A limit rod 35 passes through the threaded hole. The surface of the limit rod 35 is threaded. A handle is fixedly connected to the upper end of the limit rod 35. Rotating the handle can cause the limit rod 35 to move vertically on the connecting block. When the limit rod 35 contacts the end of the rocker arm 34, the rotation of the rocker arm 34 is limited by friction, thereby limiting the position of the adjusting plate 31. Working principle: The operator places the gear to be inspected on the clamping assembly. By adjusting the clamping assembly, gears of different sizes can be fixed. The gear is then moved to the inspection assembly to inspect it before processing. The rotating motor 5 can inspect any position of the gear. A corresponding rack 21 is installed on the processing assembly. The rocker arm 34 is rotated to make the gear mesh with the rack 21. The rack 21 reciprocates, causing friction on the gear. After processing, the gear is moved to the inspection assembly again to compare the inspection parameters before and after processing. After inspection, the gear can be removed.
