Abstract
The invention relates to an anti-explosion grinding machine and an anti-explosion method thereof, and belongs to the technical field of grinding machine structures. A grinding wheel is mounted on an anti-explosion outer shield through an inner anti-explosion rotary shield; the inner anti-explosion rotary shield is provided with a fan-shaped actuation disk surface corresponding to the opening of the anti-explosion outer shield, so that when the grinding wheel in the working state bursts, the inner anti-explosion rotary shield is separated from the anti-explosion outer shield under the effect of tangential force, stressed on the fan-shaped actuation disk surface, of fragments formed when the grinding wheel bursts, and does rotational movement around a main shaft of the grinding wheel, until the fan-shaped actuation disk surface is opposite to the position of the opening of the anti-explosion outer shield, the fan-shaped actuation disk closes the opening of the anti-explosion outer shield to complete the anti-explosion treatment in grinding wheel bursting; meanwhile, when the inner anti-explosion rotary shield does rotational movement, the rotational movement of the main shaft of the grinding wheel is stopped. The anti-explosion grinding machine and the anti-explosion method can not only stop the fragments of the grinding wheel from flying off, but also close the opening of the anti-explosion outer shield, and meanwhile, the power supply of the grinding machine is turned off to prevent further expansion of the harm.
