气缸体双工位专用钻床总体及右主轴箱设计 摘要 为了提高气缸体的加工精度和生产效率，课题设计了一台双工位专用钻床。该钻床一共要加工43个孔，分别为左面钻削12×Φ30深110的挺柱孔；右面扩12×Φ41、锪挺柱孔Φ41端面，并钻削顶面12×Φ8和7×Φ6的水孔。该机床设计包括总体设计和右主轴箱设计两部分。总体设计包括机床配置型式的确定、结构方案的选择以及“三图一卡”的绘制。考虑到加工方便，该床采用卧式双工位加工的方案。加工和装配的工艺性好，零件装夹方便。采用机械滑台实现刀具进给，借助导套引导刀具实现精度稳定的加工。主轴采用标准主轴，刀具选用复合麻花钻，使得工序集中。右主轴箱设计包括绘制多轴箱设计原始依据图、拟定主轴箱的传动路线，确定主轴和齿轮，并对轴和齿轮的强度校核计算，最后绘制多轴箱装配图和零件补充加工图。本组合机床加工效率高,减轻了工人的劳动强度,提高了生产效率。 关键词: 钻孔；主轴箱；气缸体；组合机床 Abstract: To improve the cyli
