Description

Technical Field

[0001] This application relates to the technical field of magnetic coupling, and particularly relates to a magnetic coupling device. Background Art

[0002] As a key device that utilizes magnetic field interaction to achieve energy transfer or signal transmission, magnetic coupling devices are widely used in many fields. Their core working mechanism is to achieve effective energy transfer between components through the magnetic force coupling between magnetic components such as inner rotors and outer rotors.

[0003] In actual technical solutions, such as the magnetic coupling device disclosed in the Chinese patent with the publication number "CN209134275U", an outer rotor and an inner rotor are used in cooperation. A first magnet is provided on the inner wall of the outer rotor, a second magnet is provided on the outer wall of the inner rotor, and an isolation sleeve is provided between the outer rotor and the inner rotor. At the same time, by opening grooves on the rotor wall and using the first bushing and the second bushing to assist in fixing the magnet, the reliability and stability of magnet fixation are improved to a certain extent. Moreover, after assembly, there is no need to wait for the glue to cure, shortening the production cycle and improving production efficiency; However, there are obvious deficiencies in the installation and maintenance of existing magnetic coupling devices. For example, the Chinese patent with the patent number "CN201821800818.1" discloses a magnetic coupling device. Both its outer rotor and inner rotor are rotatably connected to the inner side of the housing. The outer magnet is installed on the inner side of the outer rotor, and the inner magnet is installed on the outer side of the inner rotor. In terms of the installation method, it mostly relies on the cooperation of bushings and welding and the assistance of screws. Although welding can ensure a certain stability, the formed integral design makes subsequent disassembly, installation, maintenance, and repair extremely inconvenient; when using screws for installation, not only special screwdrivers are required for disassembly and assembly, but also thread slipping problems are likely to occur due to rust during long-term use. This makes the operation cumbersome both in the early assembly and in the later maintenance, greatly restricting the convenience and practicality of magnetic coupling devices. Therefore, there is an urgent need to innovate and improve the installation and maintenance methods of existing magnetic coupling devices to enhance their overall performance and application value.

Detailed implementation manners

[0018] The following further elaborates on this application Figure 1-8 in conjunction with the attached drawings.

[0019] An embodiment of this application discloses a magnetic coupling device. As Figure 1-8 shown, it includes a housing 1. A chassis 9 is provided at the bottom of the housing 1. A circular groove 2 is formed in the middle of the chassis 9. A turntable 4 is movably connected inside the circular groove 2. A limiting mechanism 3 is fixedly installed at the bottom of the turntable 4. The chassis 9 and the turntable 4 are installed at the bottom of the housing 1 through the limiting mechanism 3. An outer rotor mechanism 5 is rotatably connected to the top of the chassis 9. An inner rotor mechanism 6 is rotatably connected to the top of the turntable 4. The inner cross-sectional shape of the circular groove 2 is arranged in a stepped shape; The limiting mechanism 3 includes a fixed disk 31 and a clamping frame 32. The clamping frames 32 are arranged in an equidistant circular array and fixedly connected to the lower end of the outer side of the housing 1. The fixed disk 31 is fixedly installed at the bottom of the turntable 4. Limiting components 33 are fixedly connected to the outer side of the fixed disk 31 in an equidistant circular array. The ends of the limiting components 33 are inserted into the interior of the clamping frames 32. An adjusting component 34 is movably installed at the bottom of the fixed disk 31. By placing the chassis 9 at the bottom of the housing 1, the circular groove 2 with a stepped cross-section in the middle of the chassis 9 provides a stable and movable installation space for the turntable 4, ensuring that the turntable 4 can rotate smoothly within the circular groove 2. Then, operate the adjusting component 34 at the bottom of the fixed disk 31. The action of the adjusting component 34 will cause corresponding displacements of the limiting components 33 arranged in an equidistant circular array on the outer side of the fixed disk 31. Under the action of the adjusting component 34, the ends of the limiting components 33 gradually insert into the interior of the clamping frames 32 arranged in an equidistant circular array at the lower end of the outer side of the housing 1. When the ends of the limiting components 33 are precisely matched with the clamping frames 32 and are completely inserted, the effect of stably installing the chassis 9 and the turntable 4 on the bottom of the housing 1 through the limiting mechanism 3 is achieved. At this time, the outer rotor mechanism 5 can rotate around its central axis on the top of the chassis 9, and the inner rotor mechanism 6 on the top of the turntable 4 can also rotate around its own center. During the operation of the device, the inner rotor mechanism 6 and the outer rotor mechanism 5 achieve energy transfer or other related magnetic coupling functions through the interaction of magnetic fields. When it is necessary to disassemble, repair, or maintain the device, operate the adjusting component 34 at the bottom of the fixed disk 31 again to make the adjusting component 34 act in the reverse direction, driving the ends of the limiting components 33 to disengage from the interior of the clamping frames 32, releasing the limiting connection, and then the chassis 9 and the turntable 4 can be separated from the bottom of the housing 1, facilitating subsequent detailed inspections, repairs, replacements, etc. of the components inside the device.

