Design of Measurement and Control System for Performance Test Platform of Machine Tool Linear Feed System

  • 摘要: 为了研究机床直线进给系统的性能,设计了一种测试平台。其控制系统包括电机驱动、随动加载电机控制和气动控制,测量系统包括传感器布局和测量软件开发。设计了控制电路和控制器,以控制被测进给单元和随动加载单元的同步直线进给运动;采用气压缸模拟切削力,对被测进给单元在三个方向上施加随动力;合理布局温度、位移、加速度、扭矩、光栅传感器,以实现对被测进给单元各项性能参数的测试;开发了测量软件,用于采集传感器信号和分析被测进给单元的性能参数。应用设计的测控系统,测试并分析了切削力对直线进给系统温升和热误差的影响。结果表明:所设计的测试平台及其测控系统可以用于测试机床直线进给系统的各项性能。
