[0002] The torsion test machine fixture is a device used to clamp the sample and apply the torsion force in the torsion test. The design of the torsion test machine fixture is crucial to ensure accurate test results. The torsion test machine fixture usually includes two sets of clamping clamps for clamping the sample to apply the torsion force. These clamps are usually designed to be adjustable to accommodate samples of different sizes and shapes. The clamping clamps usually have a variety of clamping surfaces, such as toothed, smooth or rubber covered, to ensure that the sample can be firmly clamped without slipping or damage. The torsion test machine fixture usually includes a rotating device for applying the torsion force to the sample. This rotating device is usually driven by a motor, which can control the torsion speed and torsion angle. The rotating device needs to have sufficient precision and stability to ensure the accuracy of the test results. Sometimes, the torsion test needs to be carried out under specific conditions, such as high temperature, low temperature or humidity. In this case, the sample fixture can be used to fix the sample and provide the required environmental conditions. To ensure the safety of operators and equipment, the torsion test machine fixture is also equipped with safety devices such as emergency stop buttons, overload protection and protective covers.
[0003] The torsion testing machine fixture is a crucial component in the torsion test. Its design and performance directly affect the accuracy and reliability of the test results.
[0004] Most of the existing torsion testing machine fixtures have one end fixed and the other end movable, which cannot be applied to situations where both ends are adjustable in some specific cases. Therefore, it is necessary to develop a torsion testing machine fixture that can adjust the fixed position more flexibly. Utility Model Content
