ABSTRACT

Aiming at the demands of nuclear water chamber head’s multi-inclined holes and ramps in boring and milling, based on design requirements of special turning and milling machining center, B-axis structural design is put forward, research on deformation characteristics of ram components under different swing angle, propose the control methods of deformation and errors. Adopt modeling method of equal mass, construction of deformation and displacement analysis model of B-axis components, explore formation reason of maximum gap between components’ joint surface, form optimization design scheme of rotation structure of B-axis components. Trial-produce prototype of B-axis components, make experiment of trial cut water chamber head in turning and milling machining center, utilize test results of part's machining quality, verify unloading effects and machining accuracy of design scheme of B-axis components has been verified.
