Technical field

The utility model relates to a clamp for grinding a cylinder, belonging to the technical field of clamps.

Background technique

A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools and free abrasives such as whetstones and abrasive belts, such as honing machines, super-finishing machine tools, abrasive belt grinders, grinders and polishing machines. Machine etc.

Existing grinders often need to be fixed on the feed component when processing workpieces. Through the movement of the feed component and the rotation of the grinding wheel, the workpiece is ground. Generally, ideal fixation can be achieved for larger workpieces. The grinding effect is good, but when it is necessary to grind a smaller diameter cylinder, the fixed fixture cannot adapt. When the fixture is clamped to the extreme position, it cannot contact the outer surface of the small diameter cylinder, or it can make contact, but it is not firmly fixed, resulting in Cannot be processed normally.
