Embodiment Construction

[0018] See attached figure 2 , the constant force process tie rod in this application adopts figure 1 It is transformed from the tie rod of the landing gear door of the medium aircraft, which maintains the basic characteristics of the original tie rod. The process pull rod is connected by the left joint 1, the left rod body 2, the tension sensor 3, the right rod body 4, and the right joint 5 in a threaded form to form a whole rod-shaped structure with adjustable length. The force measuring display 6 and the tension sensor 6 are connected by cables, and Placed outside the rod 6.

[0019] attached image 3 Among them, the pull rod adjusting seat includes a bottom plate 11, a sliding support 8, a rotating fork ear 9, and a fixed support 13. One end of the bottom plate 11 is provided with a concave chute 7, and the sliding support 8 is embedded in the concave chute 7, and can be moved along the The chute moves, and the rotating fork lug 9 is installed on the sliding bearing 8 ...

Abstract

The invention provides an undercarriage cabin door pull bar force-fixing technological apparatus and an adjusting and installing method. The technological apparatus comprises a technological pull bar and a pull bar adjusting and installing seat. The technological pull bar is prepared by following steps: selecting an undercarriage hatch door pull bar, cutting off the undercarriage hatch door pull bar from the center of the undercarriage hatch door pull bar, and then connecting two sections of the undercarriage hatch door pull bar by a pull force sensor to form the technological pull bar. The length of the technological pull bar is the same as that of the original pull bar, and the characteristics of the original pull bar are maintained. The pull force of the technological pull bar is measured, the length of the technological pull bar is fixed by the pull bar adjusting and installing seat, then the length of the undercarriage hatch door pull bar is adjusted on the adjusting and installing seat, and then the undercarriage hatch door pull bar is installed on a plane.

Description

technical field [0001] The application relates to the technical field of aviation manufacturing and assembly, and is particularly suitable for the installation of large-scale aircraft landing gear door tie rods. Background technique [0002] The landing gear doors of large aircraft are mostly left-right symmetrical structures, and the closed shape of the left and right doors should conform to the overall curved surface shape of the aircraft. The opening and closing of the left and right hatches is accomplished by a pull rod mechanism, which provides the pulling force for closing the hatches. When the pull rod is installed, it is necessary to adjust the length of the pull rod to ensure that a certain closing force is achieved when the hatch is closed. The method of installing the pull rod of the landing gear door is to install one end of the pull rod on the joint of the door, and the other end on the mechanism that drives the pull rod to swing. Adjust the length of the pull ...
