The movable disk 52 and the hinge shaft 32 are both movable, and the gear can be adjusted to the angle required for milling. Different inclination angles can be processed. Remember that the transmission shaft 54 ​​can control the feed amount of the gear to ensure the processing accuracy of the equipment, so that the clamping tooling has good applicability.

[0040] like Figure 7As shown, in order to reduce the situation where there are a large number of debris residues in the gear gap after processing, a plurality of hollow shafts 56 are provided on the outside of the transmission shaft 54.

[0043] Then, when it is necessary to mill the inclination angle of the gear edge, the hinge shaft 32 on one side is retracted, and the hinge shaft 32 on the other side can adjust the position of the clamping pressure plate 34 so that the lockable ball on its inner wall can abut against the gear surface, and the auxiliary transmission mechanism 5 can abut against both ends of the gear to assist in positioning the gear, and at the same time can be adjusted according to the angle of milling required, the movable plate 52 and the hinge shaft 32 are both movable, and the gear can be adjusted to the angle required for milling, and can be flexibly adjusted according to the use situation, so that the clamping tool has good applicability, and in the process of driving the gear to rotate, the transmission shaft 54 ​​can be rotated, and the gear can be driven to rotate, and the movable sheet 561 can move between the gear gaps, and can shake off the debris generated by grinding to prevent it from accumulating in the gear gaps, and in the process of the transmission shaft 54 ​​rotating, it can be abutted against the outer gap of the gear with the help of the swing shaft 57, and can move inside the outer teeth during the transmission process, which can reduce the residue of debris;

[0044] Finally, during the transmission process, the elastic pressure plate 35 can press the grid plate against the two ends of the gear under the elastic action, so as to quickly clean the outer wall of the gear that has been milled, collect fine metal chips while cleaning large particles of debris, and filter out the cutting fluid inside, thereby reducing the situation where debris flies and accumulates on the operator's cuffs and clothes during air blowing cleaning after processing.
