Description

Technical Field

[0001] This utility model relates to the field of cyclone milling machine technology, and in particular to a cyclone milling machine power head and a cyclone milling machine. Background Technology

[0002] A cyclone milling machine is a special machine tool that performs thread machining by rotating a cutting tool at high speed. The power head of a cyclone milling machine is used to mount and drive the cutting tool. The cutting tool is disc-shaped with a pre-drilled machining hole in the center for workpiece movement. This results in a relatively large thickness of the transmission mechanism driving the cutting tool in the direction of the machining hole axis. Furthermore, the cyclone milling machine requires an angle adjustment mechanism to change the angle of the power head relative to the workpiece. However, the excessive thickness of the power head in the direction of the machining hole axis causes interference between the machining hole and the workpiece when the angle adjustment mechanism adjusts the power head angle, thus limiting the range of angle adjustment that the mechanism can change.
