Abstract:
A fixture used with a turbine component having a component longitudinal axis and comprising a root having a root surface including a first pair of first pressure surfaces on either side of the component longitudinal axis and oriented at a first angle to the component longitudinal axis, a second pair of second pressure surfaces on either side of the component longitudinal axis and oriented at a second angle to the component longitudinal axis, and a tang at an end of the root, the fixture comprisinga base; a stop affixed to the base and which prevents the turbine component from moving past a stop limit when the turbine component is forced in a clamping direction parallel to the component longitudinal axis; two clamp arms, a first clamp arm being on a leading-edge side of the turbine component with a first clamp surface facing the turbine component, and a second clamp arm being on a trailing-edge side of the turbine component with a second clamp surface facing the turbine component, each clamp arm being movable between a released position in which its clamp surface does not contact one of the pressure surfaces and a clamped position in which its clamp surface contacts one of the pressure surfaces and forces the turbine component in the clamping direction and against the stop; and a clamping force source that controllably moves each of the clamp arms between the released position and the clamped position.
