Production line system suitable for machine body assembly

Abstract

The invention relates to a production line system suitable for machine body assembly, which comprises a pit with a track, and a measurement preassembling station, an automatic hole forming station and a manual assembly station are sequentially arranged above the pit in the length direction of the pit. The measuring preassembling station comprises a first numerical control moving platform arranged on the pit in a sliding mode, a shape maintaining frame arranged on the first numerical control moving platform and used for adjusting the posture of the machine body, and a positioner assembly with a six-freedom-degree movement function. The automatic hole making station comprises a second positioner assembly used for being connected with the shape maintaining frame and hole making equipment used for completing hole making of the machine body; the manual assembly station comprises a second numerical control moving platform arranged on the pit in a sliding mode, a third positioner assembly arranged on the second numerical control moving platform and used for being movably connected with the shape maintaining frame, and manual operation platforms arranged on the two sides of the pit in the moving direction of the second numerical control moving platform. And the machine body assembling stress is reduced, assembling of different types of machine bodies is adapted, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of aircraft digital assembly, in particular to a production line system suitable for fuselage assembly. Background technique [0002] The structure of aircraft products is complex, the number of parts is large, and the coordination relationship is complicated. Airframe assembly occupies a large amount of workload in aircraft manufacturing, which greatly affects the quality, manufacturing cost and cycle of aircraft assembly. With the introduction of a large number of advanced CNC machine tools in my country's aviation factories in recent years, the CNC machining capabilities of aircraft parts have been greatly enhanced, the manufacturing cycle of aircraft parts has been greatly shortened, and the processing quality has also been greatly improved. However, the assembly of aircraft components and fuselage still uses the original traditional fixed frame method, which has a long preparation period, low flexibilit...

AI Technical Summary

Problems solved by technology

This set of system products needs to be pre-installed and positioned by means of hoisting and manual mechanical connection with the shape retaining frame. It takes a long time to prepare for assembly, and it is easy to generate assembly stress. At the same time, the layout of the processing equipment is only suitable for the processing of the main starting and intersection holes, end faces and measuring holes, and the scope of application is small.
