本文所述的万能弹簧卡盘,在车床加工的实际应用中,已证实了它的正确性。大家知道,现有的一些万能弹簧卡盘仅能以内表面或以外表面来装卡零件。本丈所介绍的卡盘是以内孔或外圆术面来装卡工件,并能保证达到零件的加工精度。高的传动系数也是此种卡盘的主要优点(所谓传动系数系指 The universal spring chuck described in this article has proved its correctness in the practical application of lathe machining. As we all know, some of the existing universal spring chuck only with internal or external surface to install parts. The introduction of the chuck is based on the inner hole or cylindrical surface to install the card workpiece, and can guarantee the accuracy of parts processing. High transmission coefficient is also the main advantage of such a chuck (the so-called transmission coefficient means
