Abstract
A kind of easy-off magnetic pole box, comprises cover plate and base plate, cover plate and base plate all has bolt hole, respectively having one for dismantling the Bolt dismantling hole of magnetic pole box, having the screw thread for dismantling in Bolt dismantling hole in the centre position of base plate both sides.When being with the permanent magnet of magnetic pole box to break down to need to change, being not change permanent magnet separately, but whole magnetic pole box is changed.The utility model only need establish two threaded bolts hole newly on base plate just can realize quick, easy labour-saving again dismounting magnetic pole box.Establish threaded bolt hole newly not need to increase cost, and simple, so the utility model is suitable for applying.
Description
Technical field
The utility model relates to the improvement of magnetic pole box, is specifically related to the structure facilitating magnetic pole box to dismantle.
Background technology
Because magnetic pole box can well be fixed the permanent magnet in motor and protect, therefore permanent magnet is first loaded magnetic pole box and fixes and magnetic pole box be fixed by bolts on the support of rotor after magnetizing again by increasing motor.Because the magnetic pole box after magnetizing has very large magnetic, even if so magnetic pole box be arranged on rotor or mover support on take out bolt after, with hand, magnetic pole box is taken out also suitable effort from support.And if go to prize magnetic pole box with instruments such as bottle openers, then can due to very close to each other between the support of magnetic pole box and rotor and be difficult to realize.Do not find by domestic retrieval the patent having similarity with the utility model, how to realize the quick detachable research of still needing of magnetic pole box.
Utility model content
The technical problems to be solved in the utility model is: there is stronger magnetic attraction between the magnetic pole box of magneto and the rotor field spider of motor, not easily magnetic pole box taken out from rotor field spider, and propose a kind of Bolt dismantling hole of Simple detachable magnetic pole box.
Pin is with the problems referred to above, the technical scheme that the utility model proposes is: a kind of easy-off magnetic pole box, comprise cover plate and base plate, cover plate and base plate all have bolt hole, respectively having one in the centre position of base plate both sides for dismantling the Bolt dismantling hole of magnetic pole box, in Bolt dismantling hole, having the screw thread for dismantling.
Further, the both sides of the cover plate of magnetic pole box respectively have 3 bolts hole, and the both sides of the base plate of magnetic pole box also respectively have 3 bolts hole, and 6 bolts hole on base plate are all positioned at immediately below 6 bolts hole on cover plate.
Further, 6 bolts hole on cover plate are all do not have threaded level and smooth bolt hole, and 4 bolts at base plate two ends are also all do not have threaded level and smooth bolt hole.
Further, 2 bolts hole opened in the centre position of base plate both sides are Bolt dismantling holes, have the screw thread for dismantling magnetic pole box.
Further, the thickness of base plate is greater than 3 millimeters, Bolt dismantling hole is through base plate.
The utility model has the advantages that:
1. for dismantling the screw thread that the Bolt dismantling hole of magnetic pole box and the different of other bolt hole are only to have in Bolt dismantling hole for dismantling, so it is simple for opening Bolt dismantling hole on base plate;
2. on base plate, open Bolt dismantling hole need cost hardly, be suitable for applying;
As long as twist a few circle with screwdriver when 3. dismantling magnetic pole box, make magnetic pole box in the position in Bolt dismantling hole by bolt jack-up, there is gap in the rotor field spider of magnetic pole box and motor, coordinate bottle opener or straight screwdriver to stretch in described gap again magnetic pole box is levered up, take out can complete dismounting with hand again, adopt the utility model dismounting magnetic pole box quick, easy to be laborsaving again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is base plate stereogram of the present utility model;
In figure: 1 cover plate, 2 base plates, 31 Bolt dismantling holes, 32 level and smooth bolts hole, 4 glue, 5 permanent magnets.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the description of one step is done to the utility model:
Embodiment one
In the utility model, bolt hole be divide into two kinds, a kind of is the threaded Bolt dismantling hole 31 for dismantling, and one is threadless level and smooth bolt hole 32.As shown in Figure 1, when being with the permanent magnet 5 of magnetic pole box to break down to need to change, being not change separately permanent magnet 5, but whole magnetic pole box is changed.When magnetic pole box is installed, first cover plate 1 and base plate 2 are welded, load after permanent magnet 5 encapsulating 4 fill, carry out assigned direction to permanent magnet 5 to magnetize, due to the rotor of magneto or mover support having 4 bolts hole corresponding with the bolt hole at magnetic pole box two ends, as long as so on the rotor that just magnetic pole box can be fixed on magneto with 4 bolts or mover support.During dismounting magnetic pole box, first unclamp 4 bolts on fixed magnetic pole box, because the magnetic attraction between permanent magnet 5 and the rotor of motor or the support of mover is larger, so magnetic pole box is taken out the suitable effort of meeting from support with hand, and with the instruments such as bottle opener go sled magnetic pole box bottom, then can due to very close to each other between magnetic pole box and support and be difficult to realize.
For solving the problem, respectively establish a level and smooth bolt hole 32 newly in the centre position, cover plate 1 both sides of magnetic pole box, on described cover plate 1 increase 2 level and smooth bolts hole 32 in be do not have threaded.Respectively establish a Bolt dismantling hole 31 newly in the centre position, base plate 2 both sides of magnetic pole box in addition, on these 2 base plates 2, the Bolt dismantling hole 31 of increase is threaded.And immediately below level and smooth bolt hole 32 on 2 cover plates 1 being positioned at out of Bolt dismantling hole 31 on 2 base plates 2 of increase, but the backing positions immediately below Bolt dismantling hole 31 on 2 base plates 2 of increase does not open bolt hole.The thickness of base plate 2 is greater than 3 millimeters, preferred 3-5 millimeter, threaded Bolt dismantling hole 31 is through base plate 2.
During dismounting magnetic pole box, a bolt is put into any one Bolt dismantling hole 31 in 2 Bolt dismantling holes 31 on base plate 2, turn bolt with screwdriver, on the rotor that after a few circle of screws, motor can be pushed up in the front end of bolt or mover support.Continue to twist bolt, bolt will make to occur gap between base plate 2 and support, and bottle opener or straight screwdriver are put in gap and can magnetic pole box be levered up easily again.Magnetic pole box after levering up and the magnetic attraction between support reduce a lot, and hand well can capture magnetic pole box, and that now just can less require great effort with hand has taken out magnetic pole box.
Usual bolt coordinates for mounting part part with threaded bolt hole, but act in a diametrically opposite way in the utility model, bolt is coordinated with threaded bolt hole and dismantles magnetic pole box, and effect is fine, both the laborsaving efficiency turn improving dismounting, also can not damage magnetic pole box.
Obviously, under the prerequisite not departing from principle described in the utility model, the some improvement made or modification all should be considered as protection range of the present utility model.
