Power-driven or manually-operated wrench puller for tightening or loosening threadedly-engaged work pieces

摘要

A connector torquing system useful for tightening or loosening a pair of interthreaded components is shown. A torque receiving means is spaced about each of the interthreaded components concerned. A gimbal is disposed at the opposite extremity of each torque receiving means and includes inner and outer pivot blocks swingable with respect to each other in mutually perpendicular axes. Each torque receiving means is connected to its respective gimbal. A screw is extendable between and through each gimbal. A pair of nuts are threadedly engaged on the screw outboard of an adjacent one of the gimbals and the nuts of the pair are tightened. A single nut is threadedly engaged on the screw within an adjacent one of the gimbals and aids in the rotation of the screw responsive to the tigthening of the nuts of the pair. In this way concomitant angular deviation of the inner and outer pivot blocks of the gimbals achieves the displacement of the torque receiving means as they are driven toward each other.
