Description

Technical Field

[0001] The present invention belongs to the technical field of grinding equipment. More specifically, it particularly relates to a multi-surface processing equipment for a hollow cylindrical magnetic core. Background Art

[0002] In the field of grinding hollow cylindrical magnetic cores, there are a series of problems to be solved urgently in the current technical means, which seriously limit the grinding efficiency, quality, and equipment versatility.

[0003] First of all, traditional grinding equipment often has difficulty in achieving synchronous multi-surface grinding. Most equipment can only grind a single surface of the hollow cylindrical magnetic core. If it is necessary to grind the inner and outer surfaces simultaneously, multiple clamping and operations are required, which not only consumes a lot of time, but also multiple clamping is likely to cause the position deviation of the magnetic core, affecting the grinding accuracy and resulting in low overall grinding processing ability.

[0004] The adaptability of the equipment to hollow cylindrical magnetic cores of different sizes is poor. Existing grinding equipment is usually designed for magnetic cores of specific sizes. For hollow cylindrical magnetic cores of different sizes, there is a lack of an effective adaptive adjustment mechanism. Operators need to manually replace the appropriate fixtures or adjust the equipment parameters, which is complex and time-consuming, and cannot meet the diverse production requirements.

[0005] The diversity of grinding capabilities is insufficient. The grinding methods of traditional equipment are relatively single, and it is difficult to meet different types of grinding requirements. Whether it is the fineness of grinding or the change of grinding methods, it is restricted by the equipment structure and function, and it is impossible to flexibly handle the grinding tasks of hollow cylindrical magnetic cores with different process requirements.

[0006] It is difficult to guarantee the grinding fineness. During the grinding process, traditional equipment cannot adaptively adjust the grinding contact force according to the surface characteristics of the magnetic core and actual requirements. This may lead to uneven grinding force, resulting in over-grinding or under-grinding in some areas, seriously affecting the grinding quality and accuracy of the hollow cylindrical magnetic core.

[0007] It is difficult to meet the requirements for different grinding forces. Different hollow cylindrical magnetic cores may require different grinding forces during the grinding process. For example, the force requirements for rough grinding and fine grinding are quite different. However, existing equipment often lacks an effective grinding force adjustment mechanism, and it is difficult for operators to precisely control the pressure between the grinding roller and the magnetic core, affecting the grinding effect and product quality.

[0008] Limited grinding range is also one of the common problems. When traditional grinding equipment grinds the surface of a hollow cylindrical magnetic core, it cannot fully cover the entire surface, resulting in some areas not being ground properly, requiring manual secondary processing, reducing the production efficiency, and it is also difficult to ensure the consistency of grinding quality.

[0009] In addition, for hollow cylindrical magnetic cores with different inner diameters, traditional equipment lacks the corresponding inner diameter self-adaptive grinding ability. The grinding components with fixed sizes cannot meet the grinding requirements of magnetic cores with different inner diameters, restricting the versatility and application scope of the equipment.

[0010] In terms of the fixation and support of hollow cylindrical magnetic cores, there are also defects in traditional methods. The commonly used fixation methods are difficult to adapt to hollow cylindrical magnetic cores of different sizes and heights. Loose fixation easily causes the magnetic core to displace during the grinding process, affecting the grinding accuracy. At the same time, there is a lack of self-adaptive bottom support ability for magnetic cores of different heights, further reducing the applicability of the equipment.

[0011] In summary, the existing grinding technologies for hollow cylindrical magnetic cores have significant deficiencies in aspects such as synchronous multi-surface grinding, self-adaptation to magnetic cores of different sizes, diversity of grinding capabilities, grinding fineness, adjustment of grinding force, grinding range, inner diameter self-adaptive grinding, and fixation and support of magnetic cores, and cannot meet the requirements of modern manufacturing for efficient, high-precision, and diversified grinding of hollow cylindrical magnetic cores. Summary of the Invention

[0012] To solve the above technical problems, the present invention provides a multi-surface processing equipment for hollow cylindrical magnetic cores to solve the above problems.

