Description
Technical field
The invention belongs to technical field of mechanical transmission, more particularly to the ratchet mechanism that a kind of giant magnetostrictive material drives,
It is applied in the intermittently-driving of automation, and such as production line, wrist-watch second hand are walked about.
Background technology
Jiao Er found that magnetic its overall dimensions during being magnetized can change in 1840, later people
Referred to as magnetostrictive effect.Magnetostriction coefficient only has 40 × 10 to magnetostriction materials from the beginning-6Ni or Co crystal
Develop into magnetostriction coefficient up to 110 × 10-6Ferrite Material.The feature of magnetostriction materials causes that its development is very fast
Suddenly, especially the eighties U.S., Japan and other countries to try to be the first and done abundant research to its performance, phase structure and magnetic structure, and herein
On the basis of develop substantial amounts of practical devices.
On the other hand, the advantages of ratchet mechanism is with its simple structure, reliable operation, extensively should in all kinds of plant equipment
With being used for feeding, indexing or the occasion such as index, brake, surmounting, counting.The transmission of current ratchet mechanism be essentially all by
Motor is driven by slider-crank mechanism, and it is larger that generally existing volume, the shortcomings of complex structure.
In view of above-mentioned deficiency, the present inventor is by studying for a long period of time, it is proposed that a kind of displacement by giant magnetostrictive material
Amplify and keep the telecontrol equipment of function-driven ratchet mechanism, this case is produced therefrom.
The content of the invention
The technical problems to be solved by the invention be overcome it is existing by motor pass through slider-crank mechanism driving pawl
The complex structure of mechanism, the shortcomings of take up room big, and provide it is a kind of can be by the displacement equations of giant magnetostrictive material and holding
The telecontrol equipment of function-driven ratchet mechanism.
In order to solve the above technical problems, technical solution of the invention is：
The ratchet mechanism that a kind of giant magnetostrictive material drives, including drive system, displacement equations system, ratchet mechanism system
System and pedestal；The drive system includes the giant magnetostrictive material and coil that are fixed on pedestal；The ratchet mechanism system includes
Ratchet and the active ratchet and check pawl that coordinate with ratchet, the ratchet are connected on pedestal by bearing pin, check pawl hinge
It is connected on pedestal；The displacement equations system is arranged on the elongation end of giant magnetostrictive material and the active ratchet of ratchet mechanism system
Between, drive active ratchet displacement after being used to amplify the elongation of giant magnetostrictive material.
Described displacement equations system includes input lever, intermediate bar, take-off lever and back-moving spring, the input lever, intermediate bar
One end with take-off lever is hinged on pedestal；The elongation end of the giant magnetostrictive material connects with input lever near its hinged place
Touch, the free end of the input lever contacts with intermediate bar near its hinged place, free end and the take-off lever of the intermediate bar cut with scissors near it
Connect place's contact；Described active ratchet is hinged on the take-off lever, and described back-moving spring is arranged on the free end one of take-off lever
Side.
Described take-off lever is hinged on the bearing pin of the ratchet.
Described giant magnetostrictive material fixing end side is provided with to adjust the initial elongation of the giant magnetostrictive material
The pretension bolt of amount.
After such scheme, the present invention realizes the telescopic effect of giant magnetostrictive material, displacement equations system by magnetic field
Unite for the amplification for realizing telescopic displacement, single hook tooth can be promoted to move, while compression reseting spring, when without magnetic field
During effect, giant magnetostrictive material recovers the original length, under action of reset spring, ratchet mechanism active ratchet pawl reset.Such as
This realizes self-action intermittently-driving repeatedly.Because the present invention is creatively using the flex effect of giant magnetostrictive material, and lead to
The operating of displacement equations system drive ratchet mechanism is crossed, so as to realize the self-action intermittent drive of ratchet mechanism, its simple structure
And occupy little space.

Fig. 2 is the installation diagram of drive system of the present invention and displacement equations system；
Fig. 3 is ratchet mechanism system forward travel figure of the present invention.
Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
It is this as shown in Figure 1 to Figure 3 disclosed is the ratchet mechanism that a kind of giant magnetostrictive material drives
The preferred embodiment of invention.Described ratchet mechanism mainly includes drive system 1, displacement equations system 2, ratchet mechanism system 3
With pedestal 4.Wherein：
Described drive system 1 mainly includes giant magnetostrictive material 11 and coil 12, and the giant magnetostrictive material 11
It is each attached on pedestal 4 with coil 12.Further, the described fixing end side of giant magnetostrictive material 11 is provided with pretension bolt
13, it is used to adjust the initial elongation amount of the giant magnetostrictive material 11.
Active ratchet 32 and non-return spine that described ratchet mechanism system 3 mainly coordinates including ratchet 31 and with the ratchet 31
Pawl 33, the ratchet 31 is connected on pedestal 4 by bearing pin 34, and the check pawl 33 is hinged on pedestal 4.
Described displacement equations system 2 is arranged on the elongation end of giant magnetostrictive material 11 and the master of ratchet mechanism system 3
Between pawl 32, the displacement of active ratchet 32 is driven after being used to amplify the elongation of giant magnetostrictive material 11.The displacement is put
Big system 2 can use multiple structural forms, and in the present embodiment, described displacement equations system 2 uses three-level structure for amplifying.Tool
Body is that the displacement equations system 2 mainly includes input lever 21, intermediate bar 22, take-off lever 23 and back-moving spring 24, the input lever
21st, intermediate bar 22 is hinged on pedestal 4 with one end of take-off lever 23.The elongation end of the giant magnetostrictive material 11 and input
Bar 21 is contacted near its hinged place, and the other end of the input lever 21 is that free end contacts with intermediate bar 22 near its hinged place, should
The other end of intermediate bar 22 is that free end contacts with take-off lever 23 near its hinged place.It is defeated that described active ratchet 32 is hinged on this
On rod 23, described back-moving spring 24 is arranged on the other end i.e. free end side of take-off lever 23.Further, for simplification
Mechanism, described take-off lever 23 can be hinged on the bearing pin 34 of the ratchet 31.
In forward travel, its size in the presence of external magnetic field of giant magnetostrictive material 11 extends mechanism, by position
After moving the preceding two-stage displacement equations of amplification system 2, intermediate bar 22 acts on the bottom of take-off lever 23, real with bearing pin 34 as fulcrum
The third level of existing displacement is amplified.Take-off lever 23 drives active ratchet 32 to swing forward, and driving pawl 31 is rotated counterclockwise, non-return spine
Pawl 33 is used to prevent ratchet from inverting.
In reseting movement, giant magnetostrictive material 11 recovers original size under without magnetic field, and back-moving spring 24 is in elasticity
Power effect is lower to drive take-off lever 23 to swing backward, and intermediate bar 22 and input lever 21 return to original position in the presence of take-off lever 23, are
Forward travel next time is prepared.
The above, only presently preferred embodiments of the present invention, not for limiting the scope of present invention implementation.Therefore but
Change or modification that all claims under this invention and specification are done, should all belong to scope that patent of the present invention covers it
It is interior.
