Embodiment Construction

[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

A shock test device comprises a test board, a stand column, a support plate, a shock sleeve and a shock hammer. The stand column is fixed on the test board, the support plate is fixedly connected with the stand column, an interval is formed between the support plate and the test board, the shock sleeve is fixed on the support plate, an intercepting hole is formed in the side wall of the shock sleeve, the shock hammer can drop on the test board through the intercepting hole, a solenoid valve is arranged on the outer side of the shock sleeve, and the valve core of the solenoid valve can stretch into the intercepting hole to clamp the shock hammer. The shock test device controls the connection and disconnection of the solenoid in shock process to enable the valve core of the solenoid valve to stretch into the shock sleeve through the intercepting hole on the side of the shock sleeve, and to stop the shock hammer which shocks from rebounding and falling down again, and thus a secondary shock to a testing part caused by rebound of the shock hammer is avoided. The invention further provides a shock test method.

Description

【Technical field】 [0001] The invention relates to a test device and method, in particular to an impact test device and method. 【Background technique】 [0002] The mechanical shock test refers to the action of electrical equipment when it is subjected to a standard impact hammer falling vertically from a height h. The height h is derived from the impact energy E (h=E / 10) to examine the strength of the product shell. During the impact, because the impact hammer rushes to the surface of the impacted part, affected by the rebound force, the impact hammer will bounce again and perform a second impact on the impacted part: 1. It affects the accuracy of the test; 2. The impact hammer rebounds Sometimes it will run off and jump out, which will affect the safety of the operator. 【Content of invention】 [0003] In view of the above situation, it is necessary to provide an impact test device and method capable of preventing secondary impact. [0004] An impact test device, compris...
