Zusammenfassung:A numerically controlled (NC) flat capstan comprises a sliding block, a gear, a ball screw and an AC servo motor, wherein the AC servo motor is connected with a differential mechanism consisting of a planetary gear train and is also connected with a double ball screw through the gear and a bevel gear; the nut of the ball screw is connected with the sliding block of the flat capstan; moreover, the AC servo motor drives a pair of mesh gears connected with the ball screw; the ball screw is connected with a link stopper through a ball screw nut; in addition, a zero point switch, a forward limit switch and a backward limit switch are pressed and fixed on a main shaft box through the moving of the link stopper. The utility model can realize high locating precision and numerical control of cutting of the flat capstan.
