[0026] The utility model provides a power boring and milling head for a vertical turning, milling and boring composite CNC machine tool, and the specific working principle is as follows: when the flange 2 needs to be installed and connected with the rotating disk of the machine tool, the flange 2 is first pushed close to the surface of the rotating disk of the machine tool until the surface of the flange 2 at one end of the transmission shaft 1 is fitted and connected with the surface of the rotating catch, and then the end of the mounting bolt 8 on the surface of the mounting ring 6 is pressed together, so that one end of the mounting bolt 8 moves inside the connecting tube 7 and extends into the screw hole on the surface of the flange 2. At the same time, the limiting ring 10 of the nickel coin of the connecting tube 7 is squeezed and a The utility model is used to deform and separate from the inner part of the limiting ring groove 11, so that one end of the mounting bolt 8 can be connected with the flange 2 in a limiting manner, and then the mounting bolts 8 are rotated one by one, so that the end of the mounting bolt 8 can be extended to the inner part of the rotating disk, and in the process of rotating the mounting bolts 8, the transmission shaft 1 will not be easily offset, which is convenient for improving the installation efficiency of the workers and has a good practical effect. When the cutter head 4 is installed and connected with the mounting seat 3 in the early stage, one end of the cutter head 4 is first pushed to move and engage with the temporal part of the mounting groove 12 until one end of the cutter head 4 is moved to a suitable position When the tool 4 is installed, it is necessary to pull one end of the limit post 15 so that the one end of the limit post 15 moves toward the outside of the installation socket 17. At this time, the connecting spring 16 will be stretched and a certain rebound force will be generated until one end of the limit post 15 is limitedly engaged with the inside of the limit slide groove 14. Then, the cutter head 4 is pushed continuously so that one end of the cutter head 4 can be completely engaged with the inside of the installation slot 12. Then, one end of the limit post 15 can be released. At this time, the rebound force generated by the connecting spring 16 will act on the limit post 15, so that the other end of the limit post 15 can pass through the inside of the through slot 18. , and the other end of the limiting clamp column 15 will extend to the inside of the second mounting screw hole 13. At this time, the bolt is screwed into the inside of the second mounting screw hole 13 through the first mounting screw hole 5, and then one end of the limiting clamp column 15 is pulled again. The worker can continue to rotate the bolt so that the bolt can fix the cutter head 4 for installation. Then, the end of the limiting clamp column 15 is loosened so that the other end of the limiting clamp column 15 can be limitedly engaged with the fixing ring groove on the surface of the bolt, thereby realizing the limited fixation of the bolt, so that after the cutter head 4 is fixedly installed, the bolt will not easily become loose, and the practicality is better.

At the same time, the corresponding surfaces can be processed by replacing the cutter head 4 according to different processing requirements. It is worth noting that the bottom surface of the workpiece to be processed is connected to the workbench and cannot be processed. At the same time, during the operation of the vertical boring, milling and turning compound CNC machine tool, the clamping workbench can realize indexing and locking processing.
