Description

Technical Field

[0001] This invention relates to the field of machine tool technology, and in particular to a cutting device for the production of current transformer cores. Background Technology

[0002] The field of machine tool technology encompasses related technical directions such as equipment design, manufacturing process optimization, and machining method research for processing various workpieces. Its core content involves processing raw materials into workpieces that meet precision requirements through various cutting and grinding methods. This covers key technical aspects such as equipment structure design, transmission system optimization, tool selection, and machining parameter control. It is widely used in multiple industries, including machinery manufacturing, power equipment, and the automotive industry, providing fundamental machining support for the production of parts for various industrial products.

[0003] One type of cutting device used in the production of current transformer cores refers to a specialized piece of equipment specifically designed for cutting and processing core materials during the production process of current transformer cores. Its technical aspects include fixed-length cutting of core raw materials and precise slitting of core laminations. Specifically, it achieves stable transport of core materials through a feeding mechanism, fixes the position of the core materials using positioning components, cuts the core materials according to preset dimensions using cutting tools, ensures the accuracy of the material's movement trajectory during cutting through a guiding structure, and adjusts the relative position between the cutting tool and the material through an adjustment mechanism to adapt to the cutting requirements of different core specifications.

[0004] Existing technologies can only achieve basic conveying, positioning, cutting, guiding, and adjustment. In actual processing, insufficient clamping stability can easily lead to core displacement and deformation. The lack of debris protection measures can easily cause environmental dust pollution, threatening the safety of operators. Without subsequent auxiliary processing structures, it is impossible to process the cut core, affecting processing quality. The adaptability adjustment method is singular and cannot meet the processing needs of various core specifications. For example, unstable clamping can lead to cutting size deviations, affecting subsequent core assembly. Scattered debris can pollute the workshop environment and harm the respiratory system of operators. Summary of the Invention

[0005] The main objective of this invention is to provide a cutting device for the production of current transformer cores that can effectively solve the problems mentioned in the background art.

[0010] Preferably, the driving assembly includes a slider slidably mounted on the inner wall of the lifting guide rail. A slide block is rotatably connected to the inner surface of the slider. Buffer grooves are distributed in a ring on the side of the slide block near the post-processing structure. A central groove is formed on the side of the slide block near the post-processing structure. The inner walls of the two buffer grooves and the central groove are slidably connected to the clamping assembly. A cross transmission rod extending through the central groove and into the inner cavity of the slide block is slidably connected to the inner surface of the central groove. The end of the cross transmission rod away from the clamping assembly is driven by a motor located on one side of the slider.

[0011] Preferably, the inner cavity of the slide block is slidably connected with a plurality of connecting rods in a ring. Each of the connecting rods is fixedly connected to a friction plate on the side near the inner wall of the slide block. Each of the friction plates is provided with a buffer spring on the side near the center of the slide block to limit the position of the friction plate. When the connecting rod is not under force, the friction plate separates from the inner wall of the slide block under the action of the buffer spring. The outer surface of the cross transmission rod located in the inner cavity of the slide block is fixedly connected to a conical platform that fits against the inclined part of the adjacent connecting rod. The side of the conical platform near the inner wall of the slider is rotatably connected to a spring ring that is fixedly connected to the slider.

Two cables on the same side are wound around the sides of the adjacent drive rods. When the winding shaft rotates, the cables are wound around the surface of the winding shaft and drive the drive rods to rotate through friction.

[0014] Preferably, the inner wall clamping member includes an L-shaped rod fixedly connected to the outer surface of the drive rod. A wedge-shaped block is slidably connected to the inner cavity of the vertical portion of the L-shaped rod. One end of the wedge-shaped block near the clamp seat passes through the L-shaped rod and is fixedly connected to an arc-shaped block conforming to the inner wall of the iron core. A spherical rod conforming to the inclined surface of the wedge-shaped block is provided in the inner cavity of the vertical portion of the L-shaped rod. A cable wrapped around the outer surface of the drive rod is fixedly connected to the upper end of the spherical rod. Connecting rods are symmetrically fixedly connected to the end of the arc-shaped block away from the clamp seat. The two connecting rods... A spring plate is fixedly connected to the end of the L-shaped rod away from the clamp seat. The inner cavity of the horizontal part of the L-shaped rod is slidably connected to a wedge block two that is fixedly connected to the outer surface of the cable one through a spring. The inclined surface of the wedge block two is provided with a spherical rod that penetrates the inner cavity of the horizontal part of the L-shaped rod. The lower end of the spherical rod is fixedly connected to a pressure block for fitting against the upper and lower surfaces of the iron core. When the L-shaped rod stops rotating, the drive rod continues to rotate, driving the wedge block two and the round rod to move through the cable one, and pushing the pressure block and the arc block one to move closer to the surface of the iron core.

