Description
Technical field
The invention relates to the mechanical lock that is applied in the plane hydraulic system pressurized strut, more particularly, the invention relates to a kind of Novel clamp ring lock that can be integrated in the pressurized strut.
Background technique
In modern actuating system, there are a lot of places need to be after actuating system runs out of steam, the special machine device by self configuration is locked in securely some specific position with actuating system, and can resists external loading.Therefore in the most plane hydraulic system actuator, in the widely used pressurized strut, nearly all be integrated with the scheme of inside and outside mechanical lock.At present, the mechanical lock that uses in aviation mainly contains two kinds: a kind of in actuating system separate configurations, be exclusively used in the mechanical device of lock function, be called external lock; Another kind is at system actuator---and integrated in the pressurized strut, the mechanical device of a lock function is called internal lock.Above-mentioned mechanical internal lock integrated in pressurized strut mainly contains four kinds on steel ball lock, finger-type lock, collet chuck lock, retaining ring lock.
Steel ball lock (Cylinder lock with ball, steel ball lock), after the locking of steel ball lock, reliable for making steel ball working, locked groove and tapered piston should have enough hardness, prevent excessive wear or damage locked groove; For making each steel ball stressed more even, prevent the stressed excessive destruction of causing locked groove or steel ball of indivedual steel balls, higher to the manufacturing processing request of locked groove; The Cylinder lock with ball locking is reliable, simple in structure, but bearing capacity is less.
The steel ball lock is to utilize steel ball to stop piston rod to move right by the lock piston, realize the purpose that the lock piston bar moves right, the principle of this steel ball lock is to stretch out under hydraulic pressure when piston rod, steel ball on the piston (8～12) promotes tapered piston motion and Compress Spring when contacting with the lock piston; When piston moves on to the locked groove place with steel ball, steel ball is clamp-oned locked groove by tapered piston, and piston is pinned.When high pressure oil oppositely enters, promote the tapered piston motion, make tapered piston leave steel ball, piston just moves under the oil pressure effect, and unblanks with steel ball breaks away from locked groove.
It is large that finger-type is locked pressure, reliable and stable, makes, installation difficulty is large.
Collet chuck lock (petal lock, hinge lock), have two kinds in structural type, a kind of is that the hinge that the lock piston that moves about is arranged on the piston rod assembly is locked, and another kind is that the petal that the lock piston that moves about is arranged on the end-cap assembly is locked, its major advantage is that bearing capacity is larger, but the fast knot structure is longer;
Retaining ring lock is stressed large, and surface of contact is large, and is stressed steady, and after the retaining ring lock locking, bearing capacity is very strong.
It is steel ball lock and retaining ring lock that the pressurized strut of using at plane hydraulic system is used more.The retaining ring lock locking state is the harshest working state of retaining ring lock, and snap ring has to be received dividing of ring and a ring.Receive ring and refer to snap ring in the course of the work, only produce and shrink resiliently deformable, nature is its overall dimensions state; Zhang Huan refers to snap ring in the course of the work, only produces and opens resiliently deformable, and nature is its minimum dimension state.It is with the piston that moves about that prior art is opened the ring retaining ring lock, is arranged on the retaining ring lock on the piston rod assembly, and Zhang Huan is in snap ring is locked process, and the piston of locking need overcome the elastic force of snap ring, by force snap ring is opened.When locking, snap ring is in the pressure open configuration, when unblanking, withdraws from the piston of locking, and snap ring shrinks under the synergy of self elastic force, unlock pressure and load force, makes snap ring integral body enter annular lock endoporus, finishes the process of unblanking.
The working principle of retaining ring lock for when piston rod when hydraulic pressure moves down into extended position and culminates, snap ring just overlaps with locked groove on the housing, snap ring expands also in the card entry slot, piston is locked.The method of location is that the piston protuberance that moves about inserts in the snap ring internal diameter, prevents snap ring to shrink.This moment, piston rod just can not moved by external load function.When piston rod was regained, the piston that moves about was moved to the left under hydraulic pressure and snap ring is unclamped, and snap ring skids off from the locked groove inclined-plane under its elastic force and piston rod effect and unblanks.Although retaining ring lock has the very large advantage of its bearing capacity, but after snap ring unblanks to leave locked groove, snap ring the start cylinder bore can not be in open fully after free state, retaining ring lock in pressurized strut cylindrical shell movement process also with load, when particularly load is larger, under the effect of negative load, the pressurized strut cylindrical shell contacts with snap ring is heavily stressed, has the hidden danger that scratches the pressurized strut cylindrical shell.
