Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a rotary welding device for the oil guide pipe plug of a plate radiator for transformers. Background Technology

[0002] In the manufacturing process of plate radiators for transformers, the welding quality of the oil guide pipe and the plug plate directly affects the sealing performance and service life of the radiator.

[0003] Existing welding methods have many drawbacks when welding oil guide pipes and plugs. Manual welding usually relies on the welder's experience and skill level. During the welding process, hand tremors and inaccurate control of welding angle and speed can easily lead to defects such as porosity, slag inclusion, and incomplete penetration in the weld, resulting in insufficient weld joint strength. This makes it difficult to withstand the pressure during transformer oil circulation and poses a risk of oil leakage. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the current welding method has defects in connecting the oil pipe and the plug plate. It relies on the experience and skills of the welder. The hand tremors and inaccurate control of angle and speed during welding can easily produce problems such as porosity, slag inclusion, and incomplete penetration, resulting in insufficient strength of the welded joint. It may not be able to withstand the transformer oil circulation pressure and there is a risk of oil leakage. To this end, we propose a rotary welding device for the plug plate of the oil pipe of the plate radiator for transformers.

[0005] To achieve the above objectives, this application adopts the following technical solution: a rotary welding device for the oil guide pipe plug of a transformer plate radiator, comprising an operating table, a welding machine mounted on the top of the operating table, a rotary motor mounted on the top of the operating table, a placement plate fixedly connected to the output end of the rotary motor, two moving slots opened on the top of the placement plate, a moving block slidably connected inside the moving slots, a clamping plate fixedly connected to the top of the moving block, a connecting block fixedly connected to one side of the clamping plate, a slot opened on one side of the connecting block, an adjusting plate slidably connected inside the slot, a plug-in rod fixedly connected to the bottom of the adjusting plate, a through slot opened at the bottom of the inner cavity of the slot, and two plug-in slots opened on the top of the placement plate.

[0006] Preferably, the surface of the plug rod is slidably connected to the inside of the plug groove, and the outer diameter of the plug rod is adapted to the inner diameter of the plug groove.

[0007] Preferably, sliding grooves are provided on both sides of the inner cavity of the slot, and sliders are fixedly connected to both sides of the adjusting plate.

[0008] Preferably, a reset spring is fixedly connected to the bottom of the adjusting plate, and the bottom of the reset spring is fixedly connected to the bottom of the groove cavity.

[0009] Preferably, limit grooves are provided at both ends of the inner cavity of the moving groove, and limit blocks are fixedly connected to both ends of the moving block.

[0010] Preferably, a thrust spring is fixedly connected to one side of the movable block, and one side of the thrust spring is fixedly connected to one side of the inner cavity of the movable groove.

[0011] Preferably, the inner wall of the clamp is fixedly connected with an anti-slip pad.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operator places the oil guide pipe on top of the placement plate, then moves the connecting block to position the oil guide pipe using the clamping plate. Next, the adjusting plate is moved downwards to insert the insertion rod into the insertion slot, fixing the clamping plate's position. Then, the rotating motor is started, causing the placement plate to rotate. This rotation of the placement plate causes the oil guide pipe on top to rotate as well.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figures 1-5 As shown, this utility model provides a technical solution: a rotary welding device for the oil pipe plug of a transformer plate radiator, including an operating table 1, a welding machine 2 mounted on the top of the operating table 1, a rotary motor 3 mounted on the top of the operating table 1, a placement plate 4 fixedly connected to the output end of the rotary motor 3, two moving slots 5 opened on the top of the placement plate 4, moving blocks 6 slidably connected inside the moving slots 5, a clamping plate 7 fixedly connected to the top of the moving blocks 6, a connecting block 8 fixedly connected to one side of the clamping plate 7, a slot 9 opened on one side of the connecting block 8, an adjusting plate 10 slidably connected inside the slot 9, a plug rod 11 fixedly connected to the bottom of the adjusting plate 10, and a through slot 12 opened at the bottom of the inner cavity of the slot 9. Two insertion slots 20 are provided at the top. The operator places the oil guide tube on the top of the placement plate 4, and then moves the connecting block 8 to position the oil guide tube by the clamping plate 7. Then, by moving the adjusting plate 10 downward, the adjusting plate 10 moves the insertion rod 11 into the insertion slot 20 to fix the position of the clamping plate 7. Then, the rotating motor 3 is started to rotate the placement plate 4. The rotation of the placement plate 4 causes the oil guide tube on its top to rotate. At the same time, the welding machine 2 is started to weld the plug plate of the rotating oil guide tube. Through the rotation of the rotating motor 3, the welding machine 2 can evenly weld the plug plate of the oil guide tube, improving welding efficiency and quality.

[0023] Reference Figure 3 and Figure 5 As shown in this embodiment: the surface of the plug rod 11 is slidably connected to the inside of the plug groove 20, and the outer diameter of the plug rod 11 is adapted to the inner diameter of the plug groove 20. Since the plug rod 11 is slidably connected to the plug groove 20 and the size is adapted, it is ensured that the plug rod 11 can be stably inserted into the plug groove 20, thereby achieving a firm fixation of the clamping plate 7. This design not only enhances the stability of the device, but also ensures that the oil guide pipe plug plate will not affect the welding quality due to shaking during the welding process.

