Description

Technical Field

[0001] This invention relates to the field of transformer manufacturing technology, and in particular to a transformer core centering installation structure with integrated positioning and adjustment functions. Background Technology

[0002] The transformer core is the core of the electromagnetic induction magnetic circuit. It relies on high permeability materials such as silicon steel sheets to build a low magnetic reluctance transmission channel, which can ensure that the magnetic field generated by the alternating current of the primary coil is efficiently conducted to the secondary coil. While realizing the transformation and transmission of electrical energy, it minimizes the energy loss caused by magnetic field leakage and is a key component for transformers to achieve efficient electrical energy conversion.

[0003] The installation quality of the transformer core directly determines the magnetic circuit performance, with precise core alignment being the core requirement. If the core is offset or tilted during installation, gaps can easily form between core components. These gaps not only significantly increase magnetic resistance and exacerbate energy loss, but also cause problems such as localized overheating of the core and increased equipment vibration, seriously threatening the long-term safety and stability of the transformer.

[0004] However, in the current state of the industry, transformer core installation generally lacks an effective adjustable alignment mechanism. Specifically, this manifests in the following ways: 1) Traditional installation methods rely on manual measurement and judgment of whether the core is centered using measuring tools. The measurement accuracy is easily affected by human error, making it difficult to guarantee the accuracy of alignment; 2) If a core offset or gap is detected, the installed core components must be completely dismantled and reassembled. Core alignment cannot be achieved through local adjustments, which not only consumes a lot of manpower and time but also seriously slows down the overall transformer installation progress, significantly restricting project efficiency.

[0005] To address the problems of low alignment accuracy and poor installation efficiency caused by the lack of adjustable alignment capability in existing core installations, there is an urgent need to design a transformer core-related structure with adjustable alignment function to overcome the limitations of traditional installation technology. Summary of the Invention

[0006] The purpose of this invention is to provide a transformer core centering installation structure with integrated positioning and adjustment functions, which aims to solve the problems of existing transformer cores lacking an adjustable centering structure, relying on manual operation for centering accuracy during installation, resulting in large errors, and requiring overall disassembly and modification after offset, which affects magnetic circuit performance and operational safety, and significantly reduces installation efficiency.

[0007] This invention relates to a transformer core centering installation structure with integrated positioning and adjustment functions, including a base, mounting components, positioning components, and buffer components. Four mounting plates are symmetrically mounted in a rectangle on the base, and support plates are symmetrically fixed to the top of the base. A mounting base plate for supporting the mounting components is placed horizontally above the support plates. The mounting components are assembled onto the mounting base plate and have an internal assembly structure adapted to the transformer core for rapid core assembly. The positioning components are mounted on the four mounting plates and, through the combined action of mechanical transmission and position detection, are used to adjust and position the transformer core. The buffer components are assembled on the base and mounting plates to provide elastic protection during core installation.

[0008] As a further improvement to the technical solution disclosed in this invention, the positioning component includes a motor fixed to the outside of one of the mounting plates, a first lead screw fixed to the output end of the motor via a coupling, and a first moving block symmetrically threaded to the outside of the first lead screw; a first limiting rod is fixed between the two mounting plates, and the first moving block slides in cooperation with the first limiting rod.

[0009] As a further improvement to the technical solution disclosed in this invention, an L-shaped connecting frame is fixedly connected to the top of each of the two first moving blocks, and a positioning plate is fixedly connected to the top of each of the two L-shaped connecting frames; a vertical rod is fixedly connected to the top of each of the two positioning plates, and a positioning sensor is installed at the bottom of each of them.

[0010] As a further improvement to the technical solution disclosed in this invention, a bevel gear is fixedly connected to the outside of the first lead screw, and a helical gear is symmetrically meshed with the outside of the bevel gear. A second lead screw is fixedly connected inside each of the two helical gears. The ends of the two second lead screws away from the helical gears are respectively rotatably connected to two other mounting plates.

[0011] As a further improvement to the technical solution disclosed in this invention, the two second lead screws are threadedly connected to the outside of the second moving blocks, and the top of the two second moving blocks are fixedly connected to the second positioning plates through the L-shaped connecting brackets; the positioning plates and the second positioning plates are fixedly connected to the side of each other, and pressure sensors are installed on the soft pads.

[0012] As a further improvement to the technical solution disclosed in this invention, a second limiting rod is fixedly connected between the two mounting plates, and the second limiting rod is slidably engaged with the second moving block.

