[0025] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a filtering device for a numerically controlled machine tool. The swing filtering structure 4 includes a machine box 41, which is fixed to the right end of the bottom end surface of the liquid guide frame 3 by bolts. A rotating disk 42 rotatably connected to the machine box 41 is installed at the front end of the machine box 41, and the rear end of the rotating disk 42 is connected to the output shaft of a motor 45 installed inside the machine box 41, so that the rotating disk 42 is driven by the motor 45. A rotating rod 43 is integrally formed on the front surface of the rotating disk 42, and a slide plate 44 connected to the rotating rod 43 is formed inside the slide plate 44. The rotating rod 43 slides inside the slide plate 44. A mounting frame 46 is integrally formed at the left end of the slide plate 44, and a reinforcing rib 441 is integrally formed at the connection between the slide plate 44 and the mounting frame 46. The reinforcing rib 441 is respectively located at the front and rear ends of the slide plate 44 to reinforce the connection between the slide plate 44 and the mounting frame 46.

[0026] The mounting frame 46 is provided with a mounting groove 47 inside, and a clamping block 48 is integrally formed at the upper and lower ends inside the mounting groove 47, and a mounting block 49 is connected to the mounting groove 47. At the same time, the mounting block 49 will be spliced ​​with the clamping block 48. The mounting block 49 is arranged on the surface of the filter frame 410. The left and right surfaces of the filter frame 410 are both provided with mounting blocks 49. The mounting blocks 49 at both ends have the same structure. The mounting blocks 49 at both ends are provided with matching mounting frames 46. The slide plate 44 arranged on the left end mounting frame 46 slides along the inner wall of the fixed frame 411, and the fixed frame 411 is arranged at the bottom of the liquid guide frame 3;

[0027] The inside of the machine box 41 is equipped with auxiliary clamping wheels 401, which are located at the upper and lower ends of the machine box 41, and the slide plate 44 is located between the upper and lower ends of the auxiliary clamping wheels 401, which can improve the sliding stability and flexibility of the slide plate 44;

[0028] The installation frame 46 is provided with a spring 412 inside. Two springs 412 can be provided, respectively, at the front and rear ends of the installation frame 46, or three springs 412 can be provided, respectively, at the middle part and the front and rear ends of the installation frame 46. A clamping head 413 slidably connected to the installation frame 46 is fixed at the end of the spring 412. The clamping head 413 is connected to the clamping groove 414 provided on the installation block 49, and is used to clamp the installation block 49 when the installation block 49 is inserted into the installation groove 47, so that the installation block 49 will not slide easily.
