1、机夹式深孔刀具设计摘 要：深孔加工作为二战以后发展起来的一种新型加工工艺，在国民经济发展中发挥着越来越巨大的作用。然而，由于我国深孔加工技术起步较晚，发展不容乐观。本文研究了深孔加工原理。并针对难加工材料钛合金设计了适合加工中小直径深孔的刀具。本文重点在于分析深孔加工过程尤其是深孔钻削过程的工艺特点。初步地对深孔加工工艺特点进行分析。同时立足于石油石化行业，针对当前行业内对钛合金材料的深孔产品的需求，选择难加工材料钛合金作为加工对象。本文介绍分析了目前国内外深孔刀具现状，指出了焊接式深孔钻的缺点。针对焊接式深孔钻的缺点提出了机夹式深孔钻结构。并选择具有代表性的尺寸进行结构设计。提出了适合小直径
2、深孔加工的紧凑型刀具和适合中等直径加工的普通型刀具。针对目前国内深孔机床造价昂贵，装备周期长的问题。本文提出并初步尝试了把普通车床改造为深孔机床的改造设计方案。关键字：深孔刀具；内排屑深孔钻；深孔镗刀；钛合金；机夹式Design of Clip-on Deep Hole Machine ToolAbstract：Deep-hole drilling processing, as a new processing technology developed after World War II , is playing an increasingly significant role in nat
