摘要
介绍了一种挠性陀螺接头的精密装配方法和实验.首先对现有的陀螺装配方法和存在的问题进行了总结,建立了内外挠性接头装配后所形成的十字型铰链模型.利用伪刚度理论对该模型进行了分析,以此为基础分析了陀螺接头装配过程中的误差产生机理,提出了基于显微视觉图像分析结合力传感控制的陀螺接头装配系统.采用模块化设计思想,对装配系统中的精密定位、显微视觉和控制系统等关键技术分别研究,最后将单元技术集成,并进行了实验.装配的各项指标精度可以达到5μm.
A precise assembling method and experiments for the flexible gyro joints is described in this paper. Some existing assembly methods of gyro and the problems in them are summarized. Across model including an inner and an outer flexible is established. The influence curve of the two flexible connector hinges' relative position is achieved by analyzing the model with the Pseudo-Rigid-Body Model. The error principle in the process of the gyro joints assembling is analyzed. Then a ayro joints assembly system is established based on the image analysis and force sensor control. Amodularize design idea is used to developed the assembling system. Some key technical modules including precision positioning, micro-vision and control system are studied respectively. A gyro joints assembling system is designed based on integrating all the modules. Finally, the feasibility and practicability of the system is tested by some experiments, and the repeatability can reach 5μm.
