A421定位盘加工工艺编制及钻孔夹具设计 【摘要】定位盘的专用夹具设计，其介绍了专用夹具的一般设计原则。设计原则与设计方法来看，几乎所有的机械产品都遵循这些规则。不同的公司，不同的客户要求，不同的专用夹具精度，不同的加工工艺，虽然都有其不同的设计理论与设计依据，其中大部分规则，方法都是相通。本设计前期我主要介绍了专用夹具的准备工作，之后又讲述了专用夹具设计的理论知道及其常用的软件与设计技巧，接着介绍了定位盘镗孔夹具设计主要过程与参考，中间配插了专用夹具设计参数化实体图片。总的来说，专用夹具无外乎包括三大机构：定位机构、夹紧机构和引导机构。在介绍定位机构时，重点介绍了定位机构的常用定位元件大小及使用原则。具体设计请查看定位盘夹具设计工程图，里面很多参数化设计与设计依据与上面介绍的大体相同。有些地方，设计原则与设计方法是死，运用在不同的产品或产品的不同地方，会稍做调整。活学活用所学习的知识，才能更快的适应新时代产品的夹具设计。随着产品设计师技术水平的提高，随着夹具加工工艺的改进，夹具加工设备更新换代，夹具结构只能越来越人性化，越越高精专化，夹具人才的含金量也会越来越高。 【关键词】定位盘；夹具设计；设计原则 A421?positio
