[0024] Embodiment 1

[0025] Please refer to Figures 1-4 As shown, an external rotor permanent magnet pasting tooling includes a bottom plate 1;

[0026] A rotating base 2 is arranged on the top of the bottom plate 1. A central axis 4 is rotatably connected to the inside of the rotating base 2 through a bearing 9. A rotating disk 3 is arranged on the lower surface inside the rotating base 2. A plurality of uniformly distributed mounting holes 6 are formed in the top of the rotating disk 3. The rotating disk 3 and the central axis 4 are installed through a snap ring 8. Mounting assemblies 5 are arranged between the rotating disk 3 and the rotating base 2 and between the central axis 4 and the bottom plate 1. A limiting assembly 7 is arranged between the rotating base 2 and the bottom plate 1. During operation, the rotating disk 3 is installed between the rotating base 2 through the mounting assembly 5, and the bottom plate 1 is installed between the central axis 4 through the mounting assembly 5. The mounting assembly 5 facilitates the assembly and disassembly of the tooling. Then, mounting holes 6 for fixing the rotor are formed in the top of the rotating disk 3, and are connected to the external rotor through external bolts to realize the stable rotation of the external rotor. Therefore, the external permanent magnet is pasted through this tooling. At the same time, during rotation, the rotating disk 3 and the rotating base 2 and the external installation equipment rotate through the bearing 9 and the snap ring 8, and the rotation between the rotating base 2 and the bottom plate 1 is stabilized through the limiting assembly 7, and the use effect of the tooling is better.

[0027] The bottom of the rotating base 2 is attached to the top of the bottom plate 1; during operation, the rotating base 2 can be separated and disassembled from the bottom plate 1.

[0028] The bottom of the rotating disk 3 is attached to the lower surface inside the rotating base 2; during operation, the rotating disk 3 can be separated and disassembled from the rotating base 2.

[0029] The installation component 5 includes a plurality of uniformly distributed threaded holes 501 formed at the bottom of the central shaft 4 and the inner lower surface of the rotating base 2. A plurality of uniformly distributed through holes 503 are formed inside both the bottom plate 1 and the rotating disc 3. An installation bolt 502 passes through the through hole 503, and the installation bolt 502 is threadedly connected to the threaded hole 501. During operation, the rotating disc 3 and the rotating base 2 are installed by threading the installation bolt 502 passing through the through hole 503 with the threaded hole 501. At the same time, it is also convenient for the bottom plate 1 and the rotating base 2 to be installed, and it is also convenient for disassembly. When disassembling, the installation bolt 502 is turned away.

[0030] The limiting component 7 includes a continuous limiting groove 701 formed at the bottom of the rotating base 2. A plurality of uniformly distributed limiting rods 702 are movably connected inside the limiting groove 701, and the bottom ends of the limiting rods 702 are fixedly connected to the top of the bottom plate 1. A continuous clamping groove 703 is formed on the left and right sides inside the limiting groove 701. A through groove 705 is formed through the limiting rod 702. Two clamping blocks 704 are slidably connected inside the through groove 705. A spring 706 is fixedly connected between the two clamping blocks 704. During operation, the rotation of the rotating base 2 on the top of the bottom plate 1 is limited by the movable connection between the limiting rod 702 and the limiting groove 701 and the movable connection between the clamping block 704 and the clamping groove 703, and the rotation of the rotating base 2 is relatively stable. When the rotating base 2 is moved and disassembled, the clamping block 704 inside the clamping groove 703 is squeezed, and the spring 706 is contracted by the extrusion, so as not to affect the disassembly and installation of the rotating base 2. When in use, the clamping block 704 is inserted stably inside the clamping groove 703, and the limiting effect is better.

[0031] The clamping block 704 is clamped inside the clamping groove 703 and is movably connected to the clamping groove 703. During operation, the clamping block 704 can rotate and move inside the clamping groove 703, and the clamping block 704 can be clamped inside the clamping groove 703.
