Shock test device and method

Abstract

The invention discloses a shock test device which is characterized in that an insertion hole is formed in the side wall at one end of a sleeve, a supporting piece is fixed on the outer side wall of the sleeve, one end of a pulling rod can extend into the insertion hole, the middle of the pulling rod is movably connected with the supporting piece, a driving piece is fixedly connected with the other end of the pulling rod, and a shock hammer can enter the sleeve from one end, away from the insertion hole, of the sleeve and fall down from the other end of the sleeve. A photoelectric inductive assembly is arranged at one end, close to the insertion hole, of the sleeve. A control module is electrically connected with the driving piece and the photoelectric inductive assembly. When the shock hammer falls down from the sleeve, the photoelectric inductive assembly is triggered to generate an inductive signal on the control module. When the shock hammer rebounds again to enter the sleeve, the control module controls the driving piece to work, the driving piece drives the pulling rod to move relative to the supporting piece, and one end of the pulling rod extends into the insertion hole to intercept the shock hammer. The shock test device can protect the shock hammer against secondary shock. 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] In the usual test work in the laboratory, the strength of the lamp shell is often tested, and the impact test is used to investigate. There is such a regulation in the GB3836.1 standard: the glass transparent parts should be tested on three samples, and each sample is only Test once, other parts should be tested on two samples, and each sample should be tested once at two different positions. However, in the actual operation process of the laboratory at present, because the impact hammer is in free fall in the sleeve, it hits the point to be impacted. Since it is a sleeve, the impact hammer will bounce back after hitting the object during the impact process. , and then drop it again, and hit the object again, which will repeatedly hit N times, so that the transparent part will be hit many times, and the test result wi...

However, in the actual operation process of the laboratory at present, because the impact hammer is in free fall in the sleeve, it hits the point to be impacted. Since it is a sleeve, the impact hammer will bounce back after hitting the object during the impact process. , then drop it again, and hit the object again, which will repeatedly hit N times, so that the transparent part will be hit many times, and the test result will be inaccurate, and it will not meet the test standard.
