To solve the problems of lacking consistency and heavy workload in aircraft manual electromagnetic riveting, the semi-automatic electromagnetic riveting system with bracket was designed, which was composed by control unit,assembling frame unit, clip bracket unit, door frame unit, riveting unit and supporting unit. Control unit was used to control the whole system motion and riveting; assembling frame was used to provide rigidity foundation for workpiece and other structure units.The clip bracket unit and the door frame unit function were combined to ensure riveting and supporting unit move synchronously to realize the single operation of electromagnetic riveting; the clip bracket unit used the balance cylinder to overcome the gravity of riveting unit and the supporting unit.In view of the problem of large feedback force, the buffer and supporting cylinder double vibration reduction structure were designed to reduce the influence of feedback force on the operator; because different rivets diameter needed different riveting force, the supporting air cylinder airpressure could be adjusted to adapt to different feedback force. To guide the movement way in X,Y and Z directions, linear rails were assembled in the bracket coordinate system, and the riveting consistency could be kept. A workpiece riveting experiment of 5 mm aluminum rivets was done based on the work process of electromagnetic riveting bracket.The results show that by using this system, the semi-automatic riveting of small-curvature panel structures can be completed.
