Problems solved by technology

[0005] For the fault analysis of the tool magazine system, FMECA analysis is generally used at this stage, and the obtained risk priority number (RiskPriority Number, RPN) value has many defects of repeated numbers, and the disadvantages to other functions are not considered when taking reliability improvement measures impact, there are deficiencies in the analysis of system deterioration
How to avoid these problems and improve reliability, the existing research has not given a complete technical solution

Abstract

The invention relates to a method and device for improving the reliability of a tool magazine system. The method includes: step 1: using a fault analysis method to analyze potential faults of the tool magazine system to obtain key failure modes; step 2: based on the TRIZ analysis method, establishing A contradiction matrix, extracting a reliability improvement direction corresponding to the key failure mode in the contradiction matrix, and performing reliability improvement according to the direction.

Description

technical field [0001] The invention relates to a method and device for improving the reliability of a tool magazine system. Background technique [0002] With the increasingly fierce competition in the global market and the increasing demand of users for individualized product performance, the structure and function complexity of CNC machine tools is increasing day by day, and they are gradually developing towards high performance, high precision and high reliability. The accuracy, running speed and reliability of the automatic tool changer put forward higher requirements, so it is more and more important to study the reliability of the tool magazine system. [0003] The current research on reliability improvement is mostly based on the results of failure analysis to find out the key failure modes for improvement, mainly focusing on: According to the failure mechanism of the product, use the failure mode effects and criticality analysis (Failuremode Effects and Criticality ...
