One retaining ring 202 and a shaft 201, have an annular groove 2011 in the shaft 201, and the assembly tooling structure 100 includes pedestal
1, upper cover 2, pressing sleeve 3, plug 4, thimble 5 and spring 6；There is an accommodating cavity 11, radial internal diameter and rotor inside the pedestal 1
204 outer diameter of iron core matches, and 200 iron core 204 of rotor can move up and down in the accommodating cavity 11, and the bottom of the pedestal 1 is envelope
Closed end 12, top is open end 13, and an inner circle seam allowance 131 is equipped at the open end 13；The lower part of the pedestal 1 is equipped with one
Through-hole 14, the through-hole 14 are connected to accommodating cavity 11.
Setting from top to bottom and each other neighbour are equipped with referring again to Fig. 2, Fig. 5, Fig. 6 and Fig. 7, at the vertical center of the upper cover 2
The small open-work 21 and open cavity 22 connect, the bottom of the upper cover 2 are inserted in the inner circle seam allowance 131；The top of rotor 200
It is placed in the open cavity 22.The pressing sleeve 3 includes small diameter portion 31, large diameter hole 32 and diameter holes 33, the small diameter portion 31
In the lower part of pressing sleeve 3, the large diameter hole 32 and diameter holes 33 are from bottom to up set on the vertical centerline of pressing sleeve 3；The pressing sleeve 3 is also
Including large-diameter portion 34, the large-diameter portion 34 is adjacent to the top of small diameter portion 31, when in running order, the bottom end of large-diameter portion 34
It is connected to the top of upper cover 2.The plug 4 includes path section 41, tapered section 42 and the major diameter section 43 set gradually from top to bottom,
41 outer diameter of path section matches with 33 internal diameter of diameter holes, and the path section 41 is less than 202 internal diameter of retaining ring, major diameter section
43 outer diameters are equal to 201 outer diameter of shaft, and internal diameter and 43 outer diameter of major diameter section of the large diameter hole 32 match；When in work shape
When state, the retaining ring 202 is sheathed on plug 4, and the diameter holes 33 of pressing sleeve 3 are socketed in the path section 41, the small diameter portion
