Abstract

Vibratory treatment apparatus including a first receptacle arranged to receive media for vibratory treatment of the article, the first receptacle defining a first aperture; and a first valve positioned at the first aperture of the first receptacle, the first valve being arranged to allow passage of the article there through and to prevent the flow of media through the first aperture.

First claim

What is claimed is:

1. Vibratory treatment apparatus comprising:
a first receptacle defining a cavity having an opening arranged to receive vibratory media for vibratory treatment of an article, the first receptacle defining a first aperture opposite the opening of the cavity; and
a first valve positioned at the first aperture of the first receptacle, the first valve being arranged to allow passage of the article there through and to prevent the flow of the vibratory media through the first aperture.

2. Vibratory treatment apparatus as claimed in claim 1 , further comprising a second receptacle arranged to receive the first receptacle therein, the first receptacle having a first depth and the second receptacle having a second depth, the first depth being less than the second depth.

3. Vibratory treatment apparatus as claimed in claim 2 , wherein the first receptacle is coupled to the second receptacle via one or more fasteners.

4. Vibratory treatment apparatus as claimed in claim 2 , wherein a width of the first receptacle is less than a width of the second receptacle.

5. Vibratory treatment apparatus as claimed in claim 2 , wherein a length of the first receptacle is less than a length of the second receptacle.

6. Vibratory treatment apparatus as claimed in claim 1 , further comprising a fixture arranged to support an article for receiving vibratory treatment; and a first actuator arranged to move the fixture relative to the first receptacle.

7. Vibratory treatment apparatus as claimed in claim 6 , wherein the fixture is arranged to support a plurality of articles for receiving vibratory treatment.

8. Vibratory treatment apparatus as claimed in claim 1 , further comprising a second actuator arranged to move the first receptacle to vibrate the media relative to the first receptacle.

9. Vibratory treatment apparatus as claimed in claim 1 , wherein the first receptacle defines a second aperture, and the apparatus further comprises a second valve positioned at the second aperture of the first receptacle, the second valve being arranged to allow passage of another article there through and to prevent flow of the media through the second aperture.

10. Vibratory treatment apparatus as claimed in claim 1 , wherein the media is vibratory polishing media.

11. Vibratory treatment apparatus as claimed in claim 1 , wherein the media is vibratory peening media.

12. Vibratory treatment apparatus as claimed in claim 1 , wherein the article is a fan blade of a gas turbine engine.

13. A method of vibratory treating an article, the method comprising:
providing a vibratory treatment apparatus, the vibratory treatment apparatus comprising:
a first receptacle defining a cavity having an opening arranged to receive vibratory media for vibratory treatment of an article, the first receptacle defining a first aperture opposite the opening of the cavity; and
a first valve positioned at the first aperture of the first receptacle, the first valve being arranged to allow passage of the article there through and to prevent the flow of the vibratory media through the first aperture; and

controlling movement of the article relative to the first receptacle and through the first aperture of the first receptacle.

14. A method as claimed in claim 13 , wherein the method further comprises:
controlling a second actuator to move the first receptacle to vibrate the media relative to the first receptacle.
