Claims
- 1. A machining vise, comprising:a main body having a recess; a stationary vise jaw removably mounted at a mid-point on the main body; a first movable slide and a second movable slide mounted in the recess, wherein a first vise jaw is mounted to the first movable slide and a second vise jaw is mounted to the second movable slide; means for moving the first and second movable slides; a controlled release assembly associated with the first movable slide to control the movement of the first movable slide and the second movable slide, the controlled release assembly including an offset adjustment mechanism and a spring biasing mechanism.
- 2. The machining vise according to claim 1, wherein the controlled release assembly causes the first movable slide to release a work piece before the second movable slide releases a work piece.
- 3. The machining vise according to claim 1, wherein the offset adjustment mechanism is formed within the main body and is associated with the first movable slide to limit movement of the first movable slide as a work piece is released from the machining vise.
- 4. The machining vise according to claim 3, wherein the offset adjustment mechanism includes a stationary screw member and a stop block threaded thereto, the stop block being moved by rotation of the stationary screw member to adjust an offset distance.
- 5. The machining vise according to claim 3, wherein the spring biasing mechanism includes at least one spring and a stationary retainer plate, and the spring and stationary retainer plate force the first movable slide away a predetermined offset distance before the first movable slide engages the offset adjust mechanism and the second movable slide begins to move for the release of a work piece.
- 6. The machining vise according to claim 5, wherein the first vise jaw is removably mounted to the first movable slide and the second vise jaw is removably mounted to the second movable slide.
- 7. The machining vise according to claim 1, wherein the spring biasing mechanism includes at least one spring and a stationary retainer plate, and the spring and stationary retainer plate force the first movable slide away a predetermined offset distance as the means for moving is actuated to release a work piece.
- 8. The machining vise according to claim 1, wherein the first vise jaw is removably mounted to the first movable slide and the second vise jaw is removably mounted to the second movable slide.
- 9. The machining vise according to claim 1, wherein the means for moving includes a drive screw.
- 10. The machining vise according to claim 9, wherein the drive screw includes a proximal end and a distal end, and the distal end is threaded to engage a threaded opening in the second movable slide to thereby control movement of the second movable slide within the main body.
- 11. The machining vise according to claim 10, wherein the drive screw includes a flange member which engages the first movable slide to move the first movable slide within the main body as the drive screw is rotated.
- 12. The machining vise according to claim 11, wherein rotation of the drive screw causes the second movable slide to move until the second movable slide engages a work piece and thereafter continued rotation causes the flange member to engage the first movable slide to move the first movable slide engages a work piece.
- 13. The machining vise according to claim 12, wherein the controlled release assembly causes the first movable slide to release a work piece before the second movable slide releases a work piece.
- 14. A machining vise, comprising:a main body having a longitudinal axis; a stationary vise jaw mounted on the main body; at least a first movable slide mounted in the main body for guiding a first movable vise jaw along the longitudinal axis, the first movable slide including a first upwardly extending knuckle on which the first movable vise jaw is mounted; the first knuckle includes a pair of resiliently biased plungers shaped and dimensioned to engage the first movable vise jaw, said resiliently biased plungers extending substantially perpendicularly to said longitudinal axis and engaging the first movable vise jaw to releasably couple the first movable vise jaw on the first knuckle; and means for moving the first movable slide, said resiliently biased plungers extending from opposite sides of said first knuckle, and resiliently engaging first and second camming surfaces formed in a recess in the first movable vise jaw and causing the first movable vise jaw to be drawn downwardly under the pressure of the resiliently biased plungers.
