[0030] Working principle:
[0031] When using the inner circle runout inspection fixture, the runout is detected by the wall thickness difference method. The flywheel gear ring is put on the measuring circular block, and the operating lever 7 is pressed so that the measuring head 8 is squeezed onto the arc surface of the inner circle of the flywheel gear ring, so that the measuring gauge 6 gives a depth indication.

The runout of the inner circle of the flywheel gear ring is judged according to the difference in the inspection data. When it is necessary to adapt the inner circle diameter of the flywheel gear ring, the flywheel gear ring is put on the arc surface of multiple arc blocks 21, and the motor 26 is started. With the encoder, the bevel gear 2 25 rotates, the bevel gear 1 24 rotates, and the screw rod 23 rotates. Under the limitation of the square rod 22, the square rod 22 is pushed, thereby pushing the arc block 21, so that multiple arc blocks 21 extend outward, thereby adapting to the flywheel ring gear, and then adapting to the flywheel ring gear as much as possible, which is convenient for detection. A small gap is left between the multiple arc blocks 21 and the flywheel ring gear to facilitate the rotation of the flywheel ring gear, rotate the mounting panel 4, and after rotation, insert the pin 32 into the mounting panel 4 and the mounting frame 1 to fix it, so as to adjust the angle of the mounting panel 4, and fix the mounting panel 4 by setting the pin 32 and the positioning hole 33. Fix the mounting panel 4 by setting the pin 32 and the positioning hole 33.
