Description
Technical field
The present invention relates to rotor turnery processing field, more specifically, it is related to a kind of carrying of rotor turning
Device, a kind of rotor truning fixture and a kind of rotor method for turning.
Background technology
At present, the rotor on low-power machine, typically wants size, to ensure the same of outer circle of motor rotor and armature spindle
Heart degree and the circularity of itself.After rotor assembling after turning it is ensured that turn, the air gap between stator more all should, right
There is obvious effect in suppressing noise, vibration of whole motor etc. it is seen that the turning of outer circle of motor rotor is requisite
One manufacturing procedure, but turnery processing inevitably can produce the iron filings of splashing, and these iron filings vary, and have will
Fly to the fineness that armature spindle surface thus can be destroyed on the load bearing of rotor, the quality of rotor is produced
Impact, does not only result in general assembly assembling difficulty, also can increase the noise of motor.
As shown in figure 1, being lifted up and rotor for the driving belt assembly of existing rotor truning fixture
Rotor core departs from, and is not driven power now by the rotor that armature spindle is mounted on the load bearing of both sides；And
As shown in Fig. 2 rotor is carried out for electronics rotor truning fixture with the turning state of cylindrical turning, driving belt assembly pressure
