[0022] In the implementation of this example, the noise reduction structure includes a mounting frame 51 fixedly mounted on the top of the vertical control console 2, a threaded rod 52 with one end penetrating through and extending to the outside of the mounting frame 51 is rotatably mounted on the bevel grinder 1, and a support assembly 53 for supporting the rotation of the threaded rod 52 is arranged inside the mounting frame 51, and the support assembly 53 includes a bearing and a circular groove, the circular groove is opened on the top of the mounting frame 51, the bearing is fixedly mounted on the inner circumferential wall of the circular groove, and the inner circumferential wall of the bearing is fixedly connected to the outer surface of the threaded rod 52, so as to support the rotation of the threaded rod 52, and the outer surface of the threaded rod 52 A connector 54 is threadedly connected, and a noise reduction frame 55 for isolating noise is fixedly installed on one side of the connector 54, so as to cover the part fixing seat 3 and the turning tool mounting seat 4. The noise reduction frame 55 includes a soundproof cover and soundproof glass. A mounting groove is provided on the front of the soundproof cover, and the soundproof glass is fixedly installed inside the mounting groove.

A guide component 56 is provided on the twill grinder 1 for limiting the up and down movement trajectory of the noise reduction frame 55, so as to limit the up and down movement trajectory of the noise reduction frame 55.

[0023] Among them, the guide assembly 56 includes a limit bar and a guide groove. The limit bar is fixedly installed on the twill grinder 1, and the guide groove is opened on the back of the noise reduction frame 55. The inner wall of the guide groove is slidably connected to the outer surface of the limit bar, so as to limit the noise reduction frame 55 to move left and right only on the outer surface of the limit bar.

[0024] By adopting the above technical solution, the rotation of the threaded rod 52 is controlled, and then the connecting piece 54 threadedly connected to the outer surface of the threaded rod 52 drives the noise reduction frame 55 to move, thereby controlling the outer surface of the limit strip of the noise reduction frame 55 on the guide assembly 56 to move downward until the noise reduction frame 55 covers the part fixing seat 3 and the turning tool mounting seat 4, thereby utilizing the noise reduction frame 55 to isolate the noise caused by the turning parts.
