Large-scale numerical control machine tool fault monitoring system based on multi-sensor

Abstract

The invention discloses a large-scale numerical control machine tool fault monitoring system based on multi-sensor. The large-scale numerical control machine tool fault monitoring system based on themulti-sensor comprises a sensor module, a data acquisition module, a summary module, a data analysis module, an information monitoring module, a controller, a data interconnection module, a storage module, a data processing module, an emergency stop button, an alarm, a data calculation module and a warning light; after obtaining Ti and Yi, the data analysis module in the invention transmits the Tiand Yi to the information monitoring module; the information monitoring module compares Ti and Yi with preset values t and y separately, generates an overhauling signal and a replacement signal, andtransmits the overhauling signal and the replacement signal to the data interconnection module through the controller; and the data interconnection module displays the received overhauling signal andreplacement signal on the mobile phone of the staff, which is convenient for the staff to understand the wear condition of the tool over a period of time, and to overhaul and replace the tool with a large degree of wear.

Description

technical field [0001] The invention relates to the technical field of fault monitoring systems, in particular to a multi-sensor based fault monitoring system for large numerically controlled machine tools. Background technique [0002] CNC machine tool is the abbreviation of numerical control machine tool, which is an automatic machine tool equipped with a program control system. CNC machine tools can process programs with control codes or other symbolic instructions, and decode them, express them in coded numbers, and then input them into the CNC device through the information carrier. After calculation and processing, the CNC device sends out various control signals to control The movement of the machine tool, and automatically process the parts according to the shape and size required by the drawing. In addition, a large number of sensors and travel switches are installed in the CNC machine tool, and combined with a fault monitoring system to monitor the safe and accura...

Problems solved by technology

[0003] However, in the existing CNC machine tool fault monitoring system, it is difficult to monitor and analyze the wear of the tool within a period of time, and it is easy to affect the processing effect and service life of the tool; and it is impossible to perform real-time monitoring of the spindle speed. Monitor and calculate, and make corresponding reminders in time, which will easily affect the machining accuracy of CNC machine tools; at the same time, it is difficult to judge the tool change of CNC machine tools in real time to improve the motion accuracy of the tool disc
