Abstract

The invention discloses a method and device for achieving full-profile grinding of blades with tenons through a cylindrical coordinate three-axis linkage machine tool. The device is characterized in that the blades are mounted on a rotating shaft of a numerical control machine tool in a manner that the tenons are arranged upwards, and the three-axis linkage machine tool is formed by other two linear shafts of the numerical control machine tool and the rotating shaft; the three-axis linkage machine tool is used for driving a disc grinding wheel to carry out full-profile grinding machining on the blades; a rotating shaft of the grinding wheel is not parallel to or perpendicular to a rotating working table of the machine tool or the axis of the rotating shaft, the phenomenon that the length of the grinding wheel is shortened is avoided, and the long blades are machined; according to the method, only through three motion axes, the tenons and profiles of the blades can be comprehensively machined; the machine tool manufactured through the method has the coat far below a five-axis linkage numerical control machine tool, and a square matrix structure is formed through a plurality of spindles and the rotating shaft, so that multiple blade parts can be machined on the same machine tool, and the production efficiency of the machine tool can be obviously improved.

Description

technical field

[0001] The invention relates to a full-profile grinding method and device for a blade with an edge plate and a tenon at one end, in particular to a method and a device for realizing full-profile grinding of a blade with a tenon by using a cylindrical coordinate three-axis linkage machine tool, belonging to The technical field of blade machining. Background technique

[0002] At present, the tenon, edge plate and airfoil of blades with complex profiles are usually milled on a five-axis machine tool with A-axis and B-axis, and the middle part of the airfoil is usually milled with a high-efficiency belt round Corner end milling is used for milling, while the edge plate and the part near the edge plate on the blade body are basically milled with a ball-end cutter, and the tenon part is usually shaped and ground on a slow-feed grinder. The machining process of this processing method needs to change the tool, which will cause the knife connection mark at the knife...
