一、概述 典型的仪器另件,如齿轮、精密丝杆等,多年来,已有繁如烟海的文献对它们详加研究。但对于最终安装这些另件并对最终精度有着极其严重影响的箱体,其测量方法的研究却较为少见。尤其在仪器结构中,由于仪器箱体一般外形较小,孔系尺寸精度要求(?),箱壁很 First, an overview of the other typical pieces of equipment, such as gears, precision screw, etc., over the years, there are numerous literature on them exhaustive study. However, the research on the measuring method of the box which finally installs these pieces and has extremely serious influence on the final precision is rare. Especially in the instrument structure, due to the general shape of the instrument box is small, hole size accuracy requirements (?), The wall is very