[0013] As a further improvement to the technical solution disclosed in this invention, the buffer component includes an air pump fixedly attached to the base. The input end of the air pump is fixedly attached to an input head with a dust cover, and the output end is connected in two ways: one way is fixedly attached to a ring pipe installed on the base, and the other way is connected to an exhaust pipe with a control valve facing the mounting component.

[0014] As a further improvement to the technical solution disclosed in this invention, flexible hoses are symmetrically fixed to the outside of the ring pipe, and the ends of multiple flexible hoses away from the ring pipe all pass through the vertical rod and are fixed to a buffer plate; a buffer air cushion is fixed to the outside of the buffer plate, and the buffer air cushion is connected to the flexible hose.

[0015] As a further improvement to the technical solution disclosed in this invention, the mounting component includes a mounting groove formed in the mounting base plate, in which a first iron core is engaged; a coil is sleeved on the outside of the first iron core, and a protrusion is provided on the top.

[0016] As a further improvement to the technical solution disclosed in this invention, a second core is snapped onto the top of the first core, and a groove adapted to the protrusion is formed inside the second core.

[0017] In practical applications, the transformer core centering installation structure with integrated positioning and adjustment function disclosed in this invention can achieve at least the following beneficial technical effects, specifically: 1) By configuring the positioning component, the first lead screw is driven by the motor to rotate, which drives the two first moving blocks to slide along the first limit rod. The positioning plate is moved synchronously through the L-shaped connecting frame. At the same time, the bevel gear and helical gear on the first lead screw mesh, which drives the second lead screw to rotate, so that the second moving block drives the second positioning plate to move synchronously. With the help of the positioning sensor, the first iron core is accurately positioned above the mounting slot, ensuring that it is centered and embedded in the mounting slot, thus achieving accurate installation in one go and greatly improving the installation efficiency. 2) By incorporating a buffer component, compressed air generated by the air pump is delivered to the buffer air cushion on the outside of the buffer plate via a ring pipe and hose, causing the air cushion to expand and form an elastic protective layer. During the installation of the first iron core, the air cushion can absorb the impact force of the iron core falling or moving, preventing the first iron core and coil from being scratched due to rigid contact, effectively protecting the iron core and coil; 3) By configuring the mounting components, the mounting slot of the mounting base plate provides a pre-positioning foundation for the first iron core. The protrusion on the top of the first iron core is precisely matched with the groove inside the second iron core, which can quickly complete the snap-fit ​​assembly of the two. At the same time, the coil can be directly sleeved on the outside of the first iron core, realizing the modular and rapid assembly of the transformer iron core and further improving the installation efficiency.

Detailed Implementation

[0029] The technical solution of the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. Figure 1This diagram illustrates a perspective view of the transformer core centering installation structure with integrated positioning and adjustment functions disclosed in this invention. It shows that the structure includes a base 1, mounting plates 2 symmetrically mounted on the base 1, support plates 16 symmetrically mounted on the base 1, and a mounting base plate 6 placed above the support plates 16. The base plate 6 is made of cast iron, which has excellent casting and vibration damping properties, effectively absorbing vibrations during equipment operation and improving the stability of the entire assembly structure. Furthermore, cast iron has high hardness and good wear resistance, allowing it to withstand the weight of the mounting components 5 for extended periods without easily deforming. The structure also includes: mounting components 5 mounted on the mounting base plate 6 for assembling the transformer core; positioning components 3 mounted on the mounting plate 2 for positioning the transformer core; and buffer components 4 mounted on the base 1 and mounting plate 2 for buffering and protecting the transformer core.

[0030] like Figure 3 , Figure 4 As shown, the positioning component 3 includes a motor 14 mounted on the outside of one of the mounting plates 2. The motor 14 is a high-performance asynchronous motor with a high-strength aluminum alloy shell, which has good heat dissipation performance and corrosion resistance. It can withstand certain vibrations and impacts during long-term operation to ensure stable power output. The internal windings of motor 14 use copper wire, which has excellent conductivity, reduces power loss, and improves the efficiency of motor 14. The output end of motor 14 is fixedly connected to a first lead screw 15 via a coupling. The lead screw 15 is made of high-quality carbon structural steel No. 45, which has undergone heat treatment and precision grinding. It has low surface roughness, high strength and wear resistance, and can maintain precise thread accuracy during repeated transmission, avoiding positioning errors caused by lead screw wear. The first lead screw 15 is externally symmetrically threaded to a first shift block 17. A first limit rod 18 is fixedly connected between the two mounting plates 2. The first shift block 17 is slidably connected to the first limit rod 18. The second lead screw 25 and the second shift block 26 are also symmetrically matched. This design allows the positioning plate 20 and the second positioning plate 27 to move towards or away from the iron core synchronously, ensuring that the iron core is subjected to uniform force in the horizontal direction, avoiding iron core displacement due to unilateral force, and improving the accuracy and stability of positioning.

