Product features: This welding robot adopts a reinforced reducer with a large reduction ratio design to improve control accuracy. The 4-axis adopts hollow structure replaces the traditional structure with double angular contact bearings to improve joint support stiffness; the 4-axis and 6-axis are equipped with special gear gap adjustment structure, higher joint accuracy. The wrist is changed to a U-shaped structure to increase the stiffness. The wrist is shortened to improve flexibility. The special wrist noise reduction structure reduces running noise.
