Problems solved by technology
[0003] 1. Due to the extremely strong magnetism of the magnetic steel, life safety accidents are prone to occur;
[0004] 2. Due to the extremely strong magnetic force, it is extremely difficult to put the rotor into the inner hole of the stator or pull the rotor out of the inner hole of the stator by manpower.

Embodiment Construction
[0018] See figure 1 , A permanent magnet generator stator and rotor composite tooling structure 100. The rotor 200 includes a rotating shaft 1, a bearing 2, a magnetic steel 12 and a yoke 3 sleeved on the rear end of the rotating shaft 1; the yoke 3 The distance between the rear end surface of and the rear end surface of the bearing 2 is d1; the distance between the rear end surface of the yoke 3 and the front end surface of the bearing 2 is d2.
[0019] See again figure 2 , image 3 with Figure 4 The synthetic tooling structure 100 includes a positioning ring 4, a bottom plate 5, a core rod 6, two semicircular sleeves 7, a bracket 8 and a hydraulic cylinder 9 fixed on the bracket 8; the outer wall of the positioning ring 4 There is a flat cut surface 42 which is welded to the bottom plate 5. The central axis of the positioning ring 4 has a stepped through hole 41; the maximum inner diameter m of the through hole 41 is greater than the outer diameter of the stator 300 by 0.2~ 0...

Provided is a combined tool structure of a stator and a rotor of a permanent magnet generator. The rotor comprises a rotating shaft, a bearing and magnetic steel. The combined tool structure comprises a locating ring, a bottom plate, a core rod and two semicircle sleeves. The outer wall of the locating ring is provided with a sliced plane, the sliced plane is welded with the bottom plate, and a step-shaped through hole is arranged in the center shaft position of the locating ring. The maximum inner diameter of the through hole is equal to or larger than the outer diameter of the stator by 0.2-0.5mm, and the minimum inner diameter of the through hole is larger than the maximum outer diameter of a generator fan. The outer diameter of the core rod is smaller than the center hole of the stator and larger than the outer diameter of the magnetic steel, and one end face, corresponding to the center shaft position, of the core rod is hollowed inwards to form a counter bore matched with the bearing. The outer diameter of each semicircle sleeve is the same as the inner diameter of the counter bore, and the rear end of the rotating shaft can penetrate through the circle formed by enclosure of the two semicircle sleeves. The combined tool structure has the advantages of being simple in structure, convenient to operate, safe and reliable, high in assembly efficiency and the like.
Description
【Technical Field】 [0001] The invention specifically relates to a composite tooling structure of a stator and a rotor of a permanent magnet generator. 【Background technique】 [0002] The rotor of rare earth permanent magnet generator is mainly composed of shaft, yoke, magnetic steel, fan, bearing and other components (such as figure 1 Shown); The stator is mainly composed of iron core and armature windings (such as figure 2 Shown). Because the magnetic steel is made of high-magnetic rare earth permanent magnet (NdFeB) material, its magnetism is very strong. When it is close to the magnetic material such as iron, the attractive force generated is great, and the stator core material is silicon steel sheet, which is high Magnetically conductive material, so manually inserting the rotor into the inner hole of the stator or pulling the rotor out of the inner hole of the stator will have the following disadvantages: [0003] 1. Due to the strong magnetism of magnetic steel, life safety ...
