Abstract

A collet member for a colleting fixture includes a monolithic collet body including a clamping block engaging outer wall and a workpiece engaging inner wall extending circumferentially between first and second end walls, each of the outer wall, the inner wall, and the first and second end walls extending axially from a radial wall to define an internal cavity, and a plurality of rods extending axially from the radial wall within the internal cavity.

First claim

We claim:

1. A collet member for a colleting fixture, the collet member comprising a monolithic collet body including a clamping block engaging outer wall and a workpiece engaging inner wall extending circumferentially between first and second end walls, each of the outer wall, the inner wall, and the first and second end walls extending axially from a radial wall to define an internal cavity, and a plurality of rods extending axially from the radial wall within the internal cavity.

2. The collet member of claim 1 , wherein the radial wall is a first radial wall, the monolithic collet body further including a second radial wall, wherein each of the outer wall, the inner wall, the first and second end walls, and the plurality of rods extend axially between first and second radial walls, such that the first end wall, the second end wall, the outer wall, the inner wall, the first radial wall, and the second radial wall together enclose the internal cavity.

3. The collet member of claim 1 , wherein the first and second end walls include a plurality of openings.

4. The collet member of claim 1 , wherein the radial wall includes a plurality of openings.

5. The collet member of claim 1 , further comprising at least one rib extending radially from the inner wall to the outer wall.

6. The collet member of claim 5 , wherein the at least one rib includes a plurality of openings.

7. The collet member of claim 5 , wherein the at least one rib extends axially from the radial wall into the interior cavity.

8. The collet member of claim 5 , wherein the at least one rib extends radially from a center point of the inner wall to a center point of the outer wall.

9. The collet member of claim 5 , further comprising a fastener hole extending from the outer wall to the inner wall and through the at least one rib.

10. The collet member of claim 1 , wherein the outer wall comprises a semi-cylindrical outer wall.

11. The collet member of claim 1 , wherein the inner wall comprises a semi-cylindrical inner wall defining a semi-cylindrical workpiece engaging surface.

12. The collet member of claim 1 , wherein the inner wall comprises a plurality of radially inward extending protrusions defining a plurality of discrete workpiece engaging surfaces.

13. The collet member of claim 1 , wherein the outer wall comprises a plurality of radially outward extending protrusions defining a plurality of discrete clamping block engaging surfaces.

14. The collet member of claim 1 , further comprising a fastener hole extending from the outer wall to the inner wall.

15. The collet member of claim 1 , wherein the collet member is constructed using additive manufacturing.

16. The collet member of claim 1 , wherein the collet member comprises at least one of stainless steel, aluminum, and copper.

17. The collet member of claim 1 , wherein each of the plurality of rods is cylindrical.

18. The collet member of claim 1 , further comprising at least one rib extending radially from the inner wall to the outer wall, wherein each of the first and second end walls, the radial wall, and the at least one rib includes a plurality of openings.

19. A colleting fixture comprising:
first and second clamping blocks; and
first and second collet members secured to corresponding ones of the first and second clamping blocks, with the first and second clamping blocks being joinable such that the first and second collet members together define a workpiece engaging collet;
wherein at least one of the first and second collet members comprises a monolithic collet body including a clamping block engaging outer wall and a workpiece engaging inner wall extending circumferentially between first and second end walls, each of the outer wall, the inner wall, and the first and second end walls extending axially from a radial wall to define an internal cavity, and a plurality of rods extending axially from the radial wall within the internal cavity.

20. The colleting fixture of claim 19 , wherein the at least one of the first and second collet members includes at least one rib extending radially from the inner wall to the outer wall, wherein each of the first and second end walls, the radial wall, and the at least one rib includes a plurality of openings.
