[0002] A spherical base grinder is used for grinding the spherical base of tapered rollers, and can perform the processing of spherical surfaces. The production of spherical bases can be achieved by grinding a cylinder with a grinding tool.
[0003] When the existing spherical base grinder performs spherical surface processing, it is necessary to fix the cylinder. The grinding tool continuously cuts around the cylinder to gradually form a spherical surface. Multiple balls can be produced from one cylinder.

Since the clamping jaws are mostly fixedly installed on the grinder and cannot be adjusted in distance, when grinding a single cylinder, it is necessary to frequently clamp and loosen to adjust the length of the cylinder to adapt to the distance of the grinding tool, resulting in inconvenient processing. In view of this, a mechanical clamping part for a spherical base grinder is now proposed. Summary of the Utility Model
