Abstract: With the increasingly fierce competition in the automotive industry, the lightweight of vehicles has attracted more and more attention. Compared with bolts and other fasteners, rivets have the advantages of light weight, low cost and simple operation. Therefore, riveting technology has been widely used. However, because the dynamic process of riveting is not easy to identify, this paper introduces a rivet monitoring system to monitor the process of riveting to guarantee reliable connection. The system consists of code scanning equipment, pressure sensor, depth sensor, riveting gun, signal processing system, personal computer and operation software. The displace- ment and force sensors on the rivet gun obtain the real-time data in the riveting process. By comparing with the established data, the changes of parameters caused by the differences of target part thickness, rivet material and riveting aperture are found. The rivet monitoring system improves the ability of monitoring the riveting process and is of certain significance to the lightweight of vehicles.
