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...
