| Machine tool equipment is the most important basic equipment for machining enterprises.Dongfang motor mainly produces power generation equipment and supporting control devices.At present,the company has more than 300 large and small equipment,such as lathes,milling machines,boring machines,machining centers,etc.Among them,there are numerical control equipment and common equipment,and more than 40% devices are used for a long time.In order to make them play a greater role and improve the quality of the products and the economic benefit of the enterprises,it is very necessary to transform or renew the equipment.Especially after upgrading and transformation,the value of the transformation into CNC machine tools.This paper studies the numerical control technical transformation of the 225 floor boring and milling machine.The main research is as follows: 1.Formulating the general design and detailed design scheme of the numerical control transformation of the 225 floor boring and milling machine with SIEMENS 840 Dsl CNC system and corresponding configuration.2,how to reform the CNC system,server system and main drive system of the 225 floor boring and milling machine through the combination of the new system and the old machine tool.In order to solve the existing faults and meet the basic requirements and technical performance of the machine tools,3.The problems of some system parameters debugging and some functions realized in the process of reforming the machine tool are emphatically studied,such as the debugging of the simulated axis through the ADI4 module and the recovery of the vertical compensation function of the boring box.Restoring spindle shift function and restoring spindle orientation function.After the transformation,the performance of the NC machine tool has been greatly improved than before,a series of large and precision parts such as generator outlet hood and 4 military pump bodies have been completed.It not only improves the production efficiency,improves the processing precision,meets the quality requirements of the product processing,but also saves the company more cost and a large amount of time,provides reliable guarantee for the heavy production task,and makes numerical control transformation for the related machine tools after the company.A new world has been opened. |
