MB1632端面磨床,一般作磨削工件的外圆及端面台肩用。机床的砂轮架上部装有专门的液压仿形机构,可按样板修整出磨削端面及外圆的直角型砂轮,如图1所示。横向油缸带动横拖板1作横向运动,随动滑阀2带动纵向拖板3作纵向运动。修整砂轮时,这套机构实现了仿形触头4与修整器头子5在平行于砂轮轴截面的平面中的两坐标运动;而任何平面上的运动轨迹都可由两个互成角度的运动合成。根据这个原理,我们将MB1632端面磨床改装成可磨削母线为曲线的回转体。具体做法如下:
MB1632 face grinder, generally used for grinding the outer surface of the workpiece and shoulder. The upper part of the wheel frame of the machine is equipped with a special hydraulic profiling mechanism, which can be used to trim the right-angle grinding wheel with the grinding end face and the outer circle according to the model, as shown in FIG. 1. The transverse oil tank drives the transverse carriage 1 to move transversely, and the longitudinal slide plate 2 drives the longitudinal carriage 3 to move longitudinally. When dressing the grinding wheel, the mechanism realizes the two-coordinate movement of the profiling contact 4 and the dresser head 5 in a plane parallel to the section of the grinding wheel axis; and the trajectory of any plane can be synthesized by two mutually angled motions . Based on this principle, we converted the MB1632 face grinder into a revolute body that can grind the busbar to a curve. Specific practices are as follows:
