Abstract
The present invention relates to torque application tools, such as an electronic torque screwdriver, with a multiple axis gyroscope (such as a 3-axis gyroscope or other type of gyroscope) and torque sensor that allows for simultaneous or sequential measurement of torque and angle around the axis of the tool. Targets for torque and angle measurements may be used to create algorithms to detect breakaway torque, residual torque, or to perform error proofing to ensure unique fasteners are tightened.
Claims12
A tool adapted to apply torque to a work piece, the tool comprising:
- a torque sensor adapted to measure an amount of torque applied to the work piece;
- a gyroscope adapted to measure an amount of angular rotation applied to the work piece;
- and
- a controller configured with a minimum angle value and adapted to determine a residual torque value of the work piece based on the amount of torque applied to the work piece when the amount of angular rotation substantially meets the minimum angle value.
