An installation platform for precise attitude adjustment of engine adapter casing

Abstract

The invention relates to an accurate attitude adjustment installation platform for an engine switching casing. The installation platform comprises a driving chassis (1), a lifting mechanism (2) and areplaceable pre-installation platform (3), wherein lifting mechanism (2) is fixedly installed right above the driving chassis (1), the replaceable pre-installation platform (3) is fixed right above the lifting mechanism (2) through bolts, the driving chassis (1) includes an electrically-driven chassis (1-1), a Mecanum wheel (1-2) and a wired remote control operator (1-3), the lifting mechanism (2)includes support rods (2-1), a rotary lifting electrically-driven vertical column (2-2) and an upper platform (2-3), and the replaceable pre-installation platform (3) includes a switching casing support platform (3-1), a platform lifting bracket (3-2) and a casing lifting lug (3-3).

Description

technical field [0001] The invention belongs to the field of aero-engine testing, and relates to an installation platform for precise attitude adjustment of an engine adapter casing. Background technique [0002] Engine bench installation is a complex process that is difficult to streamline from both a management and a technical point of view. In recent years, with the application of digitization, automation and information technology in the aviation industry, my country's aviation manufacturing technology level has been greatly improved. Research and development of parts intelligent production. There is no doubt that the use of optimized process equipment has greatly improved assembly efficiency and assembly safety. [0003] At present, during the ground test of the whole engine, since the auxiliary test pieces of the engine such as the starter, the starter adapter casing, and the accessory casing are generally located under the engine, and the driving of the test bench is...

AI Technical Summary

Problems solved by technology

[0004] This installation method has the following defects: ①It is laborious and time-consuming to load and unload: In a compact space, in terms of interface docking such as lateral / vertical movement and in-situ deflection, there are often a large number of workers who repeatedly move and correct the position and direction of the test piece, and the installation efficiency is low. , unable to meet the growing demand for upper and lower stage installation

② Poor compatibility of tooling: due to the frequent adjustment of the installation position of the test piece, a variety of tooling needs to be processed to adapt to the test piece, which increases the test preparation work and reduces the installation efficiency of the upper and lower platforms
