Problems solved by technology

The use of robots to complete the installation of the truss structure has high requirements for the operation and control of the robot itself, especially in the process of installing and fixing the truss members, which often requires precise cooperation between multiple robots, which greatly increases the difficulty of robot operation. And it is easy to cause accidental risk

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] A self-locking joint used for the connection of space truss structures comprises a petal joint, a rotatable joint, two spring buttons and a bullet joint.

[0031] The petal joint includes an adapter piece 1 and an adapter piece. A through hole is provided in the center of the adapter piece 1 (1), and a through hole is provided in the middle of the adapter piece. Two bosses are arranged on the outer wall of the adapter piece, and the two bosses There is a 90-degree angle between the platforms, and a groove (3) is opened on each boss away from the through hole, and through holes are opened on the side walls on both sides of the groove, and the two through holes are coaxial, and the two bosses The plane formed by the axis of the through hole is perpendicular to the axis of the through hole in the middle of the adapter. A truss member is inserted int...

Abstract

The invention provides a self-locking joint used for the connection of space truss structures. The bullet joint is inserted into the shelter, the trapezoidal protrusion of the bullet joint matches the trapezoidal through hole on the bottom surface of the shelter, and the arc of the bullet joint The shaped bullet is first compressed and then bounced, and finally locked in the square holes on the left and right sides of the shelter to complete self-locking. When it is necessary to unlock, push the two cross buttons that press the spring button until the actuating block of the cross button squeezes The arc-shaped bullet is retracted into the bullet joint, and the unlocking can be completed, and the truss member connected with the bullet joint is taken away. The invention can change the direction of the rotatable joint, and can further flexibly adjust the installation direction of the rod; it can reduce the operation accuracy and difficulty required by the robot, and can complete the automatic locking of the two parts, and the unlocking process can be completed through the spring button structure. The functions of automatic locking and disassembly separation during the installation process are completed, which is convenient for the robot to operate.

Description

technical field [0001] The invention relates to the field of mechanical design and processing, in particular to a self-locking joint device. Background technique [0002] Due to the limitations of the volume and carrying capacity of the launch vehicle, large structures in space, such as solar power plants, large communication antennas, and space stations, cannot be sent into space in one launch. This requires multiple launches and then assembly on the space station, and the support structure of these large spacecraft is mainly a truss structure. The research status and development trends related to construction technology show that there are certain limitations in human on-orbit assembly. On-orbit assembly by someone is only capable of small tasks, short time, and relatively simple assembly tasks. For future space assembly tasks with complex structures, huge volumes, harsh installation environments, and high precision requirements, manned assembly cannot meet the task requ...
