PURPOSE: A test piece aligning device for generating fatigue preliminary cracks is provided to minimize generation of crack test pieces which fail to meet fatigue preliminary crack generation standards by maximizing the alignment accuracy of test pieces. CONSTITUTION: A test piece aligning device for generating fatigue preliminary cracks includes a main body (110) and a movable member (120). The main body has the lower end part of one side which is equipped with a mounting groove (110a) on which one of rollers are settled, and the other side which is equipped with a guide groove in the length direction. The movable member has the lower end part which is supported by the guide groove, and the upper end part which is inserted into a notch groove. Test pieces are aligned with the notch groove which is supported on the upper end part by settling one roller in the mounting groove and by transferring the movable member along the guide groove. |
