[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] This utility model embodiment provides a rubber deformation testing mechanism, such as... Figure 1-4 As shown, the rubber deformation testing mechanism includes: a frame 1 and two tension seats 2 and two compression seats 4 symmetrically arranged on the frame 1; a moving mechanism mounted on the frame 1, the tension seats 2 and the compression seats 4 for moving the tension seats 2 and the compression seats 4, wherein the moving mechanism is used to move one of the tension seats 2 so that the two tension seats 2 move away from each other to perform a tensile deformation test on the rubber, and the moving mechanism is used to move one of the compression seats 4 so that the two compression seats 4 move closer to each other to perform a compression deformation test on the rubber.

[0019] In this embodiment, firstly, one side of the device is provided with an OMRON model. The controller of the E5CC-QX2ASM-800 allows for the control and operation of the entire device. The controller's working principle is based on existing technology and will not be elaborated upon here. One tension seat 2 is equipped with a tension sensor 3 to monitor the tensile force applied to the rubber, and one compression seat 4 is equipped with a pressure sensor 5 to monitor the compressive force applied to the rubber. During tensile deformation testing, the rubber is fixed at both ends to the two tension seats 2. The controller activates a moving mechanism to move one of the tension seats 2 upwards, thus stretching the clamped rubber and applying tensile force to simulate a tensile condition. At this time, the HBMU9B tension sensor 3 monitors the magnitude of the tensile force in real time, thereby acquiring deformation data of the rubber under different tensile forces, and thus monitoring the deformation of the rubber under different tensile forces. Simultaneously, when monitoring the compression deformation of the rubber, the rubber sample is placed on the lower compression seat 4. Then, the controller activates a moving mechanism to move one of the compression seats 4 downwards, thereby applying pressure to the rubber to simulate a compression condition. The pressure sensor 5 is activated by the HBM... The U9C's pressure sensor 5 monitors the pressure in real time, thereby obtaining deformation data of the rubber under different pressure conditions. This allows for monitoring of the rubber's deformation under varying pressures, enabling tensile and compressive deformation tests. This significantly expands the testing capabilities, meeting the needs for monitoring different forms of rubber deformation. It has a wider range of applications and can more comprehensively and accurately detect the quality of rubber. The entire device can monitor various forms of rubber deformation, better meeting the requirements for rubber deformation monitoring and offering greater flexibility in use.

[0020] In a further preferred embodiment of the present invention, the moving mechanism includes: a first telescopic rod 6 fixedly installed on the frame 1; and a mounting plate 7 fixedly installed on the output shaft of the first telescopic rod 6, wherein the mounting plate 7 is fixedly connected to one of the tension seats 2 and the compression seats 4.

[0021] In this embodiment, when using the moving mechanism to perform a tensile deformation test on the rubber, the controller activates the first telescopic rod 6, whose output shaft drives the mounting plate 7 upward. Since the mounting plate 7 is fixedly connected to one of the tension seats 2, it drives the tension seat 2 upward, applying tension to the rubber fixed on the tension seat 2 to simulate a tensile condition. At the same time, the tension sensor 3 installed on the tension seat 2 monitors the magnitude of the tension in real time to obtain the deformation data of the rubber during the tensile process. If a compression test is to be performed, the first telescopic rod 6 drives the mounting plate 7 downward, and the mounting plate 7 drives the compression seat 4 fixedly connected to it downward, applying pressure to the rubber placed on the compression seat 4 to simulate a compression condition. At this time, the pressure sensor 5 on the compression seat 4 monitors the magnitude of the pressure in real time, thereby obtaining the deformation data of the rubber during the compression process. Different forms of deformation monitoring of the rubber can be performed, better meeting the needs of rubber deformation monitoring, and the application is more flexible.

[0022] In a further preferred embodiment of this utility model, the frame 1 is provided with an adjustment mechanism for adjusting the usage position of one of the tension seats 2. The adjustment mechanism includes: a second telescopic rod 9 disposed on the frame 1, the frame 1 having an installation groove for installing the second telescopic rod 9, the second telescopic rod 9 being located in the installation groove; and a placement plate 10 fixedly installed at the bottom of the tension seat 2, the placement plate 10 being fixedly connected to the output shaft of the second telescopic rod 9.

[0023] In this embodiment, when the rubber is subjected to compression deformation test, the controller activates the second telescopic rod 9 to move the lower tension seat 2 downward, thereby avoiding the two tension seats 2 from touching when the two compression seats 4 are squeezed relative to each other, thus ensuring the safety of the rubber test.

