Detailed Implementation The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0009] like Figure 1-3 As shown, an adaptive polishing device for aero-engine blades includes a support base 1. An electric cylinder 2 is fixedly mounted on the top center of the support base 1 by screws. A transmission arm 3 is fixedly mounted on the top of the piston rod of the electric cylinder 2 by screws. A docking shaft 4 is rotatably connected to the end of the transmission arm 3. A U-shaped seat 5 is welded to the bottom of the docking shaft 4. Mounting seats 6 are integrally formed and symmetrically connected to the two ends of the bottom of the U-shaped seat 5. A support arm 7 and a transmission motor 8 are provided on the mounting seat 6. The support arm 7 is integrally formed and symmetrically connected to both sides of the mounting seat 6. The transmission motor 8 is fixedly mounted on the outer center of the mounting seat 6 by screws. The main shaft of the transmission motor 8 passes through and extends to the inner side of the mounting seat 6, where a polishing wheel 9 is fixedly mounted by screws. A light shaft 10 is slidably connected to the outer end of the support arm 7 by a copper sleeve. A limit seat 11 is fixedly mounted on the outer end of the light shaft 10 by screws. A compression spring 12 is fitted on the light shaft 10 between the limit seat 11 and the outer side of the support arm 7. Specific usage: Connect the electric cylinder 2 and the drive motor 8 to the external PLC control cabinet via wires; install and fix the support base 1 on one side of the aircraft engine blade clamping seat. At this time, the U-shaped seat 5 is fitted onto the outside of the aircraft engine blade, and the polishing wheel 9 is pressed against both sides of the lower end of the aircraft engine blade by the compression spring 12; then start the drive motor 8 to drive the polishing wheel 9 to rotate and polish the aircraft engine blade. At the same time, start the electric cylinder 2 to drive the drive arm 3 to move linearly upward. The linear upward movement of the drive arm 3 drives the U-shaped seat 5 to move linearly upward. The linear upward movement of the U-shaped seat 5 drives the polishing wheel 9 to move linearly upward along the aircraft engine blade to perform the polishing operation; at the same time, the U-shaped seat 5 can rotate around the drive arm 3, which allows the polishing wheel 9 to easily rotate and move along the curved surface of the aircraft engine blade.
