摘要: 为实现航空发动机燃油喷嘴组件内腔锥角的快速精确检测，在双球法锥角测量原理的基础上，基于三轴运动平台、直线位移传感器、浮动夹头和多轴运动控制器等搭建了一套喷嘴内腔锥角精密测量系统，以解决喷嘴内腔锥角的自动化测量难题。该测量系统采用紧凑的立柱式结构，其运动机构由X、Y和Z直线轴构成，控制系统采用主流工控机与专用多轴运动控制器相结合的二级位置闭环数字复合控制方式，并且设计了具有"自适应入孔"功能的新型双球锥孔测头。最后，应用该测量系统对3个圆锥孔零件和某喷嘴样件的内腔锥角特征分别进行了多次重复测量。实验结果表明，所搭建的测量系统能够完成既定的测量任务，而且系统的测量精度指标能够满足检测任务需求，因而可以作为一项喷嘴结构尺寸检测的技术解决方案。Abstract: In order to achieve the goal of rapid and accurate inspection of the inner cone angles of fuel nozzles in the aero engine, a precision measuring system for this parameter is built up according to the measuring principle of two spheres. Based on the three-axis motion platform, linear variable differential transformer, floating holder and multi-axis motion controller etc, the system could be utilized to solve the automatic measurement of the inner cone angles of fuel nozzles. In the measuring system, the compact column structure is adopted and the motion mechanism is composed of X, Y and Z linear axes. At the aspect of the control section, the digital composite control mode of position closed loop of two levels is employed, which is based on the combination of the mainstream industrial computer and the special programmable multi-axis controller. Also, the new special probe for the inner cone angle is designed on account of the floating entry technology. Finally, the inner cone features of three work-pieces and a fuel nozzle are measured several times on the measuring system established. The experimental results show that the system could accomplish the appointed measuring task and the measuring accuracy for meeting the inspecting requirements. Therefore, the precision measuring system for inner cone angles of fuel nozzles could serve as a solution for the measurement of the shapes and dimensions of fuel nozzles.