[0013] A multi-surface processing equipment for hollow cylindrical magnetic cores includes a grinding equipment body and a hollow cylindrical magnetic core. A horizontally movable mounting frame is installed inside the grinding equipment body near the front side. At least two groups of outer connection frames are installed inside the mounting frame. An inner connection frame is installed inside each group of outer connection frames. A movable frame is installed inside each inner connection frame. A grinding roller for grinding the hollow cylindrical magnetic core is installed on the side wall of each movable frame. A main driving machine that can move up and down is installed inside the grinding equipment body near the rear side. A transmission rod is fixedly installed at the end of the output shaft of the main driving machine. A fixed chassis is fixedly installed on the top of the main driving machine. The transmission rod rotates through the outside of the fixed chassis. Two micro-motors are arranged on the surface of the fixed chassis. Two inner grinding pieces are installed outside the lead screw at the end of each micro-motor. The hollow cylindrical magnetic core is sleeved outside the inner grinding pieces.

[0014] Preferably, a first fixing frame is fixedly installed on the front inner wall of the grinding equipment body. Two first support frames are fixedly installed on the side wall of the first fixing frame. The same group of first sliding frames are installed on the surfaces of the two first support frames. A first driving motor is fixedly installed on the side wall of the first fixing frame. The lead screw at the end of the first driving motor is in threaded connection with the inside of the first sliding frame. A horizontal driving frame is fixedly installed on the top of the first sliding frame. Belt driving frames are installed at both ends of the horizontal driving frame. A driving belt is fixedly installed between the two belt driving frames. A horizontal moving frame is fixedly installed above the driving belt, and the driving belt is used to drive the horizontal moving frame to move horizontally. The mounting frame is fixedly installed above the horizontal moving frame. Mounting grooves are formed in the side walls of the mounting frame near the hollow cylindrical magnetic core. Each outer connection frame is installed in the mounting groove. At least two locking bolts for fixing the outer connection frame are installed above the mounting frame.

[0015] Preferably, two baffles are fixedly installed on the upper and lower surfaces of each outer connection frame. The baffles are used to limit the movement of the inner connection frame and the moving frame. A first spring is fixedly installed between the back surface of the moving frame and the inner wall of the inner connection frame. Two second driving motors are fixedly installed on the back surface of each inner connection frame. The lead screws at the ends of the two second driving motors are in threaded connection with the outer connection frame and movably penetrate through the inner wall of the mounting frame. Fixed brackets are fixedly installed on the tops of the moving frames. The tops of the grinding rollers are connected to the fixed brackets by threads.

[0016] Preferably, a second fixing frame is fixedly installed on the rear inner wall of the grinding equipment body. Two second support frames are fixedly installed below the second fixing frame. A second sliding frame is fixedly installed on the side walls of the two second support frames. A third driving motor is fixedly installed below the second fixing frame. The lead screw at the end of the third driving motor is in threaded connection with the second sliding frame. Two inner sliding frames are slidably embedded in the inside of the fixed chassis. Two inner sliding rods penetrating through the inner sliding frames are fixedly installed inside the fixed chassis. Two second springs are fixedly installed between the two inner sliding frames. Each micro motor is fixedly installed on the inner sliding frame. Upper support frames are sleeved outside the transmission rod and the two micro motors. Two support sliding rods penetrating outside the fixed chassis are fixedly installed below the upper support frames. Two third springs sleeved outside the support sliding rods are fixedly installed between the upper support frame and the fixed chassis. An air inflator is fixedly installed on the top of the transmission rod. A fixed airbag is fixedly sleeved on the surface of the transmission rod near the top. The air inflator and the fixed airbag are connected by a trachea.

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

[0018] In the present invention, a hollow cylindrical magnetic core is sleeved outside the inner grinding sheet. The fixed airbag can expand and fix the inner wall of the top of the hollow cylindrical magnetic core. Subsequently, the main drive motor is started. The main drive motor drives the transmission rod to rotate when it starts. The transmission rod rotates and drives the hollow cylindrical magnetic core to rotate through the fixed airbag. Since the two micro motors at the top of the main drive motor do not move, the upper and lower inner grinding sheets remain stationary. Multiple inner grinding sheets grind the inner wall of the hollow cylindrical magnetic core. At the same time, the mounting frame is started to drive the grinding rollers to approach the hollow cylindrical magnetic core. Since the hollow cylindrical magnetic core is rotating, multiple grinding rollers at the front end of the mounting frame will grind the outer surface of the hollow cylindrical magnetic core, so that synchronous multi-surface grinding treatment can be realized, and the grinding treatment ability is further improved.

[0019] In the present invention, during use, since different hollow cylindrical magnetic cores have different sizes, the first drive motor on the inner wall of the first fixing frame can be started. The first drive motor operates to drive 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. When the first sliding frame moves, it can stably drive the upper horizontal drive frame and the mounting frame to move, so that different-sized hollow cylindrical magnetic cores can be ground, and the adaptability to different-sized hollow cylindrical magnetic cores is further improved.

