摘要
根据直线电机驱动的高速立式加工中心的高速高精要求,总结现有直驱型立式加工中心的直线电机安装方法及工作台结构的不足,提出一种直线电机驱动的机床分体式工作台设计原理及方法。根据机床实际工作要求,对工作台组件进行极限切削载荷和加减速分析,建立分体式工作台结构的力学模型。利用SolidWorks Simulation有限元软件对分体式工作台进行静动态仿真分析,分析结果表明了分体式工作台设计的合理性。为直线电机驱动的机床工作台设计提供了一种新的思路和方法。
According to the requirements of high speed and high precision in the vertical machining center （VMC）driven by linear motor,a new installation method of linear motor and the principle of split worktable were put forward,considering the disadvantages which existed in the installation method of linear motor and the structure of worktable.According to the Actual working conditions,the split worktable＇s mechanics model was built by the analysis of the structure under the limit cutting load and acceleration.The SolidWorks Simulation was used in the structure＇s static and dynamic simulation analysis.The result shows that the new design is reasonable.The new idea of split worktable can be used for CNC machine tool driven by linear motor.
