摘要
对于已经建立的数控镗床转台模型,首先进行结构分析,通过对电机驱动的回转轴系和手动调整结构的分析和计算,得出了转台的回转精度小于0.5",结果表明转台的回转精度满足设计指标要求。然后利用ANSYS Workbench软件对转台进行静力学分析。为了减少工作量,将静力学分析的对象由转台整体转变为转台3个主要部件,即工作台面、外套和调整壳体,最后得到3个部件的应力和变形情况,得出了转台最大的变形要小于1.35μm。结果表明,转台的结构设计符合设计的要求,同时也对转台结构的优化提供依据。
For built CNC boiling machine turntable,structure is analyzed firstly.By analyzing and calculating of motor-driven rotary shaft and manual adjustment structure,rotary accuracy is less than 0.5" arc-second.This indicates the rotary accuracy meet the design demand.Then the turntable is analyzed its static characteristic in ANSYS Workbench.To reduce work,the target of static analysis is changed whole turntable to three main parts,and strain,stress and deformation are got.The maximum deformation is less than 1.35 ujn.The result indicates the design of turntable meets the design demand,and provides the basis for the optimization of the structure of the turntable.
