Thermal control multilayer puncher for spacecraft

Abstract

The invention provides a thermal control multilayer puncher for a spacecraft, which is characterized by comprising a handle, a screw rod, a butterfly nut, a cylindrical base, a needle head and a scale; wherein one end of the screw rod is wrapped by the handle, the other end of the screw rod is provided with a central hollow area, the surface of the other end of the screw rod is provided with threads; the needle head is inserted into the central hollow area; the butterfly nut and the cylindrical base are fixedly connected with the screw rod through the threads, and the scale is arranged on thethreads. The puncher provided by the invention is light, easy to hold, simple in structure, convenient to operate and easy to popularize; the head of the screw rod is hollow to realize the design of the replaceable needle head; the head of the screw rod convenient for maintenance; the needle head is made of stainless steel and has high strength and corrosion resistance; the point of the needle head has various specifications and can punch holes of any aperture; the threads of the screw rod are fine threads with self-locking property; the depth of the point can be adjusted; the cylindrical baseis made of brass material and has a large bottom area, so the cylindrical base can meet the requirement of pressure dispersion, and the bottom surface is stressed evenly; and the cylindrical base iscapable of finding perpendicularity during drilling.

Description

Technical field [0001] The invention relates to the field of aerospace thermal control, in particular to a thermal control multilayer perforator for spacecraft. Background technique [0002] At present, the space propulsion sub-systems need to carry out thermal control packages. In order to avoid the phenomenon of vacuum deflation of thermal control packages in the vacuum, opening work must be carried out. At present, most of the holes are opened by scissors. Due to the different thermal control thickness of each spacecraft, the opening depth cannot be controlled when using scissors, and it is easy to damage the surface of the spacecraft. In addition, other components may interfere with the thermal control area, and common tools such as scissors cannot be used. Summary of the invention [0003] Aiming at the defects in the prior art, the purpose of the present invention is to provide a thermally controlled multilayer perforator for spacecraft. [0004] According to the present inv...
