气缸体双工位专用钻床总体及左主轴箱设计
摘要：本设计主要针对气缸体左、右两个面上43个孔的多工序加工、生产效率低、位置精度误差大的问题而设计的，从而保证孔的位置精度、提高生产效率，降低工人劳动强度。课题设计了一台气缸体双工位专用钻床。用于钻削气缸体一侧面上12×∅30深110的挺柱孔，另一侧扩12×φ41、锪挺柱孔φ41端面，并钻削顶面12×φ8和7×φ6的水孔。该机床设计的重点是总体设计和部件设计两部分。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。部件设计包括绘制左主轴箱设计原始依据图、确定主轴和齿轮、完成动力计算、设计传动系统、绘制多轴箱装配图和零件补充加工图。机床采用卧式双工位两面加工的方案，加工和装配工艺性好，零件装夹方便。采用液压滑台实现刀具进给，借助导套引导刀具实现精度和稳定的加工。主轴采用标准主轴，刀具选用复合麻花钻，使得工序集中。
