Study of distributed multiaxial intelligent tightening machine based on fieldbus control system

We put forward a system structure of controlling the tightening operation of bolts using multiraxial tightening machine. A kind of fieldbus intelligent tightening control system is designed with the technology developing of fieldbus intelligent instrumentation. This system is a distributed structure based on fieldbus control system which consists of CAN bus, Profibus-DP bus, and adopts many advanced intelligent control methods. This system structure and intelligent control method study realizes integration of manufacture, control and management in the tightening of bolts and improves the level of network manufacture and information management of automobile industry. The integrating of tightening machine and fieldbus brings a new thought of automobile industry control technology.
