摘　　要：航空碳—碳复合材料X射线数字成像检测装置是供航空制造业中小型关键复合材料零部件X射线检测的设备。依据被检测产品的特点,该装置设计有前后、左右、上下六个自由度,可实现旋转、倾斜等运动形式。其传动系统采用步进电机和伺服电机驱动;谐波减速机、蜗杆减速机减速;滚动轴承支承、滚动直线导轨导向;滚珠丝杠、齿轮传动的方式。控制系统采用模块化结构的PLC控制,完成具体的运动执行控制。速度调节范围为0.1～3.0m/min,定位误差≤0.2mm,电机联动误差≤1ms(一个PLC程序扫描周期),根据被检工件的检测要求实现了实时多角度、全位置X射线数字成像检测。X-ray digital imaging detection device of aeronautic carbon-carbon composite is X-ray inspection equipment for the small and medium- sized pivotal composite material parts in the aeronautic manufacturing industry. In accordance with the characteristics of the detected product, six degrees of freedom of the front and back, left and right, up and down is designed, it can realize forms of movement of rotation and inclination. The transmission system adopts stepper motor and servo motor to drive, harmonic reducer and worm reducer to decelerate, rolling bearings to support and rolling linear guideway to guide, ball screw and gear to transmit. The control system uses a modular structure PLC control to complete the implementation of the specific motion control. In the device, the speed regulating range is form 0.1 to 3.0m/min, the positioning error is less than 0.2mm, the motor linkage error is less than lms （ a PLC program scan cycle）. According to detection requirements of detected workpiece, real-time muhi-angle and all-position X-ray digital imaging detection is achieved.
