Abstract

A staking tool is disclosed. The staking tool may include a main body, at least one punch disposed within the main body, and an actuator in mechanical communication with the at least one punch. The actuator may be configured to drive the at least one punch from a first position to a second position.

First claim

1 . A staking tool, comprising:
a main body; at least one punch disposed within the main body; and an actuator in pneumatic communication with the at least one punch, wherein the actuator is configured to drive the at least one punch from a first position to a second position.

2 . The tool of claim 1 , further comprising a shaft movably disposed within the main body.

3 . The tool of claim 2 , wherein the at least one punch is disposed within at least one aperture.

4 . The tool of claim 3 , wherein the at least one punch is replaceable within the at least one aperture.

5 . The tool of claim 2 , wherein the shaft is disposed within a cavity in the main body.

6 . The tool of claim 5 , wherein the cavity comprises an opening.

7 . The tool of claim 5 , wherein the cavity comprises a step configured to limit movement of the shaft.

8 . The tool of claim 7 , wherein the shaft comprises a lip configured to engage the step to limit movement of the shaft.

9 . The tool of claim 5 , further comprising a spring disposed about the shaft within the cavity, wherein the spring is configured to biase the shaft in the first position.

10 . The tool of claim 5 , wherein an end of the shaft is shaped to prevent rotation of the shaft within the cavity.

11 . The tool of claim 1 , wherein actuator comprises a hydraulic cylinder.

12 . A staking tool, comprising:
a main body comprising a cavity; a shaft movably disposed within the cavity, wherein the shaft comprises at least one aperture; at least one punch disposed within the at least one aperture; and an actuator in pneumatic communication with the shaft, wherein the actuator is configured to drive the shaft from a first position to a second position.

13 . The tool of claim 12 , wherein the at least one punch is replaceable within the at least one aperture.

14 . The tool of claim 12 , wherein the cavity comprises an opening.

15 . The tool of claim 14 , wherein the at least one punch extends through the opening when the shaft is in the second position.

16 . The tool of claim 12 , wherein the cavity comprises a step configured to limit movement of the shaft.

17 . The tool of claim 16 , wherein the shaft comprises a lip configured to engage the step to limit movement of the shaft.

18 . The tool of claim 12 , further comprising a spring disposed about the shaft within the cavity, wherein the spring is configured to bias the shaft in the first position.

19 . The tool of claim 12 , wherein an end of the shaft is shaped to prevent rotation of the shaft within the cavity.

20 . (canceled)

21 . The tool of claim 5 , wherein the body further comprises an L-shaped protrusion, the L-shaped protrusion leveraging the tool to provide a counter force as the at least one punch moves between the first position and the second position.
