Abstract
A turbine blade holding device is disclosed for accurately holding a turbine blade relative to its stacking axis during grinding of the root form portion thereof. The device includes a fixed base and front and rear datum plates for supporting spaced sections of the air foil portion of the blade. A longitudinally extending pin is connected with the base and is designed to abut against the datum point of the blade. A clamping mechanism clamps the blade against the pin and the datum plates, with the front datum plate supporting the leading and trailing edges of the blade and the rear datum plate supporting the leading edge of the blade. The clamping mechanism includes an elongated clamp pivotally connected with the base and arranged along the fulcrum of the blade.
Claims18
