Research Of Automatic Production Line Technology For Automotive Hub Unit

China's automobile industry continues rapid growth,but in the domestic car key parts and components manufacturing industry,represented by wheel hub unit,the key equipment of the manufacture of car key parts is controlled by foreign supplier such as Landis,DMG,Adcole and so on,home-made numerical control machine tools,robots has little chance of sale.Also,key technologies are blocked,and the device is less open,which makes it difficult to realize intelligent manufacturing.In the context,the establishment of production line control system for automotive hub unit composed of domestic equipment is of great significance in improving the level of domestic equipment technology and promoting the manufacture level of intelligent car wheel hub unit.In this paper,Base on the car wheel hub unit automatic production line,the Production line control system based on Redis master-slave servers is designed,which realizes equipment condition monitoring,data management,user management and the analysis of historical data.The main research is as follows:Firstly,this paper designs the processing procedure of automobile wheel unit,as well as location of key working procedure,and the production tempo Requirements is analyzed from the perspective of target yield.A model to study the relationship between production line equipment layout and Production takt is built,according to which the layout of the whole automatic production line is planned.Secondly,feeding mechanism and blanking mechanism are designed,and according to the Processing craft and production line layout of automotive hub unit,the model selection of NC machine tool and robot is done.The topology structure of workshop network is designed,and the innovative introduction of Redis master-slave technology is applied to the construction of the server in workshop,which helps the topology structure design of Redis master-slave servers,and the model selection is done based on theoretical calculation.Finally,the requirements of production line control system are analyzed in detail from the perspective of function and performance,and the production line control system based on the high performance Redis memory database is designed.The control system separates the data collection layer and the real-time application layer,blocks the difference of the underlying equipment,improves the flexibility of production line,makes it easier to adjust and expand the production line;Production line equipment state monitoring,basic data management,user management,historical data analysis and other functions are integrated to realize workshop production visualization management.Base on above analysis,this paper constructed a virtualization platform for simulation experiments,and tested the function of the designed production line control system and Redis master-slave servers,the test results showed that both of them met the design requirements.
