Problems solved by technology

At present, large-scale space structures are mainly unfolded structures. However, the carrying capacity of spacecraft is limited, the scale of expansion is limited, and the secondary expansion capability is low. Therefore, on-orbit assembly has become the main method of building large-scale space structures at home and abroad.
[0003] Through the analysis of domestic and foreign literature and data, the current development of space on-orbit assembly is mainly through the experimental verification of astronauts, mainly because the current space operation robot's operating accuracy and intelligence level are limited, and in the space floating state, the dynamic state also more complex

Embodiment 1

[0059] Such as figure 1 As shown, this example provides a radial insertion self-locking quick joint suitable for the assembly of space truss structures, mainly including node joints 2 and rod joints 3 . Wherein, the node joint 2 is connected with the truss node 1 to form a node joint assembly 5 , and the bar joint 3 is connected with the truss bar 4 to form a bar joint assembly 6 . The node connecting piece 201 in the node joint 2 and the bar connecting piece 301 in the bar joint have the same shape structure, and have a matching concave-convex structure in the same lateral direction to achieve axial connection. When the node joint assembly 5 and the bar joint After the components 6 come into close contact in a specific radial direction, when the axes, bumps, and surfaces of the node connector 201 and the rod connector 301 are completely coincident, the locking ring 303 of the rod joint 3 pops up to surround and lock the node connector 201 and the rod connection Part 301 real...

Embodiment 2

[0066] This embodiment provides a case of using the connector of the present invention to realize quick connection of the connector.

[0067] Such as Figure 4 As shown, this example reveals the state of the connector before it is assembled and connected. The truss node 1 is pre-connected with the node joint 2 as a node joint assembly 5, and the truss node 1 is fixed; the bar joint 3 and the truss bar 4 are pre-connected as a bar joint assembly 6. The node joint assembly 5 is parallel to the axis of the rod joint assembly 6, and the tooth grooves of the node connector 201 and the rod connector 301 are complementary to each other. At this time, the rod lock tongue 302 pops up, and its side blocks the locking ring 303 from popping up.

[0068] Such as Figure 5 As shown, this example reveals the joint assembly connection process status. The middle part of the truss member 4 is grasped and pressed down by a human hand or a robot hand, and the rod joint assembly 6 is always kept ...

Embodiment 3

[0071] Such as Figure 7 As shown, this example provides a rapid assembly method applicable to the assembly of space truss structures. The method mainly involves the objects including node joint assembly 5, rod joint assembly 6 and space assembly robot 7. The node joint assembly 5 is assembled from the space truss The node (truss node 1) is connected with the node joint 2, and the bar joint assembly 6 is composed of the space truss bar (truss bar 4) and the bar joint 3.

[0072] The space assembly robot 7 grasps the bar joint assembly 6, adjusts the posture so that the interface axes of the bar joint 3 and the node joint 2 are coplanar and parallel, and approaches the node joint 2 along the radial direction of the truss bar 4 to align the interface, When the node joint assembly 5 is coaxial with the rod joint assembly 6, the rod joint 3 and the node joint 2 are automatically locked and connected;

[0073] After the connection is completed, the space assembly robot 7 moves awa...

Abstract

The invention discloses a rapid assembling method suitable for assembling a space truss structure. Firstly, a joint connector assembly and a rod piece connector assembly are formed through connection;the space assembling robot grabs the truss rod piece, adjusts the posture to enable the rod piece connector and the connector axis of the node connector to be coplanar and parallel, gets close to thenode connector in the radial direction of the truss rod piece and enables the connector to be aligned, and after the node connector assembly and the rod piece connector assembly are coaxial, the twoassemblies are automatically locked and connected; and the steps are repeated until the space truss structure is assembled. The rapid assembling method is a truss connecting mode which is convenient to operate, high in rigidity, high in precision and multifunctional, and is suitable for meeting the requirement for on-orbit assembling in future space.

Description

technical field [0001] The invention relates to a construction method of a large aerospace structure, in particular to a rapid assembly method applicable to the assembly of a space truss structure, which only needs to use a single radial insertion of a space robot to realize the smart assembly of a complex space structure. This assembly method is simple in action, suitable for low-consumption and high-efficiency operation of robots and astronauts, and suitable for the assembly and construction of various types of space truss structures, such as future space stations, large-scale antennas, space solar arrays, star bases and other aerospace fields. rail build. Background technique [0002] With the needs of future space exploration, the need for the application of large-scale space structures is becoming more and more urgent, and the scale and requirements of space construction are constantly improving. At present, large-scale space structures are mainly unfolded structures. ...
