The invention relates to the field of robots, in particular to a multifunctional palletizing robot based on a Stewart parallel connection platform. The multifunctional palletizing robot comprises caterpillar band travelling mechanisms, a chassis, a rotating table, fine tuning tables, fine tuning air cylinders, mechanical arms, gripping devices and gripping hands; the caterpillar band travelling mechanisms are located on the two sides of the chassis, the rotating table is located in the middle portion of the chassis, the fine tuning tables are located at the upper end of the rotating table, the fine tuning air cylinders are located between the rotating table and the fine tuning tables, the mechanical arms are located at the upper ends of the fine tuning tables, and the gripping devices are located at the ends of the mechanical arms; the rotating table, the fine tuning air cylinders and the fine tuning tables form the Stewart parallel connection platform; and the number of the mechanical arms is three, the number of the gripping devices is three, and the three gripping devices are installed on the three mechanical arms. The multifunctional palletizing robot is high in palletizing efficiency, manual gripping hand replacement is replaced, and the labor intensity of workers is reduced; and in addition, the accuracy for replacing the gripping hands, gripping objects and palletizing the objects is high, and damage to the objects is greatly reduced.
