As stated, particularly under the situation of the coil of all length, if adopt prior art, then along with the carrying out that inserts, with the radially inwardly traction of coil to iron core, because the interference of end winding 31 and slot wedge guide 11, coil 3 can sustain damage.If adopt this form of implementation; Then insert in the way of operation at coil; After the distance of leading section regulation of slot wedge guide 11 is left in the coil insertion end that makes unshakable in one's determination 1 is inserted the zero hour with respect to coil configuration; Begin coil 3 and the insertion of slot wedge 9 once more to groove 2, so, the interference of end winding 31 and slot wedge guide 11 reduced.According to this method, in step 5, because when the slot cell 2 of slot wedge 9 in core slots inserts, also can be without slot wedge push rod 10, so, there is no need slot wedge push rod 10 is transported to the position that the insertion of slot wedge 9 finishes.Therefore, when obtaining to reduce the effects of jamming of slot wedge guide 11 and end winding 31, slot wedge push rod 10 can not disturb with end winding 31, from this point, can reduce the damage of coil 3 yet.
In addition, in above-mentioned steps 3, put down in writing " through an end of slot wedge push rod 10 pushing slot wedges 9; slot wedge 9 is inserted in the slot cell unshakable in one's determination 2 "; But, in whole orders of step 3, be not to insert slot wedge 9 through the pushing of slot wedge push rod 10.If from the beginning or from just can slot wedge 9 be inserted in the slot cell 2 without slot wedge push rod 10 midway, utilize this method, for example with the method identical with step 5 can situation with slot wedge 9 insertions under, also can utilize this method insertion.In this case, in coil inserting device, also can not assemble slot wedge push rod 10 sometimes.
In addition; In keeping out of the way in the order of step 4, the support driving mechanism unshakable in one's determination that drives support unshakable in one's determination along unshakable in one's determination 1 axial direction is set, whereby; Change unshakable in one's determination 1 bearing position; Make unshakable in one's determination 1 with respect to the position of in first operation, setting unshakable in one's determination 1 coil insertion end along the distance of keeping out of the way regulation away from the direction of the leading section of slot wedge guide 11, still, also can replace to be provided with and make slot wedge guide 11 along by the slot wedge guide driving mechanism of the axial direction of the iron core 1 of support part supports unshakable in one's determination action; Through driving slot wedge guide 11, make the distance of leaving regulation between the leading section of unshakable in one's determination 1 coil insertion end and slot wedge guide 11.In this case, also can omit support driving mechanism unshakable in one's determination, still, also can stay the adjustment that is provided with that is used for iron core.
Also can the keep out of the way mechanism of two mechanisms as the distance between the leading section of the core side that changes aforementioned iron core and aforementioned slot wedge guide be positioned.
Form of implementation 2
This form of implementation is for about " side of separator 4 with the frictional force of the face of the slot wedge 9 of subtend " with it described in the step 5 that strengthens form of implementation 1, so that reliably slot wedge 9 is described to the concrete grammar of core slots insulation spacer 2 insertions and the invention of coil inserting device.
Fig. 3 (a) is the cutaway view of the separator 4 in the expression form of implementation 2 of the present invention (b).Profile direction is identical with Fig. 1.Fig. 3 (a) (b) in, 41 the expression separators 4 leading section, 42 the expression separators 4 the side; 43 expressions are built in the friction member in the separator 4; Here, as concrete example, express jagged projection is processed the situation towards the shape of the radial outside of separator.The 44th, friction member 43 is received into the accommodating chamber of the inside of separator 4.For this friction member 43,, can or utilize of the direction expansion of the structure of spring by the drive unit that utilizes cylinder etc. to separator side 42 though do not show in the figure.
