立卧式33轴组合钻床上主轴箱设计
摘要
机械制造装备的发展是机械工业最主要的环节，目前，机械加工对精度要求越来越高，机械工厂为了降低加工成本，提高加工质量，导致组合机床在制造业中应用越来越广，并已显示出巨大的优势。本组合机床主要是保证被加工零件的尺寸精度和位置精度要求，高速高效地完成对缸体的加工，设计了本组合机床。在设计过程中借鉴了国内外一些现有的组合机床设计资料。在组合机床的设计中，主轴箱加工工艺是关键。“三图一卡”包括加工零件工序图，加工示意图，机床总图，生产效率计算卡，在此基础上，绘制了上主轴箱设计的原始依据图，拟订了主轴箱的传动路线，应用最优化方法布置齿轮。确定传动参数，绘制了上主轴箱装配图、箱体补充加工图，进行了轴、齿轮等零件的强度校核。较好地完成了设计要求，在提高了产品质量的前提下，提高了效益。大体掌握了组合机床的制造过程。
组合机床上主轴箱的基础环节是绘制上主轴箱树形图，主轴箱属性图实际上是借鉴了通用机床主传动系统设计中使用的转速图、结构图经演化而得。由于主轴箱传动系统是一个原动件带动多个从动件，没有变速机构，而传动路线条数却很多，出现许多分支。从图形上看，驱动轴相当于树根，各主轴及油泵轴均为末端件，相当于各条树枝的末梢，故形象地命名为“树形图”。
