摘　　要：展开轮作为钢球缺陷自动检测设备中实现全表面展开的关键零件,其工作表面对缺陷的检测精度起到了关键作用.为了研究其工作表面的轮廓度误差,首先通过预定位初始匹配与迭代精调整建立了展开轮的轮廓度误差评价匹配模型,可以实现模型的高精度匹配.然后通过数值计算对其工作表面进行轮廓度误差评定.采用上述方法以传统方法加工出的展开轮工作表面为实例进行轮廓度误差评定,结果表明其工作表面的轮廓度误差较大.Unfolding wheel as the key part of automatic detection device to expand the ball surface completely,its working surface is very important to detection accuracy of defect.In order to study the profile degree error of the working surface,firstly,the profile degree error evaluation matching model is established by the pre-positioning initial matching and iteration precision adjustment can achieve high-precision matching model.Then by evaluating the error of the surface profile degree of the working surface by numerical calculation.With the method above the working surface of unfolding wheel by processed with traditional method as an example of evaluating the profile error,the results show that the surface profile error is larger.This study has great significance to improve the machining precision of the parts.
