Abstract
A blind fastener installation tool comprises a structural housing which features a mechanism for securing a fastener installation assembly in position relative to the structural housing during the blind installation of a fastener; and a mechanism for reciprocating the fastener installation assembly relative to the structural housing at the conclusion of blind installation. The blind fastener installation tool also comprises a fastener installation assembly. This assembly comprises (1) a pull rod assembly comprising a mechanism for pulling a first portion of a fastener; (2) an annular, piston-actuated, piston-decoupled pull rod actuation assembly to translate the pull rod assembly; and (3) a nose assembly comprising a fastener receptacle for securing the position of a fastener; and one or more optional pull rod translation dampening assemblies to smoothly and effectually dampen the sudden translation of said pull rod assembly after pintail break.
