Power tool gear-train and torque overload clutch therefor

ActiveUS7644783B2Shorten the lengthDrilling rodsConstructionsGear wheelGear train

A power tool transmission is described in which an overload clutch mechanism is arranged to provide a relatively compact power tool. A torque adjustment dial is arranged between the visible portions of the motor housing and the gearbox, and the dial is coupled to a compression spring such that rotation of the dial cause the spring to be compressed or decompressed, thereby adjusting the torque at which the clutch overloads and ratchets. The compression spring is arranged at least partially between the motor and gearbox or gear train, in a space which conventional power tools do not utilized for this purpose. Thus, the dimensions of the power tool's transmission can be reduced with respect to conventional power tools. Furthermore, the space on the gearbox immediately behind a chuck can be used for another purpose other than accommodating the adjustment collar, as is the case with conventional power tools.

Control method and control unit for impact type screw fastening device

ActiveUS7770658B2Improve accuracyImprove fastening accuracyDrilling rodsConstructionsControl theoryElectrical current

An object is to improve accuracy of tightening torque and to shorten time necessary for fastening a screw in an impact type screw fastening device that uses an electric motor as a rotation driving source. A control method for the impact type screw fastening device that uses an electric motor as a rotation driving source includes the steps of driving the motor to rotate by supplying current to the motor intermittently so that torque exerted on a load by rotation of the motor becomes like pulses on the time axis, and controlling the current of every time of each pulse so that an increment of every time of each pulse of the torque after the torque reaches a target approach torque TQN that is a first set value becomes smaller than that before it reaches the target approach torque TQN.

Power tool (11) may include a motor and oil pulse unit (22) that generates an elevated torque. Oil pulse unit (22) may be coupled to the motor and have output shaft (18). When load acting on output shaft (18) is less than a predetermined value, rotating torque generated by the motor is directly transmitted to output shaft (18). When the load acting on output shaft (22) exceeds the predetermined value, an elevated torque is generated by oil pulse unit (22) and applied to output shaft (18). Output shaft (18) may be connected to load shaft (12). A socket may be attached to the distal end of load shaft (12). Power tool (11) may further include detecting device (20) for detecting change in rotational angle of output shaft (18) and the direction of rotation thereof, and a control device. The detecting device (20) may output signals corresponding to a state of output shaft (18) to the control device. The control device may store the state of output shaft (18) at predetermined interval. Preferably, the control device may further determine a generating time, at which oil pulse unit (22) generates the elevated torque, based upon the state of output shaft (18).

Apparatus for controlling a fastener driving tool, with user-adjustable torque limiting control

ActiveUS7331406B2Derricks/mastsSpannersElectric machineryHand held

An improved hand-held fastener driving tool is provided with an adjustable torque limiting control. The tool is portable, and is electrically powered using either a battery pack or a power cord as a power source. The tool drives collated fasteners (e.g., screws) into solid objects. The motor current is measured to determine the amount of torque being applied to a screw by the motor and mechanical drive components. As the screw bottoms out, the motor torque increases to a point where it exceeds the user-adjusted torque limiting control. The motor is automatically turned off at that point, thereby preventing the screw from being stripped.
