[0015] like Figure 1-4 As shown, a burr trimming device for rubber seals includes a hollow base 1, a placement seat 2 rotatably connected to the top of the base 1, a rotating device for driving the placement seat 2 to rotate at the bottom, a placement groove 4 for placing seals inside the placement seat 2, a trimming knife 5 disposed above the placement seat 2, the trimming knife 5 being fixedly connected to the bottom of a trimming knife holder 6, the trimming knife holder 6 being mounted on a horizontal beam 7, a moving mechanism for driving the trimming knife holder to move left and right along the horizontal beam 7 being mounted on the horizontal beam 7, a lifting cylinder 8 being connected to the left end of the horizontal beam 7, and the fixed end of the lifting cylinder 8 being disposed on the front and rear moving device.

[0016] Specifically, place the seal 17 that needs repair into the placement groove 4, such as... Figure 4 As shown, the top of the seal has burrs around its circumference. The seal is made of rubber, which has a certain elasticity. The outer diameter of the sealing ring is slightly larger than the diameter of the placement groove 4, so that the seal 17 can be located in the placement groove 4. The lifting cylinder 8 starts and moves its free end downward, so that the tip of the trimming knife 5 corresponds to the position of the seal that needs to be trimmed. The rotating device starts and drives the placement seat 2 to rotate, and the trimming knife 5 cuts off the excess burrs.

[0017] The bottom of the lifting cylinder 8 is fixedly connected to the top of the slider 12, and the slider 12 is slidably mounted on the linear guide rail 13.

[0018] Specifically, the lifting cylinder 8 drives the trimming blade 5 to rise and fall, thereby adjusting the distance between the trimming blade 5 and the seal 17.

[0019] The top two ends of the linear guide rail 13 are fixedly connected to baffles 14, which are fixedly connected to the top of the top plate of the base 1. One end of the baffle 14 is fixedly connected to a horizontally arranged movable cylinder 15, the free end of the movable cylinder 15 is fixedly connected to the top of the linear guide rail 13, and the free end of the movable cylinder 15 is fixedly connected to one side of the slider 12.

[0020] Specifically, the free end of the movable cylinder 15 extends and retracts, causing the slider 1 to move horizontally along the linear guide rail 13, thereby realizing the back-and-forth movement of the trimming tool 5.

[0021] The longitudinal section of the dressing tool holder 6 is a U-shaped structure. The dressing tool holder 6 is slidably mounted on the horizontal beam 7 and is fixed to the horizontal beam 7 by fixing bolts 16.

[0022] Specifically, when the left and right positions of the trimming blade 5 need to be adjusted, loosen the fixing bolt 16 to allow the trimming blade holder 6 to move along the horizontal beam 7, thereby achieving left and right movement.

[0023] The rotating device includes a housing 9, which is fixedly connected to the top of the placement seat 2. A driven gear ring 10 is installed inside the housing 9. The driven gear ring 10 meshes with a driving gear 11. The driving gear 11 is mounted on the drive shaft of a drive motor 19. The drive motor 19 is mounted on the bottom of the top plate of the placement seat 2. A connecting sleeve 18 is fixedly connected to the inner side of the driven gear ring 10. A rotating disk 3 is fixedly connected to the top of the connecting sleeve 18. The connecting sleeve 18 extends upward to the outside of the housing 9. The placement seat 2 is fixedly connected to the top of the rotating disk 3.

[0024] Specifically, the drive motor 19 starts, causing the drive gear 11 to rotate. The driven gear ring 10, which meshes with the drive gear, rotates, causing the connecting sleeve 18 and the rotating disk 3 to rotate, thereby causing the placement seat 2 to rotate.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
