读了《机械制造》1990年第12期上刊登的“拉力弹性顶尖”一文,很受启发。结合本人的实践对其结构作了改进。以供广大读者作参考.改进后的结构如图所示,该结构利用普通的弹性顶尖,不用制作专用轴承,从而降低了制作的要求,并且使用效果良好。安装时,先装上普通顶尖,再装上螺锥套4、单向推力球轴承6、弹簧8、连接套7、端盖9和连接套13及支承套10,再锁紧螺母1.弹簧8要求在微量变形时能产生较大的拉力。 Read the “mechanical manufacturing” in 1990 the twelfth issue of “flexible top” article, very inspired. Combined with my own practice, the structure has been improved. For the majority of readers for reference.An improved structure as shown in the figure, the structure of ordinary flexible top, without making special bearings, thus reducing the production requirements, and the use of good results. When installed, first install the ordinary top, and then install the screw sleeve 4, one-way thrust ball bearings 6, spring 8, connecting sleeve 7, cover 9 and connecting sleeve 13 and bearing sleeve 10, and then tighten the nut 1. Spring 8 requirements in the micro deformation can produce greater tension.
