Mounting-space-superposed, two-stage-stroke and six-degree-of-freedom parallel posture adjusting platform

Abstract

The invention discloses a mounting-space-superposed, two-stage-stroke and six-degree-of-freedom parallel posture adjusting platform. The mounting-space-superposed, two-stage-stroke and six-degree-of-freedom parallel posture adjusting platform comprises a six-degree-of-freedom branched chain leg, a movable platform, a control system cabinet for controlling the parallel posture adjusting platform tomove and a power storage battery for providing power for the control system cabinet. The six-degree-of-freedom branched chain leg comprises an X-direction horizontal moving module, a Y-direction horizontal moving module, a Z-direction lifting module and a ball pair supporting leg module. The Z-direction lifting module is located between the X-direction horizontal moving module and the Y-directionhorizontal moving module. The control system cabinet controls movement of the X-direction horizontal moving module and the Y-direction horizontal moving module and lifting of the Z-direction liftingmodule, and six-degree-of-freedom posture adjusting of the posture adjusting platform is achieved. According to the mounting-space-superposed, two-stage-stroke and six-degree-of-freedom parallel posture adjusting platform, strokes are connected in series and superposed for the branched chain leg by a first-stage Z-direction PZ1 pair and a second-stage PZ2 pair, on the basis that the height size ofthe branched chain leg is not changed, the requirement for an ultra-large posture adjusting space is met, and six-degree-of-freedom posture adjusting butt joint and assembling in an ultra-low space are achieved.

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
