摘要

A device to measure the critical dimension of 3 DS and FZ shroud blade of steam turbine comprising : a fixed column (01) erected vertically on base (6); a guide way (7) on base (6); a moveable vertical sliding column (2) disposed such that it can slide on the guide way (7) forward and backward; a fixed male centre (8) disposed on fixed column (01) and sliding male centre (09) disposed on sliding column (2) such that the pointed male centres (04, 04) are horizontal and parallel to the base (6) a work piece adopter (03) with a support (05) for resting of blade (10) disposed on the fixed column characterized in that the male centres tips (04, 04) fit into the centre holes of the F Z-shroud blade horizontally where the fixed male centre (8) and sliding male centre (09) grips the blade properly and horizontally by to and fro movement of the sliding male centre (09) on adjustable sliding column (2).
