A moving crossbeam is provided below the support crossbeam. A spiral pressing plate clamping device 8 is provided on the crossbeam and is slidably connected to the moving crossbeam. Control and display systems 9 are provided on the left and right sides in front of the fuselage frame 2.
[0029] Preferably, a horizontal hydraulic press device is fixedly connected to the left and right sides of the right side of the fixed platform. The horizontal hydraulic press device is parallel to the moving crossbeam and perpendicular to the spiral pressing plate clamping device 8, and is used to apply a stable and adjustable thrust in the horizontal direction to the specimen to ensure the stability of the movement and meet the requirements of different force tests.
[0030] Preferably, the microscopic observation device 3 includes a magnifying glass 16 and a capture camera 17. The magnifying glass 16 and the capture camera 17 can move along the guide rail to adapt to parts of different sizes. The magnifying glass 16 and the capture camera 17 are fixedly connected, and a rotating shaft 15 is provided on the side of the microscopic observation device 3 facing the observation window 4, making the observation process more flexible and capable of capturing the subtle changes of the material during the stretching process in real time.
[0031] Preferably, the spiral pressing plate clamping device 8 is connected to the moving crossbeam through a sliding connection, realizing the precise clamping and positioning of the specimen. This device adopts a combined design of a screw pair, a pressing plate and a spigot gasket, ensuring the uniform distribution of the clamping force and the stability of the specimen during the test.
[0032] Preferably, the observation window 4 forms a 45-degree angle with the horizontal plane of the fuselage base 1 and is made of a transparent high-strength material. The observation window 4 can be opened, facilitating observation, avoiding accidental injuries during the test, and being easy to clean.
[0033] Preferably, the screw pressing plate clamping device 8 is connected to a force sensor and a displacement sensor, which are used to collect force and displacement data in real time, and set experimental parameters, control the experimental speed, start and stop the experiment through the control and display system 9, and display the force-displacement curve and experimental data in real time.
[0034] Working principle:
[0035] The specimen is placed on the fixed table 6. Under the command of the control system, the vertical hydraulic press device 7 generates high-pressure hydraulic oil through a hydraulic pump, drives the piston in the hydraulic cylinder to move downward, applies a vertical pressure to the specimen workpiece, and fixes one end of the specimen workpiece on the fixed table 6.
[0036] The other end of the specimen workpiece is clamped by the screw pressing plate clamping device 8. Before the clamping operation, the pressing plate 12 is in a loose state and maintains a certain distance from the specimen workpiece. When it is necessary to clamp the workpiece, by rotating the nut 11 at the head of the screw 10, the nut 11 starts to rotate around the spiral coil of the screw 10. As the nut 11 rotates, its spiral coil will push the stop gasket fixed on the pressing plate to move along the axis direction of the spiral coil. This movement will drive the pressing plate to approach the specimen workpiece. When the pressing plate contacts the workpiece and continues to move, a clamping force will be generated. As the nut 11 rotates further, the clamping force gradually increases until the required clamping degree is reached. The screw pressing plate clamping device 8 uses the rotational movement of the screw pair to drive the pressing plate to apply a uniform clamping force to the specimen, ensuring the specimen remains stable during the test.
[0037] The screw pressing plate clamping device 8 is slidably connected to the moving crossbeam and can move horizontally along the moving crossbeam, thereby realizing the precise positioning of the specimen. The horizontal hydraulic press devices fixedly connected to both sides of the fixed table 6 are started. The horizontal hydraulic press devices are parallel to the moving crossbeam and perpendicular to the screw pressing plate clamping device 8, providing a horizontal and stable thrust to test the deformation of the specimen under tension. The magnitude of the tension can be precisely adjusted through the control system to meet different test requirements. During the tensile process of the specimen, the microscopic observation device 3 observes the changes of the specimen in real time through the magnifying glass 17 and the capture camera 16, including the generation and expansion of cracks, etc. The cylindrical LED lighting tube 5 provides sufficient and uniform light source to ensure the clarity and accuracy of the observation results. The capture camera 16 transmits the observed images to the control and display system 9 for subsequent data analysis and processing.
[0038] The screw pressing plate clamping device 8 is connected to a force sensor and a displacement sensor, which measure and record the mechanical parameters of the specimen during the tensile process in real time. These parameters are processed and analyzed by the control and display system to obtain the mechanical property indexes of the specimen such as tensile strength, yield strength, elongation rate, etc.
[0039] When the specimen reaches the set tensile force or displacement, the control and display system 9 issues a stop signal, the hydraulic cylinder stops working, and the test ends.
[0040] The control and display system 9 processes and analyzes the data collected during the test, generates test reports and charts for users to reference and evaluate.
