CC2105轴承座工艺分析及钻4-Ф11均布,沉孔Ф17深10孔夹具设计
摘要
专用夹具设计是每一个理工科学生必不可少的。本文设计的任务是CC2105轴承座工艺分析及钻4-Ф11均布,沉孔Ф17深10孔夹具设计。对零件的构造完全了解后,将毛坯的大小,加工方法,还有基准,加工的工艺路线都确定下来;之后按照事先设定的加工工艺路线,将粗基准,还有精基准分开,计算每一道工序的相关数据。
本次专用夹具设计是钻4-Ф11均布,沉孔Ф17深10孔。专用夹具设计的目的是将停机的时间缩短,提升生产率。夹具设计经过问题的提出;定位、夹紧方案还有装置的确定,加工时切削力等等。最后,绘制夹具装配图及所有非标零件图等。
设计夹具最关键是结构的合理性、工艺性,本次设计的夹具构造简单,紧凑,操作简单灵活。
