大尺寸螺纹检测技术研究

Research on Measurement Technique to Thread of the Large Size

针对型号产品中大尺寸螺纹检测的难题,以激光三角法为理论基础,开展了螺纹参数的激光三角法应用方法、数据处理算法等研究,突破了螺纹牙型完整轮廓的检测技术,构建了螺纹检测校准装置,实现了非接触检测螺纹参数目的,可满足型号产品使用的大尺寸螺纹检测需求。

According to the difficulty of measurement thread of the large size, researchers carried out researches, such as the application of the laser triangulation method on thread parameters, data-pro- cessing algorithm and so on, made a breakthrough in testing the complete contour of thread form, built a device with thread testing and calibrating so that achieving contactless testing for thread and meeting the demands of the large size of thread testing.
