Abstract
A workpiece stabilizer having a generally cylindrical body can be inserted in the central opening of a multiple jaw chuck and secured therein by tightening a securement nut onto a threaded rod. The end of the threaded rod can be used to engage and stabilize rod stock during its machining. For machining disk-shaped workpieces, a plurality of radially extending arms can be affixed to the cylindrical body portion and cap screws threaded into any of several recesses in the arms, as a function of the workpiece's diameter, to engage and stabilize the disk.
Claims10
A stabilizer for a workpiece being held in a multi-jaw chuck, said stabilizer comprising
- a) a generally cylindrical body portion at least partially insertable in a central opening in the chuck, said body portion having a length, a first end, a second end, and a side wall extending throughout said length between said first end and said second end, openings being formed in said side wall to form thin-walled regions there between;
- b) an aperture extending through said length of said body portion, at least a portion of which is internally threaded;
- c) a cylindrical rod being at least partially threaded on its exterior surface with a thread compatible with said internally threaded portion of said aperture;
- d) at least one member having a stabilizing surface for engaging the workpiece as it is held in the multi-jaw chuck to prevent its axial movement during machining;
- e) a nut having an internally threaded surface which receives said cylindrical rod,
- f) expander means having a tapered outer surface, at least a portion of which is received within said aperture;
- whereby when said nut is tightened upon said cylindrical rod in said aperture, said expander means causes said thin-walled regions to flex outwardly securing said body portion within the central opening of the multi-jaw chuck.
