摘要
零件的工艺编制，在机械加工中占有非常重要的地位，零件工艺编制得合不合理，这直接关系到零件最终能否达到质量要求；夹具的设计也是不可缺少的一部分，它关系到能否提高其加工效率的问题。因此这两者在机械加工行业中是至关重要的环节。本次设计是在学完 机械制图 、 、 机械制造技术基础 、 机械制造装备 等专业课后，掌握了一定的专业知识。把所学的理论知识综合地运用在实际工艺、夹具设计中。
本次设计的是减速箱箱体上的孔6- 13锪平 30的加工工艺以及夹具的设计，在编制加工工艺时，要考虑到孔的各项精度以及形状与位置公差等。
在设计加工孔6- 13锪平 30的专用夹具时，以箱体底面为基准，通过“C”形钳将箱盖和箱座联结，并以定位销将其定位。为了缩短辅助时间，采用了可换钻套,钻模板左端采用一铰链使其翻转,右端也用铰链和一开口垫圈,用螺母进行联结。这样能很快将箱体放入夹具体上,减轻工人劳动强度，大大提高生产率，提高效益。
关键词：工艺、基准、辅助时间、定位、形位公差。
