Description
A stainless steel temperature tensile deformation monitoring device Technical Field
[0001] This utility model relates to the field of tensile deformation monitoring technology, and in particular to a stainless steel temperature-interval tensile deformation monitoring device. Background Technology
[0002] Tensile deformation monitoring devices are equipment used to accurately measure the deformation of materials and structures when subjected to tensile forces. They are widely used in materials science, engineering mechanics, civil engineering and other fields to study the mechanical properties of materials, the safety of structures and deformation laws.
[0003] In existing technologies, stainless steel temperature-dependent tensile deformation monitoring devices typically use extensometers. The extensometer directly contacts the sample to measure the change in distance between two gauge points, thereby measuring the deformation value of the sample during the tensile process. However, the direct contact with the sample and the difference in thermal expansion between the extensometer and the sample at high temperatures can cause errors, resulting in inaccurate monitoring results from stainless steel temperature-dependent tensile deformation monitoring devices. Summary of the Invention
[0004] The purpose of this invention is to solve the problem in the existing technology that the difference in thermal expansion between the extensometer and the sample at high temperatures will cause errors, resulting in inaccurate monitoring results of stainless steel temperature tensile deformation monitoring devices. Therefore, this invention proposes a stainless steel temperature tensile deformation monitoring device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stainless steel temperature tensile deformation monitoring device, comprising a workbench, a monitoring box being provided on the outer surface of the workbench, a row of spotlights being provided on one side of the outer surface of the monitoring box, a sensor being provided on the other side of the outer surface of the monitoring box, a motor being provided on one side edge of the outer surface of the monitoring box, an output shaft being fixedly connected to the output end of the motor, a rotating shaft being fixedly sleeved on the outer surface of the output shaft, and a gear being fixedly sleeved on one end of the outer surface of the rotating shaft.
[0006] Preferably, the outer surface of the output shaft is movably embedded in the inner wall of the monitoring box, the outer surface of the rotating shaft is movably embedded in the inner wall of the monitoring box, and two first sliding grooves are formed in the inner wall of the monitoring box.
[0007] Preferably, the inner walls of both first slide grooves are slidably connected to first sliders, the outer surfaces of both first sliders are fixedly connected to first moving blocks, and the outer surfaces of both first moving blocks slide against the inner wall of the monitoring box.
[0008] Preferably, a second moving block is fixedly connected to the outer surface of each of the two first moving blocks near one end, and a clamping head is provided on the outer surface of each of the two second moving blocks near one edge, and a first toothed row is fixedly connected to the outer surface of one of the first moving blocks near one edge.
[0009] Preferably, a second gear rack is fixedly connected to the outer surface of another first movable block near one side edge, and the outer surfaces of both the first and second gear racks mesh with the outer surface of the gear.
[0010] Preferably, the outer surfaces of the first and second tooth rows are both fixedly connected to the second slider, and two second sliding grooves are opened in the inner wall of the monitoring box.
[0011] Preferably, the inner walls of the two second sliding grooves are slidably connected to the outer surfaces of the two second sliders, and a fixing block is fixedly connected to the other outer surface of the monitoring box, with a controller provided on the outer surface of the fixing block.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, the device sets up a spotlight array on one side of the monitoring box and a sensor on the other side. The clamping head holds the sample between the spotlight array and the sensor. The light emitted from the spotlight array shines on the sensor, while the sample being tested blocks part of the light line. When monitoring the tensile deformation of the sample, the tensile deformation of the sample is monitored by detecting the light line on the sensor that is not receiving the light emitted from the spotlight array. This avoids direct contact with the sample, thus preventing thermal expansion differences when the monitoring device contacts the sample, and ensuring the accuracy of the monitoring results of the stainless steel temperature tensile deformation monitoring device.
[0014] 2. In this utility model, the device is equipped with a motor. The rotation of the motor will drive the gear to rotate. The rotation of the gear will simultaneously drive the two second moving blocks to move in opposite directions. When the second moving blocks move, they will drive the clamping head to move. By driving the two clamping heads to move at the same time, the consistency of the tensile force on both ends of the sample can be ensured. Attached Figure Description

Detailed Implementation
[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Example 1: As shown in Figures 1-7, this utility model provides a stainless steel temperature tensile deformation monitoring device, including a workbench 1, a monitoring box 2 set on the outer surface of the workbench 1, a spotlight array 3 set on one side of the outer surface of the monitoring box 2, a sensor 4 set on the other side of the outer surface of the monitoring box 2, a motor 5 set near one edge of the outer surface of the monitoring box 2, an output shaft 6 fixedly connected to the output end of the motor 5, a rotating shaft 7 fixedly sleeved on the outer surface of the output shaft 6, a gear 8 fixedly sleeved on one end of the outer surface of the rotating shaft 7, the outer surface of the output shaft 6 movably embedded in the inner wall of the monitoring box 2, the outer surface of the rotating shaft 7 movably embedded in the inner wall of the monitoring box 2, and two first sliding grooves 9 formed in the inner wall of the monitoring box 2. The inner walls of the slide grooves 9 are slidably connected to the first sliders 10. The outer surfaces of the two first sliders 10 are fixedly connected to the first moving blocks 11. The outer surfaces of the two first moving blocks 11 slide against the inner walls of the monitoring box 2. The outer surfaces of the two first moving blocks 11 are fixedly connected to the second moving blocks 12 near one end. The outer surfaces of the two second moving blocks 12 are provided with clamping heads 13 near one edge. The outer surface of one of the first moving blocks 11 is fixedly connected to the first toothed row 14 near one edge. The inner walls of the two second slide grooves 17 are slidably connected to the outer surfaces of the two second sliders 16 respectively. The other outer surface of the monitoring box 2 is fixedly connected to the fixing block 18. The outer surface of the fixing block 18 is provided with a controller 19.
