The damping device of the utility model on high accuracy swinging screen, the material of above-mentioned buffer stopper be elastic material.
The damping device of the utility model on high accuracy swinging screen, the material of described buffer stopper be rubber.
The damping device of the utility model on high accuracy swinging screen, the draw-in groove on described buffer stopper is arranged to " V " shape structure.
Compared with prior art, the beneficial effects of the utility model are:
The utility model, by the setting of oscillating bearing, makes screen box to swing easily, greatly reduces its wearing and tearing, meanwhile, by the setting of damping device, reduce further it and impacts the vibrations produced, extend its service life greatly; In addition, by arranging kidney ellipsoid hole on base plate, can regulate swing arm easily, thus can intervene rocking tendency and regulate, be conducive to improving its precision.
