Description

Technical Field

[0001] The invention relates to the technical field of magnetic levitation, in particular to a magnetic levitation guidance control device. Background Art

[0002] With the continuous development of mechanical and electronic technology, the demand for mechatronic structures has become more diversified. Traditional coarse-motion mechanical structures are difficult to meet the needs of high-precision transmission and have gradually been replaced by more complex and precise mechanisms. In order to achieve the complex movement of the motion module in the horizontal plane, the slider and the motion guide rail can be combined to control the X- and Y-direction movement respectively and synthesize them into horizontal plane movement. However, the processing accuracy of traditional mechanical guide rails and guide rail brackets is difficult to guarantee, which will cause shape and position errors during installation and is difficult to adjust. In addition, the mass of the moving guide rail is large, which will increase the power requirements of the drive motor and the control difficulty will also increase. In modern precision machinery design, magnetic levitation technology can be used to reduce the friction of mechanical transmission, thereby improving the movement accuracy of components. When the magnetic levitation system is working, the magnetic force of the coil can be controlled by changing the current, and the suspension distance can be fine-tuned in conjunction with the permanent magnet. At the same time, with the help of magnetic traction design, the magnetic levitation device can be used as a power source for mechanical movement. However, due to the influence of electromagnetic force during assembly and equipment movement, magnetic anomalies may occur when the equipment is magnetically levitated, causing the equipment to move to an offset or tilt. When such a situation occurs, if the suspended equipment cannot be guided and adjusted in time, the equipment may be unable to continue working. It may also cause damage to the permanent magnet when the equipment lands, thereby affecting the use of the equipment.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 7 , the present invention provides a technical solution:

[0030] A magnetic levitation guide control device comprises a connecting plate 1 and a track assembly 3, permanent magnet assemblies 2 are arranged on both sides of the connecting plate 1, the permanent magnet assemblies 2 are magnetically slidably connected in the track assembly 3, a rotating shaft 4 is rotatably connected in the connecting plate 1, a self-locking mechanism 5 is installed on the rotating shaft 4, a spacing guide mechanism 11 is arranged on the lower side of the connecting plate 1, the spacing guide mechanism 11 is movably connected to the side wall of the track assembly 3, a full gear 19 is installed on the rotating shaft 4, a support seat 20 is fixedly connected on both sides of the connecting plate 1, a balance guide mechanism 21 is arranged in the support seat 20, an alarm mechanism 27 is arranged in the connecting plate 1, and a driving mechanism 33 is arranged on the connecting plate 1, and the driving mechanism 33 is movably connected to the spacing guide mechanism 11 and the balance guide mechanism 21 respectively;

[0031] During operation, the permanent magnets in the permanent magnet component 2 and the track component 3 are controlled to form a magnetic force, and then the permanent magnet component 2 lifts the connecting plate 1, and at the same time, the magnetic force is used to move it, thereby ensuring the suspended movement of the equipment. When the equipment is moving, if the permanent magnet component 2 encounters an abnormality or the permanent magnet component 2 is partially magnetic, the connecting plate 1 may tilt. At this time, the squeezing ball 31 in the alarm mechanism 27 slides and cooperates with the elastic component 28 to make the alarm 32 sound an alarm, thereby reminding people so that they can inspect and adjust the equipment. At the same time, after the alarm mechanism 27 sounds an alarm, the driving mechanism 33 will guide according to the abnormality of the equipment when the equipment tilts. The driving mechanism 33 controls the balancing guide mechanism 21 to work. At this time, the balancing guide mechanism 21 extends, and at the same time, the balancing guide mechanism 21 contacts the upper and lower sides of the inner wall of the track, so that the connecting plate 1 is supported by the upper and lower sides at the same time, so that the connecting plate 1 forms a balanced state. At this time, the device can continue to move under the guidance of the second guide wheel 26 during movement, thereby avoiding the device being unable to support one end when it tilts, causing damage to parts during the movement of the device, thereby causing the occurrence of dangerous accidents. At the same time, when the distance between the connecting plate 1 and the left and right side walls of the track assembly 3 in the device is different, the driving mechanism 33 controls the distance guide The mechanism 11 works. When the spacing guide mechanism 11 works, the first guide wheel 18 extends out, and at the same time, the first guide wheel 18 is squeezed on the left and right side walls of the track assembly 3, so that the connecting plate 1 is in the middle position, so that it can continue to work, and it can also stop working so that people can carry out maintenance. The spacing guide mechanism 11 and the balance guide mechanism 21 in the equipment cooperate to effectively ensure the stability of the equipment during work and the safety of the guided movement, prevent the equipment from tilting or excessive friction during movement, further improve the safety and convenience of use of the equipment, and ensure the guidance accuracy of the equipment.