[0031] In addition, it should be noted that, such as Figure 7As shown, the tops of the two first moving blocks 17 are fixedly connected to L-shaped connecting frames 19. Both the first moving blocks 17 and the L-shaped connecting frames 19 are made of die-cast aluminum alloy, which is lightweight, high-strength, and has good processing performance, and can accurately form complex structures. Meanwhile, the corrosion resistance of aluminum alloy effectively extends the service life of components and reduces maintenance costs. Positioning plates 20 are installed on the top of both L-shaped connecting brackets 19. These positioning plates 20 are made of non-magnetic stainless steel (such as 304 stainless steel), and are processed through cutting, bending, and welding, resulting in a stable structure and strong load-bearing capacity. Vertical rods 21 are installed on the top of both positioning plates 20. These vertical rods 21 are made of seamless steel pipe with uniform wall thickness and good compressive strength, providing stable support for the positioning plates 20 and ensuring no deformation occurs during positioning. Positioning sensors 29 are installed on the bottom of both positioning plates 20. These sensors are laser displacement sensors with an accuracy of ±0.01mm, accurately capturing the core's position information. The positioning sensors 29, installed on the bottom of the positioning plates 20, can monitor the relative position of the positioning plates 20 and the mounting groove 7 in real time, feeding the position information back to the control system and providing data support for core alignment adjustment.

[0032] like Figure 2 As shown, a bevel gear 23 is fixedly connected to the outside of the first lead screw 15. Two helical gears 24 with the same transmission ratio are symmetrically meshed with the outside of the bevel gear 23. A second lead screw 25 is fixedly connected inside each of the two helical gears 24. The threads of the two second lead screws 25 have opposite directions and the same lead (ensuring that the two second moving blocks 26 move synchronously in opposite directions). The second lead screws 25 are made of the same material as the first lead screw 15. The two second lead screws 25 are rotatably connected to two other mounting plates 2 respectively. The bevel gear 23 is fixed to the outside of the first lead screw 15 and precisely meshes with the symmetrically arranged helical gears 24, realizing the synchronous rotation of the first lead screw 15 and the second lead screw 25. This transmission method has high transmission efficiency and stable transmission ratio, which can ensure the synchronous movement of the positioning plate 20 and the second positioning plate 27, providing a stable mechanical transmission basis for the core centering adjustment, avoiding positioning deviation due to asynchronous transmission, and thus achieving successful core installation in one go without multiple adjustments, significantly improving installation efficiency.

[0033] As Figure 7As shown, two second lead screws 25 are threadedly connected to second moving blocks 26. The tops of both second moving blocks 26 are fixedly connected to second positioning plates 27 via L-shaped connecting brackets 19. The second positioning plates 27 are made of the same material as the positioning plate 20. Soft pads 22, made of elastic rubber with a Shore hardness of 50-60, are installed on the sides of the positioning plates 20 and 27 that are close to each other. These pads possess good elasticity and wear resistance, effectively preventing direct rigid contact between the positioning plate 20 and the core during positioning, thus reducing friction and impact on the core surface. Each soft pad 22 is equipped with... Pressure sensor 28 is a thin-film pressure sensor, which is small in size and has a fast response speed. It can monitor the pressure value in real time during the positioning process, avoiding damage to the iron core due to excessive pressure. Pressure sensor 28 is installed on soft pad 22. During the positioning process, it can monitor the pressure value between positioning plate 20 and iron core in real time. When the pressure reaches the preset threshold, the control system will control motor 14 to stop running to prevent iron core deformation or surface damage due to excessive pressure. At the same time, it can also prevent positioning instability due to insufficient pressure, ensuring the safety and stability of iron core during centering adjustment and installation. In addition, a second limit rod 8 is fixedly connected between the two mounting plates 2. The second limit rod 8 is slidably connected to the second moving block 26. Both limit rods are made of stainless steel with polished surfaces, resulting in high smoothness and small sliding clearance with the two moving blocks. This effectively restricts the movement direction of the two moving blocks, ensuring the stability and positioning accuracy of the two lead screw drives, and providing precise motion guidance for iron core centering adjustment.

