Abstract

The invention provides a gantry type numerical control hole manufacturing system used for airplane wing body abutting joint. The gantry type numerical control hole manufacturing system comprises a gantry bracket assembly, three four-rod pose adjusting mechanisms and three terminal hole manufacturing units. The gantry bracket assembly comprises a door shaped bracket, two perpendicular lifting devices and a horizontal sliding device. Each four-rod pose adjusting mechanism comprises a movable platform, a fixed platform, a first electric telescopic rod, a second electric telescopic rod, a third electric telescopic rod and a fourth electric telescopic rod. Each terminal hole manufacturing unit comprises a T-shaped feed supporting shell body, a T-shaped revolution supporting shell body, a U-shaped revolution shell body, a U-shaped rotation supporting shell body and a rotation driving device. The gantry type numerical control hole manufacturing system is capable of remarkably improving the efficiency and the quality of hole manufacturing of wing body abutting joint and assembly and especially suitable for hole manufacturing of large-size airplane wing body abutting joint and assembly.

Description

technical field [0001] The invention relates to a gantry-type numerical control hole system, in particular to a gantry-type numerical control hole system for aircraft wing-body docking, and belongs to the field of automatic hole-making for digital assembly of aircraft. Background technique [0002] Wing-body joint hole making is one of the key links in the aircraft assembly process. It not only affects the safety performance of the wing-body connection, but also directly restricts the aircraft assembly cycle and manufacturing cost. Due to the influence of factors such as difficult positioning and clamping of the hole-making part, narrow working environment, and large diameter of the connecting hole, manual drilling is mostly used for wing-body butt joint hole making at present. Chinese invention patent ZL201010138456.6 proposes an automatic hole-making system and method for wing-body docking, which provides an automatic processing scheme for the connection holes of wing-body...
