Abstract: At present,in the process of automobile manufacturing,there are a large number of methods to use bolt fastening as part connection,which involves a lot of parts that need key quality control,and the operation quality assurance of these parts is particularly important. If poor quality is discovered through on-site operation in the market,it will cause irreversible losses to users and vehicle enterprises. Therefore,starting from the research on torque anomaly management methods for automobile assembly and inspection,based on the overall perspective of the factory,this paper elaborates on the management mode,process document system,and pokayoke technology for controlling torque anomalies,and creates an anomaly handling management system for automobile manufacturing enterprises.

Key words: abnormal handing, torque, self process quality completion, pokayoke
