Description

technical field [0001] The invention belongs to the technical field of bearing testing equipment, and in particular relates to an automatic detection device for roundness of a bearing inner ring and a use method thereof. Background technique [0002] In the bearing manufacturing industry, the degree of automation of processing is relatively high, and the bearing parts can be automatically completed by special processing equipment from loading, processing, testing to unloading. Rolling bearings are highly interchangeable standard components and are important supporting parts for transmission motion and load bearing in various machinery. The inner ring of the bearing is a part in close contact with the shaft. It not only has dimensional errors, but also has roundness errors (macroscopic errors, which are low-frequency signals), which affect the performance and life of bearing products. The current detection is still completed by manual operation, the degree of automation is s...

AI Technical Summary

Problems solved by technology

The inner ring of the bearing is a part that is in close contact with the shaft. It not only has dimensional errors, but also has roundness errors (macroscopic errors, which are low-frequency signals), which affect the performance and life of bearing products.

The current detection is still done manually, the degree of automation is still relatively low, and the labor intensity of workers is high.
