Abstract
The invention discloses a method for rapidly positioning penetrating screw rod holes of a generator motor stator. The method comprises the steps: mounting big equalization positioning ribs; stacking up stator punching plates; adjusting the uniformity of the stator punching plates and checking notch grinding situations of the stator punching plates; assembling a penetrating screw rod sample plate, making mark points and punching holes. In the method, the stator punching plates are stacked up in a half overlapping method; the stacked stator punching plates are positioned with a positioning bolt and used as a penetrating screw rod hole sample plate; the penetrating screw rod hole sample plate is assembled for positioning the stator; the penetrating screw rod hole sample plate is dismounted and then the stator is punched; and the penetrating screw rod hole sample plate can be repeatedly used to position the stator. The method for rapidly positioning the penetrating screw rod holes of the generator motor stator has the advantages of small amount of positioning work, high positioning efficiency and accurate positioning; the secondary washing and the secondary storage of the stator punching plates can be avoided.
Description
Technical field
The present invention relates to a kind of localization method of electricity generation and electromotion machine stator core through screw rod hole, particularly a kind of can the electricity generation and electromotion machine stator core through screw rod hole localization method of quick position.
Background technology
At present, the installation key step of the generator motor stator core in hydroenergy storage station is: out frame group circle, the welding of support combinated seam, central cyclometric stand installation, support center and horizontal adjustment, positioning bar installation, core through screw rod hole machined, stator punching are stacked into stator core, core through screw rod compression stator core and cores-loss test and finally check and accept, wherein core through screw rod hole machined is the accurate location needing first to carry out core through screw rod hole site, so that stator core heap poststack core through screw rod correctly can compress stator core.
Now conventional electricity generation and electromotion machine stator core through screw rod hole localization method is: it is stacking first to carry out wholecircle stator punching, and stack thickness is the thickness of 10 stator punchings; Mark a little according to the position of opening on stator punching with sample punching on the lower ring plate of out frame again; Then the stator punching that is all stacked is removed, and according to the position perforate of gauge point, as core through screw rod hole.There is the repetition operation process that stator punching wholecircle heap poststack is removed again in this localization method, workload is large, location efficiency is lower; And after having located, also there is the problem needing secondary cleaning and secondary to preserve in stator punching.Therefore, existing electricity generation and electromotion machine stator core through screw rod hole localization method also exists the problem that positioning work amount is large, location efficiency is lower and stator punching needs secondary cleaning, secondary to preserve.
Summary of the invention
The object of the invention is to, a kind of electricity generation and electromotion machine stator core through screw rod hole localization method is provided.The present invention can not only reduce positioning work amount, improves location efficiency, can also avoid the advantage that the secondary cleaning of stator punching, secondary are preserved.
Technical scheme of the present invention: electricity generation and electromotion machine stator core through screw rod hole method for rapidly positioning, comprises the following steps:
A, large equal dividing and positioning muscle is installed, the supporting plate of fixing large equal dividing and positioning muscle is radially from inside to outside welded on every layer of ring flat-plate of out frame;
B, with length be full circle girth 1/10 chord length be as the criterion, adopt the stacking stator punching of 1/2nd splicing processes, stack thickness is the thickness of 10 stator punchings, and with alignment pin location, as core through screw rod hole model;
C, dressing stick is inserted in stator punching notch in adjust the regularity of stator punching in the model of core through screw rod hole, groove rod is inserted in the notch of stator punching and checks that the radial and circumference of the notch confirming stator punching is all without grinding one's teeth;
D, on the model of core through screw rod hole, stamp rivet, make stator punching become as a whole;
E, by tight for the dovetail slot contract on the bayonet socket on the model of core through screw rod hole and large equal dividing and positioning muscle, core through screw rod hole model and large equal dividing and positioning muscle are accurately assembled, re-use sample punching marks a little according to the position of opening on stator punching, as core through screw rod hole datum mark on the lower ring plate of out frame;
F, dismounting core through screw rod hole model, in the position perforate of core through screw rod hole datum mark, as core through screw rod hole.
In the method for rapidly positioning of aforesaid electricity generation and electromotion machine stator core through screw rod hole, the large equal dividing and positioning muscle in described step a be out frame lower ring plate on 10 by full circle ten decile and all good positioning bar of linearity and torsion resistance.
In the method for rapidly positioning of aforesaid electricity generation and electromotion machine stator core through screw rod hole, the stacking stator punching of employing 1/2nd splicing processes in described step b is, carries out stacking by adjacent bed two panels stator punching along 4 slot pitches that stagger clockwise or counterclockwise.
Compared with prior art, present invention improves over the localization method in electricity generation and electromotion machine stator core through screw rod hole, by the stacking stator punching of 1/2nd splicing processes, avoid wholecircle stator punching stacking, location, the core through screw rod hole stator punching quantity of more than 90% can be saved, reduce positioning work amount, improve location efficiency; By the stator punching of alignment pin location heap poststack, as core through screw rod hole model, as long as not only remove core through screw rod hole model just can carry out perforate when perforate, can also reuse when next time locates, reduce by the stator lamination stacking of more than 90% and remove workload, reducing positioning work amount further, improve location efficiency; And core through screw rod hole model can not only be reused, and can also integrally preserve; Can not only make the location in core through screw rod hole more fast, accurately like this, the secondary cleaning of stator punching and secondary can also be avoided to preserve.Therefore, the present invention not only has that positioning work amount is little, location efficiency is high and the advantage of accurate positioning, and the secondary cleaning of stator punching and secondary can also be avoided to preserve.
Embodiment
Below in conjunction with embodiment, the present invention is further illustrated, but not as the foundation limited the present invention.
Embodiment.Electricity generation and electromotion machine stator core through screw rod hole method for rapidly positioning, comprises the following steps:
