PURPOSE: A photographing device for device for inspecting a surface of a central hole of a turbine rotor is provided to inspect a surface of a central hole of a turbine rotor with images photographed by a camera by unaided eyes, thereby preventing the distortion of images caused by distance variations. CONSTITUTION: A photographing device for device for inspecting a surface of a central hole of a turbine rotor comprises a camera body(100), a vertical frame(200), a main frame(400), and a link bar(500). The camera body is installed in order to photograph a direction perpendicular to an axis of a central hole, thereby photographing a surface of the central hole of the turbine rotor. The camera body comprises a photographing camera and LED modules. The vertical frame fixes the camera body. The main frame is connected to the vertical frame. One side of the link bar is joined to the main frame and the other side of the link bar is connected to a conveying device capable of moving back and forth. |
