Abstract
The invention relates to a guide rail which is used for guiding relative motion for mechanical components, in particular to a switchable permanent magnet magnetic suspension guide rail. The switchable permanent magnet magnetic suspension guide rail comprises a quiet rail and a moving rail, wherein the quiet rail and the moving rail are capable of moving relatively. Interactional coupled magnetic boxes are respectively arranged on the quiet rail and the moving rail. Magnetic field action faces are arranged on each pair of magnetic boxes, wherein the magnetic field action faces are arranged in an opposite mode, the opposite two magnetic field action faces are located on magnetic force lines with the same running direction, and interaction forces of a pair magnetic boxes is repulsive force. According to the switchable permanent magnet magnetic suspension guide rail, permanent magnet magnetic fields are used for supplying suspension and constraint motive power and relatively traditional electromagnetic equipment, equipment cost is greatly reduced, meanwhile, the action magnetic fields of the permanent fields can be opened or closed according to needs, and the equipment is convenient to install and maintain.
Description
Technical field
The present invention relates to the guide rail for mechanical part relative motion guiding, but a kind of switch permanent magnetism magnetic suspension guide rail structure specifically.
Background technology
At present, the use occasion of guide rail is a lot, can be divided into sliding friction guide rail, rolling friction guide rail, hydrostatic slideway etc. by kind, but they all belongs to the contact guide rail, i.e. moving guide rail and direct or indirect being in contact with one another of support rails.Direct contact type guide mechanism efficient is low, and structural member is easy to wear, and indirect contact formula guide mechanism efficient is higher, but sub-carrier (as ball etc.) is easy to wear, need often to change, if use lubricating oil to be used as sub-carrier, can increase the complex structure degree of guide rail.
Present magnetic levitation technology is relatively ripe, generally produce magnetic field with superconductor technology, but this technical costs is high, can't popularize.
The permanent magnetism magnetic suspension technology more and more comes into one's own, but there is the shortcoming that can't close in permanent magnetic field, has had a strong impact on detection and the maintenance of permanent magnetism equipment.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of and provide magnetic field by permanent magnetic material, but and effect magnetic field can open and close easily, installation and maintenance switch permanent magnetism magnetic suspension guide rail easily.
But switch permanent magnetism magnetic suspension guide rail of the present invention includes quiet rail and the moving rail that can relatively move, and is respectively arranged with interactional paired magnetic case on quiet rail and moving rail; Every a pair of magnetic case has the magnetic fields face that is oppositely arranged, and the magnetic line of force at relative two magnetic fields face places moves towards identical, and the interaction force that makes a pair of magnetic case is repulsion.
Described magnetic case comprises a housing, be mounted with an iron core and three permanent magnets in housing, the bottom surface direction of iron core is the magnetic fields face, three permanent magnets are respectively to be positioned at the rotary magnet of iron core both sides and the top magnet on end face, two rotary magnets lay respectively in the interior mounting groove of two rotating shafts, and can rotate with rotating shaft; The pole orientation of top magnet is vertical with the iron core end face, rotary magnet in rotary course its pole orientation can with the lateral vertical of iron core or parallel; Can open or close the magnetic field in the magnetic fields face outside by the rotation of rotary magnet.
The material of described rotating shaft is permeability magnetic material.
Rotary magnet place on described magnetic fields face is provided with the magnetic circuit gap.Described magnetic circuit gap location is provided with protective cover.
Magnetic case on described quiet rail and moving rail is provided with at least three pairs, lays respectively at bottom and both sides.The magnetic case of bottom is for generation of suspending power, and the magnetic case of both sides is for generation of restraining force.
The both sides of described quiet rail and bottom are provided with a plurality of magnetic casees respectively, and a plurality of magnetic casees are arranged along the rail length direction, make the magnetic case that moves in the rail moving process on rail can be successively with quiet rail on the magnetic case match and interact.
The present invention utilizes permanent magnetic field to suspend and constraint power for magnetic suspended guide provides, and relatively traditional electromagnetic equipment greatly reduces equipment cost; Simultaneously, it acts on magnetic field and can open or close as required, has facilitated the equipment installation and maintenance.
