Description

Technical Field

[0002] The rubber sealing ring trimming device is a device used for processing and trimming rubber sealing rings, which is used to trim burrs and burrs. Rubber sealing rings are widely used in various industrial fields to seal the interfaces of pipes, valves, pumps and other equipment to prevent leakage of liquids or gases.

[0003] Chinese Patent Authorization Announcement No.: CN217621742U provides a trimming device for a rubber sealing ring. The scheme preliminarily positions the rubber sealing ring through an annular groove, and rolls and presses the rubber sealing ring located in the annular groove through two symmetrically arranged rollers, so that the rubber sealing ring can be re-positioned, and the trimming of the rubber sealing ring is completed by the rolling of the rollers and the rotation of the trimming knife, which effectively improves the work efficiency. At the same time, the rolling and pressing of the rollers can avoid the deformation of the rubber sealing ring when the trimming knife is trimming, thereby improving the trimming quality.

[0004] Since factories produce rubber sealing rings of different specifications and diameters, the above scheme cannot fully tighten the sealing rings of different diameters when fixing them, which will cause uneven and inconsistent edges of the sealing rings after trimming, which will affect the fit between the sealing ring and the interface and reduce the sealing performance. Therefore, a rubber sealing ring trimming device is proposed to address the above problem. Utility Model Content

[0033] Example:

[0034] See also Figure 1-Figure 2 A rubber sealing ring trimming device comprises a shell 1, a mounting hole is provided at the top of the shell 1, a swivel 3 is rotatably connected to the inner wall of the mounting hole, a plurality of fixing components 2 distributed in an annular shape and equidistantly are arranged on the inner side of the swivel 3, an adjustment component 7 is arranged on the outer end of the fixing component 2, the fixing component 2 comprises a pair of fixing blocks 21 fixedly connected to the inner side of the swivel 3, a tensioning block 25 is provided between the pair of fixing blocks 21, a slider 24 is fixedly connected to the outer end of the tensioning block 25, the adjustment component 7 comprises a driving block 73, the driving block 73 matches the tensioning block 25, a plurality of slide grooves distributed in an annular shape and equidistantly are provided on the outer end of the driving block 73, and the slider 24 is slidably connected to the slide grooves.

[0035] The outer surrounding of the rotating ring 3 is fixedly connected with a gear ring 4, the inner wall of the housing 1 is fixedly connected with a motor 6, and the output end of the motor 6 is fixedly connected with a gear 5, which matches the gear ring 4 and is meshed with the gear ring 4.

[0036] The device in this scheme is mainly used to evenly tighten the sealing ring when trimming it. The sealing ring is set on the circular ring composed of multiple arc blocks 22. At this time, it is necessary to rotate the threaded rod 71, so that it moves upward to squeeze the tensioning block 25 and push the tensioning block 25 outward. At this time, the arc block 22 will also move outward, so that the arc block 22 can evenly tighten the sealing ring set thereon. At this time, the motor 6 can be started to drive the gear 5 to rotate. The outer end of the swivel 3 is fixed with a gear ring 4. At the same time, the swivel 3 is located in the mounting hole on the housing 1 and is rotatably connected to the inside of the mounting hole. The gear ring 4 is meshed with the gear 5. Therefore, the gear 5 can drive the swivel 3 to rotate, and the swivel 3 can drive the sealing ring set on the arc block 22 to rotate. At this time, it is necessary to set a trimming device such as a scraper on its outside. Through its rotation, the edge of the sealing ring can be trimmed to eliminate burrs on the edge of the sealing ring and make it smooth.

[0037] See also Figure 2-Figure 4 The top of the tensioning block 25 is fixedly connected to the arc block 22, and the tensioning block 25 and the arc block 22 are integrally formed.

[0038] The tensioning block 25 is fixedly connected to the limiting blocks 23 on both sides. The outer end of the fixing block 21 is provided with a limiting groove matching the limiting block 23 , and the limiting block 23 is slidably connected to the limiting groove.

[0039] The fixing assembly 2 in the present scheme is mainly composed of an arc block 22 and a tensioning block 25. Limiting blocks 23 for limiting are fixed on both sides of the tensioning block 25. The fixing block 21 is fixed on the inner side of the swivel 3. The limiting groove on the fixing block 21 is horizontal, so the limiting block 23 can drive the tensioning block 25 to move only horizontally. At the same time, a slider 24 is fixed to the front end of the tensioning block 25. The slider 24 is slidably connected to the slide groove on the driving block 73, so that it can move to the outer edge when it is squeezed by the driving block 73. Through the cooperation of multiple fixing assemblies 2, the sealing ring mounted on the arc block 22 can be tightened. The arc block 22 is wide at the top and narrow at the bottom, so that the sealing ring can be limited to the bottom when the sealing ring is tightened.

[0040] See also Figure 2-Figure 4 The adjustment component 7 also includes a threaded rod 71, a driving block 73 with a trapezoidal cross-section, a movable groove is opened inside the driving block 73, and a threaded hole connected to the movable groove is opened inside the driving block 73, the threaded hole matches the threaded rod 71, and the threaded rod 71 passes through the threaded groove.

[0041] A movable block 72 is fixedly connected to the top of the threaded rod 71 , and the movable block 72 is slidably connected to the movable groove.

[0042] The adjustment component 7 in the present scheme is mainly used to drive the fixing component 2. The driving block 73 is trapezoidal in shape and matches the tensioning block 25. The driving block 73 is provided with movable grooves and threaded holes that are interconnected. When the threaded rod 71 inside the driving block 73 rotates, the driving block 73 is pushed upward through the threaded connection with the threaded hole, thereby squeezing the tensioning block 25 and driving it. The movable block 72 on the threaded rod 71 slides in the movable groove, and the movable block 72 acts as a limiter to prevent the threaded rod 71 from dislocating.

[0043] Working principle: When using this device, first, the sealing ring is sleeved on the circular ring composed of multiple arc blocks 22. At this time, it is necessary to rotate the threaded rod 71. The driving block 73 is trapezoidal in shape and matches the tensioning block 25. The driving block 73 is provided with movable grooves and threaded holes that are interconnected, so that the tensioning block 25 can be squeezed and driven to push the tensioning block 25 outward. At this time, the arc block 22 will also move outward, so that the arc block 22 can evenly tighten the sealing ring sleeved thereon. At this time, the motor 6 can be started to drive the gear 5 to rotate, and the gear ring 4 is meshed with the gear 5. Therefore, the gear 5 can drive the swivel 3 to rotate, and the swivel 3 can drive the sealing ring sleeved on the arc block 22 to rotate. At this time, it is necessary to set a trimming device such as a scraper on its outside. Through its rotation, the edge of the sealing ring can be trimmed to eliminate burrs on the edge of the sealing ring and make it smooth.

[0044] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