[0020] Please refer to Figures 4-6The outer rotor mechanism 5 includes an outer slip ring 51, which is rotatably connected to the top of the chassis 9 and is located on the outside of the inner rotor mechanism 6. An outer rotor body 52 is fixedly installed on the top of the outer slip ring 51. Outer slide grooves 53 are arranged in an annular shape at equal intervals on the outer rotor body 52. ​​The inner sides of the outer slide grooves 53 are slidably connected with outer slide bars 54. An outer clamping assembly 56 is provided on the outer side of the top of the outer slip ring 51. The outer clamping assembly 56 is clamped with the outer slide bar 54. The inner side of the outer slide bar 54 is fixedly connected with an outer magnet 55. The outer clamping assembly 56 includes an outer annular groove 565 and an outer limiting ring 561. The outer annular groove 565 is opened at the top of the outer slip ring 51. The inner side of the outer annular groove 565 is fixedly connected with an outer torsion spring 562. The top of the outer torsion spring 562 An outer rotating ring 563 is fixedly connected, and an outer limiting frame 564 is fixedly connected to the top of the outer rotating ring 563 at equal intervals. The outer limiting ring 561 is fixedly connected to the outer lower end of the outer sliding bar 54 at equal intervals. The outer limiting frame 564 is arranged in an arc shape as a whole, and the end of the outer limiting frame 564 is inserted into the inner part of the outer limiting ring 561. The inner sides of the outer limiting frame 564 and the outer limiting block are arranged in an arc shape. The inner sides of the outer limiting frame 564 and the outer limiting block are arranged concentrically with the outer torsion spring 562. The outer sliding ring 51 is rotatably connected to the top of the chassis 9 and surrounds the outer side of the inner rotor mechanism 6. The outer sliding grooves 53 are arranged in an annular shape at equal intervals on the outer rotor body 52 fixed at the top. When installing the outer magnet 55, first move the outer rotating ring 563, and the outer rotating ring 5 63 rotates under the action of the outer torsion spring 562 located in the outer annular groove 565, driving the outer limit frame 564 connected thereto to rotate synchronously, so that the outer limit frame 564 is misaligned with the outer limit ring 561 at the lower end of the outer side of the outer slide bar 54. At this time, the outer torsion spring 562 is compressed. Then, the outer slide bar 54 is smoothly inserted into the outer slide groove 53 through the sliding cooperation between the outer slider and the outer slide groove 53. Then, the outer rotating ring 563 is loosened, and the outer torsion spring 562 is reset due to elastic potential energy, driving the outer rotating ring 563 to rotate in the opposite direction. The outer rotating ring 563 then pushes the outer limit frame 564 to move, so that the end of the outer limit frame 564 is accurately inserted into the outer limit ring 561. Since the inner sides of the outer limit frame 564 and the outer limit ring 561 are both arc-shaped and aligned with the outer torsion spring 562 is arranged in concentric circles. This structural design makes the outer limit frame 564 and the outer limit ring 561 tightly engaged, thereby realizing the synchronous and stable engagement of all the outer slide strips 54, and then the outer magnet 55 fixedly connected to the inner side of the outer slide strip 54 is stably installed on the outer rotor body 52. ​​When the outer magnet 55 needs to be removed, the outer rotating ring 563 is turned again, and the outer rotating ring 563 drives the outer limit frame 564 to rotate, so that the outer limit frame 564 is separated from the inner side of the outer limit ring 561, and the outer slide strip 54 loses its limit. At this time, the outer slide strip 54 can be pulled out of the outer slide groove 53 through the sliding connection between the outer slider and the outer slide groove 53, completing the removal operation of the outer magnet 55. The whole process realizes convenient and stable installation and disassembly of the outer magnet 55.

