摘　　要：针对发动机缸盖气门座圈密封带锥角及深度关键尺寸检测难度大的问题,提出一种双球检测法。基于球体与圆锥体的特殊配合关系构建气门座圈密封带关键尺寸测量的数学模型,通过测量常规尺寸即可推算出气门座圈关键尺寸。该检测方法稳定可靠且效率高,可作为缸盖批量生产的有效在线监测手段。In response to the difficulty in detecting the key dimensions of cone angle and depth of the valve seat sealing belt in engine cylinder heads,a dual ball detection method is proposed.Based on the special fit relationship between the sphere and cone,a mathematical model for measuring the key dimensions of valve seat sealing belt is constructed.By measuring the conventional dimensions,the key dimensions of the valve seat can be calculated.This detection method is stable,reliable and efficient,and can be used as an effective online monitoring method for mass production of cylinder heads.
