Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of polishing equipment, more specifically, relates to a multi-surface processing equipment for hollow cylinder magnetic cores. BACKGROUND

[0002] In the field of polishing hollow cylinder magnetic cores, the current technical means has a series of problems to be solved, which seriously limits the polishing efficiency, quality and universality of the equipment.

[0003] Firstly, traditional polishing equipment often cannot realize synchronous multi-surface polishing. Most equipment can only polish a single surface of the hollow cylinder magnetic core. If the inner and outer surfaces need to be polished at the same time, multiple clamping and operations are required, which not only consumes a lot of time, but also causes position deviation of the magnetic core due to multiple clamping, affecting the polishing precision and leading to low overall polishing processing capacity.

[0004] The equipment has poor self-adaptability to different sizes of hollow cylinder magnetic cores. Existing polishing equipment is usually designed for specific size magnetic cores. For hollow cylinder magnetic cores of different sizes, there is a lack of effective self-adaptive adjustment mechanism. The operator needs to manually replace the appropriate clamp or adjust the equipment parameters, which is complex and time-consuming, and cannot meet the diversified production needs.

[0005] The diversity of polishing capacity is insufficient. The traditional equipment has a single polishing method, which cannot meet the different polishing needs. Whether the polishing degree or the polishing method changes is limited by the structure and function of the equipment, and cannot flexibly cope with the polishing tasks of hollow cylinder magnetic cores with different process requirements.

[0006] It is difficult to ensure the polishing precision. In the polishing process, the traditional equipment cannot adaptively adjust the polishing contact force according to the surface characteristics of the magnetic core and the actual needs. This may cause uneven polishing force, resulting in local over-polishing or under-polishing, which seriously affects the polishing quality and precision of the hollow cylinder magnetic core.

[0007] It is difficult to meet the needs of different polishing forces. Different hollow cylinder magnetic cores may require different polishing forces during polishing, such as different force requirements for rough polishing and fine polishing. However, existing equipment often lacks effective polishing force adjustment mechanism, making it difficult for operators to accurately control the pressure between the polishing roller and the magnetic core, affecting the polishing effect and product quality.

[0008] Limited polishing range is also a common problem. Traditional polishing equipment cannot fully cover the entire surface when polishing the surface of the hollow cylinder magnetic core, resulting in incomplete polishing in some areas, which needs to be manually processed again, reducing production efficiency and making it difficult to ensure the consistency of polishing quality.

[0009] In addition, the traditional equipment lacks corresponding inner diameter self-adaptive polishing capability for hollow cylinder magnetic cores with different inner diameters. The fixed-size polishing components cannot meet the polishing requirements of magnetic cores with different inner diameters, limiting the universality and application range of the equipment.

[0010] In terms of fixing and supporting of the hollow cylinder magnetic core, the traditional method also has defects. The commonly used fixing method cannot adapt to hollow cylinder magnetic cores of different sizes and heights, and the fixing is not firm, which can cause displacement of the magnetic core during polishing, affecting the polishing precision. At the same time, there is a lack of self-adaptive bottom support capability for magnetic cores of different heights, further reducing the applicability of the equipment.

[0011] In summary, the existing hollow cylinder magnetic core polishing technology has significant deficiencies in synchronous multi-surface polishing, self-adaptation of different size magnetic cores, polishing capability diversity, polishing precision, polishing force adjustment, polishing range, inner diameter self-adaptive polishing, and magnetic core fixing and supporting, etc. It cannot meet the needs of modern manufacturing industry for efficient, high-precision, and diversified polishing of hollow cylinder magnetic cores.

