[0002] A rubber sealing ring is an annular component made of elastic rubber material. It is widely used in machinery, automobiles, aerospace, chemical industry and other fields. It is mainly used to prevent leakage of fluids (such as liquids and gases) between different components. Its main function is to ensure the sealing performance of the system in harsh environments such as high pressure, high temperature and corrosion by filling and sealing the gap between two components. Due to its good elasticity and chemical corrosion resistance, the rubber sealing ring can adapt to various working conditions and ensure the normal operation and safety of the equipment.

[0003] The existing rubber sealing ring production lacks a burr trimming device that can fix sealing rings of different sizes. The problem with the above technology is that the fixing device needs to be frequently replaced when trimming the burrs of sealing rings of different sizes, which not only increases the complexity and time cost of the operation, but also easily introduces human errors, affecting the accuracy and consistency of trimming. Secondly, traditional fixing devices can often only adapt to sealing rings of specific sizes and cannot flexibly respond to products of different specifications on the production line, limiting the flexibility and efficiency of the production line. In addition, due to loose or unstable fixation, the sealing ring may be displaced or deformed during the trimming process, resulting in incomplete trimming or new defects, seriously affecting the final quality and performance of the product. These problems not only increase production costs, but may also affect customer satisfaction and market competitiveness. Utility Model Content

The travel groove 108 is opened on the surface of the fixed plate 109, and the inner wall of the mounting box 103 is slidingly connected to the surfaces of the six support plates 104 by a sliding groove, so that the support plate 104 can flexibly adjust its extension distance according to the rotation position of the cam block 102, thereby adapting to different The sealing rings of the same diameter improve the versatility and flexibility of the equipment. The auxiliary mechanism 2 includes a small motor 201, a driving gear 202, a driven gear 203 and a fixed box 204. The output end of the small motor 201 is fixedly connected to the inner wall of the driving gear 202, the surface of the driving gear 202 is meshed with the surface of the driven gear 203, the inner wall of the driven gear 203 is fixedly connected to the surface of the fixed box 204, and the driving gear 202 is meshed with the driven gear 203, realizing the smooth transmission of power from the driving gear 202 to the driven gear 203, which can not only provide a stable rotation speed, but also ensure the smooth rotation of the sealing ring during the processing, avoiding quality problems caused by unstable rotation. A limit plate 3 is provided on the upper surface of the support plate 104. The lower surface of plate 3 is fixedly connected to the upper surface of support plate 104.

The surface of the small motor 201 is fixedly connected to the inner wall of the support frame 6, and the surface of the fixed box 204 is rotatably connected to the inner wall of the support frame 6 through a bearing. The rotation connection between the fixed box 204 and the support frame 6 is achieved through the bearing, ensuring that the fixed box 204 can rotate smoothly in the support frame 6.

It needs to remain fixed with the support of the fixed box 204, preventing the installation box 103 from displacement or shaking during operation, ensuring the stability and precision of the sealing ring during processing.

[0024] The working principle of this utility model:

[0025] When trimming the burrs of the sealing strip, the first step is to perform a preliminary positioning step for the sealing ring. The operator needs to put the sealing ring on the front end of the installation box 103 and manually push it inward until it is in close contact with the limit plate 3 on the support plate 104. This step ensures that the sealing ring can maintain a stable position during subsequent operations. Next, the driving motor 101 inside the fixing box 204 begins to work. When the motor is started, its output end will drive the cam block 102 to rotate. Because the cam block 102 has a certain slope on its surface, as the cam block 102 rotates, it can simultaneously apply thrust to the lower ends of the six support plates 104 evenly distributed around the installation box 103. Due to the change in the slope of the cam block 102 surface, the rotation at different angles can make the support plates 104 extend outward by different distances, which realizes the effective fixation of sealing rings of various sizes. In order to ensure that the support plates 104 can smoothly extend outward and retract inward, the rear end of each support plate 104 is equipped with a connecting rod 105. These connecting rods 105 are connected to the matching blocks 107 on the fixed disk 109 through springs 106. When the support plate 104 moves outward, the connecting rod 105 slides in the travel groove 108 on the fixed disk 109. At the same time, the spring 106 is stretched and stores energy. Once the cam block 102 no longer provides support, the spring 106 will release the previously stored energy and pull the support plate 104 back into the installation box 103 to restore the initial state. Finally, in order to remove the burrs on the surface of the sealing ring, it is necessary to start the small motor 201 in the support frame 6. This small motor 201 drives the driving gear 202 to rotate through its output end. The driving gear 202 engages with the driven gear 203 on the fixed box 204, thereby driving the fixed sealing ring to rotate slowly. The operator can use the preset grinding strip 7 on the console to process the surface of the sealing ring. After completing all processing steps, you only need to simply stop the operation of the small motor 201 and let the drive motor 101 run in reverse to easily remove the processed sealing ring.
