Description

[0002] Rubber bearings, as crucial damping components in bridges, buildings, and other engineering structures, directly impact the safety and durability of these structures due to their mechanical properties. Compressive strength is one of the key mechanical indicators of rubber bearings, and deformation is a vital parameter for measuring compressive strength. Traditional rubber bearing compressive strength tests rely heavily on manual measurement, which has the following drawbacks: low measurement accuracy: manual readings are easily affected by subjective factors, such as visual errors and reading delays, leading to significant errors in the measurement results and failing to meet the requirements of high-precision testing; low efficiency: manual measurement requires repeated operations and data recording, which is time-consuming and labor-intensive, making it difficult to achieve rapid testing of large batches of samples. Utility Model Content

[0003] This application provides an automatic deformation measurement device for test blocks of a compression shearing machine to solve the technical problems of large reading errors in measurement results and slow reading speed in batch testing of traditional rubber bearings, which leads to low measurement efficiency.

The pressure mechanism includes a pressure plate, a first driving member, and a controller. The first driving member can drive the pressure plate to move vertically to compress the rubber support on the placement surface. The controller can control the first driving member to apply pressure to the rubber support according to a set pressure value. The device also includes a deformation measuring mechanism, which includes control software, a deformation measuring component disposed on the pressure plate, a measuring rod of the deformation measuring component, and a second driving member to drive the deformation measuring component to move up and down. The test platform has a measuring platform opposite to the measuring rod. When the pressure plate abuts against the rubber support, the control software controls the measuring rod to contact the measuring platform. The measuring rod moves upward as the pressure plate moves downward. The deformation measuring component can measure the displacement of the measuring rod to determine the deformation of the rubber support. The control software can display the deformation measured by the deformation measuring component.

[0006] The automatic deformation measuring device described in this application also includes the following additional technical features:

[0007] It also includes a second drive unit disposed on the body, the second drive unit being able to drive the deformation measuring component to move in the vertical direction.

[0008] It also includes a receiving platform located outside the pressure table, the deformation measuring component is mounted on the receiving platform, and the output end of the second driving component is connected to the receiving platform via a connecting rod.

[0009] The pressure plate is provided with a first limiting boss, and the first limiting boss has a first limiting hole, through which the connecting rod passes.

[0010] The receiving platform is provided with a second limiting hole, the deformation measuring component is located at the top of the receiving platform, one end of the measuring rod is connected to the deformation measuring component, and the other end passes through the second limiting hole and extends downward.

[0011] It also includes a first limiting member and a second limiting member acting on the receiving platform. The receiving platform has a first limit position and a second limit position for moving up and down relative to the pressure platform. When the receiving platform is in the first limit position, the first limiting member restricts the receiving platform from moving further upward. When the receiving platform is in the second limit position, the second limiting member restricts the receiving platform from moving further downward.

[0012] The first limiting member is constructed as a first limiting shaft located above the receiving platform. When the receiving platform is in the first extreme position, the first limiting shaft abuts against the upper surface of the receiving platform, and / or, a vertically extending limiting plate is provided below the receiving platform, and a vertically extending limiting groove is provided in the limiting plate. The second limiting member is constructed as a second limiting shaft located in the limiting groove. When the receiving platform is in the second extreme position, the second limiting shaft abuts against the top end of the limiting groove.

[0013] The test bench is provided with a second limiting boss, the second limiting boss has a second limiting hole, the bottom of the test bench is provided with a mounting rod, the mounting rod passes through the second limiting hole and can slide up and down along the second limiting hole; it also includes a fixing member, the fixing member can fix the mounting rod to limit the displacement of the mounting rod relative to the second limiting boss.

[0014] The second limiting boss includes two symmetrically arranged irregularly shaped limiting plates. The irregularly shaped limiting plates are provided with oppositely positioned fixing holes. The fixing member passes through the two fixing holes in sequence. The fixing member is provided with a rotating handle. The rotating handle can drive the fixing member to rotate to lock the two irregularly shaped limiting plates.

