Description

Technical Field

[0001] This application relates to the field of material mechanical property testing technology, specifically a static testing device capable of temperature environment regulation. Background Technology

[0002] Static testing of materials is an important means of evaluating the mechanical properties of materials and is widely used in the research and development and quality control of engineering materials. With the development of industrial technology, the demand for performance testing of materials under different environmental conditions is increasing, especially the performance testing under extreme temperature environments. Static testing equipment is used to apply static loads to structures or components to simulate the actual stress state and test their mechanical properties, load-bearing capacity, deformation characteristics and other key indicators. By precisely controlling the applied force value, direction and point of application, it can comprehensively and deeply obtain the response data of the test object under static load, such as stress, strain and displacement, providing professional and critical data support for engineering design, structural evaluation and material research and development. It highlights its core function of accurately simulating and quantitatively analyzing the performance of objects under static load.

[0003] However, existing static testing equipment, which mainly includes a loading system, a fixture system, and a data acquisition system, lacks a temperature environment simulation system, resulting in poor applicability of the equipment. When it is necessary to simulate tests under different temperature environments, external equipment is usually required. However, external equipment can cause uneven heating and cooling, affecting the test results and accuracy. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a static testing device capable of temperature environment regulation. This device can uniformly heat or cool the sample, achieving temperature regulation to facilitate testing under high or low temperature conditions, thus improving the device's applicability. It solves the problem that existing technologies lack a temperature environment simulation system, leading to poor device applicability. Furthermore, when simulating tests under different temperature environments, external equipment is typically required, which can cause uneven heating and cooling, potentially affecting test results and accuracy.

[0005] To achieve the above objectives, this application provides the following technical solution: a static testing device capable of temperature environment regulation, comprising a base plate, a storage tank disposed on the upper surface of the base plate, a mounting base fixedly mounted on the upper surface of the base plate, two infrared heaters fixedly mounted on the upper surface of the mounting base, a support frame fixedly mounted on the upper surface of the base plate, a telescopic rod fixedly connected to the upper surface of the support frame, a connecting pipe fixedly mounted at the output end of the telescopic rod, nozzles arranged at equal intervals fixedly mounted on the outer surface of the connecting pipe, a pump body fixedly mounted on the upper surface of the storage tank via a pipe, the bottom surface of the pump body fixedly connected to the upper surface of the support frame, a flexible hose fixedly mounted at the output end of the pump body, a stainless steel pipe fixedly connected to the other end of the flexible hose, the outer surface of the stainless steel pipe slidably connected to the inner wall of the support frame, the bottom end of the stainless steel pipe fixedly connected to the outer surface of the connecting pipe, and a temperature sensor disposed above the base plate.

[0006] In order to improve the applicability of the device by adjusting the temperature of the sample to simulate high or low temperature testing environments, the above scheme is implemented by placing the storage tank on the upper surface of the base plate and connecting the pump to the storage tank. When the sample is clamped, the infrared heater installed on the upper surface of the mounting base heats the sample. When cooling is required, the pump is started to extract liquid nitrogen from the storage tank, pressurize it through the pump, and deliver it to the hose. The liquid nitrogen is then delivered to the connecting pipe through the hose and stainless steel pipe, and then sprayed out through the nozzle on the surface of the connecting pipe. The liquid nitrogen is sprayed onto the surface of the sample to cool it. A temperature sensor is installed to detect the surface temperature of the sample in real time. Thus, the device can achieve uniform heating or cooling of the sample through the infrared heater, liquid nitrogen delivery mechanism, and nozzle, thereby achieving the effect of adjusting the sample temperature to simulate high or low temperature testing environments and improve the applicability of the device.

[0007] Furthermore, an upper clamp is fixedly installed at the output end of the telescopic rod, a lower clamp is fixedly installed on the upper surface of the mounting base, and a baffle is provided on the upper surface of the base plate.

[0008] The above scheme involves installing the upper clamp at the output end of the telescopic rod and setting it as a fixed connection. By extending and shortening the telescopic rod, the upper clamp can be lowered, and the lower clamp is fixed to the upper surface of the mounting base. The sample is placed on the surface of the lower clamp, and the upper clamp is lowered by the telescopic rod. Thus, the sample can be clamped and fixed by the upper and lower clamps. A baffle is installed on the upper surface of the base plate. The baffle can limit the right end of the sample and prevent the sample from shifting when pressure is applied to the sample.

[0009] Furthermore, a limiting frame is fixedly installed on the upper surface of the base plate, and a hydraulic rod is fixedly installed on the inner wall of the limiting frame.

[0010] The above method involves installing the limit frame on the upper surface of the base plate to achieve the installation of the limit frame, and installing the hydraulic rod on the inner wall of the limit frame as a fixed connection to achieve the installation of the hydraulic rod.

[0011] Furthermore, a force sensor is fixedly installed at the output end of the hydraulic rod, and a top block is fixedly installed on the right side of the force sensor.

[0012] The above scheme involves installing a force sensor at the output end of a hydraulic rod, which allows the force sensor to move. A top block is installed on the right side of the force sensor, and the hydraulic rod allows both the force sensor and the top block to move. The top block presses the sample firmly against the sample, and the force sensor detects the real-time pressure.

[0013] Furthermore, a crossbar is fixedly installed on the front of the support frame, and a motor is fixedly connected to the left side of the crossbar.

[0014] The above method involves installing the crossbar on the front of the support frame, and then installing the motor on the front of the support frame as a fixed connection.

[0015] Furthermore, the output shaft of the motor is fixedly connected to a threaded rod, and the outer surface of the threaded rod is rotatably connected to the inner wall of the crossbar.

