Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0021] Please also see figure 1 and figure 2 , The high-precision adjustable limit device of the present invention is composed of two parts: the adjustment cover plate assembly 1 and the adjustment support assembly 4 . The two components are respectively located on both sides of the fixing frame 3, and are fixed on the fixing frame 3 by screws 2. The fixing frame 3 is designed with a waist-shaped hole. When the position of the limit device needs to be adjusted, loosen the screws 2. Move the adjustment cover assembly 1 up and down, and the adjustment support assembly 4 can move up and down within a certain range together with it.

[0022] see image 3 , the middle part of the adjustment block cover 13 of the adjustment cover assembly 1 is provided with a switch adjustment piece 11 and a micro switch 14, wherein the switch adjustment piece 11 and the micro ...

Abstract

The invention belongs to the technical field of mechanical structures, and relates to an adjustable limit device for an aircraft unfolding mechanism. The high-precision adjustable limit device of the present invention includes an adjustment cover assembly (1) and an adjustment support assembly (4), wherein the adjustment cover assembly (1) passes through the screw (2) around the fixing frame (3) The waist-shaped hole is connected with the adjustment support assembly (4) on the other side, so that the adjustment support assembly (4) can be adjusted in position along with the cover plate assembly (1) along the waist-shaped hole of the fixing frame (3). The high-precision adjustable limit device of the present invention can realize the independent adjustment of the limit position and the independent adjustment of the switch position after being installed by adjusting the specific structural design of the cover plate assembly and the adjustment support assembly, thereby effectively improving the position adjustment accuracy of the unfolding mechanism. Moreover, the utility model has the advantages of simple structure, light weight, small volume, convenient installation and adjustment, easy popularization and application, and has great practical application value.

Description

technical field [0001] The invention belongs to the technical field of mechanical structures, and relates to an adjustable limit device for an aircraft unfolding mechanism. Background technique [0002] In the deployment mechanism used by a certain type of aircraft, according to actual needs, the accuracy of the mechanism rotation position is required to be ±0.4mm, so it is necessary to accurately limit the deployment position. The limit device of the traditional aircraft deployment mechanism generally uses a number of fixed limit blocks to limit the position, and relies on the installation accuracy of the limit blocks to ensure the positioning accuracy of the mechanism. However, due to the large errors accumulated during the processing and assembly of other parts such as the mechanism mounting bracket, it is difficult to ensure the positioning accuracy of the mechanism if the traditional limit device is used. Contents of the invention [0003] The purpose of the present ...