The bearing capacity of above-mentioned said retaining ring lock is strong, and actual is incomplete.Because after mechanical lock and pressurized strut integrated, the bearing capacity of retaining ring lock can not only be considered locking ability, also should comprise the kinetic force of doing of the locking ability of mechanical lock and pressurized strut, it is large that retaining ring lock just locks load, and it is not strong to make kinetic force.
Summary of the invention
The present invention is that task provides that a kind of can to make band carry unlock pressure more approaching with unloaded unlock pressure, and locking ability and to make kinetic force stronger can bear large load, can avoid again the Novel clamp ring lock of cylindrical shell scuffing.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pressurized strut sliding block clamp ring lock, comprise: be assemblied in moving about in the pressurized strut axial end portion cylindrical shell and lock piston 10 and be arranged in the lockset annular die cavity, be installed in the slotted collar 4 on pressurized strut piston 2 end faces, it is characterized in that: the maximum free size that annular groove aperture 〉=slotted collar 4 that the assembling of pressurized strut lock end Step Shaft forms is opened fully, be fitted in the annular lock 3 on move about lock piston 10 and plunger end cap 12 assembled end, be shaped with the radially boss that cooperates with slotted collar 4 cylindrical trapezoid cross section boss tacit agreements on the port, and should be fitted on the pressurized strut step hole bottom end by the radially raised head face towards the center of circle; Floating slider 6 clampings of slotted collar 4 and radial support slotted collar 4 are between load lock collar 7 end faces and moving cylinder piston 2 end faces, at least three along the uniform T shape circular arc floating slider 6 of slotted collar 4 inner circle five equilibriums, by the bolt 9 that is fixed on pressurized strut piston 2 end faces, be flexibly connected by fastener hole and the radially elliptical aperture on the floating slider 6 that distributes on load lock collar 7 circumference, can in elliptical aperture, do radial motion.
On the free port of described floating slider 6, also be shaped with and the above-mentioned lock piston 10 multidiameter shaft nozzle cylindrical cones of moving about, the conical horn mouth that tapering is consistent.
The present invention has following beneficial effect than prior art:
The present invention arranges the transition floating slider 6 of a support openings snap ring moving about between lock piston 10 and the slotted collar 4, when slotted collar 4 is moved in the start cylindrical shell, the support floating slide block 6 that distributes and to make along the circumference equal dividing direction, support to slotted collar reaches maximum, because floating slider 6 grades divide direction to distribute, make floating slider stressed evenly, the load that can meet the demands, do not contact with the pressurized strut drum surface again, thereby avoid because of slotted collar and the excessive cylindrical shell scuffing phenomenon that occurs of cylindrical shell contact stress.
Because when slotted collar is locked in load, when particularly load is larger, at floating slider and piston end surface, fixedly under the effect of the frictional force of the frictional force, the floating slider that produce of the frictional force that produces of load lock collar, snap ring and floating slider and the piston that moves about generation, the unlock pressure of unlock pressure during much larger than zero load, the present invention is designed to the circular cone inclined-plane with floating slider 6 and the surface of contact of locking piston 10 that moves about, can dissolve floating slider and the frictional force that the piston that moves about produces, make band year unlock pressure and unloaded unlock pressure more approaching.When institute's bringing onto load is little when unblanking certainly, can make the cone inclined face.Wherein pressurized strut cylinder bore size is increased to the free size after opening fully greater than slotted collar, just can thoroughly eliminates the hidden danger that the open card ring lock scratches cylindrical shell.Pressurized strut cylinder bore size is to be determined by the size of ouput force, and pressurized strut cylinder bore size can not arbitrarily strengthen, and the circular cone bevel angle carries a size according to band and designs, and the circular cone bevel angle should be less than the Self-locking angle of machinery industry regulation.
The size that the present invention arranges at the slotted collar outer ring surface is less than the start cylinder bore, trapezoid cross section and the trapezoid cross section consistent with shape on the annular lock that the slotted collar free size can be opened fully, the receipts ring mode of operation that formed mutual tacit agreement cooperates, the reliability of locking is than the Zhang Huangao of prior art.Thereby efficiently solve the root problem that the conventional mechanical lock construction can't satisfy large load and scratch the pressurized strut cylindrical shell under large load-up condition.
The present invention compares result such as following table with the described mechanical lock of prior art:
