Embodiment 1

[0020] like Figure 1-4 As shown, an electromagnetically driven non-fire separation device based on a scroll spring transmission assembly, the separation device includes three parts: a split nut part, a scroll spring slow release structure, and an electromagnet release structure part, characterized in that: The split nut part includes an upper block 10, a split nut 6, a nut compression spring 12, a lower block 11, a bottom plate 7, and a bolt 8; the scroll spring slow-release structure includes a scroll spring 5 and a rotating disc 9; the electromagnet releases The structural part includes a rotating electromagnet 1 , a blocking column 2 , a release compression spring 3 , and a release pin 4 .

[0021] The split nut is in contact with the bottom plate 7, the lower end is restricted by the lower block 11, and the upper end is restricted by the upper block 10, so that the split nut 6 can only move in the radial direction, and a nut is installed between the split nuts 6. The com...

Abstract

A solenoid-actuated non-pyrotechnic separation device based on a volute spiral spring transmission assembly is provided. A volute spiral spring slow-release structure is employed to limit a segmentednut, and during unlocking, slow release is carried out for unlocking in the unlocking process, thereby effectively reducing impact response. An electromagnet is adopted as a driving source to provideunlocking power for the whole mechanism, and no pollution, detectability and measurability are achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical device mechanisms, and relates to an electromagnetically driven scroll spring separation nut device. The separation nut device is a detectable and detectable separation device, and has the advantages of no pollution, high reliability, strong environmental adaptability, and high load-bearing capacity. and low impact advantages. Background technique [0002] The main function of the separation device in the spacecraft is to reliably connect the two bodies to be separated before the separation action is performed, and can quickly cut off the connection between the two separated bodies when the separation sequence is received. Separation devices are mainly divided into two types: line type and point type. The former includes energy-gathering cutting cables, flexible detonating cables, expansion tubes, wrapping tapes, air bags, etc., while the latter includes explosive bolts, separation nuts, and th...
