Abstract
An armature gripping machine for transferring an armature of an electric motor or similar machine from one location to another, to load or unload a processing station of a production line is provided. The collet and surrounding tube of the gripping machine can be changed quickly and automatically, to accommodate a differently sized armature shaft. A fluid-fed piston mechanism within the gripping machine translates the collet tube along a longitudinal axis, causing the collet to grip or release an armature shaft. The collet may be removed from the gripping machine and replaced with a differently sized collet to accommodate armature shaft of various diameters. Alternatively, the collet and surrounding tube may be removed and replaced as a single unit to accommodate larger variations in armature shaft diameters. The change-over process can be automated.
