An integrated device and method for making holes and interfering with inserting nails

Abstract

The invention discloses an integrated device and method for hole-making interference and nail insertion. The device includes: a station conversion module, a spindle module and a nail insertion module; wherein the station conversion module includes a driving mechanism, a double-station connecting plate and a connecting A joint mechanism between the driving structure and the double-station connecting plate; the main shaft module is arranged at the first station of the double-station connecting plate, and is used for drilling and spot-sinking of the wall plate connecting holes; The nail insertion module is arranged at the second station of the double-station connecting plate, and is used for interfering nail insertion of high-lock bolts; the driving mechanism of the station conversion module drives the joint mechanism to rotate to realize the first A station conversion between the station and the second station. It can be seen that with the device provided by the present invention, after the hole making is completed, the station conversion module can be rotated at a fixed angle to switch the station status of the spindle module and the nail insertion module, and complete the interference insertion of the high-lock bolts, improving the resistance Fatigue performance and assembly efficiency.

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 ...

AI Technical Summary

Problems solved by technology

At present, the riveting actuator provided by the existing technology can only realize the functions of hole making, nail feeding, riveting, etc., and can complete the riveting work after hole making, which greatly improves the function of the robot automatic assembly end effector.

However, before the riveting work after hole making, the hole making position needs to be obtained again, and only rivet connection can be performed, and interference high lock bolt connection cannot be realized
