An installation plate 5 is provided between the two longitudinal bellows 4. The two transverse bellows 3 and the two longitudinal bellows 4 form the overall structure of the bellows, enabling the installation plate 5 to slide up, down, left, and right. When the cover body 1 is installed on the top of the CNC lathe, the cover body composed of the cover body 1 and the top baffle 2 covers the top of the CNC lathe. The processing head and the like are installed and passed through the installation plate 5. A number of through slots 11 are provided on one side of the top baffle 2.

Then, the blowing component 12 is turned on, and the inside of the top baffle 2 is blown through the gooseneck tube 13 and the connecting branch pipes 14 connected to one end of the blowing component 12, so that the dust and chips on the tops of the transverse bellows 3, the longitudinal bellows 4, and the installation plate 5 are blown to one end of the inner cavity of the top baffle 2. After the dust removal is completed, the limit on the top baffle 2 by the limiting components is released, and the top baffle 2 is continuously rotated to turn it over, cleaning the dust and chips on its top. There is no need to remove the protection device, so that this new type can play a dust-proof effect during the processing of the CNC lathe. When regularly cleaning the protective cover, there is no need to remove this device from the CNC lathe, and at the same time, the cleaning effect can be guaranteed, avoiding the accumulation of dust and chips on the top of this device, which may affect the telescoping of the transverse bellows 3 and the longitudinal bellows 4 and cause jams.

[0023] Working principle and usage process of the present utility model: When in use, the cover body 1 is installed on a numerical control lathe, the processing head is connected to the mounting plate 5 and passes through the mounting plate 5. The two transverse bellows covers 3 and the two longitudinal bellows covers 4 form the overall structure of the bellows cover, enabling the mounting plate 5 to slide up, down, left, and right. When cleaning this device, rotate the top baffle 2 by a certain angle, limit the top baffle 2 through the limiting component, and support the top baffle 2 by rotating the support rod 22 so that one end of it abuts against the limiting groove 221 on the top baffle 2. Then, turn on the blowing component 12, and blow air into the interior of the top baffle 2 through the gooseneck tube 13 and the connecting branch pipe 14 connected to one end of the blowing component 12, so that the dust and debris on the transverse bellows cover 3, the longitudinal bellows cover 4, and the top of the mounting plate 5 are blown to one end of the inner cavity of the top baffle 2. After the dust removal is completed, release the limit of the top baffle 2 by the limiting component, continue to rotate the top baffle 2 to make it flip, and clean the dust and debris on its top.
