Description
Technical Field
[0001] The present invention relates to the technical field of rubber material wear detection, and in particular to a wear test device for exploring rubber materials. Background Art
[0002] Finished products made from rubber materials are various rubber products produced from natural and synthetic rubber or recycled waste rubber. They can be used in industries such as daily use, medicine, mining, transportation, machinery, and construction. Among them, sealing rings made from rubber materials are widely used components, often appearing in devices that come into contact with liquids and require sealing. Rotating sealing rings, due to long-term rotation, will generate friction with the rotating parts. Therefore, before using rotating sealing rings, they must be subjected to wear tests to detect their wear resistance.
[0003] At present, in the test process of rotating seal rings, the rubber material used to make the rotating seal ring is often subjected to Akron wear test (a cylindrical rubber specimen is pressed on the rotating friction part at a certain angle and load, and the specimen slides and rolls on the friction part, and the volume loss or wear within a specified stroke is measured to obtain the specimen wear index). However, this test process cannot test the unexpected situations that may occur during the actual use of the seal ring, such as: 1. In manual coating and actual production consumption, different amounts of sealing oil (paste) will cause differences in wear resistance when applied to the surface of the rotating sealing ring; 2. When the rotary seal ring is set at both ends of the load-bearing rotating shaft, due to the certain offset of the rotating shaft, the rotating part will be offset, and the wear of the rotary seal ring will be different at different places. This will undoubtedly cause a deviation between the test data of the rotating seal ring and the wear amount during actual use, which will increase the test error and reduce the applicable scope of the seal ring test.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances.
[0021] Example, see Figures 1 to 10 A wear test device for exploring rubber materials includes a test bench 1 for testing the wear of a rubber sealing ring 2. The test bench 1 is provided with a control test mechanism for simulating the test of the rubber sealing ring 2. The control test mechanism consists of an offset wear component and a seal adjustment component. The test bench 1 is provided with a wear test mechanism for detecting the wear amount of the rubber sealing ring 2. The wear test mechanism consists of a wear drive component and a wear detection component. A hollow loading column 3 is slidably connected to the test bench 1. It should be noted that the sealing oil mentioned in this application can also be replaced by sealing paste, and the rubber sealing ring 2 is an existing rotating sealing ring. By placing the rubber sealing ring 2 on the loading column 3, its inner ring can be locked, so that it is convenient to test the rotating sealing part of the rubber sealing ring 2 during the subsequent simulation control test.
[0022] like Figures 2 to 6 As shown, the offset wear assembly includes a lifting electric push rod 4 arranged in the detection platform 1, the output end of the lifting electric push rod 4 is fixed with a hydraulic lifting platform 5, and the hydraulic lifting platform 5 is movably connected with an offset push rod 501, and the offset push rod 501 is fixedly connected to the loading column 3 through a control ring; Furthermore, the inner wall of the loading column 3 is slidably connected to a positioning column 301 via a tension spring, and an offset control seat 101 is fixed to the inner side of the detection platform 1. The offset control seat 101 is provided with a locking groove and an offset sliding groove adapted to the positioning column 301; Furthermore, a T-shaped cavity with a vent hole at the bottom is provided inside the hydraulic lifting platform 5. An offset control slide 6 is slidably connected in the T-shaped cavity. The offset control slide 6 is fixedly connected to a magnetic column 601 through a connecting rod. The top of the magnetic column 601 is magnetically connected to an electromagnet 602 fixedly mounted on the driving platform 11. It should be noted that when the electromagnet 602 is turned on, it attracts the magnetic column 601 to rise, driving the offset control slide 6 to rise, squeezing the liquid in the hydraulic lift 5 toward the offset push rod 501, causing the offset push rod 501 to generate a thrust on the loading column 3, thereby causing the rubber sealing ring 2 mounted on the loading column 3 to have a radially outward movement relative to the wear sleeve 