[0017] Compared with the prior art, the polishing equipment has the following beneficial effects:

[0018] In this invention, a hollow cylindrical magnetic core is fitted over an inner polishing disc. A fixing airbag expands and fixes the inner wall of the top of the hollow cylindrical magnetic core. Then, the main drive motor is started, which drives the transmission rod to rotate. The rotation of the transmission rod drives the hollow cylindrical magnetic core to rotate through the fixing airbag. Since the two micro motors at the top of the main drive motor are stationary, the two inner polishing discs at the top and bottom remain stationary. Multiple inner polishing discs polish the inner wall of the hollow cylindrical magnetic core. At the same time, the mounting frame is started, which drives the polishing rollers to move closer to the hollow cylindrical magnetic core. Since the hollow cylindrical magnetic core is rotating, multiple polishing rollers at the front end of the mounting frame polish the outer surface of the hollow cylindrical magnetic core, thereby achieving simultaneous multi-face polishing and further improving the polishing capability.

[0019] In this invention, during use, since different hollow cylindrical magnetic cores are of different sizes, the first drive motor on the inner wall of the first fixed frame can be activated. The operation of the first drive motor drives the first sliding frame to move through the threaded rod. The two sides of the first sliding frame slide outside the two first support frames. The movement of the first sliding frame can stably drive the horizontal drive frame and the mounting frame above to move, thereby achieving the grinding of hollow cylindrical magnetic cores of different sizes, and further improving the adaptability to hollow cylindrical magnetic cores of different sizes.

[0020] In this invention, when the horizontal drive frame between the mounting frame and the first sliding frame is in operation, it can be driven by a motor to rotate the wheel belt drive frame. The rotation of the wheel belt drive frame drives the drive belt to move, and the movement of the drive belt drives the top horizontal moving frame to move left and right. The movement of the horizontal moving frame drives the mounting frame to move left and right, and the movement of the mounting frame drives the three grinding rollers at the end to move horizontally. The horizontal movement of the grinding rollers can perform multiple grindings on the hollow cylindrical magnetic core, thereby achieving different types of grinding capabilities and improving the coarseness of a single grinding.

[0021] In this invention, when the hollow cylindrical magnetic core rotates and contacts the grinding roller, the grinding roller will react to grind the surface of the hollow cylindrical magnetic core. There is a first spring between the moving frame on the back of each grinding roller and the inner wall of the inner connecting frame. Therefore, when hollow cylindrical magnetic cores of different sizes come into contact with the grinding roller, the grinding roller will adaptively adjust the contact force, thereby improving the fineness of the grinding.

[0022] In this invention, since different hollow cylindrical magnetic cores require different grinding forces, a second drive motor behind each grinding roller is activated during grinding. The activation of the second drive motor can move the grinding roller forward or backward via a first spring, thereby adjusting the distance between the grinding rollers and increasing or decreasing the pressure of the grinding rollers on the hollow cylindrical magnetic core. This satisfies the grinding requirements of different grinding rollers. For example, when the first grinding roller requires rough grinding, the inner connecting frame causes the grinding roller to adhere more tightly to the hollow cylindrical magnetic core, thereby increasing the grinding force. When the second or third grinding roller is used for fine grinding, the inner connecting frame causes the grinding roller to adhere more loosely to the hollow cylindrical magnetic core, thereby allowing for light grinding.

[0023] In this invention, during use, the third drive motor starts and drives the second sliding frame to move. The second sliding frame slides outside the two second support frames. The movement of the second sliding frame will drive the main drive motor to move. The movement of the main drive motor will drive the top hollow cylindrical magnetic core to move. The hollow cylindrical magnetic core can move up or down to fully contact the multiple grinding rollers, thereby increasing the grinding range of the grinding rollers on the surface of the hollow cylindrical magnetic core and further improving the overall grinding capability.

