[0032] In this embodiment, the rubber pad 13 is provided to protect the L-shaped plate 1 .

[0033] Working principle: When the engraving and milling machine body 2 processes parts and needs to reduce noise, the staff will power on the servo motor 701 plug and start the external controller of the servo motor 701, so that the output end of the servo motor 701 drives the screw 702 to rotate on the inner surface of the rectangular plate 703, so that the rectangular plate 703 drives the driving plate 704 to move downward. At the same time, the driving plate 704 drives the noise reduction frame 3 to slide downward on the outer surface of the slide rail 11, and the noise reduction frame 3 drives the buffer pad 5 to move downward and fit tightly with the connection between the L-shaped plate 1, so that the noise reduction frame 3, the buffer pad 5 and the sound insulation board 4 are used in combination to quickly seal and reduce noise on the engraving and milling machine body 2, thereby preventing employees from suffering from occupational ear diseases caused by noise;

[0035] When the engraving and milling machine body 2 needs to be maintained, or the engraving and milling machine body 2 is processed and the parts need to be taken out, the staff starts the external controller of the servo motor 701 again, so that the output end of the servo motor 701 drives the screw 702 to rotate in the opposite direction on the inner surface of the rectangular plate 703, so that the rectangular plate 703 drives the driving plate 704 to move upward. At the same time, the driving plate 704 drives the noise reduction frame 3 to slide upward on the outer surface of the slide rail 11, and the noise reduction frame 3 drives the buffer pad 5 to move upward away from the bottom of the inner cavity of the L-shaped plate 1, so that the engraving and milling machine body 2 moves out of the inner cavity of the noise reduction frame 3, thereby releasing the noise reduction protection of the engraving and milling machine body 2, making it convenient for the staff to perform maintenance on it, or take out the parts. The device is simple to operate and convenient for noise reduction maintenance, thereby meeting the customer's usage needs.
