[0002] A milling cutter head is a tool used for milling processing, usually composed of a cutter head and multiple blades. It can be installed on a milling machine according to different processing requirements to perform various operations such as cutting, engraving, and forming of various materials. The selection of the milling cutter head needs to consider factors such as the processing material, processing accuracy, and processing efficiency.

[0003] In the prior art, generally, the milling cutter head first grinds the plane. However, for some workpieces that need to grind grooves or inner holes, the milling cutter head needs to have a certain adjustment ability to adapt to workpieces of different shapes. The traditional adjustment method of the milling cutter head is relatively complex and needs to be achieved by replacing different blades or adjusting the installation position of the blades, which is not only time-consuming but also inefficient. Therefore, the present invention provides a milling cutter head that is convenient for adjusting the working position. Summary of the Invention

[0028] Working principle: When in use: By controlling the rotation of the top disc box 1, the rotation of the milling cutter chassis 2 is controlled, so that the grinding milling cutter 3 performs planar grinding. By controlling the up and down movement of the synchronous ring 27, the up and down movement of the adjusting moving ring 8 is controlled.

When the adjusting moving ring 8 is in the middle position, the bottom outer teeth 14 are engaged with the bottom inner teeth 15, and the top outer teeth 12 are engaged with the top inner teeth 17, so that the rotating outer ring 7 and the inner turntable 9 rotate synchronously, making the overall rotating outer ring 7 and the inner turntable 9 rotate synchronously. At the same time, the synchronous ring 27 rotates synchronously, and the expansion threaded roller 10 rotates, so that the entire structure rotates for grinding. By the up and down movement of the expansion pressure disc 18, the up and down movement of the expansion mounting box 31 is pushed. Through the inclined surface of the inclined groove row, the expansion adjustment block 34 moves along the inclined surface, making the two inner excavation milling cutters 35 approach or move away from each other, so as to adjust the width of the required slot or the diameter of the hole. By controlling the up and down movement of the inner excavation disc 29, the depth of the slot and the hole is adjusted. By installing the mounting disc 4 on the machine tool, the rotation of the rotating mounting seat 5 is controlled by installing a motor, and the pushing of the push mounting ring 6 is controlled by an electric cylinder, so that the structure can adjust the grinding.
