In this paper

the application and study of three jaw structure material spindle of a kind of semiautomatic winding machine is introduced. The material with various widths is suitable to the loading structure of the three jaw structure material spindle within the designed width range. The coaxiality improvement of coil and material axial by the loading structure of three jaw structure material spindle is described through the circular run out comparison of the same coil which is loaded on the material spindles with two structures

thus reducing the winkle due to unreasonable loading structure during the winding period. The production cost for the three jaw structure material spindle of semi-automatic winding machine is less and is a good choice for enterprise who wants not only to improve the element’s quality

but also to reduce the investment cost of equipment.
