Breaking-in tool for spacecraft ground and on-rack fasteners

Abstract

The invention discloses a breaking-in tool for spacecraft ground and on-rack fasteners. The breaking-in tool mainly comprises a dust suction device, a handheld drilling device and a redundancy control box, wherein a dust suction pipe of the dust suction device is communicated with the interior of a box body of the redundancy control box through a connector arranged on the side face of the redundancy control box to ensure that powdered scraps can be effectively sucked into the dust suction device without diffusing; the top of the redundancy control box is provided with a hole so that a drill bit of the handheld drilling device can extend into the redundancy control box to break in and damage the fasteners; the redundancy control box is made of transparent organic glass, and multiple layers of brushes are arranged on the inner side of the box body of the redundancy control box and surrounding the hole in the top to tightly attach to the drill bit of the handheld drilling device and prevent the powdered scraps from diffusing out. The breaking-in tool achieves the technical effect of breaking-in of the fasteners in a confined space and a pollution-sensitive environment, achieves clean dismantling of the fasteners in an abnormal state, and meets the demand for assembly of the spacecraft ground and on-rack fasteners.

Description

Technical field [0001] The invention belongs to the technical field of spacecraft ground machinery, and in particular relates to a demolition tool, which uses a dust suction device, a surplus control box and a hand-held drilling device to destroy abnormal fastener nuts, thereby realizing fastener removal Features. Background technique [0002] At present, the transfer of cargo on the manned spacecraft and the maintenance and replacement of equipment on orbit involve the removal of fasteners. Due to the combined effects of structural deformation, fastener anti-loosening glue curing, fastener corrosion and other factors, there is a certain probability of occurrence Fasteners “seize” and rounded nuts cause the problem of fasteners that cannot be removed. For this reason, fasteners need to be destructively removed. For manned spacecraft fasteners, the following difficulties need to be addressed: [0003] Strict requirements for the control of redundant objects: Manned spacecraft has s...
