Intelligent tool magazine system suitable for numerical control machine tool and control method of intelligent tool magazine

Abstract

The invention provides an intelligent tool magazine system suitable for a numerical control machine tool. The intelligent tool magazine system comprises a tool encoding detection unit, a tool magazinemachinery unit, a tool magazine master control unit, an auxiliary tool changing unit and a manipulator unit. The invention also provides a control method of the intelligent tool magazine suitable forthe numerical control machine. The control method comprises the following steps: providing the intelligent tool magazine system, performing code initialization on the intelligent tool magazine system, and re-building a real-time encoding database; and searching for empty tool spacings, tools with insufficient service life and damaged tools in the intelligent tool magazine system by retrieving a database with a retrieval command, performing tool selection control, and examining the tools at an NC end and programs after tool changing. The control method has the following advantages: initialization of tool magazines with repeated tool numbers and searching of the empty tool spacings, tools with insufficient service life and damaged tools can be realized, and the standby tools can be automatically changed in real time during machining. Meanwhile, classification of process tools and process studies on the tools can be achieved. A one-step one-tool-number process is realized.

Description

technical field [0001] The invention relates to the technical field of tool magazines in numerically controlled machine tools, in particular to an intelligent tool magazine system suitable for numerically controlled machine tools and a control method thereof. Background technique [0002] As mass production becomes more and more concentrated, labor costs are getting higher and profits are getting lower and lower, improving the level of automation is the only way to improve production efficiency and reduce production costs. In the field of CNC machine tools, the tool change, tool selection, tool damage inspection and error correction of the tool magazine are now relying on manual work and different departments, which greatly wastes processing time. In addition, the tool change method is also fixed tool selection and random tool selection. Its realization is basically based on the tool holder number and random tool number of the existing tool library and the tool library syste...

Problems solved by technology

[0003] With the development of numerical control technology and FMS manufacturing, unmanned production in the workshop is a major trend; however, when the tool life prediction, tool replacement and replacement process are realized, manual modification of its data and debugging is required, and the efficiency is very low; and now The failure rate of the tool magazine system and the tool management system have been unable to meet the needs of FMS
