气门摇臂轴支座的机械加工工艺及夹具设计.docx

摘要
机器加工行业作为一个传统而富有活力的行业，近些年取得了突飞猛进的生长，在新经济时代，行业出现了新的生长趋势，由此对其它的质量，性能要求有了新的变革。现在机器加工行业产生着结构性变革，工艺工装的设计与改进已成为企业生存和生长的须要条件，工艺工装的设计与改进将直接影响加工产物的质量与性能。
首先介绍了气门摇臂轴支座的作用和工艺阐发，其次确定毛坯尺寸，然后进行了工艺规程设计，最后进行夹具设计。通过对气门摇臂轴支座进行研究，来进行加工工艺和夹具设计，气门摇臂轴支座零件为铸件，具有体积小，零件结构简朴的特点，由于面比孔容易加工，所以在制定工艺规程时，就接纳先加工面，再以面为基准来加工孔的要领，其中各工序夹具都接纳专用夹具，其机构设计简朴，方便且能满足要求。
要害词：气门摇臂轴支座；工艺阐发；工艺规程设计；夹具设计
