Abstract

The invention provides a thermal control multi-layer puncher for spacecraft, which is characterized in that it includes a handle, a screw, a butterfly nut, a cylindrical base, a needle, and a scale; one end of the screw is wrapped by the handle, and the other end of the screw is set There is a central hollow area, the other end surface of the screw is provided with threads, the needle is inserted into the central hollow area, the wing nut and the cylindrical base are tightly connected with the screw through the threads, and a scale is provided on the threads. The invention is light and easy to hold, simple in structure, convenient in operation, and easy to popularize; the head of the screw is hollowed out to realize the design of replaceable needles, which is convenient for maintenance; the needles are made of stainless steel, high-strength and corrosion-resistant; Arbitrary aperture; the screw thread adopts fine thread, which has self-locking characteristics, and the depth of the needle hole can be adjusted; the cylindrical base is made of brass material with a large bottom area, which meets the requirements of dispersing pressure and the bottom surface is evenly stressed, and has self-seeking verticality when drilling. ability.

Description

technical field [0001] The invention relates to the field of aerospace thermal control, in particular to a thermal control multi-layer puncher for spacecraft. Background technique [0002] At present, the space propulsion sub-system needs thermal control wrapping. In order to avoid the phenomenon of vacuum degassing in the thermal control wrapping in a vacuum, it is necessary to carry out opening work. At present, scissors are mostly used for opening holes. Since the thermal control thickness of each spacecraft is different, the depth of the opening cannot be controlled when using scissors, which is easy to damage the surface of the spacecraft. In addition, there may be interference from other components in the thermal control area, and common tools such as scissors cannot be used. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide a thermal control multi-layer puncher for spacecraft. [0004] Acco...
