蜂窝结构的焊点位置控制方法研究

蜂窝结构是航空发动机中的重要封严结构,随着航空航天工业的飞速发展,该结构的需求也日益增多。蜂窝拼焊的自动化生产是实现蜂窝结构高效率生产的有效方法之一。针对蜂窝结构自动化生产中的关键问题,即焊点的位置精度,分析了原有工艺和系统的不足。在基于ACR9000运动控制器平台上,针对焊点精度,分别提出了基于电机编码器的位置控制和轴同步原理的方式。结果证明,这两种方法能够很好地实现焊点位置的精度要求,使蜂窝高质量高效率生产。

Research on Position Control Method of Welding Spot of Honeycomb-Structure

Honeycomb-structure is an important sealing structure of the aeroengine,and the demand is increased with the development of aeronautics and astronautics.The automation of tailor welded honeycomb is one of effective way to realize the high efficiency production of honeycomb.In this paper,the position accuracy of welding spot which is the key problem during automatic process of honeycomb and the disadvantage of original process and control system are analyzed.Two kinds of position control mode under ACR9000 are proposed to make welding spot accuracy:one is based on the motor encoder;The other is based on multi-axis synchronization.The results showed that two methods can achieve the requirement of position accuracy of welding spot,and can ensure high quality and high efficiency production of honeycomb.