[0021] Please refer to Figures 1-3, on the outer upper end of the housing 1, mounting plates 7 are equally spaced, and mounting holes 8 are provided on each mounting plate 7. The mounting holes 8 are countersunk holes. When installing this magnetic coupling device, the design of the countersunk holes allows the heads of the matching screws or bolts to sink into the holes, keeping flush with or slightly lower than the surface of the mounting plate 7. By passing the screws or bolts through the mounting holes 8 and then cooperating with nuts or other fixing components, this device can be connected and fixed to other equipment or structural components. Due to the presence of the countersunk holes, the connected surface is relatively flat. On the one hand, it can avoid situations such as collisions and abrasions that may be caused by the protrusion of the heads of screws or bolts, improving the safety and durability of the device; on the other hand, the flat surface is also more convenient for subsequent protective treatments, such as applying anti-rust paint and installing protective covers, which helps protect the device from the erosion of the external environment and extends the service life of the device.

[0022] Please refer to Figures 1-4, the limiting component 33 includes side rails 331. The side rails 331 are arranged in an equidistant circular pattern and fixedly connected to the outside of the fixed disk 31. A limiting spring 332 is fixedly connected inside the side rail 331. The end of the limiting spring 332 is fixedly connected to a limiting arm 333. The outer end of the limiting arm 333 is fixedly connected to a clamping block 334. The end of the clamping block 334 is inserted into the inside of the clamping frame 32. The adjusting component 34 includes an adjusting disk 344 and a first guide block 341. The adjusting disk 344 is rotatably connected to the bottom of the fixed disk 31. The first guide block 341 is fixedly installed at the bottom of the limiting arm 333. Second guide blocks 342 are fixedly connected to the outside of the adjusting disk 344 at equal intervals. The first guide block 341 and the second guide blocks 342 are in transmission connection. The inner end of the first guide block 341 and the second guide blocks 342 are both arranged as isosceles triangles. The inclined surfaces of the first guide block 341 and the second guide blocks 342 correspond to each other. An adjusting handle 343 is fixedly connected to the bottom of the fixed disk 31. The limiting component 33 and the adjusting component 34 of this device work together to achieve the convenient installation and disassembly of the device. When installing the magnetic coupling device, rotate the adjusting handle 343 to drive the adjusting disk 344 to rotate at the bottom of the fixed disk 31. During the rotation of the adjusting disk 344, the second guide blocks 342 fixedly connected to its outside at equal intervals rotate accordingly. Since the first guide block 341 is fixed to the bottom of the limiting arm 333, and both the first guide block 341 and the second guide blocks 342 are isosceles triangles with their inclined surfaces corresponding to each other. When the second guide block 342 rotates to contact the inclined surface of the first guide block 341, due to the guiding effect of the inclined surface, the second guide block 342 presses the first guide block 341, causing the first guide block 341 to drive the limiting arm 333 to move outward along the side rail 331 against the elastic force of the limiting spring 332, and the limiting spring 332 is stretched. At this time, the clamping block 334 at the outer end of the limiting arm 333 is separated from the clamping frame 32. The chassis 9 and the turntable 4 can be placed at appropriate positions at the bottom of the outer shell 1. Subsequently, rotate the adjusting handle 343 in the reverse direction. The adjusting disk 344 rotates in reverse. The second guide block 342 no longer presses the first guide block 341. The limiting spring 332 resets and pushes the limiting arm 333 to move inward along the side rail 331. The clamping block 334 is inserted back into the inside of the clamping frame 32, realizing the stable installation of the chassis 9 and the turntable 4 at the bottom of the outer shell 1 through the limiting mechanism 3. When disassembly is required, rotate the adjusting handle 343 again and repeat the action of the adjusting disk 344 and the second guide block 342 pressing the first guide block 341, so that the clamping block 334 is separated from the clamping frame 32, and the chassis 9 and the turntable 4 can be separated from the bottom of the outer shell 1 to complete the disassembly operation. The entire process greatly improves the convenience of device installation and disassembly through a clever mechanical structure design.

