Description

technical field [0001] The invention relates to a processing technology of a curvature radius template of an outer spherical ball bearing and a clamping device thereof. Background technique [0002] When the outer spherical ball bearing is produced, because its outer diameter is a spherical shape, it is necessary to test the spherical surface before leaving the factory to check whether the spherical surface meets the requirements, so as to ensure that the products that meet the requirements flow into the market and ensure that consumers can rest assured. Use, while improving the reputation of the manufacturer. Existing methods of testing whether the spherical surface of the outer spherical ball bearing meets the requirements generally use the light gap method. When measuring, the curvature radius sample is buckled on the spherical surface, and the light leakage between the spherical surface and the curved surface of the sample is observed to determine the degree of agreement...

AI Technical Summary

Problems solved by technology

The current radius of curvature template generally makes a ring first, grinds the inner hole according to the curvature radius of the template, and then cuts it out in pieces. The current sample can only be processed into a circular arc surface on one side. Upper and lower curvature templates cannot be made together

Once the inner hole of the ring is worn too large, it will only be scrapped, and it is difficult to process to the required dimensional accuracy of the radius of curvature
