[0002] The traditional power sensor inner ring magnetic steel press-fitting mode is that the magnetic steel is pressed into the power sensor inner ring placed in the special base by the hand press machine and the special press rod in sequence. This press-fitting mode has the following defects: 1. Since it is a manual operation, the operation process is relatively complicated, and it is difficult to control the consistency of the magnetic steel state. 2. The hand press machine press-fitting operation requires two hands to coordinate, the left hand sends the magnetic steel while rotating the special base, and the right hand operates the press rod to press the magnetic steel in sequence. The operator needs to coordinate the actions of both hands, otherwise there will be a risk of misoperation such as the magnetic steel cannot be pressed into the corresponding hole or the magnetic steel is cracked; all operators must be trained until both hands can coordinate the actions to be able to work. 3. Due to the structure limitation of the hand press machine and the special press rod, after the magnetic steel is pressed into the power sensor inner ring, the surface of the magnetic steel can only be flush with the surface of the magnetic steel slot of the power sensor inner ring, and the magnetic steel cannot be completely embedded in the magnetic steel slot of the power sensor inner ring; the magnetic steel has the risk of loosening in subsequent use. 4. Due to the influence of visual fatigue, the speed limitation of the hand press, and irregular misoperation, in the mass production line, this post is a bottleneck for improving efficiency. SUMMARY
