Description

Technical Field

[0001] This utility model relates to a multi-point supported mobile base type permanent magnet speed regulator, belonging to the technical field of permanent magnet speed regulators. Background Technology

[0002] Permanent magnet speed regulation is one of the key national energy-saving technology promotion projects. It is a transmission method that is different from traditional transmission and uses magnetic force transmission. The main adjustment method is to adjust the relative position of the cylindrical permanent magnet rotor and the cylindrical conductor rotor in the axial direction to change the effective part of the coupling between the permanent magnet rotor and the conductor rotor, thereby changing the torque transmitted between them. It can achieve repeatable, adjustable and controllable output torque and speed, thereby achieving the purpose of speed regulation and energy saving.

[0003] Adjusting the relative position of the cylindrical permanent magnet rotor and the cylindrical conductor rotor along the axial direction is the core of the permanent magnet speed controller. However, most existing technologies adjust the position of the stator or rotor separately, which has the following problems:

[0004] 1. During individual adjustment, the accuracy is low, and the height of the stator and rotor is prone to change, resulting in the stator and rotor torques being different from the predicted torques.

[0005] 2. The permanent magnet speed controller is fixedly connected to the base as a whole, which makes it impossible to install stators and rotors of different sizes on the base. This results in a low compatibility rate between the base and the permanent magnet speed controller, and a high cost of use.

[0006] 3. When adjusting the position, foreign objects on the base may cause deviations during adjustment, affecting the final accuracy of the permanent magnet speed controller.

[0007] In summary, there is a need for a multi-point supported mobile base type permanent magnet speed controller that can adapt to stators and rotors of different sizes and automatically clean foreign objects from the slide rails.

[0008] Patent application number 202410396129.2: This invention discloses a permanent magnet speed regulator, which relates to the field of permanent magnet speed regulation technology, and in particular to a mobile base type permanent magnet speed regulator, including a mobile plate and a loading plate. A base is provided above the loading plate, and a permanent magnet speed regulator and a main motor are installed above the base. A scissor arm is installed between the top surface of the mobile plate and the bottom surface of the loading plate. A connecting rod is rotatably connected to the right side of the scissor arm. A moving block is fixedly installed at the middle position of the connecting rod. An mounting plate is installed on the top surface of the mobile plate. An auxiliary motor is installed on one side of the mounting plate, and a rotatable first lead screw is connected to one side of the auxiliary motor.

[0009] This application sets up a scissor arm between the moving plate and the loading plate, and the scissor arm can be folded by starting the auxiliary motor. This allows the height of the main motor and the permanent magnet speed controller to be adjusted, so that the device can be applied to machines of different heights. At the same time, it increases the adjustment efficiency, reduces the manpower required for adjustment, and increases the practicality of the device. However, it only adjusts the height of the permanent magnet speed controller and cannot adjust the height of the stator and rotor, so it cannot precisely adjust the torque. Utility Model Content

[0010] The technical problem to be solved by this utility model is that the distance between the stator and the rotor cannot be precisely adjusted, resulting in the torque of the stator and rotor being different from the predicted torque, and stators and rotors of different sizes cannot be installed on the same base.

[0011] To address the aforementioned technical problems, a multi-point supported mobile base type permanent magnet speed controller is proposed; this is achieved through the following technical solution:

[0012] The system includes a stator body, a rotor motor, and a rotor body. It also includes an adjustment base, a cleaning structure, a first mounting structure, a displacement structure, and a protective shell. The adjustment base includes a fixed base, a movable base, and a drive structure. The movable base and the drive structure are mounted on the fixed base. The drive structure drives the movable base to slide on the fixed base to adjust the distance between the stator body and the rotor body. The cleaning structure for cleaning the fixed base is mounted on the side of the fixed base. The rotor motor and the rotor body are mounted on the fixed base through the first mounting structure. The stator body is detachably mounted on the sliding base through the displacement structure. Stator bodies and rotor bodies of different sizes can be adjusted and installed. The stator body and the rotor body are provided with a protective shell of adjustable length.

