A parallel posture adjustment platform with 2 stages of stroke and 6 degrees of freedom in overlapping installation space

Abstract

The invention discloses a 6-degree-of-freedom parallel attitude-adjusting platform with overlapping installation spaces, 2-stage strokes, including 6-degree-of-freedom branch chain legs, a moving platform, a control system cabinet for controlling the movement of the parallel attitude-adjusting platform, and a power supply for the control system cabinet The battery, the 6-DOF branch chain leg includes an X-direction horizontal movement module, a Y-direction horizontal movement module, a Z-direction lifting module and a ball auxiliary leg module, and the Z-direction lifting module is located between the X-direction horizontal movement module and the Y-direction horizontal movement module. In the middle of the mobile module, the control system cabinet realizes the six-degree-of-freedom attitude adjustment of the attitude adjustment platform by controlling the movement of the X-direction horizontal movement module and the Y-direction horizontal movement module and the lift of the Z-direction lifting module. The branch chain legs of the present invention adopt 1 Grade Z to P Z1 Associate and 2nd grade P Z2 The sub-serial stacking stroke meets the demand for super-large posture adjustment space without changing the height and size of the branch chain legs, and realizes six-degree-of-freedom posture adjustment docking and assembly in an ultra-low space.

Description

technical field [0001] The invention belongs to the technical field of butt joint assembly of large and heavy equipment, in particular to a parallel attitude adjustment platform with 2 stages of stroke and 6 degrees of freedom in which the installation space overlaps. Background technique [0002] In the field of aerospace, such as satellite large components, spacecraft cabins, launch vehicles, etc., all involve attitude adjustment and docking assembly of large and heavy components and equipment. The traditional posture-adjusting docking assembly is mainly manual operation with the aid of auxiliary equipment, and the assembly efficiency and precision are low, which has become a bottleneck in the development of the industry. [0003] The butt assembly of large aerospace components needs to be completed by adjusting the six degrees of freedom of the components. At present, in order to realize the 6-DOF movement of the component to be adjusted, that is, the space 3-DOF movemen...

AI Technical Summary

Problems solved by technology

Insufficient structural space is a common problem in existing attitude-adjusting platforms, especially the structural size in the height direction is large and difficult to lower

Large-scale aerospace components are mostly heavy-duty equipment, and the assembly is subject to multiple restrictions such as site size, supporting equipment, and interface height space, so the structural size of the attitude-adjusting platform is also strictly limited
