The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present invention.

The features and capabilities of the present invention are described in further detail below in connection with the examples.

Embodiments of the aircraft segment docking device of the present invention:

as shown in fig. 1-4, the main components of the docking device for the aircraft section are a fixed section supporting mechanism 101, a docking section supporting mechanism 102 and a pose laser detection mechanism 103. The fixed section supporting mechanism 101 and the docking section supporting mechanism 102 are both fixedly arranged on a docking base 104, wherein the fixed section supporting mechanism 101 can adjust the position relative to the docking base 104 in the direction perpendicular to the sections to be docked, and the adjustment of the position is realized by moving a fastener along a T-shaped groove 41 arranged on the docking base 104.

Fig. 13-16 show the structure of the fixed section support mechanism. The function of the fixed section support means 101 is to fix the aircraft section to be docked, the fixed section support means 101 thus being named because the section to which the fixed section support means 101 is adapted cannot rotate relative to the means. In this embodiment, as shown in fig. 13 to 16, the main constituent parts of the fixed section support mechanism 101 are a fixed support seat 11 and a movable support device 12, wherein the fixed support seat 11 includes legs and a table top, and is integrally of a frame type structure. The mobile support device 12 comprises a mobile platform 121, a bearing plate 122 arranged on the mobile platform 121 and a section fixing device arranged on the bearing plate 122. The movable platform 121 is in guiding fit with the table top of the fixed supporting seat 11 through the sliding block 123 and the sliding rail 124, and the guiding direction is the butt joint direction of the sections to be butt-jointed.

The carrying plate 122 is supported on the moving platform 121 through elastic components, in this embodiment, four elastic components are provided and supported at four points of the carrying plate 122, and the posture of the carrying plate 122 can be adaptively changed through elastic deformation, so that the posture of the supported section can be automatically adjusted. The spring member is here embodied as a disc spring 125. Of course, it should be understood by those skilled in the art that, in order to achieve the desired effect of the present invention, in other embodiments, the number of elastic members may be three, the three elastic members may be arranged in a triangle, or more elastic members may be used, and the elastic members may specifically be coil springs, leaf springs, etc.

At the side remote from the docking section support mechanism 102, a movable stroke of the movable platform 121 is provided, in which the movable platform 121 can reciprocate, and at the same time, an elastic device 126 is provided for the movable platform 121, and the elastic device 126 functions to store energy by deformation when the movable platform 121 moves in a direction remote from the docking section support mechanism 102, and then drive the movable platform 121 to move in a direction close to the docking section support mechanism 102 by energy release, thereby realizing compensation of axial relative displacement between the two sections in the docking process. In the present embodiment, the elastic device 126 is specifically a compression spring, which is mounted between the spring seat 127 and the movable platform 121. However, it should be understood by those skilled in the art that in other embodiments, the elastic device 126 may be provided as a tension spring for the same purpose, in which case the spring seat is only required to be moved to the opposite side of the current position, or to the left and right sides of the current position and extend in the left and right directions.

The function of the segment securing means is to secure the segments to be docked relative to the carrier plate 122. In this embodiment, the section fixing device specifically adopts a fixing embracing ring assembly, where the fixing embracing ring assembly is formed by two fixing embracing rings 128 arranged at intervals coaxially, and each fixing embracing ring 128 is fixed on a vertical wall formed by bending upwards at the edge of the bearing table. When the clamping device is used, the sections can be clamped and fixed by two clamping rings at different positions. Although the fixing band assembly is used as the segment fixing device in the present embodiment, in other embodiments, the segment fixing device may also use a fixing band, a compression bar, a fixing clip, or the like, which can also meet the requirement of fixing the segment.

In order to limit the movable travel of the movable platform 121, a proximity switch 105 is provided on the fixed support 11, the proximity switch 105 is provided at one side of the guide rail, and when the movable platform 121 moves to this position, the proximity switch 105 is touched, and then the switch of the driving mechanism (mechanism for pushing the movable support backward) is controlled.