[0015] Preferably, the post-processing structure includes a support box installed on the upper end of the telescopic base. The inner wall of the support box has four rectangularly distributed limiting grooves. An isolation plate is fixedly installed on the inner wall of the support box. A circulation pump is fixedly installed at the lower end of the support box. A grinding component is provided on the inner walls of the four limiting grooves and the inner wall of the support box. A cable three driven by a winch is provided in the inner cavity of the support box to drive the grinding component to slide within the limiting grooves.

[0016] Preferably, the grinding assembly includes two grinding plates symmetrically distributed on the left and right. The two grinding plates are rotatably connected to a central plate that is connected to the output end of the circulating pump through a bellows on the side that is close to each other. The central plate has several through holes arranged in an array at both ends that communicate with its inner cavity. The lower end of the central plate is fixedly connected to a multi-stage telescopic rod that is fixedly connected to the bottom wall of the inner cavity of the support box. The two grinding plates are provided with rollers that slide with adjacent limiting grooves and are connected to the cable by a slip ring on the side that is far apart from each other.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This invention achieves stable clamping and precise auxiliary processing of the transformer core through the cooperation of the clamping structure and the post-processing structure. The clamping structure can stably clamp the core to ensure the smooth progress of the cutting process. The grinding component of the post-processing structure is initially laid flat against the upper end of the support box, which can stably support the core and prevent placement deviation, while assisting the clamping structure in subsequent grinding processing. Combined with the closed design of the cutting structure, the outer shell, and the shielding door, it can block cutting debris and dust, protect the safety of operators, and reduce environmental dust pollution.

[0019] 2. This invention achieves precise fitting and stable clamping of the iron core through the cooperation of the telescopic base of the clamping structure, the lifting guide rail, the drive component, and the clamping component. The telescopic base can adjust the overall height, the lifting guide rail drives the drive component and the clamping component to precisely align with the iron core, the slider of the drive component provides stable support, the cross transmission rod stably transmits power, and the inner wall clamping parts of the clamping component and the spring limit rod and other components form multi-directional clamping, dispersing the clamping force to avoid deformation of the iron core, and the spring plate provides buffer protection, thus ensuring the overall clamping balance and stability and protecting the integrity of the iron core.

[0020] 3. This invention utilizes a clutch structure formed by the cooperation of the slide block, the internal conical platform, the connecting rod, the friction plate, the buffer spring, and the spring ring to achieve flexible switching between clamping and rotational actions. No additional drive mechanism is required, simplifying the overall structure of the equipment and reducing production costs. The buffer spring can quickly reset the friction plate, ensuring timely separation between the friction plate and the inner wall of the slide block. The spring ring provides stable support and limits the conical platform, ensuring smooth movement, effectively improving the continuity of action switching, and guaranteeing smooth equipment operation.

[0021] 4. This invention utilizes the cooperation of the support box in the post-processing structure with the grinding assembly, the limiting groove, and the cable three. The support box provides a stable installation foundation for each component, the limiting groove ensures smooth and controllable movement of the grinding assembly, and the cable three precisely adjusts the position of the grinding assembly. The grinding plate of the grinding assembly initially lays flat to stably support the iron core and prevent displacement. During grinding, it forms an "n" shape with the center plate to achieve all-round grinding. The multi-stage telescopic rod prevents dead spots and ensures smooth operation. The isolation plate prevents debris from entering critical components. The circulating pump and the through hole in the center plate deliver grinding fluid, cooling the iron core and removing debris, improving the grinding effect, extending the life of the grinding plate, and ensuring the normal operation of the equipment.

