[0003] In existing technologies, the bending stiffness testing device for rubber composite materials mainly consists of a pressure sensor, a servo electric actuator, a probe, and a linear displacement sensor. The linear displacement sensor and the servo electric actuator are mounted and fixed on the frame. During testing, the test piece is fixed by a fixture, and the servo controller pushes the support and the probe above to move. The movement of the probe applies pressure to the test piece, causing the middle part of the test piece to flex and deform under the action of the probe. The pressure sensor measures the pressure value, and the linear displacement sensor measures the position of the probe. The pressure required for the test piece to achieve the specified flexural deformation is converted into the bending stiffness of the test piece.

However, the existing testing equipment is not convenient for adjusting the position of the probe, making it inconvenient for staff to test different areas of the rubber parts.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] Specific implementation examples are given below.
[0024] Please see Figure 1-2 As shown, a rubber composite bending stiffness testing device includes a frame 11 and a probe 15. A testing assembly for testing bending stiffness is mounted on the frame 11, and a fixing clamp is mounted on the top of the frame 11. A support 12 is mounted on the testing assembly, and a base 16 is fixedly connected to the top of the support 12. A movable seat 14 is slidably connected inside the base 16, and a first screw 13 is rotatably connected to the middle of the base 16. The first screw 13 passes through the movable seat 14 and is threadedly connected to it. The probe 15 is detachably mounted on the top of the movable seat 14. The testing assembly includes a servo electric actuator 21, a linear displacement sensor 23, and a pressure sensor 22. The servo electric actuator 21 is fixedly connected to the top of the frame 11, the pressure sensor 22 is installed between the output end of the servo electric actuator 21 and the support 12, and the linear displacement sensor 23 is installed on the side of the support 12 and fixedly connected to the frame 11.
[0025] During the test, the rubber composite test piece is fixed with a fixture. The servo controller drives the support 12 and the probe 15 above to move. The movement of the probe 15 applies pressure to the test piece. The middle part of the test piece flexes and deforms under the action of the probe 15. The pressure value is measured by the pressure sensor 22 and the position of the probe 15 is measured by the linear displacement sensor 23. The pressure required for the test piece to reach the specified flexural deformation is converted into the bending stiffness of the test piece. When different parts need to be tested, the operator can rotate the first screw 13. The rotation of the first screw 13 will cause the base 16 and the probe 15 to move under the action of the thread, thereby adjusting the position of the probe 15. This makes it convenient for the operator to test the bending stiffness of different areas of the test piece, thus making it convenient for the operator to use.
[0026] Furthermore, such as Figure 3-4 As shown, the fixing fixture includes a fixing base 31, two first clamping seats 34 are fixedly connected to the top of the fixing base 31, an electric cylinder 32 is fixedly connected to the fixing base 31, a support plate 33 is fixedly connected to the output end of the electric cylinder 32, and a pair of second clamping seats 35 are fixedly connected to the top of the support plate 33. The second clamping seats 35 are located on the side of the first clamping seats 34. In use, the electric cylinder 32 pulls the support plate 33, thereby causing the second clamping seats 35 on the support plate 33 to move towards the first clamping seats 34. The first clamping seats 34 and the second clamping seats 35 clamp and fix the rubber composite material test piece, thereby improving the stability during the test.
[0027] Furthermore, such as Figure 3-4 As shown, the two second clamps 35 have through grooves inside, and pulleys 4 are rotatably connected in the through grooves. In use, the rubber composite material test piece can be easily pulled and moved by relying on the through grooves and the pulleys 4 rotatably connected inside. This makes it convenient for the staff to adjust the position of the rubber composite material test piece during testing. When testing is required, the pulleys 4 can be used to squeeze and press it against the first clamp 34 to fix it.
[0028] Furthermore, such as Figure 1 and 3 As shown, a second screw 51 is rotatably connected to the first clamp 34, and a top seat 52 is threadedly connected to the second screw 51. The top seat 52 is located between the two first clamps 34. In use, the second screw 51 is rotated, and the thread on the second screw 51 drives the top seat 52 to move, thereby adjusting the position of the top seat 52. The top seat 52 is used to support the rubber composite material from the rear. When testing different areas of the rubber composite material, the support part of the rubber composite material can be adjusted according to the requirements.
[0029] Furthermore, such as Figure 1As shown, a first slide rail 61 is fixedly connected to the top of the fixed base 31, and the top seat 52 is slidably connected to the first slide rail 61. A second slide rail 62 is fixedly connected to the top of the frame 11, and the second slide rail 62 is slidably connected to the support 12. A guide rod 63 is fixedly connected to the base 16, and the movable seat 14 is slidably connected to the guide rod 63. In use, the first slide rail 61, the second slide rail 62, and the guide rod 63 are used to guide the movement of the top seat 52, the probe 15, and the support 12, respectively, thereby improving the stability of movement and thus facilitating the improvement of testing accuracy.
[0030] Furthermore, such as Figure 3 As shown, a handwheel 7 is fixedly connected to the end of both the first screw 13 and the second screw 51. In use, the first screw 13 and the second screw 51 can be easily rotated by the handwheel 7, which makes it convenient for the operator to operate and control the first screw 13 and the second screw 51.
[0031] Working principle: During the test, the rubber composite test piece is fixed by a clamp. The servo controller drives the support 12 and the probe 15 above to move. The movement of the probe 15 applies pressure to the test piece. The middle part of the test piece flexes and deforms under the action of the probe 15. The pressure value is measured by the pressure sensor 22 and the position of the probe 15 is measured by the linear displacement sensor 23. The pressure required for the test piece to reach the specified flexural deformation is converted into the bending stiffness of the test piece. When different parts need to be tested, the operator can rotate the first screw 13. The rotation of the first screw 13 causes the base 16 and the probe 15 to move under the action of the thread, thereby adjusting the position of the probe 15. This makes it convenient for the operator to test the bending stiffness of different areas of the test piece. This makes it convenient for the operator to use. The electric cylinder 32 pulls the support plate 33, thereby moving the second clamp 35 on the support plate 33 towards the first clamp 34. The first clamp 34 and the second clamp 35 clamp and fix the rubber composite material test piece, thereby improving the stability during the test. The rubber composite material test piece can be easily pulled and moved using the through groove and the internally rotating pulley 4, allowing staff to easily adjust its position during testing. When testing is required, the pulley 4 presses the test piece against the first clamp 34 for secure fixing. The second screw 51 rotates, and the thread on the second screw 51 drives the top seat 52 to move, thus adjusting its position. The top seat 52 supports the rubber composite material from the rear. When testing different areas of the rubber composite material, the support position can be adjusted as needed. During use, the first slide rail 61, the second slide rail 62, and the guide rod 63 guide the movement of the top seat 52, the probe 15, and the support 12, respectively, improving the stability of movement and thus enhancing the accuracy of the test.