[0024] In this invention, two inner slides can move inside a fixed chassis. Therefore, when installing a hollow cylindrical magnetic core, the two inner grinding discs are pushed closer together, and then the hollow cylindrical magnetic core is fitted over the two inner grinding discs. Subsequently, the second spring between the two inner slides drives the inner grinding discs on both sides to fit against the inner wall of the hollow cylindrical magnetic core through elastic force. Both inner slides can slide outside the inner slide rod. By designing the inner grinding discs on both sides to be adjustable in distance, hollow cylindrical magnetic cores with different inner diameters can be ground, further improving the grinding of different types of hollow cylindrical magnetic cores. During grinding, two micro motors are activated, which drive the inner grinding discs on both sides to move up or down. The upward or downward movement of multiple inner grinding discs can grind the inside of the hollow cylindrical magnetic core. There are two inner grinding discs on each side, and different types of inner grinding discs can be installed on the two inner grinding discs on each side, thereby achieving grinding of various finenesses.

[0025] In this invention, during the installation of the hollow cylindrical magnetic core, the inside of the top of the hollow cylindrical magnetic core contacts the fixing airbag. Subsequently, the inflator inflates the fixing airbag, causing it to expand and fit tightly against the inner wall of the hollow cylindrical magnetic core. At this time, the rotation of the transmission rod can drive the hollow cylindrical magnetic core to rotate through the fixing airbag. By using an inflatable fixing airbag to fix the hollow cylindrical magnetic core, it can accommodate hollow cylindrical magnetic cores of different sizes, thus improving the connection capability. Since different hollow cylindrical magnetic cores have different heights, the upper support frame can provide better bottom support for the hollow cylindrical magnetic core. When encountering a shorter hollow cylindrical magnetic core, the third spring below the upper support frame can provide adaptive support capability. Attached Figure Description

[0036] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0037] Please see Figures 1-9This invention provides a multi-faceted processing device for hollow cylindrical magnetic cores, including a grinding device body 1 and a hollow cylindrical magnetic core 48. A main drive motor 35, movable vertically, is installed inside the grinding device body 1 near its rear side. A first drive motor 12, a second drive motor 26, and a third drive motor 33 each consist of a motor and a threaded rod, with the threaded rod fixed to the output shaft end of the motor. A transmission rod 36 is fixedly installed at the output shaft end of the main drive motor 35. A fixed base 37 is fixedly installed on the top of the main drive motor 35. The transmission rod 36 rotatably passes through the fixed base 37. Two micro motors 41 are arranged on the surface of the fixed base 37, and two inner grinding discs 42 are installed outside the lead screw at the end of each micro motor 41. A horizontally movable mounting frame 2 is installed inside the grinding device body 1 near its front side. At least two sets of outer connecting frames 23 are installed inside the mounting frame 2, and each set of outer connecting frames 23 has an inner connecting frame 25 installed inside. Each inner connecting frame 25 has... A movable frame 27 is installed, and each movable frame 27 has a grinding roller 3 installed on its side wall for grinding the hollow cylindrical magnetic core 48. The hollow cylindrical magnetic core 48 is sleeved outside the inner grinding disc 42. The fixing airbag 46 can expand and fix the inner wall of the top of the hollow cylindrical magnetic core 48. Then the main drive motor 35 is started, which drives the transmission rod 36 to rotate. The rotation of the transmission rod 36 drives the hollow cylindrical magnetic core 48 to rotate through the fixing airbag 46. Due to the two... The micro motor 41 remains stationary, so the two inner grinding discs 42 remain stationary. The multiple inner grinding discs 42 grind the inner wall of the hollow cylindrical magnetic core 48. At the same time, the mounting frame 2 starts and drives the grinding rollers 3 to move closer to the hollow cylindrical magnetic core 48. Since the hollow cylindrical magnetic core 48 is rotating, the multiple grinding rollers 3 at the front end of the mounting frame 2 will grind the outer surface of the hollow cylindrical magnetic core 48, thereby achieving simultaneous multi-face grinding and further improving the grinding capability.

