摘　　要：针对目前国内船用可调距螺旋桨(简称调距桨)制造中落后的手工打磨工艺现状,提出了一种利用数控砂带磨削技术实现调距桨复杂型面的高效加工方法,并设计了四坐标联动的强力磨床,重点介绍了该磨床的关键技术如强力砂带磨头的设计、调桨砂带磨削数控编程软件的开发等,最后利用该样机对桨叶表面进行了强力砂带磨削应用试验,为确定合理的船用螺旋桨强力高效砂带磨削工艺参数与应用提供了参考依据。Aiming at the backward hand-grinding ways of controllable pitch propeller in China shipbuilding industry,a highly efficient precision grinding method is brought forward,and a four axes simultaneous grinding machine is designed which can machining complex profile with abrasive belt grinding technology by CNC.The key techniques to develop this new grinding machine is presented in detail such as heavy-duty belt grinding head,NC grinding computer aided software,etc.The application experiments of grinding and polishing propeller blade are carried out on the basis of different parameters,and the trial results provide foundation for the confirmation and application of reasonable belt grinding and polishing parameters.
