Embodiment 1

[0032] refer to Figure 6 , six connecting rods 1 are connected with six brackets 2 to form a six-bar parallel rod frame. The three lower brackets 16 at equal intervals are connected with the telescope, and the three upper brackets 15 at equal intervals are connected with the satellite platform, and are positioned by the positioning round table 26 on the brackets, adjusted with cutting pieces 3, and fixed with bolts and pins . The diameter of the installation circle where the three upper brackets 15 connected to the satellite platform are larger than the diameter of the installation circle where the three lower brackets 16 are connected to the telescope.

Embodiment 2

[0034] refer to Figure 7 , the diameter of the installation circle where the three upper brackets 15 connected to the satellite platform are equal to the diameter of the installation circle where the three lower brackets 16 are connected to the telescope. A thermal insulation pad 6 is added between the trimming sheet 3 and the satellite deck to reduce the heat transfer between the satellite and the telescope. After adopting such a mounting pole frame, the influence of the thermoelastic deformation of the satellite platform on the telescope can be significantly reduced, the mounting accuracy can be improved, and the weight can be reduced.

Abstract

The invention relates to a flexible joint and a flexible connecting device. The flexible joint comprises a flexible transition sheet, a connection lug sheet and a flexible plate, wherein the connection lug sheet and the flexible plate are respectively and vertically arranged on two side surfaces of the flexible transition sheet, the connection lug sheet and the flexible plate are mutually vertical, two sides of the corner joint of the connection lug sheet and the flexible transition sheet are respectively provided with an upper groove, and two sides of the corner joint of the flexible plate and the flexible transition sheet are respectively provided with an inner groove. The invention solves the technical problem that the existing flange or support is always affected by satellite thermoelastic distortion when installing a telescope. The invention has the advantages of high positioning precision and the like and lowers thermoelastic distortion influence.

Description

technical field [0001] The invention relates to a flexible joint and a flexible connecting device with the flexible joint. Background technique [0002] Existing space telescopes are fixed on satellites through flanges or brackets, and the telescopes and satellites are rigidly fixed as a whole. When the satellite is in orbit, the telescope installed in this way is susceptible to the thermoelastic deformation of the satellite. Contents of the invention [0003] The object of the present invention is to provide a precision mounting pole frame for a space telescope, which solves the technical problem that the existing flange or bracket mounting telescope is easily affected by the thermoelastic deformation of satellites. [0004] Technical solution of the present invention is: [0005] A flexible joint, which is special in that it includes a flexible transition piece and connecting lugs and flexible plates vertically arranged on both sides of the flexible transition piece, t...
