Abstract

The invention discloses a high-precision spindle of a braiding machine. The spindle integrates a thread-unreeling clutch unit, a strand brake unit and a tension adjusting unit into one; a unidirectional bearing is additionally installed on bobbin column in particular; when a thread-carrying spool is counter rotated, a loose strand can be easily and rapidly reeled; ball type transmission is applied in clutch and brake units for the first time, and such a structure has the characteristics of high cooperation precision, small workpiece wear, fast operation speed, uniform thread unreeling amount and low work noise and is especially applicable to high-speed braiding; the tension adjusting unit realizes stepless adjustment of tension by changing pretightening force of a tension spring through rotation of a tension adjusting nut, which enables a tension adjusting range to be wider and more accurate, so product quality and work efficiency can be greatly improved; thus, the high-precision spindle of the braiding machine has a wider application scope.
