+# KFL001 反装固定板 V1
+
+两块板几何相同，按此模型加工 2 件。板材暂按 8 mm 厚铝板，具体铝合金牌号可按加工店可用材料确定。所有孔及槽均贯穿，不加工螺纹。
+
+- 板外形：76 × 80 × 8 mm。
+- 中心避让孔：直径 39 mm，按用户确认的轴承凸起直径 38 mm 留出单边 0.5 mm 名义径向间隙；孔心位于板宽中央、距板底边 51 mm。
+- 轴承固定孔：2 个直径 7 mm 通孔，中心距 48 mm，和中心孔同高，适配 M6 螺栓。
+- 角码固定槽：2 个水平长槽，长 9.5 × 宽 5.5 mm，槽心距 47 mm，距板底 9 mm，适配 M5 螺栓。按螺杆公称直径 5 mm 算，两槽理论左右移动范围合计 4.5 mm；实际范围受角码、紧固件和误差影响。
+- 每块固定板使用两只此前选定的 50 × 31 × 19 × 3 mm 长孔角码与 3030 横梁连接。两板高度和左右位置先松装调整，穿入 12 mm 轴检查转动是否顺畅，然后紧固；轴承和电机须同轴调整，不能靠拧紧螺栓强行拉正。
+
+轴承固定孔与中心孔边之间的名义净距为 1 mm。以直径 12 mm 的平垫圈为例，其内侧会伸入中心孔约 1.5 mm；实装时需核查垫圈及螺母的有效压紧接触和轴承座外形，不能以几何检查代替动态强度验证。用户已说明不使用轴承顶丝，故没有设计顶丝操作孔。
+
+FCStd 是带 Parameters 表格的可编辑模型，STEP 是单零件加工交换模型；PDF/PNG 是尺寸图。现有装配示意的两块板与本模型在几何上相同，轴承、螺栓、角码和整机尚未实物试装，试制后应检查紧固、间隙和运转情况。
