Description
Technical field
The utility model belongs to the technical field of the motor manufacturing, particularly relates to a kind of external rotor electric machine assembling
Tooling.
Background technology
Common outer rotor motor structure drive end bearing bracket/rotor/stator etc. as shown in Figure 1, be mainly made of, under normal circumstances
All it is that stator is first fixed with drive end bearing bracket assembling, is reloaded into rotor later.The structure there are the problem of have：（1）Due to stator and turn
Air gap very little between son, when rotor assembles, the suction between magnet steel and stator core is bigger, and rotor can be drawn to one by this
Side can not complete rotor assembling, and especially Motor Shaft is shorter, and when rotor is longer；（2）I.e. enabled assembling reluctantly is got on, dress
Bearing may also can be damaged, and then reduce electrical machinery life with process；（3）Using the large-torque outer rotor motor of magnet, inhale
Power is big, and the situation of secundly is more prominent.
Invention content
To solve the above-mentioned problems, the utility model provides a kind of external rotor electric machine assembly tooling, the tooling stator and
Drive end bearing bracket fixes composition component, then refills dispensing rotor, bearing will not be damaged in assembling process.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
The utility model is a kind of external rotor electric machine assembly tooling, and including lower tooling and upper tooling, stator and drive end bearing bracket are consolidated
Front end cap assemblies are formed after fixed, front end cap assemblies are fixed on down by the first trip bolt, the second trip bolt and opening annulus
In tooling, in the bottom surface of upper tooling, there are four round magnet steel for setting, and when assembling rotor, rotor is attracted to the bottom of tooling,
Two guide rails between lower tooling and upper tooling are set, spring is equipped in the outer sheath of every guide rail, also divides on every guide rail
Pin is not provided with, is put into rotor in upper tooling, after the cap assemblies of lower tooling fixed stator front end, passes through the upper work of press pressure
Dress, rotor shaft slowly enter bearing, stop to suitable position.
Further improvement of the utility model is：First trip bolt is symmetrical arranged with the second trip bolt.
Further improvement of the utility model is：Two guide rails are symmetrical arranged.
The beneficial effects of the utility model are：（1）Simple and reliable for structure, two guide rails for being separated by 180 degree ensure work up and down
Two screws for partially, being separated by 180 degree will not be turned round between dress, ensure that stator front end cap assemblies are secured firmly in lower tooling；（2）Two
Root guide rail can ensure that rotor is concentrically assembled on motor, and assembling process will not damage bearing；（3）Lower tooling and stator front end
It screws by the annulus that is open, two screws between cap assemblies, is then fastened as a whole.

Specific embodiment
In order to deepen the understanding to the utility model, the utility model is done further below in conjunction with drawings and examples
Detailed description, the embodiment are only used for explaining the utility model, and the scope of protection of the utility model is not formed and is limited.
As shown in Figs. 1-5, the utility model is a kind of external rotor electric machine assembly tooling, including lower tooling 4 and upper tooling 8,
Stator 1 and drive end bearing bracket 2 form front end cap assemblies after fixing, the front end cap assemblies fasten spiral shell by the first trip bolt 7, second
Nail 6 and opening annulus 5 are fixed in the lower tooling 4, and there are four round magnet steel 9, assemblings for the bottom surface setting of tooling 8 on described
During rotor, rotor is attracted to the bottom of the upper tooling 8, and two guide rails are set between the lower tooling 4 and upper tooling 8
10, spring 11 is equipped in the outer sheath of the every guide rail 10, pin 12 is also respectively provided on the every guide rail 10, sells
Nail positioning, spring protection rotor will not damage bearing by quickly inhaling, rotor is put into tooling 8 on described, described
After lower 4 fixed stator front end cap assemblies of tooling, the upper tooling 8 is depressed by press, rotor shaft 13 slowly enters bearing, arrives
Suitable position stops, and first trip bolt 7 is symmetrical arranged with second trip bolt 6, ensures stator drive end bearing bracket group
Part is secured firmly in lower tooling, and two guide rails 10 are symmetrical arranged.Be separated by 180 degree two guide rails ensure up and down tooling it
Between will not turn round partially,
The magnet steel suction of tooling cannot be too big on the utility model, and suction is best to be slightly larger than rotor its own gravity；Before
End cap and fore bearing must use tight fit, and rotor shaft and motor front axle hold that tight fit is best, and loose fit then needs other auxiliary
Help measure.
This patent is particularly suitable for the external rotor electric machine of big outer diameter/big output power, big especially with magnet suction
Occasion.
