[0002] An impact testing machine refers to a material testing machine that applies an impact test force to a specimen and performs an impact test. An impact testing machine is a detector used to measure the ability of metal materials to resist impact under dynamic loads, thereby determining the quality of the material under dynamic loads. A pendulum impact testing machine has various types of pendulums according to the impact energy. Different pendulums have different pendulum weights and pendulum lengths. A pendulum impact test requires measuring the vertical downward force F when the pendulum is in a horizontal position and the distance from the point of action of the force F to the center of the pendulum shaft. At present, there are two calibration methods for pendulum impact testing machines: direct calibration method and indirect calibration method. The types and methods of calibration of this type of impact testing machine calibration device are not diverse enough and cannot adapt to calibration in different situations; therefore, it does not meet existing needs. In this regard, we propose an impact testing machine calibration device. Utility Model Content
