Abstract

A wedge clamp includes a top wall, a bottom wall, a front wall, a rear wall opposite the front wall, and a fluid port traversing from the front wall to the rear wall. The fluid port has a front opening and a rear opening to allow cooling fluid to pass therethrough. In one embodiment, the front opening is a rounded isosceles trapezoid in shape with a pair of parallel substantially planar side walls of different length and a pair of arcuate side walls connecting the pair of planar side walls. The rear opening has a greater surface area proximate the rear wall and a smaller surface area proximate the front opening, resulting in a funnel-shaped opening to cause an increase in velocity of the cooling fluid passing through the fluid port.

First claim

What is claimed is:

1. A wedge clamp comprising:
a top wall;
a bottom wall;
a front wall;
a rear wall opposite the front wall; and
a fluid port traversing from the front wall to the rear wall, the fluid port having a front opening and a rear opening to allow cooling fluid to pass therethrough,
wherein the front opening has a pair of parallel substantially planar side walls of different length and a pair of arcuate side walls connecting the pair of planar side walls.

2. The wedge clamp according to claim 1 , wherein the front opening is a rounded isosceles trapezoid in shape.

3. The wedge clamp according to claim 1 , wherein one of the pair of side walls that is closer to the bottom wall has a greater width and a shorter depth than the other one of the pair of side walls.

4. A wedge clamp comprising:
a top wall;
a bottom wall;
a front wall;
a rear wall opposite the front wall; and
a fluid port traversing from the front wall to the rear wall, the fluid port having a front opening and a rear opening to allow cooling fluid to pass therethrough,
wherein the rear opening has a first wall portion formed in the bottom wall of the wedge clamp and a second wall portion formed in the rear wall of the wedge clamp, and
wherein the first wall portion and the second wall portion are arcuate in shape.

5. The wedge clamp according to claim 1 , wherein the rear opening has a greater surface area proximate the rear wall and a smaller surface area proximate the front opening.

6. The wedge clamp according to claim 1 , wherein the fluid port is formed at a downward angle with respect the bottom wall.

7. The wedge clamp according to claim 4 , wherein the front opening is a rounded isosceles trapezoid in shape.

8. The wedge clamp according to claim 4 , wherein the front opening has a pair of parallel substantially planar side walls of different length and a pair of arcuate side walls connecting the pair of planar side walls.

9. The wedge clamp according to claim 8 , wherein one of the pair of side walls that is closer to the bottom wall has a greater width and a shorter depth than the other one of the pair of side walls.

10. The wedge clamp according to claim 4 , wherein the rear opening has a greater surface area proximate the rear wall and a smaller surface area proximate the front opening.

11. The wedge clamp according to claim 4 , wherein the fluid port is formed at a downward angle with respect the bottom wall.

12. A wedge clamp for securing a cutting insert in a pocket of a cutting tool, the wedge clamp comprising:
a top wall;
a bottom wall;
a front wall;
a rear wall opposite the front wall;
a fluid port traversing from the front wall to the rear wall, the fluid port having a front opening and a rear opening to allow cooling fluid to pass therethrough; and
a threaded bore extending from the front wall to the rear wall for allowing a threaded member to be threaded into a cutting tool to secure a cutting insert in a pocket of a cutting tool.

13. The wedge clamp according to claim 12 , wherein the front opening is a rounded isosceles trapezoid in shape.

14. The wedge clamp according to claim 12 , wherein the front opening has a pair of parallel substantially planar side walls of different length and a pair of arcuate side walls connecting the pair of planar side walls.

15. The wedge clamp according to claim 14 , wherein one of the pair of side walls that is closer to the bottom wall has a greater width and a shorter depth than the other one of the pair of side walls.

16. The wedge clamp according to claim 12 , wherein the rear opening has a first wall portion formed in the bottom wall of the wedge clamp and a second wall portion formed in the rear wall of the wedge clamp.

17. The wedge clamp according to claim 16 , wherein the first wall portion and the second wall portion are arcuate in shape.

18. The wedge clamp according to claim 12 , wherein the rear opening has a greater surface area proximate the rear wall and a smaller surface area proximate the front opening.

19. The wedge clamp according to claim 12 , wherein the fluid port is formed at a downward angle with respect the bottom wall.
