[0025] First, the mounting plate 5 can be moved by the electric push rod 4, so that the gear can be positioned and clamped by the cooperation of the limiting plate 7 and the support plate 6. Then, the surface of the gear can be easily processed. Then, the height of the auxiliary plate 10 can be adjusted by the moving screw 8, so that the auxiliary plate 10 can assist in positioning the upper surface of the gear, thereby improving the clamping stability of the gear and facilitating subsequent processing.

The limiting plate 7 is fixedly connected to the side of the installation plate 5. The limiting plate 7 has an overall arc-shaped plate structure.

[0027] In use, the mounting plate 5 can be pushed by the electric push rod 4, so that the limiting plate 7 and the support plate 6 can clamp and support the gear. Then, the gear after positioning can be easily processed. The height of the gear after positioning can also be adjusted by the lifting hydraulic rod 2 to facilitate subsequent processing of the gear.

[0028] Example 3: Based on Example 2, a support plate 6 is provided to facilitate the positioning of the gear shaft.
