Semi-Automatic Electromagnetic Riveting Bracket With Conical Structure

The limitations of conventional riveting methods were discussed, and electromagnetic riveting technology was proposed for the riveting of aerospace conical structures. The method of semi-automatic electromagnetic riveting system of aerospace conical structure assembly was developed to avoid the disadvantages of manual and automatic electromagnetic rivet-ing, and the details of the structure design and work-flow for the bracket of semi-automatic electromagnetic riveting system were also presented. The key technologies of the bracket include: automatic alignment of the rivet gun and top iron, the automatic angle adjustment of the workpiece, and the damping system design of the riveting gun. Finally, relevant problems which should be beyond controlled in manual riveting but solved by using semi-automatic electromagnetic riveting bracket are summarized.
