微加工中心自动换刀控制系统设计 摘要：自动换刀系统是一种带有刀库和自动换刀装置的机电一体化产品，它的发展和应 用能够减少换刀过程中浪费的时间，使工业生产的效率和质量大大提高。本文即对自动 换刀系统控制技术进行了研究，设计了一个基于 PLC 的微加工中心自动换刀系统。硬 件部分使用 PLC 做控制器来控制 1PG 输出控制脉冲，并通过步进电机驱动器驱动刀库 旋转进行换刀；主轴的前进后退使用 PLC 直接控制，刀库的前进后退以及主轴的松刀 夹刀使用液压泵等液压元件来控制。软件部分使用 GX Developer 进行编程、MCGS 组 态软件进行模拟监控，最终证明系统可行。 关键词：加工中心；刀库；自动换刀装置；PLC ；MCGS I Design of automatic tool changing control system for micro-machining center Abstract: Automatic tool changing system is a mechatronic product with tool library and automatic tool changing device. Its development and application can reduce the time wasted in tool changing process and greatly improve the efficiency and quality of industrial production. In this paper, the control technology of automatic tool change system is studied, and an automatic tool change system of micro-machining center based on PLC is designed. In the hardware part, PLC is used as the controller to control 1PG output control pulse, and stepper motor driver drives the tool library to rotate to change the tool. The forward and backward of the spindle are controlled directly by PLC. The forward and backward of the tool storehouse and the loosening knife clamp of the spindle are controlled by hydraulic components such as hydraulic pumps. In the software part, GX Developer is used to program and MCGS configuration software is used to simulate and monitor, which finally proves that the system is feasible.
