基于主轴电流信号的防碰撞功能的研究

Research of the Anti-collision Function Based on the Spindle Current Signal

随着智能控制技术的发展,对设备的安全性提出了更高的要求,针对磨床在磨削过程中砂轮容易与其它零部件或工件发生碰撞,提出了在不改变机床任何结构的情况下通过加装防碰撞智能控制系统,利用电流、功率传感器在线监测磨床主轴电流信号的变化,通过智能控制器IMC负责分析和处理接收的信号,分析出电流信号与磨削力的相关性,间接的控制机床的进给运动,这样既可以避免磨削加工过程中发生异常碰撞,也为企业节约一定的设备改造费用,同时也提高了产品的生产效率和设备使用的安全性。

With the development of intelligent control technology, higher requirements are placed on the safety of the equipment. In view of the easy collision of grinding wheel with other parts or workpieces during grinding, it is proposed that the current and power sensors can be used to monitor the change of spindle current signal without changing any structure of machine tool. It also saves the cost of equipment modification for enterprises, and also improves the production efficiency and safety of equipment use.
