1、本科机械毕业设计论文CAD图纸QQ401339828摘要本课题是法兰盘卧、斜轴回转分度钻床夹具设计,许多功能完全相同而结构工艺性不同的零件,它们的加工方法与制造成本有着很大的差别,应仔细审查零件的结构工艺性,定位基准选择、加工方法选择。根据零件主要表面的技术要求、生产类型、材料的性能、零件的结构、形状尺寸、毛坯尺寸、毛坯情况、生产计划安排及现有的对比,确定其最佳夹具加工方案。本设计中,根据法兰盘尺寸公差、形状和位置公差、表面粗糙度、技术要求、工件材料、等要求来设计夹具过程。根据给定的生产量大小来确定夹具类型过程。根据现有生产条
2、件,充分发挥现场技术条件手段和技术力量的潜力来设计夹具过程。机床夹具的总体设计包括从方案制定到总装配图的设计的全部过程。包括确定工件的定位,选择或设计定位元件,计算定位误差;确定刀具的导引和对刀方式,选取或色痕迹导引元件或对刀元件;确定工件的夹紧方式,选择或设计夹紧机构或装置,计算夹紧力;确定夹具体及其他装置的结构类型等。通过合理的设计,在保证零件加工质量前提下,提高生产效率,降低消耗,以取得较好的经济效益和社会效益。关键词:夹具,法兰盘,回转分度定位Ⅰ本科机械毕业设计论文CAD图纸QQ401339828AbstractThe
