The utility model discloses a motor rotor shaft turning clamp that can be self-adaptive and tightly hold and flexibly position, relates to the field of machining, and is composed of Morse taper, external thread connecting shaft, spring collet, threaded sleeve and adjusting sleeve and other components for connecting with the main shaft of machine tool. The sliding cavity of the front end of the external thread connecting shaft is provided with a sliding sleeve and a telescopic spring, and the sliding sleeve is fixedly connected with the spring collet. The sleeve sleeve of the front end of the threaded sleeve is sleeved outside the spring collet, and the inner wall of the front end is provided with a conical surface that is matched with the conical head of the spring collet. The adjusting sleeve is connected with the threaded sleeve through threads, and can drive the limiting sleeve to push the spring collet to move. During use, rotating the adjusting sleeve makes the spring collet move backward, and the spring collet is tightened under the action of the conical surface, the rotor shaft is self-adaptively and tightly held, and the telescopic spring realizes flexible positioning and compensates for the axial and angular deviation. The clamp can automatically adapt to the rotor shaft with a diameter tolerance within a certain range, has high self-centering precision, is suitable for high-precision turning machining of conventional rotor shafts, and has simple structure and convenient maintenance.