[0013] The movable seat is driven to slide on the fixed seat by the drive structure, and the distance between the fixed seat and the movable seat is adjusted, thereby precisely adjusting the distance between the stator body and the rotor body. The installation position and height of the rotor are adjusted by the first mounting structure, and the installation height of the stator is adjusted by the displacement structure. This makes the whole device applicable to stators and rotors of different sizes, ensuring that stators and rotors of different sizes can be installed in positions suitable for the use environment. The cleaning structure for cleaning the fixed seat ensures that the movable seat can slide normally on the fixed seat, reducing the impact of foreign objects on the fixed seat on the adjustment process.

[0014] In a preferred embodiment of the present invention, a plurality of sliding grooves are evenly provided on the upper surface of the bottom of the fixed seat. The movable seat includes a slider and a base plate that are adapted to the sliding grooves. One end of the slider is mounted on the base plate, and the other end is slidably mounted inside the sliding groove. One end of the drive structure is mounted on the fixed seat, and the other end passes through the fixed seat and connects to the base plate, thereby driving the base plate and the slider to move. The slider moves inside the sliding groove to adjust the distance between the stator and the rotor.

[0015] In a preferred embodiment of the present invention, the drive structure includes a first motor and a first threaded rod. The first motor is mounted on a fixed base, and the output end of the first motor is connected to the first threaded rod. The first threaded rod passes through the fixed base and connects to the base plate of the movable base. The base plate rotates with the first threaded rod, moving closer to or away from the fixed base. The first motor drives the first threaded rod to rotate, and the base plate is threadedly connected to the first threaded rod. The rotation of the first threaded rod causes the base plate to move closer to or away from the fixed base, thereby adjusting the distance between the stator and the rotor.

[0016] In a preferred embodiment of the present invention, a cleaning structure is connected to the side of the fixed base. The cleaning structure includes a power supply, a connecting plate, an electric telescopic rod, and a scraper. The electric telescopic rod is installed on the side of the fixed base through the connecting plate. One end of the electric telescopic rod passes through the connecting plate and connects to the power supply, while the other end connects to the scraper. The bottom of the scraper is located inside the groove. The electric telescopic rod pulls the scraper to scrape foreign objects inside the groove from the end of the fixed base near the connecting plate.

[0017] In a preferred embodiment of the present invention, a mounting plate is connected to the top of the fixed base, and a plurality of first rhomboid mounting holes are evenly arranged on the mounting plate. A heat dissipation structure is provided below the mounting plate inside the fixed base. The heat dissipation structure includes a partition, a heat dissipation motor and a heat dissipation fan. The partition is installed inside the fixed base, and a heat dissipation fan connected to the heat dissipation motor is provided above the partition. The heat dissipation fan dissipates heat from the rotor motor.

[0018] In a preferred embodiment of the present invention, a buffer spring and a damper are provided between the partition and the mounting plate to reduce the vibration of the rotor motor.

[0019] In a preferred embodiment of the present invention, the rotor motor is connected to the mounting plate via a first mounting structure. The first mounting structure includes a motor base, a positioning pin, and a locking nut. The rotor motor is mounted on the motor base, which has a second rhomboid mounting hole identical to the first rhomboid mounting hole on the mounting plate. The positioning pin passes through the first and second rhomboid mounting holes, and the locking nut is threaded onto the positioning pin in a direction perpendicular to the first and second rhomboid mounting holes, thus fixing the motor base and the mounting plate. The mounting height of the rotor motor is changed by altering the thickness of the motor base, and the position of the motor base is then fixed by the positioning pin and the locking nut.

[0020] In a preferred embodiment of the present invention, the stator body is mounted on the base plate of the sliding seat via a displacement structure. The displacement structure includes two limiting frames, two second motors, two second threaded rods, and a lifting platform. The two limiting frames are respectively mounted on the two sides of the upper surface of the base plate. The second motors are mounted on the top of the limiting frames, and the output ends of the second motors are connected to the second threaded rods. The second threaded rods are installed inside the limiting frames, and the lifting platform is connected to the two second threaded rods. The stator body is detachably mounted on the lifting platform via a second mounting structure. The second mounting structure is identical to the first mounting structure. The height of the stator body is adjusted to ensure that the stator body and the rotor body are at the same height.

