The utility model discloses a profile detection device used for a steam turbine blade. The profile detection device comprises a door-shaped supporting rack, and the inner side of the door-shaped supporting rack is, from bottom to top, sequentially provided with a blade root supporting plate, a blade body lower part fixing plate, a plurality of detection clamping plates, a blade body upper part fixing plate, and a blade top supporting plate. The inner side surface of the door-shaped supporting rack above a groove is provided with at least two fixing strip groups which are arranged vertically in pairs. Each fixing strip group is formed by embedding a plurality of fixing strips in the inner side surface of the door-shaped supporting rack sequentially in an end-to-end manner, and the fixing strips are provided with a plurality of supporting protruding blocks. The inner side surface of the door-shaped supporting rack is provided with a plurality of horizontally-arranged supporting strips which are supported by the supporting protruding blocks on the inner side surface of the door-shaped supporting rack, and the supporting strips and the door-shaped supporting rack are fixedly connected together by bolts. The profile detection device is suitable for the steam turbine blade, and can be used to quickly and conveniently detect whether the profile of the blade reaches the standard.
