When the motor rotor is in an initial position, the motor rotor is vertically downward, a shaft sleeve is arranged below the motor rotor, a sleeve rod 334 is aligned with a hole of the shaft sleeve, a mandril of a fifth air cylinder 331 is ejected when the motor rotor works, the sleeve rod 334 is inserted into the hole of the shaft sleeve, the sleeve rod 334 can clamp the shaft sleeve due to the fact that the diameter of the sleeve rod 334 is larger than a certain numerical value of a motor rotor shaft, the mandril of the fifth air cylinder 331 is reset at the moment, the shaft sleeve moves upwards along with the sleeve rod 334, then a rotating device 332 rotates for 90 degrees to drive the sleeve rod 334 to rotate for 90 degrees, the sleeve rod 334 is aligned with a shaft of the motor rotor tightly pressed on a motor rotor positioning block 24 at the moment, the mandril of a sixth air cylinder 333 is ejected, the sleeve rod 334 is contacted with the shaft of the motor rotor and generates flexible collision under the action of a first spring, then the sleeve rod 334 contracts inwards, the shaft sleeve is sleeved on the shaft of the motor rotor, and the primary sleeving is completed.
When the press-in mechanism works, the ejector rod of the seventh air cylinder 321 is ejected, the end face of the press-in rod 322 is in contact with the end face of the shaft sleeve, the press-in groove 323 gives way for the shaft of the motor rotor, the depth of the press-in groove 323 is set according to the required press-in distance, and when the shaft of the motor rotor is in contact with the bottom of the press-in groove 323, the ejector rod of the seventh air cylinder 321 is reset to complete the press-in of the shaft sleeve.
