[0023] Specific implementation and principle:

[0024] In actual application of the present invention, the flexible flywheel 9 is installed on the positioning pin 31 through the center hole thereon, the piston rod of the lifting cylinder 14 is started to extend, driving the protective cover 5 and the file insertion mechanism 6 to move downward, and the positioning pressure column 51 of the protective cover 5 presses and positions the flexible flywheel 9, then the piston rod of the cylinder 61 is driven to retract, and the moving plate 63 is driven to move horizontally through the driving plate 64, and the file driving block 65 on the moving plate 63 drives the file 4 and the file base 71 to move, and a total of 10 groups of files are inserted into the signal hole of the flexible flywheel 9, and then the piston rod of the lifting cylinder 81 is controlled to extend, driving the file limit plate 84 to move upward, and the file limit plate 84 is located on the outside of the file 4, and the file limit plate 84 limits the file 4 , ensuring that the file 4 does not separate from the workpiece during movement, and then the piston rod of the driving cylinder 61 is quickly extended, and the file driving block 65 is quickly separated from the file 4. Under the action of the elastic force of the spring 73, the file 4 and the file base 71 move repeatedly on the supporting plate 2, and the file 4 performs multiple round-trip grinding and deburring on the workpiece. After the grinding is completed, the piston rod of the lifting cylinder 81 is controlled to retract, and the file limit plate 84 moves downward accordingly. Under the action of the elastic force of the spring 73, the file 4 automatically withdraws from the workpiece and abuts against the file driving block 65, and then the output shaft of the servo motor 3 is controlled to rotate, driving the flexible flywheel 9 to rotate, and then repeating the above action. After the workpiece is rotated 12 times in total, all the burrs of the signal holes are ground off, and a workpiece is processed.

It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the present utility invention and technical solution are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
