| 摘要 |
<p>The present invention relates to an electric assembly device (200) for tightening of fasteners, said device comprising a housing (210), a rotation motor (215), being drivingly connected to an output shaft (214), said output shaft having a forward portion (217) extending out of said housing (210), and being adapted to carry a coupling means for releasable coupling with said fastener during tightening, said tightening being arranged to be performed along a first axis (Al). The device comprises means (226) for determining an angular displacement (a,ß) of the housing (210) with respect to the said first axis (Al) during tightening of the fastener, and means (220) for controlling the rotation of said motor during tightening using said determined angular displacement (a,ß) of the housing (210).</p> |
