Abstract: A nose assembly for a fastener installation tool including an anvil, a collet, and a drawbar having a primary bearing. A secondary bearing is positioned within the collet and located intermediate the primary bearing and jaws of the collet. The secondary bearing is offset from the fastener centerline by a first distance and from a pulling tool centerline axis defined by a longitudinal axis of the drawbar by a second distance. In a pull position, the primary bearing remains engaged with the anvil during a loaded stroke and limits anvil deflection relative to the fastener centerline, while the secondary bearing remains engaged with the collet during the loaded stroke and limits deflection of the collet relative to the fastener centerline. In a return position, the primary bearing remains engaged with the anvil during a return stroke, while the secondary bearing remains engaged with the collet during the return stroke.

Abstract: The present invention relates to an oblique-driven platform having three coplanar driving axes, in which three oblique driving modules are disposed on an identical base, so as to drive a work platform to rotate and carry out 2-dimensional motion by the controlling of the three oblique driving modules. Thus, this design could solve the problems occurring in the conventional stacked machine tools; such as the deformation or the displacement of the sever axis or the rotation axis caused by the upper-layer machine tools. Moreover, by the disposing of the three oblique driving modules, the work platform can be driven to stably rotate and carry out 2-dimensional motion with high precision and high accuracy.
