Edge grinding device for color steel plate machining

The utility model discloses an edge grinding device for processing a color steel plate, which comprises two side plates, bearings are fixedly embedded on the side plates, a support shaft is in interference fit with the bearings, a first motor is fixed on the side plates, a rotating shaft of the first motor is fixed with the support shaft through a coupler, a base is fixed on the support shaft, and connecting plates are mounted on two sides of the base. A plate frame is fixed between the two connecting plates, a grinding plate is fixed to the plate frame, the lower end of the side plate is fixed to a piston rod of a cylinder body, and a supporting plate is fixed to the lower end of the cylinder body. By means of reciprocating movement of the grinding plate and forward and backward movement of the grinding plate, stable reciprocating grinding can be achieved when the grinding plate grinds the side edge of a steel plate, and by means of rotation of the grinding plate, the requirement for attached contact grindin
