The dedicated off-chip aluminium casting machine of apparatus for cast-aluminium rotor of electric machine provided by the invention, as shown in Fig. 1 ~ Fig. 3, the apparatus for cast-aluminium rotor of electric machine
Dedicated off-chip aluminium casting machine includes: rack 1, main shaft 2, revolving platform 3 and driving mechanism 4；
The axis hole for running through 1 axis of rack is formed in the rack 1, the main shaft 2 is rotatably installed in the rack 1
In axis hole, and the upper end of the main shaft 2 is pierced by the axis hole upwards, and the lower end of the main shaft 2 is pierced by downwards described
Axis hole；Mounting hole is offered at the shaft core position of the revolving platform 3, the upper end of the main shaft 2 connects the mounting hole；Institute
Driving mechanism 4 is stated for driving the main shaft 2 to rotate, the rotation of the main shaft 2 is able to drive 3 turns of the revolving platform
It is dynamic.
It is understood that when the rotor to different size carries out cast aluminium operation, it is only necessary to install rotor
On the revolving platform 3, then starter, so that driving mechanism 4 drives the main shaft 2 to rotate, main shaft 2 turns
It is dynamic that revolving platform 3 is driven to rotate, so that rotor rotates；Since the main shaft 2 can generate radial work in rotation
Firmly, so that the concentricity of main rovolving shaft not can control, therefore cause cast aluminium is non-uniform to happen；The circular cone rolling
Sub- bearing 5 can undertake the radial forces that main shaft 2 is generated in rotation, improve the centering precision of the main shaft 2
With revolution when concentricity, thus the cast aluminium process of rotor can stable and uniform carry out, improve cast aluminium after rotor quality.
In order to further such that rotor cast aluminium process can stable and uniform carry out, mounting hole in 3 lower surface of revolving platform
Periphery is equipped with a circle and balances step 310, is equipped with plane bearing 6 between 1 upper surface of rack, under the balance step 310
Surface covers on the plane bearing 6.The structure can reduce the weight born on main shaft 2, improve the main biography
The stability of moving axis 2 and revolving platform 3 in rotation, is conducive to the stability and uniformity that improve the cast aluminium process of rotor.
Lubricating grease when revolving platform 3 runs at high speed in plane bearing 6 can be thrown away, and the grease thrown away can pollute revolving platform 3,
Therefore oil baffle 7 is equipped in 6 periphery of plane bearing.The oil baffle 7 can be to prevent 1 revolving platform 3 when running at high speed,
The lubricating grease being added in plane bearing 6 is thrown away.
There is imbalance during rotation in the main shaft 2 in order to prevent, in the axis hole close to the axis hole upper end
Hole wall is equipped with self-aligning bearing 8, and the self-aligning bearing 8 is set on the main shaft 2.Even if main transmission during operation
Axis 2 is slightly a little uneven, can also be adjusted and make up by self-aligning bearing 8, to achieve the purpose that balance.
Due to the weight difference of the rotor of different size, if revolving speed one of the rotor of different size during cast aluminium
Sample, the abundance that inevitably resulting in cast aluminium rate has have inadequate, to bring very big influence to cast-aluminum rotor total quality.Cause
The lower end of this main shaft 2 is equipped with big pulley concial disk 9 after being pierced by the axis hole；The driving mechanism 4 includes driving
Motor 410 is equipped with small pulley concial disk 420, small 420 He of pulley concial disk on the output shaft of the driving motor 410
V belt 10 is connected between big pulley concial disk 9.The driving motor 410 uses frequency converting speed regulating three-phase asynchronous electromotor, institute
Stating frequency converting speed regulating three-phase asynchronous electromotor cooperates the belt transmission main shaft 2 of three cuticles available and different size workpiece weight
The revolving speed to match, while while overloading, is protected, and facilitates plant maintenance.
In order to facilitate the movement that rack 1 is whole, the rack 1 is equipped with hanging ring 11.
In order to facilitate maintenance, and mitigate the overall weight of rack 1, offers service ports 12 in the middle part of the rack 1, it is described
Service ports 12 extend radially outwardly from the axis hole location, to reduce its processing cost, and facilitate installation and debugging.
It should be understood by those ordinary skilled in the art that: the above is only a specific embodiment of the present invention, and
It is not used in the limitation present invention, all any modification, equivalent substitution, improvement and etc. within purport of the invention, done should all include
Within protection scope of the present invention.
