Abstract

A flash-removal tool comprises a tool body, extending along a longitudinal tool axis, and a tooth, projecting from the tool body in a first direction. The flash-removal tool further comprises an engagement surface, perpendicular to the longitudinal tool axis and located a preselected distance away from the tooth along the longitudinal tool axis. The tooth comprises a shearing surface, facing in the first direction and located an offset distance away from the longitudinal tool axis in a second direction. The first direction and the second direction are orthogonal to each other and define a plane, perpendicular to the longitudinal tool axis.

First claim

What is claimed is:

1. A flash-removal tool, comprising:
a tool body, extending along a longitudinal tool axis and comprising an exterior circumferential surface, wherein:
the exterior circumferential surface extends between a first end surface of the tool body and a second end surface of the tool body; and
the longitudinal tool axis is a central longitudinal axis of the tool body;

a tooth, projecting from the tool body in a first direction along a first axis and fixed at all times relative to the tool body;
an engagement surface, perpendicular to the longitudinal tool axis and located a preselected distance away from the tooth along the longitudinal tool axis; and
a positioning groove, recessed in the exterior circumferential surface of the tool body, wherein:
the positioning groove is configured to position the flash-removal tool against a workpiece;
the engagement surface is located adjacent to the first end surface and forms a longitudinal end-wall of the positioning groove;
the longitudinal end-wall is configured for positioning the workpiece relative to the flash-removal tool in a direction parallel to the longitudinal tool axis;
the tooth comprises a shearing surface;
the shearing surface faces in the first direction;
the shearing surface is offset an offset distance away from the longitudinal tool axis in a second direction along a second axis;
the shearing surface comprises a shearing edge, all of the shearing edge is parallel to the longitudinal tool axis of the tool body;
the first axis and the second axis are orthogonal to each other and define a virtual plane, which contains the first axis and the second axis and which is perpendicular to the longitudinal tool axis and to the shearing surface;
the positioning groove extends longitudinally between the first end surface and the tooth; and
the positioning groove faces in the first direction.

2. The flash-removal tool according to claim 1 , wherein the engagement surface is defined on the tool body, such that the preselected distance is non-adjustable.

3. The flash-removal tool according to claim 1 , further comprising an extendable portion, movable with respect to the tool body to adjust the preselected distance.

4. The flash-removal tool according to claim 3 , wherein:
the extendable portion comprises a telescoping portion, coupled to the tool body; and
the engagement surface is defined on the telescoping portion.

5. The flash-removal tool according to claim 4 , further comprising a lock, operable to selectively lock the telescoping portion in position relative to the tool body after the preselected distance is adjusted.

6. The flash-removal tool according to claim 5 , wherein the lock comprises:
a detent, located on one of the telescoping portion or the tool body; and
a plurality of catches, arranged longitudinally on another of the telescoping portion or the tool body, and wherein each one of the catches is configured to interfere with the detent when the telescoping portion is correspondingly adjusted relative to the tool body.

7. The flash-removal tool according to claim 1 , wherein the positioning groove comprises a cylindrically contoured portion, extending parallel to the longitudinal tool axis.

8. The flash-removal tool according to claim 7 , wherein the positioning groove further comprises a tapered portion, extending longitudinally between the cylindrically contoured portion and the tooth and parallel to the longitudinal tool axis.

9. The flash-removal tool according to claim 7 , further comprising a secondary groove, defined in the tool body, wherein the tooth divides the tool body longitudinally into two sides, wherein the positioning groove extends longitudinally on one of the two sides, and wherein the secondary groove extends longitudinally on another of the two sides and faces in the first direction.

10. The flash-removal tool according to claim 9 , wherein the secondary groove comprises a cylindrically contoured secondary portion, extending parallel to the longitudinal tool axis.

11. The flash-removal tool according to claim 10 , wherein the secondary groove further comprises a tapered secondary portion, parallel to the longitudinal tool axis and extending longitudinally between the cylindrically contoured secondary portion and the tooth.

12. The flash-removal tool according to claim 1 , further comprising a secondary groove, defined in the tool body, wherein the tooth divides the tool body longitudinally into two sides, wherein the positioning groove extends longitudinally on one of the two sides, and wherein the secondary groove extends longitudinally on another of the two sides and faces in the first direction.

13. The flash-removal tool according to claim 12 , wherein the secondary groove comprises a cylindrically contoured secondary portion, extending parallel to the longitudinal tool axis.

14. The flash-removal tool according to claim 13 , wherein the secondary groove further comprises a tapered secondary portion, parallel to the longitudinal tool axis and extending longitudinally between the cylindrically contoured secondary portion and the tooth.

15. The flash-removal tool according to claim 1 , further comprising a second tooth, and wherein the longitudinal tool axis is located between the tooth and the second tooth.

16. The flash-removal tool according to claim 15 , wherein the second tooth is located the preselected distance away from the engagement surface along the longitudinal tool axis.

17. The flash-removal tool according to claim 1 , wherein the tooth is monolithic with the tool body.

18. The flash-removal tool according to claim 1 , wherein the tooth is formed separately from, and coupled to, the tool body.

19. The flash-removal tool according to claim 1 , wherein the tooth is located at the second end.

20. The flash-removal tool according to claim 1 , wherein the tooth is spaced apart from the second end along the longitudinal tool axis.
