Description

Technical Field

[0001] This utility model relates to the field of tensile testing technology, and in particular to a tensile rate calibration device. Background Technology

[0002] A tensile rate calibration device is a device used to calibrate the tensile rate in a material tensile test. It typically calculates the actual tensile rate by accurately measuring the displacement and time during the tensile process. It can be used in conjunction with a tensile testing machine to calibrate and adjust the machine's tensile rate.

[0003] However, the tensile rate calibration device in the relevant technology still has shortcomings. When calibrating and adjusting the tensile rate of the testing machine, the tensile rate calibration device needs to be installed on the testing machine for use. However, due to the different sizes of the testing machines, the connection hole positions for installing the tensile rate calibration device are different, making it impossible to install and fix the tensile rate calibration device on testing machines of different sizes, reducing the practicality of the tensile rate calibration device. Therefore, we proposed a tensile rate calibration device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by proposing a tensile rate calibration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tensile rate calibration device includes a calibration device housing and four mounting plates for fixing to a tensile testing machine. The calibration device housing houses a processor and a data processing module. A displacement sensor and a timer for tensile rate calibration are fixedly connected to the top of the calibration device housing. A display screen and operation buttons are located on the front of the calibration device housing. The data processing module, displacement sensor, timer, display screen, and operation buttons are all electrically connected to the processor. Support plates are fixedly connected to both sides of the calibration device housing, and an adjustment mechanism is provided between the support plate and the mounting plate on the same side.

[0007] As a preferred embodiment of this invention, ventilation filters are fixedly connected to both sides of the calibration device housing.

[0008] As a preferred embodiment of this invention, the calibration device housing has three data connection ports on one side, and all three data connection ports are electrically connected to the processor.

[0009] In a preferred embodiment of this utility model, the adjusting mechanism includes a movable plate and a slider fixedly connected to the bottom of the movable plate. The mounting plate is fixedly connected to the bottom of the slider. The top of the support plate has multiple slots and a rectangular opening. The slider is slidably fitted into the rectangular opening. The movable plate has two cavities. A compression spring is fixedly connected to the top inner wall of the cavity. A lifting plate is fixedly connected to the bottom of the compression spring. A locking block is fixedly connected to the bottom of the lifting plate. The two locking blocks are movably engaged in the corresponding slots. A pull rod is fixedly connected to the top of each of the two lifting plates.

[0010] In a preferred embodiment of this utility model, the top ends of the two pull rods are fixedly connected to the same pull plate, and a locking assembly is provided between the pull plate and the moving plate. The locking assembly includes a fixed seat fixedly connected to the bottom of the pull plate and a rotating shaft rotatably connected to the top of the moving plate. Locking blocks are fixedly connected to both sides of the rotating shaft. Two limiting grooves are opened at the bottom of the fixed seat, and arc-shaped grooves are opened on the top inner walls of the two limiting grooves. The arc-shaped grooves cooperate with the locking blocks.

[0011] In a preferred embodiment of this invention, the rotating shaft is movably sleeved within the fixed base, and the locking block is slidably sleeved within the limiting groove.

[0012] As a preferred embodiment of this invention, the two lifting plates are slidably sleeved in the corresponding cavities.

[0013] As a preferred embodiment of this invention, the two compression springs are respectively sleeved on the outer side of the corresponding pull rod.

[0014] In this utility model, the tensile rate calibration device is installed correctly on the tensile testing machine, and the connection between each part is stable and reliable. The displacement sensor and timer on the tensile testing machine and the calibration device are started to conduct a tensile test. The calibration device will measure the displacement and time in real time and calculate the actual tensile rate. According to the calibration result, the tensile rate of the tensile testing machine is adjusted, and then the calibration is performed again to verify the accuracy of the adjustment.

