Then, the brake servo motor 21 is started, and the output end transmission screw 20 of the brake servo motor 21 rotates synchronously. The rotated screw 20 will perform a spiral meshing transmission on the meshing nut 22, so that the meshing nut 22 drives the first transmission curved plate 17 to automatically move linearly through the first linkage plate 23. At the same time, the first tooth plate 24 moves linearly along with the first transmission curved plate 17 and synchronously meshes and transmits the second linkage plate 26 through the second tooth plate 25, thereby causing the second linkage plate 26 to drive the second transmission curved plate 18, the liquid outlet fixture seat 2 and the liquid inlet fixture seat 3 to automatically move close to each other until the first positioning fixture 4 on the top of the liquid outlet fixture seat 2 is adapted to be engaged with the rotor liquid outlet 14 on the first rotor component 12, and the brake servo motor 21 is closed; After the first rotor component 12 and the second rotor component 13 are assembled, start adjusting the corresponding dial gauge probes of the first dial gauge 6 and the second dial gauge 7 so that the port surface at one end of the rotor liquid inlet 15 contacts the dial gauge probe of the second dial gauge 7, and the port surface at one end of the rotor liquid outlet 14 contacts the dial gauge probe of the first dial gauge 6. After completion, fix the dial gauge and rotate the dial of the dial gauge so that its pointer points to the 0 position; By hand-cranking the rotor rocker 10, the rotor rocker 10 is used to synchronously drive the cylindrical frame 51 through the transmission shaft and the synchronous belt 11, and the rotor liquid inlet 15 engaged with the limit groove 53 will drive the first rotor component 12 and the second rotor component 13 to rotate synchronously. At the same time, the micrometer probe of the first micrometer 6 will perform circular runout detection along with the port surface of the corresponding rotating rotor liquid outlet 14. Similarly, the micrometer probe of the second micrometer 7 will perform circular runout detection along with the port surface of the corresponding rotating rotor liquid inlet 15, and the circular runout degree is obtained from the maximum scale change of the pointer transmitted to the first micrometer 6 or the second micrometer 7.

Specifically, one end of the rotor liquid inlet 15 is clamped and connected to the middle space of the second combination cylinder 52. At the same time, the multiple plate-like structures in the middle of the rotor liquid inlet 15 are respectively clamped with the corresponding number of limit grooves 53. After the second rotor component 13 is installed, the first rotor component 12 and the second rotor component 13 are buckled and assembled. Then, the brake servo motor 21 is started, and the output end transmission screw 20 of the brake servo motor 21 rotates synchronously, and the rotated screw The lever 20 performs a spiral engagement transmission on the meshing nut 22, so that the meshing nut 22 drives the first transmission curved plate 17 to automatically move linearly through the first linkage plate 23. At the same time, the first tooth plate 24 moves linearly along with the first transmission curved plate 17 and synchronously engages and transmits the second linkage plate 26 through the second tooth plate 25, thereby causing the second linkage plate 26 to drive the second transmission curved plate 18, the liquid outlet fixture seat 2 and the liquid inlet fixture seat 3 to automatically move close to each other until the first positioning fixture 4 on the top of the liquid outlet fixture seat 2 is adapted and engaged with the rotor liquid outlet 14 on the first rotor component 12, and the brake servo motor 21 is closed. The first transmission curved plate 17 is used to detect the displacement data of the combination of the first rotor component 12 and the second rotor component 13, and the displacement data pre-measured on the standard parts are compared. If it is within the error range, it means that the appearance dimensions of the first rotor component 12 and the second rotor component 13 are qualified. If it is not within the error range, it means that the appearance dimensions of the first rotor component 12 and the second rotor component 13 are unqualified and need to be repaired.