[0015] The deformation measuring component is a dial indicator or a micrometer, or a measuring instrument with the same function, and the measuring rod is the measuring rod of the measuring instrument. Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0016] 1. In the compression test of the rubber bearing, the rubber bearing is first placed on the test platform. Then, the controller controls the first driving component to move, causing the pressure platform to descend to a position where it contacts the rubber bearing. At this point, the end of the measuring rod contacts the test platform. According to the test requirements, the controller controls the pressure platform to apply different pressure values ​​to the rubber bearing through the first driving component. The rubber bearing will compress under pressure, shortening the distance between the pressure platform and the test platform. The measuring rod will move upward due to the contact action of the test platform, and the deformation measuring component will measure the displacement of the measuring rod. The displacement of the measuring rod is the relative displacement between the pressure platform and the test platform, which is equivalent to the deformation of the rubber bearing. The control software presents this deformation to the operator, allowing the operator to intuitively understand the deformation result. Compared with existing technologies, the device of this application achieves the measurement of the deformation of the rubber bearing through automation, improving measurement accuracy and efficiency, and avoiding errors and inefficiencies caused by manual operation. Therefore, the automatic deformation measuring device for test blocks of the pressure shearing machine provided in this application effectively solves the problems of low accuracy and low efficiency in traditional measurement methods through reasonable structural design and automated control, and has high practical value.

[0017] 2. In a preferred embodiment of this application, by adding a second driving component, the deformation measuring component can move vertically. For rubber supports of different heights, when the pressure table contacts the upper surface of the rubber support, the second driving component controls the movement of the deformation measuring component, and the measuring rod also moves until it contacts the measuring table. The addition of the second driving component allows the deformation measuring component to automatically adjust its position, ensuring the accuracy and consistency of the measurement. Specifically, the second driving component can be a common driving device such as an electric push rod or a cylinder, which drives the deformation measuring component to move precisely vertically by controlling its extension and retraction. The advantage of this design is that it improves the accuracy and efficiency of the measurement by automating the adjustment of the deformation measuring component's position, avoiding errors and inconvenience caused by manual operation. Compared with the prior art, the automatic deformation measuring device provided by this application can achieve higher precision deformation measurement, is suitable for rapid testing of large batches of samples, and significantly improves testing efficiency and accuracy. Preferably, the control software is connected to the second driving component, and the control software can control the second driving component to raise and lower the deformation measuring component.

[0042] like Figures 1 to 5As shown, an automatic deformation measuring device for a test block of a compression shearing machine includes a machine body 1, a test platform 2 on the machine body 1, and a placement surface 21 for placing a rubber support 120. The machine body 1 also includes a pressure mechanism located above the test platform 2. The pressure mechanism includes a pressure plate 3, a first driving member 4, and a controller. The first driving member 4 can drive the pressure plate 3 to move vertically to compress the rubber support 120 on the placement surface 21. The controller can control the first driving member 4 to apply pressure to the rubber support 120 according to a set pressure value. The device also includes deformation measurement. The deformation measurement mechanism includes control software, a deformation measuring component 5 mounted on the pressure table 3, a measuring rod 6 of the deformation measuring component 5, and a second driving component 7 that drives the deformation measuring component 5 to move up and down. The test bench 2 is equipped with a measuring platform 22 that is opposite to the measuring rod 6. When the pressure table 3 abuts against the rubber support, the control software controls the measuring rod 6 to abut against the measuring platform 22. The measuring rod 6 moves upward as the pressure table 3 moves downward. The deformation measuring component 5 can measure the displacement of the measuring rod 6 to obtain the deformation of the rubber support. The control software can display the deformation measured by the deformation measuring component 5.

