Uplift type centerless grinding head

Abstract

The invention relates to an uplift type centerless grinding head. A workpiece is clamped through a grinding head clamping device, under the condition that the clamping force is properly controlled, the effect that the workpiece can rotate in the grinding head clamping device when the grinding head works is ensured, a transverse driving mechanism and a longitudinal driving mechanism are adjusted, thus, a grinding wheel of a grinding wheel assembly is tangent to the workpiece, and a rotation mechanism drives the grinding wheel assembly to work, so that the workpiece is ground; when the workpiece is bent or deflected, radial run-out occurs during rotation, the grinding wheel assembly moves synchronously with a balance plate along with the axis of the workpiece under the action of a universal block with the upper surface being a spherical surface, thus, the grinding wheel of the grinding wheel assembly is always kept away from the central axis of the workpiece by a consistent distance, and the ground diameter is kept consistent; and after one section of the workpiece is ground, the transverse driving mechanism and the longitudinal driving mechanism are adjusted, so that the grinding wheel assembly grinds other parts of the workpiece. Centerless grinding with grinding wheel grinding is used for replacing honing, and the problems of difficult grinding and slow honing caused by bending of workpieces are solved.

Description

technical field [0001] The invention relates to the technical field of centerless grinding heads, in particular to a float-over type centerless grinding head. Background technique [0002] When grinding slender and relatively large shaft workpieces, the actual straightness and radius of the workpiece are two factors that affect the grinding accuracy. The greater the slenderness ratio of the workpiece, the more difficult it is to grind. However, some workpieces, such as piston rods, have a large slenderness ratio, and it is impossible not to bend at all, but some bending will not affect the use requirements. The important thing is the diameter error and roughness error. The first choice to solve such problems The finishing solutions are channel grinding and centerless grinding. The efficiency of channel grinding is low, but the high efficiency centerless grinding with a diameter of more than 160 is very expensive. Contents of the invention [0003] The technical problem t...
