真空吸具在球壳电子束焊接中的应用

Application of vacuum attracting instrument in welding spherical shells by electron beam

分析球壳电子束焊接装夹的特点,运用真空吸具的优点,设计出一种快速、精确可靠的真空吸具辅助装夹系统,解决了长期以来球壳电子束焊接装夹找正难的问题。

A rapid, precise and reliable vacuum attracting instrument which could be used as a assistant assembleing and fixing system was schemed out, by analyzing assembleing and fixing characteristics of welding of spherical shells by electron beam, and exerting merit of vacuum attracting instrument. This vacuum attracting instrument resolved the long-term problem of correct locating during welding spherical shells by electron beam.
