Specific embodiment
Below in conjunction with attached drawing of the invention, clear, complete description is carried out to the technical solution of the embodiment of the present invention.
In conjunction with shown in FIG. 1 to FIG. 4, the embodiment of the present invention is revealed a kind of for controlling swing angle on thrombus elastometer
With the device of speed, including cam 10, rocker arm 20 and return unit 30, rocker arm 20 begins under the action of return unit 30 with cam 10
Last phase contact, and rocker arm 20 drives the controlled body (not shown) synchronous hunting being disposed thereon while cam 10 rotates, from
And the curve characteristic of cam 10 is utilized to realize the accurate rocking tendency and swing speed for controlling controlled body.
Specifically, cam 10 is connected with a power source (not shown), in being rotated by for power source.The present embodiment
In, the drive shaft of power source is connected with the fixed part (such as fixation hole 11) of cam 10, and when implementation, motor etc. is can be used in power source,
It can certainly be realized using manpower, as long as the power of the rotation of cam 10 can be given.
Preferably, described device further includes the position sensor (not shown) for incuding 10 turned position of cam.Implement
When, photoelectric sensor can be used in position sensor or other are able to detect the position sensor of 10 position of cam.
It should be noted that the different angle and speed that are needed to wave according to controlled body, can select the convex of respective shapes
Wheel 10 realizes that cam face that is, here is not limited to one kind, can be selected according to swing angle, not limited here to replace
It is fixed.
One end of rocker arm 20 fits with the lateral surface of cam 10 and contacts, in the present embodiment, the central axis of rocker arm 20 with it is convex
The fixation hole 11 of wheel is on the same line.Preferably, in order to reduce the friction between cam 10 and rocker arm 20, the present embodiment is being shaken
A bearing 40 is installed on this one end that the lateral surface of arm 20 and cam 10 fits, the bearing 40 and the lateral surface of cam 10 are affixed
Splice grafting touching, that is to say, that be in contact by the bearing 40 with rocker arm 20.
It should be noted that cam 10 is driving 20 side rocking of rocker arm in the present embodiment, such as it is swung left and right, rather than
(or front and back) telescopic moving up and down, so, in addition to the position coaxial with rocker arm 20 is bonded, other bonding position are all suitable for cam 10
In the present embodiment.
The other end of rocker arm 20 waves fulcrum 50 with one and is connected, and rocker arm 20 waves fulcrum 50 along this with the rotation of cam 10 and shakes
It puts, in the present embodiment, this waves the central axis of fulcrum 50 Yu rocker arm.
The lower section of the other end of rocker arm 20 is fixedly connected with controlled body, and cam 10 controls shaking for the controlled body by rocker arm 20
Pendulum.The fixed form of controlled body and rocker arm 20 can there are many, such as can be screw and be fixedly connected, be also possible to interference fit and connect
It connects.
Return unit 30 is connected with rocker arm 20, and one end of rocker arm 20 connects with cam 10 always under the action of return unit 30
Touching.In the present embodiment, 30 one end of return unit is connected with 20 side of rocker arm (close to the side of cam 10), and the other end and one is fixed
Point 60 is fixed, gives rocker arm 20 lateral force close to cam 10 when rocker arm 20 waves so that 20 one end of rocker arm always with it is convex
Wheel 10 fits.When implementation, spring is can be used in return unit 30.
The working principle of the invention is: for cam 10 by motor driven rotation, rotation while, drives rocker arm 20 or so to put
It is dynamic, it drives controlled body accordingly to be rotated while rocker arm 20 is swung, controlled body is accurately controlled by the curve characteristic of cam 10
Swing angle and swing speed.
Technology contents and technical characteristic of the invention have revealed that as above, however those skilled in the art still may base
Make various replacements and modification without departing substantially from spirit of that invention, therefore, the scope of the present invention in teachings of the present invention and announcement
It should be not limited to the revealed content of embodiment, and should include various without departing substantially from replacement and modification of the invention, and be this patent Shen