[0021] In a preferred embodiment of the present invention, the protective housing includes an upper housing, a lower housing, an extension housing, and fixing bolts. The upper housing is connected to one end of the rotor motor, and a slot is provided inside the upper housing. The end of the lower housing away from the displacement structure is connected to the extension housing. The extension housing is inserted into the slot of the upper housing. Two fixing holes are provided on the upper housing and the extension housing respectively. The fixing bolts pass through the fixing holes to fix the installation distance between the upper housing and the lower housing. The length of the protective housing can be adjusted to adapt to stator bodies and rotor bodies of different sizes and lengths.

[0022] In a preferred embodiment of the present invention, a heat dissipation water tank is provided on the movable seat. The heat dissipation water tank is connected to a spray pipe and a return pipe. The other ends of the spray pipe and the return pipe are connected to the protective shell. Water in the heat dissipation water tank enters the protective shell from the spray pipe and is returned to the heat dissipation water tank from the return pipe. Cooling water inside the heat dissipation water tank enters the protective shell from the spray pipe to dissipate heat from the stator body and the rotor body, and then returns to the heat dissipation water tank from the return pipe.

[0023] The advantages of this utility model compared with the prior art are:

[0024] 1. The movable seat is driven to slide on the fixed seat by the drive structure, and the distance between the fixed seat and the movable seat is adjusted, thereby accurately adjusting the distance between the stator body and the rotor body and reducing the position error during the adjustment process;

[0025] 2. The installation position and height of the rotor are adjusted by the first installation structure, and the installation height of the stator is adjusted by the displacement structure, so that the whole device can be used for stators and rotors of different sizes, ensuring that stators and rotors of different sizes can be installed in positions suitable for the operating environment;

[0026] 3. The cleaning structure used for cleaning the fixed seat ensures that the movable seat can slide normally on the fixed seat, reducing the impact of foreign objects on the fixed seat on the adjustment process. Attached Figure Description

[0038] The following will refer to the appendix in the embodiments of this utility model. Figures 1-10 The technical solutions in the embodiments of this utility model will be described in detail below. Example

[0039] like Figure 1 , 2 3, 4, 5 and Figure 6 As shown, a multi-point supported mobile base type permanent magnet speed controller includes a stator body 1, a rotor motor 2, a rotor body 3, and also includes an adjustment base 4, a cleaning structure 5, a first mounting structure 6, a displacement structure 7, and a protective shell 8. The adjustment base 4 includes a fixed base 41, a movable base 42, and a drive structure 43.

[0040] The adjustment base 4 includes a fixed base 41, a movable base 42, and a drive structure 43. The movable base 42 is slidably mounted on the fixed base 41. One end of the drive structure 43 is fixedly mounted on the side of the fixed base 41, and the other end is connected to the movable base 42, driving the movable base 42 to move horizontally on the fixed base 41.

[0041] The mounting plate 9 is fixed to the top of the fixed base 41 by screws. The mounting plate 9 is connected to the rotor motor 2 through the first mounting structure 6. Changing the thickness of the first mounting structure 6 changes the installation height of the rotor motor 2. The output shaft of the rotor motor 2 is connected to the rotor body 3. Changing the installation height of the rotor motor 2 changes the height of the rotor body 3. Different sizes of rotor motors 2 can be installed at different heights, so that the rotor body 3 can be applied to machines of different heights.

[0042] The first mounting structure 6 connects with the different first diamond-shaped mounting holes 91 on the mounting plate 9 to adjust the horizontal mounting position of the rotor motor 2 and the rotor body 3. This allows for the control of different sizes of rotor motor 2 to be installed in a suitable horizontal position, facilitating the use of different sizes of rotor motor 2 and rotor body 3 with the machine.

[0043] The first mounting structure 6 allows the rotor motor 2 to be detachably connected to the mounting plate 9, and the position of the rotor motor 2 is precise and stable.