[0032] As a further solution of the present invention, the self-locking mechanism 5 includes a fixed disk 6, a lock groove 7, a rotating disk 8, a first spring 9 and a locking block 10. The fixed disk 6 is installed on the connecting plate 1, and a plurality of lock grooves 7 are opened in the fixed disk 6. The rotating disk 8 is installed on the rotating shaft 4. A plurality of first springs 9 are fixedly connected in the rotating disk 8. A locking block 10 is installed at one end of the first spring 9, and the locking block 10 is movably connected in the lock groove 7.

[0033] During operation, when the rotating shaft 4 rotates, the rotating shaft 4 controls the rotating disk 8 to rotate. At this time, the locking block 10 installed at one end of the first spring 9 moves in the locking groove 7. When the rotating shaft 4 rotates, the rotating shaft 4 controls the spacing guide mechanism 11 to open. When the spacing guide mechanism 11 moves to a suitable position, the locking block 10 is located in the locking groove 7 and is subjected to the elastic force of the first spring 9 to maintain the relative fixation between the fixed disk 6 and the rotating disk 8, thereby keeping the spacing guide mechanism 11 in an open state. At this time, the device can be moved with the spacing guide mechanism 11 as the support force, while ensuring the stability of the device during movement and avoiding the situation where the device is damaged due to large friction caused by magnetic force.

[0034] As a further solution of the present invention, the spacing guide mechanism 11 includes a guide plate 12, a guide groove 13, a rotating plate 14, a slide plate 15, a pull rod 16, a fixed rod 17 and a first guide wheel 18. Two guide plates 12 are installed on the lower side of the connecting plate 1. The guide groove 13 is opened in the guide plate 12. The rotating plate 14 is installed on the rotating shaft 4. Two slide plates 15 are slidably connected between the two guide grooves 13. The pull rod 16 is rotatably connected between the slide plate 15 and the rotating plate 14. Two fixed rods 17 are fixedly connected to the slide plate 15. The first guide wheel 18 is rotatably connected to the fixed rod 17. The surface of the first guide wheel 18 is provided with a soft rubber layer;

[0035] During operation, when the rotating shaft 4 rotates, the rotating shaft 4 controls the rotating plate 14 to rotate. When the rotating plate 14 rotates, the rotating plate 14 moves the two slides 15 under the guidance of the guide groove 13 through the pull rod 16, and at the same time moves the fixed rod 17 to the side of the track assembly 3. At this time, the first guide wheel 18 contacts the side of the track assembly 3, and at the same time, the two sides of the connecting plate 1 are squeezed so that the distance between it and the two sides of the track assembly 3 is equal. At this time, the equipment can continue to guide and move, and can also stop for maintenance, thereby ensuring the stability and safety of the equipment during movement and preventing it from offset.

[0036] As a further solution of the present invention, the balance guide mechanism 21 is movably connected to the upper and lower sides of the inner wall of the track assembly 3, and the balance guide mechanism 21 includes a rotating sleeve 22, a screw rod 23, a limiting groove 24, a limiting rod 25 and a second guide wheel 26. The support seat 20 is rotatably connected with the rotating sleeve 22, and the rotating sleeve 22 is internally threaded with two screw rods 23. The screw rod 23 is provided with a limiting groove 24, and the connecting plate 1 is fixedly connected with the limiting rod 25, and the limiting rod 25 is slidably connected in the limiting groove 24. The thread directions of the two screw rods 23 are opposite, and a second guide wheel 26 is installed at one end of the screw rod 23;

[0037] During operation, when the movable plate is tilted, the driving mechanism 33 controls the rotating sleeve 22 to rotate. When the rotating sleeve 22 rotates, the screw rod 23 connected to the inner thread of the rotating sleeve 22 moves. At this time, the two screw rods 23 move away from each other. When the screw rod 23 moves to a suitable position, the second guide wheel 26 contacts the upper and lower side walls of the track assembly 3, so that the connecting plate 1 is centered in the track assembly 3, thereby avoiding the equipment from tilting, which causes greater friction when it moves, making it more precise when adjusted and more convenient to guide.

