摘要：组合机床是以通用部件为基础，配以少量专用部件，对一种或若干种工件按预先确定的工序进行加工的机床。汽车变速箱体有前后两个端面需要进行孔加工，为了提高效率，我们采用双面钻孔组合机床对它们同时进行加工。双面钻孔组合机床是针对在工件两相对表面进行钻孔加工而设计的一种高效自动化专用加工设备。本书为EQ-140汽车变速箱后端面钻孔组合机床设计说明书，着重介绍了变速箱体后端面钻孔专用组合机床设计过程，包括总体方案的制定，组合机床工序图、加工示意图、尺寸联系图及生产率计算卡的绘制（即三图一卡），多轴箱传动与结构的设计以及夹具的设计及液压原理图和PLC控制图的设计。 关键词：组合机床,设计 Abstract: The modular machi
