Machine for automatically assembling armature cores and commutators therefor

Abstract

Abstract FEEDING MECHANISM SUCCESSIVELY BRINGS ARMATURE CORES AND COMMUTATORS THEREFOR TO AN ASSEMBLY STATION WHEN THEY ARE HELD IN COAXIAL ENDWISE SPACED RELATIONSHIP AND WHERE ROTATION IMPARTING MECHANISM BRINGS EACH ARMATURE CORE AND COMMUTATOR PAIR INTO CORRECT ANGULAR RELATIONSHIP. A RAM THEN PUSHES THE COMMUTATOR AXIALLY TOWARDS THE ARMATURE CORE WITH THE TERMINAL TANGS ON THE COMMUTATOR FACING THE CORE, AND PRESSES IT ONTO THE SHAFT THEREOF, MOVING THE COMMUTATOR THROUGH A DIE WHICH STRAIGHTENS TANGS THAT MAY BE ASKEW. THE TANG STRAIGHTENING DIE HAS A ROUND HOLE THAT SLIDABLY ACCEPTS THE COMMUTATOR, AND LONGITUDINALLY EXTENDING CIRCUMFERENTIALLY SPACED PARALLEL GROOVES THAT SLIDABLY ACCOMMODATE THE TANGS. WHEN THE COMMUNATOR REACHES PROPER POSITION ON THE ARMATURE SHAFT, AND WHILE STILL IN THE DIE, A TANG SHARPING MEMBER HAVING CIRCUMFERENTIALLY SPACED PARALLEL FINGERS, ONE FOR EACH TANG, TELESCOPES OVER THE COMMUTATOR, EACH FINGER MOVING ALONG ONE OF THE GROOVES TO ENGAGE UNDER THE TANG THEREIN AND LIFT IT INTO CONTACT WITH THE BOTTOM OF THE GROOVE.
