Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of transformer insulator processing, and more specifically, to a grinding apparatus for processing transformer insulators. Background Technology
[0002] In the production and processing of transformer insulators, the grinding process is a crucial step in ensuring the surface precision and assembly performance of the product. Currently, the grinding equipment commonly used in the industry is mostly open or has a simple protective structure, which has significant deficiencies in protection and causes dust pollution problems.
[0003] First, there is insufficient safety protection. Traditional grinding equipment lacks a closed protective design, and the high-speed rotation of the grinding wheel easily generates flying debris, which can cause mechanical injury to operators if they accidentally come into contact with it. At the same time, glass fiber or ceramic particles from the surface of the insulator fall off during the grinding process and are directly exposed to the working environment. Long-term exposure can damage the respiratory system of workers, which does not meet the requirements of safe production. Second, there is a lack of dust collection capabilities. The dust particles generated by insulator grinding are very fine, and traditional equipment relies solely on natural settling or simple fan ventilation, which cannot effectively collect the dust. A large amount of dust not only adheres to the surface of the equipment, affecting accuracy, but also diffuses into the workshop air, leading to a deterioration of the production environment, increasing equipment maintenance costs, and increasing the risk of occupational diseases for workers. Furthermore, the existing equipment suffers from a disconnect between protective and dust collection functions. Even with the addition of baffles to some equipment, the lack of a negative pressure dust collection channel makes it difficult to prevent dust from overflowing. This situation not only hinders the improvement of processing efficiency but also contradicts the development trend of environmentally friendly production. Therefore, there is an urgent need for a specialized grinding device that integrates efficient protective and dust collection functions to solve the aforementioned industry problems.

[0022] like Figures 1-4 As shown, a grinding apparatus for processing transformer insulators is illustrated in one embodiment of this disclosure, comprising: The base 1, the moving platform 2, and the column 3 are provided. The moving platform 2 is connected to the base 1 via a horizontal linear drive, and the column 3 is fixed to the base 1. A pair of movable blocks 4 and a clamping assembly 6, wherein the movable blocks 4 are disposed on the column 3 and the clamping assembly 6 is disposed between the movable blocks 4; Grinding component 5, which is disposed on the movable stage 2; The grinding assembly 5 includes a fixed cover 5-1, which is fixed to the movable stage 2. A rotating shaft 5-2 is rotatably connected to the inner surface of the fixed cover 5-1. A drive shaft 5-3 is provided at one end of the rotating shaft 5-2. A reference block 5-4 is fixed on the rotating shaft 5-2, and a grinding disc 5-5 is fitted onto the reference block 5-4. A threaded groove 5-6 is provided at one end of the drive shaft 5-3, and a clamping sleeve 5-7 is fitted onto the other end of the drive shaft 5-3. A bolt 5-8 is inserted into the clamping sleeve 5-7, and one end of the bolt 5-8 is screwed onto the threaded groove 5-6. Within the groove 5-6, a slot 5-9 is provided on the side surface of the fixed cover 5-1. A dust collection cover 5-10 is inserted and connected into the slot 5-9. A suction pipe 5-11 is provided on the side end face of the dust collection cover 5-10. The dust collection cover 5-10 is located at the bottom of the grinding disc 5-5. A drive motor 5-12 is provided on the side surface of the fixed cover 5-1. The output end of the drive motor 5-12 is located inside the fixed cover 5-1. A transmission wheel 5-13 is provided at both the output end of the drive motor 5-12 and one end of the rotating shaft 5-2. The transmission wheels 5-13 are connected by a belt drive.
[0023] In some examples, to achieve precise grinding and dust collection of transformer insulators, a grinding assembly 5 is designed. A fixed cover 5-1 on the moving platform 2 is secured by bolts 5-8, providing protection for internal components. A rotating shaft 5-2 within the side surface is rotatably connected via bearings. A drive shaft 5-3 at one end is coaxially fixed to the rotating shaft 5-2. A reference stop 5-4 on the shaft is used to position the grinding disc 5-5, ensuring precise installation. The grinding disc 5-5 is fitted onto the reference stop 5-4. The threaded groove 5-6 at one end of the drive shaft 5-3 engages with a bolt 5-8 within a clamping sleeve 5-7. Tightening the bolt 5-8 presses the grinding disc 5-5 firmly between the reference stop 5-4 and the clamping sleeve 5-7, facilitating the replacement of grinding discs 5-5 of different specifications. The slot 5-9 on the side surface of the fixed cover 5-1 is inserted into the dust collection cover 5-10, which is located at the bottom of the grinding disc 5-5. The suction pipe 5-11 on the side end is connected to a negative pressure device to remove the dust generated during grinding. The output end of the drive motor 5-12 on the side surface of the fixed cover 5-1 is connected to the transmission wheel 5-13 at one end of the rotating shaft 5-2 via a belt, forming a transmission structure.
[0024] During operation, the drive motor 5-12 drives the rotating shaft 5-2 to rotate via a belt, and the grinding disc 5-5 rotates with the shaft to grind the insulator. The reference stop 5-4 ensures the coaxiality of the grinding disc 5-5, improving grinding accuracy. The fit between the clamping sleeve 5-7 and the bolt 5-8 ensures the stable installation of the grinding disc 5-5, preventing vibration from affecting the grinding effect. Simultaneously, the negative pressure device generates negative pressure in the dust collection hood 5-10 through the suction pipe 5-11, sucking in and collecting the grinding dust to prevent dust from spreading and polluting the environment. The detachable grinding disc 5-5 is designed to adapt to different grinding needs, improving the equipment's versatility; the directional suction of the dust collection hood 5-10 achieves centralized dust collection, improving the working environment; the belt drive structure ensures smooth drive and reduces grinding vibration; the protective function of the fixed cover 5-1 prevents dust and debris from splashing, ensuring operational safety. This component combines precise grinding with efficient dust collection to achieve high-quality grinding of transformer insulators.
