摘　　要：针对主动式、磁控型和磁流变型气囊抛光工具的不同结构特点和使用功能的有效集成问题,基于模块化理论,将产品需求多变性和主体结构标准化有效结合起来,充分利用共用性和组合优化效应,完成了模块化气囊抛光工具的设计,并为产品族规划打下了基础;开展了模块化基础理论、功能模块划分、结构细化设计和产品族规划等方面的分析与研究,通过柔性工作模块、磁场发生器模块、气控容腔模块、动力模块、连接板模块和传感测控模块等,充分保证了新型气囊抛光技术自动、柔性、可控、多变的特点;在以模块化气囊抛光工具为核心的机器人辅助模具自由曲面抛光平台上,进行了相关的试验研究。研究结果表明:将模块化气囊抛光工具应用于模具钢抛光,能获得Ra0.006μm的高质量表面。Aiming at the problem of effective integration of active, magnetic control and magnetorheological gasbag polishing tool with different structural features and use functions, its modular design was completed based on modular theory, considering the demand variability of product and standardization of main structure, and utilizing the sharing effect and combinatorial optimization, which is also the basis of product family programming. The basic modular theory, a functional module partition, detailed structural design and product family programming were analyzed. Through the modules of flexible working, magnetic field generator, pressure control cavity, motivation, connecting piece, measurement and control, automatic, flexible, controllable, and changeable characteristics of novel gasbag polishing technique were guaranteed. The polishing experiments were carried out on the robot-assisted polishing platform on free-form surface mould. The core of which is the modular polishing tool. The results indicate that modular polishing tool applied to polish die steel can obtain high-quality surface Ra 0.006 μm.
