Description
Technical field
The present invention relates to a kind of magnetic variable system of field of mechanical technique, relate to a kind of extendible swing magnetic suspending device more specifically.
Background technology
Existing disclosed magnetic suspension series mostly is the whirligig (bearing, blender, tellurion etc. are more common in its application) that sways or the device (vibration absorber, contactor etc. are more common in its application) of magnetic suspension vibrations.The shortcoming of this class levitation device is to realize the motion of two degrees of freedom.
Find that through the literature search to prior art Chinese utility model patent 200420027342.4 discloses " magnetic levitation system of band housing ", by suspended substance, solenoid, movable branching rod, housing are formed.The main points of this utility model are to have increased a housing outside suspended matter, and the direction of motion of restriction suspended matter increases its stability.Its technical scheme is in case top solenoid to be installed, and there is magnet the inside of suspended matter, and inhale mutually with magnet solenoid energising back, and when suction and suspended matter were equal in weight, suspended matter just can be suspended in desired location.More than Zhuan Zhi defective is that suspended material still can rotate under the state that suspends, and movement locus is limited.Therefore magnetic levitation system mostly is the whirligig (bearing, blender, tellurion etc. are more common in its application) that sways or the device (vibration absorber, contactor etc. are more common in its application) of magnetic suspension vibrations.
Summary of the invention
The objective of the invention is to overcome the above-mentioned shortcoming of original levitation device, a kind of extendible swing magnetic suspending device is provided, this device uses two springs supporting movement platforms, avoids platform to rotate; The pendulum angle of platform increases the stability of platform only by the electric current decision.The two-dimentional pendulous device of expanding on the basis of this device, the motion on the different dimensions does not independently interact mutually.
The present invention is achieved by the following technical solutions, the present invention includes: pedestal, two block permanent magnets, two U type magnetic conductors, two square coil windings, two coil stationary sheets, two springs, motion platform, connector.The two block permanent magnet S utmost points are fixed together with two any side inwalls of U type magnetic conductor respectively, form two U type permanent magnets, and the magnetic line of force of this U type permanent magnet is pointed to the opposite side inwall of U type magnetic conductor by the N utmost point of permanent magnet.Two springs are fixed with connector in the motion platform bottom, and the motion platform bottom vertical is fixed two square coil windings with two coil stationary sheets respectively in the both sides of two springs lines.Respectively two U type permanent magnets below two square coil windings.Two U type magnetic conductors pass two square coil windings respectively, and make the initial position of square coil winding be positioned at the center of permanent magnet, U type magnetic conductor structure height direction.Feeding electric current in two square coil windings can utilize Ampere force to make the motion platform swing.
Be fixed on the motion platform bottom before and after two springs of the present invention, the supporting movement platform makes motion platform have the pitching degree of freedom.At first two square coil windings are switched on during work, according to the sense of current in definite respectively two the square coil windings of the riding position of two U type permanent magnet poles.When two square coil windings feed electric current, place the energising square coil winding in U type magnetic field that permanent magnet produces to be subjected to the effect (right-hand rule) of Ampere force, Ampere force is swung motion platform to the left and right.At this moment, effect when motion platform is subjected to springs and recovers elastically-deformable elastic force and above-mentioned Ampere force, when balance between two forces, the motion platform inclination angle reaches stable.Therefore the Ampere force difference that different current strength produces feeds suitable electric current to the square coil winding and can obtain the inclination angle that needs, utilizes this point to come the inclination angle of controlled motion platform swing by the size of control input current.Use two springs supporting movement platforms in the device, eliminated the latter's issuable reversing when swinging.During actual the use, can on each dimension, increase the number of magnet according to the needs of Ampere force size.
Apparatus of the present invention have autgmentability, and the identical device of one deck that can superpose on the basis of above-mentioned pendulous device makes the motion dimension of motion platform increase to two dimension.Used four magnet respectively on two dimensions in the concrete device for carrying out said, the size of making a concerted effort has increased one times.This device comprises two pedestals, eight block permanent magnets, eight U type magnetic conductors, eight square coil windings, eight coil stationary sheets, four springs, a motion platform.Eight block permanent magnets and U type magnetic conductor are combined into eight U type permanent magnets in the manner described above respectively; Place on one side first and second U type permanent magnet on first pedestal, the another side symmetry is placed third and fourth U type permanent magnet, about two corresponding.Build a pendulous device with same procedure, second pedestal replaces original motion platform.Based on second pedestal, arrange about with connector and to be fixed on the platform bottom third and fourth springs, the supporting movement platform, symmetry is placed the 5th to the 8th U type permanent magnet on second pedestal.U type magnetic conductor passes the square coil winding, and makes the initial position of square coil winding be positioned at the center of permanent magnet, U type magnetic conductor structure height direction.Control second pedestal by the size of control input current and drive motion platform and swing, meanwhile, the swing of carrying out fore-and-aft direction independently that motion platform can be under the control of electric current.The swaying direction of platform is expanded and is two dimension like this.Compare with other two dimensional motion devices, independent mutually between its two latitudes, can not be coupled mutually.
Compare with other same devices, advantage of the present invention is to adopt the way of separating, design a kind of magnetic levitation system of extendible swing, the two-dimentional pendulous device of on the basis of this device, expanding, motion on the different dimensions does not independently interact mutually, and use two springs on each dimension, avoid platform to rotate.