[0043] During the compression test of the rubber support 120, the rubber support 120 is first placed on the placement surface 21 of the test bench 2. Then, the controller controls the first drive component 4 to move, causing the pressure platform 3 to descend to a state of contact with the rubber support 120. At this time, the end of the measuring rod 6 contacts the test platform 22. According to the test requirements, the controller controls the pressure platform 3 to apply different pressure values ​​to the rubber support 120 through the first drive component 4. The rubber support 120 will undergo a certain amount of compression under pressure, and the distance between the pressure platform 3 and the test bench 2 will shorten. The measuring rod 6 will move upward due to the contact action of the test platform 22. The deformation measuring component 5 will measure the displacement of the measuring rod 6 due to the contact action of the measuring rod 6. The displacement of the measuring rod 6 is the relative displacement between the pressure platform 3 and the test bench 2, which is equivalent to the deformation of the rubber support 120. The control software presents this deformation to the operator's field of vision, allowing the operator to intuitively understand the deformation result. Compared with existing technologies, the device of this application achieves the measurement of the deformation of the rubber support 120° through automation, improving measurement accuracy and efficiency, and avoiding errors and inefficiencies caused by manual operation. Therefore, the automatic deformation measurement device for the test block of the compression shearing machine provided by this application, through reasonable structural design and automated control, effectively solves the problems of low accuracy and low efficiency in traditional measurement methods, and has high practical value.

[0044] It should be noted that the set pressure value mentioned in this application does not refer to a specific value, but can be adapted to different types of rubber bearings 120 and different test stages. Generally, the test of rubber bearings 120 requires graded loading, and the pressure value required for each level of test is also different.

[0045] As a preferred embodiment of this application, such as Figure 1 , Figure 2 As shown, it also includes a second drive member 7 disposed on the body 1, which can drive the deformation measuring member 5 to move in the vertical direction.

[0046] Because the heights of the rubber supports 120 vary, the distance between the pressure platform 3 and the test bench 2 differs when the pressure platform 3 contacts the upper surface of the rubber support 120, resulting in different distances between the end of the measuring rod 6 and the test bench 22. In this embodiment, by adding a second driving component 7, the deformation measuring component 5 can move vertically. For rubber supports 120 of different heights, when the pressure platform 3 contacts the upper surface of the rubber support 120, the second driving component 7 controls the movement of the deformation measuring component 5, and the measuring rod 6 also moves until it contacts the test bench 22. The addition of the second driving component 7 allows the deformation measuring component 5 to automatically adjust its position, ensuring the accuracy and consistency of the measurement. Specifically, the second driving component 7 can be a common driving device such as an electric push rod or a cylinder, which controls its extension and retraction to drive the deformation measuring component 5 to move precisely vertically. The advantage of this design is that by automating the adjustment of the position of the deformation measuring component 5, the accuracy and efficiency of the measurement are improved, avoiding errors and inconveniences caused by manual operation. Compared with existing technologies, the automatic deformation measuring device provided in this application can achieve higher precision deformation measurement, is suitable for rapid testing of large batches of samples, and significantly improves testing efficiency and accuracy. Preferably, the control software is connected to the second drive component 7, and the control software can control the second drive component 7 to drive the deformation measuring component 5 to rise and fall.

[0047] As a preferred embodiment of this implementation, such as Figure 3 , Figure 4 As shown, it also includes a receiving platform 31 located outside the pressure platform 3. The deformation measuring component 5 is mounted on the receiving platform 31, and the output end of the second driving component 7 is connected to the receiving platform 31 via a connecting rod 71. The receiving platform 31 provides a mounting position for the deformation measuring component 5. The second driving component 7 drives the receiving platform 31 to move via the connecting rod 71 to adjust the vertical height of the deformation measuring component 5, making the vertical movement of the deformation measuring component 5 smoother and achieving precise control of the measurement process. The installation position and movement mode of the deformation measuring component 5 help improve the stability and accuracy of the measurement and avoid measurement errors caused by the unstable position of the deformation measuring component 5.