[0038] A first fixed frame 11 is fixedly installed on the inner front wall of the grinding equipment body 1. Two first support frames 13 are fixedly installed on the side wall of the first fixed frame 11. The same set of first sliding frames 14 are installed on the surface of the two first support frames 13. A first drive motor 12 is fixedly installed on the side wall of the first fixed frame 11. The lead screw at the end of the first drive motor 12 is threadedly connected to the inside of the first sliding frame 14. In use, since different hollow cylindrical magnetic cores 48 are of different sizes, the first drive motor 12 on the inner wall of the first fixed frame 11 can be started. The operation of the first drive motor 12 drives the first sliding frame 14 to move through the threaded rod. The two sides of the first sliding frame 14 slide outside the two first support frames 13. The movement of the first sliding frame 14 can stably drive the horizontal drive frame 15 and the mounting frame 2 above to move, thereby achieving grinding of hollow cylindrical magnetic cores 48 of different sizes, further improving the adaptability to hollow cylindrical magnetic cores 48 of different sizes. A horizontal drive frame 15 is fixedly installed on the top of the first sliding frame 14. Both ends of the horizontal drive frame 15 are equipped with wheel drive frames 19. A drive belt 17 is fixedly installed between two drive belts 19. A horizontal moving frame 18 is fixedly installed above the drive belt 17, and the drive belt 17 is used to drive the horizontal moving frame 18 to move horizontally. A mounting frame 2 is fixedly installed above the horizontal moving frame 18. A mounting groove 22 is opened on the side wall of the mounting frame 2 near the hollow cylindrical magnetic core 48. Each outer connecting frame 23 is installed in the mounting groove 22. At least two locking bolts 21 for fixing the outer connecting frames 23 are installed on the top of the mounting frame 2. Between the mounting frame 2 and the first sliding frame 14 When the horizontal drive frame 15 is in operation, the motor 16 drives the belt drive frame 19 to rotate. The rotation of the belt drive frame 19 drives the drive belt 17 to move. The movement of the drive belt 17 drives the top horizontal moving frame 18 to move left and right. The movement of the horizontal moving frame 18 drives the mounting frame 2 to move left and right. The movement of the mounting frame 2 drives the three grinding rollers 3 at the end to move horizontally. The horizontal movement of the grinding rollers 3 can perform multiple grindings on the hollow cylindrical magnetic core 48, thereby achieving different types of grinding capabilities and improving the coarseness of a single grinding.

[0039] Two baffles 24 are fixedly installed on the upper and lower surfaces of each outer connecting frame 23. The baffles 24 are used to restrict the movement of the inner connecting frame 25 and the moving frame 27. A first spring 28 is fixedly installed between the back of the moving frame 27 and the inner wall of the inner connecting frame 25. Two second drive motors 26 are fixedly installed on the back of each inner connecting frame 25. When the hollow cylindrical magnetic core 48 rotates and contacts the grinding roller 3, the grinding roller 3 will react to grind the surface of the hollow cylindrical magnetic core 48. There is a first spring 28 between the moving frame 27 on the back of each grinding roller 3 and the inner wall of the inner connecting frame 25. Therefore, when hollow cylindrical magnetic cores 48 of different sizes contact the grinding roller 3, the grinding roller 3 will adaptively adjust the contact force, thereby improving the grinding precision. The lead screw at the end of each second drive motor 26 is threadedly connected to the outer connecting frame 23 and moves through the inner wall of the mounting frame 2. The top of each moving frame 27 Each grinding roller 3 is fixedly mounted with a bracket 29, and the top of each grinding roller 3 is connected to the bracket 29 by a thread. Since different hollow cylindrical magnetic cores 48 require different grinding forces, during grinding, the second drive motor 26 behind each grinding roller 3 is started. The start of the second drive motor 26 can drive the grinding roller 3 to move forward or backward through the first spring 28, thereby adjusting the distance of the grinding roller 3 and increasing or decreasing the pressure of the grinding roller 3 on the hollow cylindrical magnetic core 48. This can meet the grinding requirements of different grinding rollers 3. For example, when the first grinding roller 3 needs to be coarsely ground, the inner connecting frame 25 drives the grinding roller 3 to fit more tightly with the hollow cylindrical magnetic core 48, thereby increasing the grinding force. When the second or third grinding roller 3 is used for fine grinding, the inner connecting frame 25 drives the grinding roller 3 to fit more loosely with the hollow cylindrical magnetic core 48, thereby allowing for light grinding.

