Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
A kind of damping device for being able to satisfy inertial alignment requirement is present embodiments provided, it can be in damping state and lock
It is switched between tight state, in locking state, reduces Initial Alignment Error caused by inertial navigation freedom degree.
Inertial navigation is mounted on pedestal 3 by the damping device；As shown in Figs. 1-5, which includes resilient cushion 1, electricity
Magnet 2 and inertial navigation abutting end 4；
Resilient cushion 1 is the block structure with setting thickness of at least two sides setting resilient cushion slot 1-1, when its two opposite sides
When resilient cushion slot 1-1 is arranged, resilient cushion 1 is in " I " fonts；Resilient cushion 1 is horizontally set on the upper surface of pedestal 3；
The number of resilient cushion slot 1-1 corresponds in the number and resilient cushion 1 of inertial navigation abutting end 4, and inertial navigation abutting end 4 is located at
3 upper surface of pedestal, the inside of resilient cushion slot 1-1；
Inertial navigation abutting end 4 is " L " type, including vertical portion and horizontal component, and it is thick that horizontal component thickness is less than resilient cushion 1
Horizontal opening is arranged in degree, horizontal component end, and inertial navigation abutting end through-hole 4- is arranged in the upper surface of the horizontal component of inertial navigation abutting end 4
1, inertial navigation abutting end through-hole 4-1 are the pyramid hole with the opening perforation of the horizontal component of inertial navigation abutting end 4；Two inertial navigations are matched
The vertical portion for closing end 4 is fixedly connected with inertial navigation, and the horizontal component of two inertial navigation abutting ends 4 is located at two dampings of resilient cushion 1
It pads in slot 1-1；
A through-hole is arranged in position corresponding with each inertial navigation abutting end 4 on pedestal 3, and an electromagnetism is arranged in each through-hole
Iron 2；
Each electromagnet 2 passes through corresponding through-hole on pedestal 3, from the horizontal part of corresponding inertial navigation abutting end 4
In the inertial navigation abutting end through-hole 4-1 for the horizontal component that the opening divided horizontally enters into inertial navigation abutting end 4；
Wherein, electromagnet 2 includes: iron core, electromagnet pull rod 2-1, reset spring 2-2 and pull rod boss 2-3, and electromagnet is drawn
Bar 2-1 passes through iron core, and one end and pull rod boss 2-3 are affixed, and the other end is equipped with and its integrally formed shaft shoulder, reset spring
2-2 is sleeved on electromagnet pull rod 2-1, and one end contradicts on the iron core of electromagnet 2, and the other end is contradicted in electromagnet pull rod 2-
On the shaft shoulder of 1 bottom；Pull rod boss 2-3 is prismatic table shape, and electromagnet 2 is not powered on when initial, and pull rod boss 2-3 is located at inertial navigation cooperation
It holds the top of through-hole 4-1 and is located in resilient cushion slot 1-1；After electromagnet 2 is powered, electromagnet pull rod 2-1 pulls back, reset spring 2-
2 are compressed, and pull rod boss 2-3 and inertial navigation abutting end through-hole 4-1 cooperate, and the two upper surface flushes, and resilient cushion slot 1-1 is compressed,
Until abutting end contradicts pedestal 3, in place, inertial navigation abutting end through-hole 4-1 is used to carry out axial lock to pull rod boss 2-3 to arrive for locking
The limit of position.
Specifically: electromagnet 2 is electrically connected with external control unit, for controlling the on/off electricity of electromagnet 2；
When needing to lock inertial navigation and pedestal 3, control unit controls electromagnet 2 and is powered, and the coil inside electromagnet 2 generates
Magnetic field, electromagnet pull rod 2-1 pull back under the influence of a magnetic field, and reset spring 2-2 compression, pull rod boss 2-3 sinks to inertial navigation cooperation
It holds in through-hole 4-1；When the end face of pull rod boss 2-3 is flushed with 4 upper surface of inertial navigation abutting end, inertial navigation abutting end 4 and inertial navigation are locked
It is tightened to position, because electromagnet pull rod 2-1 is aligned with the center of inertial navigation abutting end through-hole 4-1, and 4-1 pairs of through-hole of inertial navigation abutting end
Pull rod boss 2-3 has carried out axial limiting, and such electromagnet 2 can accurately lock inertial navigation after powered up, guarantees inertial navigation and pedestal 3
To connect firmly state, at this point, resilient cushion 1 is compressed.
When needing makes the damping device be in damping state, control unit controls electromagnet 2 and powers off, and magnetic field disappears, electricity
Magnet pull rod 2-1 resets under the action of the elastic force of reset spring 2-2, and pull rod boss 2-3 is detached from inertial navigation abutting end through-hole 4-
1,4 latch-release of inertial navigation abutting end, under the action of the elastic force of resilient cushion 1, inertial navigation rises, and pedestal 3 divides with inertial navigation abutting end 4
From, until inertial navigation rises to initial position, since the freedom degree of inertial navigation is only by the constraint of resilient cushion 1, after power-off, the concussion of pedestal
Inertial navigation will not be passed to by electromagnet 2.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
