1、本科机械毕业设计论文CAD图纸 QQ 401339828 摘 要（一）电机机座钻孔组合机床是大型组合机床，它的配置型式具有固定式液压夹紧的单工位组合机床，这类组合机床夹具和工作台都是固定不动的，动力滑台实现进给运动。滑台上的动力箱实现切削运动，根据工件结构特点，以及精确要求，采用结合面为定值基准面。 在基准面对应的另一圆柱面上，用压块压紧，由于结合面的加工精度较高，以它为基面，完全可以达到要求的加工精度。（二）几何机床总体设计-三图一卡“被加工零件工序图”它是组合机床的设计的主要依据，它是制造使用，检修和调整机床的重要技术条件绘制加工示意图，它是刀具夹具，多轴箱，液压电器装置设计及通用部件选择
2、主要原始资料，它是调整机床，刀具及试车依据。绘制联系和运动关系及检验机床各部件相对于位置及联系是否满足加工要求，通用部件的选择是否合适，并为进一步开展主轴箱，夹具等专用部件，零件的设计提供依据。相对生产率计算卡，它用来反映机床的加工过程，完成这一动作所需要的时间，切削用量，机床生产率及机床负荷率。(三)组合机床主轴箱设计，按专用要求进行设计，由通用零件组成，其主要作用是根据被加工零件的要求，安排各主轴位置并将动力和运动由电机或动力部件传给各主轴，使之得到要求的转速，机床主轴箱选用400*400,用中间传动轴带动主轴传动。（四）夹具设计 在前述定位基准面选择的前提下，用摆动式压板杠杆夹紧结构，夹
