+# KFL001 拱形反装固定板 V2
+
+按此模型加工相同板 2 件，材料为 8 mm 厚铝板；各孔槽均贯穿，不加工螺纹。参考此前转换盘的做法，只在板外轮廓前后两面做 1.5 × 45° 倒角，孔口不倒角。
+
+- 最大外形：76 × 75 × 8 mm。上边为 R60 mm 圆弧，圆心在板宽中线、距底边 15 mm；圆弧最高点距底 75 mm，两端与左右直边交点距底约 61.43 mm。
+- 中心孔直径 39 mm，轴心距底 51 mm，按用户提供的 Ø38 mm 轴承凸起留名义单边 0.5 mm 间隙。两侧轴承固定孔 Ø7 mm，间距 48 mm，供 M6 螺栓使用。
+- 两个横向长槽 9.5 × 5.5 mm，槽心间距 47 mm，槽心距底 9 mm，用 M5 螺栓连接此前选定的 50 × 31 × 19 × 3 mm 长孔角码。两板松装时调整后穿轴检查，轴承与电机同轴应按实物调整，避免强行拉正。
+- 名义最小距离：Ø39 中心孔至顶端外缘 4.5 mm；扣除 1.5 mm 倒角后，板面平坦部分最窄约 3 mm。底部槽至底部外缘 6.25 mm，扣除倒角后板面平坦部分约 4.75 mm。
+- 中心孔到两侧 Ø7 孔的边缘仍只有 1 mm 名义间距。Ø12 垫圈向中心孔悬出约 1.5 mm，须实物检查垫圈与螺母的有效压紧接触。用户已说明不使用轴承顶丝。
+
+与 V1 对比，V2 只削减材料，孔、槽和安装基准不变；旧装配的板与角码几何不相交，因此该材料削减不会新增相交。用 Klee 和 Motedis 的参考 KFL001 模型比较，两个参考件在 V1、V2 的名义法兰接触面积相同，且没有实体穿透；这些模型不能代替实物轴承、紧固件的试装和动态强度验证。
+
+FCStd 通过 Parameters 表格可编辑各尺寸；STEP 是单件 CNC 模型。尺寸图及图中文字仅说明名义尺寸；实物应检查凸起、角码、垫圈、螺栓和间隙。
