Technical Field
The invention belongs to the field of precision instruments, and particularly relates to a position adjusting device for a grinding wheel dressing pen, a grinding wheel dresser and a position adjusting method for the dressing pen.
Background
In the field of grinding in machining, particularly in the case of contour dressing of a circular grinding wheel by molding grinding, two methods of dressing the circular grinding wheel by a molding method using a molding diamond roller or dressing the circular grinding wheel by a trajectory method (also referred to as a generating method) of a dressing pen tip in which a single-grain diamond (including a synthetic diamond CNB material) is embedded are generally used. Most of track dressing methods generally adopt a horizontal or vertical universal dresser to dress an arc grinding wheel except for a numerical control grinding machine.
In the dressing mode, for arc grinding wheels with different radiuses, the dressing pen point needs to be subjected to left-right centering adjustment and radius adjustment of a rotating axis on the dresser, and the left-right centering adjustment aims to reduce the roundness error of a dressing arc, which is particularly suitable for small arcs; the adjustment of the radius adjustment to the axis of rotation is for the radius of the trim to be accurate. Most trimmers are adjusted to the radius by adopting a special gauge, the distance plug gauge measuring mode from the fixed inner height of the special gauge to a trimming pen point is adopted, once the trimmer is fixed, the trimming pen needs to be moved integrally when the radius is not adjusted, the plug gauge is recombined to be adjusted and fixed, and secondary fine adjustment of the trimming pen cannot be realized.
Furthermore, after the grinding wheel is dressed in the machining process, the dressing pen part has slight loss, and the existing adjusting structure is inconvenient for secondary compensation fine adjustment. Meanwhile, the left and right centering mechanisms of the existing dresser are matched with a sliding rail through a sliding groove to realize adjustment, and the adjusting kinematic pair mechanisms are relatively complex in structure, large in gap, poor in rigidity and troublesome to adjust.
