Abstract

The present disclosure relates generally to crimping tool for crimping a cup washer to a bolt. The crimping tool includes several alignment features that prevent the crimping tool from being used in an orientation other than a desired orientation.

First claim

What is claimed:

1. A crimping tool operative to crimp a cup washer to a bolt, wherein the bolt includes a head, at least one tool engagement surface formed on the head and at least one depression formed around a perimeter of the bolt, wherein the cup washer includes a cup for receiving the head of the bolt, a rim disposed around a perimeter of the cup, and an opening formed in the cup and the rim, the crimping tool comprising:
a crimp former, comprising:
an interior space operative to receive the bolt head;
an outer crimp former surface surrounding the interior space;
at least one bolt engagement surface disposed at least partially within the interior space;
a cup washer engagement surface extending from a distal end of the outer crimp former surface;
at least one crimping tang extending distally a first distance from the cup washer engagement surface;

a clocking body disposed on the outer crimp former surface;
a clocking tab extending distally from the clocking body at least the first distance from the cup washer engagement surface;
wherein engagement of the at least one bolt engagement surface with the at least one tool engagement surface of the bolt, and insertion of the clocking tab into the cup washer opening, is operative to position the at least one crimping tang at at least one desired location with respect to the at least one depression.

2. The crimping tool of claim 1 , further comprising:
a proximal end;
a distal end;
a handle disposed at the proximal end; and
a handle flange disposed distal of the handle.

3. The crimping tool of claim 2 , wherein the crimp former is disposed at the distal end.

4. The crimping tool of claim 2 , further comprising:
a shaft operatively coupled to the handle and the crimp former; and
a slide hammer in sliding engagement with the shaft, the slide hammer including a proximal slide hammer flange and a distal slide hammer flange.

5. The crimping tool of claim 4 , wherein the slide hammer is disposed around the shaft.

6. The crimping tool of claim 1 , further comprising a crimp former flange disposed proximal of the crimp former.

7. The crimping tool of claim 1 , further comprising an orientation tab extending distal of the cup washer engagement surface.

8. The crimping tool of claim 7 , wherein:
the orientation tab is operative to engage at least one of the at least one depression; and
engagement of the at least one bolt engagement surface and the orientation tab with the bolt, and insertion of the clocking tab into the cup washer opening, is operative to position the at least one crimping tang at at least one desired location with respect to the at least one depression.

9. The crimping tool of claim 1 , further comprising:
a slot formed through the clocking body; and
a fastener extending through the clocking body slot, the fastener operative to attach the clocking body in sliding engagement with the outer crimp former surface.

10. The crimping tool of claim 9 , wherein the fastener comprises a bolt.

11. The crimping tool of claim 9 , wherein the fastener allows the clocking body to circumferentially slide around the outer crimp former surface a second distance permitted by the clocking body slot.

12. The crimping tool of claim 11 , wherein the second distance permits a position of the clocking tab with respect to the outer crimp former surface to be adjusted to account for tolerance stack-ups in the bolt, cup washer, and crimp former combination.

13. The crimping tool of claim 1 , wherein the clocking tab is positioned circumferentially on the outer crimp former surface such that the clocking tab will engage the cup washer rim if an attempt is made to place one of the at least one crimping tangs into the cup washer opening.

14. A crimping tool operative to crimp a cup washer to a bolt, wherein the bolt includes a head, at least one tool engagement surface formed on the head and at least one depression formed around a perimeter of the bolt, wherein the cup washer includes a cup for receiving the head of the bolt, a rim disposed around a perimeter of the cup, and an opening formed in the cup and the rim, the crimping tool comprising:
a proximal end;
a distal end;
a handle disposed at the proximal end;
a crimp former disposed at the distal end, the crimp former comprising:
an interior space operative to receive the bolt head;
an outer crimp former surface surrounding the interior space;
at least one bolt engagement surface disposed at least partially within the interior space;
a cup washer engagement surface extending from a distal end of the outer crimp former surface;
at least one crimping tang extending distally a first distance from the cup washer engagement surface;

a shaft operatively coupled to the handle and the crimp former; and
a slide hammer in sliding engagement with the shaft;
a clocking body disposed on the outer crimp former surface;
a clocking tab extending distally from the clocking body at least the first distance from the cup washer engagement surface;
wherein engagement of the at least one bolt engagement surface with the at least one tool engagement surface of the bolt, and insertion of the clocking tab into the cup washer opening, is operative to position the at least one crimping tang at at least one desired location with respect to the at least one depression.

15. The crimping tool of claim 14 , wherein the slide hammer is disposed around the shaft.

16. The crimping tool of claim 14 , further comprising an orientation tab extending distal of the cup washer engagement surface.

17. The crimping tool of claim 16 , wherein:
the orientation tab is operative to engage at least one of the at least one depression; and
engagement of the at least one bolt engagement surface and the orientation tab with the bolt, and insertion of the clocking tab into the cup washer opening, is operative to position the at least one crimping tang at at least one desired location with respect to the at least one depression.

18. The crimping tool of claim 14 , further comprising:
a slot formed through the clocking body; and
a fastener extending through the clocking body slot, the fastener operative to attach the clocking body in sliding engagement with the outer crimp former surface.

19. The crimping tool of claim 18 , wherein:
the fastener allows the clocking body to circumferentially slide around the outer crimp former surface a second distance permitted by the clocking body slot;
the second distance permits a position of the clocking tab with respect to the outer crimp former surface to be adjusted to account for tolerance stack-ups in the bolt, cup washer, and crimp former combination; and
the clocking tab is positioned circumferentially on the outer crimp former surface such that the clocking tab will engage the cup washer rim if an attempt is made to place one of the at least one crimping tangs into the cup washer opening.

20. A crimping tool operative to crimp a cup washer to a bolt, wherein the bolt includes a head, a plurality of tool engagement surfaces formed on the head and at least one depression formed around a perimeter of the bolt, wherein the cup washer includes a cup for receiving the head of the bolt, a rim disposed around a perimeter of the cup, an opening formed in the cup and the rim, and an anti-rotation tab operative to be disposed in an indentation in an adjacent component when the bolt and the cup washer are installed into the adjacent component, the crimping tool comprising:
a proximal end;
a dis
