薄壁圆环类零件的几何尺寸精度一般要求很高,采用三坐标触针测量存在一定难度,采用传统的万能工具显微镜测量难以保证精度,CCD镜头光学影像非接触测量可以较好地解决此类问题。通过对薄壁圆环类零件碟簧的内径、外径进行光学影像测量研究,取得了较好的效果。 Thin-walled annular parts of the geometric precision of the general requirements are high, the use of three-dimensional stylus measurement there is a certain degree of difficulty, the use of traditional universal microscope difficult to ensure the accuracy of the instrument, CCD lens optical image non-contact measurement can better solve these problems. Through the optical image measurement research on the inner diameter and the outer diameter of the thin-walled annular type disc spring, good results have been obtained.
