现代飞机部件装配多采用自动化柔性制孔,自动化制孔单元是实现飞机部件柔性装配必不可少的硬件组成。工件零点的设置是以大型数控机床作为制孔设备的自动化制孔单元所的必要设置步骤。使用激光跟踪仪作为测量设备,在机床坐标系、数模坐标系与工装坐标系间建立联系,实现了机床工件位置、数模工件位置与产品实际位置的统一,为实现飞机部件装配的自动化柔性制孔奠定了基础。该方法在某型飞机柔性装配过程中得到了验证运用,验证了方法的可行性。 Modern aircraft parts assembly and use of automated flexible multi-hole, automatic hole making unit is the hardware components necessary to achieve flexible assembly of aircraft components. Workpiece zero setting is based on a large CNC machine as a hole making equipment necessary for the production of porous unit setup steps. The use of laser tracker as a measuring device in the machine tool coordinate system, digital and coordinate system and the tool coordinate system to establish contact between the workpiece position of the machine tool to achieve the unity of digital workpiece position and the actual position of the product, in order to achieve the flexibility of assembly of aircraft parts flexibility Pores laid the foundation. The method has been verified and applied in the flexible assembly process of a certain aircraft, which verifies the feasibility of the method.
