Abstract

A staking tool includes an assembly having two substantially parallel punch members. The punch members are located partially in a punch body, and the punch body is located adjacent to a lower shaft. The lower shaft has an angled face configured to contact the punch body so that an angle is formed between the punch body and lower shaft. A main shaft is connected to the lower shaft. A cap is connected to the main shaft. A blow applied to the cap transfers force to the punch body, and the angled face redirects the direction of the force by the angle.

First claim

The invention claimed is:

1. A staking tool comprising:
a punch body;
a lower shaft;
an assembly having two substantially parallel punch members, the punch members located partially in the punch body, the punch body located adjacent to the lower shaft, the lower shaft having an angled face configured to contact the punch body so that an angle is formed between the punch body and lower shaft, the angle is about 45 degrees;
a lower body of the assembly, the punch body and the two punch members are located substantially within the lower body;
an upper body of the assembly, the lower shaft located substantially in the upper body;
a main shaft connected to the lower shaft;
a cap connected to the main shaft;
a locator member attached to the lower body, the locator member configured to align the punch members with a twist lock device; and
wherein a blow applied to the cap transfers force to the punch body, and the angled face redirects the direction of the force by the angle.

2. The staking tool of claim 1 , further comprising:
two fasteners;
wherein the locator member has a general U-shape and the locator member has two legs with slots formed therein, the slots configured for use with the fasteners and the slots enabling a position of the locator member to be adjusted as the slots slide relative to the fasteners.

3. The staking tool of claim 1 , the lower shaft comprising a spring configured to contact the lower body, the spring configured to bias the lower shaft away from the punch members.

4. The staking tool of claim 1 , the lower body comprising a shoulder section configured for insertion into a land of a turbomachine's wheel.

5. The staking tool of claim 4 , wherein the lower body and the shoulder section are configured so that the main shaft angles away from the wheel by about 5 degrees to about 15 degrees.

6. The staking tool of claim 1 , wherein the lower body comprises an adjustable stop to set a length of travel of the punch members.

7. A staking tool comprising:
a punch body;
a lower shaft;
an assembly having at least one punch member, the punch member located partially in the punch body, the punch body located adjacent to the lower shaft, the lower shaft having an angled face configured to contact the punch body so that an angle of about 45 degrees is formed between the punch body and lower shaft;
a lower body of the assembly, the punch body and the at least one punch member located substantially within the lower body;
an upper body of the assembly, the lower shaft located substantially in the upper body;
a main shaft connected to the lower shaft;
a locator member attached to the lower body, the locator member configured to align the at least one punch member with a twist lock device;
a cap connected to the main shaft; and
wherein a blow applied to the cap transfers force to the punch body, and the angled face redirects the direction of the force by the angle.

8. The staking tool of claim 7 , further comprising at least two substantially parallel punch members.

9. The staking tool of claim 7 , further comprising at least four punch members.

10. The staking tool of claim 7 further comprising:
fasteners; and
wherein the locator member has a general U-shape and the locator member has two legs with slots formed therein, the slots configured for use with the fasteners and the slots enabling a position of the locator member to be adjusted as the slots slide relative to the fasteners.

11. The staking tool of claim 10 , the lower shaft comprising a spring configured to contact the lower body, the spring configured to bias the lower shaft away from the at least one punch member.

12. The staking tool of claim 11 , the lower body comprising a shoulder section configured for insertion into a land of a turbomachine's wheel.

13. The staking tool of claim 12 , wherein the lower body and the shoulder section are configured so that the main shaft angles away from the wheel by about 5 degrees to about 15 degrees.

14. The staking tool of claim 13 , wherein the lower body comprises an adjustable stop to set the length of travel of the at least one punch member.

15. A staking tool comprising:
an upper body, a shaft located in the upper body;
a lower body, a punch body and at least one punch member located substantially within the lower body, the at least one punch member located partially in the punch body, the punch body located adjacent to the shaft, the shaft having an angled face configured to contact the punch body so that an angle is formed between the punch body and the shaft; and
a locator member attached to the lower body, the locator member configured to align the at least one punch member with a device.

16. The staking tool of claim 15 , further comprising at least two substantially parallel punch members, or at least four punch members.

17. The staking tool of claim 15 , further comprising:
fasteners; and
wherein the locator member has a general U-shape and the locator member has two legs with slots formed therein, the slots configured for use with the fasteners, and the slots enabling a position of the locator member to be adjusted as the slots slide relative to the fasteners.

18. The staking tool of claim 15 , the shaft comprising a spring configured to contact the lower body, the spring configured to bias the shaft away from the at least one punch member.

19. The staking tool of claim 15 , the lower body comprising a shoulder section configured for insertion into a land of a wheel of a turbomachine.

20. The staking tool of claim 19 , wherein the lower body and the shoulder section are configured so that the shaft angles away from the wheel by about 5 degrees to about 15 degrees.

21. The staking tool of claim 15 , wherein the lower body comprises an adjustable stop to set the length of travel of the at least one punch member.

22. The staking tool of claim 15 , the angle being about 45 degrees.
