For the automatic processing of sand box for foundry equipment,an intelligent and automatic sand box production line is proposed,including a truss,a reversible servo manipulator,a two-way self-aligning mechanism and several cutting machines in the linear direction along the truss.The pro-duction line has high degree of intelligence and automation,through the servo manipulator,it can realize the grasping and rotating of the sand box workpiece,and it can easily cope with a variety of different sizes of sand box workpieces,and the workpiece centering precision is high.The cutting machine can also meet the vertical and horizontal double-sided machining,greatly improving the production efficiency.
