Referring to fig. 1 to fig. 3 together, a description is now given of a flywheel assembly jig according to an embodiment of the present application, where the flywheel assembly jig includes an assembly mechanism 100 and a pressing mechanism 200, the assembly mechanism 100 is provided with an accommodating slot 111 capable of accommodating a flywheel 400, the assembly mechanism 100 is further provided with a plurality of positioning magnets 113 and a plurality of limiting posts 112, the plurality of limiting posts 112 are disposed in the accommodating slot 111 at intervals, a limiting slot 117 capable of limiting an assembly magnet 500 is formed between two adjacent limiting posts 112, each limiting slot 117 corresponds to a position of one positioning magnet 113, and the positioning magnet 113 is suitable for being attracted to a corresponding assembly magnet 500. The pressing mechanism 200 can abut against the assembling mechanism 100 or the flywheel 400 to press the assembling magnet 500 in the flywheel 400.

Referring to fig. 4, in the present application, each halbach array magnet has a plurality of assembly magnets 500, specifically, the assembly magnets 500 include 4 first magnets 510 and 4 second magnets 520, and the first magnets 510 and the second magnets 520 are alternately arranged in a circumferential direction, wherein a magnetizing direction of the first magnets 510 is a horizontal direction, a magnetizing direction of the second magnets 520 is an axial direction, and magnetizing directions of two adjacent first magnets 510 are opposite to each other and magnetizing directions of two adjacent second magnets 520 are also opposite to each other.

Referring to fig. 5, the flywheel 400 has a first annular assembly groove 411 and a second annular assembly groove 412 symmetrically disposed on opposite sides thereof, and the first annular assembly groove 411 and the second annular assembly groove 412 are respectively used for assembling halbach array magnets having the same shape and width as the assembly groove 410.

It can be understood that the receiving grooves 111 are disposed on the assembly mechanism 100, so that when the assembly magnets 500 are pressed into the assembly grooves 410 on the flywheel 400, the flywheel 400 can be better positioned on the assembly mechanism 100.

Referring to fig. 3, the positioning magnet 113 is disposed on the mounting mechanism 100, and it should be understood that the positioning magnet 113 has a magnetic property opposite to that of the magnet 500 to be mounted, so as to generate an attractive magnetic force on the mounting magnet 500. Thus, after the positioning magnet 113 is assembled in the assembly mechanism 100, an adsorption position is formed in a projection area of the positioning magnet 113 on the bottom of the accommodating groove 111 of the assembly mechanism 100, and after the assembly magnet 500 is placed on the accommodating groove 111, the adsorption position is attracted by the magnetic force generated by the positioning magnet 113, so that the pre-positioning effect is achieved.

Referring to fig. 3, the positioning magnets 113 are disposed on the assembly mechanism 100 at intervals in a circumferential array, such that the accommodating slot 111 of the assembly mechanism 100 is formed with absorption sites disposed at intervals in a circumferential array, further, the circumferential array of the positioning magnets 113 is disposed in a manner consistent with the array of the first magnet 510 or the second magnet 520 in the halbach array magnet, and further, the arrangement of the absorption sites formed on the accommodating slot 111 is also consistent with the array of the first magnet 510 or the second magnet 520 in the halbach array magnet, such that when the assembly magnets 500 of the same type are disposed on the accommodating slot 111, the assembly magnets 500 can be disposed in a manner consistent with the arrangement of the assembly magnets 500 in the halbach array magnet.

Further, in order to more accurately position the assembly magnet 500 placed on the receiving groove 111, referring to fig. 6, a plurality of limiting posts 112 are disposed on the receiving groove 111, specifically, the plurality of limiting posts 112 are also disposed at intervals in a circumferential array manner, and a limiting groove 117 capable of limiting the assembly magnet 500 is formed between two adjacent limiting posts 112. More specifically, each of the limiting grooves 117 is directly opposite to each of the positioning magnets 113, and therefore, a magnetic attraction force for attracting the mounting magnet 500 is formed in each of the limiting grooves 117. Thus, by arranging the limit posts 112, the assembly magnet 500 can be further positioned, that is, the limit groove 117 formed between two adjacent limit posts 112 can limit the assembly magnet 500 to match with the magnetic attraction of the positioning magnet 113, so that the assembly magnet 500 can be firmly positioned on the assembly mechanism 100, and when the flywheel 400 is pressed, the assembly magnets 500 cannot deviate from each other, thereby being beneficial to improving the assembly precision.

Further, each of the limiting grooves 117 is adapted to the assembling magnet 500, that is, when the assembling magnet 500 is installed in the corresponding limiting groove 117, the assembling magnet 500 contacts with the side wall of the limiting post 112. So, can carry out more accurate location to assembly magnet 500 to conveniently assemble magnet 500's pressfitting, be favorable to improving the assembly precision.

It is understood that the pressing mechanism 200 can abut against the assembling mechanism 100 to press the assembling magnet 500 adsorbed and positioned on the assembling mechanism 100 into the assembling slot 410 of the flywheel 400, in this arrangement, the flywheel 400 can be positioned by another fixture, and the pressing mechanism 200 pushes the assembling mechanism 100 to move toward the flywheel 400 to complete the pressing operation.
