Abstract

An armature shaft having a cam body extending from one end thereof is inserted into a shaft-receiving transfer block of an armature lamination and shaft assembly machine so that the cam body has a desired angular orientation relative to the axis of rotation of the armature shaft. A stack of laminations with which the shaft is assembled is also angularly oriented.

Claims

1. Apparatus for rotationally orienting an armature shaft having a cam body extending from one end thereof before said shaft is inserted into a shaft-receiving transfer block of an armature lamination and shaft assembly machine so that said cam body has a desired angular orientation relative to the axis of rotation of said armature shaft, said apparatus comprising:

a powered ram movable along a predetermined axis, said ram having a nosepiece provided with a socket having a size and shape to slidably receive the cam body and located relative to said predetermined axis in the same rotational orientation as said desired orientation of said cam body relative to said axis of rotation of said armature shaft;

a movable abutment in confronting alignment with said ram;

an armature shaft support that supports said armature shaft so that its axis of rotation is aligned with said predetermined axis;

said ram being actuatable so that said nosepiece presses on said one end of said armature shaft and the opposite end thereof is extended into engagement with said abutment; and

a shaft rotation mechanism that rotates said shaft while it is pressed between said nosepiece and said abutment in order to align said cam body with said socket while maintaining pressure on the ends of said armature shaft.

2. The apparatus of claim 1 further comprising a hollow transfer tube between said ram nosepiece and said abutment into which said shaft is inserted when said ram is actuated to extend said shaft into engagement with said abutment, said transfer tube having a wall provided with a slot opening to the hollow interior of said tube, and wherein said rotating mechanism comprises a rotationally driven clamp mechanism having a movable clamp jaw located within said slot that engages the portion of said shaft exposed by said slot that compressively clamped said shaft to said tube.

3. The apparatus of claim 2 further comprising an actuator for rotating said movable clamp jaw.
