机翼喷丸壁板数字化柔性检验关键技术研究

Key Technology of Digital Flexible Inspection for Wing Shot Peening Panel

在飞机机翼喷丸壁板的检验过程中,利用点阵化三坐标数控定位技术对飞机机翼喷丸壁板非检测部位进行柔性定位支撑,并施加壁板检验所需的外部压力;通过三坐标数控定位器上部的力传感器测量壁板检验允许施加的外部压力,利用高精度的测距传感器在平面内的两自由度移动对飞机机翼喷丸壁板检测部位进行测量,测量数据实时反馈回数据库,将数据模拟成数学模型与检测数学模型进行比对,测量位置的实际差值即为检验产品的制造误差;检测完成后,计算机软件自动生成检验报告。

In the inspection process of the shot peening wing panels, on the Non detection area of the panels is support by the three axis CNC locators, and applying required external pressure on panel; measuring the external pressure by the force sensor on the three axis CNC locators, measuring the surface of panel by the ranging sensor,t he sensor can move two degrees of freedom in plane. The measurement data are real-time feedback to the database, then the data are simulated to the actual mathematical model and are compared to the theory mathematical model, the actual difference of measurement location is manufacturing error;after the completion of the inspection, report are automatic generated by computer software.