[0023] Please refer to Figures 5-7, the inner rotor mechanism 6 includes an inner slip ring 61. The inner slip ring 61 is rotatably connected to the top of the turntable 4. The top of the inner slip ring 61 is fixedly installed with an inner rotor body 62. Inner sliding grooves 63 are arranged in an annular pattern at equal intervals on the inner rotor body 62. An inner sliding strip 64 is slidably connected inside the inner sliding groove 63. An inner magnet 65 is fixedly connected to the outer side of the inner sliding strip 64. An inner clamping assembly 66 is installed on the top of the inner slip ring 61 and inside the inner rotor body 62. The inner clamping assembly 66 includes an inner annular groove 661 and an inner limiting ring 662. The inner annular groove 661 is opened on the top of the inner slip ring 61 and inside the inner rotor body 62. An inner torsion spring 663 is fixedly connected inside the inner annular groove 661. The top of the inner torsion spring 663 is fixedly connected to an inner rotating ring 664. The inner limiting ring 662 is fixedly connected to the inner lower end of the inner sliding strip 64. Inner limiting frames 665 are fixedly connected to the bottom of the inner rotating ring 664 in an annular pattern at equal intervals. The ends of the inner limiting frames 665 are inserted into the inner limiting ring 662. The inner sides of the inner limiting frames 665 and the inner limiting blocks are both arc-shaped. The inner sides of the inner limiting frames 665 and the inner limiting blocks and the inner torsion spring 663 are concentrically arranged. The overall cross-sectional shape of the outer sliding strip 54 is set as a cross, and the overall cross-sectional shape inside the outer sliding groove 53 is also set as a cross shape. The outer magnet 55 is integrally arc-shaped, and the inner magnet 65 is also arc-shaped. The overall cross-sectional shape of the inner sliding strip 64 and the inner sliding groove 63 is also set as a cross shape. Both the outer magnet 55 and the inner magnet 65 are set as permanent magnets. When the inner rotor mechanism 6 of this device works, the inner slip ring 61 is used to achieve the rotational connection with the top of the turntable 4, thereby ensuring that the inner rotor body 62 can rotate flexibly. When installing the inner magnet 65, the inner rotating ring 664 is toggled. The inner rotating ring 664 drives the inner limiting frames 665 arranged in an annular pattern at equal intervals on the top to rotate together. Since the inner rotating ring 664 is connected to the inner torsion spring 663 in the inner annular groove 661, the inner torsion spring 663 is compressed during the rotation process, and the inner limiting frames 665 are misaligned with the inner limiting ring 662 at the inner lower end of the inner sliding strip 64. At this time, the inner sliding strip 64 with the inner magnet 65, relying on its cross-sectional shape that is the same as that of the inner sliding groove 63, is smoothly inserted into the inner sliding groove 63 through sliding fit. After the insertion is completed, the inner rotating ring 664 is released. The inner torsion spring 663 returns due to elastic potential energy, driving the inner rotating ring 664 to rotate in the reverse direction. The inner rotating ring 664 pushes the inner limiting frames 665 to move, so that the ends of the inner limiting frames 665 are accurately inserted into the inner limiting ring 662. Since the inner sides of the inner limiting frames 665 and the inner limiting ring 662 are both arc-shaped and concentric with the inner torsion spring 663, this structure can make the inner limiting frames 665 and the inner limiting ring 662 be tightly clamped, thereby stably installing the inner sliding strip 64 on the inner rotor body 62 and realizing the stable installation of the inner magnet 65. When the inner magnet 65 needs to be disassembled, the inner rotating ring 664 is toggled again. The inner limiting frames 665 are separated from the inner limiting ring 662, and the inner sliding strip 64 loses its limit, and the inner sliding strip 64 can be pulled out of the inner sliding groove 63. The outer sliding strip 54 and the outer sliding groove 53 also have a cross-shaped cross-section.The outer magnet 55 is arc-shaped, similar to the inner magnet 65, and both are permanent magnets. When working, the inner and outer magnets 55 use the magnetic field interaction to achieve energy transfer or other magnetic coupling functions between the inner rotor mechanism 6 and the outer rotor mechanism 5. The design of the entire inner rotor mechanism 6 realizes convenient and stable installation and removal of the inner magnet 65, as well as efficient magnetic coupling operation.

