Described magnet steel holder is provided with at least one fixedly second fastening bolt of magnet steel.
Compared with prior art, the beneficial effect that the utility model reached is as follows:
1, because the magnet steel assembly tool that the utility model adopts fixed head, handwheel, screw mandrel, guide post, base, magnet steel holder and adjusting screw(rod) to form, rotate handwheel, can drive the magnet steel holder moves being parallel to rotor cylinder axial direction, and by reversing adjusting screw(rod), can realize that the magnet steel holder is moving perpendicular to the rotor axial direction, thereby when assembling, can adjust, magnet steel is assembled on the position that needs assembling exactly the magnet steel rigging position; And because when assembling, magnet steel is fixed in the magnet steel holder, thereby overcome the strong magnetic adsorbability of magnet steel to rotor core, avoid having an accident, the utility model is particularly useful for as the assembly tool that partly directly drives megawatt-level permanent magnet wind-driven generator surface magnet steel, and also is applicable to the installation and removal when magnet steel adopts oblique electrode structure.
2, in the utility model, screw mandrel and guide post be arranged in parallel, help the smooth guiding of base more and adjust the shift position of base by handwheel.
3, in the utility model, screw mandrel and guide post all are installed on a side of fixed head, be provided with at least one first fastening bolt at opposite side, such frame mode, help vacateing the suitable distance between magnet steel holder and the rotor, be convenient to adjust the displacement of magnet steel holder, also make the two ends that are clamped in rotor that fixed head can be more firm.
3, in the utility model, adjusting screw(rod) is four, can make the magnet steel holder more reposefully along moving perpendicular to the rotor axial direction, and rigging position is more accurate.
4, in the utility model, the magnet steel holder is provided with at least one fixedly second fastening bolt of magnet steel, can guarantee further that magnet steel is fixed in the magnet steel holder, can not have an accident.