Detailed Implementation

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1: A cutting device for the production of current transformer cores, see reference. Figure 1 and Figure 2 The device includes a table 1, an outer shell 3 located on the upper part of the table 1, a shielding door 2 located at the front end of the outer shell 3, and a controller 4 located at the front end of the outer shell 3. A clamping structure 5 for holding the transformer core is located in the middle of the upper part of the table 1. A post-processing structure 6 for supporting the transformer core and assisting the clamping structure 5 in grinding is located on the upper end of the clamping structure 5. A cutting structure 7 for cutting the transformer core is located on the top wall of the inner cavity of the outer shell 3. After the equipment is started, the shielding door 2 will close first, and the outer shell 3 and the shielding door 2 will form a closed space, which can effectively block the debris and dust generated by the subsequent cutting process, thus protecting the safety of the operators and reducing environmental dust pollution. The grinding component in the post-processing structure 6 is initially laid flat against the upper end of the support box, which can provide stable support for the transformer core placed on it, preventing the core from shifting and ensuring the smooth progress of subsequent clamping and cutting processes. The controller 4 is used to allow the operator to issue various operation instructions and achieve precise control of the movement of each structure of the entire device.

[0035] For further details, please refer to [link / reference]. Figure 3The cutting structure 7 includes a drive platform 71 installed on the top wall of the inner cavity of the shielding door 2. Telescopic rods 72 are fixedly connected to both ends of the drive platform 71. A saw rope 73, suspended above the clamping structure 5, is installed in the inner cavity of the drive platform 71 and the inner cavities of the telescopic rods 72 on both sides. Once the clamping structure 5 has successfully clamped the iron core, the cutting structure 7 is activated. The drive platform 71 then drives the telescopic rods 72 to move, adjusting the height and tension of the saw rope 73 to match the specifications of the iron core to be cut. The saw rope 73 then moves at high speed to cut the iron core. The flexible adjustment of the telescopic rods 72 allows for the adaptation to the cutting needs of iron cores of different specifications, effectively enhancing the equipment's versatility. The design of the saw rope 73 suspended above the clamping structure 5 ensures precise contact with the iron core during the cutting process, guaranteeing the smooth progress of the cutting operation.

[0036] In the operation of this embodiment, the clamping structure 5 and the post-processing structure 6 work together to achieve stable clamping and precise auxiliary processing of the transformer core. The clamping structure 5 can stably clamp the core to ensure the smooth progress of the cutting process. The grinding component of the post-processing structure 6 is initially laid flat against the upper end of the support box, which can stably support the core and prevent placement deviation, while also assisting the clamping structure 5 in subsequent grinding. With the closed design of the cutting structure 7, the outer shell 3, and the shielding door 2, cutting debris and dust can be blocked to protect the safety of operators and reduce environmental dust pollution. The telescopic rod 72 of the cutting structure 7 can be flexibly adjusted to adapt to the cutting needs of different specifications of cores, enhancing the versatility of the equipment.

[0037] Example 2: Based on Example 1, this example achieves precise fitting and stable clamping of the iron core through the cooperation of the telescopic base 51, lifting guide rail 52, drive component 53, and clamping component 54 of the clamping structure 5. The telescopic base 51 can adjust the overall height, and the lifting guide rail 52 drives the drive component 53 and clamping component 54 to precisely align with the iron core. The slider 531 of the drive component 53 provides stable support, and the cross transmission rod 538 stably transmits power. The inner wall clamping member 541 of the clamping component 54 and the spring limit rod 544 form multi-directional clamping, dispersing the clamping force to prevent deformation of the iron core. The spring plate 5412 provides buffer protection, ensuring the overall clamping balance and stability, and protecting the integrity of the iron core.

[0038] For further details, please refer to [link / reference]. Figure 4The clamping structure 5 includes a telescopic base 51 installed on the upper end of the table 1. Lifting guide rails 52 are symmetrically fixedly installed on the upper end of the telescopic base 51. Drive components 53 are slidably connected to the inner walls of both lifting guide rails 52 via a lifting mechanism. Clamping components 54 are symmetrically distributed on the side of each drive component 53 that is close to the other. As the core clamping component, the telescopic base 51 of the clamping structure 5 can adjust the overall height of the entire clamping structure, providing a basis for adapting the structure height in subsequent processes. The lifting guide rails 52 drive the drive components 53 up and down via the lifting mechanism, thereby moving the clamping components 54 to a height position suitable for the iron core, ensuring that the clamping components 54 can accurately align with the iron core for stable clamping. The two symmetrically distributed drive components 53 and clamping components 54 cooperate to apply clamping force from both sides of the iron core, ensuring the balance and stability of the clamping and preventing iron core displacement caused by clamping in one direction.