[0024] The implementation principle of a magnetic coupling device in an embodiment of the present application is as follows: in the design of the magnetic coupling device, the convenience of installation and disassembly of the device is significantly improved by carefully setting the limiting mechanism 3. During the installation of the device, the inner rotor mechanism 6 is first accurately inserted into the inner side of the outer rotor mechanism 5, and then the two are inserted into the outer shell 1 together. At the same time, the chassis 9 covers the bottom of the outer shell 1. In this process, the first guide block 341 and the second guide block 342 are driven to link by adjusting the twisting adjustment armrest. Since the inclined surfaces of the first guide block 341 and the second guide block 342 are mutually guided and transmitted, the second guide block 342 is squeezed and pushes the limiting arm 333 to move outward. In this process, the limiting spring 332 is pulled to an extended state. At this time, the chassis 9 can smoothly cover the bottom of the outer shell 1, and play a limiting role on the outer rotor mechanism 5, while the inner rotor mechanism 6 is fixed by the limiting mechanism 3. The locking cam 334 is pressed against the locking cam 336 to lock the locking cam 336, and the locking cam 336 is pressed against the locking cam 336, so that the locking cam 336 can be locked. The design of the outer rotor mechanism 5 also facilitates the installation and maintenance of the device. When installing the outer rotor mechanism 5, the outer rotating ring 563 is toggled to rotate. At this time, the outer limiting frame 564 is misaligned with the outer limiting ring 561, and the outer torsion spring 562 is compressed in the outer annular groove 565 it is located in. Subsequently, the outer slider is inserted into the outer sliding groove 53. By utilizing the sliding fit between the outer slider and the outer sliding groove 53, the insertion operation of the outer slider is completed. After releasing the outer rotating ring 563, the outer torsion spring 562 resets, driving the outer rotating ring 563 to rotate. The outer rotating ring 563 pushes the outer limiting frame 564 to move, enabling it to be inserted into the inner part of the outer limiting ring 561. Through the mutual insertion and sleeving of the outer limiting ring 561 and the outer limiting frame 564, the synchronous clamping installation of all the outer sliding strips 54 is achieved, thereby firmly installing the outer magnet 55 on the outer rotor body 52. When it is necessary to disassemble the outer magnet 55, the outer rotating ring 563 is adjusted and twisted to drive each outer limiting frame 564 to disengage from the inner side of the outer limiting ring 561, causing the outer limiting frame 564 and the outer limiting ring 561 to separate from each other. Furthermore, the outer sliding strip 54 can be withdrawn from the outer sliding groove 53, facilitating the rapid replacement of the outer magnet 55. If it is necessary to replace and overhaul the inner rotor mechanism 6, first, the limiting mechanism 3 is removed, and the inner rotor mechanism 6 is withdrawn from the inside of the outer rotor mechanism 5. Then, the inner rotating ring 664 is toggled to rotate, making the inner limiting frame 665 misaligned with the inner limiting ring 662. The inner slider is inserted into the inner sliding groove 63. By means of the sliding fit between the inner slider and the inner sliding groove 63, the insertion operation is completed. During the process of adjusting the inner rotating ring 664, the inner rotating ring 664 squeezes the torsion spring, putting it in a compressed state. After the installation is completed, the inner rotating ring 664 is released, and the inner torsion spring 663 resets to drive the inner rotating ring 664 to rotate, pushing the inner limiting frame 665 to move, enabling it to be inserted into the inner part of the inner limiting ring 662. Through the limiting effect of the inner limiting ring 662 and the inner limiting frame 665, the installation of all the inner sliding strips 64 and the inner magnets 65 on their inner sides is quickly completed. When disassembling, the inner rotating ring 664 is adjusted and twisted in the reverse direction to rotate, driving each inner limiting frame 665 to disengage from the inner side of the inner limiting ring 662. After the inner limiting frame 665 and the inner limiting ring 662 are separated, the inner sliding strip 64 loses its limit and can be quickly withdrawn from the inner sliding groove 63, enabling the device to conveniently replace the inner magnet 65 and the outer magnet 55, further enhancing the overall usability.

Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
