Description

Technical Field

[0001] This utility model relates to the field of sealing component testing technology, and in particular to a sealing component compression permanent deformation testing machine. Background Technology

[0002] As a crucial component for preventing media leakage and the intrusion of external impurities, the performance of seals directly affects the normal operation and safety of equipment. Compression set testing machines provide important data for evaluating the sealing performance, material durability, optimizing product design, and ensuring compliance with industry standards by conducting compression set tests on seals.

[0003] Existing seal compression set testing machines typically use high-strength metal materials to ensure frame stability during testing. However, they cannot limit and fix the seals during testing, causing the seals to shift and reducing the accuracy of subsequent test data. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sealing component compression set testing machine, which aims to improve the problem that existing sealing component compression set testing machines cannot limit and fix the sealing component during testing, resulting in reduced accuracy of subsequent test data.

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

[0006] A compression set testing machine for seals includes a machine body, a test platform fixedly connected to the upper surface of the machine body, a motor inside the test platform, a cross plate connected to the output end of the motor, a transmission assembly inside the cross plate, a connecting column two rotatably connected to the outer wall of the transmission assembly, a clamping assembly at the top of the connecting column two, and a support frame slidably connected to the outer wall of the connecting column two.

[0007] Preferably, the transmission assembly includes a first connecting column, the bottom end of which is fixedly connected to the inside of the cross plate, and the top end of which is rotatably connected to a transmission plate, the inside of which is rotatably connected to the outer wall of the second connecting column.

[0008] Preferably, the clamping assembly includes a fixing plate, the top end of the second connecting column is fixedly connected to the lower surface of the fixing plate, and the clamping plate is attached to the outer wall of the fixing plate.

[0009] Preferably, the outer wall of the fixing plate is fixedly connected to a housing, the housing is provided with a sliding component, the outer wall of the sliding component is provided with a spring, the outer wall of the spring is provided inside the housing, and the outer wall of the sliding component is slidably connected to the inside of the clamping plate.

[0010] Preferably, the sliding assembly includes a sliding column, the outer wall of which is slidably connected to the inside of the housing, a connecting column three is fixedly connected to the outer wall of the sliding column, the outer wall of the connecting column three is slidably connected to the inside of the housing, the outer wall of the spring is disposed on the outer wall of the sliding column, and the outer wall of the sliding column is slidably connected to the inside of the clamping plate.

[0011] Preferably, the interior of the outer casing has a groove, and the connecting post three is slidably connected to the interior of the outer casing through the groove.

[0012] Preferably, the connecting column three has an anti-slip groove inside.

[0013] Preferably, the outer wall of the support frame is fixedly connected to the inside of the test bench, and the outer wall of the second connecting column is slidably connected to the inside of the test bench.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the motor drives the cross plate to rotate, which in turn drives the transmission component to rotate. The connecting column 2 slides inside the support frame under the drive of the transmission component, which further drives the fixed plate and clamping plate to move, thereby achieving the centering and clamping of the seal. This avoids deviations in test data due to displacement of the seal during the test, and greatly improves the accuracy of the test results.

[0016] 2. In this utility model, by pulling the connecting column three, the sliding column is driven to slide inside the outer shell. After the connecting column three has moved a certain distance, the connecting column three is rotated to fix it inside the outer shell, so that the sliding column can be taken out from the inside of the clamping plate. Through the joint action of the connecting column three, the sliding column, the outer shell, the spring and the groove, the clamping plate can be quickly replaced so that it can be adapted to the testing requirements of seals of different sizes.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 An embodiment of this utility model provides a sealing component compression permanent deformation testing machine, including a testing machine body 1, a testing platform 2 fixedly connected to the upper surface of the testing machine body 1, a motor 3 installed inside the testing platform 2, a cross plate 4 connected to the output end of the motor 3, a transmission assembly installed inside the cross plate 4, a connecting column 7 rotatably connected to the outer wall of the transmission assembly, a clamping assembly installed at the top of the connecting column 7, and a support frame 10 slidably connected to the outer wall of the connecting column 7.

[0025] Specifically, motor 3 is first turned on. When motor 3 is running, the output end of motor 3 and the fixed action of cross plate 4 will drive cross plate 4 to rotate, which in turn drives the transmission component to rotate. When the transmission component rotates, it will drive connecting column 2 7 to slide inside the test table 2 and support frame 10, which will further drive the clamping component to move. Through the movement of the clamping component, the test seal is clamped and limited, ensuring that the seal is centered in the mold and improving the accuracy of the test results.

