An automatic test system for impact sensitivity

Abstract

The invention relates to an automatic impact sensitivity test system. The automatic impact sensitivity test system mainly comprises an impact test apparatus, a conveying apparatus, a robot and a control unit; the impact test apparatus is used for hammer lifting test and acquiring test data, the conveying apparatus is used for storing a to-be-tested and tested initiating explosive device test samples, the robot is used for automatically fetching and storing the to-be-tested tested and tested initiating explosive device test samples, and the control unit is separately electrically connected withthe impact test apparatus, the robot and the conveying apparatus. The system is high in automation degree, high in test precision, safe and reliable.

Description

technical field [0001] The invention belongs to testing and measuring technology, in particular to an automatic testing system for impact sensitivity. Background technique [0002] In the pyrotechnics industry, it is necessary to conduct impact tests on energetic materials such as pyrotechnics for testing and calibration at all stages of R&D, production, and testing. When used for testing, it is necessary to perform a fixed drop height impact test on a batch of samples to test whether the batch of samples is qualified; while for calibration, a characteristic drop height test is required, and the next weight test should be adjusted according to whether the sample explodes or not. Hammer height to test the excitation height of the sample weight hammer. Regardless of whether it is used for testing or calibration, the falling process of the heavy hammer should be similar to free fall, and it is necessary to accurately test the speed and energy of the heavy hammer at the moment ...

Problems solved by technology

The measurement error of this method is very large, it varies from time to time, and the randomness is large, and the test results can only be judged qualitatively and cannot be quantified. In many cases, the sound and light are not obvious, resulting in misjudgment and hidden dangers in the use of pyrotechnics , and more than ten of the test personnel are at the test site, the labor intensity of the personnel is high, and the safety is low

[0004] The existing impact sensitivity test equipment has a heavy hammer that is pulled up by a steel wire connected to the hammer head. There is no guiding measure during the falling process, and eccentricity often occurs. When the heavy hammer rebounds after impact, the tester needs to tighten the steel wire again, requiring rapid response. , Sometimes if the response is not timely, it will cause a secondary impact on the pyrotechnics, and the reliability cannot be guaranteed

At the same time, whether the sample explodes after the impact of the heavy hammer needs to be judged manually. The human ear is used to judge the explosion sound, the human eye observes the explosion light, and the human smells the test gas to judge. The measurement error varies from person to person and from time to time. There are also harmful ingredients to the human body, and long-term exposure will cause adverse effects on the human body
