Abstract
The utility model provides a stack magnetic circuit multifunctional switch formula permanent magnetism magnetic force unit, including fixed magnetic pole, activity magnetic pole, magnetic path, the overall arrangement forms an integral unit structure. The fixed mounting inslot at fixed leading pole -tip is adorned to fixed magnetic path, and its N, S extremely immobilize, activity magnetic path dress through rotating movable magnetic pole, can make N, S pole -change direction in the cylindrical cavity of activity trailing pole -tip, the activity magnetic pole adopts vertical rotation and adorns the bearing at both ends, extremely with one side the time, fixed magnetic path externally manifests magnetism with the magnetic field strength intensity stack of movable magnetic path as N, the S of fixed magnetic path and activity magnetic path. As the N of fixed magnetic path and activity magnetic path, when S is extremely opposite, fixed magnetic path does not externally show magnetism with activity magnetic path inter attraction. The utility model provides a stack magnetic circuit multifunctional switch formula permanent magnetism magnetic force unit can effectively carry high magnetic field intensity, reduce remanence to because of the short greatly reduced of magnetic pole the processing degree of difficulty.

Power unit.
Background technology
Double magnetic force units, are mainly used in Magnetic Control technology, and its operation principle is by handle or other transmission sides
Formula controls detachable pole, and when detachable pole is consistent with fixed magnetic pole polarity, magnetic circuit is overlapping, externally manifests magnetic and draws ferromagnetism
Weight；Form internal magnetic loop when detachable pole and fixed magnetic pole polarity are different and externally do not show magnetic, loosen weight；Typically
Using fixed magnetic pole up, the structure in lower section for the detachable pole.Because of process issues, magnetic pole length direction is restricted, should
Technology is difficult to produce large-tonnage crane gear；Detachable pole is affected by machining accuracy with outer magnetic pole fit clearance, the little manufacture in gap
High cost, the loss of the big magnetic force in gap is also big；Fixed magnetic pole magnetic patch is remote with a distance from lifting thing, and magnetic field force also cannot make full use of；Live
Dynamic magnetic pole horizontal rotation, radius of turn is limited by space.The utility model aims to solve the problem that the problems referred to above.
Content of the invention
The utility model provides that a kind of magnetic field intensity is big, magnetic force is stable, magnet steel firm position, easily manufactured superposition magnetic
Road Multifunctional start-close permanent-magnet unit.
Superposition magnetic circuit Multifunctional start-close permanent-magnet unit, including fixed magnetic pole, detachable pole, is loaded in fixed magnetic pole
Fixing magnetic patch, the movable magnetic patch being loaded in detachable pole, detachable pole two end axles bearing and bearing, cover plate it is characterised in that：
Fixing magnetic patch is distributed in front and back end with movable magnetic patch, and the vertical installation of detachable pole, two ends are respectively arranged with bearing, vertical rotating.
Described fixed magnetic pole, two magnetic poles about point, if cut along center line, left and right two magnetic pole is symmetric relation.Left and right
Connected by nonmagnetic substance in the middle of two magnetic poles, it is to avoid internal magnetic field forms path；Left and right two magnetic pole first halfs and contiguous block one
Rise and form fixed installation groove, be used for fixing magnetic patch installation；It is processed into a cylindrical cavity after latter half and contiguous block connection, use
To receive detachable pole.
Described detachable pole, interlude dimidiation, make of permeability magnetic material；Two ends are non-magnet material, and all process
There is bearing position, one end also has spindle nose, spindle nose is beneficial to handle manpower and rotates and machine driving；Interlude dead slot built-in activity magnetic patch,
Movable magnetic patch is fixed it is ensured that magnetic patch is not subjected to displacement with detachable pole by magnetic isolation plate positioning.
Described magnetic patch, is separately mounted in fixed magnetic pole and detachable pole groove；Magnetic patch size value is also crucial, because magnetic
Steel unit area directly affects the magnetic field intensity of permanent magnetism sucking and lifting device；Two magnetic patch consistent size it is ensured that under demagnetized state permanent magnetism inhale
Device for hoisting does not have remanent magnetism.
Described bearing block, is made by non-magnet material, prevents formation internal magnetic field from causing magnetic force to lose；Up and down each one
Individual, two are attached separately to detachable pole two ends blending bolt and are connected with fixed magnetic pole, buried bearing, prevent detachable pole deflection one
Side is it is ensured that detachable pole rotates flexibly.
Described cover plate, is arranged on fixed magnetic pole top, is made by non-magnet material, prevents fixing magnet steel from exposing and magnetic
Power is lost.

Specific embodiment
It is superimposed magnetic circuit Multifunctional start-close permanent-magnet unit as shown in figs. 1 and 2, including fixed magnetic pole 1, fixing magnetic patch
2nd, cover plate 3, top chock 4, bearing 5, handle 6, detachable pole 7, movable magnetic patch 8, bearing 9, step 10.
Rotate detachable pole 7, when N, S pole of detachable pole N, S pole and fixed magnetic pole is in the same side（As Fig. 3）When, activity
Magnetic pole is superimposed with the magnetic strength of fixed magnetic pole, externally shows magnetic, produces suction to magnetic conduction material；When detachable pole N, S pole and admittedly
N, S pole determining magnetic pole is in opposite side（As Fig. 4）When, in N the and S pole of detachable pole is formed with S the and N pole of fixed magnetic pole respectively
Portion's magnetic circuit, does not externally show magnetic, and magnetic conduction material is not produced with suction, the demagnetized state as often said.
