Introduction to the structure of the test machine fixture

Everyone knows that there are many types of tests. According to different test requirements, different fixtures are used for different materials.Testing machineThe fixture is visible to be of unique importance, and it depends on the different samples and test force.,Very different structure.(Samples with large test forces generally adopt a bevel clamping structure,As the test force increases,The clamping force increases accordingly, and the shoulder sample adopts a suspended structure, etc.), If the fixture is divided by structure, it can be divided into wedge-shaped fixtures (referring to fixtures that adopt the principle of inclined locking), clamp type fixtures (referring to fixtures that adopt the principle of single-sided or double-sided threaded top tightening), winding fixtures (referring to fixtures that use the sample to be locked by winding), eccentric fixtures refer to fixtures (referring to fixtures that use the principle of eccentric locking), lever type fixtures (referring to fixtures that use the principle of lever force amplification), shoulder type fixtures (referring to fixtures that use the principle of shoulder sample), bolt type fixtures (referring to fixtures that use the principle of test thread strength such as bolts, screws, studs, etc.),90°Peeling fixtures (referring to fixtures suitable for hanging and straight peeling of two samples) and so on. The structures of these fixtures have their own advantages and disadvantages. For example, wedge-shaped fixtures have a small initial clamping force, and as the test force increases, the clamping force increases accordingly. For clamping fixtures, the initial clamping force is large and increases with the test force. The clamping force decreases accordingly.