[0040] A second fixed frame 31 is fixedly installed on the inner rear wall of the grinding equipment body 1. Two second support frames 32 are fixedly installed below the second fixed frame 31. Second sliding frames 34 are fixedly installed on the side walls of the two second support frames 32. A third drive motor 33 is fixedly installed below the second fixed frame 31. The lead screw at the end of the third drive motor 33 is threadedly connected to the second sliding frame 34. In use, the third drive motor 33 starts and drives the second sliding frame 34 to move. The second sliding frame 34 slides outside the two second support frames 32. The movement of the second sliding frame 34 drives the main drive motor 35 to move. The movement of the main drive motor 35 drives the top hollow cylindrical magnetic core 48 to move. The hollow cylindrical magnetic core 48 can move up or down to fully contact the multiple grinding rollers 3, thereby increasing the grinding range of the grinding rollers 3 on the surface of the hollow cylindrical magnetic core 48 and further improving the overall grinding capacity. The fixed chassis 37 is fixed. The inner slide has two inner slides 38, and the fixed base 37 has two inner slide rods 39 that pass through the inner slides 38. Two second springs 4 are fixed between the two inner slides 38. Each micro motor 41 is fixed on the inner slide 38. The two inner slides 38 can move inside the fixed base 37. Therefore, when installing the hollow cylindrical magnetic core 48, the two inner grinding discs 42 are pushed close to each other. Then the hollow cylindrical magnetic core 48 is sleeved on the two inner grinding discs 42. Then the second springs 4 between the two inner slides 38 drive the inner grinding discs 42 on both sides to fit against the inner wall of the hollow cylindrical magnetic core 48 through the elastic force. Both inner slides 38 can slide outside the inner slide rods 39. By designing the inner grinding discs 42 on both sides to be adjustable in distance, hollow cylindrical magnetic cores 48 with different inner diameters can be ground, further improving the grinding of different types of hollow cylindrical magnetic cores 48.During polishing, two micro motors 41 are activated, driving the inner polishing discs 42 on both sides to move upward or downward. The upward or downward movement of multiple inner polishing discs 42 allows for polishing of the interior of the hollow cylindrical magnetic core 48. Each side has two inner polishing discs 42, and different types can be installed on each side to achieve various levels of fineness. Upper support frames 43 are fitted around the transmission rod 36 and the two micro motors 41. Two support slide rods 45, extending through the fixed base 37, are fixedly installed below the upper support frame 43. Two third springs 44, fitted around the support slide rods 45, are fixedly installed between the upper support frame 43 and the fixed base 37. An inflator 47 is fixedly installed at the top of the transmission rod 36, and a fixed airbag 46 is fixedly fitted onto the surface of the transmission rod 36 near the top and inflated. The inflator 47 and the fixed airbag 46 are connected by an air tube. During installation of the hollow cylindrical magnetic core 48, the inside of the top of the hollow cylindrical magnetic core 48 contacts the fixed airbag 46. Subsequently, the inflator 47 inflates the fixed airbag 46, causing it to expand and fit tightly against the inner wall of the hollow cylindrical magnetic core 48. At this time, the rotation of the transmission rod 36 can drive the hollow cylindrical magnetic core 48 to rotate through the fixed airbag 46. By using the inflatable fixed airbag 46 to fix the hollow cylindrical magnetic core 48, it can accommodate hollow cylindrical magnetic cores 48 of different sizes, improving the connection capability. Since different hollow cylindrical magnetic cores 48 have different heights, the upper support frame 43 can provide better bottom support for the hollow cylindrical magnetic core 48. When encountering a shorter hollow cylindrical magnetic core 48, the third spring 44 below the upper support frame 43 can provide adaptive support.

Many modifications and variations will be apparent to those skilled in the art.
