Abstract
An improvement to the art of interchangeable spinning machine tool holders has a horizontal disengagement mechanism. A dove tail assembly is used on a spinning receiver and a drilling tool holder combination. In operation a drill press can remain in position above a workpiece. Then the dove tail can be loosened and the drilling tool holder exchanged with another. When the dove tail is tightened the new drilling tool holder is in the proper machining position.
Claims9
An interchangeable spinning tool assembly comprising:
- a spinning drive shaft having an axis of rotation and a distal end;
- a spinning receiver having a horizontal surface and affixed to the spinning drive shaft at the distal end;
- a machining tool holder;
- means for removably connecting the machining tool holder to the spinning receiver perpendicular to the axis of rotation, functioning to enable the removal of the machining tool holder without moving it distally from the distal end;
- said means for removably connecting the machining tool holder to the spinning receiver further comprising a dovetail assembly;
- said dove tail assembly further comprising a movably dovetail member and a stationary dovetail member mounted on the spinning receiver, and a matching slot on the machining tool holder functioning to secure both dovetail members;
- and
- said movable dovetail member being movable in a direction perpendicular to the horizontal surface of the spinning receiver, thereby selfcentering
- the machining tool holder.

An interchangeable spinning tool assembly, comprising:
- a retractable spinning drive shaft having an axis of rotation;
- a spinning receiver having a horizontal surface and affixed to the retractable spinning drive shaft;
- a machining tool holder;
- means for removably connecting the machining tool holder cross axially to the axis of rotation, functioning to allow removal without retracting the retractable spinning drive shaft;
- said means for removably connecting the machining tool holder further comprising a dovetail assembly;
- said dovetail assembly further comprising a moveable dovetail member and a stationary dovetail member mounted on the spinning receiver, and a matching slot on the machining tool holder functioning to secure both dovetail members;
- and
- said movable dovetail member being movable in a direction perpendicular to said horizontal surface of the spinning receiver, thereby functioning to self-center the machining tool holder.
