[0002] A five-axis linkage CNC machine tool is a machine tool with high scientific and technological content, high precision, and is specially used for machining complex curved surfaces. This high-precision machining system has a crucial influence on industries such as a country's aviation, aerospace, military, scientific research, precision instruments, and high-precision medical equipment. At present, the five-axis linkage CNC machine tool system is an important means to solve the machining of impellers, blades, marine propellers, heavy generator rotors, steam turbine rotors, large diesel engine crankshafts, etc.

[0003] For the existing five-axis linkage machine tools, although different machining functions can be achieved by changing the layout on the machine tool, the machining angle of the tool head part cannot be adjusted, so that the tool head cannot rotate, and thus the machining position of the tool head cannot be changed. Moreover, the existing equipment has a complex structure and is troublesome to use, and is very inconvenient in later maintenance, resulting in a long maintenance time and high cost in later stage, increasing the operating cost of the enterprise.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Content of the Utility Model
