Cooperation；Platen is installed, the stator positioning spigot of the platen periphery and the upper end of piece stator cooperate on the core model.
The base center passes through compression bar bolt, and the compression bar bolt installs upper limit spiral shell after the centre bore of platen
Mother, the upper limit nut external welding lifting lug.
The lower location nut being also equipped on the compression bar bolt below platen；Lightening hole is provided on the platen.
In use, first lying in the piece tooling base for penetrating compression bar bolt on assembly jig, piece tooling core model is put
On piece tooling base, the two is cooperated by core model positioning spigot, stator bottom plate is placed on the boss of pedestal outer ring；It will
First piece stator is put on stator bottom plate, and piece stator inner ring and piece tooling core model outer circle cooperate, stator lower end surface
Cooperated by the stator positioning spigot of piece tooling base central boss；The axial notch that is successively opened up on piece stator and
The assembled remaining N-1(N=number of slots of axial double wedge) a piece stator；Lower position nut is screwed into pressure first after the completion of assembled
The thread root of bar bolt, then platen is penetrated into compression bar bolt, stator positioning spigot and piece stator upper end to platen edge
After face is worked good, upper limit nut is tightened, then by the lightening hole on platen, is extend into below platen, then by lower limit spiral shell
Mother is screwed onto the lower end surface of platen, plays the role of fixed platen, to guarantee stator piece impaction state；By the axis on piece stator
Nut on screw rod successively unclamps, and axial screw is extracted out；Stator upper head plate is put, then axial screw is set up, tightens spiral shell
Mother completes the assembly of entire stator.
The more current stator assembling technique of magneto piece stator assembling is shortening the production cycle and is improving product
Can on have very big advantage.It has the advantage that compared with prior art as follows:
1, magneto piece stator splicing accuracy is improved, the insulation harm of motor is reduced.
2, it the production cycle for shortening assembled stator piece, improves work efficiency.
3, the labor intensity of worker is reduced.
After magneto piece stator assembling, it is ensured that the internal-and external diameter tolerance satisfaction after stator assembly is got up is set
Meter requires, to guarantee that magneto air gap reaches design requirement, and meets the build-up tolerance of permanent magnet motor stator and shell.
