Measurement tool and method for docking surface gap of cabin section of manned spacecraft

The invention provides a manned spacecraft cabin butt joint surface gap measuring tool, which comprises a special base, the shape of the special base is adaptive to the size and shape of a reference surface of a measurement target position, and the contact area of the special base and the reference surface can be increased; and the lever indicator is arranged on the special base. The height of the special base meets the following conditions that after the lever indicator is installed on the special base, when a measuring swing rod of the lever indicator is placed on a measuring face, the included angle between the axis of the measuring swing rod and the measuring face is smaller than 15 degrees. By using the tool, the docking surface gap of the cabin section of the manned spacecraft can be measured in a narrow space, and the measurement method is simple and high in precision. 本发明提供一种载人航天器舱段对接面间隙测量工装，包括：专用底座，所述专用底座的形状适应测量目标位置基准面的大小和形状，能够增大所述专用底座与所述基准面接触面积；杠杆百分表，安装在所述专用底座上。所述专用底座的高度满足以下条件：使得所述杠杆百分表安装于所述专用底座后，所述
