Abstract

The invention discloses a multi-shaft posture adjusting platform for airplane engine mounting and belongs to the technical field of assembly automation. The multi-shaft posture adjusting platform is characterized by comprising a worktable (1), a translating mechanism (2), a turntable mechanism (3), a lifting and elevating mechanism (4), a platform base (5) and the like. The lifting and elevating mechanism (4) comprises a left upper slide seat (6), a right upper fixing sea (9), a left lifting mechanism (7) and a right lifting mechanism (8), wherein the left lifting mechanism (7) and the right lifting mechanism (8) are of structures conforming to identical operating principles and has a single-side lifting posture adjusting function. All motion mechanisms are of purely mechanical structures driven by a servo motor. The multi-shaft posture adjusting platform has the advantages that carrying capacity is high, mounting accuracy is high, and adjustment range is large; labor intensity of operators is alleviated, and operation efficiency and mounting quality are improved. The multi-shaft posture adjusting platform is widely applicable to accurate assembly of multi-shaft posture adjustment of heavy parts.

Description

technical field [0001] The invention belongs to the technical field of assembly automation and relates to the design of a multi-axis attitude adjustment platform for aircraft engine installation. Background technique [0002] As the core power component of the aircraft, the aircraft engine needs to be loaded and unloaded frequently and inspected and maintained. However, aircraft engines have the characteristics of complex structure, large volume, high quality, and small assembly gaps, which are difficult to load and unload, which makes it often impossible to achieve accurate attitude adjustment when loading and unloading aircraft engines, and its loading and unloading quality will have an important impact on the dynamic performance of the aircraft. . [0003] At present, when assembling aircraft engines, manual mechanical devices or hydraulic mechanisms are often used to adjust the various attitudes of the engines. This type of equipment mainly has the following deficienci...
