DEVICE DESIGNED FOR CLAMPING A TURBINE BLADE AND TURBINE BLADE

摘要

The invention relates to a device designed for clamping a turbine blade (6) comprising a clamping unit (5), which has at least two clamping block parts (31, 32) which form a clamping block (3) and which enclose the turbine blade (6) with a blade shell (7) which is formed from a plastic shell layer which remains substantially dimensionally stable under clamping force. The blade shell (7) receives the vane (61) in positive engagement and can be separated from the blade (61). On the concave underside (611) of the blade and on the convex upper face (612) of the blade the plastic shell layer has outwardly exposed male surfaces (8) which are each defined by a three-dimensionally structured male profile (81) forming a relief. The clamping block parts (31, 32) each have a female surface (4) on an inner face, wherein said female surface is defined by a three-dimensionally structured female profile (41) forming a relief. The male surfaces (8) and the female surfaces (4) are formed as associated complementary surfaces which correspond to one another and form a reference and clamping engagement. A turbine blade (6) which is provided with said blade shell (7) forms a part for insertion between the clamping block parts (31, 32).
