Abstract

The present disclosure provides for improvements in fixturing parts in preparation for an electroplating process, thus reducing part handling. The system provides a reusable masking tool comprising a main body having an opening with a removeable coverplate positioned within the opening and one or more locking tabs engaging a corresponding relief slot in at least one of the sidewalls of the main body. The system also comprises a fastener moveably secured within the main body and extending through a top surface of the main body. The main body, fastener, and coverplate may be fabricated from a polymer material by way of an additive manufacturing process. A shank, fabricated from a conductive material, extends through the fastener and is engaged with the fastener such that upon rotation of the fastener, the shank is drawn into contact with the gas turbine engine component, thus providing a conduit for the electroplating process.

First claim

What is claimed is:

1. A system for securing a gas turbine engine component undergoing an electroplating process comprising:
a main body having a top surface, an opposing bottom surface, a first end with an opening therein, an opposing second end, and a first sidewall and second sidewall spaced between the first end and the second end;
a removeable coverplate positioned within the opening of the first end and having an end plate and one or more mechanisms for securing the coverplate to the main body;
a fastener movably secured within the main body and extending through the top surface of the main body; and
a shank having a first end, an opposing second end and a threaded portion between the first end and the second end;
wherein the shank is engaged with the fastener such that upon rotation of the fastener, the first end of the shank is drawn into contact with the gas turbine engine component positioned in the main body.

2. The system of claim 1 , wherein the main body is fabricated using an additive manufacturing process.

3. The system of claim 2 , wherein the main body is fabricated from a polymer material.

4. The system of claim 3 , wherein the coverplate is fabricated from a polymer material.

5. The system of claim 4 , wherein the one or more mechanisms of the coverplate comprises a plurality of locking tabs for engaging one or more corresponding relief slots in at least one of the first sidewall and the second sidewall.

6. The system of claim 3 , wherein the fastener is fabricated from a polymer material.

7. The system of claim 1 , wherein the main body further comprises a retention slot for securing the gas turbine engine component in the main body at a predetermined orientation.

8. The system of claim 1 , wherein the shank is fabricated from conductive material.

9. The system of claim 1 , wherein the shank further comprises an asymmetric profile proximate the first end of the shank.

10. The system of claim 1 , wherein the fastener further comprises internal thread corresponding to the threaded portion of the shank.

11. A housing for use in masking a portion of a gas turbine engine component during an electroplating process, the housing comprising:
a main body having a top surface, an opposing bottom surface, a first end with an opening therein, an opposing second end, and a first sidewall and second sidewall spaced between the first end and the second end, the first sidewall and second sidewall each having a relief slot;
a removeable coverplate positioned within the opening of the first end and having an end plate and a plurality of locking tabs for engaging the relief slots of the first sidewall and second sidewall; and
a fastener having a portion located within the main body and extending through the top surface of the main body, the fastener positioned such that it is free to rotate relative to the main body.

12. The housing of claim 11 , wherein the housing is fabricated using an additive manufacturing process.

13. The housing of claim 12 , wherein the housing is fabricated from a polymer material.

14. The housing of claim 12 , wherein the fastener further comprises a cylindrical opening at one end thereof with the cylindrical opening having a plurality of internal threads.

15. The housing of claim 11 further comprising a retention slot in the bottom surface configured to hold the gas turbine engine component within the housing.

16. The housing of claim 11 , wherein the removeable coverplate further comprises a pull tab extending away from the endplate, opposite from the plurality of locking tabs.

17. A system of a plurality of gas turbine components fixtured for an electroplating process comprising:
a support bar;
a plurality of mounting fixtures coupled to the support bar;
a plurality of securing systems for securing the plurality of gas turbine components undergoing the electroplating process, each of the plurality of securing systems coupled to one of the plurality of mounting fixtures and comprising:
(1) a main body having a top surface, an opposing bottom surface, a first end with an opening therein, an opposing second end, and a first sidewall and second sidewall spaced between the first end and the second end, at least one of the first sidewall and second sidewall having a relief slot;
(2) a removeable coverplate positioned within the opening of the first end and having an end plate and one or more locking tabs for engaging a corresponding relief slot in at least one of the first sidewall and the second sidewall;
(3) a fastener movably secured within the main body and extending through the top surface of the main body; and
(4) a shank having a first end, an opposing second end having an asymmetric profile, a threaded portion between the first end and the second end, and a notch located proximate the second end;

wherein the shank is engaged with the fastener and main body such that the asymmetric profile and notch of the shank permit controlled attachment and manipulation of the system for application of maskant to the gas turbine engine component once installed within a mounting fixture.

18. The system of claim 17 , wherein the application of maskant comprises an ultraviolet cured maskant.

19. The system of claim 18 , wherein the maskant is applied by an automated process.
