specific Embodiment approach 2

[0043] Specific implementation mode two: combination Figure 6-8 , 10 illustrates this embodiment, the adapter 6 described in this embodiment has four corners, each corner is connected with a cylindrical insert 6-1, and there is a large jack in the cylindrical insert 6-1; A slot 6-1-1 is formed between two cylindrical inserts 6-1 oppositely arranged on the same side; there is a triangular insert 6 at the upper end of the connection between each cylindrical insert 6-1 and the adapter 6 -2; the triangular insert 6-2 has a small jack; the adapter 6, the cylindrical insert 6-1 and the triangular insert 6-2 are integrally formed;

[0044] A hinge 10 is installed between the two cylindrical inserts 6-1 oppositely arranged on the same side.

[0045] Other composition and connection methods are the same as those in Embodiment 1.

specific Embodiment approach 3

[0046] Specific implementation mode three: combination Figure 1-5 , 9, 10, 12, and 13 illustrate this embodiment. The capture finger described in this embodiment includes an inner capture finger 2 and an outer capture finger 3; The two sides of the part 6; the gaps at the two ends of the upper cover plate 1-1 and the two side gaps at the upper end of the support wall 1-4 form two telescopic holes, which are respectively the first telescopic holes 1-1- 1 and the second telescopic hole 1-1-2; the capture end of the inner capture finger 2 extends out of the support wall 1-4 through the first telescopic hole 1-1-1, and the capture end of the outer capture finger 3 passes through the second telescopic hole 1 - 1-2 protrude from the support wall 1-4.

[0047] Other compositions and connection methods are the same as those in Embodiment 1 or 2.

Abstract

A three-finger non-cooperative target capturing mechanism and its capturing method relate to the technical field of space robots. The present invention provides a three-finger non-cooperative target capturing mechanism to solve the disadvantages of large volume and heavy mass of the existing capturing mechanism. The driving device of the present invention is arranged in the supporting wall, the top end of the ball screw shaft is hinged on the upper cover plate and is rotatable, and the bottom end is connected to the driving device; the screw nut is sleeved on the ball screw shaft And it is combined with the ball screw shaft to form a screw pair; the adapter is tightly sleeved on the screw nut and hinged with the bottom end of the capture finger through a hinge; the capture end of the capture finger passes through the expansion and contraction formed by the upper cover plate and the support wall The hole protrudes from the support wall and is located at the upper end of the upper cover plate; the rotation of the ball screw shaft drives the screw nut to move up and down linearly, thereby driving the capture finger to expand and contract relative to the support wall. The invention is used for the capture of non-cooperative targets.

Description

technical field [0001] The invention belongs to the technical field of space robots and relates to a non-cooperative target capturing mechanism, in particular to a three-finger non-cooperative target capturing mechanism and a capturing method thereof. Background technique [0002] With the development of technology, countries all over the world have increased their research efforts in the field of aerospace. However, the earth's orbital resources are scarce, especially the geostationary orbit used as a communication satellite, which is an extremely precious and unique orbit. Therefore, on-orbit capture technology has become a research hotspot and difficulty in the aerospace field worldwide. On-orbit acquisition of non-cooperative targets will play an important role in auxiliary agency deployment, satellite refueling, repair and replacement of faulty components, etc. A major technical difficulty in on-orbit capture of non-cooperative targets lies in the design of the capture...
