Problems solved by technology

[0004] However, when the operator uses the above method to debug the impact testing machine, it needs to debug 5 times on average to get the proper adjustment parameters.
This often requires a lot of debugging time, which not only affects the work efficiency but also reduces the service life of the impact testing machine

Embodiment Construction

[0020] see figure 1 and figure 2 , the impact testing machine 100 according to the preferred embodiment of the present invention includes an impact device 10 and a control system 30 electrically connected to the impact device 10 .

[0021] The impact device 10 includes a lifting mechanism 11 , an impact head 13 , a cylinder 15 opposite to the impact head 13 , and a bearing platform 17 fixed to the end of the impact head 13 away from the cylinder 15 . The lifting mechanism 11 is connected to the bearing platform 17, and the lifting mechanism 11 automatically adjusts the bearing platform 17 under the control of the control system 30, thereby adjusting the distance between the end surface of the impact head 13 and the surface of the cylinder 15, that is, the drop height of the impact head 13. After the lifting mechanism 11 releases the bearing platform 17, the impact head 13 and the bearing platform 17 do free fall together until impacting the cylinder 15. 15 rebounds. In thi...

Abstract

The invention relates to a shock test machine which comprises a shock device and a control system. The control system comprises a master controller, and the shock device comprises a lifting mechanism, an impact head driven by the lifting mechanism and an air cylinder arranged opposite to the impact head. The lifting mechanism under control of the master controller adjusts the falling height of the impact head automatically. The master controller further comprises a conversion module and a control module. The conversion module is used to calculate the falling height needed to be adjusted for the impact device and a value of the pressure of the air cylinder according to a predetermined value of acceleration and a predetermined time of residence. The control module is used to control the lifting mechanism to adjust the falling height of the impact head according to the value of the falling height obtained through calculation and adjust the pressure of the air cylinder according to the value of the pressure of the air cylinder. The shock test machine has higher work efficiency and a longer service life. The invention further relates to a method for carrying out the shock test by the shock test machine.

Description

technical field [0001] The invention relates to an impact testing machine, in particular to an impact testing machine for impact testing portable electronic devices and a method for performing impact testing. Background technique [0002] After the portable electronic device is manufactured, samples are generally sampled for impact testing to verify its assembly quality. An existing impact testing machine includes an impact head, a piston cylinder opposite to the impact head, and a bearing platform fixed to the end of the impact head away from the piston cylinder. The carrying platform is used to carry the portable electronic device to be tested. When performing the test, it is necessary to debug the various parameters of the impact testing machine to obtain a suitable combination of adjustment parameters, so that the impact testing machine can obtain the required impact parameters when performing the impact test. The impact parameters of the impact testing machine are gen...
