本文介绍了一种经济型柱面自动打磨车床控制系统的设计方案。本方案由压力传感器采集打磨头与柱面间压力,由压力控制打磨精度和质量;PLC内部集成位置控制功能,通过三台步进电机驱动打磨电机空间移动;有42个功能键的文本显示器构成人机界面。PLC的两轴位置控制功能通过外部继电器切换控制三台步进电机,运行可靠,降低了系统硬件成本。 This article introduced a kind of economy cylindrical automatic polishing lathe control system design plan. This program by the pressure sensor to collect the pressure between the grinding head and the cylinder, the pressure control grinding accuracy and quality; PLC integrated position control function, through the three stepper motor driven grinding motor space movement; 42 function keys text display constitutes HMI. The PLC’s two-axis position control function controls the three stepper motors by external relays to operate reliably and reduce the system hardware cost.
