Description

Technical Field

[0001] The present invention relates to the technical field of rotor detection auxiliary devices for motor production, and in particular to a rotor detection auxiliary device for motor production. Background Art

[0002] A machine refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor is represented by the letter M in the circuit. Its main function is to generate driving torque. As the power source of electrical appliances or various machines, the generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy. Motors are currently needed in many fields. Motors play a very important role in life and production. The motor is mainly composed of a stator and a rotor. When manufacturing a motor, the rotor is usually tested. In the past, when measuring the specifications of the rotor, it was usually measured manually to ensure that the rotor specifications meet the requirements;

[0003] The existing Chinese patent CN 216414129 U discloses a rotor detection auxiliary device for motor production. In the process of detecting the rotation of the rotor, each pressing plate is tightly attached to the side wall of the inner ring of the rotor under the action of centrifugal force, and each sliding rod extends out of the positioning groove to the same length, so as to ensure that the rotor and the positioning plate are in a concentric state, thereby avoiding the problem of rotation axis deviation and ensuring the accuracy of the detection result.

[0004] However, although the pressure plates in the above-mentioned rotor detection auxiliary device for motor production will be tightly attached to the side walls of the inner ring of the rotor under the action of centrifugal force, the weight of the rotor itself mainly acts on the topmost pressure plates and the pressure plates on both sides. Therefore, the downward force on these three pressure plates is much greater than that on the three pressure plates below. Therefore, the sliding rods connected to these three pressure plates will squeeze the springs inward, and it is impossible to ensure that all sliding rods extend to the same length, that is, it is impossible to ensure that the rotor and the positioning plate are in a concentric state.
