Abstract
The invention discloses an adjustable work bench type force loading apparatus and a calibration method thereof. The apparatus comprises a support table, a step workbench frame, screw rods, support upright columns, an adjustable workbench mechanism, a horizontal loading mechanism, a vertical loading mechanism, a synchronous belt, a vertical slide frame, a worm gear worm mechanism, a rocking bar, elevating nuts and a dividing ruler. Since the adjustable workbench mechanism is employed, a loading work plate can realize movement in a vertical direction and a horizontal direction, and convenience is provided for calibrating calibrated members with complex profiles or different dimensions. Since the vertical loading mechanism can only move vertically, the horizontal loading mechanism is fixed and still, the complexity of the loading mechanisms, caused by too many movement directions is reduced, and the strength of the loading mechanisms in loading a wide-range load is improved; and through the different fixation modes of an L-shaped calibration plate on the loading work plate, the area utilization rate of the loading work plate is greatly improved, and independent loading and compound loading are realized.