[0024] Reference Figure 5As shown in this embodiment: both sides of the inner cavity of the slot 9 are provided with sliding grooves 13, and both sides of the adjusting plate 10 are fixedly connected with sliders 14. The surface of the sliders 14 is slidably connected to the inside of the sliding grooves 13. Since the sliders 14 are slidably connected to the sliding grooves 13, the adjusting plate 10 can remain stable when moving, avoiding the situation where the adjusting plate 10 deviates or shakes during the movement, thereby ensuring that the plug rod 11 can be accurately inserted into the plug slot 20, further improving the stability and reliability of the device.

[0025] Reference Figure 5 As shown in this embodiment: a return spring 15 is fixedly connected to the bottom of the adjusting plate 10, and the bottom of the return spring 15 is fixedly connected to the bottom of the inner cavity of the slot 9. Since the bottom of the adjusting plate 10 is fixedly connected to the return spring 15, and the bottom of the return spring 15 is fixedly connected to the bottom of the inner cavity of the slot 9, this design allows the adjusting plate 10 to quickly return to its initial position after being subjected to external force. The introduction of the return spring 15 not only enhances the flexibility of the adjusting plate 10, but also ensures that the adjusting plate 10 can still maintain a good reset effect after multiple uses.

[0026] Reference Figure 3 and Figure 4 As shown in this embodiment: both ends of the inner cavity of the moving groove 5 are provided with limiting grooves 16, and both ends of the moving block 6 are fixedly connected with limiting blocks 17. The surface of the limiting block 17 is slidably connected to the inside of the limiting groove 16. This design allows the moving block 6 to be restricted by the limiting groove 16 during the movement, thereby preventing the moving block 6 from detaching from the moving groove 5 during the movement, and further improving the stability and safety of the device.

[0027] Reference Figure 6 As shown in this embodiment: a thrust spring 19 is fixedly connected to one side of the moving block 6, and one side of the thrust spring 19 is fixedly connected to one side of the inner cavity of the moving groove 5. When the clamping plate 7 is released from fixation, the thrust spring 19 will push the moving block 6 to move outward in the moving groove 5 through its own elastic force, thereby causing the clamping plate 7 to automatically separate, which makes it easy for the staff to quickly take out the welded oil guide pipe. This design not only simplifies the operation process, but also improves work efficiency.

[0028] Reference Figure 6 As shown in this embodiment: the inner wall of the clamping plate 7 is fixedly connected with an anti-slip pad 18. The anti-slip pad 18 increases the friction between the clamping plate 7 and the oil guide pipe, effectively preventing the oil guide pipe from slipping or loosening during the welding process, and ensuring the stability of the welding process and the accuracy of the welding position of the oil guide pipe.

[0029] Working principle: The operator places the oil guide tube on top of the placement plate 4, then moves the connecting block 8 to position the oil guide tube using the clamping plate 7. Next, the adjusting plate 10 is moved downwards, causing the insertion rod 11 to insert into the insertion slot 20, fixing the position of the clamping plate 7. Then, the rotating motor 3 is started, causing the placement plate 4 to rotate. The rotation of the placement plate 4 causes the oil guide tube on top to rotate as well. Simultaneously, the welding machine 2 is started, welding the plug on the rotating oil guide tube. The rotation of the rotating motor 3 allows the welding machine 2 to weld the plug on the oil guide tube. Uniform welding improves welding efficiency and quality. Because the insertion rod 11 is slidably connected to the insertion slot 20 and its dimensions are compatible, it ensures that the insertion rod 11 can be firmly inserted into the insertion slot 20, thus achieving a secure fixation of the clamping plate 7. This design not only enhances the stability of the device but also ensures that the oil guide pipe plug plate will not affect the welding quality due to shaking during the welding process. The surface of the slider 14 is slidably connected to the inside of the slide groove 13. Because the slider 14 and the slide groove 13 are slidably connected, the adjusting plate 10 can remain stable during movement, avoiding any offset or shaking during movement, thereby ensuring that the insertion rod 11 can... The device is accurately inserted into the insertion slot 20, further improving its stability and reliability. Since a return spring 15 is fixedly connected to the bottom of the adjusting plate 10, and the bottom of the return spring 15 is fixedly connected to the bottom of the inner cavity of the slot 9, this design allows the adjusting plate 10 to quickly return to its initial position after being subjected to external force. The introduction of the return spring 15 not only enhances the flexibility of the adjusting plate 10 but also ensures that the adjusting plate 10 maintains a good reset effect after multiple uses. The surface of the limiting block 17 is slidably connected to the inside of the limiting groove 16. This design allows the moving block 6 to be restricted by the limiting groove 16 during movement, thereby avoiding... This design eliminates the possibility of the moving block 6 detaching from the moving groove 5 during movement, further improving the stability and safety of the device. When the clamping plate 7 is released from its fixed position, the thrust spring 19 will push the moving block 6 outward within the moving groove 5 through its own elastic force, thereby causing the clamping plate 7 to automatically separate. This allows the staff to quickly remove the welded oil guide pipe. This design not only simplifies the operation process but also improves work efficiency. The anti-slip pad 18 increases the friction between the clamping plate 7 and the oil guide pipe, effectively preventing the oil guide pipe from slipping or loosening during welding, ensuring the stability of the welding process and the accuracy of the oil guide pipe welding position.