[0025] like Figures 1-4 As shown, this embodiment proposes that the clamping assembly 6 includes a horizontal frame 6-1, which is vertically linearly driven and connected to the column 3. A pair of moving blocks 4 are horizontally linearly driven and connected to the horizontal frame 6-1. Each moving block 4 has a side frame 6-2 at its bottom. A sleeve 6-3 is rotatably connected to the side frame 6-2 through a round shaft. One side of the sleeve 6-3 is electrically driven to rotate. An insertion hole 6-4 is opened on the side surface of the side frame 6-2. A shield 6-5 is inserted and connected between the insertion holes 6-4.
[0026] In some examples, the clamping assembly 6 achieves stable clamping of the transformer insulator and multi-angle grinding cooperation through multi-dimensional adjustment and rotation drive. The horizontal frame 6-1 inside the column 3 is driven by a vertical linear drive device (such as a lead screw mechanism) and can be raised and lowered vertically along the column 3 to adjust the clamping height; a pair of moving blocks 4 inside the horizontal frame 6-1 are driven by a horizontal linear drive device (such as a lead screw mechanism) and can move relative to or away from each other to adjust the clamping distance. The side frames 6-2 at the bottom of the moving blocks 4 are symmetrically distributed, and are internally connected to the sleeves 6-3 by rotating round shafts. The sleeves 6-3 can clamp both ends of the insulator, and one side of the sleeve 6-3 is driven by a motor to rotate, which can drive the insulator to rotate synchronously. The insertion holes 6-4 on the side surface of the side frame 6-2 are used to insert the shield 6-5, which can surround the outside of the grinding area to further prevent dust diffusion.
[0027] During operation, based on the insulator length, the horizontal drive device moves the moving block 4 to adjust the spacing of the sleeve 6-3, clamping both ends of the insulator into the sleeve 6-3. The vertical linear drive device moves the horizontal frame 6-1 up and down, ensuring the insulator and grinding disc 5-5 are at the appropriate height. During grinding, the motor drives the sleeve 6-3 to rotate, causing the insulator to rotate, which, combined with the horizontal movement of the moving table 2, achieves uniform grinding of the entire circumference of the insulator. The shield 6-5 is inserted into the insertion hole 6-4, working with the dust collection cover 5-10 to enhance dust protection. The multi-dimensional adjustment structure adapts to the clamping requirements of insulators of different specifications, improving the equipment's applicability. The rotation drive of the sleeve 6-3 allows for full-circumference grinding of the insulator without manual flipping, improving processing efficiency. The vertical linear drive achieves precise height control, ensuring accurate grinding position. The shield 6-5's protective function reduces dust spillage, ensuring a clean working environment. This component, through flexible adjustment and rotation drive, provides stable and reliable clamping and coordination for transformer insulator grinding, improving grinding quality and efficiency.
[0028] For example, such as Figure 3 As shown, both the dust collection hood 5-10 and the shield hood 6-5 have a semi-circular cross-section.
[0029] In some examples, both the dust collection hood 5-10 and the shield hood 6-5 have semi-circular cross-sections, which can be combined to form a circular cavity. The dust collection hood 5-10 is located below, and the shield hood 6-5 covers it from above, providing comprehensive coverage of the grinding area and enhancing dust interception. The semi-circular structure adapts to the shape of the insulator, reducing wasted space while ensuring sufficient contact space between the grinding disc 5-5 and the workpiece, making it easier for dust to be drawn into the dust collection hood 5-10, improving dust removal efficiency and reducing the risk of dust spillage.
[0030] For example, such as Figure 1 As shown, telescopic covers 7 are installed at the linear drive connection points of the moving block 4, the moving platform 2, and the cross frame 6-1.
[0031] In some examples, telescopic covers 7, made of foldable dustproof material, are installed at the linear drive connection points of the moving block 4, the moving stage 2, and the crossbeam 6-1. The telescopic covers 7 can extend and retract with the movement of the drive components, completely covering the drive connection points, preventing grinding dust from entering the drive mechanism, avoiding component wear or jamming, extending the service life of the equipment, reducing maintenance frequency, and ensuring smooth and accurate linear drive.
[0032] In practical use: Place both ends of the transformer insulator into the sleeve 6-3, adjust the spacing of the horizontally driven moving block 4 to clamp it, and raise and lower the vertically linearly driven crossbeam 6-1 to the appropriate height. The drive motor 5-12 drives the rotating shaft 5-2 to rotate via a belt, causing the grinding disc 5-5 to rotate with the shaft. The moving table 2 moves horizontally in coordination with the rotation of the sleeve 6-3, achieving full-circumference grinding of the insulator. The dust collection hood 5-10 is inserted into the slot 5-9, and the suction pipe 5-11 is connected to a negative pressure device to remove dust. The shield hood 6-5 is inserted into the insertion hole 6-4 to form a closed space. When replacing the grinding disc 5-5, simply loosen the bolt 5-8 and remove the clamping sleeve 5-7. The telescopic cover 7 protects all drive connections from dust contamination, achieving precise grinding and efficient dust removal throughout the process.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