[0020] In the present invention, when the horizontal drive frame between the mounting frame and the first sliding frame is operating, the motor can drive the wheel belt drive frame to rotate. The rotation of the wheel belt drive frame drives the drive belt to move. The movement of the drive belt drives the horizontal moving frame at the top to move left and right. The movement of the horizontal moving frame drives the mounting frame to move left and right. 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 grind the hollow cylindrical magnetic core multiple times, so that different types of grinding capabilities can be realized, and the thickness of one-time grinding can be increased.

[0021] In the present 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 different-sized hollow cylindrical magnetic cores contact the grinding roller, the grinding roller will adaptively adjust the contact force, so that the fineness of grinding can be improved.

[0022] In the present invention, since different hollow cylindrical cores require different grinding forces, during grinding, the second drive motors behind each grinding roller are started. The start of the second drive motors can drive the grinding rollers to move forward or backward through the first springs, thereby adjusting the distance between the grinding rollers, increasing or decreasing the pressure of the grinding rollers on the hollow cylindrical cores, and meeting the requirements of different grinding rollers. For example, when the first grinding roller needs rough grinding, the inner connecting frame drives the grinding roller to fit tightly with the hollow cylindrical core, thereby increasing the grinding force. When the second or third grinding roller performs fine grinding, the inner connecting frame drives the grinding roller to fit loosely with the hollow cylindrical core, thereby performing light grinding.

[0023] In the present invention, during use, the third drive motor is started to drive the second sliding frame to move. The second sliding frame slides outside the two second support frames. The movement of the second sliding frame drives the main drive motor to move, and the movement of the main drive motor drives the top hollow cylindrical core to move. The upward or downward movement of the hollow cylindrical core can fully contact with multiple grinding rollers, thereby increasing the range of the surface grinding of the hollow cylindrical core by the grinding rollers and further improving the overall grinding ability.

[0024] In the present invention, the two inner sliding frames can move inside the fixed chassis. Therefore, when installing the hollow cylindrical core, the two inner grinding pieces are pushed closer to each other. Then, the hollow cylindrical core is sleeved outside the two inner grinding pieces. Subsequently, the second spring between the two inner sliding frames drives the two inner grinding pieces on both sides to fit with the inner wall of the hollow cylindrical core through elasticity. The two inner sliding frames can both slide outside the inner sliding rods. By designing the inner grinding pieces on both sides to be adjustable in distance, different inner diameters of hollow cylindrical cores can be ground, further improving the grinding of different types of hollow cylindrical cores. During grinding, the two micro motors are started. The two micro motors drive the inner grinding pieces on both sides to move upward or downward. The upward or downward movement of multiple inner grinding pieces can grind the inside of the hollow cylindrical core, and there are two inner grinding pieces on each side. The two inner grinding pieces on each side can be installed in different types, thereby achieving multiple levels of fine grinding.

[0025] In the present invention, when the hollow cylindrical core is installed, the inside of the top of the hollow cylindrical core contacts the fixed airbag. Subsequently, the inflator inflates the fixed airbag. The fixed airbag expands and tightly fits with the inner wall of the hollow cylindrical core. At this time, the rotation of the transmission rod can drive the hollow cylindrical core to rotate through the fixed airbag. By using an inflatable fixed airbag to fix the hollow cylindrical core, different sizes of hollow cylindrical cores can be adapted, improving the connection ability. Since different hollow cylindrical cores have different heights, the upper support frame can provide better bottom support for the hollow cylindrical core. When encountering a shorter hollow cylindrical core, the third spring below the upper support frame can provide adaptive support. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0036] The following further describes in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0037] Please refer to Figures 1-9, the present invention provides a multi - surface processing device for a hollow cylindrical magnetic core, including a grinding device body 1 and a hollow cylindrical magnetic core 48. Inside the grinding device body 1 near the rear side, there is a main drive motor 35 that can move up and down. The first drive motor 12, the second drive motor 26, and the third drive motor 33 are all composed of a motor and a threaded rod, and the threaded rod is fixed at the end of the output shaft of the motor. The end of the output shaft of the main drive motor 35 is fixedly installed with a transmission rod 36. The top of the main drive motor 35 is fixedly installed with a fixed chassis 37. The transmission rod 36 rotates through the outside of the fixed chassis 37, and there are two micro - motors 41 arranged on the surface of the fixed chassis 37. Outside the lead screw at the end of each micro - motor 41, there are two inner grinding pieces 42 installed; Inside the grinding device body 1 near the front side, there is an installation frame 2 that can move horizontally. Inside the installation frame 2, there are at least two groups of outer connection frames 23 installed. Inside each group of outer connection frames 23, there is an inner connection frame 25 installed. Inside each inner connection frame 25, there is a moving frame 27 installed. On the side wall of each moving frame 27, there is a grinding roller 3 for grinding the hollow cylindrical magnetic core 48. The hollow cylindrical magnetic core 48 is sleeved outside the inner grinding pieces 42. The fixed airbag 46 can expand and fix the inner wall at the top of the hollow cylindrical magnetic core 48. Then, the main drive motor 35 is started. The main drive motor 35 drives the transmission rod 36 to rotate when it starts. The transmission rod 36 rotates and drives the hollow cylindrical magnetic core 48 to rotate through the fixed airbag 46. Since the two micro - motors 41 at the top of the main drive motor 35 do not move, the upper and lower inner grinding pieces 42 remain stationary, and the multiple inner grinding pieces 42 grind the inner wall of the hollow cylindrical magnetic core 48. At the same time, the installation frame 2 starts to drive the grinding rollers 3 to approach 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 installation frame 2 will grind the outer surface of the hollow cylindrical magnetic core 48. Thus, synchronous multi - surface grinding processing can be achieved, further improving the grinding processing ability.

