As shown in Figure 14 and Figure 15, holding device 40 in present embodiment comprises supporting bracket 41, one end of at least two locating pieces 42 is connected on the axial end of supporting bracket 41, and the other end of these locating pieces extends along the axis of supporting bracket, and these locating pieces have spacing 43 each other.And sheath 46, this sheath 46 is looped around supporting bracket 41 around, the internal face of sheath 46 is at least provided with two positioning bars 47, and these positioning bars 47 are distributed on the internal face of sheath, and the two ends of positioning bar 47 extend along the axis of sheath; And lowering or hoisting gear 60, one end of lowering or hoisting gear 60 is fixedly connected with supporting bracket or cylinder component, and the other end of lowering or hoisting gear 60 is connected with workbench.The internal face of described sheath 46 is at least provided with two groove 46a, these grooves 46a along the axial arranged of sheath and at least one end extends to the axial end of sheath, a part for described positioning bar 47 is embedded in groove, and the height of positioning bar 47 is less than the height of groove.Present embodiment is for the assembled stator lobe 10 of all needs, mounting means before splicing press-fits is divided into two-layer up and down putting, lower floor's stator lobe and upper strata stator lobe are put in the mode misplaced, and lower floor's stator lobe is placed in above lower floor's stator lobe, the cross-over connection junction surface 14 of the stator lobe 10 in lower floor's stator lobe, begin to take shape with the groove 13 of the stator lobe 10 in lower floor stator lobe and coordinate, the groove of the stator lobe 10 in the stator lobe of upper strata, begin to take shape with the cross-over connection junction surface 14 of the stator lobe 10 in lower floor stator lobe and coordinate, thus, lower floor's stator lobe forms supporting role to upper strata stator lobe.Although the winding section of each stator lobe 10 on upper strata can be supported preferably unlike the 1st execution mode, but in the clearance space of fan-shaped body 11 matched in clearance of stator lobe 10 between sheath 46 and locating piece 42, being equivalent to fan-shaped body 11 has been maintained in this space, weight due to fan-shaped body 11 is greater than the weight of winding section 12, therefore, the position of fan-shaped body 11 obtains good maintenance, each stator lobe 10 in upper strata to press-fit in process equally can held stationary descending.It should be noted that, for the 2nd execution mode, except holding device and the 1st execution mode are distinguished to some extent, the internal face of the gland body 54 in addition in press fitting device 50 does not need to arrange projection 55 again, and is directly put on press-fiting active force on the fan-shaped body 11 of stator lobe 10 by gland body 54.
Holding device also comprises the backing plate 48 between sheath and the upper surface of workbench, and backing plate 48 is provided with central through hole and is centered around the pilot hole around this central through hole; And guide rod 49 is on the supporting plate installed in one end, after the other end of guide rod 49 axially extends along supporting bracket, to extend in the pilot hole on backing plate 48 and to form matched in clearance with this pilot hole.The piston rod 61a of oil cylinder 61, through after through hole on table surface, is being connected with supporting bracket 41 through the central through hole on backing plate 48.When oil cylinder 61 is elevated with supporting bracket 41, under the effect of guide rod 49, make the elevating movement of supporting bracket 41 more steady.
The present invention is not limited to above-mentioned execution mode, such as, in the above-described first embodiment, cylinder component 44 also directly can adopt non-hollow cylinder, the periphery of this cylinder component 44 extends a radial flange, an axial end of this radial flange and the axial end of cylinder component in the same plane, supporting bracket is arranged a counterbore, radial flange is embedded in counterbore, by screw, radial flange and supporting bracket are carried out fastening again, thus cylinder component 44 and supporting bracket 41 are fixed as one.
In the 1st above-mentioned execution mode and the 2nd execution mode, the connected mode between locating piece 42 with supporting bracket 41 also can adopt the mode of directly welding to be fixed.In addition, lowering or hoisting gear 60 also can be the combination of cylinder and support.Lowering or hoisting gear 60 can also adopt spring 63 and guide post 64 to form (as shown in figure 16), spring 63 is enclosed within guide post 64, one end of spring 63 is fixedly connected with the bottom surface of supporting bracket 41 or cylinder component 44, the other end of spring 63 is fixed on the table top of workbench 30, guide post 64 is provided with the shaft shoulder, make one of guide post 64 section of diameter large, the diameter of another section of guide post 64 is little, the table top of workbench 30 is provided with shoulder hole, the end of the enlarged diameter section of guide post 64 is fixedly connected with the bottom surface of supporting bracket 41 or cylinder component 44, in the large directly reduced diameter section matched in clearance shoulder hole on the table of guide post 64.When supporting bracket 41 and cylinder component 44 are subject to the pressure effect of press fitting device 50, supporting bracket 41 or cylinder component 44 are to bottom offset, supporting bracket 41 or cylinder component 44 with guide post 64 to bottom offset, simultaneously, supporting bracket 41 or cylinder component 44 pairs of springs 63 apply pressure effect, spring 63 is compressed, when the step surface of the shaft shoulder on guide post 64 in shoulder hole in conjunction with time, supporting bracket 41, cylinder component 44 and guide post no longer decline, press-fit active force to continue to be applied on stator lobe 10, thus upper and lower two-layer stator lobe 10 is stitched together.After the pressure of press fitting device 50 is withdrawn, under the active force of spring 63, supporting bracket 41 and cylinder component 44 reset.In addition, for the linear actuator 53 in press fitting device 50, cylinder also can be selected to replace oil cylinder.Linear actuator 53 can also be made up of motor, reductor and screw body, to replace described oil cylinder.
Above-mentioned embodiment is only used to the present invention is described, and is not used as limitation of the invention, as long as in the spirit of the claims in the present invention, all will drop in the scope of the claims in the present invention the change of above-described embodiment, modification.
