直驱摆头动力刀架系统是动梁无滑枕立式铣车复合加工中心的关键技术之一,该系统采用先进的直驱技术代替了传统的传动方式,直驱技术虽然有效的增高了机械的效率,但功率损耗和电气损耗也随之提高.针对动力刀架系统,通过“机械机构、控制系统、切削过程”三方面的耦合计算,提出了一种采用功能转换原理进行机电耦合系统分析的方法,得出直驱摆头动力刀架系统的最佳机电耦合系数.有效地增强系统的稳定性,提高摆头刀架的加工精度,并在一定程度上优化了系统.%The direct-drive rotary spindle head dynamic turret system is one of the moving beam without ram vertical milling-lathe complex machining center s key technologies. It uses advanced direct -drive technology instead of the traditional transmission way. The direct-drive technology increases mechanical efficiency effectively. However, power loss and electrical loss also increases. Aiming at the dynamic turret system, by using the coupling calculation of mechanism, control system and cutting process, it presents electromechanical coupling system analysis method used by the function conversion principle, and gets the best electromechanical coupling coefficient of the direct-drive swing power tool system. It enhances the system s stability effectively, and improves the machining accuracy of the dynamic turret, and optimizes the system to a certain extent.
