一、前言刀具拉紧装置是将刀具在主轴锥孔中定位后拉紧用的一种功能部件。它除应用在加工中心主轴上,以便实现其频繁更换刀具的要求外,也可用于有类似要求的其它的机床主轴上。目前我国刀具锥柄部分已经实现了标准化,为实现刀具拉紧装置的系列化奠定了基础。此类功能部件的系列化设计和专业化生产将改变我国分散设计与制造拉紧装置的局面。产品系列化设计的关键是正确与合理地选定主参数。刀具拉紧装置的主参数为最大拉紧力(简称拉紧力),因此参数能反映出
First, the foreword Tool tightening device is the tool in the spindle taper hole after positioning with a functional part. In addition to its application in the machining center spindle, in order to achieve its frequent replacement tool requirements, but also for other similar requirements of the spindle. At present, the taper shank part of our country has been standardized and lays the foundation for the serialization of the tool tensioning device. The serialized design and specialized production of such functional components will change the situation of decentralized design and manufacturing of tensioning devices in China. The key to product serialization design is to select the main parameters correctly and reasonably. The main parameter of the tool tightening device is the maximum tightening force (short tightening force), so the parameters can reflect
