ABSTRACT:
An indexing chuck for performing multiple machining operations on a workpiece is disclosed in which the clamping and machining forces applied to the workpiece do not distort the indexing chuck or cause bell mouthing. The indexing chuck is fabricated by securely connecting a top plate, a bottom plate, side plates and a back plate to form a housing having an enlarged aperture therein for accommodating the workpiece. An indexing jaw assembly is removably disposed within the top plate and a clamping jaw assembly is removably disposed in the bottom plate diametrically opposed the indexing jaw assembly. The indexing jaw and clamping jaw assemblies are adapted for securing the workpiece therebetween and for rotating the workpiece through preselected angles. Hydraulic activators apply chucking and unchucking forces to the workpiece and activate a bidirectional motor within the top plate of the chuck housing for indexing and locking the workpiece. The indexing jaw assembly is readily removable from the indexing chuck for changing the rotation angles through which a workpiece is to be rotated for various machining operations. Electrical sensors disposed within the chuck housing provide electrical signals for indexing and locking the workpiece. The indexing chuck is capable of being operated either manually or with numerical control.
