Abstract

The invention discloses a drilling and interference bolt-inserting integrated device and method. The drilling and interference bolt-inserting integrated device comprises a station conversion module, aspindle module and a bolt-inserting module. The station conversion module comprises a driving mechanism, a double-station connecting plate and a connecting belt mechanism connected between the driving mechanism and the double-station connecting plate; the spindle module is arranged at a first station of the double-station connecting plate and used for drilling and dimpling of wall plate connecting holes; the bolt-inserting module is arranged at a second station of the double-station connecting plate and used for interference bolt-inserting of high-locking bolts; and the driving mechanism of the station conversion module drives the connecting belt mechanism to rotate, so that station conversion of the first station and the second station is achieved. Thus, by adopting the drilling and interference bolt-inserting integrated device, after the to-be-drilled holes are drilled, the station conversion module is rotated by a fixed angle, then the station states of the spindle module and the bolt-inserting module can be switched, thus interference bolt-inserting of the high-locking bolts is completed, and the anti-fatigue property and assembly efficiency are improved.

Description

technical field [0001] The invention relates to the field of digital assembly of intelligent manufacturing, in particular to an integrated device and method for making holes and interfering with inserting nails applied to large aircraft wall panels. Background technique [0002] There are 1.5 to 2 million rivet / bolt connections on an aircraft, and mechanical connections require holes to be prepared on the parts. For the part itself, it not only weakens the strength of the part, but also forms stress concentration around the hole, and the residual stress left during the hole making will have a great impact on the ability of the part to resist alternating fatigue loads. In order to reduce this effect, the interference strengthening of the connection hole has become an important technological measure to improve the fatigue life of the connection structure. At present, the riveting actuator provided by the existing technology can only realize the functions of hole making, nail ...
