1、机械设计毕业设计论文答辩ppt模板篇一：机械专业毕业设计范本毕业设计说明书题目：壳体零件的加工工艺规程及其夹具设计学号：姓名：班级：专业：机械设计制造及其自动化指导教师：学院：答辩日期：毕业设计说明书摘要18本设计是一种壳体的工艺设计和夹具设计。该零件是一种支承和包容传动机构的壳体零件。设计中先进行零件的结构和工艺分析，确定粗基准和精基准以及零件的加工余量与毛坯的尺寸，得出零件的加工工艺过程，接着再计算各工序的切削用量以及工时。除此之外，还设计了一套专用车床夹具和专用钻床夹具。首先确定合适的定位基准，设计夹具体，再选择定位元件、夹紧元件等部件

2、。然后计算出定位误差、夹紧力以及切削力，分析夹具的合理性。最后对关键部位进行Proe有限元分析，确保夹具可以安全的工作。关键词：壳体；工艺分析；车床夹具；钻床夹具；有限元分析I毕业设计说明书AbstractThisdesignisaprocessdesignandfixturedesignoftheshell.Thissectionisashellofsupportingandembracingtransmissionmechanism.Inthedesign,itshouldfirstprocessthestructuralandindus
