Abstract
The invention discloses a sealing method for preventing magnet block fragments from getting stuck in a rotating magnetic pole and solves the problem that internal and external magnetic poles of a hoisting permanent magnetic crane get stuck by magnet block fragments so that reliable rotation of the internal magnetic pole in an inner hole of the external magnetic pole is guaranteed. When an internal and external magnetic pole short-circuit type hoisting permanent magnetic crane commonly used in the existing market is used, magnet blocks in the internal magnetic pole break, are ejected out and get stuck in the hole of the external magnetic pole frequently, the internal magnetic pole cannot rotate continuously, and accordingly, the hoisting permanent magnetic crane fails in cyclic magnetization or demagnetization and loses working capacity. The sealing method is provided to solve the problem, a groove is formed in the internal magnetic pole, a sealing plate is further arranged in the groove, and the defect caused by breaking and ejecting out of the magnet blocks can be prevented.
Description
Technical field
The present invention relates to magnetic force applied technical field, and in particular to a kind of in rotary pole, to prevent magnetic piece fragment stuck
Mouth-sealing method.
Background technology
Lifting Permanent Magnetic Crane is the magnetic force using permanent magnet, carrys out lifting, carries iron and steel parts.Commonly use currently on the market
The Lifting Permanent Magnetic Crane of inside and outside magnetic pole short-circuit type, the magnetic piece that Jing often occurs in internal magnetic pole in use rupture, eject and be stuck in
In outer magnetic pole hole, prevent internal magnetic pole from continuing rotation, so that the Lifting Permanent Magnetic Crane can not circulate magnetic or demagnetization, lose the job
Ability.
The ndfeb magnet that Lifting Permanent Magnetic Crane is adopted, magnetic force are big, but are easy to broken.Detachable pole fixes ndfeb magnet
Method be all that Bian machineries are riveted tightly, during this is riveted tightly, some neodymium ferromagnetic blocks are very possible just broken.If assembling
Process is not found, and the magnetic piece fragment for being easy in use occur in internal magnetic pole flies out, so as to stuck in inside and outside magnetic
In the gap of pole.
The present invention is aiming at the problem, proposes a kind of recessing on internal magnetic pole, arranges hush panel again, just in groove
The defect for flying out and bringing as magnetic piece is broken can be prevented.
The content of the invention
It is an object of the invention to disclose a kind of in rotary pole, prevent magnetic piece fragment stuck mouth-sealing method, solve
In weight permanent magnetism suspension, outer magnetic pole is by the stuck problem of magnetic piece fragment, to ensure that internal magnetic pole is reliably rotated in the endoporus of outer magnetic pole.
To reach above-mentioned purpose, the technical solution used in the present invention is as follows.
Internal magnetic pole can be rotated in the hole of outer magnetic pole, and when a certain position is rotated to, internal magnetic field self can form envelope
Loop circuit, at this moment device is in erasing state；And when another location is rotated to, internal magnetic field self can not be formed and be closed back
Road, at this moment device is in upper magnetic state.Internal magnetic pole is namely rotated, device can be made to realize upper magnetic and demagnetization function.
Internal magnetic pole hush panel is not filled in the internal magnetic pole of Lifting Permanent Magnetic Crane in the past, is mostly that Bian machineries are riveted tightly, riveting
Tightly, certain impulsive force of riveting tightly will be produced, due to the similar ceramics of neodymium ferromagnetic block it is very crisp, under these impulsive forces, it is more likely that
Some local are just broken, are easy to the hole that magnetic piece fragment overflows and is stuck between interior outer magnetic pole occur later in use
It is interior, internal magnetic pole is prevented from continuing rotation, so that hoisting permanent magnet disabler.
In the method, as a sulculus has been opened on internal magnetic pole, hush panel can be set, then just need not be with machinery
Rivet tightly magnetic piece, need to only fix the envelope hush panel impulsive force that so avoids to rivet tightly and magnetic piece is caused to damage, so as to avoid possibility
Some local magnetic piece are broken, ensured the reliable rotation of internal magnetic pole, it is ensured that the performance of product.

Accompanying drawing is briefly described.
Fig. 1 is the general illustration of interior outer magnetic pole.
Fig. 2 is the schematic diagram of outer magnetic pole.
Fig. 3 is the schematic diagram of internal magnetic pole.
Fig. 4 is the cut-away view of Fig. 3.
Fig. 5 is the sectional view of Fig. 3.
Fig. 6 is the enlarged drawing of the magnetic pole 4 in Fig. 5.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described.
Internal magnetic pole 1 is provided with the endoporus of outer magnetic pole 2；Internal magnetic pole 1 is by groups such as spindle nose 3, magnetic pole 4, hush panel 5, permanent magnets 6
Into.Spindle nose 3 is arranged on the end of magnetic pole 4, and hush panel is arranged on the notch of magnetic pole 4, and permanent magnets 6 are arranged on magnetic pole 4 with sealing
In the space that plate 5 is surrounded.
Internal magnetic pole 1 can be rotated in the hole of outer magnetic pole 2, and when a certain position is rotated to, internal magnetic field self can be formed
Loop, at this moment device is in erasing state；And when another location is rotated to, internal magnetic field self can not be formed and be closed back
Road, at this moment device is in upper magnetic state.Internal magnetic pole is namely rotated, device can be made to realize upper magnetic and demagnetization function.
Internal magnetic pole hush panel is not filled in the internal magnetic pole of Lifting Permanent Magnetic Crane in the past, is mostly that Bian machineries are riveted tightly, riveting
Tightly, certain impulsive force of riveting tightly will be produced, due to the similar ceramics of neodymium ferromagnetic block it is very crisp, under these impulsive forces, it is more likely that
Some local are just broken, are easy to the hole that magnetic piece fragment overflows and is stuck between interior outer magnetic pole occur later in use
It is interior, internal magnetic pole is prevented from continuing rotation, so that hoisting permanent magnet disabler.
In the method, as a sulculus has been opened on magnetic pole 4, hush panel 5 can be set, then just need not be with machinery
Rivet tightly magnetic piece, need to only fix envelope hush panel 5 impulsive force that so avoids to rivet tightly and magnetic piece is caused to damage, so as to avoid possibility
Some local magnetic piece are broken, ensured the reliable rotation of internal magnetic pole, it is ensured that the performance of product.
