数控龙门移动式双柱立式车铣床基座分析与计算

摘要

对数控龙门移动式双柱立式车铣床基座床身大件进行有限元分析,并对基座滑板静压蜗母条比压进行计算.分析和计算结果验证了该台机床基座部分结构设计的合理性,保证了龙门架移动的可靠性及机床的稳定性.%Finite element analysis was done for vertical turning and milling lathes with two columns and a traveling bridge, as well as calculation for pressure ratio of hydrostatic worm rack of base saddle. Analysis and calculation results indicate the design ration ality of the base structure, and die stability of the machine tool and the reliability of traveling bridge are insured.
