ABSTRACT:
A hand-held, chuck-type part holder provides holding means for a machine part. The hand-held part holder may be secondary holding means for a part which itself is then inserted into a primary machine clamp. The chuck uses standard replaceable collets which may be easily interchanged for different size parts. The collet is actuated by a rod which is moved in turn by an air cylinder which is supported by a handle. The part-gripping collet may be actuated by a tilt switch which provides the automatic clamping action of the collet as the operator turns the holder to the vertical position before inserting or removing a part from the end of the collet. Additionally, a fixture mounted to the bed of the processing machine may be used which guides the part holder into alignment with the primary clamp as it is inserted. The fixture includes pivot and slide means which both support and direct the movement of the part holder.
