Drop test machine and method for adjusting drop attitude

Abstract

A drop testing machine and a method for adjusting a drop angle belong to the technical field of drop tests, aiming to solve the problems in the prior art that it is troublesome to adjust the posture of a test object, the angle control cannot be realized, and the drop test effect is poor. The drop testing machine of the present invention includes: a drop frame, which performs a rotary motion relative to its own rotating shaft; a lifting mechanism arranged on one side of the drop frame along the vertical direction; and a manipulator fixedly connected by a crank arm and the lifting mechanism. plate, an attitude adjustment unit connected between one end surface of the fixed plate and the crank arm, and two sets of grasping units symmetrically arranged on the other end surface of the fixed plate; the attitude adjustment unit drives the manipulator as a whole to realize horizontal and vertical rotations, The relative opening and closing movement of the two grasping units realizes the flexible grasping or releasing of the sample. The invention can realize the adjustment of arbitrary drop height and drop posture, realize the flexible grasping of the test object, and prevent the test object from being damaged or falling off due to the magnitude of the clamping force.

Description

technical field [0001] The invention belongs to the technical field of drop testing, and in particular relates to a drop testing machine and a method for adjusting drop posture. Background technique [0002] The drop test machine is specially used to test the damage of product packaging by falling, and to evaluate the impact resistance strength during transportation and handling. It adopts double-column or double-rail guidance, and the height and number of drops can be set. It works stably and reliably. It can realize edge, surface, Corner drop, the machine adopts photoelectric control, and the drop height can also be freely selected. The drop release adopts electric control and pneumatic control, which can make the sample drop freely instantly, and perform drop impact test on the edges, corners and planes of the packaging container. Drop test machine classification: single-arm drop test machine, double-arm drop test machine; the drop test machine simulates the situation of ...
