    Abstract: An electronic torque wrench or other tool, and a method and a computer program for using the same, are disclosed. The disclosed systems allow a user to operate the tool in either a manual mode or automatic mode. In the manual mode, torque or angle targets are input into the wrench before the torqueing operation, and in the automatic mode, preset torque or angle targets are selected by the user. A user can also lock the tool so only a specific torqueing operation can be used without unlocking the tool. The torque and angle values can be input simultaneously such that a work piece can be torqued to a predetermined torque and angle without separate operations. An indicator can also be implemented that indicates the progress of the torqueing operation.

First distortion sensors and second distortion sensors are arranged on the strain body at spaced points in the axial direction of the strain body for measuring an amount of distortion of the strain body. A microprocessor chip has functions including computation of a tightening torque which is corrected for errors due to changes in a point of effort where a tightening force is applied by a user. The correction is based on the detection result of the first distortion sensors and the second distortion sensors. An output portion outputs the corrected tightening torque measurement value.

  • Patent number: 8215258
    Abstract: A novel safety-equipped chuck wrench is provided, as well as a method for using the same. The safety-equipped chuck wrench comprises a chuck wrench and a safety device associated with the chuck wrench, where the safety device comprises an alarm, a power source and an alarm activation switch. The alarm activation switch causes the alarm to activate so long as the chuck wrench is engaged in a chuck, subject to de-activation by engagement of a cut-off switch, if any. The alarm may be an audible alarm, a visual alarm, or both. The safety-equipped chuck wrench may include a mechanism for temporarily disabling the alarm, preferably through the use of a cutoff switch.

    Abstract: A mechanical torque wrench for engaging a workpiece, including a wrench body, a wrench head with a workpiece engaging portion and a bar, the wrench head being pivotably secured to the wrench body, a set spring, a pawl disposed between the bar and the set spring, and a dial screw, wherein rotation of the dial screw in a first direction compresses the set spring. A resistive element is coupled to the dial screw and produces an output signal. A first sensor produces a first output signal that is proportional to an amount of rotation of the mechanical torque wrench. A processor converts the resistive element output signal into an equivalent torque value indicating a preset torque to be applied by and converts the first output signal into a first angle value. A user interface includes a display for displaying the equivalent torque value. The application of a torque greater than the preset torque causes the wrench head to pivot relative to the wrench body.

  • Patent number: 8171827
    Abstract: The invention relates to a power screwdriver (10) comprising a motor (12) and a control circuit (22) which switches the motor (12) off by means of a switch-off signal (s_Stop) when it reaches a preset desired torque value (Md_Soll), and a supporting arm (18) which absorbs energy during screwing. The invention is characterized by a voltage limiting circuit (46) that limits the motor voltage (u_Mot) occurring on the motor (12) when the energy stored in the supporting arm (18) of the motor (12), which is driven as the generator and rotates counter to the direction of drive, is dissipated, to a predetermined limiting voltage (u_Lim). The limiting voltage (u_Lim) is fixed in such a manner that the motor (12) is capable of rotating without counter-torque counter to the direction of drive when operated in the generator mode and that yet no inadmissible overvoltages occur.
