[0006] The support mechanism has two mounting plates installed inside the mounting cabinet, and a fixing plate is installed on the upper end of the mounting plate;

[0007] The first measuring mechanism includes a first stabilizing plate installed on the upper end of one of the first limiting blocks, and a first high-precision thickness gauge is installed on the upper end of the first stabilizing plate;

[0008] The second measuring mechanism includes a second limiting block mounted on the upper end of another fixed plate, an inner rotor mounted on the upper end of the second limiting block, a second stabilizing plate mounted on the upper end of the fixed plate, and a second high-precision thickness gauge mounted on the upper end of the second stabilizing plate.

[0009] The second thickness measuring component includes a moving mechanism installed inside the mounting cabinet. Several lifting mechanisms are equidistantly installed on the upper end of the moving mechanism, and a third measuring mechanism is provided at the lower end of each of the lifting mechanisms.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. When measuring the installation clearance of the rotating shaft, firstly, place the outer rotor and inner rotor on the top of the first and second limiting blocks respectively. The program calculates two sets of height dimensions, which are displayed on the control panel screen. Simultaneously, a set of lights on both sides of the rotor assembly placement box on the right illuminates, indicating that the appropriate inner and outer rotors should be retrieved from the box. After retrieval, the lights automatically turn off, thus completing the dimensional adaptation between the rotor and the housing. Next, control the first guide block to automatically move along the first guide rail to the two stations on the left, carrying the first limiting block. Using the first and second high-precision thickness gauges, the height difference between the inner and outer rotors after installation can be measured to ensure it meets the clearance requirements.

After measuring the inner and outer rotors separately, the inner and outer rotors are placed simultaneously in the placement slot of the placement plate. The second guide block moves along the second guide rail, and then the measuring cylinder is controlled to lower the connecting plate. The pressure plate clamps the inner and outer rotors to ensure measurement accuracy. The installation gap between the inner and outer rotors can be further measured by a third high-precision thickness gauge. Compared with the optional tooling in the prior art, this utility model can perform dual high-precision installation gap measurement operations for the inner and outer rotors through the cooperation of the above structures, thereby significantly improving the measurement accuracy and enhancing the practicality of the optional tooling.

[0048] Working Principle: In use, the outer rotor 2025 and inner rotor 2042 are first placed on the upper ends of the first limiting block 2023 and the second limiting block 2041, respectively. The height is calculated into two sets of dimensions by the program. Then, the first guide block 2022, carrying the first limiting block 2023, automatically moves along the first guide rail 2021 to the two stations on the left. The first high-precision thickness gauge 2032 and the second high-precision thickness gauge 2044 measure whether the height difference between the inner rotor 2042 and the outer rotor 2025 after installation meets the clearance requirements. This allows for the compensation of different workpiece dimensional errors by selecting rotor accessories of different sizes. After measuring the inner rotor 2042 and the outer rotor 2025 respectively, the inner rotor 2042 and the outer rotor 2025 are placed simultaneously in the placement slot 3042 of the placement plate 3041. The second guide block 3014 moves along the second guide rail 3013. Then, the measuring cylinder 3021 is controlled to lower the connecting plate 3023. The pressure plate 3034 clamps the inner rotor 2042 and the outer rotor 2025 to ensure measurement accuracy. Finally, the installation gap between the inner rotor 2042 and the outer rotor 2025 can be further measured by the third high-precision thickness gauge 3032, thereby ensuring measurement accuracy and enhancing the practicality of the selected tooling.
