Description
Technical field
This utility model relates to wind-driven generator assembling field, it is provided that a kind of rotor core end plate positioning tool, is used for
When rotor core end plate is set on punching iron core, rotor core end plate is accurately positioned on punching iron core, with ensure end plate bore with
The centre-to-centre spacing in stretching screw hole is within the scope of technological requirement, the offset deviation of end plate groove and rotor slot is in technological requirement
Within the scope of.
Background technology
One typhoon power generator rotor core comprises 2 pieces of identical rotor core end plates.Rotor core end plate is that wind-force is sent out
The vitals of electric machine rotor iron core, it for being compacted into an entirety, rotor core end plate by iron-core lamination and ventilation channel plate
Assembling quality the quality of finished product rotor is had a significant impact.
Shown in Figure 1, iron-core lamination 1 is the thin slice flange arrangement of hollow, the uniform punching in periphery circumferential teeth 101, accordingly
The uniform punching in periphery groove 102；Iron-core lamination 1 is gone back stamping-out have along uniform 6 the punching through holes 103 of pitch circle.
The most shown in Figure 2, wind power generator rotor core end plate 2 is the flange arrangement of hollow, and periphery is uniform and punching
The end plate circumferential teeth 201 that circumferential teeth 101 is corresponding, the uniform end plate groove 202 corresponding with punching groove 102 in corresponding periphery；?
It is further opened with on flange along uniform 6 the end plate through holes 203 corresponding with punching through hole 103 of pitch circle.
The technique of experience, the aperture of end plate through hole 203 should be greater than the aperture of punching through hole 103.
The most shown in Figure 3, if dry tablet iron-core lamination 1 tires out poststack and forms rotor punching iron core 3, if dry tablet iron-core lamination 1
Punching through hole 103 corresponding, formed for using the tension of rotor punching core pressing with the stretching screw of insulating barrier
Screw hole 301.If the punching groove 102 corresponding formation rotor slot 302 of dry tablet iron-core lamination 1, the notch of rotor slot 302 and
Slot bottom width is equal, therefore punching groove 102 is rectangular channel.
Follow-up rotor bar rolls off the production line in operation process, for bar and the insulating barrier of stretching screw requirement of shelter relatively
Height, has less displacement between iron-core lamination, can be made up by follow-up dipping lacquer, be revised, have bigger shifting between iron-core lamination
Position, follow-up dipping lacquer can not make up, when revising, although allow the insulating barrier of bar and stretching screw to have certain elastic deformation,
It is also possible to the insulating barrier of bar and stretching screw is caused damage.Therefore, end plate circumferential teeth 201 is straight-tooth, accordingly, and end plate groove
102 is T-slot, for avoiding wind power generator rotor core end plate 2 to interfere with rotor bar, and end plate groove 202 bottom land relatively punching groove
102 bottom lands are wider than punching groove 102 bottom land width closer to rotor axis, end plate groove 202 bottom land, it is clear that end plate groove 202 slot opening
More than punching groove 102 slot opening.
In prior art, if the installation method of wind power generator rotor core end plate is dry tablet iron-core lamination 1 tires out poststack, will
Wind power generator rotor core end plate is placed on the iron-core lamination of tired poststack, and operator, by range estimation, manually adjusts it relative
In iron-core lamination position, then compression tooling and stretching screw are installed and compress iron core.
This mode manually adjusted will produce problems with:
1, artificial range estimation adjustment is more difficult accurately determines wind power generator rotor core end plate accurate location on circle,
The phenomenon of local location skew can be there is；
2, end plate position all may be made to offset during subsequent installation compression tooling and compression iron core；
3, inefficiency, needs 2-3 people to operate, waste of manpower simultaneously.
Aforementioned 1, the reason of 2 two, the skew of wind power generator rotor core end plate position may cause stretching screw to insulate
Layer and rotor bar insulating barrier are damaged, it is more difficult to meet technological requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of rotor core end plate positioning tool of a kind of offer, for unshakable in one's determination in punching
On rotor core end plate is accurately positioned on punching iron core, to ensure end plate bore and stretching screw time rotor core end plate is set
The centre-to-centre spacing in hole is within the scope of technological requirement, the offset deviation of end plate groove and rotor slot technological requirement scope it
In.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of rotor core end plate positioning tool, including multiple identical for the stretching screw hole on punching iron core being