[0034] When it is necessary to position and adjust the center of the transformer core, start motor 14. The output end of motor 14 drives the first lead screw 15 to rotate through the coupling. Since the first shift block 17 is threadedly connected to the first lead screw 15 and can only move horizontally under the restriction of the first limit rod 18, the rotation of the first lead screw 15 will drive the two first shift blocks 17 to move synchronously towards or away from the core. In turn, the L-shaped connecting frame 19 will drive the two positioning plates 20 to move synchronously, realizing the initial centering adjustment of the core in the X-axis direction. At the same time, the rotation of the first lead screw 15 will drive the bevel gear 23 fixed outside it to rotate synchronously. The bevel gear 23 interacts with the symmetrically meshing helical gear 24, driving the two helical gears 24 to rotate synchronously. In turn, the second lead screw 25 fixedly connected to the helical gear 24 will rotate synchronously. The second shift block 26 is threadedly connected to the second lead screw 25 and moves horizontally under the restriction of the second limit rod 8. Therefore, the rotation of the second lead screw 25 will drive the two second shift blocks 26 to move synchronously. The L-shaped connecting frame 19 will drive the two second positioning plates 27 to move synchronously towards or away from the core, realizing the initial centering adjustment of the core in the Y-axis direction.

[0035] During the alignment process, the positioning sensor 29 monitors the relative positions of the positioning plate 20, the second positioning plate 27, and the mounting slot 7 in real time, and feeds the position data back to the control system in real time. The control system determines the deviation between the current center of the iron core and the preset center of the mounting slot 7 based on the feedback data. If there is a deviation, the control system will drive the motor 14 to precisely adjust the rotation angle of the first lead screw 15 and the second lead screw 25, thereby driving the positioning plate 20 and the second positioning plate 27 to make fine adjustments, gradually reducing the deviation between the center of the iron core and the preset center of the mounting slot 7, until the positioning sensor 29 detects that the center of the iron core and the preset center of the mounting slot 7 are completely coincident (deviation ≤ 0.03mm), completing the iron core alignment adjustment. At this time, the pressure sensor 28 simultaneously monitors the pressure between the positioning plate 20, the second positioning plate 27, and the iron core. If the pressure reaches the preset safety threshold, the control system controls the motor 14 to stop running, completing the iron core alignment and positioning operation, ensuring that the first iron core 9 can be accurately centered and installed inside the mounting slot 7.

[0036] As a further optimization of the above technical solution, such as Figure 1 , Figure 2 , Figure 7 As shown, the buffer component 4 includes an air pump 30 mounted on the base 1. Preferably, an oil-free, silent air pump is used, with a housing made of engineering plastic, which is lightweight, provides good sound insulation, and effectively reduces operating noise. The piston and cylinder inside the air pump 30 are made of wear-resistant materials, ensuring long-term stable operation and a service life of over 5000 hours. The input end of the air pump 30 is fixedly connected to an input head 31 with a dust cover. The dust cover is made of nylon material, which has good air permeability and can effectively filter dust and impurities in the air, preventing dust from entering the air pump 30 and affecting its normal operation. The output end of the air pump 30 is connected in two ways: one way is fixedly connected to a ring pipe 32, which is preferably made of PVC plastic, which has good corrosion resistance and pressure resistance, can withstand a certain air pressure, and is not easy to break. The ring pipe 32 is installed on the base 1. The other way is connected to an exhaust pipe with a control valve. The exhaust pipe is aligned with the mounting component 5. After the iron core is installed, the control valve can be opened to blow room temperature air into the mounting component 5 through the exhaust pipe to achieve auxiliary heat dissipation, so that the mounting component 5 can maintain a suitable temperature and prevent the transformer's performance and service life from being affected by excessive temperature.

[0037] Specifically, flexible hoses 33 are symmetrically installed on the outside of the ring pipe 32. The flexible hoses 33 are made of polyurethane hoses, which are flexible and can be bent at will, making them easy to install and adjust. They also have good aging resistance and can adapt to different working environments. The ends of the multiple hoses 33 away from the ring pipe 32 are all fixedly connected to the vertical rod 21 to the buffer plate 34, which is made of ABS plastic. This material has high strength, good toughness, and strong impact resistance, and can withstand the impact force of the iron core during the buffering process without being easily damaged. A buffer air cushion 35 is installed on the outside of the buffer plate 34. It is made of nitrile rubber, which has good airtightness and elasticity. It can form a stable air cushion structure after inflation, effectively absorbing the impact force. The buffer air cushion 35 is connected to the flexible hoses 33. This design allows the buffer air cushion 35 to buffer and protect the iron core from multiple directions, ensuring that the iron core is effectively protected at all angles during the centering adjustment and installation process, and avoiding excessive local force that could cause scratches or damage to the iron core.

