Problems solved by technology

The vertical foot control mechanism is fully assembled and then installed on the aircraft. However, when it is connected to the aircraft, assembly errors will accumulate, resulting in failure to meet the system functions and requiring repeated disassembly and adjustment.
However, due to the narrow construction space and complex mechanism, it is quite inconvenient to use and maintain. In the past assembly and adjustment process, disassembly and adjustment were extremely inconvenient, and a lot of manpower and material resources were wasted. In order to save assembly cycle and assembly time, and reduce waste of resources etc., specially developed this assembly adjustment method

Embodiment Construction

[0027] This part is the embodiment of the present invention, which is used to explain and illustrate the technical solution of the present invention.

[0028] A method for assembling an aircraft foot control mechanism, comprising the following steps:

[0029] Step 1, adjust the axial distance between the foot control fixed bracket 3 and the aircraft structure to be the theoretical distance L, then manufacture the connecting hole 3a between the foot control fixed bracket 3 and the aircraft structure, install the foot control fixed bracket 3 on the aircraft structure; adjust the brake The length of the pull rod 5 reaches the specified size;

[0030] Step 2: Assemble pedal 1, pedal column 2, connect rocker arm 4 and brake lever 5, and fine-tune the length of brake lever 5 so that the connecting rocker arm 4 is perpendicular to pedal column 2;

[0031] Step 3: Complete the assembly of the rocker arm 7 and the connection between the rocker arm 7 and the aircraft structure to ensur...

Abstract

The invention belongs to the technical field of aviation, and discloses an aircraft foot control mechanism assembling method. A process separation surface is designed through a rotating rocker arm anda pedal stand column, the problem of assembling error accumulation between the rotating rocker arm and the pedal stand column is compensated by adjusting the length of an adjustable connector on a rotating pull rod, the adjusting period is greatly shortened, the adjusting time is greatly shortened, and the adjusting efficiency is improved; the wedge-shaped cushion block is added to the rotating rocker arm, so that the adjusting efficiency is greatly improved; through installation and adjustment of the pedal stand column and the foot control fixing support, the axial distance of the structureis guaranteed, the problem that secondary or multiple adjustment of the system is caused by rotation of assemblies such as the pedal stand column around a point is solved, and the adjustment efficiency is greatly improved. In comparison before and after the method is applied, the general adjustment and assembly period can be shortened, and the installation and adjustment efficiency of the foot control mechanism is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of aviation assembly, and relates to an installation method of an aircraft control mechanism, in particular to an assembly method of an aircraft foot control mechanism. Background technique [0002] Shaanxi Aircraft Industry (Group) Co., Ltd. discloses a new type of vertical foot control mechanism in ZL200920350493.6 "A Vertical Foot Control Adjustment Mechanism for Aircraft". The foot control mechanism is used in various types of medium-sized medium-range transport aircraft and special aircraft in China, and has achieved certain economic benefits and application value. The vertical foot control mechanism is fully assembled and then installed on the aircraft. However, when it is connected to the aircraft, assembly errors will accumulate, resulting in failure to meet the system functions and requiring repeated disassembly and adjustment. However, due to the narrow construction space and complex mechanism, it...
