Cutter working state monitoring device

Abstract

The invention provides a cutter working state monitoring device. The cutter working state monitoring device comprises a cutter clamp, a circuit board and a plurality of sensors, wherein a first clamping opening used for fixing a cutter is formed in one end of the cutter clamp, and a second clamping opening used for mounting the circuit board is formed in the other end of the cutter clamp; the circuit board is mounted in the second clamping opening of the cutter clamp and comprises a chip with built-in software, a sensor signal receiving device, a WIFI module and a power device; and the multiple sensors are all arranged on the cutter clamp and connected with the sensor signal receiving device of the circuit board, and comprise a receiving acoustic emission sensor, a vibration signal sensor, a cutting force signal sensor, a temperature sensor and a Hall sensor. By means of the device, the problems existing in traditional direct monitoring and indirect monitoring can be solved, and related state parameter information such as a cutting force signal, an acoustic emission signal, cutter rotating speed and temperature can be obtained in time.

Description

technical field [0001] The invention relates to the technical field of tool measurement, in particular to a tool working state monitoring device. Background technique [0002] In today's manufacturing industry, with the rapid development of technologies such as artificial intelligence and big data processing, analysis and mining, the health status monitoring of mechanical equipment has gradually developed from post-event fault diagnosis of processing equipment to early warning maintenance and life expectancy of processing equipment failure. forecast management. [0003] At present, the real-time working status of cutting tools of CNC machine tools also needs to realize intelligent early warning maintenance and life prediction management, mainly because the working status in cutting tool production plays a decisive role in the quality of workpieces. Once the tool is damaged, it may damage the workpiece and even cause machine tool accidents, thereby affecting product producti...

AI Technical Summary

Problems solved by technology

Although direct monitoring is highly operable and can obtain intuitive data, it is subject to environmental interference, resulting in data errors and insufficient accuracy

Although indirect monitoring can collect relatively accurate data, real-time monitoring is not enough, and the monitoring status information is not comprehensive
