Zusammenfassung:	Spiral gear machining equipment capable of ascending and descending is used when a blank (85) is machined. The spiral gear machining equipment comprises a base (3), a stand column (300), a milling head (301), a rotary inner threaded part (1), an outer threaded part (2) and a cylindrical workpiece bearing part (8), wherein the base (3) is fixedly connected with the lower end of the stand column (300), a lifting device (101) is installed at the upper end of the stand column (300), a milling head (301) is installed at the upper end of the lifting device (101) and can mill the blank (85) through rotation of a milling cutter, the rotary inner threaded part (1) comprises an upper barrel part (11) and a lower cavity part (12), the lower cavity part (12) is rotationally connected with the base (3) in the peripheral direction and fixedly connected with the base (3) in the axial direction trough a bearing device (13), and the outer threaded part (2) is cylindrical.