[0039] For further details, please refer to [link / reference]. Figure 5 and Figure 6 The drive assembly 53 includes a slider 531 slidably mounted on the inner wall of the lifting guide rail 52. A slide block 532 is rotatably connected to the inner surface of the slider 531. Buffer grooves 5321 are annularly distributed on the side of the slide block 532 near the post-processing structure 6. A central groove 5322 is also formed on the side of the slide block 532 near the post-processing structure 6. The inner walls of the two buffer grooves 5321 and the central groove 5322 are slidably connected to the clamping assembly 54. A cross transmission rod 538, extending through the central groove 5322 and into the inner cavity of the slide block 532, is slidably connected to the inner surface of the central groove 5322. The cross transmission rod 538 is located away from the clamping assembly. One end of 54 is driven by a motor located on one side of slider 531. Slider 531 provides a stable mounting and support base for components such as slide block 532 and cross transmission rod 538. Its sliding connection with lifting guide rail 52 realizes the overall lifting and moving of the drive assembly. Buffer groove 5321 and center groove 5322 provide precise limit guidance for the sliding of clamping assembly 54, ensuring that the action of clamping assembly 54 is stable and controllable. The motor drives cross transmission rod 538 to rotate, providing a power source for the subsequent clamping action of clamping assembly 54 and the rotation action of iron core, ensuring the stable output of power in each process.

[0040] For further details, please refer to [link / reference]. Figure 5 and Figure 6The clamping assembly 54 includes telescopic rods 543 symmetrically distributed vertically and slidably connected to the inner surface of adjacent central grooves 5322. The output ends of the two telescopic rods 543 are fixedly connected to a clamping seat 542. An arc-shaped block 548 is slidably connected to the side of the clamping seat 542 away from the slide block 532. A spring-loaded limiting rod 544, penetrating the clamping seat 542 and slidably connected to the inner surface of the buffer groove 5321, is rotatably connected to the rear end of the arc-shaped block 548. A connecting hole adapted to the cross-drive rod 538 is provided on the side of the spring-loaded limiting rod 544 near the cross-drive rod 538. Inner wall clamping members 541 are symmetrically rotatably connected to the upper and lower ends of the clamping seat 542. During the cutting process, the cross-drive rod 538 is located inside the connecting hole, at which time the spring-loaded limiting rod 544 and the cross-drive rod 538 are stable. The connection ensures precise transmission of clamping actions. During the grinding process, the spring limit rod 544 presses the conical platform 533 through the cross transmission rod 538, and the conical platform 533 presses the connecting rod 535, providing power for the switching of the clutch structure. The telescopic rod 543 can flexibly adjust the position of the clamp seat 542 according to the shape and size of the iron core, ensuring that the clamp seat 542 drives the inner wall clamping component 541 to always be in the appropriate clamping and grinding position for the iron core, improving clamping stability and grinding quality. The arc block 548 can assist the inner wall clamping component 541 in limiting the iron core, further enhancing the stability of the clamping. The connecting hole of the spring limit rod 544 and the cross transmission rod 538 are adapted to ensure that the power can be accurately transmitted to the clamping assembly 54, ensuring that each action is carried out in an orderly manner.

[0041] For further details, please refer to [link / reference]. Figure 6 A winding shaft 547 is rotatably connected to the center of the inner cavity of the clamping seat 542 and slidably connected to the central axis of the spring limiting rod 544. Four cables 546 are wound around the outer surface of the winding shaft 547. The upper and lower ends of the clamping seat 542 are rotatably connected to drive rods 545 that drive adjacent inner wall clamping parts 541 through torsion springs. Two cables 546 on the same side are wound around the two sides of the adjacent drive rods 545. When the winding shaft 547 rotates, the cables 546 are wound around the surface of the winding shaft 547 and drive the drive rods through friction. When the winding shaft 547 stops rotating and the second cable 546 is released, the torsion spring can drive the drive rod 545 to reset, preparing for the subsequent release of the iron core by the clamping assembly 544. The winding shaft 547 converts its own rotational power into the rotational power of the drive rod 545 through the second cable 546. This power transmission method is smooth and precise, ensuring that the drive rod 545 drives the inner wall clamping component 541 to move synchronously, ensuring the symmetry and stability of the iron core clamping, and avoiding iron core deformation due to uneven clamping force.

