Embodiment Construction

[0073] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0074] Such as figure 1 , 2 The shown satellite adapter of a discrete-point bearing frameless structure includes a column 1 and a hoarding 2 .

[0075] Such as image 3 , 4 As shown, the column 1 is a supporting structure with a cross section, including a cross-shaped vertical plate 3, an upper end surface 4, a lower end surface 5, a C surface 6, a partition 7, a docking coordination hole 8, and a separation spring top. Rod guide hole 9, separation spring installation center hole 10, separation spring installation hole, dividing plate two 11 and the fixed plate 12 along the coaming.

[0076] The cross-shaped vertical plate 3 is spliced ​​by a straight plate and a slanted plate. The straight plate and the slanted plate are perpendicular to each other, and the column 1 is divided into four areas, which are respectively the separatio...

Abstract

The invention relates to the technical field of aerospace assembly, in particular to a discrete point type bearing non-frame structural body satellite adapter and an assembly method of the discrete point type bearing non-frame structural body satellite adapter. The satellite adapter comprises four uprights and four enclosure boards, the uprights and the enclosure boards are arranged at intervals,and assembly holes are formed in the uprights and the enclosure boards. The assembly method includes the following steps of (1) preparation work, (2) locating riveting assembly, (3) drilling, (4) screw joint assembly, (5) butt joint coordination hole forming, (6) quadrant line engraving and steel seal printing, (7) detachment, (8) taper sleeve assembly, (9) installation, reset and alignment trial,and (10) finishing work. According to different size requirements, the size of each region of the uprights can be adjusted, the structure in the mode is more compact and efficient, a good strength and rigidity environment is provided for use of each component, and meanwhile the satellite adapter is simple in structure and convenient to arrange, install and operate.

Description

technical field [0001] The invention belongs to the technical field of aerospace assembly, and in particular relates to a satellite adapter of a discrete-point bearing frameless structure and an assembly method thereof. Background technique [0002] Discrete-point load-bearing frameless structure satellite adapter is an important part of connecting satellite and rocket body structure in the aerospace field. The traditional skin stringer type satellite adapter has a complicated structure. For a specific small and medium-sized satellite, its very The centrosymmetric interface is not easy to meet, and the satellite adapter of composite material also has similar problems, and the product is also more expensive. [0003] Therefore, it is necessary to redesign a satellite adapter. Its product structure is simple, and at the same time, it can meet the requirements of providing the connection interface between the satellite and the rocket body, transfer the load of the star body and...
