Abstract

Vibratory finishing apparatus comprising: a receptacle to receive media; a first fixture to: support an object within the receptacle; and move the object relative to the receptacle in at least a first direction; and a first guide to move relative to the receptacle to direct movement of the media within the receptacle to a predetermined part of the object.

First claim

What is claimed is:

1. Vibratory finishing apparatus comprising:
a receptacle to receive abrasive media that is moved or vibrated within the receptacle, the receptacle including a sidewall;
a first fixture to support an object within the receptacle and move the object relative to the receptacle in at least a first direction; and
a first guide positioned in the receptacle and connected to the sidewall, the first guide being pivotable, relative to the receptacle to rotate between static orientations, about an axis that extends in a vertical direction along the sidewall when the vibratory apparatus is in use, the first guide configured to direct the media moved within the receptacle toward a predetermined part of the object while the first guide is being held in one of the static orientations.

2. Vibratory finishing apparatus as claimed in claim 1 , wherein the first fixture is arranged to move the object relative to the receptacle in at least the first direction by rotating the object.

3. Vibratory finishing apparatus as claimed in claim 1 , wherein the first fixture is arranged to move the object relative to the receptacle in a second direction, different to the first direction.

4. Vibratory finishing apparatus as claimed in claim 3 , wherein the first fixture is arranged to move the object relative to the receptacle in the second direction by rotating the object.

5. Vibratory finishing apparatus as claimed in claim 1 , wherein the first fixture comprises a first fastener to fasten the first fixture to the receptacle.

6. Vibratory finishing apparatus as claimed in claim 1 , wherein the first fixture comprises a second fastener to fasten the object to the first fixture.

7. Vibratory finishing apparatus as claimed in claim 1 , further comprising a first divider separate from and insertable into the receptacle and configured to be positioned within the receptacle, extending across the receptacle and abutting the receptacle at each end of the first divider to separate the abrasive media received in the receptacle.

8. Vibratory finishing apparatus as claimed in claim 7 , wherein the first divider comprises a fastener to fasten the first divider to the receptacle.

9. Vibratory finishing apparatus as claimed in claim 1 , further comprising:
a second fixture to support a further object within the receptacle and move the further object relative to the receptacle in at least a second direction; and
a second guide movable between static orientations, the second guide configured to direct the media moved within the receptacle toward a predetermined part of the further object while the second guide is being held in one of the static orientations.

10. Vibratory finishing apparatus as claimed in claim 1 , wherein the object comprises a fan blade root, or a nozzle guide vane, or a component manufactured by three dimensional additive manufacturing.

11. A method of treating an object, the method comprising:
providing vibratory finishing apparatus as claimed in claim 1 ;
coupling an object to the first fixture of the vibratory finishing apparatus;
moving at least one of the first fixture and the first guide relative to the receptacle;
providing abrasive media to the receptacle of the vibratory finishing apparatus; and
activating a vibration generator of the vibratory finishing apparatus to vibrate the receptacle and cause the abrasive media to rub against the object.

12. The vibratory finishing apparatus as claimed in claim 1 , wherein the axis is adjacent to an end of the first guide at a joint that connects a side of the first guide to the side wall.

13. The vibratory finishing apparatus as claimed in claim 1 , wherein the first guide includes:
a frame secured to and extending along the sidewall;
a guider plate to direct the media moved within the receptacle toward a predetermined part of the object; and
a joint connecting a side of the guider plate to the frame, the joint configured such that the guider plate is rotatable about an axis at the joint, the axis extending along the frame.

14. Vibratory finishing apparatus comprising:
a receptacle to receive abrasive media;
a divider configured to be positioned within the receptacle, the divider extending across the receptacle and abutting the receptacle at each end of the divider;
a first fixture to support an object within a portion of the receptacle defined in part by the divider and move the object relative to the receptacle in at least a first direction; and
a first guide positioned in the portion of the receptacle and is connected at least to the divider and is arranged to rotate relative to the divider about an axis that extends in a vertical direction along the divider when the vibratory apparatus is in use, the first guide being movable relative to the receptacle between static orientations, the first guide configured to direct the media moved within the receptacle toward a predetermined part of the object while the first guide is being held in one of the static orientations.

15. The vibratory finishing apparatus as claimed in claim 14 , wherein the divider includes a u-shaped frame configured to support the weight of a body of the divider and to fasten the divider to the receptacle.

16. The vibratory finishing apparatus as claimed in claim 14 , wherein the first guide includes:
a frame secured to and extending along the divider;
a guider plate to direct the media moved within the receptacle toward a predetermined part of the object; and
a joint connecting a side of the guider plate to the frame, the joint configured such that the guider plate is rotatable about an axis at the joint, the axis extending along the frame.

17. The vibratory finishing apparatus as claimed in claim 14 , wherein the divider is separate from and insertable into the receptacle and the divider is configured to separate the abrasive media received in the receptacle.
