The invention relates to a sealing and riveting tool and a sealing and riveting method applicable to a composite vertical
tail wing box of an
airplane. According to a technical scheme in the invention, the sealing and riveting tool is such structured that a
handle is connected with an extension tube; the extension tube is connected with a magnetic chuck; one end of a wind
pipe is connected with awind-controlled switch, and the other end of the wind
pipe passes through the
handle and the extension tube and then communicates with the magnetic chuck; and an
endoscope lens is mounted on the magnetic chuck and is connected with a display screen through a wire. As the sealing and riveting tool is employed for sealing and riveting of the composite vertical
tail wing box of the
airplane, a
fastener can be inserted into a pre-drilled
fastener hole in the enclosed wing box under the guidance of the
endoscope lens, and then the wind-controlled switch on the wind
pipe is turned on so as to fix stringers and / or angular pieces in an enclosed box section via the
fastener. According to the invention, the assembling sequence of the wing box is rationally formulated, an
endoscope is cooperatively used for observation and is manually hand-held, and the installation of fasteners between stringers and angular pieces is realized through an inherent lightening hole in the wing box, so
engineering requirements are met.
