ABSTRACT:
An intelligent tightening spindle comprises a drive output; a housing adapted to detachably mount to a moving platform of a multi-tool processing station, with the housing substantially enclosing: at least one electric drive motor having an associated servo amplifier; a gear unit operatively connecting the drive motor to the drive output; a spindle measurement transducer operative to monitor at least one of the drive motor, the gear unit, and the drive output; and a measurement data processing unit in communication with the spindle measurement transducer. An output signal port may have signals applied thereto representing measurement data that has been processed by the measurement data processing unit. The measurement transducer and/or the data processing unit may be removably coupled to the spindle via one or more electrical connectors. One or more of the tightening spindles may be used to form a multi-tool processing station.
