运载器排焰口的自动铣切工艺研究
Research on the Automatic Milling Technology of Rocket Flame Outlet

针对传统手工制运载器排焰口精度差、效率低、工人劳动强度大等问题，借用自动钻铆设备，提出自动铣削窗口的方式，突破了基于线激光校准的桁条高精度定位技术、粗铣留余量–精铣角度补偿法技术和基于程序嵌套的快速编程技术，实现了排焰口的自动铣切，并与手工铣切进行了对比，自动铣切效率高、精度高、质量一致性好。
In order to solve the problem of poor accuracy, low efficiency and high labor intensity of rocket flame outlet using traditional manual milling, the automatic milling is proposed by using the automatic riveting equipment. It breaks through the key technology of high precision positioning of stringer using line laser calibration, leaving a margin when rough milling and angle compensation when precision milling, fast programming technique based on program nesting, and realizes the automatic milling of flame outlet hatch. Compared with manual milling, automatic milling has high efficiency, high precision and good quality consistency.
