Steel plate positioning and machining equipment for shipbuilding

According to the steel plate positioning and machining equipment for shipbuilding, when the equipment works, a pull ring is pulled firstly, then a limiting rod is separated from a limiting groove, the equipment is rotated, then steel plates in different directions are fed, the convenience of the equipment is greatly improved, and the working efficiency is improved. Then the distance between the first supporting plate and the second supporting plate is adjusted according to steel plates of different sizes through rotation of a double-shaft driving motor, then the steel plates are placed on a clamping movable plate, then the steel plates are stably clamped through rotation of a positioning driving motor, and then the steel plates are stably clamped through rotation of an adjusting air cylinder; and then the adjusting rack is driven to move, so that the steel plate is turned over, finally, stable clamping and rapid turning over of the steel plate are achieved, and the machining quality of the steel plate is grea
