Ship component double-face grinding workbench

The invention discloses a double-sided polishing workbench for ship components, relates to the technical field of ship component processing equipment, and solves the problems that the labor intensity of staff is increased and the safety coefficient cannot be guaranteed due to the fact that a crane is used for turning over to polish an edge on the other side after a single-sided edge on the ground is polished by manual operation. Comprising a feeding line, a plurality of polishing work stations are arranged on the feeding line, the feeding line comprises a first stockline and a second stockline, a feeding trolley is arranged between the first stockline and the second stockline, the feeding trolley reciprocates between the first stockline and the second stockline and passes through a turnover device, and the turnover device comprises a base and a turnover frame. A feeding port is formed in the side, close to the feeding trolley, of the overturning frame, and the base abuts against the periphery of the overturni
