摘　　要：在对某系列特种弹药的药筒结构尺寸分析和归类的基础上,针对目前筒形零件壁厚测量上存在的测量精度低、自动化程度低等问题,提出了一种高效率、高精度自动检测的方法,详细阐述了药筒壁厚尺寸的测量原理,并结合工厂实际,采用差动式位移传感器和计算机技术,实现了药筒壁厚尺寸的数字化测量与评价。实际应用表明该系统可有效提高药筒壁厚尺寸的测量精度并定量评价药筒的尺寸误差,壁厚的测量精度可达20μm以内,能有效指导加工的工艺流程和加工的尺寸精度控制。Based on a kind of special ammunition cartridge structure size analysis and classification,measurement accuracy for the measurement of wall thickness of the cylindrical part is low,the low degree of automation,a high- efficiency,high- precision automatic detection method,elaborated on the cartridge wall thickness measurement principle,combined with the actual plant,the use of the differential displacement sensors and computer technology,digital measurement and evaluation of the wall thickness of the cartridge. Practical application shows that the system can effectively improve the measurement accuracy of the thickness dimension of the cartridge and the quantitative evaluation of the dimensional error of the cartridge,the wall thickness measurement accuracy up to 20μm or less,can effectively guide the processing process and the precision control of the machining dimension.
