When it is necessary to control the position between the tool 41 and the material, the positions of the tool 41 and the cutter loading tray 4 can be adjusted by controlling the position of the feed box 2 on the frame 1. So as to realize the installation of raw materials and the cutter setting operation.

Referring to fig. 2 and 3, the transmission device 3 is disposed between the main shaft 11 and the cutter loading disc 4 and used for transmitting power, when the main shaft 11 rotates, the transmission device 3 drives the cutter loading disc 4 and the cutter 41 to rotate, the transmission device 3 not only can play a role in transmitting power, but also can connect the motion of the main shaft 11 with the motion of the cutter 41, so that the cutter 41 can rotate by a corresponding angle according to the rotation of the main shaft 11, meanwhile, the cutter 41 can process materials with a certain angle on the raw materials to cut, and further, the rotation speed ratio between the main shaft 11 and the cutter loading disc 4 can be adjusted to process different parts with polygonal cross sections.

The transmission between the first gear 32 and the second gear 33 is connected through the engaging gear 34, and the transmission between the first gear 32 and the second gear 33 has a larger moving space due to the clearance existing in the gear transmission, so that when the second gear 33 drives the first gear 32 to rotate, the second gear 33 can generate a larger cheap amount, and thus, when the second gear 33 drives the cutter loading disc 4 and the cutter 41 to rotate, larger errors can be allowed, and the safety of the cutter 41 in cutting is improved.

Referring to fig. 2 and 3, the engaging gear 34 is disposed on the base 31, the engaging gear 34 is rotatably connected to the base 31, a rotating bearing 35 is disposed at a central position of the engaging gear 34, an outer ring of the rotating bearing 35 is fixedly connected to the engaging gear 34, an inner ring of the engaging gear 34 is fixedly connected to the base 31, the base 31 and the engaging gear 34 are connected by the rotating bearing 35, and friction between the engaging gear 34 and the base 31 is converted into rolling friction of the rotating bearing 35, so that friction resistance of the engaging gear 34 during rotation is reduced, a service life of the engaging gear 34 is prolonged, and when a ratio of rotation speeds between the first gear 32 and the second gear 33 needs to be changed, only the engaging gear 34 needs to be replaced, thereby facilitating control of rotation speeds of the cutter mounting plate 4 and the cutter 41.