12, forming a foundation for offset wear. Based on the above, when the electromagnet 602 is not conducting, the offset control plunger 6 is in a suspended state and does not generate thrust on the offset push rod 501. The positioning column 301 is limited in elevation by the locking groove, so that the loading column 3 is no longer affected by the offset push rod 501. This allows the offset wear test of the rubber seal 2 to be separated from the seal oil wear test. Based on the above, an electromotive force detection device can be added and connected to the electromagnet 602. When the electromagnet 602 is not conducting, the rubber sealing ring 2 will generate a large deflection force on the rubber sealing ring 2 at the initial start-up and the final closing stage of the wear sleeve 12 due to the rotating part, causing the rubber sealing ring 2 to produce a small relative movement or deformation. At this time, an extrusion force is generated on the loading column 3, forcing the offset push rod 501 to produce a relative displacement relative to the hydraulic lifting platform 5, which is detected by the electromotive force detection device. In this way, the actual wear state of the rubber sealing ring 2 at the initial and final stages of the wear test can be simulated, and the induced current and voltage are generated by the movement of the magnetic column 601 relative to the closed coil in the electromagnet 602. The induced current and voltage are detected by the electromotive force detection device, thereby achieving a convenient detection of whether the rubber sealing ring 2 will have a large deformation under the actual wear at the initial and final stages of the wear test. A further advantage of adopting the above method is that when the lifting electric push rod 4 drives the hydraulic lifting platform 5 to rise, it drives the positioning column 301 to move to the height of the offset slide groove, and the control ring can be pushed by the offset push rod 501 to push the loading column 3 outward, so that the loading column 3 is offset and squeezed relative to the wear sleeve 12, providing a basis for detecting the offset wear of the rubber sealing ring 2; Based on the above, when the extrusion force of the rubber sealing ring 2 needs to be changed, the extrusion force of the rubber sealing ring 2 can be changed by changing the adsorption force of the electromagnet 602 on the magnetic column 601 .
[0023] like Figures 4 to 7 As shown, the sealing adjustment assembly includes a control cylinder 7 disposed on the top of the loading column 3. The control cylinder 7 is connected to the oil quantity control module through a control rod 701. An injection head is provided on the side of the control cylinder 7. Further, if Figure 7 and Figure 10 As shown, the oil quantity control module includes a sealed lower pressure frame 8 arranged on the top of the control cylinder 7, the top of the sealed lower pressure frame 8 is slidably connected to a locking clip 802 through a compression cylinder 801, the inner wall of the sealed lower pressure frame 8 is slidably connected to an oil quantity adjustment column 9 with a quantitative annular groove on the surface, the locking clip 802 is engaged with the quantitative annular groove, and the bottom of the oil quantity adjustment column 9 is in contact with the control rod 701 through a rotating column, and an oil quantity electric push rod 10 is provided at the bottom of the sealed lower pressure frame 8, and the oil quantity electric push rod 10 is fixedly mounted on the wear lifting frame 15; It should be noted that: when the control cylinder 7 is clamped on the top of the loading column 3 and the oil quantity adjustment column 9 is pressed downward, the amount of sealing oil applied to the rubber sealing ring 2 below by the multiple control cylinders 7 can be different. Therefore, during the friction between the wear sleeve 12 and the rubber sealing ring 2, the wear resistance of the rubber sealing ring 2 under different sealing oil quantities can be quickly explored; A further advantage of adopting the above method is that before the oil-quantity electric push rod 10 drives the sealing lower pressure frame 8 to descend, by locking the locking clip 802 in the quantitative annular groove at the corresponding position, when the sealing lower pressure frame 8 descends, the top of the control rod 701 is squeezed, and the sealing oil is squeezed out from the injection head on the side of the control cylinder 7 and applied to the sleeve portion of the rubber sealing ring 2. Under the rotation of the wear sleeve 12, the applied sealing oil can be evenly coated on the outside of the rubber sealing ring 2, thereby completing the quantitative control of the sealing oil.