[0024] In a further preferred embodiment of the present invention, each of the two tension seats 2 is provided with a fixing mechanism for fixing the end of the rubber. The fixing mechanism includes: a placement frame 11 fixedly installed on the tension seat 2, and a bidirectional lead screw 12 rotatably installed on the placement frame 11 via a damping shaft; two connecting blocks 13 threaded onto the bidirectional lead screw 12, and clamping blocks 14 for clamping and fixing the rubber are fixedly installed on each of the two connecting blocks 13.

[0025] In this embodiment, when performing a tensile deformation test on the rubber, the controller first activates the moving mechanism based on the length of the rubber to move the upper tension seat 2 down to a certain position, placing the end of the rubber between the two clamping blocks 14. The operator applies force to rotate the bidirectional lead screw 12. A limit rod is fixedly installed on the placement frame 11. The limit rod and two connecting blocks 13 are slidably connected, which limits the two connecting blocks 13. This allows the bidirectional lead screw 12 to stably drive the two connecting blocks 13 to move relative to each other, thereby driving the two clamping blocks 14 to move relative to each other and clamp the end of the rubber. After clamping and fixing one end of the rubber, the fixing mechanism on the other tension seat 2 is operated in the same way to clamp the other end of the rubber, thereby fixing the rubber and then performing the tensile deformation test on the rubber.

[0026] In a further preferred embodiment of the present invention, the clamping block 14 is provided with a plurality of spikes 15, which are evenly distributed on the clamping block 14, and the spikes 15 are used to clamp the end of the rubber.

[0027] In this embodiment, when the clamping block 14 clamps the rubber, the spikes 15 will come into contact with the rubber to form a mechanical interlocking effect, which greatly increases the force between the clamping block 14 and the rubber, significantly improves the firmness of the fixation, and effectively prevents the rubber from slipping off the clamping block 14 due to the large tensile force during the test, thus ensuring the stability of the test process and the accuracy of the test data.

[0028] In a further preferred embodiment of the present invention, slide rods 16 are symmetrically fixedly installed in the mounting groove, and slide rods 16 are slidably connected to the placement plate 10. The slide rods 16 are used to limit the movement of the placement plate 10.

[0029] In this embodiment, when adjusting the position of one of the tension seats 2, the second telescopic rod 9 is controlled to extend and retract, causing the placement plate 10 fixedly connected to it to move, thereby causing the tension seat 2 to move accordingly. During the movement of the placement plate 10, the placement plate 10 will move linearly along the axis of the slide rod 16. The slide rod 16 plays a precise guiding role in the movement of the placement plate 10, ensuring that the placement plate 10 can only move linearly along the axis of the slide rod 16, thus avoiding instability such as offset, shaking or rotation of the placement plate 10 during the movement.

[0030] In a further preferred embodiment of the present invention, the frame 1 is provided with a guide mechanism for guiding the movement of the mounting plate 7. The guide mechanism includes: a guide block 17 fixedly mounted on the mounting plate 7; and a guide rod 18 fixedly mounted on the frame 1, wherein the guide rod 18 and the guide block 17 are slidably connected.

[0031] In this embodiment, during the rubber deformation test, the mounting plate 7 is moved by a moving mechanism. During the movement of the mounting plate 7, the guide block 17 fixed on it slides along the guide rod 18 fixed on the frame 1. The sliding connection between the guide rod 18 and the guide block 17 provides precise guidance for the movement of the mounting plate 7, ensuring that the mounting plate 7 can only move in a straight line along the axial direction of the guide rod 18. This effectively avoids the mounting plate 7 from deviating, tilting, or shaking during the movement. This ensures that the tension seat 2 or compression seat 4 connected to the mounting plate 7 can move accurately according to the preset direction and path, ensuring that the direction of the tension or pressure on the rubber during the test is accurate, and greatly improving the accuracy and reliability of the test results.

[0032] In a further preferred embodiment of the present invention, transparent glass doors are symmetrically hinged on the frame 1. The transparent glass doors are used to protect the rubber during deformation testing, and one of the compression seats 4 is provided with a placement groove for placing the rubber sample.

[0033] In this embodiment, the transparent glass door plays an important protective role during the testing process. On the one hand, it can effectively prevent the rubber sample from breaking or splashing and causing injury to the operator during the testing process, thus ensuring the personal safety of the operator. On the other hand, the glass door can block external debris from entering the testing area, preventing debris from interfering with the testing process or damaging the testing equipment, thereby improving the safety of the testing process.

[0034] In summary, compared with related technologies, this device can monitor rubber deformation in different ways, better meeting the needs of rubber deformation monitoring and offering greater flexibility in use.

[0035] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
