Abstract
A mechanism for removing particulate material from the passages through an article or the cavities in an article such as a turbine blade or vane or other mechanical part that involves vibrating the part while simultaneously blowing air through the part with the part so supported as to cause no bending stresses within the part.
Claims4
Apparatus for removing particulate material from internal passages in an article such as a turbine blade or vane, said article having a root at one end and a tip at the other end, said apparatus including supporting means for the article having a recess to receive the tip of the article;
- means for releasably clamping the supporting means on said article;
- means for supplying air under pressure to said supporting means and thence through the passages in said article;
- means for suspending said supporting means and article for relatively free movement;
- opposed anvils in spaced relation to one another to engage opposite sides of the root;
- and
- means for imparting a vibratory movement to one of said anvils to vibrate the article, said supporting means being laterally offset from and substantially at right angles to the axis of the vibratory movement of the anvil and being flexibly held in position such that the vibratory movement is substantially at right angles to the passages in the article.
