A kind ofly be suitable for producing electric motor internal stator iron core in order to explore, and moulding is reliable, the operation of band material is smooth and easy, the coiler device unshakable in one's determination of high efficiency, the scientific research personnel has designed a kind of electric motor internal stator iron core double-end winding apparatus.This device has 1 transmission case, 2 winding heads; Transmission case has 2 feed wells and 2 groups of support wheels, and feed well is made of guiding epipleural, guiding forming board and guiding lower side panel; 2 winding heads are installed in respectively on transmission case and the corresponding position of feed well, and winding head has spring, stretches the pin cam, drive pin, driving-disc, shaping epipleural, forming board, guide card cam, shaping lower side panel and axle.But, to regulate owing to can't carry out trace external diameter size in unshakable in one's determination, the magnitude of misalignment that causes rolling up between each layer of lamination teeth groove is difficult to control in allowed limits.
The summary of the invention the purpose of this utility model is an external diameter adjusting device in a kind of electric motor internal stator wound core of design, in iron core is reeled the process of processing, realization is carried out the trace adjusting to external diameter size in unshakable in one's determination, and the magnitude of misalignment between each layer of volume lamination teeth groove is controlled in allowed limits.
The purpose of this utility model realizes by following approach.
The external diameter adjusting device is installed on the winding head unshakable in one's determination in the electric motor internal stator wound core of the present utility model, and winding head unshakable in one's determination has spring, stretches the pin cam, drive pin, driving-disc, shaping epipleural, forming board, guide card cam, shaping lower side panel and axle.
External diameter adjusting device in the electric motor internal stator wound core of the present utility model is characterized in that having the resilience regulating block, and the resilience regulating block is installed in the shaping lower side panel lower surface of winding head unshakable in one's determination;
1, described resilience regulating block is made of arc riser and flat board, have a screw hole on the flat board, the arc riser is fixed on the flat board, and its arc surface is with dull and stereotyped vertical, and the internal diameter of arc surface is not less than the diameter of winding head axle upper end, and central angle is 15～35 °; Cylindrical shape riser thickness is 1～4mm; Fixing hole and cylindrical shape riser axle center distance is than the big 5～40mm of axle upper end radius;
2, described resilience regulating block is fixed on the lower surface of shaping lower side panel with securing member, and laying angle is 0～30 °, and position angle is 18～22 °; When laying angle was 0 °, the working face circular arc was concentric with axle.
The resilience regulating block is by the lower surface of screw at lower side panel, and screw both can be locked the resilience regulating block, is again the gyroaxis of resilience regulating block, can regulate the laying angle of resilience regulating block; The utility model passes through to regulate the adjusting of the laying angle realization of resilience regulating block to external diameter size in unshakable in one's determination.When the resilience regulating block changes an angle counterclockwise, then laying angle strengthens, promptly outwards support the lamination after major coil is shaped, interior external diameter unshakable in one's determination is increased.By regulating the laying angle of resilience regulating block, obtain the interior external diameter of suitable volume lamination, then roll up between each layer of lamination teeth groove the magnitude of misalignment may command in allowed limits.
