我厂在BM021A摩托车发动机缸体的珩磨加工中,设计制造了一种单支点浮动式珩磨头。与传统的双支点固定式珩磨头相比,单支点浮动式珩磨头具有结构简单、制造容易和造价低等特点。这种磨头适用于包括具有断续孔在内的各种缸体内孔加工。使用效果较好。一、结构及工作原理单支点浮动式珩磨头如图1所示,主要由磨条2、磨条夹板4、调节锥体6、磨头体7和调节柱9组成。单支点浮动式是 I plant BM021A motorcycle engine honing cylinder body, designed and manufactured a single fulcrum floating honing head. Compared with the traditional two-point fixed honing head, the single-point floating honing head has the advantages of simple structure, easy manufacture and low cost. This grinding head for a variety of cylinder bore including intermittent holes, including processing. Use better. First, the structure and working principle Single fulcrum floating honing head shown in Figure 1, mainly by the mill 2, stripping bar 4, adjust the cone 6, the grinding body 7 and the adjustment column 9 composition. Single pivot floating yes
