Description
Technical field
The invention belongs to space optical remote fields, are related to a kind of active expansion locking mechanism.
Background technique
With being constantly progressive for space optical remote technology, deployable optical system have become the technical field development must
Right trend.How to realize and be accurately unfolded and lock after each element of optical system is entered the orbit, be deployable optical system face one
Big challenge.Currently, commonly expansion locking mechanism is passive type locking mechanism, between the pressing force or component that generally rely on spring
Frictional force locks to realize.Although this locking means have many advantages, such as that structure is simple, light weight, are easily achieved, due to quilt
The coupling mechanism force that dynamic formula locking mechanism generates is smaller, it is difficult to eliminate fit-up gap, be insufficiently resistant to opposite force, therefore by opposite force
Shaking can be generated when effect, influence positioning accuracy.
Summary of the invention
In order to solve the problems in the existing technology, the present invention provides a kind of active Double-conical-surfaces, and locking machine is unfolded
Structure solves the problems, such as that passive type locking mechanism coupling mechanism force is small, poor anti jamming capability.
The technical proposal for solving the technical problem of the invention is as follows:
A kind of active expansion locking mechanism, the mechanism include: outer positioning seat, lock out motor, probe, interior positioning seat, row
Cheng Kaiguan；The lock out motor is arranged in outer positioning seat, and outer positioning seat is connected with structure to be deployed；The probe and locking electricity
Machine connection；Outer positioning seat, lock out motor and probe are structure as a whole；The travel switch is arranged in interior positioning seat, and default
It is fixed on fixed structure jointly in the seat of position；It is concave structure in the interior positioning seat, recess is check valve；The probe
Upper setting foil gauge；
The outer positioning seat drives structure to be deployed to move upwards, and when mechanism to be deployed is fully deployed, probe passes through interior
The check valve of positioning seat continues up after entering interior positioning seat inside；When probe touches travel switch, lock out motor
Starting, pulls downward on probe, is allowed to move downward；And then probe is contacted with check valve, and generates normal pressure；Due to probe without
Method is again by check valve, so that lock out motor drives outer positioning seat to move upwards；When outer positioning seat and interior positioning seated connection touch simultaneously
Normal pressure is generated, probe interior then generates pulling force and deformation, and after the strain that foil gauge measures, lock out motor stops working, power-off
Locking, to realize the expansion locking of total.
The beneficial effects of the present invention are: positioning of the present invention by the way of Double-conical-surface cooperation, after effectively increasing expansion
Precision；In such a way that active is locked, it is possible to provide biggish pretightning force effectively eliminates gap, improves optical element exhibition
Anti-interference ability after opening.The present invention can be used for the fields such as the expansion locking of deployable optical system.

Specific embodiment
The present invention is described in further details with reference to the accompanying drawings and examples.
As shown in Figure 1, locking mechanism is unfolded in a kind of active Double-conical-surface, includes outer cone positioning seat 1, lock out motor 2, visits
Needle 3, inner cone positioning seat 4 and travel switch 5.Outer cone positioning seat 1 is mounted in structure 7 to be deployed, and lock out motor 2 is mounted on outer cone
Inside positioning seat 1, probe 3 is mounted on 2 front end of lock out motor, and inner cone positioning seat 4 is mounted on fixed structure 6, and travel switch 5 is pacified
On fixed structure.As shown in Fig. 2, outer cone positioning seat 1 includes male cone (strobilus masculinus) 1-1, pedestal 1-2, wherein pedestal 1-2 in structure
With flexible slot 1-3；As shown in figure 3, including syringe needle 3-1, shank 3-2 and the strain being arranged on shank 3-2 in 3 structure of probe
Piece 3-3, syringe needle 3-1 are cone structure.As shown in figure 4, include inner conical surface 4-1 and check valve 4-2 in 4 structure of inner cone positioning seat,
Wherein check valve 4-2 has flexible slot；Male cone (strobilus masculinus) 1-1 is consistent with the taper of inner conical surface 4-1, axis be overlapped, and with knot to be deployed
The structure direction of motion is parallel.
After remote sensor is entered the orbit, fold locking mechanisms unlock, structure 7 to be deployed starts in the case where motor driven is unfolded along straight line side
To expansion, close to before the state being fully deployed, probe 3 passes through inner cone positioning seat 4 and has check valve 4-2 flexible, enters
Inside inner cone positioning seat 4, the limit switch 5 inside inner cone positioning seat 4 is touched later, and expansion motor stops working, lock out motor 2
It starts to work.Lock out motor 2 pulls probe 3, is allowed to move backward, and and then 3 syringe needle bottom of probe is contacted with check valve 4-2,
And apply downward pressure to check valve 4-2.Since probe 3 can not exit check valve 4-2, so that lock out motor 2 drives therewith
Connected outer cone positioning seat 1 starts to travel forward, and final outer cone positioning seat conical surface 1-1 is contacted with inner cone positioning seat conical surface 4-1, and
Normal pressure is generated, lock out motor 2 can not continue up, but lock out motor 2 still pulls downward on probe 3, at this time probe 3
Shank 3-2 inside then generate pulling force.Lock out motor 2 continues to pull back probe 3, and the pulling force inside shank 3-2 constantly increases, and draws
Power is deformed probe shank 3-2, and this displacement transfer gives foil gauge 3-3, reaches certain to the foil gauge 3-3 strain measured
After amplitude, lock out motor 2 stops working, power-off locking, to realize the expansion locking of total.
By to male cone (strobilus masculinus) 1-1 and inner conical surface 4-1 is ground, making the two taper consistent, taper-face contact area is greater than the gross area
80%.
Outer cone positioning seat 1 is made of TC4 material, and probe 3 is made of TC17 material, and inner cone positioning seat 4 uses TC4 material
Material is made.
Above description, only the embodiment of the present invention, embodiment rather than limiting the invention；All engineerings for being familiar with the field
Personnel, the other equivalence changes made, such as the selection of size, material, change in shape, should all cover in institute Shen of the present invention
It please be in the scope of the patents.
