Description

Technical Field

[0001] The utility model relates to the field of production and processing of bearing inspection tooling, in particular to an inspection tooling for quickly turning over bearings. Background Art

[0002] Bearing inspection mainly includes the following aspects:

[0003] Appearance inspection: Under a diffuse light, carefully observe the bearing's appearance, raw material cracks, forging cracks, heat treatment cracks, and grinding cracks. At the same time, check whether the bearing has mechanical scratches such as wear, scratches, crushing, and bumps, as well as defects such as rust, black skin, and pitting. These will affect the service life and work safety of the bearing.

[0004] Radial clearance inspection: Except for bearings with pre-interference, radial clearance should be inspected. Deep groove ball bearings can be inspected by hand rotation, and it is better to be smooth and flexible, without vibration and left and right swing. Cylindrical roller and spherical roller bearings can be inspected with a feeler gauge. Insert the feeler gauge between the roller and the bearing ring. The insertion depth of the feeler gauge should be greater than 1 / 2 of the roller length. When the radial clearance of the bearing cannot be measured with a feeler gauge, the axial movement of the bearing can be measured instead of the reduction in radial clearance.

[0005] Check the tightness between the bearing and the shaft shoulder: Generally, the bearing installed with tight fit interference fit must be close to the shaft shoulder. The main inspection methods are the lighting method and the thickness gauge inspection method. The lighting method is to aim the electric light at the bearing and the shaft shoulder to see the light leakage. The thickness gauge inspection method is to use a thickness gauge to check the clearance between the bearing and the shaft shoulder.

[0006] Manually flipping bearings one by one may result in missed or over-flipped bearings, leading to the risk of missed inspections during the bearing appearance inspection process. At the same time, manual flipping involves repetitive actions, low work efficiency, and increased fatigue for operators.

[0007] In view of this, the inventor wants to design a testing tool for quickly flipping bearings. Utility Model Content
