Along with the development of technique, the range of application of motor is wider and wider more, and the motor includes stator and rotor, and the stator has the coil, and the rotor has the magnet steel part, and when electric current passed through the coil, the coil can produce the magnetic field, and under the effect in magnetic field, the magnet steel part can drive the rotor and rotate for the stator to the output shaft that drives the motor rotates. As shown in fig. 1, the motor rotor 1 includes a main body portion 11, the main body portion 11 has a through hole 12 and a recessed portion, and the through hole 12 has an effect of reducing the mass of the main body portion 11. The magnetic steel component 13 is disposed in the recessed portion, and in a normal case, the magnetic steel component 13 is only inserted into the recessed portion, that is, the magnetic steel component 13 is movably mounted in the recessed portion, so that the magnetic steel component 13 is easily separated from the main body 11 during the transportation of the motor rotor 1, and the rotor cannot be driven by the magnetic field generated by the coil of the stator, and further the motor cannot normally operate.

In view of this, the embodiment of the present application provides a clamping assembly 2 and a conveying apparatus, which are used for clamping a motor rotor 1, and the structure of the motor rotor 1 can refer to fig. 1, and reduces the possibility that the magnetic steel component 13 of the motor rotor 1 falls off from the main body 11 during the movement process.

As shown in fig. 2, the embodiment of the present application provides a clamping assembly 2, and the specific structure is as shown in fig. 3, where the clamping assembly 2 includes a mounting portion 21, an abutting portion 22, and a magnetic component 23, the abutting portion 22 and the magnetic component 23 are mounted on the mounting portion 21, and the magnetic component 23 is used for magnetically adsorbing the magnetic steel component 13.

Taking the example that the driving part 24 only drives the first abutting part 221 to move, at least a part of the abutting part 22 extends into the through hole 12 of the motor rotor 1, the driving part 24 drives the first abutting part 221 to move away from the second abutting part 222, after the first abutting part 221 contacts with the inner wall of the through hole 12, the driving part 24 continues to drive the first abutting part 221 to move, the first abutting part 221 drives the motor rotor 1 to move along the direction that the first abutting part 221 moves away from the second abutting part 222, because at least a part of the second abutting part 222 is located in the through hole 12, after the first abutting part 221 drives the motor rotor 1 to move for a certain distance, the second abutting part 222 can abut against the inner wall of the through hole 12.
