摘　　要：针对当前电动刀架无法有效进行加工过程刀具状态感知和监控等问题,对电动刀架的机械结构及监控系统进行了研究,提出了一种新型四工位电动刀架机械结构。设计了基于霍尔传感器、温度传感器、加速度传感器、PLC及触摸屏的新型电动刀架监控系统,实现了刀架内旋转部件中传感器的持续供电与数据监控;对新型电动刀架及其监控系统进行了点动换刀、自动换刀、刀具温度及振动实时监测等功能的测试。研究结果表明:新型四工位电动刀架换刀速度优于900 ms/工位,可有效监测刀具工作状态,使得机床切削加工过程更加智能。Aiming at the problem that the current electric tool holder cannot effectively perceive and monitor the tool state in the process of machining,the mechanical structure and monitoring system of the electric tool holder were studied.A new mechanical structure of the fourposition electric tool holder was proposed.A new type of electric tool holder monitoring system based on Hall sensor,temperature sensor,acceleration sensor,PLC and touch screen was designed,which realizes the continuous power supply and data monitoring of the sensor in the rotating parts of the tool holder.The new electric tool holder and its monitoring system were tested for the functions of point change,automatic tool change,real-time monitoring of tool temperature and vibration.The results indicate that the speed of tool change of the new four-position electric tool holder is better than 900ms/station,which can effectively monitor the working state of the tool,and make the cutting process of the machine tool more intelligent.