[0044] The stator body 1 is detachably connected to the movable base 42 via the displacement structure 7. The displacement structure 7 adjusts the installation height of the stator body 1 on the movable base 42. The height of the stator body 1 is adjusted by the displacement structure 7, which cooperates with the rotor body 3, so that the adjustment base 4 can install stator bodies 1 and rotor bodies 3 of different sizes, which increases the compatibility of the adjustment base 4 with the permanent magnet speed controller and improves the practicality of the whole device.

[0045] The cleaning structure 5 is fixedly installed on the fixed seat 41. The cleaning structure 5 cleans the sliding groove 44 on the fixed seat 41, ensuring that the movement of the movable seat 42 inside the sliding groove 44 is not affected by foreign objects, and ensuring the accuracy of distance adjustment.

[0046] The mounting base 41 is equipped with a heat dissipation structure 10. A buffer spring 11 and a damper are also provided between the heat dissipation structure 10 and the mounting plate 9. The buffer spring 11 and the damper provide buffering force for the rotor motor 2 and improve the stability of the rotor motor 2.

[0047] The stator body 1 and the rotor body 3 are provided with an adjustable length protective shell 8. The adjustable length of the protective shell 8 ensures that stator bodies 1 and rotor bodies 3 of different sizes can be installed inside the protective shell 8.

[0048] A cooling water tank 12 is provided on the movable seat 42. The cooling water tank 12 is connected to a water spray pipe 13 and a water return pipe 14. The other end of the water spray pipe 13 and the water return pipe 14 are connected to the protective shell 8. The cooling water inside the cooling water tank 12 dissipates heat from the stator body 1 and the rotor body 3.

[0049] like Figure 6 As shown, a plurality of sliding grooves 44 are evenly arranged on the upper surface of the fixed seat 41. In this embodiment, four sliding grooves 44 are provided on the fixed seat 41. The movable seat 42 includes a slider 421 and a base plate 422. The slider 421, which is used to cooperate with the sliding grooves 44, is fixedly connected to the middle position of the upper surface of the base plate 422. In this embodiment, four protrusions that are adapted to the sliding grooves 44 are provided on the lower surface of the slider 421. One end of the driving structure 43 is fixedly installed on the side of the fixed seat 41. The other end of the driving structure 43 passes through the fixed seat 41 and is threadedly connected to the movable seat 42. The driving structure 43 rotates to drive the movable seat 42 to move closer to or away from the fixed seat 41.

[0050] The drive structure 43 includes two sets of first motors 431 and first threaded rods 432. The two sets of first motors 431 and first threaded rods 432 are respectively installed at both ends of the side of the fixed base 41. The first motors 431 are installed on the side of the fixed base 41 by screws.

[0051] The fixed base 41 has two holes for the first threaded rod 432 to pass through. One end of the first threaded rod 432 is connected to the first motor 431, and the other end of the first threaded rod 432 is threadedly connected to the base plate 422 of the movable base 42. The first motor 431 drives the first threaded rod 432 to rotate, and the first threaded rod 432 drives the base plate 422 to move closer to or further away from the fixed base 41, thereby controlling the distance between the rotor body 3 installed on the fixed base 41 and the stator body 1 on the movable base 42. The movement of the movable base 42 controlled by the first motor 431 ensures the stability of the displacement of the stator body 1 and prevents displacement in other directions.

[0052] like Figure 6 As shown, a cleaning structure 5 is fixedly connected to the middle position of the side of the fixed base 41 by screws. The cleaning structure 5 includes a power supply 51, a connecting plate 52, an electric telescopic rod 53 and a scraper 54. The connecting plate 52 is welded to the side of the fixed base 41. The electric telescopic rod 53 is fixedly installed in the middle position of the connecting plate 52 by screws. One end of the electric telescopic rod 53 passes through the connecting plate 52 and connects to the power supply 51, and the other end connects to the scraper 54. The bottom of the scraper 54 is set inside the slide groove 44.

