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。
