Abstract
The utility model discloses a kind of permanent-magnet synchronous variable-frequency electric machine rotor dress pressure tire, including lower tire, is threaded hole on the lower tire, screw rod lower end is screwed in the screwed hole, and the upper end of screw rod wears the centre bore of tire；The top of screw rod is fixed with suspension 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 more than bottom thickness, and ringfeder is then opposite；Punching is arranged at the annulus between ringfeder and positioning tube, is stacked vertically；Insertion groove lining bar in the locating slot of punching, the upper end of the groove lining bar are set in the through hole of tire.The utility model has the advantages that：The face abutted against as a result of internal expanding core, ringfeder is the conical surface, so ensures that internal expanding core progressively radially elapses ringfeder, will not cause punching and meanwhile it is mobile when due to location conflicts and caused by punching deform；In addition, be also convenient for the dismounting of mold, the defects of overcoming straight barrel type internal expanding core.
Description
Technical field
Mechanical field is the utility model is related to, specifically a kind of mold of motor rotor punching sheet.
Background technology
Permanent magnetic electric machine rotor iron core punching uses 1/2 closed assembly, and every 10 are a full circle, existing to ensure the neat of punching
Technology is typically set in the positioning hole of punching using groove lining bar, and shaping is carried out on forcing press, and this method positioning is inaccurate.
Utility model content
In order to solve the above-mentioned technical problem, concentricity is ensured, the utility model uses outer press mounting and interior press fitting two ways.
The face on the basis of punching inner circle, punching is stacked on swollen tire, per thering are two groove lining bars to position on burst, flute profile it is neat
Degree, ensure, the cylindrical regularity of punching is ensured that positioning tube is made up of two valves by positioning tube by groove lining bar, centre positioning
Finger setting, blending bolt are tightened, easy disassembly.Concrete technical scheme is as follows：
A kind of permanent-magnet synchronous variable-frequency electric machine rotor dress pressure tire, including lower tire, are threaded hole on the lower tire, under screw rod
End is screwed in the screwed hole, and the upper end of screw rod wears the centre bore of tire；The top of screw rod is fixed with suspension 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 more than bottom thickness, and ringfeder is then opposite；Punching is arranged at the annulus between ringfeder and positioning tube, is laminated vertically
Set；Insertion groove lining bar in the locating slot of punching, the upper end of the groove lining bar are set in the through hole of tire.
The conical surface and the angle of vertical direction are 3-5 degree.
The upper tire sets compression platform, and the compression platform is arranged at the annulus between ringfeder and positioning tube；Upper tire and hydraulic pressure
The pressure head of machine is corresponding.
The initial position of ringfeder is arranged on lower tire upper surface, and the initial position of internal expanding core is higher than ringfeder.
The utility model has the advantages that：As a result of outer press mounting and interior press fitting two ways, and internal expanding core, ringfeder offset
The face connect is the conical surface, so ensures that internal expanding core progressively radially elapses ringfeder, will not cause the same time shift of punching
When dynamic due to location conflicts and caused by punching deform；In addition, being also convenient for the dismounting of mold, lacking for straight barrel type internal expanding core is overcome
Fall into.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 top view.
Embodiment
The utility model is illustrated below in conjunction with the accompanying drawings, and as shown in Figure 1 and Figure 2, the utility model includes lower tire 1, described
Hole is threaded on lower tire, the lower end of screw rod 2 is screwed in the screwed hole, and the upper end of screw rod 2 wears the centre bore of tire 3；Screw rod
Top be fixed with suspension ring 4；Locking nut 5 is also set up above screw rod；Internal expanding core 6 is set gradually outside the screw rod, is risen
Set 7 and positioning tube 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 more than bottom
Thickness, and ringfeder be then on the contrary, can so ensure when upper tire pushes internal expanding core 6, ringfeder 7 is progressively radially outer to be moved, and is avoided excessive
When punching is simultaneously mobile due to location conflicts and caused by deformation；Punching 9 is arranged at the annulus between ringfeder 7 and positioning tube 8, edge
Axially stacked setting；Insertion groove lining bar 11 in the locating slot of punching, the upper end of the groove lining bar are set in the through hole of tire.
The conical surface 10 and the angle of vertical direction are 3-5 degree.
The upper tire sets compression platform 12, and the compression platform 12 is arranged at the annulus between ringfeder and positioning tube；Upper tire with
The pressure head of hydraulic press is corresponding.
The initial position of ringfeder is arranged on lower tire upper surface, and the initial position of internal expanding core is higher than ringfeder.
Claims (3)
- A kind of 1. permanent-magnet synchronous variable-frequency electric machine rotor dress pressure tire, it is characterised in that：Including lower tire, it is threaded on the lower tire Hole, screw rod lower end are screwed in the screwed hole, and the upper end of screw rod wears the centre bore of tire；The top of screw rod, which is fixed with, hangs 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 more than bottom thickness, and ringfeder is then opposite；Punching is arranged at the annulus between ringfeder and positioning tube, It is stacked vertically；Insertion groove lining bar in the locating slot of punching, the upper end of the groove lining bar are set in the through hole of tire.
