Description

A test device for long-stroke surface wear of irregularly shaped seals Technical Field

[0001] This utility model belongs to the field of testing device technology, and more specifically, it relates to a long-stroke planar wear testing device for irregularly shaped seals. Background Technology

[0002] A seal wear test device is a specialized device used to simulate and evaluate the wear resistance of sealing materials or components under actual working conditions. It simulates reciprocating movement and contact with the seal, and monitors leakage, friction, and wear morphology in real time through a background system, thereby measuring the wear life of irregularly shaped seals.

[0003] Based on existing technology, it has been found that existing wear testing devices cannot easily fix the seals during use to ensure the stability of the test. In addition, during use, the seals will generate debris due to long-term wear. Since the seals are mostly made of rubber or flexible materials, they are prone to sticking together. If they are not cleaned in time, they will affect subsequent tests. There is no corresponding cleaning structure. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides a long-stroke planar wear testing device for irregularly shaped seals. This solves the problem that existing wear testing devices cannot easily fix the seals during use to ensure stability during testing. Furthermore, existing wear testing devices generate debris from long-term wear of the seals, and since most seals are made of rubber or flexible materials, they are prone to sticking together. If not cleaned in time, this will affect subsequent tests. The device lacks a corresponding cleaning structure.

[0005] This utility model discloses a long-stroke planar wear testing device for irregularly shaped seals, achieved through the following specific technical means:

[0006] A long-stroke planar wear testing device for irregularly shaped seals includes a testing mechanism, an adjustment mechanism, a fixing mechanism, and a cleaning mechanism;

[0007] The testing mechanism is equipped with an adjustment mechanism; the fixing mechanism is mounted on the adjustment mechanism; the cleaning mechanism is located on the top side of the testing mechanism.

[0008] The testing mechanism includes: a main body, with slide rails provided on both sides of the top of the main body; a screw A rotatably mounted on the main body; a movable component slidably mounted on the slide rails; and a screw A provided on the movable component.

[0010] Furthermore, a gear is provided on the output shaft of the motor on the main body side; a gear is fixedly installed on the screw A, and the gear on the screw A meshes with the gear on the motor on the main body side.

[0011] Furthermore, the adjustment mechanism includes: a top member, a screw B, and a fixing rod;

[0012] The top component is fixedly installed on the top left side of the main body; the top component is rotatably connected to screw A; screw B is rotatably installed on the top of the top component; a handle is provided on screw B; and the fixing rod is fixedly installed on the top of the top component.

[0013] Furthermore, the fixing mechanism includes: a fixing frame, a screw C, and a fixing member;

[0014] The fixing frame is slidably mounted on the fixing rod; the fixing frame is provided with a screw B; the screw C is disposed inside the threaded hole on the fixing frame; the fixing member is provided with a screw C; a sealing member is provided between the fixing member and the fixing frame.

[0015] Furthermore, the cleaning mechanism also includes: a mounting box and a fan;

[0017] Furthermore, the bottom of the cleaning component is configured as a triangular structure; the bottom of the cleaning component is in contact with the top of the moving component; and a dustproof plate is provided at the bottom of the mounting box.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this device, a screw C and a fixing component are provided. The screw C is mounted on a fixed frame, and the fixing component is connected to the screw C. Thus, during use, by fitting the sealing component onto the fixing component and lifting the fixing component, the top of the sealing component contacts the bottom of the fixed frame. The screw C limits the two sides of the sealing component. At the same time, the screw C connects the fixed frame and the fixing component, thus conveniently fixing the sealing component. By manually rotating the screw B, the fixed frame moves on the fixed rod, so that the bottom of the sealing component can contact the top of the moving component, thus facilitating the testing of sealing components of different diameters.

[0020] 2. This device includes a cleaning component and a blower. The cleaning component is fixedly mounted at the bottom of the mounting rod, while the blower is located inside the mounting box. During use, when the moving component moves, the motor inside the mounting box drives the blower to rotate, and the blower heats the surface of the moving component via an internal electric heating wire. This heats up the debris adhering to the moving component, causing it to loosen. Simultaneously, the moving component comes into contact with the cleaning component, causing the mounting rod to move upward and compress the spring. This brings the bottom of the cleaning component into contact with the top of the moving component, thus scraping off the debris adhering to the moving component as it moves.

[0034] As shown in Figure 1, a gear is provided on the output shaft of the motor on the side of the main body 101; a gear is fixedly installed on the screw A103, and the gear on the screw A103 meshes with the gear on the motor on the side of the main body 101.

[0035] As shown in Figure 1, the adjusting mechanism 2 includes: a top member 201, a screw B202, and a fixing rod 203; the top member 201 is fixedly installed on the top left side of the main body 101; the top member 201 is rotatably connected to the screw A103; the screw B202 is rotatably installed on the top of the top member 201; a handle is provided on the screw B202; the fixing rod 203 is fixedly installed on the top of the top member 201; the screw B202 is used to manually rotate, thereby driving the fixing frame 301 to move on the fixing rod 203, so as to adapt to seals of different diameters.

[0036] As shown in Figure 3, the fixing mechanism 3 includes: a fixing frame 301, a screw C302, and a fixing member 303; the fixing frame 301 is slidably mounted on the fixing rod 203; the fixing frame 301 is provided with a screw B202; the screw C302 is disposed inside a threaded hole on the fixing frame 301; the fixing member 303 is provided with a screw C302; a sealing member is provided between the fixing member 303 and the fixing frame 301; the sealing member is used to fit onto the fixing member 303, and by lifting the fixing member 303, the top of the sealing member contacts the bottom of the fixing frame 301, and the screw C302 limits the two sides of the sealing member, while the screw C302 connects the fixing frame 301 and the fixing member 303, thereby conveniently fixing the sealing member.

[0039] The specific usage and function of this embodiment are as follows:

[0040] In this invention, when using the device, the sealing element is fitted onto the fixing element 303. By lifting the fixing element 303, the top of the sealing element contacts the bottom of the fixing frame 301. The screw C302 limits the two sides of the sealing element and connects the fixing frame 301 and the fixing element 303, thus conveniently fixing the sealing element. By manually rotating the screw B202, the fixing frame 301 moves on the fixing rod 203, allowing the bottom of the sealing element to contact the top of the moving part 104. This facilitates testing of sealing elements of different diameters. The motor on the main body 101 rotates, and the gear meshes with the gear on the screw A103, thereby... The screw A103 drives the movable part 104 to move on the slide rail 102, thereby making contact with the seal and conducting a friction test. When the movable part 104 moves, the motor inside the mounting box 404 drives the fan 405 to rotate and heats it through the internal electric heating wire. The heat is then blown onto the surface of the movable part 104 by the fan 405, causing the seal debris adhering to the movable part 104 to loosen due to the heat. At the same time, the movable part 104 comes into contact with the cleaning part 403, causing the mounting rod 402 to move upward and compress the spring, so that the bottom of the cleaning part 403 comes into contact with the top of the movable part 104. Thus, the seal debris attached to the movable part 104 is scraped off when the movable part 104 moves.
