Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described.Obviously, described accompanying drawing is part of the embodiment of the present utility model, rather than entirely
Portion's embodiment, those skilled in the art on the premise of not paying creative work, can also obtain it according to these accompanying drawings
His design and accompanying drawing.
Fig. 1 is mechanics schematic diagram of the present utility model.
Embodiment
Design, concrete structure and caused technique effect of the present utility model are carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is part of the embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belong to the model of the utility model protection
Enclose.In addition, all connection/annexations being previously mentioned in text, not singly refer to component and directly connect, and refer to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more excellent draw bail.Each technology in the invention is special
Sign, can be with combination of interactions on the premise of not conflicting conflict.
Reference picture 1, a kind of submissive adjustable constance force system, including strong output device 1, constant force device 2, the power output dress
1 is put to be connected with constant force device 2, the power output device 1 includes governor motion 11, the constant force device 2 include roller 21,
Cam 22, connecting rod 23 and submissive deformation mechanism 24, the submissive deformation mechanism 24 include elastic component, the roller 21 with it is convex
Wheel 22 is fixed together, and the cam 22 is connected with one end of connecting rod 23, such as is connected by steel wire rope, and the connecting rod 23 is in addition
One end is connected with submissive deformation mechanism 24, and the roller 21 is connected with power output device 1, such as is attached by steel wire rope,
The external diameter change of the cam 22 is adapted with the deformation of the elastic component of submissive deformation mechanism 24.
When acting on a power F to the left on power output device 1, roller is pulled to rotate counterclockwise by steel wire rope, by
Together with cam is stationarily connected to roller, so cam can also rotate counterclockwise, and then steel wire rope is driven to haul
Connecting rod also rotates counterclockwise, then connecting rod will drive submissive deformation mechanism to be subjected to displacement, and then causes elastic component that shape occurs
Becoming, bigger power can be produced by producing bigger flexural deformation in theory, but because the contour curve on cam is according to elastic structure
The change of part and design, i.e., when act on the power on cam contact point become it is big when, the distance of contact point to cam center of rotation
It will reduce, so as to which torque of the guarantee effect on cam is constant all the time, because the diameter of roller is constant, so according to public affairs
Formula (A), that is, the power acted on a steel cord can also keep constant, so that the power on capable output device 1 remains constant,
To reach the effect of constance force output.
FCamrCam=FRollerRRoller (A)
(wherein F cams are the tangential force at any point on cam profile curve, and r cams are during corresponding points rotate to cam
The distance of the heart, F rollers are the tangential force on roller edge, and R rollers are the radius of roller.)
Conversely, when if power F is less than setting value, being delivered to the power of submissive deformation mechanism 24 will diminish, then elastic component
Deflection can also be reduced accordingly, so that submissive deformation mechanism 24 is moved to the left, then connecting rod can be also moved to the left, Ran Houhui
Band moving cam and roller also rotate clockwise, and are then moved right again by steel wire rope motive force output device, make power F thereon
It can just stop when being changed into setting value.
Sum it up, power output device can keep constance force to export in set moving range all the time.For example, by the machine
Structure apply to control bistrique carry out polishing processing when, when polish contact force increase when, mechanism will retreat with rotary bistrique, Zhi Daojie
Touch is reduced to setting value, and mechanism just stops movement；When contact force of polishing reduces, mechanism chance promotes bistrique to feed forward,
Until contact force increases to setting value, mechanism just stops movement.
Preferred embodiment is further used as, the governor motion 11 includes lever, elevating lever, sliding block and output
Bar, the front end of the lever is be hinged with constant force device 2, and the elevating lever is hinged with sliding block, and the sliding block slides in lever, institute
The rear end for stating take-off lever and lever is hinged.From the above, it may be appreciated that the power of power output device output is a constant constance force, thick stick is utilized
Rod principle, by adjusting elevating lever so that the position of sliding block changes, so that the power of output is realized by lever principle
Zoom in or out.
It is further used as preferred embodiment, the submissive deformation mechanism 24 includes support base, in the support base
Provided with guide pillar, more pieces of resilient component is provided between the guide pillar and support base, the guide pillar is connected with connecting rod 23.Connecting rod movement
When drive guide pillar to do planar movement,, can be with dynamic elasticity structure so when guide pillar move and because support base is relatively fixed
Part deforms upon, and so as to act power, goes the change of counteracting force.
Preferred embodiment is further used as, the connecting rod 23 includes pin joint, and the end of the connecting rod 23 is with leading
Post is hinged by swing rod.Certainly, connecting rod can be directly connected to guide pillar, but be hinged by way of swing rod, Ke Yijie
Save space so that structure is compacter.
Better embodiment of the present utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make a variety of equivalent changes on the premise of without prejudice to the utility model spirit
Type or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