[0038] The buffer plate 34 provides stable support for the buffer air cushion 35, preventing excessive deformation of the buffer air cushion 35 under stress. The buffer air cushion 35 utilizes the compressibility of gas to absorb impact force through gas compression when the iron core comes into contact with the buffer plate 34, thus achieving buffer protection. This combined design ensures both the buffering effect and the stability and durability of the buffer structure.

[0039] When installing the transformer core, the air pump 30 is started. The air pump 30 draws in outside air through the inlet head 31. After being filtered by the dust cover, the clean air enters the air pump 30. The air pump 30 compresses the air and delivers it to the ring pipe 32 through the output end. The ring pipe 32 evenly distributes the compressed air to each symmetrically installed hose 33. The compressed air enters the buffer air pad 35 on the buffer plate 34 through the hose 33, causing the buffer air pad 35 to inflate and bulge, thus preparing for the alignment and installation of the core.

[0040] During the installation of the iron core, when the iron core comes into contact with the buffer air cushion 35, the compressed air inside the buffer air cushion 35 will be squeezed, and the gas pressure will increase, thereby generating a reverse buffering force to absorb the impact force generated during the iron core's fall or movement, avoid direct rigid collision between the iron core and other components, and prevent scratching of the first iron core 9 and coil 10.

[0041] Mounting component 5 includes a mounting groove 7 formed inside the mounting base plate 6. A first iron core 9 is snapped into the mounting groove 7. Both the first iron core 9 and the second iron core 11 are made of high-silicon electrical steel sheets. This material has excellent magnetic permeability and low iron loss characteristics, effectively improving the magnetic performance of the transformer, reducing power loss, and increasing transformer efficiency. The electrical steel sheets are cold-rolled, resulting in uniform thickness and a smooth surface, effectively reducing eddy current losses. A coil 10 is sleeved on the outside of the first iron core 9, using high-strength enameled copper wire. Copper wire has excellent conductivity, reducing resistance loss when current flows. The enameling layer uses high-temperature resistant insulating varnish, providing good insulation performance and withstanding the high temperatures during transformer operation, preventing short circuits in the coil 10. A protrusion 13 is provided on the top of the first iron core 9.

[0042] like Figure 2 , Figure 4 As shown, the top of the first core 9 is snapped with the second core 11. The second core 11 has a groove 12 inside that corresponds to the protrusion 13. The mounting slot 7 inside the mounting base plate 6 precisely matches the outer dimensions of the first core 9. The snap-fit ​​connection facilitates installation, eliminating the need for additional fixing components, reducing installation steps, and improving efficiency. Simultaneously, the snap-fit ​​ensures the first core 9 remains fixed within the mounting slot 7, preventing core misalignment due to vibration during equipment operation, ensuring the effectiveness of initial alignment adjustments, and thus not affecting transformer performance.

[0043] In summary, when using this device, during core installation, firstly, the buffer component 4 is activated to inflate the buffer air cushion 35; then, the positioning component 3 completes the core alignment adjustment, ensuring that the first core 9 is precisely aligned with the mounting groove 7 on the mounting base plate 6, and the first core 9 is fixed in the mounting groove 7 by a snap-fit ​​method. Next, the coil 10 is tightly fitted around the outside of the first core 9, ensuring that the coil 10 is accurately positioned and that the gap between the coil 10 and the core is uniform.

[0044] Next, align the groove 12 on the top of the second iron core 11 with the protrusion 13 on the top of the first iron core 9, and slowly lower the second iron core 11 until the protrusion 13 is fully embedded in the groove 12, achieving precise assembly of the first iron core 9 and the second iron core 11. At this point, the first iron core 9 and the second iron core 11 form a complete iron core magnetic circuit. When the coil 10 is energized, the current passes through the coil 10 to generate a magnetic field. The magnetic field is transmitted in the iron core magnetic circuit, realizing the conversion of electromagnetic energy and completing the voltage transformation function of the transformer.

[0045] Throughout the installation process, the positioning component 3 ensures that the first iron core 9 is precisely positioned in the mounting slot 7 through precise centering adjustment. The buffer component 4 provides buffer protection for the first iron core 9 and the coil 10. The mounting component 5 assembles the iron core through precise structural fit. All components work together to ensure that the transformer iron core is installed accurately and stably, thus guaranteeing the normal operation of the transformer.
