Patent number: 11370041Abstract: The present invention relates to a slanting-bed feed processing machine tool of a large propeller. The machine tool comprises a slanting column feed bed, a machine tool spindle, a workpiece rotary worktable, a large propeller and a bed feed mechanism. The present invention coordinates the geometrical relationship between the machine tool and the large propeller to ensure that the slanting column feed bed moves between two blades, thereby reducing the overhang length of the spindle. Different forms of workpiece rotary worktables and bed feed mechanisms are selected according to different slanting column feed beds. Four types of slanting column feed beds are designed, which can be selected, optimized and applied for different processing objects. The present invention enhances the processing stiffness of the spindle and solves the problem of poor processing quality of the large propeller caused by machine tool vibration.Type: GrantFiled: February 28, 2020Date of Patent: June 28, 2022Assignee: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Yongqing Wang, Tianran Liu, Haibo Liu, Kuo Liu, Te Li, Dongming Guo
