1、题学系专业学指导川理工学院毕业设计(论 文)说明书目 c615车床进给箱加工工艺及其链孔夹具设计生冯康平别机电工程系班级2003级机制3班号2003111025教师 刘 珠摘要零件的加工工艺编制,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。C615车床是现代制造业常用的机床之一,本零件为进给箱是c615车床六大组成部件之一,它位于机床的中前端,主要安装进给变速机构,它的作用是把从主组经挂轮机构传来的 运动传给光杆和丝杆,取得不同的进给量