[0026] Reference Figures 1-3 The transmission assembly includes a connecting column 5, the bottom end of which is fixedly connected to the inside of the cross plate 4, and the top end of the connecting column 5 is rotatably connected to a transmission plate 6, the inside of which is rotatably connected to the outer wall of the connecting column 7; the clamping assembly includes a fixing plate 8, the top end of the connecting column 7 is fixedly connected to the lower surface of the fixing plate 8, and the outer wall of the fixing plate 8 is fitted with a clamping plate 9.

[0027] Specifically, when the cross plate 4 rotates, the fixing action of the cross plate 4 and the first connecting column 5 will drive the first connecting column 5 to rotate, which in turn will drive the transmission plate 6 to rotate. When the transmission plate 6 rotates, it will drive the second connecting column 7 to slide inside the test table 2 and the support frame 10. When the second connecting column 7 slides, the fixing action of the second connecting column 7 and the fixing plate 8 will drive the fixing plate 8 to move, which in turn will drive the clamping plate 9 to move.

[0028] Reference Figure 1 and Figure 4 The outer wall of the fixed plate 8 is fixedly connected to the outer shell 11. The outer shell 11 is provided with a sliding assembly. The outer wall of the sliding assembly is provided with a spring 14. The outer wall of the spring 14 is provided inside the outer shell 11. The outer wall of the sliding assembly is slidably connected to the inside of the clamping plate 9. The sliding assembly includes a sliding column 12. The outer wall of the sliding column 12 is slidably connected to the inside of the outer shell 11. The outer wall of the sliding column 12 is fixedly connected to a connecting column 3 13. The outer wall of the connecting column 3 13 is slidably connected to the inside of the outer shell 11. The outer wall of the spring 14 is provided on the outer wall of the sliding column 12. The outer wall of the sliding column 12 is slidably connected to the inside of the clamping plate 9.

[0029] Specifically, when it is necessary to disassemble and replace the clamping plate 9, firstly, the two connecting posts 13 inside the moving housing 11 are aligned. When the connecting posts 13 move, the sliding post 12 is moved by the fixing action of the connecting posts 13 and the sliding post 12. As the sliding post 12 moves, it cooperates with the housing 11 to compress the spring 14. When the connecting posts 13 move to the appropriate position, the connecting posts 13 are rotated to fix them inside the housing 11, thereby allowing the sliding post 12 to slide out from inside the clamping plate 9, thus removing the clamping plate. The limiting position of 9 further enables quick disassembly and removal of the clamping plate 9. When the clamping plate 9 needs to be installed, first, the clamping plate 9 and the fixing plate 8 are attached together, and then the connecting column 13 is rotated. At this time, the spring 14 will release its own elastic force, and the sliding column 12 will be pushed into the interior of the clamping plate 9, thereby limiting and fixing the clamping plate 9. Through the mutual cooperation between the outer shell 11, the sliding column 12, the connecting column 13 and the spring 14, the clamping plate 9 can be quickly installed or removed, so that the clamping plate 9 can adapt to the needs of different types of test seals.

[0030] Reference Figure 1 and Figure 4 The outer shell 11 has a groove 15 inside, and the connecting column 3 13 is slidably connected to the inside of the outer shell 11 through the groove 15; the connecting column 3 13 has an anti-slip groove 16 inside; the outer wall of the support frame 10 is fixedly connected to the inside of the test bench 2, and the outer wall of the connecting column 2 7 is slidably connected to the inside of the test bench 2.

[0031] Specifically, the groove 15 is used to limit the running trajectory of the connecting column 13, and further limit the movement trajectory of the sliding column 12. The anti-slip groove 16 is used to facilitate the operator to move the connecting column 13.

[0032] Working principle: The motor 3 drives the cross plate 4 to rotate, which in turn drives the connecting column 5 and the transmission plate 6 to rotate. When the connecting column 5 and the transmission plate 6 rotate, the connecting column 7 will slide inside the support frame 10 and the test table 2, which will in turn drive the fixing plate 8 to move. When the fixing plate 8 moves, it will drive the clamping plate 9 to move, thereby clamping and fixing the seal, preventing the seal from shifting, and improving the accuracy of the test data.

[0033] When the clamping plate 9 needs to be replaced, firstly, move the connecting column 13 to drive the sliding column 12 to slide inside the housing 11, further compressing the spring 14. After the connecting column 13 moves to the appropriate position, rotate the connecting column 13 to fix it inside the housing 11 through the groove 15, and then slide the sliding column 12 out from the inside of the clamping plate 9 to achieve quick disassembly of the clamping plate 9. During installation, first connect the fixing plate 8 and the clamping plate 9 together, and then rotate the connecting column 13. At this time, the spring 14 will reset the sliding column 12, allowing it to slide into the inside of the clamping plate 9, thereby fixing the clamping plate 9. This ensures that the clamping plate 9 can flexibly adapt to seals of different specifications, improving the versatility and operational efficiency of the testing machine.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
