卡拉奇核电外缸关键部位加工研究

该项目两处加工困难的部位分别是上、下缸两端轴承座的异形槽和下缸的8个空间多角度深长孔。通过装夹方案研究及专用工装设计,空间多角度深长孔工件找平找正方案研究及大型异型槽加工方案及工装研究,实现该项目的加工。

The two difficult-to-machine parts of the project are the shaped slot of upper and lower cylinder bearing seat and 8 multi-angled long and deep holes of the lower cylinder. Through the study of fixture setup and special tooling design, the multi-angle long-holeworkpiece leveling and alignment scheme research and the large-scale special-shaped groove machining scheme and tooling research, theprocessing of the project is realized.
