Description

Technical Field

[0001] The utility model relates to the technical field of motor rotor processing, in particular to a clamp for motor rotor processing. Background Art

[0002] The motor rotor is also the rotating part in the motor. The motor consists of two parts, the rotor and the stator. It is a device used to realize the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy. The motor rotor is divided into the motor rotor and the generator rotor. The motor rotor is divided into two types: the inner rotor rotation mode and the outer rotor rotation mode. The inner rotor rotation mode is that the core in the middle of the motor is the rotating body, outputting torque (referring to the motor) or inputting energy (referring to the generator). The outer rotor rotation mode is that the outer body of the motor is the rotating body. Different modes facilitate the application of various occasions.

[0003] During the machining process of the motor rotor, a clamp is usually required to ensure the stability of the machining process. The existing clamps can usually only clamp motor rotors of a single diameter. When the diameter of the motor rotor changes, different clamps need to be replaced, which increases the production cost. In addition, the existing clamps are often unable to rotate the motor rotor. When different surfaces need to be processed, they need to be manually rotated and re-clamped and positioned.

The blocks 7 are close to each other to clamp and fix the end of the motor rotor. The stability of the clamping process is further guaranteed by setting the anti-slip pad, so as to achieve the effect of fixing and clamping the two ends of the motor rotors of different diameters, thereby ensuring the applicability of the fixture and reducing the production cost.
