Description

Technical Field

[0001] This utility model relates to the field of measuring instrument design and manufacturing technology, and in particular to a mechanical measuring device for the roundness of motor rotors. Background Technology

[0002] In the process of motor production and maintenance, rotor roundness is a key indicator affecting the stability, service life and energy efficiency of motor operation. Therefore, it is crucial to measure it accurately. However, traditional mechanical measuring devices for motor rotor roundness generally suffer from low automation. The position adjustment of the sensing unit and the fixing of the rotor rely heavily on manual operation, which is not only labor-intensive and inefficient, but also prone to affecting the measurement accuracy due to human error.

[0003] In existing technologies, such measuring devices often suffer from low automation. The adjustment of the sensor unit position and the fixing of the measured object rely heavily on manual operation, which is not only time-consuming and labor-intensive, but also difficult to adapt to the measurement needs of different sized objects. The devices are not versatile and efficient. At the same time, the space utilization of the devices is unreasonable. The lack of a dedicated storage structure leads to messy storage of tools and accessories. There is also no material receiving component, which makes it easy for materials or waste to fall during the measurement process to scatter and pollute the working environment. The devices are not practical and environmentally friendly. Utility Model Content
