Electric screw driver i.e. spindle, for use on e.g. machine, to perform screwing operation, has connector coupled to support fixed on fixed surface and configured to assure motor supply and transmission of information from measurement unit

摘要

The driver (1) has an output shaft (2) to rotate a screwing tool, and a torque sensor (4) comprising a measurement unit (6) to measure torsional deformation of a deforming element (5). A motor (8) rotates the shaft, and a connector (12) allows power supply of the motor. The element is secured to a fixing surface to secure the driver on a frame (B). The connector is coupled to a support mounted on the surface in secured manner to rotate relative to a longitudinal axis (X) of the shaft and configured to assure power supply of the motor and transmission of information from the unit.
