Drop-hammer impact testing machine

Abstract

The invention discloses a drop-hammer impact testing machine. The drop-hammer impact testing machine comprises a mechanical part and an electronic control part, wherein the mechanical part comprises adrop-hammer lifting mechanism, a drop-hammer executing mechanism, an impact protection mechanism, a side feeding mechanism and the like, the electronic control part adopts a combination mode of an upper computer and a lower computer, wherein the upper computer adopts an industrial control computer and a display. According to the drop-hammer impact testing machine, the drop-hammer lifting mechanism is driven by adopting a servo motor, and the grabbing, lifting and releasing processes of the drop-hammer executing mechanism are realized by controlling the power gain and loss of an electromagnet;a closed-loop control mode is adopted between the servo motor and a laser ranging sensor, so that the lifting height and the releasing height of the drop-hammer executing mechanism can be accuratelycontrolled; the system impact energy and the impact speed can be achieved by controlling an impact hammer body to be released from different heights. According to the drop-hammer impact testing machine provided by the invention, the side feeding mechanism with double-sided feeding is used, so that the testing capacity of testing equipment is improved, the labor intensity of workers is lowered, andthe cost of rebuilding the testing equipment is lowered.

Description

technical field [0001] The invention relates to the technical field of automobile instrument panel testing equipment, in particular to a drop weight impact testing machine used in the airbag area of ​​the automobile instrument panel. Background technique [0002] During the production process of automobile dashboard, it needs to be subjected to drop weight impact test to verify product quality. During the test, the existing testing machine installs the product directly in front of it, and feeds the product along the card slot, so that the area of ​​the instrument panel airbag is exposed directly under the hammer head, and the centerline of the hammer head and the area of ​​the instrument panel airbag are weakened Lines coincide. However, this kind of testing machine can only be applied to the test of the corresponding specific type of automobile dashboard; it cannot adapt to the change of the structure of the airbag frame of the automobile dashboard; there are complex opera...
