Description

Technical Field

[0001] This utility model relates to the field of bearing dust cover manufacturing, specifically to a tooling for detecting the flatness of the working surface of a capping machine. Background Technology

[0002] In the bearing manufacturing process, the press-fitting of the dust cover is a crucial step. However, if the flatness of the supporting surface is not good, it can cause a series of problems.

[0003] When the supporting surface is uneven, the bearing dust cover is prone to tilting during press-fitting. This tilting not only affects the uniformity of press-fitting but may also lead to a decrease in the sealing performance between the dust cover and the bearing. Poor sealing will further affect the service life and performance of the bearing, as dust and contaminants can more easily enter the bearing, accelerating its wear.

[0004] Uneven pressing can also cause the dust cover to deform or crack. This not only damages the product's appearance but may also affect its normal function. In severe cases, it can even lead to the complete failure of the bearing, posing a safety hazard to the entire mechanical system.

[0005] To ensure press-fit quality, the flatness of the support surfaces must be strictly controlled during the production process. This can be achieved by using high-precision measuring tools and equipment to ensure that each support surface meets the specified flatness requirements. Utility Model Content

[0022] Existing flatness measurement techniques mainly involve:
