Abstract

The present disclosure relates generally to a tool that facilitates machining of inserts mounted in a primary component. More specifically, tools according to the present disclosure may be designed to support removal of recessed inserts in primary components without damaging the underlying primary components.

First claim

What is claimed is:

1. A tool for facilitating removal of recessed inserts from a primary component, the tool comprising
a tool body including an interface piece with a first side adapted to be placed in contact with an outer surface of the primary component and formed to define an interface-piece aperture sized to allow a machine tool to extend through the interface piece toward a recessed insert assembled within the primary component so that the outer surface of the primary component around the interface-piece aperture is protected from the machine tool when the machine tool is inserted through the interface-piece aperture,
a guide coupled to the tool body along a second side of the interface piece, opposite the first side, the guide formed to include an angled tool-receiver surface that (i) surrounds a guide aperture aligned with the interface-piece aperture, and (ii) that is shaped to slope toward the guide aperture so as to encourage the machine tool moving toward the guide through the guide aperture and the interface-piece aperture; and
a recess plug coupled to the interface piece of the tool body, the recess plug configured to extend away from the first side of the interface piece into a recess that extends inwardly from the outer surface of the primary component, the recess including an annular shoulder defining a stepped interior region defining a first interior diameter axially outward of the annular shoulder and defining a second interior diameter smaller than the first interior diameter axially inward of the annular shoulder, the recessed insert arranged within the interior region having the second interior diameter, and the recess plug arranged within the interior region having the first diameter and resting on the annular shoulder, formed to define a plug aperture aligned with the interface-piece aperture and sized to allow the machine tool to extend through the recess plug toward the recessed insert so that a side surface and the annular shoulder of the primary component that defines that recess is protected from the machine tool when the machine tool is inserted through the plug aperture.

2. The tool of claim 1 , wherein the guide includes a tool receiver and an attachment ring, such that the tool receiver defines the guide aperture and the angled tool-receiver surface, and the attachment ring extends from the tool receiver away from the guide aperture.

3. The tool of claim 1 , wherein the recess plug is formed to include an O-ring receiving feature and an O-ring is located in the O-ring receiving feature, and the O-ring extends around the recess plug in order to engage the side surface when the machine tool is inserted through the plug aperture.

4. The tool of claim 1 , wherein the interface piece includes an interface panel and a plug mount coupled to the interface panel, the interface panel provides a first side surface of the interface piece, and the plug mount is configured to allow a removable attachment of the recess plug to the plug mount.

5. The tool of claim 4 , wherein the plug mount included in the tool body is formed to include mount threads and the recess plug is formed to include plug threads engaged with the mount threads to removably couple the recess plug to the tool body.

6. The tool of claim 1 further comprising a lighting system including a plurality of lights mounted around the interface-piece aperture to illuminate the interface-piece aperture.

7. The tool of claim 6 wherein the lighting system is coupled to an internal power source housed in the tool body.

8. The tool of claim 1 further comprising a vacuum system including at least one vacuum port arranged to open directly into a tool passageway defined, at least in part, by the interface-piece aperture and the plug aperture in order to remove debris generated by the machine tool when used to remove the recessed insert.

9. The tool of claim 8 , wherein the vacuum system includes at least one vacuum duct that extends from the at least one vacuum port through the tool body to carry the debris away from the tool passageway.

10. The tool of claim 9 , wherein the vacuum system includes a vacuum connector coupled to the tool body at a location spaced apart from the at least one vacuum port and coupled fluidly to at least one vacuum duct, the vacuum connector configured to be coupled to an external vacuum source.

11. A tool for facilitating removal of recessed inserts from a primary component, the tool comprising
a tool body including an interface piece with a first side adapted to be placed in contact with an outer surface of the primary component and formed to define an interface-piece aperture sized to allow a machine tool to extend through the interface piece toward a recessed insert assembled within the primary component so that the outer surface of the primary component around the interface-piece aperture is protected from the machine tool when the machine tool is inserted through the interface-piece aperture,
a recess plug coupled to the interface piece of the tool body, the recess plug configured to extend away from the first side of the interface piece into a recess that extends from the outer surface of the primary component, the recess plug formed to define a plug aperture aligned with the interface-piece aperture and sized to allow the machine tool to extend through the recess plug toward the recessed insert so that a side surface of the primary component around the recess is protected from the machine tool when the machine tool is inserted through the plug aperture,
a lighting system including a plurality of lights mounted to the tool body and configured to illuminate the interface-piece aperture so that the machine tool is visible when the machine tool is inserted through the interface-piece aperture, and
a vacuum system, wherein the vacuum system includes at least one vacuum port and a vacuum connector spaced apart from the at least one vacuum port, the at least one vacuum port arranged to open directly into a tool passageway defined by the interface-piece aperture and the plug aperture in order to remove debris generated by the machine tool when used to remove the recessed insert, and the vacuum connector is in fluid communication with the at least one vacuum port and is configured to be coupled to an external vacuum source,
wherein the interface piece of the tool body is formed to include a plurality of light openings arranged around the interface-piece aperture and each of the plurality of lights are arranged in a corresponding light opening, and
wherein the at least one vacuum port is arranged on the same circumferential path around the inner annular face of the interface-piece aperture as the plurality of light openings.

12. The tool of claim 11 , wherein the plurality of lights are spaced apart around a circumference of the interface-piece aperture.

13. The tool of claim 11 , wherein the lighting system includes a battery housed in the tool body and a switch electrically coupled between the plurality of lights and the battery.

14. A tool configured to facilitate removal of recessed inserts from a primary component, the tool comprising
a tool body including an interface piece with a first side adapted to be placed in contact with an outer surface of the primary component and formed to define an interface-piece aperture sized to allow a machine tool to extend through the interface piece toward a recessed insert assembled within the primary component so that the outer surface of the primary component around the interface-piece aperture is protected from the machine tool when the machine tool is inserted through the interface-piece aperture,
