A straightness measurement unit for a cannon barrel is provided to precisely measure straightness and concentricity of the cannon barrel by using a laser measurement unit. A straightness measurement unit for a cannon barrel includes a moving body(100), a bearing-coupled-type handle(200), a laser reflector supporter(300), a reflector(400), and a laser measurement unit. The moving body rotates and slides from side to side inside the barrel. The bearing-coupled-type handle is coupled to an end of the moving body and moves or rotates the moving body. The laser reflector supporter is coupled to the other end of the moving body and supports the reflector. The reflector is coupled to the laser reflector supporter. The laser measurement unit outputs laser to the reflector and detects laser reflected from the reflector for checking straightness of inside of the barrel. |
