Self-centering dual direction clamping vise with adjustable center support
A vise assembly has a base and a pair of side walls extending from the base and providing guideways. A jaw is configured for guided movement by the guideways. An actuator is coupled to the jaw to cause movement of the jaw. A support supports at least a portion of the actuator. A biasing element is configured to urge the actuator to engage the support.
1. A vise assembly comprising:
a base;
a pair of side walls extending from the base having guideways;
a first jaw and a second jaw, each jaw configured for guided movement by the guideways;
an actuator having a longitudinal axis and coupled to the first jaw and the second jaw to cause selective movement of the first jaw and the second jaw toward and away from each other, the actuator having a fixed annular collar;
a support secured to the base between the first jaw and the second jaw, the support having a single annular flange configured to engage the annular collar on one side;
a retainer configured to move axially with respect to the longitudinal axis and engage the annular collar on a side opposite the single annular flange of the support; and
a spring having a first end joined to the retainer and a second end joined to base or the support, the spring configured to urge the retainer axially toward the single annular flange of the support.
2. The vise assembly of claim 1 , further comprising a lock configured to secure the retainer to the support.
3. The vise assembly of claim 2 wherein the actuator rotates relative to the support and the retainer.
4. The vise assembly of claim 3 , further comprising a pair of spaced apart locking pins coupled to the retainer and slidable in bores in the support, the lock comprising a fastener for each locking pin to secure a position of the locking pin in the bore.
5. The vise assembly of claim 4 wherein the spring comprises a first spring coupled to a first pin of the pair of spaced apart locking pins and a second spring coupled to a second pin of the pair of spaced apart locking pins.
6. The vise assembly of claim 5 wherein the retainer comprises a ring encircling the actuator.
7. The vise assembly of claim 5 wherein each of the first spring and the second spring comprise a compression spring.
8. The vise assembly of claim 4 , wherein the retainer and each of the spaced apart locking pins are movable relative to each other.
9. The vise assembly of claim 1 wherein the support is adjustably secured to the base.
10. The vise assembly of claim 1 wherein the support is slidable upon the base over a selected distance and fixable to the base.
11. The vise assembly of claim 1 wherein the spring comprises a compression spring.
12. The vise assembly of claim 1 wherein the spring is configured to create a spring force due to bending.
13. The vise assembly of claim 1 further comprising a fastener to secure the retainer to the support.
14. The vise assembly of claim 1 wherein the retainer comprises a ring encircling the actuator.
15. The vise assembly of claim 14 further comprising a pair of spaced apart elements coupled to the retainer and slidable in bores in the support and a fastener for each element to secure a position of the element in the bore.
16. The vise assembly of claim 15 wherein the spring comprises a first spring coupled to a first element of the pair of spaced apart elements and a second spring coupled to a second element of the pair of spaced apart elements.
17. The vise assembly of claim 16 wherein the each of the first spring and the second spring comprise a compression spring.
18. The vise assembly of claim 17 wherein an end fastener is secured to each element, where each spring urges each associated end fastener away from the support.
19. The vise assembly of claim 18 wherein the retainer and each of the spaced apart elements are movable relative to each other.
