[0002] A sealing ring is a key component used in sealing devices in mechanical equipment. Its main function is to form a sealed environment inside the equipment to prevent liquid or gas leakage and ensure the normal operation and safety of the equipment. Sealing rings are usually made of rubber, plastic, metal and other materials and have different shapes and sizes to meet different sealing requirements.

[0003] After the rubber sealing ring is injection molded by the upper mold and the lower mold, a circle of burrs will remain on its inner and outer walls at the junction of the upper mold and the lower mold.

[0004] When trimming the burrs of rubber sealing rings, workers are required to support the rubber sealing rings for trimming, which requires a lot of manpower and time, and the efficiency is relatively low. Secondly, the quality of the trimming of the rubber sealing rings is affected by the skills and experience of the workers, and there may be problems such as uneven and uneven trimming. Therefore, a burr trimming device for sealing ring processing is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a burr trimming device for sealing ring processing, comprising a base 1, a support platform 2 is fixedly connected to the top of the base 1, the support platform 2 is provided with a groove, which can adapt to sealing rings of different sizes, a connecting block 3 is fixedly connected to the inner side of the support platform 2, and a limiting component is arranged on the inner wall of the connecting block 3. The limiting component is provided with two groups, which are symmetrically arranged with the central axis of the connecting block 3 as the symmetry axis. The limiting component includes a shift rod 41, and the shift rod 41 is set to a U shape to increase stability. The outer wall of the bottom end of the shift rod 41 is slidably connected to the inner wall of the connecting block 3, and the lower inner wall of the shift rod 41 is slidably connected to a baffle 42.

[0033] Reference Figure 2 Figure 3 The baffle plate 42 is elastically connected to the shift rod 41 through a compression spring 43. The elasticity of the compression spring 43 makes the threaded rod 44 push the shift rod 41 to restrict the sealing ring. During the horizontal pulling process, the sealing ring makes the limiting sheet 51 close to the surface of the sealing ring, thereby improving the shearing effect. The front end of the baffle plate 42 is rotatably connected to the threaded rod 44. The outer wall of the threaded rod 44 is threadedly connected to the inner wall of the front end of the connecting block 3. The shift rod 41 is driven to slide on the inner wall of the connecting block 3 by rotating the threaded rod 44.

[0034] Reference Figure 3 and Figure 4 A trimming assembly is provided on the upper side of the shift rod 41, and the trimming assembly includes a limiting plate 51, the front side of the limiting plate 51 is fixedly connected to the rear side of the upper end of the shift rod 41, and a trimming blade 52 is slidably connected to the inner wall of the upper end of the shift rod 41, which can facilitate the installation of the trimming blade 52, and a bolt 53 is threadedly connected to the inner wall of the right side of the shift rod 41, and the outer wall of the bolt 53 is threadedly connected to the right end of the trimming blade 52, and the trimming blade 52 is limited by the bolt 53, and it is convenient for workers to replace the trimming blade 52. A card slot 54 is provided at the front end of the limiting plate 51, which can limit the position of the trimming blade 52, and the rear side of the trimming blade 52 slides on the inner wall of the card slot 54. The limiting plate 51 is set to a polyethylene material, which can relatively reduce the friction with the sealing ring and reduce the damage to the sealing ring.

[0035] Reference Figure 1 and Figure 5 A stabilizing component is provided at the top of the base 1, and the stabilizing component includes a shell 61. The bottom end of the shell 61 is fixedly connected to the top of the base 1. A slider 62 is slidably connected to the inner wall of the rear side of the shell 61. The slider 62 is elastically connected to the shell 61 through a return spring 63. The initial state of the return spring 63 is a stretched state. The slider 62 is driven downward by the elastic force of the return spring 63, so that the clamp 65 restricts the sealing ring. A ball 64 is rotatably connected to the inside of the shell 61, and a clamp 65 is fixedly connected to the lower side of the front end of the slider 62. The clamp 65 is set to a polyethylene material, which can relatively reduce the friction with the sealing ring. A plurality of groups of balls 64 are provided, and the plurality of groups of balls 64 are evenly arranged on the inner side of the shell 61. The plurality of groups of balls 64 roll on the inner wall of the shell 61, thereby replacing the direct sliding friction between the shell 61 and the sealing ring, making the worker's operation smoother.

[0036] Working principle: During use, when the burrs of the sealing ring need to be trimmed, the slider 62 is pulled upward to slide on the inner wall of the shell 61, and the reset spring 63 is stretched at the same time. At this time, the sealing ring to be trimmed is placed on the shell 61, and then the slider 62 is released. The slider 62 is moved downward by the elastic force of the reset spring 63, so that the splint 65 and the ball 64 restrict the sealing ring.

[0037] At this time, align the burr between the two groups of limiting plates 51, and then rotate the threaded rod 44 to drive the shift rod 41 to slide on the inner wall of the connecting block 3, so that the limiting plate 51 fits with the sealing ring, and then rotate the threaded rod 44 to make the shift rod 41 squeeze the compression spring 43. Through the elasticity of the compression spring 43, the shift rod 41 has a certain degree of mobility, thereby reducing the damage of the limiting plate 51 to the sealing ring.

[0038] At this time, the worker pulls the sealing ring steadily to make the sealing ring slide on the inner arc surface of the limiting plate 51, so that the trimming blade 52 trims the burrs. When the trimming blade 52 needs to be replaced, the restriction on the trimming blade 52 is released by turning the bolt 53, and then the trimming blade 52 is pulled upward to make the trimming blade 52 slide out from the inner wall of the shift rod 41. The new trimming blade 52 is then installed to complete the replacement of the trimming blade 52, which is simple and convenient.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
