Abstract

Drill plate assemblies are disclosed in the examples herein. An example method includes positioning an absorbent material between a drill plate and a surface to be drilled; performing a drilling operation on the surface including flowing coolant through the drill; and capturing at least some of coolant in the absorbent material.

First claim

What is claimed is:

1. A method, comprising:
positioning an absorbent material between a drill plate and a surface to be drilled;
performing a drilling operation on the surface including flowing coolant through a drill, wherein prior to performing the drilling operation, the absorbent material is not saturated with coolant; and
capturing at least some of the coolant in the absorbent material during the drilling operation.

2. The method of claim 1 , wherein positioning the absorbent material includes disposing the absorbent material within a housing and coupling the drill plate to the housing.

3. The method of claim 2 , wherein the housing includes a contour corresponding to a contour of the surface.

4. The method of claim 2 , further including positioning a bushing through substantially coaxial apertures of the drill plate and the housing.

5. The method of claim 4 , wherein performing the drilling operation includes coupling a drill to a face of the drill plate or to the bushing.

6. The method of claim 1 , wherein positioning the absorbent material includes coupling the absorbent material and the drill plate to the surface.

7. The method of claim 1 , wherein the surface to be drilled includes a surface of a fuselage, and the positioning of the absorbent material includes coupling the drill plate and the absorbent material to the surface of the fuselage.

8. An apparatus, comprising:
a housing defining a cavity;
an absorbent material to be disposed within the cavity;
a drill plate to be coupled to the housing, the absorbent material to be between the drill plate and a surface to be drilled during a drilling operation, the absorbent material to collect coolant during the drilling operation; and
a bushing extending through the drill plate and the cavity of the housing to enable an end of the bushing to be disposed immediately adjacent the surface to be drilled during the drilling operation.

9. The apparatus of claim 8 , wherein the housing, the absorbent material, and the drill plate define substantially coaxial apertures through which a drill bit is to extend during the drilling operation.

10. An apparatus, comprising:
a housing defining a cavity;
an absorbent material to be disposed within the cavity; and
a drill plate to be coupled to the housing, the absorbent material to be between the drill plate and a surface to be drilled during a drilling operation, the absorbent material to collect coolant during the drilling operation, the housing, the absorbent material, and the drill plate define substantially coaxial apertures through which a drill bit is to extend during the drilling operation, wherein the drilling operation is a first drilling operation and the coaxial apertures are first coaxial apertures, wherein the housing, the absorbent material, and the drill plate define second substantially coaxial apertures through which the drill bit is to extend during a second drilling operation.

11. An apparatus, comprising:
a housing defining a cavity;
an absorbent material to be disposed within the cavity;
a drill plate to be coupled to the housing, the absorbent material to be between the drill plate and a surface to be drilled during a drilling operation, the absorbent material to collect coolant during the drilling operation, wherein the housing, the absorbent material, and the drill plate define substantially coaxial apertures through which a drill bit is to extend during the drilling operation; and
a bushing coupled to the drill plate, the bushing to extend through the coaxial apertures.

12. The apparatus of claim 11 , wherein the bushing is coupled to the drill plate via an interference fit.

13. The apparatus of claim 8 , wherein the surface is a first surface, the housing includes a second surface having a contour that corresponds to a contour of the first surface.

14. An apparatus, comprising:
a bushing through which a drill bit is to extend during a drilling operation, the bushing structured to enable the drill bit to rotate relative to the bushing during the drilling operation; and
an absorbent material surrounding the bushing, the absorbent material to collect coolant during the drilling operation.

15. The apparatus of claim 14 , further including a fuselage, the bushing, and the absorbent material to be coupled to the fuselage to enable the drilling operation to be performed on a surface of the fuselage.

16. The apparatus of claim 14 , wherein the absorbent material defines an aperture through which the bushing extends.

17. The apparatus of claim 14 , further including a housing in which the absorbent material is disposed and through which the bushing extends.

18. The apparatus of claim 17 , wherein a cover of the housing includes a drill plate.

19. The apparatus of claim 17 , wherein the housing includes a contour that corresponds to a contour of a surface to be drilled.

20. The apparatus of claim 17 , wherein the bushing includes a coupling to couple the bushing to a drill during the drilling operation.

21. A method, comprising:
positioning an absorbent material between a drill plate and a surface to be drilled, wherein positioning the absorbent material includes disposing the absorbent material within a housing and coupling the drill plate to the housing;
performing a drilling operation on the surface including flowing coolant through a drill;
capturing at least some of the coolant in the absorbent material; and
enabling coolant to flow out of the absorbent material and through a drain during the drilling operation.

22. The method of claim 1 , wherein flowing coolant through the drill includes flowing coolant through a drill bit used during the drilling operation.
