摘　　要：为了实现对钢球表面缺陷快速高效的全自动在线检测,在分析钢球展开机构基本工作原理的基础上,对钢球展开机构进行了设计与分析,建立钢球表面展开数学模型,确定展开轮、驱动轮、支撑轮等核心部件的相对位置关系和重要参数,并从碰撞力的角度对设计的展开机构进行仿真分析和实验验证。结果表明,所设计的展开机构能够实现钢球表面的完全展开,并可对钢球进行快速检测,为钢球检测装置样机的制造提供可靠的理论依据。In order to achieve fast and efficient of the steel ball surface defects of automatic on-line detection,On the basis of analyzing the basic working principle of the steel ball unfolding mechanism,the Unfolding mechanism are analyzed and designed,established the mathematical model of steel ball surface,to determine the relative and the important parameters between the expansion wheel,driving wheel and supporting wheels. The simulation analysis and experimental verification of the unfolding mechanism are carried out from the point of view of collision force. The results show that the unfolding mechanism to achieve the fully expanded on the surface of the steel ball and completed the rapid detection of steel ball,it provides a reliable basis for the prototype manufacture of steel ball detection device.
