Abstract: 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 fourposition 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.
