The invention discloses a positioning method for correspondence of non-pulling wheel lathe coordinates to wheels. A lathe, X-direction and Z-direction coordinates located on the lathe and a machiningwheel pair composed of the left wheel, the right wheel and a connecting shaft are included. The positioning method is characterized in that the method comprises the following steps that A, the line parallel to the inner side faces of the wheel edges serves as the X-direction coordinates of the machining wheel pair; parallel or coinciding positioning is correspondingly conducted on the X-directioncoordinates of the machining wheel pair and the X-direction coordinates of the lathe; B, the line perpendicular to the inner side faces of the wheel edges serves as the Z-direction coordinates of themachining wheel pair, and parallel or coinciding positioning is correspondingly conducted on the Z-direction coordinates of the machining wheel pair and the Z-direction coordinates of the lathe. The positioning method solves the problem about positioning of the non-pulling wheel lathe and the machining wheel pair, and the positioning technology is advanced and is initiated at home and abroad.
