Multi-degree-of-freedom assembling system suitable for large size equipment assembly in cabin of spacecraft

Abstract

The invention discloses a multi-degree-of-freedom assembling system suitable for large size equipment assembly in cabin of a spacecraft. The system comprises a small arm drive, a large arm drive, a lifting mechanism, a vertical rail, a swing mechanism, a base, a horizontal rail and a tail end executing function mechanism. A horizontal sliding block device is connected with a guide rail above the horizontal rail, so that the movement of the base and the whole mechanism borne by the base in the horizontal direction is realized; a slewing bearing is fixed to the upper surface of the base, the vertical rail is fixedly connected to the slewing bearing of the swing mechanism, and the large arm drive is installed on the longitudinal guide rail through a vertical sliding block device and moves inthe vertical direction. The lifting mechanism is fixedly connected to the other opposite side face of the vertical rail, overall rotary motion is achieved through a gear installed in a winding drum, the small arm drive is connected with the large arm drive through a turbine speed reduction device, and the small arm drive is used for driving the tail end executing function mechanism to execute actions. According to the invention, the risk of easy shaking in the hoisting process is overcome, the safety is high, the manual labor is reduced, and the assembly agility and safety of the product are improved.

Problems solved by technology

[0002] In the existing technology, first of all, the assembly of aerospace products mainly relies on manual operation, which leads to the quality of assembly heavily depending on the assembly technology and experience of the operator, which has a large subjective error and is time-consuming. force, which is not conducive to the completion of assembly work with quality and quantity

Secondly, the assembly process of aerospace products requires simple process equipment such as spreaders and support vehicles as tools for positioning and support. These process equipment are heavy and have poor precision, and there are problems such as unquantifiable component pose adjustment and low positioning accuracy.

At the same time, during the final assembly process of the manned space station project, there are many large and heavy loading equipment in the cabin. Due to their heavy weight and limited installation space, these loading equipment cannot be transported manually under the existing technology. For installation. It is necessary to borrow a certain labor-saving device

[0003] Finally, with the arrival of the final assembly task of the new space station system, the functions of the final assembly products tend to be integrated, the size is getting larger and heavier, and the diversification of the spacecraft body configuration makes the final assembly work conditions more complicated, which has exceeded the current In the stage technology, the manual lift or lifting method can be competent

[0004] At present, heavy-weight products of spacecraft can be assembled by hoisting, but in the cabin, the assembly of heavy-weight equipment products usually adopts the "hanging" hoisting assembly scheme. In the space, heavy products are hoisted by hanging, and the moving direction and reliability are poor

The adjustment of each position and angle depends entirely on the experience and cooperation of the operators, and cannot be quantified and controllable

The weight of the product is carried by hoisting, it is easy to shake during the assembly process, and it is easy to collide with other parts, and the safety is poor.
