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
2、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IAbstractMachinerymanufacturingindu
