Abstract
A portable torque power tool is disclosed herein and includes: a motor to generate a turning force; a drive to transfer the turning force; a turning force multiplication mechanism assembly to multiply the turning force; a shifter assembly to shift the tool between a lower speed/higher torque (LSHT) mode and a higher speed/lower torque (HSLT) mode; a torque transducer to measure torque output; wherein torque output is controlled by the torque transducer in LSHT mode; and wherein torque output is controlled by motor current in HSLT mode. In one embodiment of the present application, the torque transducer is a wireless torque transducer assembly formed at or near an output of a housing of the turning force multiplication assembly to improve measurement accuracy of torque output. Advantageously, simplified tool and system design and operation; reduced tool and system size; expanded functionality, greater durability and intuitive usability; and increased tool and system portability, efficiency, reliability and repeatability, all at low cost, are achieved. Further disclosed herein is an operation parameter regulation unit for use with a bolting system having a plurality of networked electrically powered torque tools and/or drive portions of torque tools described above for simultaneous tightening of industrial threaded fasteners. The operation parameter regulation unit includes: a processing unit; an output unit connected and/or integrated with the processing unit; an input unit connected and/or integrated with the processing unit; an activation unit connected and/or integrated with the processing unit for activating operation units of the plurality of networked electrically powered torque tools and/or drive portions of torque tools; and a control unit for controlling operation parameters of each of the plurality of networked electrically powered torque tools and/or drive portions of torque tools to maintain a difference between the operation parameters within a predetermined value. Advantageously, innovations disclosed in this application include operation parameter regulation units for bolting systems having a plurality of networked electrically powered torque tools and/or drive portions of torque tools for simultaneous tightening of industrial threaded fasteners. Indeed SIMULTORC® is achievable with a plurality of networked electrically powered torque tools and/or drive portions of torque tools, particularly those of the handheld and/or mobile variety.
