摘要
An electrically-hydraulically powered rivet setting and crimping hand power tool is provided, having a battery driven electric motor mechanically powering an offset drive cam through a dual planetary drive gear, the drive cam being in direct mechanical contact with a dual volume, dual stage concentrically delivering longitudinally reciprocating piston pump being in direct hydraulic communication with a work engaging hydraulic cylinder surrounding a centrally fixed and stationary work piece puller shaft, wherein the work engaging hydraulic cylinder is thrust forward around the work piece puller shaft when the tool is activated thereby providing the mechanical motion to activate a user provided riveter nose assembly attachment. When activated by a trigger mechanism, the work engaging cylinder moves forward relative to the centrally fixed work piece puller shaft having a user provided riveter tool nose assembly attachment positioned such that a rivet fastener pin is pulled away from the rivet relative to the surrounding work engaging cylinder thereby fixing the rivet in place. The centrally fixed work piece puller shaft further comprises a hydraulically activated work piece extraction mechanism. A pressure relief trigger is further provided so as to retract the work engaging cylinder upon setting a rivet fastener. An alternate embodiment of the tool receives a user provided crimping nose assembly attachment may optionally be fitted wherein the work piece engaging cylinder motion relative to the centrally fixed work piece puller shaft is translated into a crimping action.
