The invention provides an electromechanical actuator for four-redundancy laser measurement, which comprises a first laser generating and detecting end assembly, a second laser generating and detecting end assembly, a laser generating and detecting end assembly sealing gasket, a laser generating and detecting end assembly cover plate, a power motor, a dustproof end cover, a ball screw pair, a screw pair screw, a shell and a first rotor reflecting vertical angle, a second rotor reflection vertical angle, a four-redundancy laser displacement sensor electric connector, a motor weak current connector, a motor strong current connector, an A connection support lug and a B connection support lug. Through independent main-main design of four redundancies and non-contact measurement, high reliability of displacement feedback of the electromechanical actuator is realized, and the problems that the redundancy of displacement measurement of the actuator is less and the actuator is easy to damage due to contact friction are solved; the four-redundancy laser measurement range is wide, the displacement measurement range can cover the micrometer level to the meter level, the measurement precision is high, and the test precision can reach the submicron level.

    本发明提供一种四余度激光测量的机电作动器,包括:第一激光发生探测端组件,第二激光发生探测端组件,激光发生探测端组件密封垫,激光发生探测端组件盖板,动力电机,防尘端盖,滚珠丝杠副,丝杠副丝杆,壳体,第一动子反光垂直角,第二动子反光垂直角,四余度激光位移传感器电连接器,电机弱电连接器,电机强电连接器,A连接支耳,B连接支耳。通过四余度皆为独立的主主设计和非接触式测量,实现了机电作动器位移反馈的高可靠性,解决了作动器位移测量余度少和接触摩擦易损坏的问题;四余度激光测量范围广,位移测量范围可覆盖微米到米级,测量精度高,其测试精度可达亚微米级。
