specific Embodiment
[0043] In this embodiment, the lathe turning and the monitoring of tool chatter are taken as an example. Using the method of the present invention to reconstruct the monitoring system includes the following steps:
[0044] 1) Install two acceleration sensors on the perpendicular surfaces of the cutting edge attachments of the turning tool, and then connect the sensors to the ICP acceleration sensor channel of the reconfigurable monitoring device.
[0045] 2) Start the reconfigurable monitoring platform of the upper computer, select the component management function, and then initialize the functional component library (the reconfigurable platform identifies the available functional components, and then displays each functional component and its function description information on the component management interface) .
[0046] 3) Select the vibration monitoring component, chatter analysis component, and data storage component on the component management interface, and then add ...

The invention discloses a machine tool functional component reconfigurable monitoring system and a machine tool functional component reconfigurable monitoring method thereof. The system is based on a machine tool functional component reconfigurable monitoring hardware device with a hardware frame of an embedded monitoring unit and a sensor signal conditioning module and a reconfigurable monitoring software platform with a software frame of a system engine and functional components. According to monitoring requirements of different functional components of a machine tool, sensors are selected and a corresponding signal conditioning module reconfigurable monitoring hardware device is replaced; and the functional components are dynamically loaded on the reconfigurable monitoring software platform, and corresponding functional component monitoring subprograms are downloaded to a modularized embedded monitoring device on line, so that the different functional components of the machine toolare monitored. The system and the method contribute to quickly constructing a monitoring diagnostic system for the different functional components of the machine tool; the reliability, safety and efficiency of machining of the machine tool are improved; and the application and the development of the monitoring diagnostic technique in the domestic machine tool industry are also promoted.
Description
technical field [0001] The invention belongs to the application field of mechanical equipment state monitoring systems, and relates to a monitoring system for machine tool functional components, in particular to a reconfigurable monitoring system for machine tool functional components based on the hardware architecture of "embedded signal acquisition monitoring unit + sensor signal conditioning module" and and its methods. Background technique [0002] Machine tools are the foundation of the entire manufacturing industry. The processing level of machine tools directly affects the quality and performance of other equipment, and also reflects the overall level of a country's industry. my country is a big manufacturing country, but not a strong manufacturing country. The main reason is that the overall level of machine tools in our country is low, and the processing quality cannot keep up. Therefore, improving the processing accuracy and level of machine tools has become the ke...
