为了轴类、管类、套类霉件的车、磨加工,我们设计了一种比较理想的组合顶尖(图1)。这种顶尖既可使被加工零件自动定心,又可承受在切削过程中刀具对工件的切削扭矩,因而担负着定心和传递扭矩的双重任务。使用这种新式组合顶尖,既方便,又省工省时,可实现不停车快速装卸零件。凡两端有中心孔或中心锥的轴类、管类、套类零件的外圆加工均可采用这种顶尖。 In order to shaft, tube type, set of mold mold car, grinding, we designed an ideal combination of the top (Figure 1). This kind of top not only can make the machined parts self-centering, but also can bear the cutting torque of cutting tools on the workpiece during the cutting process, thus shouldering the dual tasks of centering and transmitting torque. With this new combination of tops, it’s convenient, saves time and effort, and allows quick parts handling without stopping. Where both ends of the center hole or center cone shaft, tube, sleeve parts of the outer circle machining can use this top.
