[0001] The utility model relates to the technical field of machining, in particular to a split milling cutter head assembly. Background Technique

[0002] A milling cutter head is a device for installing and fixing a milling cutter, which has a wide range of applications in the field of machining. When milling a workpiece, the milling cutter is installed on the cutter head, and then the cutter head is driven to rotate by the spindle, so that the milling cutter rotates, and then the rotating milling cutter contacts the workpiece, thereby realizing the milling of the workpiece; in the prior art, a milling cutter head with a patent application number of 201921795833.6 mainly consists of a milling cutter head body and several milling cutters, and the milling cutters are installed in the installation grooves of the milling cutter head body; the inventor believes that there are the following problems in the use process. During the milling debugging of the workpiece, sometimes due to the operator's operation errors, such as tool setting errors, centering errors, and program calling errors, a collision phenomenon occurs, causing the milling cutter on the milling cutter head to collide with the workpiece, resulting in local impact deformation on the milling cutter head. Since the milling cutter head in the above prior art is of an integral structure, the deformed part cannot be replaced after local deformation, and only the whole milling cutter head can be replaced. However, the milling cutter head is relatively expensive, so its use is inconvenient and the economy is poor. Content of the Utility Model
