Abstract
The invention relates to a manufacturing method of a partitioned stator of a servo motor of an industrial sewing machine. The manufacturing method comprises the following steps of: dividing a stator into blocks with the number equal to that of grooves, wherein interfaces are positioned in the centers of stator grooves; and forming a plurality of T-shaped sub-blocks, inserting an insulating bracket in the single T-shaped sub-block, splicing the T-shaped sub-blocks into a circular stator with a winding after the T-shaped sub-blocks are coiled, and pressing the circular stator with the winding into a housing case by a press fitting apparatus provided by the invention. According to the manufacturing method and the special press fitting apparatus of the partitioned stator of the servo motor of the sewing machine, a partitioned stator technique and an automatic machine coiling technique are matched; and compared with a automatic machine inserting winding manner, the process manner is simpler, more convenient and more reliable to be implemented and has greater superiorities on improving the use efficiency of the stator and reducing the consumption of raw materials.
Description
Technical field
The present invention relates to industrial sewing machine servomotor, specifically a kind of industrial sewing machine servo motor stator piecemeal
Structure.
Background technology
Current servo electric system is widely used on industrial sewing machine, servo electrical machinery system with small volume, torque it is high,
Function is complete, noise is low, sewing high precision, and the excellent functional characteristic such as energy consumption is greatly lowered, just quick to substitute heritage comprehensively
The clutch motor of structure is answered, high-quality, the efficient production of servomotor is realized, the problem that must be solved first is motor stator
The problem of winding automation production, and the stator used by the machine automatic line inserting of routine is mostly the stator of full-circle spray pattern trough of belt,
Stator is placed in the frock of coil inserting apparatus, winding coil is pushed in stator slot by pawling, the stator of this wire embeding ways production
There are three weakness：One be due to coil be arrangement of the winding in groove is pushed in groove by pawling will not be too neat, in stator slot
Space can not be fully utilized, therefore stator copper factor can not possibly be too high, and perfect condition is also only up to 80% or so；Two be stator around
Group is embedded, and two ends must stay the end of certain length as activity space so both ends are longer, increased stator winding
Loss；Three will be entered in groove by notch due to coil, and stator punching must leave the notch of one fixed width, the opening of stator slot
Size, is the important parameter of strict control in design of electrical motor, and notch size is directly proportional to magnetic leakage, the groove needed for machine automatic line inserting
Mouth width is generally wide than the notch of hand insertion, can cause the increase of the magnetic leakage of machine winding, and electromagnetic conversion efficiency will
Reduce..
The content of the invention
It is an object of the invention to adopt stator partitioned organization and the coiling supporting with which, stator press-loading complete set technology effective
Solve the problems, such as stator machine automatic winding, the block stator technical pattern and machine automatic winding technology of the patent, technique
Mode implements easier, reliability compared with machine automatic line inserting, for the service efficiency and reduction raw materials consumption that improve stator
There is bigger advantage.
Employ the following technical solutions for achieving the above object：
A kind of manufacture method of industrial sewing machine with servomotor block stator, it is characterised in that：（1）Design piecemeal fixed
The technical pattern of son, produces the block stator piece of the technical pattern with the mode of wire cutting, is combined into certain stator for folding thickness
Lamination, makes punching, lamination mould, and produces T-shaped piecemeal；（2）The stator insulation support for meeting the stator lasmination is redesigned out,
Insulating support injection mould is made, insulating support is produced；（3）Insulating support is plugged on T-shaped piecemeal, and passes through automatic winding
Machine completes coiling；（4）The wound stator piecemeal for completing is combined into into circular wound stator, by iron wire banding；（5）By iron wire
The circular wound stator of banding is mounted on the push-down head of press-loading apparatus, while casing is arranged on the locating slot of middle mold, is opened
Press-loading apparatus, push-down head coordinate compression casing with middle mold, and move downward casing, as the through hole of middle mold center is in round platform
Shape, the mouth compared with suitable for reading of truncated cone-shaped through hole are slightly smaller, and when circular wound stator passes through the through hole, stator outer diameter tightens up into the outer of setting
Footpath size, then circular wound stator is pressed in casing by push-down head, complete to make.
This patent have wound stator processing technology with routine machine automatic line inserting it is also different, T-shaped piecemeal
Separating surface is that, in the middle of stator slot, T-shaped piecemeal is in completely open in assembled front stator flute profile, and coil is to be wound on stator insulation
On support, winding process is automatically performed by machine, after the completion of block stator whole coiling, then is spliced into circular stator, the technique
The coil of manufacture just avoids three weakness of machine rule, and one is Machine automated coiling, the neat copper factor of coils arrangement
Height, copper factor can be easily reached 90%, thus can play the service efficiency of stator core to large extent；Two is that coil is adopted
Shaped with coiling, winding coil turn-to-turn is therefore the end turn very little in tension, only usual the 1/ of rule end turn
Between 2～1/3, raw material has not only been saved in the reduction of end, and is effectively improved the efficiency of winding, makes the internal resistance of winding
Reduce, efficiency is improved；Three be shape piece composition due to stator, be combined into circular stator again after complete, due to coil winding
Complete, do not needed notch, so the slit design of notch is very little, nearly close to zero, so the loss very little of magnetic leakage, this
Sample has been considerably improved the efficiency of wound stator.
Three advantages more than comprehensively can material-saving and diminution motor body using the stator winding of the art of this patent production
Product, in the case of Same Efficieney, core length can shorten about 25%, reduce copper material and consume 50%.Now with Future increasingly
Under conditions of in short supply, technique is improved and is had great significance, and will play demonstration effect to saving material, high efficiency motor manufacture from now on
Should.
