Numerical-control electric frame truck for airplane engine mounting

Abstract

The invention relates to a numerical-control electric frame truck for airplane engine mounting and belongs to the technical field of assembly automation. The numerical-control electric frame truck is characterized by comprising a multi-shaft posture adjusting platform (1), a posture adjusting platform frame (2), a long-shaft feed mechanism (3), a truck body frame (4), left and right rotation mechanisms (5), an auxiliary support mechanism (6), hydraulic support legs (7), a driving wheel system (8), a truck body underframe (9), steering wheel systems (10), a driving cab (11), a hydraulic control system and a servo control system. Posture of five shafts is driven and adjusted by a servo motor, and posture of the rest one shaft is manually adjusted. Travelling of the frame truck is driven by the mode of electric vehicle. The numerical-control electric frame truck has the advantages that positioning accuracy is high, maneuverability is good, stability is high, engine mounting efficiency is improved, and labor intensity of operators is reduced. Besides, the numerical-control electric frame truck is applicable to automatic mounting operation of heavy complicated shaft parts requiring multi-shaft posture adjustment.

Description

technical field [0001] The invention belongs to the technical field of assembly automation and relates to the design of a numerically controlled electric carriage used for aircraft engine installation. Background technique [0002] The aircraft engine is the core power component of the aircraft, and it needs to be installed, inspected and maintained frequently. However, the engine has the characteristics of high quality, large volume, complex structure, etc. At the same time, there are also difficult assembly problems such as small assembly clearance, complex inner cabin structure, and easy deformation of installation equipment, which makes it often impossible to achieve accurate attitude adjustment and positioning when the engine is installed. . Therefore, during the installation process, it is necessary to repeatedly adjust the attitude of the engine and perform repeated trial installations. This repetitive installation process occupies most of the labor in engine assembl...

AI Technical Summary

Problems solved by technology

This type of installation equipment often has the following disadvantages: (1) poor rigidity of the mechanism, large load deformation; (2) low design accuracy, it is difficult to achieve precise adjustment of small strokes; (3) less adjustable posture, unable to achieve multi-axis NC adjustment of attitude; (4) low degree of automation, requiring manual operation one by one to adjust the attitude of each degree of freedom; (5) poor maneuverability, most of which require additional transportation tools to transport related installation equipment to the installation site; (6) installation Low efficiency, high labor intensity, requiring multiple assemblers to cooperate and cooperate repeatedly
