Problems solved by technology

The assembly stress caused by gravity cannot be eliminated, which will not only lead to out-of-tolerance assembly accuracy of the product, but also force the stress-concentrated parts, which will eventually affect the unfolding performance and accuracy of the product; at the same time, the assembly stress also directly affects the accuracy of the folded state of the prod

Embodiment

[0034] Such as figure 1 As shown, an integrated device for posture adjustment and unloading efficiency detection for zero-gravity assembly of a space deployment mechanism, the device includes a terminal joint support plate 1, a joint support assembly 3, an arm support assembly 5, a root joint support plate 7 and Data acquisition and processing system 8;

[0035] The space deployment mechanism to be assembled includes an end joint 2 , an arm 4 and a root joint 6 .

[0036] There is a reference hole "O" on the flange surface of the root joint 6, and a reference hole "R" on the flange surface of the end joint 2. The assembly accuracy of the space expansion mechanism is adjusted by adjusting the reference hole "R" relative to the reference hole "O". It is guaranteed by the spatial position relationship, which is characterized by the transfer matrix.

[0037] Such as Figure 5 As shown, the end joint support plate 1 is used to simulate the installation interface of the end joint...

Abstract

The invention relates to a posture adjustment and unloading efficiency detection integrated device, in particular to the posture adjustment and unloading efficiency detection integrated device for space expansion mechanism zero-gravity assembling and ground zero-gravity assembling for space high-precision complex expansion mechanisms, and belongs to the technical field of space expandable mechanism precision assembling. Through a tail end supporting plate and a root supporting plate, a complex assembling reference on a space expansion mechanism is ingeniously transferred, an assembling method is improved, and assembling efficiency is improved. Multi-freedom-degree posture adjustment on joint space postures of the space expansion mechanism is achieved in the mode of combining a plurality of joint supporting components. Unloading force is detected online in the assembling process through a sensor and a data collecting and processing system, and stabile and reliable unloading efficiency in the assembling process is guaranteed. An air foot and rolling bearing mode is adopted, the assembling stress of the space expansion mechanism is effectively reduced, and assembling precision is improved.

Description

technical field [0001] The invention relates to an integrated device for posture adjustment and unloading efficiency detection, in particular to an integrated device for posture adjustment and unloading efficiency detection for zero-gravity assembly of a space deployment mechanism, and a ground zero-gravity device for a space deployment mechanism with high precision and complexity The unloading assembly belongs to the technical field of precision assembly of space expandable mechanisms. Background technique [0002] Zero gravity, also known as weightlessness or reduced gravity, is one of the most important features of the space environment. Before space systems such as satellites, aircraft and space stations fly in orbit, in order to ensure the high precision and reliability of the system, it is necessary to conduct dynamic tests on the subsystems of the space mechanism on the ground. However, the gravitational environment of the ground makes it impossible to obtain the per...