[0024] like Figure 8 and Figure 9 As shown, the wear drive assembly includes a drive platform 11 fixed on the test platform 1, and the drive platform 11 is rotatably connected to the wear sleeve 12 through a star-ray connecting rod. A planetary gear set 13 is arranged between the wear sleeve 12 and the drive platform 11, and a servo motor 14 is arranged on the top of the planetary gear set 13.
[0025] Furthermore, a wear ring 1201 is clamped on the top of the wear sleeve 12. The planetary gear set 13 consists of a sun gear 1301 fixed to the output shaft of the servo motor 14 and a planetary gear 1302 fixed to the outside of the wear sleeve 12. The output shaft of the servo motor 14 is rotatably connected to the wear lifting frame 15 through a bearing. A wear electric push rod 16 is provided at the bottom of the wear lifting frame 15. It should be noted that: when it is necessary to perform a wear test on the rubber sealing ring 2, the wear lifting frame 15 is driven to rise by the wear electric push rod 16 to expose the loading column 3 so that the rubber sealing ring 2 can be quickly sleeved on the surface of the loading column 3, and when the wear lifting frame 15 descends to sleeve the wear sleeve 12 on the outside of the rubber sealing ring 2, the servo motor 14 is started to drive the star gear 1301 to rotate, so that the planetary gear 1302 rotates synchronously, driving the wear sleeve 12 to rotate and wear the outside of the rubber sealing ring 2, thereby completing the wear test process of the rubber sealing ring 2.
[0026] A further advantage of adopting the above method is that a plurality of wear strips are provided at the bottom of the wear ring 1201. After the wear test is completed, the wear ring 1201 can be replaced to ensure that the friction force exerted on the rubber sealing ring 2 under the same wear conditions is the same during each wear test.
[0027] like Figures 1 to 6 As shown, the wear detection assembly includes a development detection ring 17 provided on the detection platform 1, and a development indicator light 302 adapted to the development detection ring 17 is provided on the outer side of the loading column 3; Furthermore, a receiving platform 303 located below the rubber sealing ring 2 is fixed to the outside of the loading column 3. A storage groove for storing grinding waste of the rubber sealing ring 2 is provided on the receiving platform 303, and the receiving platform 303 is adapted to the development detection ring 17. The loading column 3 is connected to the loading ring 305 via a hydraulic push rod 304. A loading groove is provided on the outer surface of the loading ring 305. The rubber sealing ring 2 is sleeved on the loading column 3 through the loading groove. Multiple hydraulic push rods 304 and loading rings 305 are arranged in a circumferential array. The development indicator light 302 adopts a divergent light source and is arranged at the joint of the two loading rings 305. A wear lower limit line is engraved on the development detection ring 17 to limit the wear amount of the rubber sealing ring 2 after the wear test. It should be noted that when the rubber sealing ring 2 is subjected to wear tests under various conditions, when the expanded rubber sealing ring 2 descends to the detection level of the developing detection ring 17, the diffuse light source of the developing indicator light 302 can be used to display the stretched rubber sealing ring 2 as a shadow at the developing detection ring 17, and the maximum wear of the rubber sealing ring 2 is limited by the wear lower limit line, thereby speeding up the detection process during each wear test. The above-mentioned method has the following advantages: when the positioning column 301 deviates from the control seat 101 to squeeze the bottom wall of the locking groove, the positioning column 301 is squeezed into the loading column 3, driving the hydraulic push rod 304 to move outward, so that the rubber sealing ring 2 sleeved on the plurality of loading rings 305 is stretched, so that the defects of the worn part of the rubber sealing ring 2 can be magnified by the light emitted by the development indicator light 302, and the maximum wear amount can be limited by two parallel wear lower limit lines, so that it can be known whether the diameter of the rubber sealing ring 2 after wear meets the wear lower limit requirement when it is developed. Furthermore, during the wear test, the offset push rod 501 in the hydraulic lifting platform 5 can be driven down by the lifting electric push rod 4, so that the loading column 3 is lowered and the rubber sealing ring 2 is driven to expand outward. In combination with the development visual inspection, it can be quickly known whether the wear amount of the rubber sealing ring 2 meets the requirement during the experiment. Based on the above, a photosensitive sensor can also be directly set on the development detection ring 17 mentioned in this application to capture the shadow of the rubber sealing ring 2 after the development indicator light 302 is magnified, thereby realizing digital detection.