Before coil inserts; Shown in Fig. 3 (a), friction member 43 is received in the accommodating chamber 44, as making friction member 43 produce the frictional resistance portion of the part of frictional force; For example, in Fig. 3, be formed with jagged part and be in the state that does not expose from the side 42 of separator 4.In this state, the order of the step 1 of carrying out form of implementation 1 to 3.The order of step 4 is implemented after the coil 3 of ormal weight and slot wedge 9 are inserted in the slot cell 2 unshakable in one's determination.In step 5; Shown in Fig. 3 (b), frictional resistance portion exposes from the side 42 of separator 4, the slot wedge 9 of nipping; Increase side 42 and the frictional force between the face of the slot wedge 9 of subtend with it; In this state, through separator 4 is inserted iron core 1, the slot cell 2 of slot wedge 9 to iron core inserted.According to this method; Owing to make friction member 43 expansions, making frictional resistance portion after separator side 42 is exposed; Also can be when slot cell 2 inserts at slot wedge 9 without slot wedge push rod 10, so, there is no need slot wedge push rod 10 is passed out to the insertion end position of slot wedge 9.Thereby when obtaining to reduce the effects of jamming of slot wedge guide 11 and end winding 31, slot wedge push rod 10 does not disturb with end winding 31 yet, can reduce the damage of coil 3.In addition, after the insertion of slot wedge 9 finishes,, slot wedge 9 still is inserted in the groove 2, only separator 4 is extracted from unshakable in one's determination 1 once more through friction member 43 is received in the accommodating chamber 44 of separator 4.
Fig. 4 (a) (b) representes to be contained in friction member 43 example of 42 mechanisms of exposing from the side in the accommodating chamber 44 of separator 4.Here, the leading section 41 of separator 4 jut 411 that stretches out of the below of heart portion tool directed graph therein.And this jut 411 has from its surface towards the groove 412 of oblique below, and the jut 431 of friction member 43 is fitted in this groove 412.And then, leading section 41 by the elastomer that is arranged on its both ends bear portion 413, the elastomer on top that is set at the accommodating chamber 44 of separator 4 via elastomer 45 bears portion's 443 supportings.Friction member 43 can be supported along the left and right directions of figure by the upper interior 441 of its accommodating chamber 44 and lower interior 442 movably.On the leading section 41 of separator 4, do not apply under the state of load; Elastic restoring force by the elastomer 45 that is installed in above-mentioned accommodating chamber 44 tops; The leading section 41 of separator 4 is lifted; Jut 411 through leading section 41 moves to identical direction, and friction member 43 becomes the state in the accommodating chamber 44 that is received into separator 4.
Fig. 4 (b) expression applies the state when loading from the leading section 41 of the last direction separator 4 of figure.Elastomer 45 deflections corresponding to load, leading section 41 sinks to the below of figure.At this moment, jut 411 also sinks to identical direction, so, the power of utilizing the jut 431 that is fitted to the friction member 43 on the groove 412 that is arranged on the jut 411 to receive, friction member 43 is to the left and right directions expansion of figure.And when the spring rate according to elastomer 45, the load of regulation continues to be applied to 41 last times of leading section, and the frictional resistance portion of friction member 43 keeps being exposed to the state in the outside of side 42.On the other hand, if above-mentioned load reduces or disappears, by the restoring force of elastomer 45, friction member 43 is received in the accommodating chamber 44 once more.
Through separator 4 being inserted in unshakable in one's determination 1, produce the load that forward end 41 applies.That is, the bundle of the coil 3 of coiling is divided and is carried on the leading section 41 of separator 4 by blade 5, in that separator 4 was inserted 1 o'clock unshakable in one's determination, simultaneously coil 3 is inserted in the core slots.Resistance when this coil inserts becomes reaction force, becomes the load that forward end 41 applies.Thereby along with the carrying out of the insertion of coil 3, this load becomes big, and the frictional resistance portion of friction member 43 is exposed to outside the side 42 of separator 4.Otherwise when separator 4 was extracted from unshakable in one's determination 1, the load that forward end 41 applies disappeared, and friction member 43 is received in the accommodating chamber 44 of separator 4.Like this, owing to the frictional force between the side 42 of slot wedge 9 and separator 4 reduces significantly, so, be retained under the state constant in the core slots at slot wedge 9, can separator 4 be extracted from unshakable in one's determination 1.
