The invention relates to the field of wind turbines, and discloses a positioning tool assembly. The positioning tool assembly comprises a lineation tool and a punching tool; the lineation tool comprises two positioning columns arranged in parallel, a first positioning beam and a second positioning beam are connected between the two positioning columns, and a polishing area is defined by the firstpositioning beam, the second positioning beam and the two positioning columns; and the punching tool comprises a positioning plate, a plurality of limiting through holes are formed in the positioningplate, a lifting mechanism is installed at the bottom of the positioning plate, a positioning rod is installed on the positioning plate, and the length of the positioning rod is matched with the distance between every two adjacent oil injection holes. The polishing area and a drilling area on the surface of an inner ring of a main bearing of a permanent magnet generator can be effectively positioned, so that polishing and
