Embodiment
For that can further appreciate that the feature of the utility model, technological means and the specific purposes reached, function, below
The utility model is described in further detail with embodiment with reference to attached drawing.
As shown in attached drawing 1-4, a kind of high-speed plane vibrating mechanism, including fixed frame 13,13 upper end of the fixed frame installing
There is motor 1,13 bottom surface of fixed frame is equiped with fixed plate 10, and fixed plate 10 is equipped with main eccentric shaft 9 and secondary eccentric shaft 4, main bias
By the axis connection of connector 2 and motor 1, main eccentric shaft 9 and secondary eccentric shaft 4 pass through angular contact ball bearing 8 respectively for the upper end of axis 9
With fixed plate attaching, i.e., main eccentric shaft is installed by an angular contact ball bearing and fixed plate, and secondary eccentric shaft passes through another angle
Contact ball bearing is installed with fixed plate so that is provided with two angular contact ball bearings in fixed plate altogether, the main eccentric shaft 9 and pair are inclined
4 lower end of mandrel is passed down through after fixed plate 10 passes through angle respectively with 12 attaching of shaking platform, the main eccentric shaft 9 and secondary eccentric shaft 4
Contact ball bearing 11 and 12 attaching of shaking platform, i.e., be provided with two angular contact ball bearings, a corresponding master altogether on shaking platform
The equal length of eccentric shaft and another then corresponding secondary eccentric shaft, main eccentric shaft and secondary eccentric shaft, the i.e. main eccentric shaft and pair are inclined
The structure of mandrel, size dimension are identical.Motor is preferably servomotor, or other kinds of electric rotating machine.Eccentric shaft
Eccentric position be located at the lower end of the eccentric shaft, the rotary inertia under the conditions of running at high speed can be reduced as far as possible, so as to subtract
Small vibration, increase load.Motor drives main eccentric shaft turns, and main eccentric shaft can be at a high speed under the action of angular contact ball bearing
Smoothly rotated under state, the bias of main eccentric shaft causes shaking platform to be subjected to displacement, and displacement is delivered to pair by shaking platform again
On eccentric shaft, secondary eccentric shaft is also produced rotary motion, pass through the limitation of main eccentric shaft and secondary eccentric shaft so that shaking platform is only
Translational vibration can be done, and the eccentricity that the Oscillation Amplitude of the shaking platform is main eccentric shaft.
In addition, being set with synchronizing wheel 6 on main eccentric shaft 9 and secondary eccentric shaft 4, the synchronizing wheel on main eccentric shaft 9 passes through same
Step band 7 is connected with the synchronizing wheel on secondary eccentric shaft.By the synchronizing wheel, further ensure that main eccentric shaft and secondary eccentric shaft keep same
The rotation of step.
Further, support plate 3 is also equipped with main eccentric shaft 9 and secondary eccentric shaft 4, which is located at the upper of synchronous belt 7
Side, main eccentric shaft 9 and secondary eccentric shaft 4 are connected by spring bearing 5 and the installation of support plate 3 respectively.Pass through the support plate, Neng Goufang
The generation only concentrated in main eccentric shaft and secondary eccentric shaft upper stress, reduces equipment noise, makes the smooth even running of mechanism.
In addition, two angular contact ball axis on the distance between two angular contact ball bearings in fixed plate, shaking platform
The distance between hold and support plate on the distance between two spring bearings it is equal, ensure the stability and reliability of movement.
The connector is shaft coupling, belt gear or chain drive, it is only necessary to which motor can be smoothly
Main eccentric shaft turns are driven, the known technology means of this transmission mechanism generally use those skilled in the art.
In the utility model, main eccentric shaft, secondary eccentric shaft, shaking platform and fixed plate substantially constitute four bars simultaneously
Online structure, as shown in Figure 5, wherein connecting rod AB equivalent to secondary eccentric shaft, connecting rod CD equivalent to main eccentric shaft, connecting rod BC equivalent to
Shaking platform, connecting rod AD is equivalent to fixed plate.Motor drives main eccentric shaft turns, and bias can be produced in main eccentric shaft rotary course
Displacement.Equivalent to a continuous moment of torsion is applied at revolute pair D, drive connecting rod BC steady, and then drive connecting rod AB around revolute pair A
Rotate, limited be subject to connecting rod AB and connecting rod CD so that BC bars are zero in the Normal Displacement of its plane of motion, i.e. shaking platform
Translational vibration can be produced.
When the θ angles between connecting rod AB and connecting rod AD are 0 ° or 180 °, for the dead point of the motion.Main eccentric shaft exists
In rotation process, due to being eccentric structure, center displacement can be then produced relative to original axial location, and then form folder
Angle.When θ angles are 0 °, the angle between connecting rod AB and connecting rod AD is also 0 °, if actuating mechanism revolves main eccentric shaft at this moment
Turn, connecting rod CD rotates clockwise about revolute pair D, and there will be rotate clockwise and rotate counterclockwise around revolute pair A by connecting rod AB
Existing possibility.If rotation direction is identical, structure smoothly operates, if rotation direction is on the contrary, structure is stuck.Equally, no
Drive manner by connecting rod CD is that clockwise or counterclockwise, θ angles are 0 ° or 180 °, and all there may be the stuck possibility of structure
Property.In addition, connecting rod CD is in the case where driving connecting rod BC and then drives connecting rod AB to rotate, but due to the four bars parallel institution
Closed loop characteristic and actual processing and the error of assembling so that connecting rod AB and connecting rod CD are there are certain differential seat angle, so as to also may be used
Stuck phenomenon can be produced.It occurs in order to prevent, on main eccentric shaft and secondary eccentric shaft, adds synchronizing wheel 6 and synchronous belt 7
Transmission mechanism, can ensure connecting rod AB and connecting rod CD（I.e. main eccentric shaft and secondary eccentric shaft）The angle with connecting rod AD is any respectively
Moment is all identical, it is ensured that the stability and reliability of operation.
It should be noted that these are only the preferred embodiment of the utility model, it is new to be not limited to this practicality
Type, although the utility model is described in detail with reference to embodiment, for those skilled in the art, it is still
It can modify to the technical solution described in previous embodiment, or equivalent substitution is carried out to which part technical characteristic,
But where within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on, should be included in
Within the scope of protection of the utility model.
