图1为以工件内孔定位内锥螺纹张力心轴,图2为以工件外圆定位锥螺纹心轴。通过旋转锥螺杆(或锥螺母),使内(外)锥螺纹套在心轴径向产生向外张力(或向内缩力),对工件有定心和夹紧作用。
Figure 1 to the inner hole of the workpiece positioning taper thread tension mandrel, Figure 2 to locate the outer cylindrical workpiece taper thread mandrel. By rotating the conical screw (or cone nut), the inner (outer) taper thread sleeve generates radial outward force (or inward shrinkage force) in the radial direction of the mandrel to center and hold the workpiece.
