Detailed Description
Referring to fig. 1-5, the shaft sleeve mounting tool for the mixed-flow turbocharger consists of an axial positioning rod 1, a tool pressing nut piece 11, an inner hexagonal screw II 12, a tool pressing check ring 13, a tool pressing thrust bearing 14, a tool pressing locking sleeve 15, a shaft pressing sleeve 16, a shaft sleeve 8, a thrust block 9 and a main shaft 10.
The installation process of the shaft sleeve pressing tool is as follows:
Step 1: mounting a press tooling thrust bearing 14 on a press tooling thrust bearing mounting end face 15b (limit step) of a press tooling locking sleeve 15; subsequently, the press tooling nut piece 11 is matched and installed with the press tooling thrust bearing 14; the inner hexagon screw II 12 fixes the pressing tool check ring 13 on the pressing tool locking sleeve 15, so that the pressing tool thrust bearing 14 and the pressing tool nut 11 have smaller axial movement space, and the pressing tool thrust bearing 14 and the pressing tool nut 11 can radially rotate when the shaft sleeve 8 is installed.
Step 2: a sleeve 16 of the pressing shaft sleeve is arranged on the main shaft 10 and matched with the shaft sleeve 8;
Step 3: the axial positioning rod 1 is matched and screwed on the main shaft 10 by using a spanner to match with the hexagonal head structure 1a of the axial positioning rod;

The process of installing the shaft sleeve by the shaft sleeve pressing tool is as follows:
When the shaft sleeve is used for mounting the shaft sleeve, the axial positioning rod 1 is fixed by using a wrench, the other wrench is used for screwing the tool nut 11 to move towards the direction close to the main shaft 10, the tool nut 11 pushes the tool thrust bearing 14, the tool locking sleeve 15 and the shaft sleeve 16, and then the shaft sleeve 16 pushes the shaft sleeve 8 to move towards the thrust block 9, so that the shaft sleeve is assembled.
When the tool nut 11 is screwed and rotated, the tool thrust bearing 14 and the tool thrust bearing mounting end face 11d in the tool nut 11 rotate along with the tool nut 11, and under the action of the ball in the middle of the tool thrust bearing, the matched end faces in the tool thrust bearing 14 and the tool locking sleeve 15 cannot rotate, so that radial movement of the tool locking sleeve 15 and the shaft sleeve 16 and the shaft sleeve 8 cannot be generated when the shaft sleeve 8 axially moves, mutual friction between the tool locking sleeve 15 and the shaft sleeve 16 and between the shaft sleeve 16 and the shaft sleeve 8 is avoided, uneven axial stress of the shaft sleeve 8 in the mounting process is avoided, the shaft sleeve 8 and the spindle 10 cannot be protected from being scratched or pulled, and the shaft sleeve mounting process can be stably performed.
