由于船舶建造的需要,我厂最近自制了一台80吨肋骨冷弯机。该机液压系统有一只高压油缸,油缸内径φ200_0~(+0.09),长458mm,要求油缸孔的表面粗糙度R_α≤0.63μm。一般内圆磨床无法加工,我厂又无珩磨机。为此,我们设计制造了一种简单的珩磨抛光工具,如图示。该工具可以安装在普通车床的刀架上使用。结构如图示,油石1安放在磨头本体3的四个槽内,为防止油石在工作时滑出槽,在槽子两端用两块挡片4固定。在每根油石的背面装有弹性、尺寸完全相同的两根弹簧2。这样在磨削时,由于弹簧的作用,油
Due to the needs of the shipbuilding, our factory recently made a 80 tons of cold-bending machines. The machine hydraulic system has a high pressure cylinder, cylinder diameter φ200_0 ~ (+0.09), length 458mm, the cylinder bore surface roughness R_α ≤ 0.63μm. General internal grinder can not be processed, I plant no honing machine. To this end, we designed and manufactured a simple honing and polishing tool, as shown. The tool can be installed on the general lathe turret use. The structure is shown in the figure, the whetstone 1 is placed in the four troughs of the grinding head body 3. To prevent the whetstone from sliding out of the trough during work, two blocks 4 are fixed at both ends of the trough. In the back of each stone with a spring, the same size two spring 2. This grinding, due to the role of spring, oil