[0015] In this invention, the tensile rate calibration device, when connected and installed with tensile testing machines of different specifications, rotates the shaft, causing the shaft to drive two locking blocks to rotate within the arc-shaped groove. This allows the locking blocks to align with the limiting groove, thus preventing the locking blocks from limiting and fixing the pull plate. Pulling the pull plate upwards moves the two pull rods, two lifting plates, and two locking blocks upwards, disengaging them from the locking groove. This prevents the moving plate, slider, and mounting plate from being fixed. Pulling the moving plate and mounting plate back and forth adjusts the front and back position of the mounting plate, allowing the mounting plate to be adjusted. Align the mounting hole with the connecting hole on the tensile testing machine, then release the pull plate. Under the elastic force of the compression spring, the pull plate and the two locking blocks move down and engage in the corresponding slots, thereby locking the mounting plate. To ensure the stability of the installation, when the pull plate moves down to reset, the locking block slides into the limiting slot and the arc-shaped slot. Finally, rotate the shaft to make the locking block screw into the arc-shaped slot, thereby making the locking block and the limiting slot misaligned, thus achieving the purpose of limiting and fixing the pull plate, preventing the pull plate from moving upward, and improving the stability of the installation of the mounting plate and calibration device.

[0016] This utility model has a reasonable structural design. Through the adjustment mechanism, the position of the four mounting plates can be adjusted so that the mounting holes on the mounting plates are aligned with the connection holes on the tensile testing machine, which improves the convenience and efficiency of the calibration device installation and makes the performance better. At the same time, the setting of the locking component facilitates the effective locking of the pull plate and the locking block, which greatly improves the stability of the installation of the mounting plate and the calibration device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 The tensile rate calibration device includes a calibration device housing 1 and four mounting plates 2 for fixing to a tensile testing machine. A processor 18 and a data processing module 17 are housed inside the calibration device housing 1. A displacement sensor 11 and a timer 12 for tensile rate calibration are fixedly connected to the top of the calibration device housing 1. A display screen 13 and operation buttons 14 are located on the front side of the calibration device housing 1. The data processing module 17, displacement sensor 11, timer 12, display screen 13, and operation buttons 14 are all electrically connected to the processor 18. Support plates 3 are fixedly connected to both sides of the calibration device housing 1. An adjustment mechanism 4 is provided between the support plate 3 and the mounting plates 2 on the same side. Ventilation filters 15 are fixedly connected to both sides of the calibration device housing 1. Three data connection ports 16 are opened on one side of the calibration device housing 1, and all three data connection ports 16 are electrically connected to the processor 18.

[0026] The above scheme involves correctly installing the calibration device housing 1 onto the tensile testing machine, ensuring stable and reliable connections between all parts, starting the displacement sensor (which can be a grating ruler, laser displacement sensor, etc.) and timer on the tensile testing machine and calibration device, and conducting a tensile test. The calibration device measures displacement and time in real time and calculates the actual tensile rate. Based on the calibration results, the tensile rate of the tensile testing machine is adjusted, and then recalibrated to verify the accuracy of the adjustment. The data processing module receives displacement and time data, performs calculations and analysis to determine the actual tensile rate. This unit can be computer software or dedicated electronic equipment. Finally, the converted tensile rate is fed back to the processor 18, which displays it on the display screen 13. The data connection port 16 allows the calibration device to connect to other devices.

[0027] Furthermore, refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The adjusting mechanism 4 includes a movable plate 401 and a slider 403 fixedly connected to the bottom of the movable plate 401. A mounting plate 2 is fixedly connected to the bottom of the slider 403. The top of the support plate 3 has multiple slots 404 and a rectangular opening 402. The slider 403 is slidably fitted into the rectangular opening 402. The movable plate 401 has two cavities 406. A compression spring 408 is fixedly connected to the top inner wall of each cavity 406. A lifting plate 407 is fixedly connected to the bottom of the compression spring 408. A locking block 405 is fixedly connected to the bottom of the lifting plate 407. The two locking blocks 405 are movably engaged in the corresponding slots 404. Inside, the tops of the two lifting plates 407 are fixedly connected to pull rods 409, and the tops of the two pull rods 409 are fixedly connected to the same pull plate 410. A locking assembly is provided between the pull plate 410 and the moving plate 401. The locking assembly includes a fixed seat 412 fixedly connected to the bottom of the pull plate 410 and a rotating shaft 411 rotatably connected to the top of the moving plate 401. Locking blocks 415 are fixedly connected to both sides of the rotating shaft 411. Two limiting grooves 413 are opened at the bottom of the fixed seat 412. Arc grooves 414 are opened on the inner top of the two limiting grooves 413. The arc grooves 414 cooperate with the locking blocks 415.