[0038] As a further solution of the present invention, the alarm mechanism 27 includes multiple sets of elastic components 28, squeezing balls 31 and alarms 32, the multiple sets of elastic components 28 are arranged in a ring, the squeezing balls 31 are located between the multiple elastic components 28, and the alarm 32 is installed on the connecting plate 1;

[0039] During operation, when the equipment is tilted, the squeezing ball 31 slides to the tilted side. At this time, the squeezing ball 31 can be connected through the contact of the elastic component 28, so that the alarm 32 sounds an alarm, and then the equipment completes the alarm work. At this time, the equipment can adjust the balance distance and remind people to carry out maintenance, thereby ensuring the subsequent use of the equipment and avoiding the occurrence of danger caused by continued use when a fault occurs.

[0040] As a further solution of the present invention, the elastic component 28 includes a second spring 29 and a contactor 30. The second spring 29 is fixedly connected in the connecting plate 1. Two contactors 30 are arranged inside the second spring 29. The two contactors 30 are movably connected.

[0041] During operation, when pressure is applied to squeeze the second spring 29, the length of the second spring 29 is compressed, and at the same time, the contactor 30 inside the second spring 29 is in contact and connected. At this time, the alarm 32 sounds an alarm. When the equipment is adjusted, the squeezing ball 31 is reset, and at the same time, the contactor 30 is moved away, so that it is reset again. Repeating the work can effectively ensure the stability and safety of the equipment.

[0042] As a further solution of the present invention, the driving mechanism 33 includes a first rotating column 34, a second rotating column 35, a third rotating column 36, a half gear 37, a slot 38, a driving motor 39 and a telescopic rod 40. The first rotating column 34, the second rotating column 35 and the third rotating column 36 are rotatably connected to the connecting plate 1. The third rotating column 36 is transmission-connected to the first rotating column 34. The first rotating column 34 is transmission-connected to the two balancing guide mechanisms 21. The second rotating column 35 is equipped with a half gear 37, and the half gear 37 is meshingly connected to the full gear 19. The second rotating column 35 and the third rotating column 36 are both provided with a slot 38. The driving motor 39 is installed on the connecting plate 1. The output end of the driving motor 39 is fixedly connected to the telescopic rod 40. Two pairs of card blocks are installed on the telescopic rod 40, and the card blocks are movably connected in the card slot 38.

[0043] During operation, when the telescopic rod 40 is extended, the telescopic rod 40 and the second rotating column 35 are movably connected. At this time, a group of card blocks are connected to the card slots 38 of the second rotating column 35. At the same time, the driving motor 39 drives the full gear 19 to rotate through the half gear 37 on the second rotating column 35, thereby opening the spacing guide mechanism 11. At the same time, the self-locking mechanism 5 can lock the spacing guide mechanism 11 to ensure its open state, thereby ensuring the time distance guidance of the equipment. When the telescopic rod 40 is shortened, the card block is disengaged from the card slots 38 on the second rotating column 35, and is connected to the card slots 38 under the third rotating column 36. At this time, the driving motor 39 controls the first rotating column 34 to rotate through the third rotating column 36, thereby making the balancing guide mechanism 21 work. At this time, the equipment can adjust the balancing guide of the connecting plate 1 to make the equipment more stable during use and avoid tilting.

[0044] As a further solution of the present invention, two pairs of slots 38 are provided on the third rotating column 36, and the two pairs of slots 38 are respectively located at two ends of the third rotating column 36;

[0045] During operation, when the device is tilted and the spacing on both sides needs to be adjusted, the telescopic rod 40 is extended, and at the same time, the two sets of blocks on the telescopic rod 40 are respectively engaged with the slots 38 on the second rotating column 35 and the slots 38 on the third rotating column 36. At this time, the driving motor 39 can simultaneously drive the second rotating column 35 and the third rotating column 36 to rotate through the telescopic rod 40, so that the device can simultaneously open the spacing guide mechanism 11 and the balance guide mechanism 21, so that it can adjust the dual guides at the same time, so that the device can be adjusted more accurately and the guidance is safer during use.
