Height, the various requirements at the higher level constantly proposed with correspondence all trades and professions, manufacturer are it has to be ensured that processing and manufacturing precision disclosure satisfy that
Customer requirement, while also to reduce product fraction defective is minimized production cost.
Because the diastema of current motor is the tradition come what is calculated by copper ring location dimension (distance of copper ring to commutator)
Technique processing mode influenceed by the dimensional tolerance of iron core Ka Simei dimensional tolerances and axle, its motor production in sham and axle go out
Precision is very unstable, makes the higher DC micromotor of technological requirement even in same production line, quality is also uneven, production
Product qualification rate is generally relatively low.
The content of the invention
In order to overcome the deficiencies in the prior art, work is entered it is an object of the invention to provide a kind of positioning of copper ring and commutator group
Skill, benchmark, then pressing-in commutator are used as by being first pressed into copper ring in battery core press-fitting step, solve prior art motor false
And axle goes out the problem of fluctuating big.
The purpose of the present invention is realized using following technical scheme：
(1) it is pressed into copper ring：According to iron core size, regulate mould on press-in device and push after stroke, copper ring is placed to pressure
Enter the lower mould of device, and the fixation overlapping with the mould recess hole center of circle under press-in device of the copper ring center of circle；
(2) copper ring is placed in mould under press-in device, motor shaft one end of iron core is resisted against copper ring center, the motor shaft of iron core
The other end is resisted against mould on press-in device；
(3) start press-in device, pressure is applied to the motor shaft other end of iron core by mould on press-in device, will be in pressure
Enter the motor shaft other end that the copper ring under device on mould is pressed into iron core, then take out the iron core after press-in copper ring；
(4) pressing-in commutator：Commutator is placed to the lower mould of press-in device, and commutator axis hole center is directed at press-in
The mould recess hole center of circle under device；
(5) mould on press-in device is changed, by original upper mould, mould on the axis hole with through hole groove is replaced with；
(6) through hole of mould on axis hole is fixed in motor shaft one end that iron core has been pressed into the iron core of copper ring, by copper ring sticker
With mould on axis hole；
(7) start press-in device, using copper ring as benchmark, the motor shaft of iron core one end is applied by mould on axis hole and pressed
Power, the commutator of the mould under press-in device is pressed into the motor shaft other end of iron core.
It is preferred that, in step 2, the motor shaft of iron core is respectively perpendicular to the upper die and lower die of press-in device.
It is preferred that, after mould is installed on the axis hole in step 5, the through hole center of circle of mould and lower mould recess hole center of circle weight on axis hole
Close.
It is preferred that, in step 6, the motor shaft of iron core is respectively perpendicular to the axis hole upper die and lower die of press-in device.
Compared with prior art, the beneficial effects of the present invention are：
In iron core press-in technique in motor fabrication process, copper ring is first pressed into, is pressed again by the use of copper ring as positioning datum
Enter commutator, make the high motor of craft precision requirement false in process of production and axle to go out fluctuation smaller, greatly reduce production
During bad products occur probability, so as to improve the precision and dimensional stability of finished product motor, improve the life of enterprise
While producing efficiency, production cost is also saved.

Embodiment
Below, with reference to accompanying drawing and embodiment, present invention process method flow is as follows：
A kind of copper ring positioning and commutator group enter technique, and the process flow is as follows
(1) it is pressed into copper ring 3：According to the size of iron core 4, regulate mould 1 on press-in device and push after stroke, copper ring 3 is placed
To the lower mould 2 of press-in device, and the fixation overlapping with the recess hole center of circle of mould under press-in device 2 of the center of circle of copper ring 3；
(2) copper ring 3 is placed in mould 2 under press-in device, motor shaft one end of iron core 4 is resisted against the center of copper ring 3, iron core 4
The motor shaft other end is resisted against mould 1 on press-in device, during process implementing, and iron core 4 is placed on copper ring 3 and press-in device
Between mould 1, or the wherein one end motor shaft of iron core 4 is fixed on mould 1 on press-in device, motor shaft is overlapped with the center of circle of copper ring 3；
(3) start press-in device, pressure is applied to the motor shaft other end of iron core 4 by mould on press-in device 1, will be in
Copper ring 3 under press-in device on mould 2 is pressed into the motor shaft other end of iron core 4, then takes out the iron core 4 after press-in copper ring 3；
