Abstract
The invention discloses a handheld type multiple-layer perforating device for a satellite and relates to a perforating device. The handheld type multiple-layer perforating device for the satellite comprises a pressing head, a perforating spring, guide pins, an aligning needle fixing pin, a cutter head, a crash pad, a reset spring, an outer sleeve, an aligning needle, an aligner base and an aligner. The aligner is fixedly arranged on the aligner base through screws, the guide pins are arranged at one end of the cutter head, the aligning needle is arranged in the cutter head through the aligning needle fixing pin, the reset spring is arranged at the other end of the cutter head through the crash pad, the outer sleeve is arranged on the outer side of the reset spring, the aligning needle is arranged in the crash pad, the reset spring, the outer sleeve, the aligner and the aligner base in a penetrating mode in sequence, the pressing head is connected between the outer sleeve and the cutter head in a sleeved mode, and the perforating spring is arranged in the pressing head. The handheld type multiple-layer perforating device for the satellite is simple and reliable in structure, convenient to operate, free of influences of the thickness of multiple layers, wide in range of application, especially suitable for the situation that perforating positions of the upper face and lower face of a multilayer thermal insulation assembly of a large area cannot be aligned easily and high in perforating efficiency, parts of the device are easy to machine, and mounting and dismounting are convenient.
Description
technical field [0001] The invention relates to a punching device, in particular to a multilayer punching device for a hand-held satellite. Background technique [0002] The surface of the satellite needs multi-layer heat insulation components (referred to as multi-layer) to achieve heat preservation. In order to facilitate the extraction of various wiring, it is necessary to punch holes in the multi-layer. The multi-layer is composed of many layers of polyimide film, nylon screen, and double-sided aluminized polyester film. It is thicker and fluffy with a larger surface area. The ordinary punching device cannot meet the punching requirements. [0003] At present, needle piercing is used in production to obtain threading holes. Since flashes and sharp cracks are generated when multi-layer materials are pierced, large-area damage is easily caused when multi-layers are tensioned, resulting in waste, rework and The problem of inefficiency. Therefore, the best method for multi...
