[0002] With the rapid development of the wind power industry, the demand for wind power bearings, which are a key link in the industry, is also growing continuously. Bearings occupy an important position in industrial basic components, and dedicated bearing instruments are the key to ensuring bearing quality. Practice has proved that the contour curve of the roller surface can effectively reduce and eliminate stress concentration. Therefore, it is particularly important to control the curve specification of the roller processing process.

[0003] Measuring instruments play an indispensable role in quality monitoring during the production process. They are like the "eyes" in process production, constantly monitoring and transmitting real-time production conditions to ensure the stability of product quality. In the past roller production, the method of detecting the roller surface profile curve value was to send it to the metrology room for detection using a special profiler. However, since multiple processing grinders are started and sent for inspection at the same time, each specification needs to wait for 20-30 minutes, resulting in a lot of waiting time wasted. In addition, due to the threshing of the grinding wheel during the roller grinding process, the curve deformation exceeds the process specifications, and there is a lack of effective real-time detection instruments and monitoring measures between processes. It is necessary to frequently go to the metrology room for testing, which makes the metrology room heavy and seriously slows down the production progress. To this end, we propose a logarithmic roller surface profiler. Utility Model Content
