Description
Technical field
The present invention relates to phase insulation design field, particularly a kind of interphase insulating sheet of automatic embedding.
Background technology
The stator of AC asynchronous motor consists of jointly stator core, stator winding, and stator winding is formed through coil winding machine coiling by enamelled wire, then by coil inserting apparatus, winding is embedded in stator core.Stator winding comprises main winding and auxiliary winding, because winding is to be formed by coil winding machine coiling, by operating personnel, be placed on coil inserting apparatus again, may cause the magnet wire insulation layer of main winding and auxiliary winding impaired, for preventing that main winding and auxiliary winding is by short circuit, insulating trip need to be set between main winding and auxiliary winding conventionally and separate, this insulating trip is interphase insulating sheet.
Conventional interphase insulating sheet is strip at present, as shown in Figure 1, after winding being embedded in stator core by coil inserting apparatus, enter next process, operating personnel use hand and instrument that main winding and auxiliary winding is opened for 1,2 minutes, then the interphase insulating sheet of strip 3 is put into, completed the placement of interphase insulating sheet.There is many deficiencies in operation like this: (1) can not separate main winding and auxiliary winding completely; (2) when use instrument separates main winding and auxiliary winding, easily cause enamelled wire impaired, produce fault; (3) independent post need to be set and special operating personnel carry out this work; (4) quality can not be guaranteed.
Summary of the invention
The object of the present invention is to provide a kind of interphase insulating sheet of automatic embedding, in wire insertion technology, directly complete the setting of interphase insulating sheet, convenient and swift, reliable in quality.
For realizing above object, the technical solution used in the present invention is: a kind of interphase insulating sheet of automatic embedding, the body of insulating trip is the sheet of annular, the annulus inner side of insulating trip is along circumferentially offering tooth or channel-shaped portion, the even interval of described tooth or channel-shaped portion layout, the quantity of tooth or channel-shaped portion is consistent with stator progression.
Compared with prior art, there is following technique effect in the present invention: interphase insulating sheet is arranged to this shape, then directly by coil inserting apparatus, complete the setting of interphase insulating sheet, the inconvenience of having avoided manual operation to bring, saved manual operation operation in the past simultaneously, greatly reduce cost, and saved the spent time of this operation.

Embodiment
Below in conjunction with Fig. 1 to Fig. 5, the present invention is described in further detail.
For the understanding of the present invention of being more convenient for, first the rule process of coil inserting apparatus is underdrawed here.First good main winding 1, auxiliary winding 2, the stator core of coiling is put on coil inserting apparatus successively, under the effect of coil inserting apparatus push rod, main winding and auxiliary winding 1,2 embedded in stator core automatically.When main winding and auxiliary winding 1,2 is placed on coil inserting apparatus, main and auxiliary winding 1,2 planes at place and the axis direction of stator core are vertical; After main winding and auxiliary winding 1,2 is embedded in stator core, main winding and auxiliary winding 1,2 planes at place and the axis direction of stator core are parallel.In prior art, after wire insertion technology completes, operating personnel are placed on the interphase insulating sheet of strip between main winding and auxiliary winding 1,2, and now, the state that the insulating trip of strip presents is round belt shape as shown in Figure 2.
Consult Fig. 3, Fig. 5, an interphase insulating sheet for automatic embedding, the body of insulating trip 10 is the sheet of annular, and the annulus inner side of insulating trip 10 is along circumferentially offering tooth or channel-shaped portion, the even interval of described tooth or channel-shaped portion layout, the quantity of tooth or channel-shaped portion is consistent with stator progression.Because the body of insulating trip 10 is sheet, so the tooth here or channel-shaped portion refer to: the annulus inner side of insulating trip 10 inwardly cuts out the profile shape that forms tooth between a profile that forms channel-shaped portion or adjacent channel-shaped portion.
When insulating trip 10 is placed on coil inserting apparatus, consistent with the state that main winding and auxiliary winding 1,2 is placed on coil inserting apparatus, the face at insulating trip 10 places is also vertical with the axis direction of stator core.Insulating trip 10 was clamped between main winding and auxiliary winding 1,2 before rule.Along with the work of coil inserting apparatus, insulating trip 10 is along with main winding and auxiliary winding 1,2 is moved and is embedded in stator core together, and insulating trip 10 starts to end from rule, is in all the time between main winding and auxiliary winding 1,2, plays the effect of phase insulation.Insulating trip 10 starts to end at rule, and change has occurred the state that its body presents.Insulating trip 10 is its grown form when unassembled, is annular shim-like, as shown in Fig. 3,5; The state that insulating trip 10 in embodiment mono-has presented while having pushed assembling by automatic coil inserting apparatus is that one end is that train of dress shape, one end are the cylindrical shape of tooth and gap shape, as shown in Figure 4.When grown form, the outer shroud girth of insulating trip 10 is greater than the girth of interior ring, when it becomes stereoscopic-state, can not present round belt shape as shown in Figure 2, the interior ring of insulating trip 10 can be subject to tension force and produce and to break, and through inventor's unremitting effort, inventor finds as long as some teeth are set on interior ring or channel-shaped portion just can have been avoided the appearance of this situation, the quantity of tooth or channel-shaped portion must be consistent with stator progression, and what each tooth or channel-shaped portion were corresponding is a place that tension force is larger.
Tooth or channel-shaped portion set-up mode are various, inventor's discovery after test various structures, and the set-up mode of embodiment mono-, two has more effectively reduced the generation of insulating trip 10 damaged phenomenons.
Embodiment mono-:
As preferred version of the present invention, edge, the annulus of described insulating trip 10 inner side circumferentially offers channel-shaped portion 11, two cell wall portions, 111,112 layouts parallel to each other of described channel-shaped portion 11, and the straight line at two cell wall portion 111,112 places is symmetrical about described circle ring center; Described trench bottom 113 is circular-arc, and the center of this circular arc is consistent with the center of described annulus.It is excessive that channel-shaped portion 11 is offered, and is unfavorable for the insulation between main winding and auxiliary winding 1,2; That offers is too small, there will be the fracture phenomena of insulating trip 10.Here, preferably, the width of insulating trip body 10 and the width of auxiliary winding between adjacent two grooves 11 match.
Embodiment bis-:
As preferred version of the present invention, the annulus inner side of described insulating trip 10 is corrugated, and away from the described grooved portion 11 of trough formation of circle ring center, the size of ripple is also worthy of careful study, to offer large and small principle the same with the channel-shaped portion 11 in embodiment mono-, is just no longer described in detail here.
When being placed on coil inserting apparatus, insulating trip 10 to note to some extent, when described insulating trip is placed between main winding 1 and auxiliary winding 2, channel-shaped portion 11 center line is radially corresponding with main winding 1 one of them coil center line radially, if the top coil of main winding in Fig. 11 centerline direction is radially exactly the length direction that is the page, Fig. 1 and Fig. 3 institute position are correspondence position.Like this, channel-shaped portion 11 just can play its due effect.
