Problems solved by technology
Traditional data acquisition modules mainly use low-pass filters or anti-aliasing low-pass filters for the collected data, and all data need additional processing on the host computer
The delay in the data transmission process will cause problems in signal synchronization, which will bring difficulties to the deep noise reduction and fusion of signals.

The invention discloses an intelligent machine tool state monitoring device and a state monitoring method thereof, and relates to the technical field of operation monitoring of machine tool spindles. The device includes a current sensor for detecting the current signal of the machine tool spindle motor; a three-axis vibration sensor for detecting the vibration signal of the machine tool spindle; a data acquisition module, including a high-speed data input interface, an LCD screen, a communication interface and a power supply part, and the data acquisition module processes the signal and make status judgments. In view of the influence of strong electromagnetic and environmental interference of machine tools, the device can combine current signals to perform noise reduction processing on vibration signals, and perform real-time data fusion processing, feature extraction, fault diagnosis, status information display and fault detection on the data after noise reduction processing. Call the police. The present invention can quickly complete the state diagnosis of the machine tool through the real-time monitoring of the current and vibration related to the main shaft of the machine tool.
Description
technical field [0001] The invention relates to the technical field of operation monitoring of machine tool spindles, in particular to an intelligent machine tool state monitoring device and a state monitoring method thereof. Background technique [0002] With the development of technology, the requirements for product quality are getting higher and higher, and machine tools are also developing towards high speed and high precision. The wear and accidental failure of the machine tool will lead to the reduction of machining accuracy and downtime, which will eventually affect the machining efficiency and life of the machine tool. In order to ensure the machining accuracy and reliability of the machine tool, it is necessary to monitor the key components of the machine tool, and analyze the state of the machine tool based on the monitoring information. At present, there are many monitoring systems based on parameters such as machine tool temperature, vibration, and current, whi...
