Abstract
The invention discloses an electromagnetic type separation device and belongs to the technical field of point type separation devices. The device comprises a cover body, an electromagnet, a hoop, a split nut, a connecting bolt and an acquirer. Peripheral equipment comprises an upper connector and a lower connector which need to be separated. The cover body is fixedly connected with the upper connector, and the electromagnet is fixedly connected at the inner part of the cover body. The acquirer is fixedly connected to the lower connector. One end of the connecting bolt is connected with the split nut in a screwing manner after penetrating through via holes of the upper connector and the lower connector. The hoop is arranged at the outer part of the split nut in a sleeving manner so as to limit the separation of the split nut in the radial direction. The other end of the connecting bolt is fixedly connected with the acquirer. A compressed spring is arranged on the outer peripheral surfaces of the electromagnet and the hoop in a sleeving manner, and two ends of the compressed spring are separately pressed against the inner surface of the cover body and the hoop. When the electromagnet is electrified, the hoop moves towards the electromagnet and relieves limitation on the split nut, and the bolt moves downwards, so that the separation of the upper connector and the lower connector is realized.

Device used.As the segregation apparatus used the earliest, point type segregation apparatus is widely used in guided missile, rocket etc.
Play each section of rocket body structure aircraft connection with separate.Along with the development of modern space technology, point type is divided
Demand from device performance improves further.The point type segregation apparatus used on aerospace craft at present is most
It is Fire load, has the disadvantage in that when Fire load works big to the impulsive force load of structure.Firer fills
Putting stored energy big, speed of action is fast, causes shock loading during gunpowder explosion produced whole mechanism
Greatly；Can not reuse.Owing to gunpowder explosion produces destruction to structure, most Fire load can only use one
Secondary；Pollute bigger.Fire load relies on the blast of gunpowder or burning pushing mechanism to complete separation function, its
Blast or the harmful gas of burning generation and fragment etc. pollute spatial environments.
Summary of the invention
In view of this, the invention provides a kind of electromagnetic type segregation apparatus, device utilizes electric magnet to provide suction,
Realize device by a point lobe nut to connect and the function separated simultaneously.
A kind of electromagnetic type segregation apparatus, this device includes lid, electric magnet, cuff, point lobe nut, connection
Bolt and grabber, ancillary equipment is to need the upper connector of separation and lower connector；
Described lid is fixing with upper connector to be connected, and electric magnet is fixedly connected on lid portion inside, and grabber is fixed
Be connected on lower connector, one end of described connecting bolt through after the via of upper connector and lower connector with
Dividing lobe nut to screw, cuff is sleeved on a point lobe nut outside limits and divides lobe nut to be radially separated, connecting bolt
The other end and grabber fixing be connected；Described compression spring sleeve is contained on the outer circumference surface of electric magnet and cuff, and two
End is conflicted with lid inner surface and cuff respectively, and electric magnet is when energising, and cuff moves towards electric magnet direction
And release the constraint to point lobe nut.
Further, for the ease of installation and removal, described lid is made up of bottom and top cover, described bottom
The horizontal convex edge of bottom surface and cuff fixing be connected, described electric magnet is fixedly connected on the inner surface of top cover.
Further, described grabber includes capturing sleeve, packing ring, power assistant spring and nut；Described capture
One end of sleeve is fixing with lower connector to be connected, the end face of the other end and washer contacts, nut and connecting bolt
The threaded one end being positioned at lower connecting plate side coordinates and packing washer, and power assistant spring is sleeved on packing ring outer circumference surface
On, two ends are inconsistent with the horizontal convex edge of the end face of capture sleeve and packing ring respectively.
Further, in order to reduce the frictional force produced when cuff separates, the inner periphery of cuff with point lobe nut
It is machined with annular groove arranged side by side on the outer circumference surface of face and point lobe nut.
Beneficial effect:
Present invention utilizes a point architectural characteristic for lobe nut, i.e. in the case of affined can and plain nut
Equally screw with bolt, can radially scatter and separate with bolt after constraint relief.Its simple in construction, separates
Rapidly, reusable.Utilize simultaneously electric magnet as provide separating force parts, compared to tradition firer
Segregation apparatus, during separation, impulsive force, pollution, cost all decrease.

Detailed description of the invention
Develop simultaneously embodiment below in conjunction with the accompanying drawings, describes the present invention.
As shown in Figure 1, the invention provides a kind of electromagnetic type segregation apparatus, a kind of electromagnetic type segregation apparatus,
This device includes upper connector 9 and lower connector 10, bottom 1, stage clip 2, top cover 3, the electricity that needs separate
Magnet 4, screw 5, cuff 6, point lobe nut 7, connecting bolt 8, capture sleeve 11, packing ring 12, help
Power spring 13 and nut 14；
As shown in Figure 2, a point lobe nut 7 is made up of pintongs, is the nut of a complete structure after closing up,
For the frictional force produced when reducing separation, the outer circumference surface of point lobe nut 7 is machined with multiple cannelure.
The bottom surface of bottom 1 is fixed with the horizontal convex edge of cuff 6 and is passed through the horizontal convex edge of bottom 1 after being connected with upper
Connector 9 is fixing to be connected, and electric magnet 4 is fixedly connected on the inner surface of top cover 3, one end of capture sleeve with
Lower connector 10 is fixing to be connected, and the end face of the other end contacts with packing ring 12；One end of connecting bolt 8 passes
Screwing with a point lobe nut after the via of upper connector 9 and lower connector 10, cuff 6 is sleeved on a point lobe nut 7
Outside limits divides lobe nut to be radially separated, the other end of connecting bolt 8 with by nut packing washer 12,
Power assistant spring 13 is sleeved on packing ring 12 outer circumference surface, two ends respectively with the capture end face of sleeve 11 and packing ring
Horizontal convex edge inconsistent；Stage clip 2 is sleeved on the outer circumference surface of electric magnet 4 and cuff 6, and two ends are respectively
