1results about How to "Play a foolproof role" patented technology

The utility model discloses a kind of prevent fool tooling for magnetic steel installation, including substrate, multiple positioning guide grooves are opened in annular array on the substrate, and prevent fool device is set in the left and right sides of positioning guide groove;The prevent fool device includes bearing, longitudinal setting pivot is set in the bearing, the top of the pivot is set to drag plate, prevent fool magnet is fixedly set on the drag plate, when motor magnetic steel is passed from top to bottom in positioning guide groove, if the magnetism with prevent fool magnet is same, then repel each other, prevent fool magnet is in the state of inclination under the action of pivot, if the magnetism with prevent fool magnet is different, then attract each other, prevent fool magnet is perpendicular to motor magnetic steel under the action of pivot.The utility model can prompt the motor magnetic steel of installation by setting prevent fool device, avoid installation error, prevent fool effect is played to the installation of motor magnetic steel, to improve the product quality of motor.
