Description
Technical field
The utility model belongs to Actuator technique field, more particularly to a kind of firer's actuator.
Background technology
Existing firer's actuator only has a push rod, can only provide a kind of unidirectional thrust, therefore, to realize multiple
The motion in direction generally requires multiple actuator, and synchronism is poor, but the synchronism that aerospace field deploys to rudder face has
Higher requirement.After the body of certain model goes out cylinder, four rudder faces of folded state need to be unlocked and deployed in place, it is therefore desirable to
A kind of more push rods and the good firer's actuator of synchronism.
Utility model content
The purpose of this utility model is：The body of certain model is directed to, it is less that design one kind can provide a direction
Releasing force, and can provide five push rod firer's actuator of the larger expansion power in four additional direction.
The technical solution of the utility model is：Five push rod firer's actuator, it includes：Cylinder, the base being connected with cylinder；
Cylinder interior edge axis is provided with upper push-rod, and one end of upper push-rod is fixed at the upper outlet of cylinder by shear pin；
Four side push rods are provided with cylinder circumference same plane, baffle ring, baffle ring are equipped with four side outlets of cylinder
It is connected by steel pin with cylinder；Side push rod shears pin connection with baffle ring by T-shaped；Four side push rods, which are provided with, to be used to be embedded in rudder
The groove in face；
The igniter for being provided with combustion medicine is provided with base, the piston end end of upper push-rod and side push rod is equipped with cushion pad
Circle；Upper push-rod, side push rod, sealing ring is equipped with igniter；
The piston lifting surface area of four side push rods is two times of upper push-rod piston lifting surface area, T-shaped shear pin shearing force
For two times of shear pin shearing force.
Operation principle is：Upper push-rod piston end lifting surface area is the half of four side push-rod piston end lifting surface areas, is cut
The half that pin shearing force is T-shaped shear pin shearing force is cut, after igniter is under fire, high-temperature high-pressure fuel gas enter in cylinder
Chamber, when gas pressure is more than the shearing force of shear pin, shear pin is cut, upper push-rod setting in motion, as defined in moving to
After stroke, four rudder face unblocks；With the gradual increase of gas pressure, when pressure is more than the shearing force sum of T-shaped shear pin
When, T-shaped shear pin is cut, and combustion gas promotes four side push rod setting in motions, simultaneously because the energy accumulation of inner cavity,
The shearing force of T-shaped shear pin is much larger than the frictional force of sealing ring, therefore four side push rods can produce larger output with moment
Thrust, and four side push rods have good synchronism.Therefore, same actuator can export a variety of thrusts.
Beneficial effect：The utility model can provide the different size in five directions and the successively thrust of motion, therefore can
To realize that four rudder faces are first unlocked with less releasing force and then deployed again with larger expansion power reliable synchronization.In addition, this
Utility model original volume is smaller, and larger thrust output can be obtained by less dose, and capacity usage ratio is high.Originally simultaneously
Actuator is provided with buffer gasket, impact when can effectively reduce by five push rods in place.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 AA direction views.
Embodiment
Referring to accompanying drawing 1,2, five push rod firer's actuator, it includes：Cylinder 3, the base 8 being connected with cylinder 3；
The interior edge axis of cylinder 3 is provided with upper push-rod 1, and one end of upper push-rod 1 is fixed on the upper outlet of cylinder 3 by shear pin 2
Place, when initial, upper push-rod 1 is connected with the locking mechanism of four rudder faces, and shear pin 2 plays locking action；
Four side push rods 9 are provided with 3 circumferential same plane of cylinder, baffle ring 11 is equipped with four side outlets of cylinder 3,
Baffle ring 11 is connected by steel pin 10 with cylinder 3；Side push rod 9 is connected with baffle ring 11 by T-shaped shear pin 12；Four side push rods 9
Provided with the groove for being embedded in rudder face；
It is provided with the igniter 6 for being provided with combustion medicine in base 8, the piston end end of upper push-rod 1 and side push rod 9 is equipped with slow
Packing ring 4 is rushed, the material of buffer gasket 4 is soft aluminium, impact when can effectively reduce by five push rods in place；Upper push-rod 1, side push rod 9, igniting
Have and sealing ring 5 is equipped with 6；
The piston lifting surface area of four side push rods 9 is two times of the piston lifting surface area of upper push-rod 1, and T-shaped shear pin 12 is cut
Shear force is two times of the shearing force of shear pin 2.
Further, due to consideration that the position correspondence relation and processing work of base 8 and four side push rods 9 on cylinder 3
Skill, by the way of bolt 7 between cylinder 3 and base 8 connects, and the processing screw thread on base 8 is not used to be screwed into base 8
The mode of cylinder 3；It is interference fit between steel pin 10 and the endoporus of baffle ring 11, coordinates between the endoporus of cylinder 3 for gap, steel pin 10
Position-limiting action is played, side push rod 9 is connected lock side when T-shaped shear pin 12 plays initial with baffle ring 11 by T-shaped shear pin 12
The effect of push rod 9, all of above threaded connection place scribble thread locking glue.
Work process is：When initial, the positive lock of upper push-rod 1, reduce before certain model body goes out cylinder and vibrate to firer
The influence of actuator.After igniter 6 is under fire, actuator intracavitary produces high temperature and high pressure gas, when the pressure of intracavitary is more than shearing
During the shearing force of pin 2, shear pin 2 is cut, the setting in motion of upper push-rod 1, after defined stroke is moved to, four rudder face solutions
Lock；With the gradual increase of cavity pressure, more than T-shaped shear pin 12 shearing force when, T-shaped shear pin 12 is cut,
Combustion gas promotes four setting in motions of side push rod 9, and four side push rods 9 can produce larger thrust output with moment, and four sides push away
Bar has good synchronism；When 1, four side push rod 9 of upper push-rod moves in place, the buffer gasket 4 of stickup at piston end surface
Then can blastic deformation, can effectively reduce the impact in place of five push rods.