[0028] Working principle: When the present invention performs wear detection on the rubber sealing ring 2, multiple rubber sealing rings 2 can be set as a dry friction group, an oil friction group, an offset friction group and an offset oil friction group according to the influence of single factors and double factors on the wear detection. The dry friction group, the oil friction group, the offset friction group and the offset oil friction group respectively correspond to various states of the rubber sealing ring 2 not being coated with sealing oil and not generating offset extrusion, being coated with different amounts of sealing oil and generating no offset extrusion, not being coated with sealing oil and generating offset extrusion, and generating offset extrusion after being coated with different amounts of sealing oil.
[0029] When the rubber sealing ring 2 of the dry friction group is subjected to a wear test, the wear lifting frame 15 is driven to rise by the wear electric push rod 16 to expose the loading column 3 so that the rubber sealing ring 2 can be quickly sleeved on the surface of the loading column 3. Then, when the wear lifting frame 15 descends to sleeve the wear sleeve 12 on the outside of the rubber sealing ring 2, the servo motor 14 is started to drive the star gear 1301 to rotate, so that the planetary gear 1302 rotates synchronously, driving the wear sleeve 12 to rotate and wear the outside of the rubber sealing ring 2, thereby completing the wear test process of the dry friction group of the rubber sealing ring 2.
[0030] When the rubber sealing ring 2 of the oil friction group is subjected to a wear test, before the dry friction group is worn, the locking clip 802 is locked in the quantitative annular groove at the corresponding position on the oil adjustment column 9 at different oil volumes, so that when the sealing lower pressure frame 8 descends, the top of the control rod 701 is squeezed, and the sealing oil is squeezed out from the injection head on the side of the control cylinder 7 and applied to the sleeve portion of the rubber sealing ring 2. Under the rotation of the wear sleeve 12, the applied sealing oil can be evenly coated on the outside of the rubber sealing ring 2, completing the quantitative control of the sealing oil and the wear test process of the oil friction group.
[0031] When the rubber sealing ring 2 of the offset friction group is subjected to a wear test, the electromagnet 602 is turned on to attract the magnetic column 601 to rise, driving the offset control slide 6 to rise, squeezing the liquid in the hydraulic lifting platform 5 toward the offset push rod 501, so that the offset push rod 501 generates a thrust on the loading column 3, thereby causing the rubber sealing ring 2 mounted on the loading column 3 to have a radially outward movement trend relative to the wear sleeve 12. Under the rotation of the wear sleeve 12, the multiple rubber sealing rings 2 under the offset are worn, completing the wear test process of the offset friction group.
[0032] When the rubber sealing ring 2 of the offset oil friction group is subjected to a wear test, the oil amount adjustment column 9 of the oil friction group with different oil amounts is pre-set, and then the wear sleeve 12 evenly coats the sealing oil on the outer surface of the rubber sealing ring 2, and then the wear test process of the offset friction group is carried out, thereby realizing the wear test process of the offset oil friction group.
[0033] Based on the above, when the friction group is rubbed under various test conditions, the expanded rubber sealing ring 2 is lowered to the detection level of the development detection ring 17, and the development indicator light 302 is turned on, so that its light source diffuses and emits light outward, and the stretched rubber sealing ring 2 is displayed as a shadow at the development detection ring 17, and the maximum wear of the rubber sealing ring 2 is limited by the wear lower limit line, thereby realizing rapid detection of the wear of the rubber sealing ring 2.
[0034] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