[0053] When the adjusting base 4 is not working, the cleaning structure 5 extends until the scraper 54 contacts the movable seat 42. Before the adjusting base 4 needs to work, the cleaning structure 5 is started first, the power supply 51 is turned on, the electric telescopic rod 53 is driven to retract, and the scraper 54 is pulled to move towards the power supply 51 to scrape out foreign objects inside the slide groove 44. This reduces the adjustment deviation caused by foreign objects inside the slide groove 44 during the movement of the movable seat 42, and ensures the stability of the distance adjustment between the rotor body 3 and the stator body 1.

[0054] like Figure 1 As shown, the upper end of the fixing base 41 is fixedly connected to the mounting plate 9 by screws. The mounting plate 9 is evenly provided with a plurality of first diamond-shaped mounting holes 91, and a heat dissipation structure 10 is provided in the middle of the fixing base 41.

[0055] like Figure 5 As shown, the heat dissipation structure 10 includes a partition 101, a heat dissipation motor 102, and a heat dissipation fan 103. The partition 101 is welded inside the fixed base 41. The heat dissipation motor 102 is fixedly installed above the partition 101. The output shaft of the heat dissipation motor 102 is connected to the heat dissipation fan 103. The heat dissipation motor 102 drives the heat dissipation fan 103 to rotate, thereby dissipating heat from the rotor motor 2 installed on the mounting plate 9. The first diamond-shaped mounting hole 91 on the mounting plate 9 facilitates the heat dissipation structure 10 to dissipate heat from the rotor motor 2.

[0056] like Figure 2 and Figure 7 As shown, the mounting plate 9 is connected to the rotor motor 2 through the first mounting structure 6. The first mounting structure 6 includes a motor base 61, a positioning pin 62, and a locking nut 63. The rotor motor 2 is mounted on the motor base 61 by screws. The motor base 61 is provided with a second diamond-shaped mounting hole 64 that cooperates with the first diamond-shaped mounting hole 91. The bottoms of the first diamond-shaped mounting hole 91, the second diamond-shaped mounting hole 64, and the positioning pin 62 have the same shape.

[0057] After the positioning pin 62 passes through the first rhombus mounting hole 91 and the second rhombus mounting hole 64, the positioning pin 62 rotates until the bottom rhombus is perpendicular to the first rhombus mounting hole 91 and the second rhombus mounting hole 64. Then, the locking nut 63 is installed on the threaded part of the positioning pin 62, and the locking nut 63 is tightened to fix the motor base 61 to the mounting plate 9.

[0058] The thickness of the motor base 61 is selected according to the required installation height of the rotor motor 2. Adjusting the installation position of the locking nut 63 on the positioning pin 62 can accommodate motor bases 61 of different thicknesses.

[0059] like Figure 6 and Figure 1 As shown, the movable seat 42 includes a slider 421 and a base plate 422. The slider 421 is welded to the middle position of the upper surface of the base plate 422. Displacement structures 7 are welded to both sides of the upper surface of the base plate 422 for adjusting the height of the stator body 1.

[0060] like Figure 2 As shown, the displacement structure 7 includes two limiting frames 71, two second motors 72, two second threaded rods 73, and a lifting platform 74. The two limiting frames 71 are welded to both sides of the upper surface of the base plate 422. A second threaded rod 73 is connected to each of the two limiting frames 71 through bearings. The two second motors 72 are fixedly installed on the two limiting frames 71 by screws. The output shaft of the second motor 72 passes through the limiting frame 71 and connects to the second threaded rod 73. The lifting platform 74 is threaded onto the two second threaded rods 73.

[0061] The second motor 72 drives the second threaded rod 73 to rotate, which in turn moves the lifting platform 74 up and down, thereby adjusting the height of the stator body 1 and ensuring that the stator body 1 and the rotor body 3 are set in a corresponding manner.

[0062] like Figure 10As shown, the stator body 1 is detachably mounted on the lifting platform 74 via the second mounting structure 75. The second mounting structure 75 is the same as the first mounting structure 6. The lifting platform 74 is provided with a first diamond-shaped mounting hole 91, and the bottom of the stator body 1 is provided with a second diamond-shaped mounting hole 64. After the positioning pin 62 passes through the first diamond-shaped mounting hole 91 and the second diamond-shaped mounting hole 64, the locking nut 63 is installed on the threaded part of the positioning pin 62. Tightening the locking nut 63 fixes the stator body 1 to the lifting platform 74, so that different stator bodies 1 can be mounted on the movable seat 42.

