Abstract
The utility model relates to an anti-explosive grinding machine and belongs to the technical field of a grinding machine structure. The anti-explosive grinding machine comprises a work bench, a grinding wheel, a grinding wheel chuck, a main shaft and an outer anti-explosive shield with an opening and further comprises a rotating shield of an inner anti-explosive shield. The rotating shield of the inner anti-explosive shield is arranged between the grinding wheel and the outer anti-explosive shield; when fragments are caused by the grinding wheel, the fragments are blocked by the rotating shield of the inner anti-explosive shield; impact of the fragments to the rotating shield of the inner anti-explosive shield first separates the rotating shield of the inner anti-explosive shield from the outer anti-explosive shield and then the opening of the outer anti-explosive shield is closed by the rotating shield of the inner anti-explosive shield; and meanwhile, a switch positioning plate is separated from a travel switch by the rotating shield of the inner anti-explosive shield, so that power supply of the grinding machine is cut off. By the use of the anti-explosive grinding machine, the fragments generated by the grinding wheel can not only be prevented from fly out, but the opening of the outer anti-explosive shield is closed; and the power supply of the grinding machine is cut off, so that damage is further prevented.
