1、.摘要在机械制造各行业的工艺过程中广泛应用着各种不同的，用以固定加工对象，使之占有正确位置，以便接受施工的一种工艺装备，统称为夹具。因此，无论是在机械加工，装配，检验，还是在焊接，热处理等冷，热工艺中，以及运输工作中都大量采用夹具。但在机械加工中应用最为广泛的是金属切削机床上使用的夹具，我们称其为机床夹具。它在保证产品优质，高产，低成本，充分发挥现有设备的潜力，以便工人掌握复杂或精密零件加工技术，以减轻繁重的体力劳动等诸方面起着巨大的作用。因此，机床夹具的设计和使用是促进生产迅速发展的重要工艺措施之一。为此，在本次毕业设计时，选择了机床夹具设计。本文主要围绕机床钻孔夹具设计为中心。用以

2、钻HBC6700方向机壳体，首先通过参观实习让我们对夹具设计有了初步的了解，特别是对盖板式钻模夹具设计的了解更为深刻。然后，在导师的指导下，对夹具设计方案进行分析和选择。选定方案后，通过查阅相关夹具设计书籍和相关图例在钻孔夹具设计过程中，在查阅了相关文献后完成外文翻译。参考相关资料完成夹具的总体设计。关键词：关键词：机械；夹具；钻模；加工...目录摘要·····································......................................................................1前言·········
