Description

Technical Field

[0001] This utility model relates to the field of sealing ring testing technology, and in particular to an irregularly shaped sealing ring compression testing fixture. Background Technology

[0002] A sealing ring is a component or measure that prevents fluid or solid particles from leaking between adjacent mating surfaces and prevents external impurities such as dust and moisture from entering the interior of machinery and equipment.

[0003] After the production of irregularly shaped sealing rings, a compression test is generally required to detect the deformation of the sealing ring under compression. However, existing test fixtures generally do not have a device to fix the position of the sealing ring, thus failing to guarantee the stability of the sealing ring during the test. Some test fixtures only observe the deformation of the sealing ring without a device to observe the test pressure, which causes some trouble for people to read the test data. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology. By moving multiple moving rods in multiple through slots, the space formed by the multiple moving rods is increased, and the multiple moving rods come into contact with the inner wall of the sealing ring, thereby fixing the sealing ring and improving the stability of the sealing ring during the compression process. This invention proposes an irregularly shaped sealing ring compression test fixture.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0021] Reference Figure 1-3 An irregularly shaped sealing ring compression test fixture includes a base 1, with multiple symmetrically arranged support rods 3 on the upper end of the base 1. A top plate 4 is provided on the upper end of the support rods 3. Two symmetrically arranged telescopic cylinders 5 are threaded through the upper end of the top plate 4. A moving plate 6 is provided at the telescopic ends of the two telescopic cylinders 5. A pressure ring 7 is provided at the lower end of the moving plate 6. The base 1 is hollow. A fixing mechanism for fixing the sealing ring is provided on the upper end of the base 1. The fixing mechanism includes multiple circumferentially arranged through grooves 10 on the upper end of the base 1. Each through groove 10 is provided with a limiting rod 11. A moving rod 12 is slidably connected through the outer wall of each limiting rod 11. By moving the multiple moving rods 12 within the multiple through grooves 10, the space formed by the multiple moving rods 12 is enlarged, allowing the multiple moving rods 12 to contact the inner wall of the sealing ring, thereby fixing the sealing ring and improving its stability during compression.

[0022] The base 1 is provided with a moving mechanism for moving the fixed mechanism. The moving mechanism includes a rotating shaft 15 rotatably connected in the base 1. The outer wall of the rotating shaft 15 is provided with a turntable 17. The turntable 17 is provided with a plurality of circumferentially arranged arc grooves 18. A plurality of moving rods 12 are respectively located in the plurality of arc grooves 18 and slidably connected to them.

[0023] The base 1 has a fixing block 14 at the bottom. The fixing block 14 is rotatably connected to the front end of the base 1 with an operating rod 2. The end of the operating rod 2 and the outer wall of the rotating shaft 15 are both provided with bevel gears 16, and the two bevel gears 16 mesh with each other.

[0024] Each of the lower ends of the multiple moving rods 12 and the outer wall is provided with two symmetrically arranged limiting plates 19, and the multiple limiting plates 19 are slidably connected to the upper and lower ends of the turntable 17 respectively.

[0025] A pressure sensor 13 is provided at the lower end of the movable plate 6, and a display screen 8 is provided at the upper end of the top plate 4. The pressure sensor 13 and the display screen 8 are connected by a connecting line 9. As the movable plate 6 continues to move downward, the pressure ring 7 continuously compresses the sealing ring, and the applied pressure is displayed on the display screen 8, making it easy for people to view the experimental data. The operation is convenient and brings convenience to people.

[0026] When using this invention, during the compression test of the irregular sealing ring, the irregular sealing ring is placed on the upper end of the base 1, so that multiple moving rods 12 are all in the middle of the sealing ring. Rotating the operating rod 2 causes the rotating shaft 15 to rotate due to the meshing of the bevel gear 16 between the operating rod 2 and the rotating shaft 15. This causes the turntable 17 on the outer wall of the rotating shaft 15 to rotate. Through the sliding connection between the multiple moving rods 12 and the arc-shaped groove 18, and the limiting action of multiple pairs of limiting plates 19 and limiting rods 11 on the moving rods 12, the multiple moving rods 12 move within the multiple through grooves 10 respectively, thus enabling the multiple moving rods to move... The space formed by the rods 12 becomes larger, allowing multiple moving rods 12 to contact the inner wall of the sealing ring, thus fixing the sealing ring and improving its stability during compression. At this time, the two telescopic cylinders 5 are activated, causing the telescopic ends of the cylinders 5 to push the moving plate 6 downward, thereby bringing the pressure ring 7 at the lower end of the moving plate 6 into contact with the sealing ring. At this time, the pressure sensor 13 also contacts the base 1. As the moving plate 6 continues to move downward, the pressure ring 7 continuously compresses the sealing ring, and the applied pressure is displayed on the display screen 8, making it easy for people to view the experimental data. The operation is convenient and brings convenience to people.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