[0038] A first fixing frame 11 is fixedly installed on the inner wall of the front side of the grinding equipment body 1. Two first support frames 13 are fixedly installed on the side wall of the first fixing frame 11. The surfaces of the two first support frames 13 are provided with the same group of first sliding frames 14. A first driving motor 12 is fixedly installed on the side wall of the first fixing frame 11. The lead screw at the end of the first driving motor 12 is in threaded connection with the inside of the first sliding frame 14. During use, since the sizes of different hollow cylindrical magnetic cores 48 are different, the first driving motor 12 on the inner wall of the first fixing frame 11 can be started. The operation of the first driving 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 upper horizontal driving frame 15 and the mounting frame 2 to move, so as to achieve grinding of different sizes of hollow cylindrical magnetic cores 48, further improving the adaptability to different sizes of hollow cylindrical magnetic cores 48. A horizontal driving frame 15 is fixedly installed on the top of the first sliding frame 14. Belt driving frames 19 are installed at both ends of the horizontal driving frame 15. A driving belt 17 is fixedly installed between the two belt driving frames 19. A horizontal moving frame 18 is fixedly installed above the driving belt 17, and the driving belt 17 is used to drive the horizontal moving frame 18 to move horizontally. The mounting frame 2 is fixedly installed above the horizontal moving frame 18. An installation groove 22 is formed in the side wall of the mounting frame 2 near the hollow cylindrical magnetic core 48. Each outer connection frame 23 is installed in the installation groove 22. At least two locking bolts 21 for fixing the outer connection frame 23 are installed above the mounting frame 2. When the horizontal driving frame 15 between the mounting frame 2 and the first sliding frame 14 is operating, the motor 16 can drive the belt driving frame 19 to rotate. The rotation of the belt driving frame 19 drives the driving belt 17 to move. The movement of the driving belt 17 drives the horizontal moving frame 18 at the top 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, so as to achieve different grinding capabilities and improve the fineness of one-time grinding.

[0039] Two baffles 24 are fixedly installed on the upper and lower surfaces of each outer connection frame 23. The baffles 24 are used to limit the movement of the inner connection frame 25 and the moving frame 27. A first spring 28 is fixedly installed between the back surface of the moving frame 27 and the inner wall of the inner connection frame 25. Two second driving motors 26 are fixedly installed on the back surface of each inner connection frame 25. When the hollow cylindrical core 48 rotates and contacts the grinding roller 3, the grinding roller 3 will react to grind the surface of the hollow cylindrical core 48. There is a first spring 28 between the moving frame 27 on the back surface of each grinding roller 3 and the inner wall of the inner connection frame 25. Therefore, when the hollow cylindrical cores 48 of different sizes contact the grinding roller 3, the grinding roller 3 will adaptively adjust the contact force, so as to improve the fineness of grinding. The lead screws at the ends of each second driving motor 26 are threadedly connected to the outer connection frame 23 and movably penetrate through the inner wall of the mounting frame 2. A fixed bracket 29 is fixedly installed on the top of each moving frame 27. The top of each grinding roller 3 is connected to the fixed bracket 29 by threads. Since different hollow cylindrical cores 48 require different grinding forces, when grinding, the second driving motors 26 behind each grinding roller 3 are started. The start of the second driving motor 26 can drive the grinding roller 3 to move forward or backward through the first spring 28, so as to adjust the distance of the grinding roller 3, so as to increase or decrease the pressure of the grinding roller 3 on the hollow cylindrical core 48, so as to meet the requirements of different grinding rollers 3 for grinding. For example, when the first grinding roller 3 needs rough grinding, the inner connection frame 25 drives the grinding roller 3 to fit tightly with the hollow cylindrical core 48, so as to increase the grinding force. When the second or third grinding roller 3 performs fine grinding, the inner connection frame 25 drives the grinding roller 3 to fit loosely with the hollow cylindrical core 48, so as to perform light grinding.

