Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
The embodiment of a part of the invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
In a specific embodiment of the invention, the rotor 30 of magneto is to be laminated on by multiple rotor punchings 20
The rotor core formed together, the center of rotor core are axis hole.Rotor punching 20 has round sheet ontology 5, rotor core
It is equipped with the magnet slot 7 that multiple groups are circumferentially evenly arranged.Multiple connecting holes are equipped in the inside of the outer side magnet slot 7 of above-mentioned axis hole
6.Specifically, as shown in figure 3, by taking six pole rotor as an example, magnet slot 7 is in substantially open V-arrangement, and v-shaped opening is outwardly.Connecting hole 6
For screw mounting hole corresponding with the bottom of magnet slot 7.
Baffle 10 is located at the outside of rotor 30, as shown in Figure 2, it is preferable that baffle 10 has identical with rotor punching 20
Internal-and external diameter.At least two through slots 4 are evenly distributed in the circumferential direction along the ontology 1 of baffle 10.Through slot 4 it is corresponding with magnet slot 7 and
The shape that magnet 8 passes through is constructed so that, for example, through slot 4 is rectangle when magnet 8 is strip, and the length and width of through slot 4
Degree is all larger than the length and width of magnet 8.It is readily appreciated that, the shape of through slot 4 can be any, as long as magnet 8 can be allowed to pass through
?.In this embodiment, through slot 4 be six groups be substantially in eight shape strip-shaped hole.Above-mentioned two by magnet slot and logical as a result,
Slot composition is substantially in hexagonal structure, can rotation with baffle relative to rotor punching, and overlapping alignment or intersect wrong
It opens.
In a specific embodiment, as shown in Fig. 2, every group of through slot 4 is made of two strip holes.Thus, it is possible to
Place two magnets 8.The group number of through slot 4 and the number of poles of rotor match, for example, through slot 4 is set for six pole rotor
Six groups are set to, 12 pieces of magnets 8 can be placed.
In order to make baffle 10 that can be equipped with guide portion 3 on baffle 10 relative to rotor punching 20 with coaxial rotating.It is preferred that
Ground, guide portion 3 are at least two curved openings centered on the axis of rotor core.As shown in Fig. 2, guide portion 3 is arranged to 5
It is a, and when baffle 10 and 20 co-axially align of rotor punching, 5 connecting holes 6 on rotor punching 20 can just draw with 5
The alignment of portion 3 is led so that connector 6 ' can pass through.In addition, above-mentioned connecting hole 6 can be with baffle 10 relative to rotor punching 20
Rotation and move to the other end along one end of guide portion 3.Preferably, the both ends of arc guide portion 3 are provided in round or rectangular,
It is preferably circular.Thus, it is possible to be limited to connector 6 '.
When rotor punching 20 and 10 co-axially align of baffle, connector 6 ' can pass through connecting hole 6 and guide portion 3 for rotor
Punching 20 is flexibly connected with baffle 10.In this case, butterfly 10, connector 6 ' is along guide portion 3 from the first limiting section A
It skids off and is moved to the second limiting section B stopping, as shown in Figure 4 and Figure 5, since the positional relationship of guide portion 3 and through slot 4 can be true
Through slot 4 is protected just to rotate to the position being aligned with magnet slot 7.Thus, it is possible to carry out magnetic into rotor punching 20 through baffle 10
The assembly of body 8.When magnet 8 after the assembly is completed, opposite direction butterfly 10, connector 6 ' is sliding from the second limiting section B along guide portion 3
Out and it is back to the first limiting section A stopping, being staggered at this point, through slot 4 intersects with magnet slot 7, and then stop the outer bullet of magnet 8.
In a specific embodiment of the invention, as shown in Figure 4 and Figure 5, fixation hole 2 is additionally provided on baffle 10.
Preferably, the pole embrace that the distance between guide portion 3 of fixation hole 2 and curved opening shape is 0.3 to 0.7 times, more preferably
0.4 to 0.6 times of pole embrace.As shown in Fig. 2, pole embrace indicates the edge (semicircle) of fixation hole 2 and arc guide portion 3
Positional relationship.The purpose for limiting pole embrace is in order to control the rotatable angle of arc guide portion 3, for example, arc guides
Portion 3 can be set to 30 °, may be set to be 40 °, as long as magnet steel can be prevented to pop up.
Thus, it is possible to magnet 8 after the assembly is completed, opposite direction butterfly 10, when connector 6 ' is along guide portion 3 from second
The connecting hole 6 above fixation hole 2 and rotor punching when limiting section B is skidded off and is back to the first limiting section A stopping, above baffle
Just it is aligned.Further, it is mounted on fixation hole 2 and connecting hole 6 by locking piece, rotor punching 20 and baffle 10 is locked
It is fixed, to guarantee that baffle 10 can not rotate.
Simple illustration is carried out to the assembly method of magneto below.Firstly, as shown in Figures 2 to 7, by baffle 10 with
The two is flexibly connected by 20 co-axially align of rotor punching by connector 6 '.Later, butterfly 10 is to through slot 4 and magnet slot 7
After alignment, urgent connector 6 '.Magnet 8 is assembled into the magnet slot 7 of rotor punching 20 through the through slot 4 on baffle 10, later
Unclamp connector 6 '.Baffle 10 is reversely rotated to be staggered with magnet slot 7 to through slot 4 so that magnet 8 can not pop up, at this point, baffle
Fixation hole 2 on 10 is aligned with the connecting hole 6 on rotor punching 20, again urgent connector 6 '.Preferably, connector is screw
And cooperate including head of screw and screw pole, screw pole and curved opening, the outer diameter of head of screw is greater than the outer diameter of screw pole.Finally,
Fixing piece is mounted on fixation hole 2 to lock baffle 10 and rotor punching 20 in connecting hole 6.
In conclusion the present invention by the way that through slot 4 and guide portion 3 are arranged on motor baffle 10, can guarantee that magnet 8 can be with
Rotation of the baffle 10 relative to rotor punching 20, and be successfully packed into and be blocked in rotor punching 20.Compared with prior art,
Baffle 10 and rotor punching 20 can be directly first connected by screw to by assembly method of the invention, be assembled without waiting for magnet 8
Knockout screw installs baffle 10 again after the completion, therefore reduces installation step.
Although by reference to preferred embodiment, invention has been described, the case where not departing from the scope of the present invention
Under, various improvement can be carried out to it and can replace component therein with equivalent.Especially, as long as there is no structures to rush
Prominent, items technical characteristic mentioned in the various embodiments can be combined in any way.The invention is not limited to texts
Disclosed in specific embodiment, but include all technical solutions falling within the scope of the claims.
