摘　　要：针对航空发动机中薄壁细长轴类零件的壁厚需要精密高效测量的问题,提出了一种双测头快速高精度测量方法。该方法以大长径比碳纤维测杆支撑小型非接触光学测头进行细长轴内壁测量,以龙门式框架安装接触式测头同时进行细长轴外壁测量,并采用高精度气浮平台作为工作台带动零件移动,从而实现对细长轴类零件的壁厚进行测量。采用该方法研制了测量设备,并详细介绍了机械、电控和软件设计。通过实验和第三方检测,该测量设备可对长度1 500 mm、内孔直径14 mm的细长轴进行壁厚测量,验证了本方法的有效性。Aiming at the measurement of the wall thickness of thin-walled slender shaft parts in aero-engine,a fast and high-precision measurement method of dual probe is proposed.A small non-contact optical probe in the present method is used to measure the inner wall of a slender shaft with a large length diameter ratio carbon fiber pole,and the contact type head is installed in the gantry structure to measure the outer wall of the slender shaft at the same time,and the high precision air floating platform is used as the worktable to measure the wall thickness of the slender shaft parts.The measurement equipment is developed by using the present method,and the mechanical,electronic control and software design are introduced in detail.Through the third party detection,the device can measure the thickness of the slender shaft with a length of 1 500 mm and an inner hole diameter of 14 mm,and the effectiveness of the method is verified.
