41 shaft extends along the short transverse of body；The shaft of motor 41 is fixedly connected with adjustment seat 45, eccentric wheel 42 and motor 41
Shaft synchronous couple and be articulated on adjusting block 46 by eccentric shaft；The axis of eccentric shaft and the shaft axis of motor 41 are eccentric
Setting；The connection synchronous with eccentric wheel 42 of one end of first connecting rod 43；The other end of first connecting rod 43 is articulated in the one of mounting plate 20
End；The other end of mounting plate 20 is articulated on body.
On the basis of the said structure, using the adjustable eccentric wheel apparatus for optical anti-vibration test of the utility model
When, by taking test piece is camera module as an example, camera module to be detected can be mounted on mounting plate by workpiece jig
On 20, rotated thereafter through motor 41 with movable eccentric wheel 42, the rotation of eccentric wheel 42 drives first connecting rod 43 to rotate, and first connecting rod
43 rotation can be mounted plate 20 and limit the reciprocally swinging for being converted into and driving mounting plate 20, be mounted on mounting plate 20 to drive
Camera module shake, camera module shoots external image in dither process, to simulate hand tremor to taking the photograph
As the progress imaging effect stabilization test of head mould group, testing efficiency is higher.
It should be noted that the shaft of motor 41 is fixedly connected with adjustment seat 45, and eccentric wheel 42 is pivotally connected by eccentric shaft
In on adjusting block 46；Adjusting block 46 is slidably matched with adjustment seat 45, in this way, can be by keeping adjusting block 46 sliding in adjustment seat 45
