Auxiliary device to solve the shortcomings of the winding is not solid.

In view of this, one of the main purposes of the improved fixture of the creator of this case is to adopt the axial two-end guiding structure, even if the number of coils is large, the volume will not be excessively expanded, which can reduce the length of the conductive wire and relatively reduce the manufacturing cost. It can also facilitate the installation of zero (group) parts, effectively solving the drawbacks of loose winding of conductive wires.

Secondly, the winding machine equipped with the creative fixture can automatically produce a stator with a large number of turns and no over-expansion. The yield is better than the prior art, and naturally has better market competitiveness.

In this way, the fixture of the present invention is sufficient to limit the orientation of the conductive line by the second arc portion of each slider and the first arc portion of the reference member forming the axial end guiding structure, and the volume is not even if the number of coils is large. Excessive expansion can not only reduce the length of the conductive wire, but also reduce the manufacturing cost, and can facilitate the installation of zero (group) parts, effectively solving the disadvantages of loose winding of the conductive wire.
