Intelligent milling cutter system based on RFID (Radio Frequency Identification) technology

Abstract

The invention discloses an intelligent milling cutter system based on a RFID (Radio Frequency Identification) technology. The intelligent milling cutter system comprises a main shaft mounted on a base of a machine tool; a cutter handle is mounted on the main shaft; a cutter is mounted on the cutter handle; a primary unit is fixedly mounted on the base; a secondary unit is fixedly mounted on the cutter handle; a sensing unit is fixedly mounted on the cutter, is mounted in a position close to a cutting edge of the cutter and is connected with the secondary unit through a conducting wire; the sensing unit is used for sensing the physical quantity of the cutter in the cutting process; the secondary unit is used for on-line sampling of the physical quantity sensed by the sensing unit and transmitting the physical quantity to the primary unit through a wireless transmission channel; the primary unit is used for generating a radio-frequency carrier wave and obtaining data transmitted by the primary unit in the wireless transmission channel. The intelligent milling cutter system completes the simultaneous transmission of energy and data through the same transmission channel, is simpler in structure, more in sensed physical quantity and high in transmission speed, can be used for identity recognition of the cutter and is compatible with an intelligent cutter management system.

Description

technical field [0001] The invention belongs to the field of intelligent cutting tools, and more specifically relates to an intelligent milling cutting tool system based on RFID technology. Background technique [0002] In the processing process, in order to better ensure the quality of the processed parts, it is necessary to monitor various physical quantities in the processing process online in real time; more and more intelligent tools are developed for the characteristics of milling processing; the existing intelligent milling tools It mainly uses Bluetooth plus lithium battery, surface acoustic wave and other technologies, or uses different transmission channels to realize the transmission of detection data and energy. [0003] However, further research shows that there are many deficiencies in the existing milling intelligent tool system. First, the way of wireless transmission module and battery will make the energy not be replenished in time, so that the intelligent ...