[0028] Using the above scheme: When connecting and installing with tensile testing machines of different specifications, rotating the shaft 411 causes the two locking blocks 415 to rotate within the arc-shaped groove 414, so that the locking blocks 415 are aligned with the limiting groove 413. Therefore, the locking blocks 415 do not limit or fix the pull plate 410. Pulling the pull plate 410, the two pull rods 409, the two lifting plates 407, and the two locking blocks 405 upwards moves them out of the locking groove 404, thus not fixing the moving plate 401, the slider 403, and the mounting plate 2. Pulling the moving plate 401 and the mounting plate 2 back and forth adjusts the front and back position of the mounting plate 2, so that the mounting holes on the mounting plate 2 are aligned with the tensile testing machine. The connecting holes on the testing machine are aligned, and then the pull plate 410 is released. Under the elastic force of the compression spring 408, the pull plate 410 and the two locking blocks 405 move down and lock into the corresponding locking grooves 404, thereby locking the mounting plate 2. In order to ensure the stability of the installation, when the pull plate 410 moves down to reset, the locking block 415 slides into the limiting groove 413 and the arc groove 414. Finally, the rotating shaft 411 is rotated so that the locking block 415 is screwed into the arc groove 414, thereby making the locking block 415 and the limiting groove 413 misaligned, thereby achieving the purpose of limiting and fixing the pull plate 410, so that the pull plate 410 cannot move upward, improving the stability of the installation of the mounting plate 2 and the calibration device.

[0029] Furthermore, the rotating shaft 411 is movably sleeved in the fixed seat 412, the locking block 415 is slidably sleeved in the limiting groove 413, the two lifting plates 407 are respectively slidably sleeved in the corresponding cavities 406, and the two compression springs 408 are respectively sleeved on the outside of the corresponding pull rods 409, which is conducive to guiding and limiting the rotating shaft 411, locking block 415, lifting plate 407 and compression spring 408, making their movement more stable and smooth.

[0030] In this invention, during use, the calibration device housing 1 is correctly installed on the tensile testing machine, ensuring stable and reliable connections between all parts. The displacement sensor (which can be a grating ruler, laser displacement sensor, etc.) and timer on the tensile testing machine and calibration device are started to conduct a tensile test. The calibration device measures displacement and time in real time and calculates the actual tensile rate. Based on the calibration results, the tensile rate of the tensile testing machine is adjusted, and then recalibrated to verify the accuracy of the adjustment. The data processing module can receive displacement and time data, perform calculations and analysis to determine the actual tensile rate. This unit can be computer software or dedicated electronic equipment. Finally, the converted tensile rate is fed back to the processor 18, which displays it on the display screen 13. The data connection port 16 allows the calibration device to connect to other devices.

[0031] When connecting and installing with tensile testing machines of different specifications, rotating the shaft 411 causes the two locking blocks 415 to rotate within the arc-shaped groove 414, so that the locking blocks 415 are aligned with the limiting groove 413. This prevents the locking blocks 415 from limiting and fixing the pull plate 410. Pulling the pull plate 410, the two pull rods 409, the two lifting plates 407, and the two locking blocks 405 upwards causes them to disengage from the locking groove 404, thus preventing the moving plate 401, the slider 403, and the mounting plate 2 from being fixed. Pulling the moving plate 401 and the mounting plate 2 back and forth adjusts the position of the mounting plate 2, allowing the mounting holes on the mounting plate 2 to align with the tensile testing machine. Align the connecting holes on the plate, then release the pull plate 410. Under the elastic force of the compression spring 408, the pull plate 410 and the two locking blocks 405 move down and engage in the corresponding slots 404, thereby locking the mounting plate 2. To ensure the stability of the installation, when the pull plate 410 moves down to reset, the locking block 415 slides into the limiting groove 413 and the arc groove 414. Finally, by rotating the rotating shaft 411, the locking block 415 is screwed into the arc groove 414, thereby causing the locking block 415 to be misaligned with the limiting groove 413, thus achieving the purpose of limiting and fixing the pull plate 410, preventing the pull plate 410 from moving upward, and improving the stability of the installation of the mounting plate 2 and the calibration device.