[0063] like Figure 1 , Figure 8 and Figure 9 As shown, the stator body 1 and the rotor body 3 are provided with an adjustable length protective shell 8. The protective shell 8 includes an upper shell 81, a lower shell 82, an extension shell 83, and fixing bolts 84. The upper shell 81 is connected to one end of the rotor motor 2 by a bearing. The upper shell 81 has a slot inside. The end of the lower shell 82 away from the displacement structure 7 is connected to the extension shell 83. The extension shell 83 is inserted into the slot of the upper shell 81. The upper shell 81 and the extension shell 83 are provided with two fixing holes 85 respectively. The fixing bolts 84 pass through the fixing holes 85 to fix the installation distance between the upper shell 81 and the lower shell 82.

[0064] In this embodiment, the upper shell 81 is the part of the protective shell 8 that is close to the rotor motor 2, and the lower shell 82 is the part that is away from the rotor motor 2. When the two fixing holes 85 on the upper shell 81 and the two fixing holes 85 on the extension shell 83 are connected by fixing bolts 84, the extension shell 83 is completely inserted into the slot, and the protective shell is shortened. When the fixing holes 85 on the upper shell 81 that are away from the rotor motor 2 and the fixing holes 85 on the lower shell 82 that are close to the rotor motor 2 are fixed by fixing bolts 84, the protective shell 8 is extended and adjusted according to the position and size of the installed stator body 1 and rotor body 3.

[0065] like Figure 3 As shown, the movable base 42 is connected to the heat dissipation tank 12 by screws. The heat dissipation tank 12 is connected to the spray pipe 13 and the return pipe 14. The other end of the spray pipe 13 and the return pipe 14 is connected to the upper shell 81. Water passage holes are provided on the upper shell 81 and the extension shell 83 at the connection of the spray pipe 13 and the return pipe 14 to ensure that the spray pipe 13 and the return pipe 14 can still be used normally and will not be blocked after the relative position of the upper shell 81 and the extension shell 83 changes.

[0066] Cooling water in the radiator 12 enters the protective housing 8 through the spray pipe 13 and is returned to the radiator 12 through the return pipe 14. Cooling water inside the radiator 12 enters the protective housing 8 through the spray pipe 13 to dissipate heat from the stator body 1 and the rotor body 3, and then returns to the radiator 12 through the return pipe 14.

[0067] In this embodiment, the cooling water in the heat dissipation tank 12 needs to be replaced regularly to prevent too much heat-absorbing cooling water from entering the heat dissipation tank 12, which would cause the cooling water temperature to rise and affect the heat dissipation effect.

[0068] The working process of this embodiment:

[0069] The adjustment base 4 of this device is suitable for permanent magnet speed controllers of different sizes and models. The rotor motor 2 and rotor body 3 of the permanent magnet speed controller are installed on the fixed base 41 through the first mounting structure 6. The first diamond-shaped mounting hole 91 on the mounting plate 9 ensures that rotor motors 2 of different sizes can be installed through the first mounting structure 6. After installation, the stator is installed on the displacement structure 7 through the second mounting structure 75. The stator and rotor are aligned by adjusting the displacement structure 7 to avoid the inability to adjust the stator height after changing to a new size, which would cause the stator body 1 and rotor body 3 to be unable to be installed in a corresponding manner. This also ensures that the height of permanent magnet speed controllers of different models can be adjusted to a suitable position, thus ensuring the practicality of this device. After installation, the cleaning structure 5 is activated to clean foreign objects on the fixed base 41 to prevent foreign objects from affecting the accuracy of position adjustment. Then, the drive structure 43 is activated to drive the movable base 42 to move on the fixed base 41 and adjust the distance between the rotor body 3 and the stator body 1. At this time, the stator body 1 and the rotor body 3 will not be displaced in other directions, ensuring the stability of the distance adjustment. The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
