Locating core 11 adopts the mode of matched in clearance to be vertically positioned in stator punching 9 endoporus, and locating core 11 seam is upward。
To the distance of the wedge shape inclined hole gauge sum less than cope match-plate pattern 6, lobe combined pressure plate 8 and base plate 12 bottom guide pillar 7, to guarantee that wedge 5 can produce pretensioning effect after inserting；The wedge shape inclined hole on guide pillar 7 top all exposes when stator punching 9 is compacted。
The angle of the angle of inclination of wedge 5 and wedge shape inclined hole upper edge is consistent。
Lobe combined pressure plate 8 laminate the thickness thickness less than stator punching 9, therefore in the lamination process of stator punching 9, it is possible to play position-limiting action, it is prevented that inner-stator iron core excessively produces butterfly-shaped deformation because compressing。
Preferably, trim ring 3 and bracket sleeve tube 4 have the wide arc gap of 0.1mm, are placed on repressurization on bracket sleeve tube 4。
The guide pillar 7 of the present embodiment frock both sides is one to one with the hole of lobe combined pressure plate 8 and cope match-plate pattern 6, it is impossible to exchange。
Lobe combined pressure plate 8 is using the perpendicular bisector between two auxiliary positioning holes as demarcation line, after extracting two groove lining bars 10, adopts the mode of line cutting to be divided into two by lobe combined pressure plate 8, then radially deviates from。
A kind of box-like inner-stator iron core stack-press assembly method of lobe, comprises the following steps:
S1: locating core 11, stator punching 9, groove lining bar 10, base plate 12, guide pillar 7, backing plate 13, lobe combined pressure plate 8, cope match-plate pattern 6 are provided；
S2: first insert locating core 11 in resonable 48 good stator punchings 9, then press symmetry direction two groove lining bars 10 of insertion；Using it as entirety, it is placed on base plate 12, and makes two groove lining bars 10 insert respectively in base plate 12 respective aperture；Guide pillar 7 and the upper end of described groove lining bar 10 it is inserted in respectively after being closed up by lobe combined pressure plate 8；Lobe combined pressure plate 8 covers cope match-plate pattern 6 again along two guide pillars；
S3: compression leg 2, pressing plate 1 are provided；
S4: place the pressing plate 1 with compression leg 2 at cope match-plate pattern, pressurize with aerostatic press, now lobe combined pressure plate 8 and base plate 12 have gap, and the wedge shape inclined hole part on guide pillar 7 top falls in cope match-plate pattern 6 hole；
S5: pressing plate 1, compression leg 2, wedge 5 are provided；
S6: lobe combined pressure plate 8 is pressed on base plate 12, the wedge shape inclined hole on guide pillar 2 top exposes outside cope match-plate pattern 6, and wedge 5 inserts wedge shape inclined hole；Operation aerostatic press backhaul, and take off the pressing plate 1 with compression leg 2, wedge 5 is reversed compression；
S7: bracket sleeve tube 4, trim ring 3 are provided；
S8: overlap trim ring 3 on bracket sleeve tube 4, overlaps bracket sleeve tube 4 on locating core 11 seam and pressurizes, so as to close-fitting press-in stator punching 9 endoporus, locating core synchronizes to exit；
S9: pressing plate 1, compression leg 2 are provided；
S10: by the pressing plate 1 combined and compression leg 2, compresses cope match-plate pattern 6 again, will obtain the wedge 5 loosened and extracts；Each part is taken off from top to bottom successively after removing pressure, now lobe combined pressure plate 8, stator punching 9, groove lining bar 10 and bracket sleeve tube 4 are still integrated, first extracted out by groove lining bar 10, then the lobe combined pressure plate 8 being divided into two by line cutting can be extracted out from the radial direction of bracket sleeve tube 4 with stator punching 9 easily。
In sum, this utility model has reached that the regularity of stator punching requires, internal-external circle concentricity requires and repeatedly discrete piece positioning requirements in a mold before dress, and simple in construction, easy to operate, reliable product quality。
Below in conjunction with Fig. 1 to Figure 15 and embodiment, the utility model is described in further detail。
The location of this frock:
This frock (Fig. 3) is different from traditional location mode, and it is with stator inner hole for main location, and with two circular trough lining bars for auxiliary positioning, this is determined by the special construction of this stator。Stressing, locating core 11 (Fig. 4) adopts matched in clearance with stator punching 9 endoporus, and while bracket sleeve tube 4 is pressed into, locating core 11 is synchronized to exit。
This frock press-fit parsing:
Before entering bracket sleeve tube 4, stator punching 9 necessarily be in compacted state。The pre-compression component that pressing plate 1 (Fig. 5) and compression leg 2 (Fig. 6) form first compresses cope match-plate pattern 6 (Fig. 7,8) pressure transmission is passed through, cope match-plate pattern 6 compresses lobe combined pressure plate 8 (Figure 11,12), lobe combined pressure plate 8 compresses stator punching 9, and stator punching is compacted, when keeping this pressure, two pieces of wedges 5 (Fig. 9,10) are rapidly inserted in the wedge shape inclined hole of guide pillar 7 (Figure 13)。Now removing pressing plate 1 and the pre-compression component of compression leg 2 composition, by the little gradient auto-lock function of wedge 5, stator punching 9 is still in impaction state, and bracket sleeve tube 4, under the guiding of locating core 11 seam, also can easily be pressed into。
The operation principle of this frock:
As in figure 2 it is shown, first resonable 48 good stator punchings insert locating core 11, then press symmetry direction two groove lining bars 10 of insertion；Using it as entirety, it is placed on the base plate 12 of Fig. 2 mould, and makes two groove lining bars 10 insert respectively in the respective aperture of base plate 12；Guide pillar 7 and the upper end of groove lining bar 10 it is inserted in respectively after being closed up by two lobe lobe combined pressure plates 8；In order to ensure to press under equilibrium, lobe combined pressure plate 8 covers cope match-plate pattern 6 again along two guide pillars 7；In order to reach the purpose of pre-pressing, place the pressing plate 1 (Fig. 5) with compression leg 2 (Fig. 6) at cope match-plate pattern 6, and pressurizeed；While stator punching 9 is compacted, the wedge shape inclined hole on guide pillar 7 top all exposes, and now just can be inserted by wedge 5；Operation aerostatic press backhaul, to release top pretightning force, and takes off the pressing plate 1 (Fig. 5) with compression leg 2 (Fig. 6), and due to the elastic return of stator punching, wedge 5 is reversed compression；Locating core 11 seam overlaps bracket sleeve tube 4 and pressurizes, so as to close-fitting is pressed in the endoporus of 48 stator punching 9 compositions。
Work immediately after is demoulding pickup, each part is taken off by order from top to bottom, now Figure 11, lobe combined pressure plate 8 in 12, stator punching 9 and groove lining bar 10 are still integrated, but only need to first be extracted out by groove lining bar 10, then the lobe combined pressure plate 8 being divided into two by line cutting can be extracted out from the radial direction of bracket sleeve tube 4 with inner-stator iron core (Fig. 1) easily。
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should be encompassed within protection domain of the present utility model。Therefore, protection domain of the present utility model should be as the criterion with scope of the claims。
