Therefore, the rotary cutter shaft 61 can be used more stably, and the deep hook bearing 64 can be removed at the same time when the tool holder 60 is removed from the tool magazine.

Further, the first bevel gear 54 may be fixed on the rotating shaft 53 by bolts, and in view of convenience in detachment, it is preferable that a positioning ring 55 is further disposed on the rotating shaft 53, the positioning ring 55 is disposed between two adjacent first bevel gears 54, when in installation, the first bevel gear 54 is installed first, then the positioning ring 55 is installed, then the next first bevel gear 54 is installed, and then the next first bevel gear 54 is installed, which are sequentially performed in this order, and finally, fixing the last first bevel gear 54 naturally limits the positioning of all the first bevel gears 54, so that the whole installation process is simpler and more convenient.

In order to further improve the stability of the installation of the rotating shaft 53 in the installation cavity 51, a limit bearing 56 is preferably further installed between the rotating shaft 53 and the side wall of the installation cavity 51, so as to fix the rotating shaft 53.

Further, preferably, the tool holder 60 is fixed to the outer periphery of the vertical tool magazine 50 by bolts.

In the present embodiment, before use, all the tool holders 60 with tools are mounted on the vertical tool magazine 50, and when the tool magazine is used, the vertical tool magazine 50 is driven by the vertical movable seat 43, so that the positions of the tools are adjusted to process a workpiece. The tool post 60 need not be completely mounted on the vertical magazine 50, and may be mounted as desired.

Further improved, because a large amount of heat is generated when the workpiece is processed, although the workpiece is cooled by the cooling liquid during processing, a large amount of heat is still transmitted to the clamp rail 30, and if the clamp rail 30 is heated to a large extent, due to the characteristic of thermal barrier contraction, although the deformation of the clamp rail 30 is very small, the movement of the clamp assembly 20 still generates a certain error, which leads to the damage of the processing precision, therefore, preferably, a plurality of heat dissipation holes 80 are arranged at the bottom of the clamp rail 30, the heat dissipation area of the clamp rail 30 is further increased by the heat dissipation holes 80, meanwhile, the heat dissipation holes 80 can also play a role of circulating the scraps, the cooling liquid flows into the surface of the rack 10 after cooling the workpiece, one can dissipate the heat of the clamp rail 30 through the area of the large heat dissipation holes 80, and the other can clean and wash the scraps at two sides of the clamp rail, and then flows to a specific position through the heat radiating holes 80, so that the scraps can be better collected.

Further improve, traditional louvre 80 mostly all directly adopts the square hole design, because it is more convenient to process, but the inventor discovers in practical application, because installed a large amount of work pieces on the frame 10, lead to anchor clamps track 30 atress great, for this reason can save a large amount of stresses in the right angle corner of louvre 80, lead to using the back for a long time, the corner of louvre 80 often all can produce the crackle, for this strand of stress of dispersion, can not appear the crackle on messenger's anchor clamps track 30, it is preferred that be the circular arc transition between each adjacent lateral wall of louvre 80. In order to further disperse the stress, it is preferable that the side wall of the heat dissipation hole 80 and the outer side wall of the clamp rail 30 are also in arc transition.
