Abstract

Disclosed is a system to engage one or more tools. In the system a drive shaft and collet may be assembled to engage and disengage, selectively, a plurality of tools. Further, a tracking device may be used to track a location of at least a portion of the tool.

First claim

What is claimed is:

1. A method of connecting a powered drill assembly to track a tool tip powered by the powered drill, comprising:
connecting a collet assembly having a powered drill motor housing connection configured to fixedly engage a second end of a powered drill motor housing, wherein the powered drill motor housing connection rigidly fixes the collet assembly with the powered drill motor housing;
positioning at least a portion of the collet assembly within a bore formed by an internal surface of an attachment member to at least in part form a first locking feature; and
engaging a secondary locking feature configured to at least limit rotational movement of the attachment member relative to the collet assembly;
wherein a tracking device is fixed relative to an exterior surface of the powered drill motor housing, wherein the tracking device is configured to allow tracking of the powered drill assembly,
wherein engaging the secondary locking feature includes:
moving a protrusion extending from the internal surface of the attachment member past a wave spring positioned on a collet housing; and
releasing the attachment member to allow the wave spring to bias a tab formed on the internal surface of the attachment member into an indent formed in the collet housing.

2. The method of claim 1 , further comprising: tracking the tool tip with the tracking device.

3. The method of claim 2 , further comprising:
eliminating substantial rotation of the tracking device relative to the attachment member at least with the engagement of the secondary locking feature.

4. The method of claim 3 , further comprising:
fixing the tracking device to the exterior surface of the powered drill motor housing.

5. The method of claim 3 , further comprising:
operating a tracking system to track the tool tip.

6. The method of claim 1 , wherein engaging the secondary locking assembly includes:
moving a wedge by rotating a collar of the collet assembly into a first groove formed in the collet housing and into a second groove formed in the internal surface of the attachment member, wherein upon moving the wedge, the wedge is configured to wedge between the internal surface of the attachment member and an external surface of the collet assembly.

7. The method of claim 1 , wherein engaging the secondary locking feature includes moving a rotational locking member into a rotational locking seat.

8. A method of connecting a powered drill assembly to track a tool tip powered by the powered drill, comprising:
connecting a collet assembly having a powered drill motor housing connection configured to operably engage a powered drill motor housing;
positioning at least a portion of the collet assembly within a bore formed by an internal surface of an attachment member to form a first locking feature;
engaging a secondary locking feature configured to limit rotational movement of the attachment member relative to the collet assembly, wherein engaging the secondary feature includes:
moving a wedge by rotating a collar of the collet assembly into a first groove formed in the collet housing and into a second groove formed in the internal surface of the attachment member, wherein upon moving the wedge into the second groove, the wedge biases between the internal surface of the attachment member and an external surface of the collet assembly; and

engaging a tracking device to an exterior surface of the powered drill motor housing, the tracking device configured to allow tracking of the powered drill assembly.

9. A method of connecting a powered drill assembly to track a tool tip powered by the powered drill, comprising:
connecting a collet assembly having a powered drill motor housing connection configured to operably engage a powered drill motor housing;
positioning at least a portion of the collet assembly within a bore formed by an internal surface of an attachment member to form a first locking feature;
engaging a secondary locking feature configured to limit rotational movement of the attachment member relative to the collet assembly, wherein engaging the secondary locking feature includes:
moving a protrusion extending from the internal surface of the attachment member past a wave spring positioned on a collet housing; and
releasing the attachment member to allow the wave spring to bias a tab formed on the internal surface of the attachment member into an indent formed in the collet housing; and

engaging a tracking device to an exterior surface of the powered drill motor housing, the tracking device configured to allow tracking of the powered drill assembly.
