moves to the outside, thereby causing the other loading plate 2 to move and adjusting the distance between the two loading plates 2.
[0024] The working principle of this utility model is as follows: Two water pipes to be welded are placed between arc-shaped clamping rods 16 on two loading plates 2. Rotating the first rotating rod 4 drives the bidirectional lead screw 13 to rotate. When the bidirectional lead screw 13 rotates, it drives the second connecting block 14 to move, causing the arc-shaped clamping rods 16 to move closer together and clamp the water pipes. According to the length of the water pipe, rotating the third rotating rod 6 drives the threaded rod 10 to rotate. When the threaded rod 10 rotates, the first connecting block 11 moves outward, thereby driving the other loading plate 2 to move, adjusting the distance between the two loading plates 2. If a bent water pipe needs to be welded, the bent water pipe is clamped on one loading plate 2. Rotating the second rotating rod 5 drives the worm gear 7 to rotate. When the worm gear 7 rotates, it drives the worm wheel 9 to rotate. The worm wheel 9 drives the connecting column 8 to rotate, and the connecting column 8 drives one loading plate 2 to rotate, adjusting the angle of one loading plate 2. Simultaneously, the angle of the water pipe is adjusted to facilitate welding.
[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
