Description

Technical Field

[0001] This utility model relates to the field of bearing ball size detection technology, and specifically to a size detection mechanism for manufacturing silicon nitride bearing balls. Background Technology

[0002] Silicon nitride bearing balls are ceramic bearing balls made primarily of silicon nitride. They possess characteristics such as high hardness, high temperature resistance, and low density, and are widely used in precision machinery, new energy vehicles, aerospace, and other fields.

[0003] After the bearing balls are manufactured, they need to be dimensionally inspected to ensure that the produced bearing balls meet the standards. The inspection is usually done by sampling. During the inspection, a bearing ball is randomly selected and then inspected using tools such as a dial indicator. Multiple measurements are required to take the average value, which increases the inspection time, reduces the inspection efficiency, and makes it difficult to adapt to the requirements of high-precision scenarios.