[0042] For further details, please refer to [link / reference]. Figure 7The inner wall clamping member 541 includes an L-shaped rod 5411 fixedly connected to the outer surface of the drive rod 545. A wedge-shaped block 5413 is slidably connected to the inner cavity of the vertical part of the L-shaped rod 5411. One end of the wedge-shaped block 5413 near the clamp seat 542 passes through the L-shaped rod 5411 and is fixedly connected to an arc-shaped block 5415 that fits against the inner wall of the iron core. A spherical rod 5417 that fits against the inclined surface of the wedge-shaped block 5413 is provided in the inner cavity of the vertical part of the L-shaped rod 5411. The upper end of the spherical rod 5417 is fixedly connected to a component that is wound around the outer surface of the drive rod 545. Cable 5410 and arc-shaped block 5415 are symmetrically fixed to one end away from clamp seat 542 with connecting rod 5414. Both connecting rods 5414 are fixedly connected to a spring plate 5412 located at the end of L-shaped rod 5411 away from clamp seat 542. A wedge-shaped block 5416, fixedly connected to the outer surface of cable 5410, is slidably connected to the inner cavity of the horizontal portion of L-shaped rod 5411 via a spring. A spherical rod 5417, penetrating the inner cavity of the horizontal portion of L-shaped rod 5411, is provided on the inclined surface of wedge-shaped block 5416. The lower end of 417 is fixedly connected to a pressing block 5418 for conforming to the upper and lower surfaces of the iron core. When the drive rod 545 rotates, it drives the L-shaped rod 5411 to rotate synchronously, causing the arc-shaped block 5413 to initially approach the inner wall of the iron core. When the L-shaped rod 5411 stops rotating, the drive rod 545 continues to rotate, driving the wedge block 5416 to move via the cable 5410. The wedge block 5416 pushes the pressing block 5418 closer to the upper and lower surfaces of the iron core via the ball rod 5417. At the same time, the cable 5410 drives the wedge block 5413 to move, causing the arc-shaped block 5413 to initially approach the inner wall of the iron core. The first arc-shaped block 5415 fits tightly against the inner wall of the iron core, achieving multi-directional stable clamping of the iron core. The spring plate 5412 can act as a buffer when the first arc-shaped block 5415 fits against the iron core, avoiding rigid contact between the first arc-shaped block 5415 and the iron core, which would cause damage to the iron core. The spring in the inner cavity of the horizontal part of the L-shaped rod 5411 can drive the second wedge block 5416 to reset, making it easier to release the iron core later. This multi-contact clamping design can effectively disperse the clamping force and avoid excessive local pressure that could cause deformation of the iron core, thus protecting the integrity of the iron core while ensuring clamping stability.

[0043] In Example 3, based on Example 2, a clutch structure is formed by the cooperation of the slide 532, the internal conical platform 533, the connecting rod 535, the friction plate 536, the buffer spring 537, and the spring ring 534. This allows for flexible switching between clamping and rotational actions without the need for an additional drive mechanism, simplifying the overall structure of the equipment and reducing production costs. The buffer spring 537 can drive the friction plate 536 to quickly reset, ensuring that the friction plate 536 separates from the inner wall of the slide 532 in a timely manner. The spring ring 534 provides stable support and limits the conical platform 533, ensuring its smooth movement, effectively improving the continuity of action switching, and ensuring smooth operation of the equipment.

[0044] For further details, please refer to [link / reference]. Figure 8The inner cavity of the slide block 532 is slidably connected with several connecting rods 535 arranged in a ring. Each connecting rod 535 is fixedly connected to a friction plate 536 on the side near the inner wall of the slide block 532. Each friction plate 536 is provided with a buffer spring 537 on the side near the center of the slide block 532 to limit its position. When the connecting rods 535 are not under force, the friction plates 536 separate from the inner wall of the slide block 532 under the action of the buffer springs 537. The outer surface of the cross transmission rod 538, located within the inner cavity of the slide block 532, is fixedly connected to a conical platform 533 that fits against the inclined surface of the adjacent connecting rod 535. The side of the conical platform 533 near the inner wall of the slider 531 is rotatably connected to a spring ring 534 fixedly connected to the slider 531. When the cross transmission rod 538 moves towards the slider 531, the conical platform 533 moves through the connecting rods 535... The friction plate 536 is pushed to fit against the inner wall of the slide 532, and the friction force drives the slide 532 and the cross transmission rod 538 to rotate synchronously. The buffer spring 537 can quickly drive the friction plate 536 to reset when the connecting rod 535 is not under force, ensuring that the friction plate 536 separates from the inner wall of the slide 532 in time. The spring ring 534 provides stable support and limit for the conical platform 533, ensuring that the conical platform 533 moves smoothly under the drive of the cross transmission rod 538. The slide 532 and its internal components such as the conical platform 533, the connecting rod 535, and the friction plate 536 constitute a clutch structure. This structure realizes flexible switching between clamping and rotation actions without the need for an additional drive mechanism. It simplifies the overall structure of the equipment, reduces production costs, and effectively improves the continuity of action switching, ensuring smooth operation of the equipment.

