Abstract
The present invention discloses a kind of permanent-magnet synchronous variable-frequency electric machine rotor dress pressure tire, including lower tire, threaded hole is arranged on the lower tire, screw rod lower end screws in the threaded hole, and the upper end of screw rod wears the centre bore of tire；The top of screw rod is fixed with hanging ring；Internal expanding core, ringfeder and positioning tube are set gradually outside the screw rod；The face that the internal expanding core, ringfeder abut against is the conical surface, and the upper thickness of internal expanding core is greater than lower part thickness, and ringfeder is then opposite；Punching is arranged at the annulus between ringfeder and positioning tube, along axially stacked setting；The upper end of insertion groove lining bar in the locating slot of punching, the slot lining bar is set in the through-hole of tire.The invention has the advantages that being the conical surface due to using the face that internal expanding core, ringfeder abut against, ensure that internal expanding core gradually radially elapses ringfeder in this way, not will cause punching it is mobile simultaneously when as location conflicts and caused by punching deformation；In addition, being also convenient for the disassembly of mould, the defect of straight barrel type internal expanding core is overcome.
Description
Technical field
The present invention relates to machinery field, specifically a kind of mould of motor rotor punching sheet.
Background technique
Permanent magnetic electric machine rotor iron core punching uses 1/2 closed assembly, and every 10 are a full circle, existing to guarantee the neat of punching
Technology generally uses slot lining bar to be set in the location hole of punching, and shaping is carried out on press machine, and this method positioning is inaccurate.
Summary of the invention
In order to solve the above-mentioned technical problem, guarantee that concentricity, the present invention use outer press mounting and interior press fitting two ways.With punching
Piece inner circle is benchmark face, and punching is stacked on swollen tire, and there are two slot lining bars on every fragment to position, and the uniformity of flute profile leans on
Slot lining bar guarantees that the uniformity of punching outer circle guarantees that positioning tube is made of two valves by positioning tube, intermediate fixed with positioning pin
Position, blending bolt are tightened, easy disassembly.Specific technical solution is as follows:
A kind of permanent-magnet synchronous variable-frequency electric machine rotor dress pressure tire, including lower tire, are arranged threaded hole on the lower tire, under screw rod
End screws in the threaded hole, and the upper end of screw rod wears the centre bore of tire；The top of screw rod is fixed with hanging ring；The screw rod
Outside sets gradually internal expanding core, ringfeder and positioning tube；The face that the internal expanding core, ringfeder abut against is the conical surface, and internal expanding core
Upper thickness is greater than lower part thickness, and ringfeder is then opposite；Punching is arranged at the annulus between ringfeder and positioning tube, along axially stacked
Setting；The upper end of insertion groove lining bar in the locating slot of punching, the slot lining bar is set in the through-hole of tire.
The conical surface and the angle of vertical direction are 3-5 degree.
The upper tire setting compression platform, the compression platform are arranged at the annulus between ringfeder and positioning tube；Upper tire with it is hydraulic
The pressure head of machine is corresponding.
The initial position setting of ringfeder is higher than ringfeder in lower tire upper surface, the initial position of internal expanding core.
The invention has the advantages that due to using outer press mounting and interior press fitting two ways, and internal expanding core, ringfeder abut against
Face is the conical surface, ensures that internal expanding core gradually radially elapses ringfeder in this way, when not will cause punching while movement
The deformation of punching caused by as location conflicts；In addition, being also convenient for the disassembly of mould, the defect of straight barrel type internal expanding core is overcome.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the top view of Fig. 1.
Specific embodiment
The present invention is illustrated with reference to the accompanying drawing, and as shown in Figure 1 and Figure 2, the present invention includes lower tire 1, is set on the lower tire
Threaded hole is set, 2 lower end of screw rod screws in the threaded hole, and the upper end of screw rod 2 wears the centre bore of tire 3；The top of screw rod
It is fixed with hanging ring 4；Locking nut 5 is also set up above screw rod；Internal expanding core 6, ringfeder 7 and positioning are set gradually outside the screw rod
Cylinder 8；The face 10 that the internal expanding core 6, ringfeder 7 abut against is the conical surface, and the upper thickness of internal expanding core is greater than lower part thickness, and is risen
Then on the contrary, being can guarantee in this way when upper tire pushes internal expanding core 6, ringfeder 7 is gradually radially outer to be moved set, avoids the same time shift of excessive punching
When dynamic as location conflicts and caused by deform；Punching 9 is arranged at the annulus between ringfeder 7 and positioning tube 8, sets along axially stacked
It sets；The upper end of insertion groove lining bar 11 in the locating slot of punching, the slot lining bar is set in the through-hole of tire.
The conical surface 10 and the angle of vertical direction are 3-5 degree.
The upper tire setting compression platform 12, the compression platform 12 are arranged at the annulus between ringfeder and positioning tube；Upper tire with
The pressure head of hydraulic press is corresponding.
The initial position setting of ringfeder is higher than ringfeder in lower tire upper surface, the initial position of internal expanding core.
