Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] figure 1 It is a schematic diagram of an active mechanism capturing a passive structure according to an embodiment of the present invention. The passive structure 1 is composed of the active mechanism 2, and the active mechanism 2 is installed at the end of the space manipulator. When the space manipulator carries the active mechanism 2 gradually approaching the passive structure 1, the active mechanism 2 captures the passive structure 1, and completes the preliminary correction of the circumferential deviation by relying on the wedge-shaped groove configuration of the passive structure 1; after the capture is completed, the active mechanism 2 snaps Tighten the inclined surface of the boss of the passive structure 1, and continue to pull down until the butt joint surfaces between the mechanisms are completely attached. At this time, the...

Abstract

The invention provides a space capturing and locking device. The space capturing and locking device comprises a driving structure and a driven structure. The driving structure comprises a shell assembly, a driving assembly, a transmission assembly, an upper plate auxiliary assembly and three sets of finger assemblies. The shell assembly is used for supporting and being connected with the driving assembly, the transmission assembly, the upper plate auxiliary assembly and the finger assemblies. The upper plate auxiliary assembly comprises rollers. The finger assemblies comprise four-bar mechanisms. The driving assembly drives the transmission assembly, the transmission assembly converts rotational motion into linear motion, the transmission assembly controls the finger assemblies to move upwards and downwards, the three sets of finger assemblies are closed due to compression of the rollers when moving downwards, and then the driven structure matched with the driving structure is clamped. The four-bar mechanism is in linkage when the finger assemblies move upwards, the finger assemblies are driven to be opened, and then the driven structure is released. The space capturing and locking device can be used for capturing and locking of a space mechanical arm on a small aircraft, and the advantages of being low in weight, small in size, large in tolerance and diverse in capture object are achieved.

Description

technical field [0001] The invention relates to the technical field of designing space operations, and in particular relates to a capture and locking device for a space manipulator, which can capture, lock and release small space vehicles and loads. Background technique [0002] The terminal operating tool of the space manipulator is the executive mechanism for the manipulator to complete a series of space tasks. According to the types of tasks completed, the types of space mechanisms are also various. With the increase in the number of human satellite launches year by year, the number of abandoned satellites in space is also showing an accelerating trend. At present, there is no effective method for recycling abandoned satellites. Therefore, it is necessary to design a capture mechanism suitable for small space satellites. , used to implement the spatial capture operation. Contents of the invention [0003] In order to solve the problem that the current space satellites ...
