METHOD AND DEVICE FOR POSITION LOCKED POWER TOOL OPERATION FOR CORRECTION OF UNACCEPTABLE SCREW JOINT TIGHTENING RESULTS. |
摘要 |
<p>A method and a device are provided for locking the operation of a power wrench to the location of an unacceptably tightened screw joint or object with a sensor for at least one tightening parameter. A position sensing system is provided for indicating continuously the position of the power wrench during tightening operations, and a control unit includes a unit for comparing obtained tightening parameter values with predetermined limit values and to provide an OK or a NOK signal in response to those limit values being passed or not for each screw joint. A locking device is provided to lock the power wrench operation to the very position of the screw joint or the object for which a NOK signal has been issued until the unacceptably tightened screw joint has been attended to and the NOK signal is removed.</p> |
