Technical Field

[0001] The utility model relates to the technical field of bearing detection, in particular to an automatic bearing inner diameter bulge detection machine with high efficiency. Background Technique

[0002] There are thousands of automotive parts. In recent years, in order to maximize economic benefits, the streamlining of automotive parts has become a trend, which necessarily requires achieving this goal by canceling the connectors between parts or modifying the assembly methods between parts.

[0003] In the prior art, the automotive industry has extremely strict requirements for product quality, especially for the defined safety parts, requiring "zero defects". For mass-produced products, this is undoubtedly a huge challenge. In the case where 100% full inspection of outgoing products cannot be achieved, only the dimensional tolerances of product production can be tightened and the sampling frequency during the production process can be increased; currently, the inspection of the bulge amount of the inner diameter of such bearings is usually measured by a profilometer or a special gauge.

[0004] However, there are high requirements for the storage environment, temperature, and humidity of the profilometer, and the above detection methods all require manual operation, which has limitations in terms of skills and personnel arrangements, with low detection efficiency and the inability to ensure 100% product qualification, so there is a certain risk for the quality of outgoing products.
