Apparatus and method for synchronized multi-stage electromagnetic rivet guns

摘要

A method and system for installing rivets is disclosed. The method involves positioning a rivet through a structure to be joined. The method further involves positioning a first rivet gun on a first side of the rivet and positioning a second rivet gun on a second side of the rivet. The method also involves synchronizing firing of the first and second rivet guns, so as to cancel forces that otherwise would propagate into the structure during installation of the rivet.

1. A method for installing rivets, the method comprising:
positioning a rivet through a structure to be joined; positioning a first rivet gun on a first side of the rivet; positioning a second rivet gun on a second side of the rivet; and synchronizing firing of the first and second rivet guns, wherein synchronizing firing of the first and second rivet guns comprises timing opposing impacts of the first and second rivet guns based on (i) a force at which the opposing impacts occur, (ii) structural properties of the rivet, and (iii) a speed of impact waves created by the opposing impacts, so that each opposing impact at a given side of the rivet occurs at substantially the same time as an impact wave caused by another opposing impact at the other side of the rivet reaches the given side of the rivet.
