The invention discloses stainless steel plate deburring equipment for a high-voltage switch cabinet, and particularly relates to the technical field of high-voltage switch cabinet machining. An upper grinding roller, a lower grinding roller and grinding paper make contact with the cutting section of a stainless steel plate, and the grinding paper grinds the section of the stainless steel plate; the upper grinding roller and the lower grinding roller are driven by the driven shaft to grind the section of the stainless steel plate, grinding of the upper surface, the lower surface and the side surface of the stainless steel plate is achieved, the deburring effect is guaranteed, the grinding efficiency is improved, meanwhile, the grinding rollers and the supporting frame are designed to be of a detachable structure, the guide blocks enter the guide grooves, and the grinding efficiency is improved. The synchronous transmission of the grinding roller and the driven shaft is realized; the grinding mechanism is matched with the sliding table to slide on the linear guide rail, drives the supporting column to move in the same direction and drives the upper grinding roller, the lower grinding roller and the grinding paper in the grinding mechanism to do reciprocating linear motion on the section of the stainless steel plate, the grinding automation degree is improved, and the efficiency is high.
