Description

Jumping controller for generator shaft of new energy passenger car Technical Field The invention belongs to the technical field of motor shaft detection equipment, and particularly relates to a runout controller for a motor shaft of a new energy passenger car. Background The new energy passenger car generator shaft is a motor shaft applied to a new energy car, and the new energy passenger car generator shaft is required to have the characteristics of high precision, high stability, high reliability and the like, and the performance of the new energy passenger car generator shaft directly influences the running efficiency and the stability of the motor. Therefore, it is important to detect the quality of the motor shaft. The traditional motor shaft detection technology mainly comprises methods of manual detection, optical detection and the like, but the methods have certain limitations in practical application. In order to improve the detection efficiency and accuracy of the motor shaft, research and development of motor shaft detection devices have become urgent. However, the current motor shaft detection detector still has some problems, and improvement is needed. First, the existing detection device has a relatively single function, and usually only detects specific performance parameters. For example, some detection devices can only measure radial runout of the motor shaft, and cannot detect other parameters such as surface flatness of the motor shaft. This results in multiple devices being required to perform the detection of different performance parameters during the detection process, respectively, increasing production costs and detection time. Secondly, in order to improve detection efficiency, the conventional detection device usually only detects the runout tolerance of a single section when detecting the runout, and the detection effect of the method is poor. Because the motor shaft can have the phenomenon that the runout tolerance of a plurality of sections exceeds standard in the processing process, the detection result of a single section cannot comprehensively reflect the overall performance of the motor shaft, so that some unqualified motor shafts are misjudged as qualified products. Third, in the existing motor shaft detection device, the motor shaft is usually driven by a motor to rotate for detection, but vibration generated by motor operation can have a certain influence on the detection result. Vibration may cause an increase in detection error and even an unstable detection result, thereby reducing accuracy and reliability of the detection device. Finally, the motor shaft after detection is required to be distinguished and placed manually according to whether the motor shaft is qualified or not. The labor intensity in the process is high, and human errors are easy to occur. On one hand, operators may misjudge the qualified motor shaft as an unqualified product to cause resource waste, and on the other hand, misjudge the unqualified motor shaft as a qualified product to possibly cause the motor to malfunction and influence the operation efficiency and the safety of the motor. In summary, the current new energy motor shaft detection device has a plurality of problems in terms of functions, detection effects, accuracy, manual operation and the like, and development of a more advanced, more efficient and more accurate detection device is needed to meet the increasingly strict requirements of the new energy motor industry on motor shaft quality detection.

In order to solve the technical problems, the invention is solved by the following technical scheme. The runout controller for the generator shaft of the new energy passenger car comprises a mounting base frame, wherein the mounting base frame is sequentially provided with a rotating mechanism and a detecting mechanism from top to bottom.
