Explanation, the content that embodiment is mentioned is not to restriction of the present utility model.Below in conjunction with accompanying drawing, this utility model is carried out
Detailed description.
A kind of rocker arm body that this utility model provides, including frame main body the 1, first rocking arm 2 and the second rocking arm 3, described
The first cam 6 driving the first rocking arm 2 to swing and the second cam 7 driving the second rocking arm 3 to swing it is provided with in frame main body 1；
In this utility model, described frame main body 1 is provided with and drives the first cam 6 and the driving motor 8 of the second cam 7 operating, institute
State the first cam 6 and described second cam 7 is connected to drive on the main shaft 9 of motor 8, the protruding end of described first cam 6 and the
The protruding end dislocation of two cams 7.When described driving motor 8 rotates, owing to described first cam 6 and described second cam 7 all connect
It is connected to drive on the main shaft 9 of motor 8, drives the first cam 6 and the second cam 7 to move simultaneously, convex due to described first cam 6
The protruding end dislocation of origin or beginning and the second cam 7, drives the main shaft 9 of motor 8 when rotating, and the protruding end of described second cam 7 is first
Row conflict the second rocking arm 3, drives the second rocking arm 3 to swing, and drives motor 8 to be rotated further, and the protruding end of the second cam 7 continues motion
And when departing from the second rocking arm 3, the protruding end of the first cam 6 is conflicted the first rocking arm 2, drives the first rocking arm 2 to swing, and described first shakes
Arm 2 and the second rocking arm 3 do reciprocal arc track oscillating motion, described first rocking arm 2 and the second rocking arm 3 self-movement respectively, divide
Open control, the reliability and stability of mechanism kinematic are effectively ensured, be also convenient for maintainer inspection, convenient maintenance simultaneously.
In this utility model, described first rocking arm 2 is provided above upper slide 10, and described upper slide 10 is fixedly connected on
On one rocking arm 2.In this utility model, described frame main body 1 is fixedly connected with for limiting the amplitude of fluctuation that the first rocking arm 2 swings
The front pressuring plate 4 of degree maximum point, described frame main body 1 is also fixedly connected with for keeping described upper slide two ends stress balance
Rear fender 5.Described first rocking arm 2 does circular motion track, during the circular motion of described first rocking arm 2, in order to prevent
During one rocking arm 2 does circular motion, amplitude of fluctuation is excessive, causes mechanical failure or flogs a dead horse, so before frame is provided with
Pressing plate 4, described front pressuring plate 4 limits the amplitude of fluctuation maximum point that the first rocking arm 2 swings, and the i.e. first rocking arm 2 is doing arc track pendulum
Time dynamic, when the first rocking arm 2 swings outward, when front pressuring plate 4 withstands upper slide 10, the first rocking arm 2 swings to amplitude of fluctuation
A little louder；Described rear fender 5 define first rocking arm 2 swing before initial point, i.e. the two ends stress balance point of upper slide 10, first
The hunting range of rocking arm 2 is limited by front pressuring plate 4 and rear fender 5, can be avoided rocking arm amplitude of fluctuation excessive and do too much
Idle work, it is also possible to reduce the probability of mechanical failure.Described upper slide 10 is fixedly connected on the first rocking arm 2, so first
Rocking arm 2 is when resting state, and the most described upper slide 10 is in level, the upper surface of described upper slide 10 respectively with front pressuring plate
The lower surface of 4 and the lower surface of rear fender 5 are inconsistent, keep the two ends stress balance of upper slide 10；Projection when the first cam
End jack-up the first rocking arm 2, the first rocking arm 2 does arc track and swings, and when the first rocking arm 2 swings, upper slide 10 departs from front pressuring plate 4 He
Rear fender 5, the i.e. first rocking arm 2 is when swinging, and upper slide 10 does not produce friction with front pressuring plate 4 and rear fender 5, and the first rocking arm 2 is put
After Dong, when upper slide 10 conflict front pressuring plate 4 again, front pressuring plate 4 withstands upper slide 10, and the first rocking arm 2 swings to amplitude of fluctuation
Maximum point, produces static friction between front pressuring plate 4 and upper slide 10, the first rocking arm 2 swings static, compared in prior art, existing
The amplitude of fluctuation of some rocking arms is excessive, and the amplitude of fluctuation that front pressuring plate 4 is possible to prevent rocking arm is excessive, greatly reduces between machinery
Friction, increases mechanical life.
