[0002] A grinding wheel dresser is a specialized machine tool accessory used on manual surface grinders, universal tool grinders, and various surface and profile grinders to dress grinding wheels with various cross-sections composed of straight lines and arcs. When used in conjunction with gauge blocks, a grinding wheel dresser can achieve the desired convex and concave angles on precision grinding wheels. Thickness dressers and synchronous grinding wheel dressers can dress the thickness and sides of grinding wheels. The inherent design of the grinding wheel dresser allows for extremely precise dimensional adjustments.

[0003] A typical grinding wheel dressing mechanism consists of a swing plate, a right-angle seat, and a handle. It holds the diamond tool and swings it back and forth during grinding wheel dressing.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs.When there is a conflict, the definition in the specification prevails.

[0028] Grinding wheels are the most widely used type of abrasive, capable of rough grinding, semi-finishing, and finishing various surfaces of metals and non-metals, such as outer circles, planes, and worm gear curved surfaces, as well as grooving and cutting. After a period of use, grinding wheels become dull, necessitating dressing to restore their grinding performance and correct geometry. For a worm gear grinding machine, the grinding point of the grinding wheel must be aligned with the axis of rotation of the spindle and the grinding wheel. However, current grinding wheel dressing devices often rely on spring force during spindle movement, frequently resulting in inaccurate wheel positioning, inability to accurately position the wheel after movement, or insufficient positioning rigidity. This leads to low dressing accuracy or failure to achieve the desired geometry during grinding wheel dressing.
