Abstract

The invention provides an extension milling head structure, which belongs to the field of milling heads and comprises a main mounting plate, wherein fixing through holes are symmetrically formed in the bottom surface of the main mounting plate, and friction and vibration of a main shaft body in the rotating process are effectively reduced and the processing precision is improved through the arrangement of a stabilizing bearing and a top supporting bearing. Meanwhile, the accurate sleeving design of the inner supporting tube ensures the stable operation of the spindle rod body. The design of the positioning column body and the limiting connecting groove realizes the accurate butt joint of the milling head and the output end of the machine tool, and further improves the machining precision and the repeated positioning precision. The extension rod body adopts an integrated forging structure, and has higher overall rigidity and deformation resistance compared with the traditional splicing structure. In the processing process, vibration can be effectively reduced, and the processing precision and the surface quality are improved. The inner reinforcing pipe is arranged between the inner supporting pipe and the main shaft body, so that the rigidity of the structure is further enhanced, and stable processing performance can be still maintained during long-distance extension processing.
