The utility model discloses an annular surface flatness detection device, and relates to flatness detection of an annular surface with a diameter of more than 1 meter and detection precision of +/-5 [mu] m. The device comprises a main frame, fulcrums and rib plates, the main frame is of an annular structure. The number of the supporting points is not less than four, the multiple supporting pointsare evenly fixed to one surface of the main frame at intervals, and the tail ends of the supporting points are located on the same plane. The rib plate is fixed to the other surface of the main frameand used for guaranteeing the rigidity of the main frame. The special detection device is manufactured according to the size of the annular surface, the detection speed is high, and the use is convenient; the annular surface flatness multi-point detection device detects the flatness of the annular surface in a multi-point manner and has comprehensive detection results. 本实用新型公开了一种环形表面平面度检测装置，涉及的是对直径＞1米，检测精度±5μm的环形表面的平面度检测。包
