According to an embodiment of the present invention, an apparatus for adjusting concentricity comprises a main body unit which is combined to a rotary shaft of an object to be tested; and a light emitting unit which is placed inside the main body unit in order to emit light with a linear property to the outside. The main body unit and the light emitting unit are combined to each other in order to have the same central axis as the rotary shaft. The light emitting unit emits the light in a longitudinal direction of the rotary shaft. The apparatus for adjusting concentricity is placed at the fore-end of the rotary shaft in order to emit light without an additional gauge for adjusting the incline of the rotary shaft. Therefore, the apparatus for adjusting concentricity can be easily and conveniently installed compared with the gauge, and can improve work efficiency and productivity through rapid work progress by identifying the track of light through the rotation of the rotary shaft and adjusting the angle of an object to be tested and the rotary shaft. |