[0048] Furthermore, the design of the receiving platform 31 can take different forms. For example, the receiving platform 31 can be designed as an independent frame or integrally formed with the pressure platform 3. The connection method of the connecting rod 71 can also be adjusted according to specific needs. For example, the connecting rod 71 can be connected to the receiving platform 31 by thread or snap-fit ​​to ensure the stability and reliability of the connection.

[0049] As a preferred example in this embodiment, such as Figure 2 As shown, the pressure table 3 is provided with a first limiting boss 32, and the first limiting boss 32 has a first limiting hole, through which the connecting rod 71 passes. By providing the first limiting boss 32 on the pressure table 3 and having the first limiting hole on the first limiting boss 32, and through which the connecting rod 71 passes, the connecting rod 71 can move freely within the first limiting hole, thereby effectively limiting and guiding the movement of the connecting rod 71. The purpose of this design is to ensure that the deformation measuring component 5 can maintain a stable movement trajectory during the pressure application process, and to avoid affecting the measurement accuracy due to the offset of the connecting rod 71.

[0050] As another preferred example under this embodiment, such as Figure 4 As shown, a second limiting hole is provided on the receiving platform 31. The deformation measuring component 5 is located at the top of the receiving platform 31. One end of the measuring rod 6 is connected to the deformation measuring component 5, and the other end passes through the second limiting hole and extends downward. By setting the second limiting hole, the measuring rod 6 can move accurately in the vertical direction, thereby ensuring the accuracy of the measurement. The deformation measuring component 5 is located at the top of the receiving platform 31, and one end of the measuring rod 6 is connected to the deformation measuring component 5. The other end passes through the second limiting hole and extends downward. This design allows the measuring rod 6 to maintain a stable vertical movement trajectory during the measurement process, avoiding measurement errors caused by the tilting of the measuring rod 6.

[0051] As a preferred embodiment in this example, the device further includes a first limiting member and a second limiting member acting on the receiving platform 31. The receiving platform 31 has a first limit position and a second limit position for vertical movement relative to the pressure platform 3. When the receiving platform 31 is at the first limit position, the first limiting member restricts the further upward movement of the receiving platform 31; when the receiving platform 31 is at the second limit position, the second limiting member restricts the further downward movement of the receiving platform 31. By setting the first limiting member and the second limiting member, the movement range of the receiving platform 31 can be effectively limited, thereby ensuring the stability and accuracy of the measurement process. Specifically, when the receiving platform 31 is at the first limit position, the first limiting member restricts its further upward movement to prevent the receiving platform 31 from exceeding the set upper limit position; when the receiving platform 31 is at the second limit position, the second limiting member restricts its further downward movement to prevent the receiving platform 31 from exceeding the set lower limit position. Thus, the entire measuring device can perform stable deformation measurement within a predetermined range.

[0052] Furthermore, such as Figure 4As shown, the first limiting member is a first limiting shaft 8 located above the receiving platform 31. When the receiving platform 31 is at its first extreme position, the first limiting shaft 8 abuts against the upper surface of the receiving platform 31. A vertically extending limiting plate 10 is provided below the receiving platform 31, and a vertically extending limiting groove 101 is formed in the limiting plate 10. The second limiting member is a second limiting shaft 9 located within the limiting groove 101. When the receiving platform 31 is at its second extreme position, the second limiting shaft 9 abuts against the top of the limiting groove 101. By setting the first and second limiting members, the precise positioning of the receiving platform 31 at its upper and lower extreme positions is ensured. The first limiting member is the first limiting shaft 8 located above the receiving platform 31. When the receiving platform 31 reaches its first extreme position, the first limiting shaft 8 abuts against the upper surface of the receiving platform 31, thereby limiting the further upward movement of the receiving platform 31. Furthermore, a vertically extending limiting plate 10 is provided below the receiving platform 31, and a vertically extending limiting groove 101 is formed within the limiting plate 10. The second limiting element is a second limiting shaft 9 located within the limiting groove 101. When the receiving platform 31 reaches the second limit position, the second limiting shaft 9 abuts against the top of the limiting groove 101, thereby limiting the further downward movement of the receiving platform 31. Through the above settings, this application achieves precise control over the position of the receiving platform 31, ensuring the stability of the receiving platform 31 and the accuracy of the measurement results during the measurement process. Compared with the prior art, the technical solution of this application can significantly improve the accuracy and efficiency of measuring the deformation of the rubber support 120, reduce human error, and is suitable for rapid testing of large batches of samples.

