Edge grinding device for steel structure metal plate

The utility model belongs to the technical field of edge grinding, and particularly relates to an edge grinding device for a steel structure metal plate. A feeding hole is formed in the top of the operation table; a plurality of electric telescopic rods are fixedly connected to the two opposite faces of the top of the operation table. The plurality of electric telescopic rods are symmetrically arranged and are equivalently distributed at the top of the operation table; the output ends of the multiple electric telescopic rods are fixedly connected with sliding blocks. By means of the structure, the multiple electric telescopic rods can drive the sliding block to move, so that the two grinding devices are driven to move, the device is suitable for metal plates of different sizes, the tedious step that different grinding devices need to be replaced for the metal plates of the same size is reduced, and the working efficiency is improved. And meanwhile, the multiple brushes are driven to move through movement of t
