Acquisition system of maintenance reliability data of numerically controlled machine tool and method

Abstract

The invention discloses an acquisition system of maintenance reliability data of a numerically controlled machine tool and a method. The system comprises multiple portable mobile terminals used for acquiring maintenance reliability data of the machine tool, and a data center used for receiving and analyzing the data. Each mobile terminal comprises an input module used for acquiring data recording, a local storage module used for storing the data, a display screen used for human-machine interaction and a wireless communication module used for carrying out network communication. The invention also discloses a method for carrying out maintenance reliability data acquisition by use of the system. According to the invention, the system and the method are advantageous in that accuracy of data acquisition can be improved; data structures are quite standard; counting and analysis of the data are facilitated; improvement of accuracy of reliability data analysis is facilitated; the system and the method can help a maintenance worker to carry out fault diagnosis; diagnosis accuracy is improved; and prolonging of service lifetime and improvement of reliability of the machine tool are facilitated.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tool maintenance data acquisition, in particular to a numerical control machine tool maintenance reliability data acquisition system and method. Background technique [0002] With the continuous advancement of science and technology, the development of CNC machine tools presents a trend of high speed, high efficiency, automation, high precision and high reliability. Compared with the world's advanced level, domestic CNC machine tools have unstable performance, short precision life cycle and poor reliability during operation. Among them, reliability is the key factor restricting the development of my country's machine tool enterprises, and the basic premise to improve the reliability of domestic CNC machine tools is Accurate collection of reliability data, especially the collection of maintenance reliability data. [0003] Currently, machine tool companies collect maintenance reli...

Problems solved by technology

This method of inputting maintenance reliability data has the following disadvantages: arranging special personnel to input data will undoubtedly increase the cost of data collection and cause waste of resources; The larger the value, the lower the accuracy of the collected reliability data

In addition, due to the uneven technical level of maintenance personnel, the judgment of the cause of the failure and the selection of solutions will directly affect the service life and reliability of the machine tool. At the same time, most of the existing reliability data are entered in text, which is relatively random , the data structure is poor, and the expression of the same fault lacks uniqueness
