Description
Technical field
The present invention relates to rotor turnery processing fields, more specifically, are 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 technique
Currently, the rotor on low-power machine, generally wants size, to guarantee the same of outer circle of motor rotor and armature spindle
The circularity of heart degree and itself.After rotor assembly after turning, it is ensured that turn, the air gap between stator more should all, it is right
There is apparent effect in noise, the vibration etc. of the entire motor of inhibition, it is seen that the turning of outer circle of motor rotor is essential
One of manufacturing procedure, but turnery processing can inevitably generate the iron filings of splashing, these iron filings vary, and what is had will
It flies on the load bearing of rotor, can thus destroy the finish on armature spindle surface, the quality of rotor is generated
It influences, does not only result in general assembly assembly difficulty, also will increase the noise of motor.
As shown in Figure 1, drive belt component for existing rotor truning fixture is lifted up, with rotor
Rotor core is detached from, and is not driven power by the rotor that armature spindle is mounted on the load bearing of two sides at this time；And
As shown in Fig. 2, the turning state of cylindrical turning, drive belt component pressure are carried out to rotor for electronics rotor truning fixture
Under, the rotor core of rotor is pushed down, rotor rotation is driven, and the point of a knife of cutter is fed into forward cutting position, at this moment exists
During turning, point of a knife can sputter many iron filings, and a part in iron filings can splash on load bearing, and due to load
The surface hardness of bearing is more much higher than the hardness of armature spindle, so that armature spindle surface can be destroyed, its surface is wiped and is spent, and armature spindle
Surface is wiped spend after, will affect motor general assembly, i.e. armature spindle cannot pack into bearing, although some wipe Hua Bushi it is very serious
Can pack into bearing, but will cause noise.
