Description

Technical Field

[0001] This utility model belongs to the field of impact force testing technology, specifically relating to an electromagnet-lifted vertical impact force testing device. Background Technology

[0002] In mechanical engineering, impact testing of products or parts is very common. Impact testing can verify the reliability of workpieces under actual working conditions. Many workpieces (such as automotive parts) are subjected to sudden impacts. The test simulates these extreme conditions to ensure that the workpieces will not fail.

[0003] Currently, the common counterweight lifting mechanisms in vertical impact force testing devices are usually sprocket lifting type and servo electric cylinder lifting type. The former requires a relatively complex sprocket structure, while the latter is equipped with an expensive servo electric cylinder. Furthermore, both of these counterweight lifting methods require an additional pneumatic locking mechanism to keep the counterweight platform at the required height, resulting in complex structures and high equipment costs. Therefore, we propose an electromagnet lifting type vertical impact force testing device. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model includes an impact force testing support assembly, a counterweight guiding assembly, and a winch magnetic attraction assembly. In use, the workpiece to be tested is bolted onto the support base. Then, according to the testing requirements, the required number of counterweights are bolted onto the counterweight plate.
