Description
Technical field
The utility model is related to a kind of frock, more particularly to a kind of positioning tool of exciter stator pole core.
Background technology
The stator yoke ring of generator exciter is normally mounted at what generator end was covered, by generator's cover bearing chamber
The centre bore that circular hole is positioned as yoke ring.The radian at equal intervals after the completion of the assembling of stator yoke ring, it is necessary on the medial surface of yoke ring
10-18 single magnetic poles are installed on ground, and each magnetic pole is installed, due to the error in assembling process, frequently resulted in successively one by one
Magnetic pole circumferentially assembles uneven, causes magnetic pole and exciter rotor non-uniform air-gap, causes to sweep the generation of thorax phenomenon, seriously
Exciter rotor is also resulted in burn.Prior art controls magnetic pole to fill generally by pole assemblage fixture is set on yoke ring
With precision.Because magnetic pole is that silicon steel plate stacking is formed, outer ledge flatness is inconsistent, and the positioning precision of fixture is limited, still
So magnetic pole can not be overcome circumferentially to assemble uneven defect.
The content of the invention
The utility model provides a kind of exciter stator pole core positioning tool, solves generator excitation machine stator
Magnetic pole on yoke ring circumferentially assembles uneven technical problem.
The utility model is to solve above technical problem by the following technical programs：
A kind of exciter stator pole core positioning tool, including generator's cover, cover in generator end and are provided with hair
Motor bearing chamber circular hole lid, covers in generator end and is fixedly installed exciter stator and grips ring, dynamo bearing room circular hole lid is
It is arranged on exciter stator to grip on the center of circle of ring, the dynamo bearing room circular hole in exciter stator grips ring, which is covered, is provided with magnetic
Pole assembling centering tooling ring-type chassis, pole assemblage centering tooling ring-type chassis is that concentric is set with dynamo bearing room circular hole lid
Put, pole assemblage centering tooling ring-type chassis it is cylindrical on be positioned apart from brace rod, in horn-like brace rod
Pole assemblage is connected with to middle ring on the circle of upper end, and magnetic pole is provided with equal intervals on lateral surface of the pole assemblage to middle ring radian
Screens groove is assembled, pole core is provided between pole assemblage screens groove and exciter stator grip ring.
Pole assemblage centering tooling ring-type chassis is linked together by screw with dynamo bearing room circular hole lid.
The utility model is the pole assemblage positioning disk by first one entirety of component, in the outside of pole assemblage positioning disk
Magnetic pole locating slot is laid on face, overall pole assemblage positioning disk is integrally accurately located at into exciter stator grips in ring 3, from
And reach the purpose for being accurately positioned and installing magnetic pole.
The utility model ensure that whole magnetic pole once mounting in place, simplify operating process, thoroughly solve magnetic pole peace
The problem of non-uniform occurred in dress.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of overall pole assemblage positioning disk of the present utility model；
Fig. 3 is the fiting relation figure that dynamo bearing room circular hole lid 2 of the present utility model and exciter stator grip ring 3.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
A kind of exciter stator pole core positioning tool, including generator's cover 1, are provided with generator's cover 1
Dynamo bearing room circular hole lid 2, exciter stator is fixedly installed on generator's cover 1 and grips ring 3, dynamo bearing room circular hole
Lid 2 is provided in exciter stator and gripped on the center of circle of ring 3, on the dynamo bearing room circular hole lid 2 during exciter stator grips ring 3
It is provided with pole assemblage centering tooling ring-type chassis 4, pole assemblage centering tooling ring-type chassis 4 and dynamo bearing room circular hole lid
2 be concentric set, pole assemblage centering tooling ring-type chassis 4 it is cylindrical on be positioned apart from brace rod 5, in loudspeaker
Pole assemblage is connected with to middle ring 6 on the upper end circle of the brace rod 5 of shape, on lateral surface of the pole assemblage to middle ring 6 at equal intervals
Pole assemblage screens groove 7 is provided with radian, and magnetic pole is provided between pole assemblage screens groove 7 and exciter stator grip ring 3
Iron core 8.
Pole assemblage centering tooling ring-type chassis 4 is linked together by screw with dynamo bearing room circular hole lid 2.
The utility model is in use, only need pole assemblage centering tooling ring-type chassis 4 being positioned over bearing chamber circular hole lid 2
Interior, rotary tooling, the center line of screens groove 7 and the screwhole position on exciter stator yoke ring 3 for making pole assemblage is aligned, by magnetic pole
Iron core 8 is sequentially inserted into pole assemblage screens groove 7, you can complete the assembling of pole core.The magnetic pole iron assembled using this frock
Core, has fully met concentricity and the perpendicularity requirement of magnetic pole installation, and whole magnetic pole once mounting in place, is simplified and operated
Journey, it is ensured that product quality.
