Embedded spindle system abnormal state intelligent detection and information push device

Abstract

The invention provides an intelligent detecting and information pushing device for an embedded spindle system abnormal state. The device comprises a vibration sensor, a temperature sensor, a numericalcontrol system, a data acquisition system, a data storage system, an embedded controller, a data processing system and an information pushing system. According to the device, the vibration sensor andthe temperature sensor are installed on a front bearing and a rear bearing of a motorized spindle shaft respectively, and sensor signals are collected through the data acquisition system, a spindle current signal collected in a machine tool is combined, and control and calculation are carried out generally by the embedded controller; the data can also be stored, and finally the calculated resultis pushed to external equipment to be checked by technicians. According to the device, real-time early warning can be carried out on the abnormal state of the spindle, and the equipment maintenance personnel can be notified in time, so that the fault shutdown time is shortened.

Description

technical field [0001] The invention relates to the field of machine tool fault diagnosis, in particular to an embedded spindle system abnormal state detection and information real-time push device. Background technique [0002] The state detection system of the existing machine tool spindle system usually only relies on external sensors or internal relays of the machine tool to collect signals and uses the host computer to further process the signals. [0003] After searching found: [0004] The Chinese invention patent with the notification number CN102825504A discloses a "method for detecting the state of the spindle of a CNC machine tool", which uses a temperature sensor, an acceleration sensor and a displacement sensor and processes the signals collected by these three sensors to determine the state of the spindle. However, this method only uses external sensors, which are not comprehensive enough as a signal for judging the state of the spindle, and the upper computer...

AI Technical Summary

Problems solved by technology

This method only uses the internal signal of the machine tool, which is not comprehensive enough as a signal for judging the state of the spindle, and the embedded information processing component is separated from the upper computer, which increases the equipment
