Specifically, the key impact testing device further comprises a detection device which is connected with the tested key and used for detecting whether the key is invalid or not. After each impact test of the key, it is necessary to detect whether the key has failed and to record the height and quality of the impact member 22 for each test.
In specific application, the detection equipment can be arranged on the base 1 or the key replacing table 12, and the detection can be directly carried out on the base 1 or the key replacing table 12 without taking down the key after each test.
The working process of the embodiment is as follows: installing a key replacing table 12 with a key to be tested on a base 1, selecting a proper pressing piece 13 and an impact piece 22, driving an acquisition device 23 to move to a set height through a lifting driver 24, retracting a telescopic piece to release the impact piece 22, enabling the impact piece 22 to freely fall along an auxiliary guide pipe 21 under the action of gravity and impact the pressing piece 13, and instantly completing impact test on the key by the pressing piece 13; the lifting driver 24 drives the acquisition device 23 to descend to the position of the impact piece 22, the telescopic piece is driven by the telescopic driver to extend into the bottom of the impact piece 22, and then the impact piece 22 is lifted to the original set height; then detecting the continuity of the key by using detection equipment, if the key function is not invalid, lifting the driving acquisition device 23 and the impact piece 22 to a new set height higher than the original set height by using a lifting driver 24, and continuing to perform an impact test until the key is damaged; the height of the impact member 22 is recorded after the key is damaged, and a new key is used to test the damaged height to determine whether the impact force is the impact threshold of the key. After the critical value of the key damage is measured, the impact energy of the impact piece 22 is calculated as the critical impact energy of the key damage, and the critical impact energy of the key can be further provided by simulating through a simulation means.
The utility model provides a button impact testing device, it acquires impact piece 22 through acquisition device 23, then through lift drive arrangement drive acquisition device 23 and impact piece 22 to setting for the height, acquisition device 23 releases impact piece 22 again, impact piece 22 tenesmus and exerts the impact force in the twinkling of an eye to pressing piece 13, pressing piece 13 presses the button that awaits measuring in the twinkling of an eye to test the shock resistance of button; moreover, different degrees of impact force can be applied by adjusting the height of the impact member 22 and replacing impact members 22 of different sizes; the button of different volumes is pressed to the accessible change different pressers 13, and the practicality is strong and application scope is wide.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