[0016] The above scheme involves mounting the threaded rod on the output shaft of the motor as a fixed connection, allowing the threaded rod to rotate via the motor, and connecting the threaded rod to the crossbar as a rotatable connection to limit the movement of the threaded rod.

[0017] Furthermore, the outer surface of the threaded rod is threaded with a slider, and the outer surface of the slider is slidably connected to the inner wall of the crossbar.

[0018] The above scheme involves mounting the slider on the surface of the threaded rod, setting it as a threaded connection, and connecting the outer surface of the slider to the inner wall of the crossbar. When the threaded rod rotates, the slider can slide on the inner wall of the crossbar.

[0019] Furthermore, a laser interferometer is fixedly mounted on the back of the slider, and the back of the slider is fixedly mounted to the front of the temperature sensor.

[0020] With the above scheme, the laser interferometer is installed on the back of the slider, and the temperature sensor is also installed on the back of the slider. The laser interferometer can measure the deformation of the sample surface through the principle of optical interference, thereby indirectly reflecting the stress change. The temperature sensor can detect the temperature data of the sample in real time. When the slider moves, the laser interferometer and the temperature sensor can move together to adjust their positions.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This static testing device, capable of temperature environment regulation, comprises components such as an infrared heater, stainless steel pipe, connecting pipe, and nozzle. A temperature sensor detects the sample temperature. When heating is required, the infrared heater is activated to raise the sample temperature. When cooling is required, a pump is activated to draw liquid nitrogen, which is then delivered through a hose, stainless steel pipe, and connecting pipe, and sprayed onto the sample surface through the nozzle to lower the sample temperature. This device achieves uniform heating or cooling of the sample through the infrared heater, liquid nitrogen delivery mechanism, and nozzle, thus regulating the sample temperature for simulating high or low temperature environments and improving the device's applicability. A motor rotates a threaded rod, which, through its connection to a slider, slides along the inner wall of a crossbar. This slider, in turn, moves the laser interferometer and temperature sensor laterally, facilitating the detection of different positions on the sample. Attached Figure Description

[0039] Please see Figure 6 A laser interferometer 23 is fixedly mounted on the back of the slider 22. The back of the slider 22 is fixedly mounted on the front of the temperature sensor 24. The laser interferometer 23 is mounted on the back of the slider 22, and the temperature sensor 24 is also mounted on the back of the slider 22. The laser interferometer 23 can measure the deformation of the sample surface through the principle of optical interference, thereby indirectly reflecting the stress change. The temperature sensor 24 can detect the temperature data of the sample in real time. When the slider 22 moves, the laser interferometer 23 and the temperature sensor 24 can move together to adjust their positions.

[0040] This embodiment describes a static testing device capable of temperature environment regulation. It includes components such as an infrared heater 4, a stainless steel tube 9, a connecting pipe 10, and a nozzle 11. A temperature sensor 24 detects the sample temperature. When heating is required, the infrared heater 4 is activated to raise the sample temperature. When cooling is required, the pump 7 is activated to extract liquid nitrogen. The liquid nitrogen is transported through a hose 8, stainless steel tube 9, and connecting pipe 10, and sprayed onto the sample surface through the nozzle 11 to lower the sample temperature. This device achieves uniform heating or cooling of the sample through the infrared heater 4, liquid nitrogen delivery mechanism, and nozzle 11, thus regulating the sample temperature for simulating high or low temperature environments and improving the device's applicability. A motor 20 rotates a threaded rod 21, which, through its connection to a slider 22, slides on the inner wall of a crossbar 19. This causes the slider 22 to move the laser interferometer 23 and temperature sensor 24 laterally, facilitating the detection of different positions on the sample.

[0041] It should be noted that the infrared heater 4 is existing technology. It can achieve the heating effect by being installed on the surface of the mounting base 3. The telescopic rod 6 is electrically driven, which enables the upper clamp 13 to be raised and lowered. The motor 20 is a servo motor, which realizes the forward and reverse rotation of the threaded rod 21, thereby enabling the threaded rod 21 to drive the slider 22 to slide laterally on the inner wall of the crossbar 19. A support assembly is provided on the right side of the baffle 14, which can support the baffle 14. The temperature sensor 24 is an infrared thermometer, which realizes the detection of the surface temperature of the sample.

[0042] The working principle of the above embodiments is as follows:

[0043] First, the sample is placed on the lower clamp 12. Then, the telescopic rod 6 is activated, causing the upper clamp 13 to descend. The upper clamp 13 and the lower clamp 12 clamp and position the sample. The temperature of the sample is then detected by the temperature sensor 24. When heating the sample is required, the infrared heater 4 is activated to raise the sample temperature. When cooling is required, the pump 7 is activated to extract liquid nitrogen from the storage tank 2 through the pipeline. The liquid nitrogen is transported through the hose 8, stainless steel pipe 9, and connecting pipe 10, and sprayed onto the surface of the sample through the nozzle 11 to cool the sample. Thus, this device can achieve uniform heating or cooling of the sample through the infrared heater 4, the liquid nitrogen delivery mechanism, and the nozzle 11, thereby achieving temperature regulation of the sample. The device is designed to simulate high or low temperature environments, improving its applicability. Before testing, the motor 20 is started to rotate the threaded rod 21. Through the connection between the threaded rod 21 and the slider 22, the slider 22 slides on the inner wall of the crossbar 19, thereby causing the slider 22 to drive the laser interferometer 23 and the temperature sensor 24 to move laterally and adjust the detection position of the sample. After debugging, the hydraulic rod 16 is started to push the sample with the force sensor 17 and the top block 18. The right end of the sample is limited by the baffle 14. The pressure is detected in real time by the force sensor 17 and pressure is applied by the hydraulic rod 16. Then, the laser interferometer 23 can measure the deformation of the sample surface through the principle of optical interference, thereby indirectly reflecting the stress change.
