Description
Technical field
The present invention relates to the guide rail for mechanical part relative motion guiding, specifically one can switch permanent magnetism magnetic suspension guide rail structure.
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., but they all belongs to contact guide rail by kind, i.e. dynamic guide rail and direct or indirect the contacting with each other of support rails.Direct contact type guide mechanism efficiency is low, and structural member is easy to wear, and indirect contact guide mechanism efficiency 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, then can increase the complex structure degree of guide rail.
Present magnetic levitation technology relative maturity, the general superconductor technology that uses produces magnetic field, but this technical costs is high, cannot popularize.
Permanent magnetism magnetic suspension technology more and more comes into one's own, but permanent magnetic field exists the shortcoming that cannot close, and has had a strong impact on detection and the maintenance of permanent magnet devices.
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, and reaction magnetic can open and close easily, installation and maintenance easily can switch permanent magnetism magnetic suspension guide rail.
Of the present invention can switch permanent magnetism magnetic suspension guide rail include can the quiet rail of relative movement and dynamic rail, quiet rail and dynamic rail are respectively arranged with interactional paired magnetic case; Every a pair magnetic case has the magnetic fields face be oppositely arranged, and the magnetic line of force at two relative magnetic fields face places moves towards identical, makes the interaction force of a pair magnetic case be repulsion.
Described magnetic case comprises a housing, an iron core and three permanent magnets are mounted with in housing, the direction, bottom surface of iron core is magnetic fields face, three permanent magnets are be positioned at the top magnet on the rotary magnet of iron core both sides and end face respectively, two rotary magnets lay respectively in the mounting groove in two rotating shafts, and can rotate with rotating shaft; Top magnet pole orientation vertical with iron core end face, rotary magnet in rotary course its pole orientation can with the lateral vertical of iron core or parallel; The magnetic field outside magnetic fields face can be opened or closed 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 magnetic circuit gap.Described magnetic circuit gap location is provided with protective cover.
It is at least three right that magnetic case on described quiet rail and dynamic rail is provided with, and 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 multiple magnetic case respectively, and multiple magnetic case, along the arrangement of rail length direction, enables magnetic case in rail moving process on dynamic rail match with the magnetic case on quiet rail and interact successively.
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; Meanwhile, its reaction magnetic can open or close as required, facilitates equipment installation and maintenance.

Fig. 2 is the structural representation of a pair magnetic case of embodiment of the present invention when closing in external magnetic field;
Fig. 3 is the structural representation of a pair magnetic case when external magnetic field is opened of the embodiment of the present invention.
Embodiment
As shown in Figure 1, this can switch permanent magnetism magnetic suspension guide rail include can the quiet rail 1 of relative movement and dynamic rail (not providing in figure), quiet rail and dynamic rail are respectively arranged with interactional paired magnetic case 2; Every a pair magnetic case has the magnetic fields face be oppositely arranged, and the magnetic line of force at two relative magnetic fields face places moves towards identical.
Magnetic case 2 comprises a housing 21, housing 21 bottom surface is magnetic fields face, an iron core 22 and three permanent magnets are mounted with in housing, direction, iron core bottom surface is magnetic fields face, three permanent magnets are be positioned at the top magnet 24 on the rotary magnet 23 of iron core 22 both sides and end face respectively, two rotary magnets 23 lay respectively in the mounting groove in two rotating shafts 25, and can rotate with rotating shaft 25; Top magnet 24 pole orientation vertical with iron core end face, rotary magnet 23 in rotary course its pole orientation can with the lateral vertical of iron core or parallel; The magnetic field outside magnetic fields face can be opened or closed by the rotation of rotary magnet 23.Rotary magnet place on described magnetic fields face is provided with magnetic circuit gap 26.Magnetic circuit gap location is provided with protective cover 27.
It is at least three right that magnetic case on described quiet rail and dynamic rail is provided with, and 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 quiet rail and bottom are provided with multiple magnetic case respectively, and multiple magnetic case, along the arrangement of rail length direction, enables magnetic case in rail moving process on dynamic rail match with the magnetic case on quiet rail and interact successively.
As shown in Figure 2, the magnetic case magnetic fields face of figure middle and upper part is in lower surface, and the magnetic case magnetic fields face of bottom is in upper surface for a pair magnetic case structure when magnetic field open mode; Their top magnet 24 and the pole orientation of two rotary magnets 23 all towards iron core, thus produce magnetic field in the same way on opposite sides, mutually repel.And the magnetic field closed condition of magnetic case as shown in Figure 3, in figure, the pole orientation of the rotary magnet 23 of each magnetic case all goes to and pushes up magnet 24 pole orientation (parallel with iron core side) in opposite directions, make the field circuit between each magnet be mainly home loop, thus close the magnetic field outside magnetic fields face.