Fig. 5 (a) (b) representes to be contained in the another one example that separator 4 interior friction members 43 are exposed to the mechanism outside the side 42.Here; Friction member 43 via the upper interior 441 and the lower interior 442 of the accommodating chamber 44 of separator 4, be positioned at leading section 41 central portions jut 411 the side and be configured in the elastomer 46 on the upper side 444 of inside of accommodating chamber 44, can be bearing in movably in the accommodating chamber 44 along left and right directions.And then the following part of friction member 43 has the rake 433 that tilts towards the top to the side of jut 411 from it midway, is also supported with lobe plate 47 that any one rake 433 of the friction member 43 of the left and right sides that is configured in figure all contact.Through make 49 actions of lobe plate driving mechanism via its driving shaft 48, drive this lobe plate 47 along the above-below direction among the figure.At ordinary times, shown in figure (a), friction member 43 is in the state in the accommodating chamber 44 that is accommodated in separator 4.Secondly, shown in Fig. 5 (b), under the situation that makes 49 actions of lobe plate driving mechanism, driving shaft 48 is driven above scheming, lobe plate 47 also moves to the top, through moving of this lobe plate 47, on the rake 433 of friction member 43, applies power.By this power; Friction member 43 resistances are with the elastic-restoring force of the elastomer 46 of elastomer bearing plane 432 contacts; To the left and right directions expansion of figure, when lobe plate 47 rise regulation apart from the time, the frictional resistance portion that becomes friction member 43 reaches the state outside the side 42 of separator 4.Under the situation that driving shaft 48 is driven below scheming, lobe plate 47 also moves downwards, and friction member 43 is received in the accommodating chamber 44 of separator 4 by the elastic-restoring force of elastomer 46.By this mechanism, because the control through lobe plate driving mechanism 49, direction of action that can arbitrary decision driving shaft 48, so, have the advantage that also can carry out arbitrarily with the control of the frictional force of slot wedge 9.
In form of implementation 1, the moment of keeping out of the way order in step 4, the coil 3 and the slot wedge 9 of ormal weight is inserted in the core slots, its reason is for can be along the insertion of carrying out thereafter (in the step 5) coil 3 and slot wedge 4 slidingly.Here, for this point, slightly at length describe.
At first, describe for the situation of using the mechanism of Fig. 4 (a) shown in (b).On leading section 41 at separator 4, be accompanied by the load that causes by coil 3 and reach setting when above to the insertion of core slots insulation spacer 2, friction member 43 reaches outside the side 42 of separator 4.When becoming this state owing to do not utilize slot wedge push rod 10 just can slot wedge 9 be inserted in the slot cell 2 in the core slots, so, after becoming the moment of this state, at any time can implementation step 4 keep out of the way in proper order.But; When carrying out the transition to step 4 under the state that does not reach the amount to a certain degree of in slot cell 2, inserting at coil 3 and slot wedge 9 as yet; With under the configuration relation unsure state of coil 3 and slot wedge 9, carry out the transition to step 5 and be associated, exist and insert unusual danger, so be unfavorable.In addition, when tiding over to the mistake of step 4 when slow, the insertion sequence of step 3 is carried out under the state that the length of end winding 31 shortens, and exists the problem that end winding 31 and slot wedge guide 11 disturb.Thereby; Consider from angle to the insertion of core slots insulation spacer 2; Coil 3 and slot wedge 9 are inserted into the stable degree of the configuration relation of coil 3 and slot wedge 9 in slot cell 2 after; And do not use slot wedge push rod 10, by the side 42 (correctly saying the frictional resistance face of friction member 43) of separator 4 and the frictional force of slot wedge 9; Become can together slot wedge 9 be inserted into the moment of the state in the slot cell 2 with coil 3 after, preferably in the order of keeping out of the way of as far as possible early moment steps performed 4.Through making an experiment in advance, can grasp the timing of satisfying this condition.
Secondly, describe for the situation of using the mechanism of Fig. 5 (a) shown in (b).In this case, can be through making lobe plate driving mechanism 49 action, set arbitrarily friction member 43 is stretched out the timing outside the side 42 of separator 4.Thereby; Consider from angle to the insertion of slot cell 2; After coil 3 and slot wedge 9 are inserted into slot cell 2 in the degree stable to the configuration relation of coil 3 and slot wedge 9,, just can at any time slot wedge 9 be inserted in the slot cell 2 without slot wedge push rod 10.With top said the same,, preferably, after satisfying above-mentioned condition, carry out the transition to step 4 apace in order to reduce the interference of end winding 31 and slot wedge guide 11.For the timing of satisfying this condition, as top described, can grasp through pretest.In addition, use the insertion of the slot wedge 9 of this mechanism, also can implement, in this case, do not need slot wedge push rod 10 from the stage of step 3.
