Description

Technical Field

[0001] The utility model relates to the technical field of blade disk processing, and more specifically, to an integral blade disk processing device for an aero-engine. Background Art

[0002] Aircraft engines are highly complex and sophisticated thermal machines. As the heart of an aircraft, they are not only the driving force for the flight of an aircraft, but also an important driving force for the development of aviation. Every important change in the history of aviation is closely related to the technological progress of aircraft engines. The blisk is an important part of the engine, and the integral blisk is designed to integrate the blades and disks of the engine rotor into a whole, and is manufactured by integral processing or welding methods.

[0003] After searching, the utility model patent with announcement number CN208304087U discloses a processing equipment for an integral blade disk of an aircraft engine, which includes a machine tool rotating axis and a linear axis. The X-axis is located at the lower end, and the Y-axis is placed on the X-axis. The two axes are crossed at 90 degrees, and the X-axis and Y-axis drive the blade disk blank to move horizontally. The A-axis turntable is placed on the Y-axis, and the A-axis of the machine tool drives the blade disk to rotate around the X axis respectively. The Z1 axis is placed on the A-axis, driving the blade disk to move vertically and adjust the cutting height of the blade disk. The C-axis turntable is connected to the Z1 axis, and the C-axis controls the horizontal rotation of the blade disk so that the molybdenum wire can cut blades at different angles; the Z-axis is placed at the upper end of the column, connected to the V-axis below, and the lower end of the V-axis is connected to the U-axis. The upper wire arm is connected to the U-axis, the Z2 axis is placed at the lower end of the column, the lower wire arm is connected to the Z2 axis, and the wire barrel is placed behind the column. However, the above patent still has the following shortcomings: when the blade disk is subjected to electric spark wire cutting, the waste chips generated by the blade disk cutting are not convenient to be cleaned in time, which affects the processing accuracy. In addition, some waste chips will fall under their own weight, which makes it difficult to collect the waste chips. For this reason, we propose an aircraft engine integral blade disk processing equipment. Utility Model Content
