This invention relates to an in-situ detection device and method for the wear state of a grinding wheel. The device includes a grinding wheel, an optical camera, and a camera bracket. The optical camera is fixed on the camera bracket, which is mounted on a machine tool and can move laterally, longitudinally, and vertically, as well as adjust the shooting angle. The lateral movement direction is perpendicular to the end face of the grinding wheel. The in-situ detection method for the wear state of a grinding wheel of this invention involves: firstly, using the optical camera to capture the three-dimensional microstructure of the grinding wheel; then, after image processing, obtaining a digitized three-dimensional microstructure of the grinding wheel; next, based on the interference depth between the abrasive grains of the grinding wheel and the workpiece under actual processing conditions, extracting a two-dimensional image of the grinding wheel surface at a specific depth; calculating the fractal dimension of the two-dimensional image based on fractal theory; and finally, determining the wear state of the grinding wheel by using the calculated fractal dimension of the grinding wheel surface.

The utility model discloses a mechanism for improving three-proofing paint pollution, which comprises a protective plate and a spraying area for positioning a main board, a locking component is arranged in a non-spraying area of the protective plate, and an expansion end of the locking component is arranged on the side surface of the spraying area and is matched with the side surface of the main board positioned in the spraying area. The extrusion pieces of the locking assembly are located at the two ends of the side face of the spraying area, the expansion ends of the extrusion pieces are only in contact with the side face of the main board, the movement path of the paint spraying head is prevented from being shielded, it is ensured that the paint spraying head can completely cover all the areas of the main board, and therefore spraying uniformity and integrity are improved.
