Rolling bearing is a precise component in mechanical equipment, and also a basic component with strong versatility. Most mechanical equipment that need to be rotated cannot be separated from the application of bearings. Scientific manufacturing and production are gradually developing in the direction of high, precision and sharpness, and new requirements are gradually put forward for the performance, service life, reliability and economic indicators of mechanical equipment,
Bearing often needs mass production, so the inspection of bearing is very important for the bearing manufacturing industry. It can ensure the normal production of bearing and control the quality of bearing products, and is a means to ensure that the bearing reaches various grade standards. It usually includes inspection of bearing dimension and geometric accuracy, form and position tolerance and bearing surface quality.
In the bearing production process, inspectors usually account for about 10%~16% of the production workers.
The role of the bearing inspection process mainly includes three aspects:
First, check the product quality. Strict inspection can ensure the qualification rate of bearing;
Second, monitor product quality. Supervise the processing process to prevent quality accidents;
Third, when an accident occurs, report it level by level in time.
The inspection items of bearing include:
Use of bearing inspection meter, process adjustment technology, bearing quality analysis, etc. Inspectors are required to:
A. Be able to understand the process documents, and be familiar with the procedures and reference methods of production inspection;
B. Be able to correctly select, adjust and maintain measuring tools and instruments;
C. Master the inspection method;
D. Have certain fault analysis ability.
