摘要：An installation for welding top plugs on to nuclear fuel rods comprising a devicefor axially holding the rod and setting it in rotation and a weld chamber, where the device

comprises a gripper and structure to close the gripper on the rod, where the structurecomprise a pusher to apply an axial force on to the gripper, a linear actuator of axisparallel to the lengthways axis of the device, a yoke translationally secured to thepusher, and able to rotate freely around a fixed axis orthogonal to the lengthways axiswhich is not secant with the latter, where the yoke is connected and able to pivot relativeto the linear actuator around a fixed axis parallel to the orthogonal axis such that thelinear actuator causes the yoke to rotate around the first orthogonal axis and causes thepusher to slide, closing the gripper on the rod.
