ABSTRACT:
A rotor assembly machine which transports electric motor rotor laminates from a conveyor to a skewing nest where slots in the laminates are engaged by a plurality of vertical skew blades having a composite structure with two slightly separated spring steel vanes. The reduced width of the slot when the laminates are skewed is accommodated by the vanes of the skew blade flexing together. A particularly novel skew setting mechanism causes the skew blades to be tilted at a predetermined angle which is adjustable by varying the vertical distance between a higher fulcrum member and a lower blade pivot which rotated a predetermined angle causing the laminates to be skewed by an angle inversely related to the distances between the pivot and fulcrum, which distances in a multi-station machine may be separately adjusted thereby producing rotors from different stations with different skew angles. Press means inserts a dummy pin to hold the laminates in position and the lower end of the blades is moved radially outward to release the rotor assemblies out the bottom of the skewing nest.
