Be applied to frock that high accuracy air supporting main shaft axle sleeve ground processing

The utility model discloses a be applied to frock that high accuracy air supporting main shaft axle sleeve ground processing, including adjusting nut, adjust the end cover, grind the overcoat, the dabber. Wherein grind outer suit at the spindle to grinding the internal diameter and the outside diameter of mandrel of overcoat and respectively installing one and adjust the end cover according to the same taper fit, grinding overcoat both ends, adjust end covers for two and compressed tightly by adjusting nut, it has great chamfer to grind the processing of overcoat both ends. The utility model discloses can improve the machining precision and the efficiency of axle sleeve, reduce because of processing the cost that different diameter grinding stick increases. 本实用新型公开了种应用于高精度气浮主轴轴套研磨加工的工装，包括调节螺母，调节端盖，研磨外套，芯轴。其中研磨外套装在芯轴上，并且研磨外套的内径和芯轴的外径按相同的锥度配合，研磨外套两端各安装个调节端盖，两个调节端盖被调节螺母压紧，研磨外套两端加工有较大的倒角。本实用新型可以提高轴套的加工精度和效率，减少因加工不同直径研磨棒而增加的成本。
