Adaptor for pneumatically operated pulling tool
Abstract
Abstract THE INVENTION RELATES TO AN ADAPTOR FOR CONVERTING A PNEUMATICALLY OPERATED PULLING TOOL (E.G., OF THE TYPE USED FOR PLACING BLIND BREAKSTEM RIVETS) INTO A TOOL WHICH CAN PLACE INTERNALLY THREADED ANCHOR SOCKET FASTENERS WHICH REQUIRE A THREADED PULLING MANDREL TO BE SCREWED INTO AND UNSCREWED OUT OF THE FASTENER. THE ADAPTOR COMPRISES A HIGH-SPEED REVERSIBLE AIR TURBINE MOUNTED DIRECTLY ON THE THREADED MANDREL SHAFT, VALVES CONTROLLING THE TURBINE, AND A SINGLE TRIGGER MECHANISM, WHICH AUTOMATICALLY ACTUATES BOTH THE TURBINE VALVES AND THE PULLING TRIGGER OF THE PULL GUN. WHEN THE ADAPTOR TRIGGER IS PRESSED AND RELEASED, THE FOLLOWING ACTIONS RECUR IN SEQUENCE: (1) THE MANDREL SCREWS INTO THE FASTENER, (2) THE MANDREL IS PULLED TO PLACE THE FASTENER, AND THEN RELEASED AGAIN, (3) THE MANDREL IS UNSCREWED FROM THE FASTENER.
