| 目的 目前对内孔的珩磨加工，一种珩磨头只能加工一种口径的内孔，加工尺寸单一，适应性差。为了提高珩磨头的通用性，适应小批量、多规格珩磨加工，介绍一种尺寸可调的珩磨头。 方法 对珩磨头尺寸调节原理进行了介绍，并分析了珩磨时工件所受的珩磨力以及珩磨头的运动情况。用SolidWorks 建立了装置的三维模型，并加工出了适应孔径为 95~125 mm 的珩磨头实物样机。通过对内径为φ98 mm 和φ106 mm 的不锈钢钢管进行加工实验，加工 6 min 后，获取了表面粗糙度 Ra 变化曲线和加工后的表面形貌。 结果 加工后φ98 mm 管的表面粗糙度 Ra 值由 2.174 μm 降低到 0.869 μm，φ106 mm 管的表面粗糙度由 1.582 μm 降低到 0.758 μm。加工后的工件表面变得光滑、明亮，表面形貌得到明显改善。 结论 珩磨头结构简单易于实现，在普通机床上即可使用，通过实验验证了装置的可行性。 |

| Objective At present, a honing head can only hone holes with a single size, which is poor in suitability. In order to improve the versatility of honing head and to adapt low-volume and multi-standard honing, an adjustable honing head was introduced. Methods Adjustment principle of this honing head was introduced. The honing force suffered by workpiece and the movement of this honing head were analyzed. The 3D modeling was built using the software SolidWorks, and the physical prototype which adapted to the inner diameter from 95 mm to 125 mm was manufactured. Experiments were carried out using stainless steel pipe with inner diameter of 98 mm and 106 mm respectively. After 6 minutes of honing, the Ra curve and surface topography were acquired. Results Ra decreased from 2.174 μm to 0.869 μm for the stainless steel pipe with inner diameter of 98 mm, and Ra decreased from 1.582 μm to 0.758 μm for the one with inner diameter of 106 mm. The surface became smooth and bright, and the surface topography was significantly improved. Conclusion The honing head described in this article was simple and easy to use, and it could be used on general machine tool. The feasibility of this device was verified by experiments. |
