Abstract
An adjustable clamping jaw assembly for a lathe chuck. The jaw is adjustable by assuming any one of several discrete positions relative to an elongated jaw base upon which it is mounted. Such adjustment is carried out by a keyway in the elongated jaw base, or key, and a rotatable tumble block having a plurality of keyways.
Claims16
An incrementally adjustable jaw assembly for machine tool chucks, comprising in combination;
- a. a jaw base attached to a master jaw of a chuck and a top jaw mounted for incremental relative movement with respect to said jaw base,
- b. tumble block and key means for providing an incrementally adjustable abutment between said top jaw and said jaw base which determines the relative position between said top jaw and said jaw base,
- C. said tumble block including a multi-faceted block having differently positioned keyways in its faces, said key means being engageable with a selected of one said keyways for adjustably positioning said incremental adjustable abutment of said tumble block relative to said jaw base, and means for securing said top jaw to said tumble block and for clamping said top jaw and said jaw base together.
An incrementally adjustable jaw assembly for machine tool chucks which includes a jaw base adapted for limited movement between open and closed positions, a top jaw carried by said jaw base for incremental positioning thereof to accommodate for workpieces of different dimensions, and means for locking said top jaw to said jaw base in a plurality of incremental positions with respect thereto, said means including a multi-faceted block having differently positioned keyways in its faces, key means engageable with a selected one of said keyways for determining the incremental position of said top jaw relative to said jaw base, and a locking bolt passing through said multi-faceted block and securely clamping said top jaw, said block and said jaw base together.