[0053] Preferably, the application table is provided with a working plate, and a horizontally extending stop groove is opened in the working plate. The projection of the stop groove in the vertical direction falls on the receiving table 31, and the projection falls outside the receiving table 31. The first limiting shaft 8 can move in the stop groove.

[0054] As a preferred embodiment of this application, such as Figure 5As shown, the test bench 2 is provided with a second limiting boss 23, which has a second limiting hole. The bottom of the measuring platform 22 is provided with a mounting rod 221, which passes through the second limiting hole and can slide up and down along it. A fixing member is also included to fix the mounting rod 221 and limit its displacement relative to the second limiting boss 23. By providing a second limiting boss 23 with a second limiting hole on the test bench 2, and a mounting rod 221 at the bottom of the measuring platform 22 that passes through the second limiting hole and can slide up and down along it, and by including a fixing member to fix the mounting rod 221 and limit its displacement relative to the second limiting boss 23, this design ensures the stability of the measuring platform 22 and the accuracy of the measurement process, thereby improving measurement precision. Specifically, the design of the second limiting boss 23 allows the mounting rod 221 to slide up and down within the second limiting hole, thus facilitating the installation and adjustment of the measuring platform 22. The installation of fixing components further ensures the stability of the measuring platform 22 during the measurement process, avoiding measurement errors caused by displacement of the measuring platform 22. This design not only improves measurement accuracy but also simplifies the operation of the measuring device and increases work efficiency.

[0055] As a preferred embodiment of this implementation, such as Figure 5 As shown, the second limiting boss 23 includes two symmetrically arranged irregularly shaped limiting plates 231. The irregularly shaped limiting plates 231 have corresponding fixing holes. A fixing member passes through the two fixing holes sequentially. A rotating handle 110 is provided outside the fixing member. The rotating handle 110 can drive the fixing member to rotate, thereby locking the two irregularly shaped limiting plates 231. In this application, the design of the second limiting boss 23 is achieved through two symmetrically arranged irregularly shaped limiting plates 231. These limiting plates 10 have corresponding fixing holes, and the fixing member passes through these fixing holes sequentially. Operation is performed by rotating the handle 110. Rotating the handle 110 can drive the fixing member to rotate, thereby locking the irregularly shaped limiting plates 231. This design allows the limiting plates 10 to be more stably fixed in the required position, ensuring accuracy and reliability during the measurement process. The design of the fixing member and the combined use of the rotating handle 110 allow the operator to easily adjust and fix the position of the limiting plates 10, thus ensuring the adaptability of the measuring device under different test conditions. In this way, displacement of the limiting plate 10 during the measurement process can be effectively avoided, thereby improving the accuracy of the measurement results.

[0056] In a preferred embodiment of this application, the deformation measuring component 5 is a dial indicator or a micrometer or a measuring instrument with the same function, and the measuring rod is the measuring rod of the measuring instrument. The dial indicator or micrometer, as the deformation measuring component 5, can provide high-precision displacement measurement. The deformation of the rubber support 120 can be accurately determined by the displacement of the measuring rod. Compared with traditional manual measurement methods, the use of the dial indicator or micrometer greatly improves the accuracy and reliability of the measurement, avoiding errors in manual readings and operational delays. Preferably, the dial indicator or micrometer can be mounted on the pressure table 3 using a fixing device to ensure the stability and accuracy of the measurement. Under the limiting action of the measuring table 22, the measuring rod of the dial indicator or micrometer moves with the pressure table 3, generating displacement. The dial indicator or micrometer can accurately record this displacement and display it through the controller.
