Description
Technical field
The utility model relates to the industrial sewing machine servomotor, specifically a kind of industrial sewing machine servo motor stator partitioned organization.
Background technology
The current servo electric system extensively adopts on industrial sewing machine, servo electrical machinery system is little with volume, moment is high, function is complete, noise is low, make the precision height, and the excellent functional characteristics such as decrease energy consumption, substitute just fast the clutch motor of traditional induction structure comprehensively, realize the high-quality of servomotor, High-efficient Production, at first institute's problem needing to overcome is the problem of motor stator winding automated production, and the conventional employed stator of machine automatic line inserting mostly is the stator of full circle shape trough of belt, stator is placed on the frock of coil inserting apparatus, by pawling winding coil is pushed in the stator slot, the stator that this rule mode is produced has three weakness: the one, because coil is to push by pawling that the arrangement of winding in groove can be too not neat in the groove, the space can not be fully utilized in the stator slot, therefore the stator copper factor can not be too high, and perfect condition also only reaches about 80%; The 2nd, stator winding is to embed, so two ends must stay the end of certain-length longer as the activity space both ends, has increased the loss of stator winding; The 3rd, because coil will enter in the groove by notch, stator punching must leave the notch of one fixed width, the opening size of stator slot, it is the important parameter of strict control in the design of electrical motor, the notch size is directly proportional with magnetic leakage, the required width of rebate of machine automatic line inserting is usually wide than the notch of hand insertion, can cause the increase of the magnetic leakage of motor winding, and electromagnetic conversion efficient will reduce.。
The utility model content
The purpose of this utility model is to adopt divided stator block structure and coiling, the stator press-loading complete set technology supporting with it effectively to solve stator machine automatic winding problem, the block stator technical pattern of this patent and machine automatic winding technology, technology mode implements easier, reliable than the machine automatic line inserting, for the service efficiency that improves stator and reduction raw materials consumption larger advantage is arranged.
For achieving the above object by the following technical solutions:
A kind of industrial sewing machine servo motor stator partitioned organization, it is characterized in that: stator is divided into the piece number that equates with the groove number, interface is just in the centre of stator slot, form the identical T shape piecemeal of polylith shape, plug insulating support at single T shape piecemeal, after T shape piecemeal coiling, again T shape piecemeal is combined into and is circle band winding stator.
Interface at two adjacent T shape piecemeals is provided with cooperatively interact locating convex block and detent.
A kind of industrial sewing machine press-loading apparatus of servo motor stator partitioned organization, it is characterized in that: it is provided with patrix, middle mould and counterdie from top to bottom successively, patrix top and connecting power device, patrix and middle mould can move up and down along guide pillar, center at middle mould offers through hole, it is suitable for reading slightly little than end opening that through hole is truncated cone-shaped, and through hole can be combined into circular band winding stator for T shape piecemeal and pass the through hole location notch that also is provided with casing suitable for reading; The position corresponding with middle mould through hole at described counterdie is provided with push-down head, and the push-down head top is provided with the screens that stator is placed, and also is provided with locating piece at described counterdie top.
Between patrix and power set, also be provided with upper bracket.
This patent have winding stator manufacture craft also different to some extent from conventional machine automatic line inserting, the interface of T shape piecemeal is in the middle of stator slot, T shape piecemeal is fully open in assembly unit front stator flute profile, coil is to be wound on the stator insulation support, winding process is finished automatically by machine, after block stator all winds the line and finishes, be spliced into again circular stator, the coil of this technique manufacturing has just in time been avoided three weakness of machine rule, the one, the machine Automated winding, winding marshalling copper factor is high, and copper factor can easily reach 90%, so just can bring into play to large extent the service efficiency of stator core; The 2nd, coil adopts coiling to be shaped, and the winding coil turn-to-turn is to be tension, so end winding is very little, only have common rule end winding 1/2～1/3 between, the end reduce not only to have saved raw material, and effectively improved the usefulness of winding, the internal resistance of winding is reduced, and efficient improves; The 3rd, because being the shape piece, stator forms, after complete, be combined into again circular stator, because coil winding is finished, do not needed notch, so the slit design of notch is very little, almost close to zero, so the loss of magnetic leakage is very little, so just greatly improved the efficient that the winding stator is arranged.
The stator winding that three comprehensive above advantages adopt the art of this patent to produce can be saved material and dwindle motor volume, and in the Same Efficieney situation, it is about 25% that core length can shorten, and reduces copper material and consume 50%.Under current and Future condition day by day in short supply, the technique improvement has great significance, and will play demonstration effect to from now on material-saving, high efficiency motor manufacturing.
