为了扩大普通活络顶尖在车床上的应用范围,适应不同工件的加工要求,实践中,我们设计了如图1所示的多功能活络顶尖工具套,经多年使用,效果很好,现介绍如下:多功能活络顶尖工具套是根据支顶不同工件需要设计制作的。孔径d与活络顶尖前部的台阶滑动配合,60°内锥孔与顶尖60°外锥面相吻合。使用时,根据需要将选择好的工具套套在活络顶尖台阶前部(图2),摇动尾架手轮顶 In order to expand the general application of the top activities in the lathe to adapt to the processing requirements of different parts, in practice, we designed a multi-function active top tooling shown in Figure 1, after years of use, the effect is very good, are as follows: Multi-function active top tool kit is based on the support of different parts of the need to design and manufacture. The aperture d is in sliding fit with the step on the front of the active top, and the inner cone of 60 ° coincides with the outer cone of the top 60 °. Use, according to the need to choose a good set of tools in the top of the active top steps (Figure 2), shake the tailstock hand wheel top
