Grinding wheel clamping mechanism and grinding wheel finishing device using clamping mechanism

Abstract

The invention relates to a grinding wheel clamping mechanism and a grinding wheel finishing device using the clamping mechanism for solving the problem of higher vibration impact on a grinding wheel during finishing in the prior art. In the grinding wheel clamping mechanism, a grinding wheel to be finished coats a connecting shaft section of a workpiece main shaft in a peripheral rotation stopping and axial floating manner by a clamping head, so that the grinding wheel to be finished can be in floating contact with a grinding surface of a grinding disc under the gravity effect of self and the clamping head after the grinding wheel clamping mechanism moves onto the grinding disc. The constant-pressure grinding is used for replacing the constant-position feeding grinding in the prior art, so that the contact of the surface of the grinding wheel to be finished with the grinding surface always adopts a convex part of the to-be-finished surface of the grinding wheel, the impact force suffered by the grinding wheel and the removing nonuniformity of materials on the surface of the grinding wheel caused by the impact force are largely reduced, flanges, burrs and breaches on the outer edge of the grinding wheel can be effectively reduced, and the flatness of the to-be-finished surface of the grinding wheel and the edge sharpness are improved.

Description

technical field [0001] The invention relates to a grinding wheel clamping mechanism and a grinding wheel dressing device using the clamping mechanism. Background technique [0002] The grinding wheel of the present invention is a diamond grinding wheel for profile grinding, specifically a V-shaped grinding wheel, which is used for precision machining of V-shaped positioning grooves. The main characteristics of this type of grinding wheel are thin thickness (thickness is generally 0.2-5mm), narrow ring width (5-20mm), and V-shaped angle of the tip of 30-120°, which is difficult to process. Dressing of such grinding wheels is usually carried out using a grinding machine. During the dressing process, first clamp the diamond grinding wheel to be trimmed on the workpiece spindle at a set angle, and make the diamond grinding wheel rotate with the workpiece spindle, and then feed the high-speed rotating grinding disc (that is, the tool wheel) on the grinding machine. The bevel of...
