个性化轮椅自动装配系统的开发

Development of automated assembly system for individualized wheelchair

以Pro/Engeneer为开发平台,通过MFC和PRO/TOOLKIT开发工具相结合的方法,基于坐标系重合原理,在轮椅车体和个性化附件之间进行自动装配。结果表明基于坐标系重合的自动装配方法与现有的装配方法相比更加方便、实用,而不需要查找零件的几何特征和设立零件几何特征之间的约束关系。将这种二次开发的自动装配方法及友好的用户界面应用于个性化轮椅系统中,完全能够实现参数化装配设计,满足不同轮椅用户的需求。此技术在其它领域具有一定的通用性,为其它自动装配系统的开发提供很好的借鉴作用。

In the system,automatic assembly in view of coincidence principle of coordinate system between the wheelchair＇s body and individuated accessory is accomplished through PRO/TOOLKIT and MFC based on the Pro/Engeneer platform.It turns out to be that the automatic assembly based on Coordinate system coincides is more convenient and practical than other approach of assembly which need to find constraint relations between the geometric features and the creation of part geometry.Automatic assembly Technology of Secondary Development and friendly user interface are used in the individualized wheelchair system,in which parametric design is achieved and different requirements of wheelchair users is satisfied.With the commonalities of the technology in other areas,it will provide a good reference in developing other automated assembly systems.
