Abstract

The invention provides an annular numerical control automatic hole manufacturing system used for butt joint assembly of an airplane body. The annular numerical control automatic hole manufacturing system comprises two annular rail assemblies, at least two four-drive carrying devices moving along the two annular rail assemblies, and automatic hole manufacturing devices installed on the four-drive carrying devices. Each annular guide rail assembly comprises a flexible rail module and a vacuum sucker assembly. Each four-drive carrying device comprises a first double-drive electric control trolley and a second double-drive electric control trolley. Each automatic hole manufacturing device comprises a normal posture adjusting mechanism, a drilling and milling hole manufacturing unit and a pressing and chip removing mechanism. By means of the annular numerical control automatic hole manufacturing system, due to the fact that a certain number of the automatic hole manufacturing devices and a certain number of the four-drive carrying devices are reasonably arranged, the overall rigidity of the annular rail assemblies can be enhanced, and therefore the machining quality of holes is ensured, and the hole machining efficiency can also be obviously improved.

Description

technical field [0001] The invention relates to a numerically controlled automatic hole-making system, in particular to a ring-shaped automatic hole-making system for fuselage docking assembly, belonging to the field of automatic hole-making for aircraft digital assembly. Background technique [0002] The quality and efficiency of the fuselage docking assembly holes directly restrict the assembly cycle, manufacturing cost and safety performance of the whole machine, and have always been a research hotspot in aircraft digital assembly. In this regard, foreign countries took the lead in proposing a flexible track hole-making system. Therefore, the equipment has a high degree of automation, flexibility and convenience, and can complete the functions of drilling and countersinking at one time, but the overall rigidity of the system is poor, and the processing stability is insufficient. In order to solve the above problems, Chinese invention 201410123510.8 proposes a system and ...
