[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0025] Referring to the accompanying drawings, a grinding wheel with sound warning function is shown, which includes a grinding wheel base 100 and an annular abrasive layer 200 .

[0026] The grinding wheel base 100 adopts a disc-shaped structure. A mounting shaft hole 110 is opened at the center of the grinding wheel base 100. The inner diameter D1 of the mounting shaft hole 110 is 30 mm.

[0027] The annular abrasive layer 200 is disposed on the outer wheel surface of the grinding wheel base 100. The outer diameter D2 of the annular abrasive layer 200 is 100 mm, the ring width W is 5 mm, and the height H is 6 mm.

[0028] At least one sound channel 300 is provided in the grinding wheel base 100, and the two ends of the sound channel 300 are located on one end face 101 of the grinding wheel base 100. When the grinding wheel is in a high-speed rotating state, the high-speed airflow generated on the surface of the grinding wheel makes a sound after passing through the sound channel, so as to remind the operator to pay attention to the high-speed rotating state of the grinding wheel and avoid accidents caused by the operator's accidental touch. In this embodiment, the sound channels 300 are two and are arranged symmetrically with the axis of the grinding wheel base 100 as the center to ensure the dynamic balancing accuracy of the grinding wheel. Of course, the sound channels 300 can also be three or more and are evenly spaced circumferentially arranged on one end face 101 of the grinding wheel base 100.

[0029] The sound channel 300 includes an oblique blind hole 310 and an oblique through hole 320. The oblique blind hole 310 is provided on one end surface 101 of the grinding wheel base 100. The oblique through hole 320 is provided on one end surface 101 of the grinding wheel base 100 and is located on one side of the oblique blind hole 310 and is connected to the oblique blind hole 310. The angle between the axis of the oblique blind hole 310 and one end surface of the grinding wheel base 100 is 45°, and the angle between the axis of the oblique through hole 320 and one end surface of the grinding wheel base 100 is 45°. The inner diameter d1 of the oblique blind hole 310 is greater than the inner diameter d2 of the oblique through hole 320. The inner diameter d1 of the oblique blind hole 310 is 4 mm, and the inner diameter d2 of the oblique through hole 320 is 2 mm, which effectively improves the sound intensity.
