Detailed Description

The application is described in further detail below with reference to fig. 2-5.

The embodiment of the application discloses a rotor assembly assembling tool. Referring to fig. 2 and 3, including support sleeve 6 and pressing piece 7, the installer places rotor 1 on support sleeve 6, and rotor 1 protruding position is located support sleeve 6, and rotor 1 plane supporting position contacts support sleeve 6 top surface, and support sleeve 6 supports rotor 1. The pressing piece 7 comprises a holding rod 71 and a pressing block 72 arranged at the end part of the holding rod 71, the holding rod 71 and the pressing block 72 are integrally formed, a supporting ring 8 is arranged on the outer side wall of one end, which is contacted with the holding rod 71, of the pressing block 72, and the supporting ring 8 is used for pressing the spring 3. When the spring 3 is used, an installer picks up the holding rod 71, inserts the pressing block 72 into the spring 3, positions and extrudes the spring 3, and the supporting ring 8 is matched with the pressing block 72 to extrude the spring 3, so that the installer can conveniently place the hole retainer ring 5.

Referring to fig. 2 and 4, the pressing block 72 includes a tapered portion 721 and a positioning portion 722 in contact with the support ring 8, the cross-sectional diameter of the tapered portion 721 gradually increases near the positioning portion 722, that is, the diameter of the tapered portion 721 gradually decreases away from the positioning portion 722. The convenient pressing block 72 is inserted into the spring 3, the positioning part 722 presses and positions the inner wall of the spring 3, and then the supporting ring 8 extrudes the spring 3. The support ring 8 comprises a sleeved part 81 which is closely attached to the positioning part 722 and a guide part 82 which is used for guiding the hole retainer ring 5 to enter the sleeved part 81, the section diameter of the guide part 82 is gradually reduced away from the sleeved part 81, and the hole retainer ring 5 is convenient to enter the rotor 1. The supporting surface of the supporting ring 8 is provided with a notch 9 along the length direction of the hand holding rod 71, and the notch 9 is provided with a flat position on the supporting ring 8, so that the earhole of the retainer ring 5 for the hole is effectively avoided. When the hole retainer ring 5 is placed in the rotor 1, the flat position is convenient for the supporting ring 8 to be separated from the hole retainer ring 5.

Referring to fig. 2 and 5, a plurality of annular protrusions 10 are fixed to the outer sidewall of the grip lever 71 in the length direction, and the annular protrusions 10 improve friction force of the outer sidewall of the grip lever 71, thereby facilitating force application of an installer.
