Automatic unloading device of drop test machine

Abstract

An automatic unloading device of a drop test machine belongs to the technical field of drop impact test, and aims to solve the problems in the prior art, three groups of spring accumulators are equidistantly arranged on a top plate, the lower part of the top plate is connected with a support frame, two sides in the support frame are respectively provided with a slide rail, and a slide block on the slide rail is connected with a box body; the lower portions of the three spring force accumulators make contact with the top of the box body, the two buffers are installed at the bottom ends of the two sides in the supporting frame respectively, and a tested object bracket is installed on the overturning plate and connected through a hinge; the box body and the overturning plate are connected through two rotating shafts; a posture fixing frame is mounted in front of the top plate; the top plate and the box body are locked through a lock pin mechanism; one end of the pull rod is fixed on the turnover plate, and the other end is connected with the connecting rod through a rotating shaft; the connecting rod is connected with the top plate through a shaft; and the limiting nut is fixed below the top plate and located above the box body to limit the rising position of the box body along the sliding rail, and after the limiting position is reached, the lock pin mechanism is locked through a plug pin. The tested object can freely fall without posture change.

Description

technical field [0001] The invention belongs to the technical field of drop impact testing, in particular to an automatic unloading device for a drop testing machine. Background technique [0002] Many products need to be subjected to a drop test after they leave the factory, that is, to raise the tested product to a certain height and release it, let it do a free fall, and hit it on a steel plate or cement board with a certain hardness. According to the drop test results, the impact resistance of the product sex is evaluated. The drop test machine is mainly used for the drop test of the tested product. The tested product is installed on the drop test machine. The drop test machine automatically controls the unloading device to carry the tested product to a preset height, and releases the tested product through the unloading device. , causing it to hit the ground in free fall. [0003] The unloading device of the existing drop test machine mainly uses an L-shaped reversibl...