[0040] A second fixing frame 31 is fixedly installed on the rear inner wall of the grinding equipment body 1. Two second support frames 32 are fixedly installed below the second fixing frame 31. A second sliding frame 34 is fixedly installed on the side walls of the two second support frames 32. A third driving motor 33 is fixedly installed below the second fixing frame 31. The lead screw at the end of the third driving motor 33 is threadedly connected to the second sliding frame 34. During use, the third driving motor 33 starts to drive 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 will drive the main driving machine 35 to move. The movement of the main driving machine 35 will drive the top hollow column core 48 to move. The upward or downward movement of the hollow column core 48 can fully contact with multiple grinding rollers 3, so as to improve the grinding range of the grinding rollers 3 on the surface of the hollow column core 48 and further improve the overall grinding ability. Two inner sliding frames 38 are slidably embedded in the fixed chassis 37. Two inner sliding rods 39 passing through the inner sliding frames 38 are fixedly installed inside the fixed chassis 37. Two second springs 4 are fixedly installed between the two inner sliding frames 38. Each micro motor 41 is respectively fixed on the inner sliding frame 38. The two inner sliding frames 38 can move inside the fixed chassis 37. Therefore, when installing the hollow column core 48, the two inner grinding pieces 42 are pushed towards each other and then the hollow column core 48 is sleeved outside the two inner grinding pieces 42. Subsequently, the second spring 4 between the two inner sliding frames 38 drives the two inner grinding pieces 42 to fit with the inner wall of the hollow column core 48 through elasticity. Both inner sliding frames 38 can slide outside the inner sliding rods 39. By designing the two inner grinding pieces 42 on both sides to be adjustable in distance, the hollow column core 48 with different inner diameters can be ground, and further improve the grinding of different types of hollow column cores 48;When grinding, two micro-motors 41 are started. The two micro-motors 41 drive the inner grinding discs 42 on both sides to move up or down. The upward or downward movement of the multiple inner grinding discs 42 can grind the inside of the hollow cylindrical core 48. And there are two inner grinding discs 42 on each side, and the two inner grinding discs 42 on each side can be installed with different types, so as to achieve grinding with multiple fineness levels. The transmission rod 36 and the two micro-motors 41 are both sleeved with upper support frames 43. And two support slide rods 45 that penetrate outside the fixed chassis 37 are fixedly installed below the upper support frame 43. And two third springs 44 sleeved outside the support slide rods 45 are fixedly installed between the upper support frame 43 and the fixed chassis 37. An air inflator 47 is fixedly installed at the top of the transmission rod 36. A fixed airbag 46 is fixedly sleeved on the surface of the transmission rod 36 near the top. And the air inflator 47 and the fixed airbag 46 are connected by an air pipe. When the hollow cylindrical core 48 is installed, the inside of the top of the hollow cylindrical core 48 contacts the fixed airbag 46. Subsequently, the air inflator 47 inflates the fixed airbag 46, and the fixed airbag 46 expands and tightly fits with the inner wall of the hollow cylindrical core 48. At this time, the rotation of the transmission rod 36 can drive the hollow cylindrical core 48 to rotate through the fixed airbag 46. By using the inflatable fixed airbag 46 to fix the hollow cylindrical core 48, it is possible to adapt to hollow cylindrical cores 48 of different sizes and improve the connection ability; Since the heights of different hollow cylindrical cores 48 are different, the upper support frame 43 can provide good bottom support ability for the hollow cylindrical core 48. When encountering a shorter hollow cylindrical core 48, the third spring 44 below the upper support frame 43 can provide adaptive support ability.;
