摘要本文主要介绍了镗铣舵叶法兰面及孔的专用机床的设计，在该机床上可以完成镗孔、扩孔、铣削和磨削等多道工序，生产所需消耗的时间将大大降低，加工精度将有很大的提升，并且有利于保证加工精度的稳定性，能节约大量的社会资源。根据设计要求确定采用卧式主轴的布局方案，先对主运动进行设计，确定机床的主参数和切削用量；后对其他三条传动链进行设计，包括滚珠丝杠的计算、选用和校核，电动机的计算与选型，齿轮副的设计与校核；最后对主轴箱进行三维建模。本机床具有原理正确、加工精度高、加工效率高、减轻劳动强度、极大缩短加工时间和降低加工成本的众多优点。通过传感器等纯自动化的操作，避免了人工参与（装夹、对刀、打磨、试配等）的麻烦和精度难以保证的缺点。由于本机床本身没有专用夹具，是通过划线调整和千斤顶等工具将舵叶移动到加工位置，所以经过简单的调整，即可改装为其他专用机床，用于其他大型零件的法兰面或孔的加工，使本机床具有了很高的实用价值和推广意义。86943

Abstract    This paper mainly introduces the design of special machine for boring and milling rudder flange blade surface and hole。 In this machine can finish boring and reaming, milling and grinding, etc。 multi-channel processes, production efficiency and precision are improved greatly, and improve the machining precision and stability, and save social resources。 According to the design requirements, to determine the horizontal spindle layout scheme, first of the spindle box design, determine the parameters and transmission scheme of machine tool; on the other two drive chain design; finally carries on the design to the bed, which comprises a support, guide rail, a lead screw design and selection, positioning of motor and spindle box, screw and nut connection aspects。 The machine has the advantages of correct principle, high processing precision, high processing efficiency, reduce labor intensity, greatly shorten the processing time and reduce the cost of processing。 Avoid the shortcomings of the trouble and the accuracy of the artificial participation (clamp and cutter, grinding, test, etc。) to ensure, through the sensor to the pure mechanical operation。 Because the machine itself has no special fixture, the rudder blade is moved to a processing position through the marking adjustment and Jack tools, so after a simple adjustment, can be modified for other special machine tool for processing of other large parts of the flange or a hole is the machine tool has the very high practical value and significance of generalization。
