[0002] Gravel impact testing machine refers to a material testing machine that applies impact test force to the sample and conducts impact test. Impact testing machines are divided into semi-automatic impact testing machines, digital display impact testing machines, microcomputer-controlled impact testing machines, drop hammer impact testing machines, and non-metallic impact testing machines. With the development and progress of society, people's demand for resistant gravel impact testing machines is increasing. Gravel impact testing machines are mainly used to simulate the resistance of single-layer and multi-layer paint coatings or similar coatings on vehicles and other vehicles on the road and track to high particle impact resistance, and accurately reflect the damage caused by splashing sand and gravel. During the experiment, the object is clamped in one place by a fixing device, and then the gravel is driven to impact the object through the gun assembly. Since the object is fixed in one place, although the gravel has a wide coverage when impacting, it can impact most of the object, but there are still blind spots in the experiment, resulting in incomplete impact test of the object, affecting the accuracy of the results. For this reason, we propose a gravel impact testing machine for automobile anti-sand collision test. Utility Model Content
