Space load butting locking interface device

Abstract

The invention discloses a space load butting locking interface device and belongs to the technical field of space application equipment. The space loading butting locking interface device comprises an active end and a slave end fixedly connected with an exposed load and a spacecraft cabin body exposed platform. By matching of a main positioning pin, a ball head shear pin and an auxiliary positioning pin at the active end with a main positioning hole, a shear hole, a kidney-shaped shear hole and an auxiliary positioning hole at the slave end, a mechanical arm is guided to operate the exposed load to be butted to a to-be-mounted position. A motor speed reducer at the active end drives a lead screw to drive a main body of a rack A, a branch body of the rack A, a main body of a rack B and a branch body of the rack B to move along a guiding shaft, so that tightening, rigid locking and reliable anti-loosening of the exposed load are achieved. The space load butting locking interface device can assist the mechanical arm to achieve guiding positioning butting, slave capturing, active tightening and rigid locking of the exposed load and a spacecraft cabin body, and accordingly technical support is provided for mounting the exposed load to a set position outside a spacecraft cabin.

Description

technical field [0001] The invention belongs to the technical field of space application equipment, and in particular relates to a space load docking and locking interface device. Background technique [0002] Space vehicles such as space stations and manned spacecraft have arranged a large number of exposure load test platforms on the outer wall of the cabin to expand the exposure test capabilities of space vehicles. At present, the International Space Station has used various forms of payload docking and locking interface devices to support exposure experiment tasks. [0003] However, for the exposed load outside the cabin and the exposed platform outside the cabin, the docking and locking interface device in the prior art cannot automatically capture the exposed load outside the cabin, the degree of automation is not high, the operation ability of the astronaut or the mechanical arm is high, and the mechanism is complicated. Poor maintainability and low reliability. Co...
