US 3,937,111 A · Adjustable live center adapter

Abstract

An adapter for rendering a live center for machines adjustable for adjustable centering of work pieces may comprise a generally conical body having a conical recess formed therein and adapted to receive the conical extremity of a rotatable live center element of a live center mechanism. A conical surface may be formed at one extremity of the conical body and may be disposed for receiving contact within the center hole of a work piece. The generally conical body may include pivot means internally thereof which may be disposed for contact with the conical extremity of a rotatable live center element. An adjustment mechanism may be provided for the conical body and may also engage the rotatable live center element, the adjustment mechanism being manipulated to impart controllable pivotal movement of the body relative to the rotatable live center element to achieve controlled shifting of the axis of the adapter relative to the axis of the rotatable live center element.

Dependent claims

A center adjustment adapter for rendering a live center for machines adjustable for controlled positioning of work pieces relative to the work rotating axis of such machines, said adapter comprising:

a body having a generally conical recess formed therein, said recess being adapted to receive the conical extremity of a rotatable live center element in non-rotatable relation therein;
conical surface means being formed on the exterior of said body and being located for receiving contact within the center hole of a work piece to be rotatably supported by such machines;
fixed pivot means being fixedly located within said body and being positioned for pivotal contact with the conical surface of said rotatable live center element near the pointed extremity thereof;
and
a plurality of adjustment screws being carried by said body and being located for engagement with said rotatable live center element at a position remote from said conical surface thereof, said adjustment screws, upon being controllably moved, imparting pivotal movement to said body relative to said rotatable live center element, said pivotal movement being about said fixed pivot means.

A center adjustment adapter for rendering a live center for machines adjustable for controlled positioning of work pieces relative to the work rotating axis of such machines, said adapter comprising:

a body having a generally conical recess formed therein, said recess being adapted for receiving the conical extremity of a rotatable live center element in non-rotatable relation therein, said body having a generally cylindrical annular portion defining one extremity of said body;
generally conical surface means being formed on the exterior of said body and being located for receiving contact within the center hole of a work piece to be rotatably supported by such machines;
fixed pivot means being fixedly located within said body and being positioned for pivotal contact with the conical surface portion of a rotatable live center element near the pointed extremity thereof;
and
a chuck mechanism being located at one extremity of said body and having a plurality of individually adjustable jaws, said jaws being disposed for adjustable contacting relation with said rotatable live center element remote from said conical surface portion thereof and being individually manipulatable for controlling the fixed orientation of the axis of said body relative to the axis of said rotatable live center element.
