It should be noted that various modifications can be made to the embodiments disclosed herein, and therefore, the embodiments disclosed in the specification should not be construed as limiting the present invention, but merely as exemplifications of embodiments thereof, which are intended to make the features of the present invention obvious.
As shown in fig. 1, the apparatus for assembling an outer rotor permanent magnet motor disclosed by the present invention includes a base 1, a top plate 2, at least two screws 3, and at least two positioning rods 4. Two screw rods 3 symmetrically penetrate between the base 1 and the top plate 2, a nut is sleeved on each screw rod penetrating through the back face and the front face of the top plate 2, and the height between the top plate 2 and the base 1 is adjusted by adjusting the position of the nut sleeved on the screw rods 3. Two positioning rods 4 symmetrically penetrate between the base 1 and the top plate 2.
When the rotor assembly 5 and the stator assembly 6 of the permanent magnet motor are assembled, the stator assembly 6 is fixed on the base 1 through bolts, and then the rotor assembly 5 is fixed on the top plate 2 through bolts; then, fixing the screw rod 3 and the positioning rod 4 on the base 1; a nut 7 is sleeved at the top of the screw rod 3; then, a positioning rod 4 and a screw 3 sleeved with a nut 7 penetrate through a top plate 2 fixed with a rotor assembly 5; a nut 7 is sleeved at the top of the screw rod 3 penetrating through the top plate 2; finally, the height of the top plate 2, namely the distance between the rotor assembly 5 and the stator assembly 6, is adjusted by adjusting two nuts 7 which are sleeved on the screw rod 3 and are positioned on the back surface and the front surface of the top plate 2, so that the rotor assembly 5 is gradually close to the stator assembly 6, and the assembly of the stator assembly 6 and the rotor assembly 5 of the permanent magnet motor is completed.
Fig. 2 is a structural diagram of the base, and as shown in the figure, a stator positioning hole 11 for fastening the stator assembly 6 is formed in the center of the base 1, and the diameter of the stator positioning hole 11 matches with the installation size of the stator assembly 6. During assembly, the stator assembly 6 is embedded in the stator positioning hole 11, and then the stator assembly 6 is fixed on the base 1 through bolts. At the outer edge of the base 1, at least two threaded holes 12 for penetrating the screw rods 3 are symmetrically arranged, and the threaded holes 12 have a certain depth and are in transition fit with the screw rods 3. At least two counter bores 13 for penetrating the positioning rod 4 are symmetrically arranged at the outer edge of the base 1, and the counter bores 13 have a certain depth and are in transition fit with the positioning rod 4.
In order to ensure that the base 1 fixed with the stator assembly 6 is stable, the threaded holes 12 and the counter bores 13 are uniformly arranged on the same circumference of the outer edge of the base 1 at equal intervals.
Fig. 3 is a schematic structural diagram of the top plate constituting the present invention, and as shown in the figure, a rotor positioning hole 21 for fastening the rotor assembly 5 is formed in the center of the top plate 2, and the diameter of the rotor positioning hole 21 matches with the installation size of the rotor assembly 5. During the assembly, embed rotor subassembly 5 in rotor locating piece 21, then, fix rotor subassembly 5 on roof 2 through the bolt. Through holes 22 are opened on the outer edge of the top plate 2 corresponding to the threaded holes 12 and the counter bores 13 on the base. Through-hole 22 and 3 clearance fit of screw rod, through-hole 22 and locating lever 4 transition fit for screw rod 3 and locating lever 4 can freely wear to establish roof 2 along axial direction.
When assembling an outer rotor permanent magnet motor, 1, firstly, a stator assembly 6 is installed and fixed on a base 1, and a rotor assembly 5 is installed and fixed on a top plate 2; 2. then, the positioning rods 4 and the screw rods 3 are correspondingly arranged in the counter bores 13 and the threaded holes 12 on the base 1 in a penetrating manner; 3. a nut 7 is sleeved on each of the two screws 3; 4. the four through holes 22 on the top plate 2 fixed with the rotor component 5 are penetrated into the positioning rods 4 and the screw rods 3; 5. finally, a nut 7 is sleeved on the top of each screw rod 3. Because the locating rod 4 is in transition fit with the counter bore 13 of the base and the through hole 22 of the top plate, the plane of the top plate 2 and the plane of the base 1 can be kept parallel, thereby ensuring that the stator assembly and the rotor assembly are aligned in the assembling process.
