Abstract

A manufacturing apparatus is presented. The manufacturing apparatus comprises a tool support movable along multiple axes; a tool mounted on the tool support for performing a manufacturing operation on a workpiece; and an ancillary device releasably mounted on the tool support and used in conjunction with the tool, the ancillary device moveable along at least a first axis independent of the movement of the tool.

First claim

What is claimed is:

1. A manufacturing apparatus comprising:
a tool support movable along multiple axes;
a tool mounted on the tool support for performing a manufacturing operation on a workpiece; and
a friction stir spot welding device used in conjunction with the tool, the friction stir spot welding device movable along at least a first axis independent of the movement of the tool, and the friction stir spot welding device comprising:
a base;
a number of fastening braces attached to the base, the fastening braces configured to releasably mount the friction stir spot welding device to the tool support via fasteners;
a material capture ring attached to the base and concentric with the tool when the fastening braces are connected to the tool support; and
a number of pistons attached to the base.

2. The manufacturing apparatus of claim 1 , wherein the friction stir spot welding device is releasably mounted on a flange of the tool support.

3. The manufacturing apparatus of claim 2 , wherein the tool support comprises a drive configured to rotate the friction stir spot welding device around the first axis.

4. The manufacturing apparatus of claim 2 further comprising:
a clamping assembly releasably mounted on the tool support for movement along the at least first axis independent of the movement of the tool, the clamping assembly comprising at least one clamping device for applying clamping pressure to the workpiece.

5. The manufacturing apparatus of claim 4 , wherein the friction stir spot welding device further comprises a number of pneumatic ports configured to supply pneumatic power for clamping during friction stir spot welding.

6. The manufacturing apparatus of claim 4 , wherein the at least one clamping device comprises a roller clamp for engaging the workpiece and means for biasing the roller clamp against the workpiece.

7. The manufacturing apparatus of claim 1 , wherein the friction stir spot welding device further comprises:
an angular contact bearing configured to provide a number of axis locations for the friction stir spot welding device.

8. The manufacturing apparatus of claim 1 , wherein the friction stir spot welding device further comprises a stop attached to the base, the stop configured to aid alignment in attaching the friction stir spot welding device to the tool support.

9. The manufacturing apparatus of claim 1 , wherein the friction stir spot welding device further comprises a number of o-rings, each o-ring positioned between one of the number of pistons and the base.

10. A manufacturing apparatus comprising:
a tool support movable along multiple axes, the tool support comprising a number of flanges;
a tool mounted on the tool support for performing a manufacturing operation on a workpiece; and
a friction stir spot welding device used in conjunction with the tool, the friction stir spot welding device moveable along at least a first axis independent of the movement of the tool, and the friction stir spot welding device comprising:
a base;
a number of fastening braces attached to the base, the fastening braces configured to releasably mount the friction stir spot welding device to the tool support via fasteners;
a material capture ring attached to the base and concentric with the tool when the fastening braces are connected to the tool support; and
a number of pistons attached to the base; and

a clamping assembly releasably mounted on at least one of the number of flanges of the tool support for movement along the at least first axis independent of the movement of the tool, the clamping assembly comprising at least one clamping device for applying clamping pressure to the workpiece, the at least one clamping device comprising a roller clamp for engaging the workpiece and means for biasing the roller clamp against the workpiece.

11. The manufacturing apparatus of claim 10 , wherein the friction stir spot welding device further comprises:
an angular contact bearing configured to provide a number of axis locations for the friction stir spot welding device.

12. The manufacturing apparatus of claim 10 , wherein the friction stir spot welding device further comprises a stop attached to the base, configured to aid alignment in attaching the friction stir spot welding device to the tool support.

13. The manufacturing apparatus of claim 10 , wherein the friction stir spot welding device further comprises a number of o-rings, each o-ring positioned between one of the number of pistons and the base.

14. The manufacturing apparatus of claim 10 , wherein the friction stir spot welding device further comprises a number of pneumatic ports configured to supply pneumatic power for clamping during friction stir spot welding.

15. A manufacturing apparatus comprising:
a tool support movable along multiple axes;
a tool mounted on the tool support for performing a manufacturing operation on a workpiece;
a structural positioning system releasably mounted on the tool support and used in conjunction with the tool, the structural positioning system moveable along at least a first axis independent of the movement of the tool; and
a clamping assembly releasably mounted on the tool support for movement along the at least first axis independent of the movement of the tool, the clamping assembly comprising at least one clamping device for applying clamping pressure to the workpiece.

16. The manufacturing apparatus of claim 15 , wherein the structural positioning system comprises:
a number of locator rollers; and
a number of tension rollers.

17. The manufacturing apparatus of claim 15 , wherein the at least one clamping device comprises a roller clamp for engaging the workpiece and means for biasing the roller clamp against the workpiece.

18. The manufacturing apparatus of claim 15 , wherein the tool support comprises a number of flanges and the clamping assembly is releasably mounted on at least one of the number of flanges.
