| Abstract: | It describes the structural characteristics and tools changing process of a type of domestic horizontal machining center. Based on analyzing its failure date, it sets up the reliability model of tools changing system, analyzes its reliability features. The model shows that the reliability weak links are mechanical arm devices and magazine devices. It presents a detailed analysis of usual failures from mechanical arm failures, magazine failures, hydraulic failures and electric control failures. The results c... |