[0045] Example 4: Based on Example 3, this example utilizes the cooperation of the support box 61 of the post-processing structure 6 with the grinding assembly 63, the limiting groove 65, and the cable 66. The support box 61 provides a stable installation base for each component, the limiting groove 65 ensures smooth and controllable movement of the grinding assembly 63, and the cable 66 precisely adjusts the position of the grinding assembly 63. The grinding plate 631 of the grinding assembly 63 initially lays flat to stably support the iron core and prevent displacement. During grinding, it forms an "n" shape with the center plate 632 to achieve all-round grinding. The multi-stage telescopic rod 634 prevents dead spots and ensures smooth operation. The isolation plate 62 prevents debris from entering key components. The circulating pump 64 and the through hole 633 of the center plate 632 deliver grinding fluid, cooling the iron core and removing debris, improving the grinding effect, extending the life of the grinding plate 631, and ensuring the normal operation of the equipment.

[0046] For further details, please refer to [link / reference]. Figure 9The post-processing structure 6 includes a support box 61 mounted on the upper end of the telescopic base 51. Four rectangular limiting grooves 65 are provided on the inner wall of the support box 61. An isolation plate 62 is fixedly installed on the inner wall of the support box 61. A circulation pump 64 is fixedly installed at the lower end of the support box 61. A grinding assembly 63 is provided on the inner walls of the four limiting grooves 65 and the inner wall of the support box 61. A cable 66, driven by a winch, propels the grinding assembly 63 to slide within the limiting grooves 65. The support box 61 provides a stable mounting base for the grinding assembly 63, circulation pump 64, and other components. The limiting grooves 65 inside the support box serve as the grinding assembly... The movement of component 63 provides precise guidance, ensuring smooth and controllable movement of the grinding assembly 63 and ensuring that the grinding plate can stably fit the iron core. The isolation plate 62 is used to filter the grinding fluid, which can effectively prevent the grinding debris generated from entering the support box 61, avoiding the debris from affecting the normal operation of other components in the support box 61. At the same time, it can also prevent debris from entering key components such as the circulation pump 64, avoiding the failure of key components due to debris blockage or wear, and ensuring the normal operation of the equipment. The winch drive cable 66 drives the grinding assembly 63 to move, and the power transmission is stable and controllable, which can precisely adjust the position of the grinding assembly 63 to meet different grinding needs.

[0047] For further details, please refer to [link / reference]. Figure 10 The grinding assembly 63 includes two grinding plates 631 symmetrically distributed on the left and right. The two grinding plates 631 are rotatably connected to a central plate 632, which is connected to the output end of the circulating pump 64 via a bellows, on the side closest to each other. The central plate 632 has several through holes 633 arranged in an array on both its left and right ends, communicating with its inner cavity. The lower end of the central plate 632 is fixedly connected to a multi-stage telescopic rod 634, which is fixedly connected to the bottom wall of the inner cavity of the support box 61. The two grinding plates 631 are provided with rollers that slide with adjacent limiting grooves 65 and are connected to the cable 66 via slip rings on the side furthest from each other at the front and rear ends. In the initial state, the two grinding plates 631 are laid flat against the upper end of the support box 61, which can stably support the iron core and prevent the iron core from shifting. When the grinding process starts, the winch drives the cable 66 to pull the rollers of the grinding assembly 63 to slide in the limiting grooves 65. The two flat grinding plates 631 are brought closer to the center of the support box 61 and eventually become vertical, forming an "n" shape with the center plate 632 to fit the iron core surface, achieving all-round grinding of the iron core surface. The spring plate at the top of the multi-stage telescopic rod 634 can avoid dead points during the movement of the grinding assembly 63, ensuring smooth movement and fit. During the grinding process, the circulation pump 64 is activated to deliver grinding fluid to the center plate 632. The grinding fluid is evenly sprayed through the through hole 633 of the center plate 632 onto the contact area between the iron core and the grinding plate 631, which not only cools down the iron core and reduces the impact of high temperature on the iron core performance, but also removes grinding debris and reduces frictional resistance, improving the grinding effect and extending the service life of the grinding plate 631. The corrugated pipe can adapt to the needs of the center plate 632 moving with the grinding assembly 63, ensuring stable delivery of grinding fluid without leakage.