[0026] The overall effect of Embodiment 1 is as follows: During the use of a stainless steel temperature tensile deformation monitoring device, the operator first needs to fix the sample to the two clamping heads 13, then control the temperature inside the monitoring box 2 through the controller 19, and simultaneously activate the spotlight array 3 and the sensor 4. Then, the operator starts the motor 5, which drives the output shaft 6 to rotate. When the output shaft 6 rotates, its outer surface rotates on the inner wall of the monitoring box 2, and simultaneously drives the rotating shaft 7 to rotate. The outer surface of the rotating shaft 7 rotates on the inner wall of the monitoring box 2, and at the same time, the rotating shaft 7 drives the gear 8 to rotate. The gear 8 simultaneously drives the first gear row 14 and the second gear row 15 to move. When the first gear row 14 and the second gear row 15 move, they drive the first moving block 11 and the second slider 16 to move. The outer surface of the second slider 16 slides along the inner wall of the second slide groove 17, and the outer surface of the first moving block 11 moves in contact with the inner wall of the monitoring box 2. At the same time, the first moving block 11 drives the first slider 10 and the second moving block 12 to move. The outer surface of the first slider 10 slides along the inner wall of the first groove 9. Simultaneously, the second moving block 12 moves, causing the clamping head 13 to move as well. The two clamping heads 13 move towards and away from each other to stretch the sample. At this time, the light emitted from the spotlight array 3 illuminates the sensor 4, while the outer surface of the sample partially blocks the light. The shadowed area on the sensor 4 that does not receive light represents the tensile deformation of the sample. This device, by setting the spotlight array 3 on one side of the monitoring box 2 and the sensor 4 on the other side, clamps the sample between the spotlight array 3 and the sensor 4. The light emitted from the spotlight array 3 illuminates the sensor 4, while the sample being tested partially blocks the light. When monitoring the tensile deformation of the sample, the tensile deformation of the sample is monitored by detecting the shadowed area on the sensor 4 that does not receive light. This solves the problem of inaccurate monitoring results caused by the difference in thermal expansion between the extensometer and the sample at high temperatures.
[0027] Example 2: As shown in Figures 1-7, a second toothed row 15 is fixedly connected to the outer surface of another first moving block 11 near one side edge. The outer surfaces of the first toothed row 14 and the second toothed row 15 are both meshed with the outer surface of the gear 8. The outer surfaces of the first toothed row 14 and the second toothed row 15 are both fixedly connected to the second slider 16. Two second sliding grooves 17 are opened in the inner wall of the monitoring box 2.
[0028] The effect achieved by the entire embodiment 2 is as follows: During the use of a stainless steel temperature tensile deformation monitoring device, the operator needs to first fix the sample with the two clamping heads 13, start the spotlight array 3 and sensor 4, and then start the motor 5. The motor 5 will drive the output shaft 6 to rotate, the output shaft 6 will drive the rotating shaft 7 to rotate, the rotating shaft 7 will drive the gear 8 to rotate, the gear 8 will simultaneously drive the first gear row 14 and the second gear row 15 to move, the first gear row 14 and the second gear row 15 will drive the first moving block 11 to move, the first moving block 11 will drive the second moving block 12 to move, and the second moving block 12 will drive the clamping heads 13 to move. The two clamping heads 13 will move towards and relative to each other at the same time to stretch the sample. By driving the two clamping heads 13 to move at the same time, the consistency of the tensile force on both ends of the sample can be ensured.
[0029] Working Principle: In the operation of a stainless steel temperature-dependent tensile deformation monitoring device, the operator first fixes the sample to the two clamping heads 13. Then, the controller 19 controls the temperature inside the monitoring chamber 2, simultaneously activating the spotlight array 3, sensor 4, and motor 5. Motor 5 drives gear 8 to rotate, which in turn moves the first gear row 14 and the second gear row 15. This movement of the first and second gear rows 14 and 15 moves the first moving block 11, which in turn moves the second moving block 12. The second moving block 12 then moves the two clamping heads 13 simultaneously in opposite directions and relative to each other, thus stretching the sample. By simultaneously moving both clamping heads 13, the consistency of the tensile force on both ends of the sample is ensured. The light emitted from the spotlight array 3 illuminates the sensor 4, while the outer surface of the sample partially blocks the light. The shadowed area on the sensor 4 where no light is received represents the tensile deformation of the sample. This device uses a spotlight array 3 on one side of the monitoring box 2 and a sensor 4 on the other side. The clamping head 13 holds the sample between the spotlight array 3 and the sensor 4. The light emitted from the spotlight array 3 illuminates the sensor 4, while the sample being tested partially blocks the light. When monitoring the tensile deformation of the sample, the tensile deformation of the sample is monitored by detecting the shadowed area on the sensor 4 where no light is received. This avoids direct contact with the sample, thus preventing thermal expansion differences when the monitoring device is in contact with the sample and ensuring the accuracy of the monitoring results of the stainless steel temperature tensile deformation monitoring device.
