Description

Technical Field

[0001] This utility model belongs to the technical field of wear resistance testing devices, specifically relating to a wear resistance testing device suitable for piston seals. Background Technology

[0002] A rubber abrasion tester is a device specifically designed to test the abrasion resistance of rubber materials. A rubber sample is mounted on a sample holder, and a loading system applies pressure, causing the sample to come into close contact with a friction wheel whose surface is coated with sandpaper. A drive system rotates the friction wheel at a set speed, causing the rubber sample to move relative to the wheel under the influence of friction, thus simulating the friction process between rubber and other object surfaces in actual use. As friction continues, the surface of the rubber sample gradually wears down. The abrasion resistance of the rubber material is evaluated by measuring indicators such as weight loss, volume loss, or surface wear depth after a certain number of friction cycles or time. For example, according to national standards, under specific test conditions, the abrasion amount (in volume or weight) of the rubber sample after a certain number of friction cycles is measured and compared with the abrasion amount of a standard rubber sample to obtain the abrasion resistance index of the rubber sample.

[0003] Specifically, in the piston seal wear resistance testing process, the traditional clamping process generally suffers from ergonomic defects and efficiency bottlenecks. Current tooling mostly uses screw-type mechanical clamps, requiring operators to manually adjust 6-8 bolts with a wrench or screwdriver. A single clamping operation takes 3-5 minutes and it is difficult to ensure uniform force on the circumference of the seal, reducing clamping accuracy and causing positioning misalignment that forces rework.

Current tooling often uses screw-type mechanical clamps, requiring operators to manually adjust 6-8 bolts with a wrench or screwdriver. A single clamping operation can take 3-5 minutes, and it is difficult to ensure uniform force on the circumference of the seal, reducing clamping accuracy and leading to positioning misalignment and forced rework.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[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 protection scope of the present utility model.

[0023] Please refer to Figures 1-6. This utility model provides the following technical solution: a wear resistance testing device for piston seals, including a test cabinet 1 and a control panel 2 installed on the surface of the test cabinet 1. A drive motor is installed inside the test cabinet 1, and the output end of the drive motor is connected to a rotating shaft 4. A support base 3 is connected to one side of the test cabinet 1, and a rotating shaft 4 is connected to the other side of the test cabinet 1. A sandpaper wheel 5 is connected to the output end of the rotating shaft 4. A cylinder mounting plate 6 is connected to the top of the support base 3, and a cylinder 7 is installed on the surface of the cylinder mounting plate 6. A support rod 8 is connected to the output end of the cylinder 7, and a clamping block 9 is connected to the bottom end of the support rod 8. A clamping spring 10 is connected to the inner wall of the opening of the clamping block 9. The other end of the clamping spring 10 is connected to a first linkage plate 11, and the other end of the first linkage plate 11 is connected to a limit plate 12. A guide block 13 is connected to the surface of the first linkage plate 11.

[0024] Preferably, the clamping spring 10 and the first linkage plate 11 form an elastic telescopic structure, and the clamping block 9 and the limiting plate 12 are both made of stainless steel.

[0025] Preferably, the inner wall of the opening of the clamping block 9 is provided with a guide groove that is compatible with the guide block 13, and the first linkage plate 11 forms a sliding connection structure with the guide block 13 and the guide groove.

[0026] In practical use, the guide block 13 is slid along the guide groove on the inner wall of the first linkage plate 11 to ensure the stability of the movement of the limiting plate 12 and to avoid angular deviation of the limiting plate 12.

[0027] Preferably, a collection box 14 is mounted on the surface of the support base 3, the top opening of the collection box 14 is tangent to the surface of the sandpaper wheel 5, and a cleaning drawer 15 is movably connected to one side of the collection box 14.

[0028] In practical use, by adopting a separate structure between the cleaning drawer 15 and the collection box 14, it is convenient to quickly transfer and clean the waste stored in the cleaning drawer 15.

[0029] Preferably, a fixing block 16 is connected to the surface of the collection box 14 near the cleaning drawer 15, a movable plate 17 is connected through the top of the fixing block 16, a second linkage plate 18 is connected to the bottom of the movable plate 17, and a linkage spring 19 is connected to one side of the second linkage plate 18.

[0030] In practical use, by pulling the movable plate 17, the linkage spring 19 is squeezed, which facilitates the subsequent up-and-down reciprocating movement of the limit plate 20, thus improving convenience.

[0031] Preferably, the second linkage plate 18 is connected to a limiting plate 20 on one side relative to the linkage spring 19, and the inner side of the limiting plate 20 is in contact with the surface of the cleaning drawer 15.

[0032] In practical use, the limiting plate 20 is abutted against one side of the cleaning drawer 15, thereby facilitating the limiting and fixing of the cleaning drawer 15 in the collection box 14.

[0033] The working principle of this utility model is as follows: First, by stretching the limiting plate 12 outward, the piston seal ring to be tested is attached to the clamping end of the clamping block 9. At this time, the first linkage plate 11 connected to the limiting plate 12 pulls the clamping spring 10 to elastically stretch, and then resets, driving the limiting plate 12 to reset synchronously. At the same time, the guide block 13 moves directionally along the guide groove on the inner wall of the clamping block 9, thereby quickly clamping and stabilizing the piston seal ring to be tested. Then, the cylinder 7 is driven to bring the piston seal ring close to the sandpaper wheel 5. The rotation of the sandpaper wheel 5 performs a friction test on the piston seal ring. Then, the wear is measured by an electronic scale to accurately determine the wear resistance of the piston seal ring. In addition, when the sandpaper wheel 5 rotates to test the piston seal ring, the waste on the surface of the sandpaper wheel 5 is scraped into the collection box 14 through the opening at the top of the collection box 14. Then, by pulling the movable plate 17 on the surface of the fixed block 16, the second linkage plate 18 is driven. The compression spring 19 causes the limiting plate 20 to disengage from the limiting structure between it and the cleaning drawer 15, making it easier to remove the cleaning drawer 15 from the collection box 14 and thus facilitate the transfer and cleaning of the cleaning waste, thereby improving the practicality of the wear resistance testing device.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
