Description
Technical field
The present invention relates to inertial navigation frames to rotate control technology field, and especially a kind of effectively triggering microswitch is simultaneously protected
Protect the stop mechanism of electrical component.
Background technique
Frame rotation is the important method of inertial navigation set platform stable or error modulation.For around axis continuous rotation frame
Signal transmission between frame is usually realized by mechanical conductive slip ring, as shown in Figure 1, interior sash frame member 2 passes through torque motor
The driving of part 3 rotates in external frame unit 1 around Rotating shafts 4, at this point, being equipped with mechanical conductive slip ring in Rotating shafts 4, not
Install the stop mechanism being made of part 5 and part 6 additional.
But mechanical conductive slip ring is first is that expensive, second is that causing to set since integrity problem often occurs in spin friction
Standby failure, so, in order to reduce equipment cost and improve equipment dependability, leading to for not needing the frame around axis continuous rotation
Often withouyt mechanical conductive slip ring, but flexible circuit conductor transmission signal is directlyed adopt in Rotating shafts 4.At this point, to prevent soft lead
Line excessive distortion breaks down, it is necessary to take necessary limit stops measure.The stop mechanism that part 5 and part 6 are constituted in Fig. 1 can
Occur with limiting frame around 360 degree of continuous rotations of axis, general stop mechanism scheme has: part 6 is cylinder backstop pin member 7, and part 7 is direct
It is installed in interior sash frame member 2, part 5 is mechanical stop boss part 8, and part 8 regards backstop range and as one or two pieces and can be installed on
In external frame frame member 1, mechanical stop (such as Fig. 2) by force is realized；Or part 5 is become into the electrical backstop that microswitch part 9 is realized
Scheme (such as Fig. 3).
Scheme shown in Fig. 2 is that cylinder backstop pin member 7 touches after mechanical stop boss part 8 backstop by force.This scheme is maximum
The drawbacks of be the absence of power-off protection signal, rotating frame under the drive of torque motor part 3 by backstop by force after can only be in electric-controlled
Power-off protection, poor reliability, torque motor part 3 easy to damage are realized on circuit processed by judging 3 moment variations of torque motor part
And stop configurations part even frame.
Scheme shown in Fig. 3 triggers microswitch part 9 by cylinder backstop pin member 7 and realizes the triggering of power-off protection signal, can have
Effect protection torque motor part 3.But microswitch part 9 very rapid wear itself (is made and nonmetallic conjunction of macromolecule polymer material
Gold is made, and belongs to fallible component), interior sash frame member 2 hits microswitch part under the drive of torque motor part 3 with certain speed
9 easily cause its damage.
Fig. 4 is that a kind of mechanical, electrical coordination of Project Cooperation prototype design stage design of the present invention production uses backstop side
Case, cylinder backstop pin member 7 realize that 3 power-off protection of torque motor part, interior sash frame member 2 are made in inertia after triggering microswitch part 9
Cylinder backstop pin member 7 after a low-angle of reruning under contacts realization mechanical stop by force with mechanical stop boss part 8.The program
Although the damage problem of torque motor and microswitch to a certain extent, it has also been found that having the disadvantage that in assembly use:
First is that realize effective triggering of microswitch part 9, that is, the actuating length range for meeting microswitch part 9 is (small size, accurate micro-
For the actuating length range of dynamic switch generally in 0.3~0.6mm, trigger range is very narrow), it is necessary to control size H well, and H by
2 radius of gyration R (generally reaching 200~300mm) of interior sash frame member, 7 diameter of phi of cylinder backstop pin member and microswitch part 9 are real
The influence of contact geometrical extension L, tolerance will control extremely difficult within the scope of 0.3mm when border is triggered, and be difficult effectively to trigger micro-
Dynamic switch member 9, i.e. actuating length cannot not enough trigger, and actuating length is excessive will directly to damage microswitch contact；Second is that micro-
The triggering of dynamic switch member 9 is laterally to trigger, reliable trigger itself is with regard to poor.
Summary of the invention
In place of making up the deficiencies in the prior art, one kind effectively triggering microswitch is provided and is protected
The stop mechanism of electrical component, this programme guarantee fine motion while reducing part machining and assembly precision requires well
Switch motion stroke range, it is accurate to trigger, it realizes effective backstop between rotating frame, simultaneously effective protects microswitch, power
The electrical components such as torque motor are from damage.
