The invention discloses a three-degree-of-freedom self-adaptive flexible gripper for a sorting robot. The three-degree-of-freedom self-adaptive flexible gripper comprises a support, a driving branch chain, a driven branch chain and a self-adaptive clamping belt. The self-adaptive clamping belt is driven by the four driving branch chains to grab or release a casting, the robot can be regarded as a parallel mechanism with at most three motion freedom degrees of spatial two-translation and one-rotation, and the motion freedom degrees are multiple; the self-adaptive clamping belt can be well attached to the surface of a grabbed casting, the contact area is large, self-adaptive grabbing is achieved, and the casting can be prevented from being damaged in the grabbing process; the clamping cylinders and the self-adaptive clamping belts can be replaced according to the needs of grabbed objects, and the adaptability to the surface shapes of the grabbed castings and other objects is high. And the grabbing and sorting r
