[0002] The electronic universal testing machine is a precision instrument used for testing the mechanical properties of materials. It is widely used in scientific research, quality inspection, manufacturing and other fields to help evaluate the strength, toughness, elasticity and other properties of materials. Its high-precision sensors and automated control system ensure the accuracy and reliability of the test data.

[0003] The modular and expandable electronic universal testing machine is based on the traditional electronic universal testing machine. Its core components (fixtures) can be disassembled and replaced as needed to adapt to the requirements of different materials and testing standards. The equipment combines flexibility and accuracy, is easy to upgrade and maintain, and is widely used in scientific research, new material development and other scenarios that require diversified testing.

After the insert plate 21 disengages from the clamping frame 19, the testing machine clamp 21 can be pulled out along the fourth slide groove 18 and replaced. During the compression test, the object is placed on the anti-slip plate 23 below, and then the hydraulic cylinder 17 is opened. The output end of the hydraulic cylinder 17 drives the plate 2 to move downward, thereby compressing the object. The anti-slip plate 23 provides anti-slip treatment to prevent the object from shifting or falling off. When the anti-slip plate 23 has been used for a long time, it needs to be replaced. Pull the push rod 6 by the pull bar 24. The push rod 6 presses the first spring 11 and moves along the inner wall of the moving groove 25. After the push rod 6 disengages from the anti-slip plate 23, the anti-slip plate 23 can be pulled away along the fifth sliding groove 22, thereby disassembling and replacing it.
