Embodiment
With reference to Figure of description, the invention will be further described：
The plug and play type pressure of the present invention turns round shaft coupling by torsion axle module（Driven member）With wedge module（Driving link）
Composition.
Reversing axle module includes a torsional axis 10, central shafts 12, the 3rd roller 9, the 4th roller, the 3rd spring bases
13rd, the 4th spring base 15, the jump ring 16 of inner spring 14 and second, together with central shaft 12 connects firmly with the tight fit of torsional axis 10, into ten
Shape, the 3rd roller 9 and the 4th roller are fixed on the both ends of central shaft 12 with jump ring respectively, when torsional axis moves axially, the 3rd rolling
The rolling of the roller of wheel 9 and the 4th greatly reduces axial friction, while during torsional axis torsion, central shaft plays leverage,
Torsional friction is reduced, the 3rd spring base 13, the 4th spring base 15, inner spring 14 are fixed on the right end of torsional axis by jump ring 16
Portion, the 3rd spring base 13 and the 4th spring base 15 are limited in the cavity of wedge 11, after wedge stress, pass through inner spring 14
Indirect power transmission to torsional axis, as shown in fig. 7,。
Wedge module section includes the first roller 1, the second roller 6, the first spring base 3, outer spring 4, second spring seat 5
Formed with jump ring etc..Wedge 11 is integrated part, for simplify process, can will upper and lower two vertical pivots 7 in addition process after with wedge
Tight fit connects firmly together；First roller 1, the second roller 6 are support guiding parts when wedge is moved axially and rotated, because
This, its diameter is big compared with the roller on central shaft；Wedge is hollow structure, and torsional axis right-hand member is stretched into inside wedge, and is passed through
3rd jump ring 18 is flexibly connected together, as shown in Figure 7；Wedge left end opens up two cylindrical stopper slots 19, is the 3rd roller
9th, the roll channel of the 4th roller；First spring base 3, second spring seat 5, outer spring 4 are sleeved on wedge right-hand member, are consolidated by jump ring
Fixed, outer spring is in micro- compressive state；Wedge moves left and right under external force, limit of the outer spring in end cap 2 and way block 8
System is lower to be pressurized, and spring force makes wedge be resetted after straight line-twist motion conversion is completed.
Wedge component internal can easily be fitted into by the 3rd jump ring by reversing the head of axle module, need to borrow during assembling
Help jump ring mounting hole 17 to operate the second jump ring and the 3rd jump ring, reverse axle module and be not directly contacted with wedge module,
But pass through the inner spring Elastic Contact on torsional axis；External force input is applied on wedge component, drives wedge axially to move
It is dynamic, so as to compress outer spring, untill external force and spring force balance each other；While wedge moves axially, in its first rolling
Rotated under the limitation of wheel and the second roller, after external force is removed, wedge resets in the presence of outer spring force, for next time
Rotary motion prepare；Anglec of rotation size depends on the displacement of wedge upper roller（That is the inclination angle of guide groove 20
Degree and length）, wedge rotation drive torsional axis rotation, by torsional axis output torque, the axial movement of torsional axis can influence
The exact numerical of output torque, but in practical application, the torsional axis strong point has the presence of frictional force, overcome torsional friction than
Axial movement friction is much easier, therefore output torque is directly proportional to axial displacement, and then proportional to input external force.
Wedge module is to realize the structure of straight line and twist motion conversion, and outer spring is in minute-pressure state, avoids its line
Property poor link, when external force promotes wedge axial movement, limited site on end cap, the first spring base of control does not follow wedge shape
Part moves axially, so that outer spring is pressurized, when external force is removed, wedge restores under spring force, plays reset
Effect.
It is output twist motion to reverse axle module（Moment of torsion）Structure, its contact position with wedge has four, first,
Two symmetrical stopper slots coordinate and roll points on the roller of axle both ends the 3rd and the 4th roller, with wedge centered on two contact positions, the 3rd,
Four positions are the torsion spring base of shaft head the 3rd and the 3rd jump ring and spacing, the 3rd spring base and the 3rd card of wedge internal holes
Spring and the cooperation inside wedge, limit the axial location of torsional axis, it is kept flexible contact with wedge, but do not increase
Frictional force between the two.
Wedge module and torsion axle module can be fit directly into together, realized and coupled by the 3rd jump ring, plug and play,
It is simple and convenient.
First roller, the second roller, the 3rd roller and the 4th roller are spherical roller so that the contact in motion conversion
Position is a shape, is substantially reduced because stagnant ring influences caused by frictional force；Roller and roller groove in real work（That is stopper slot
19 and guide groove 20）Between must leave certain interval（20 μ or so）, the error caused by the gap can pass through Chatter Compensation skill
Art eliminates.
The implementation principle of this example is：As shown in fig. 7, wedge right-hand member can pass through pin with the push rod of proportion electro-magnet
Connection, electromagnet provide the push-pull effort of axial movement（Bidirectional electromagnet）, thrust is directly passed to wedge, and wedge axially moves
Dynamic, two rollers in the presence of the guide groove of way block, while driving wedge moves axially, also revolve wedge up and down
Transhipment is dynamic, and wedge by with the lever force that two roller contact points are formed on torsional axis, wedge rotation is formed
Twisting resistance passes to torsional axis, therefore the twist motion for torsional axis is finally transmitted in the horizontal movement of wedge, and two components are matched somebody with somebody
Close and complete to be axially moved the conversion with twist motion；Interior outer spring is completed to reset and coupled under the cooperation of jump ring and limit point
Effect, form the complete function that pressure turns round shaft coupling.
Above-mentioned embodiment is used for explaining the present invention, rather than limits the invention, in the spirit of the present invention
In scope of the claims, to any modifications and changes of the invention made, protection scope of the present invention is both fallen within.
