Technical Field

[0001] This utility model relates to the field of sealing ring production technology, specifically to a sealing ring trimming device. Background Technology

[0002] A sealing ring is an elastic ring-shaped part used to fill gaps at joints to prevent fluid or gas leakage. It is usually made of elastic material, and the choice of material is of great significance to its sealing performance and service life, because the performance of the material directly affects the performance of the sealing ring. During the production of sealing rings, trimming equipment is required to trim the burrs at the edges.

[0003] The existing edge trimming equipment for sealing rings involves first selecting a positioning table that matches the sealing ring, fixing the positioning table on the operating table, then aligning and installing the sealing ring with the positioning table, and then starting the cutting head to remove the burrs on the rubber ring fixed to the positioning table.

[0004] However, the existing positioning table has a fixed size. When processing sealing rings of different sizes, it is necessary to select a positioning table of the corresponding size for installation. When changing the positioning table, it is necessary to stop the machine for disassembly and installation, which reduces the trimming efficiency. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides a technical solution: such as Figure 1 - Figure 6 The device for trimming a sealing ring shown includes a machine base 1. A positioning table 2 is fixedly connected to one side of the machine base 1. A gear plate 3 is provided on the side of the positioning table 2 away from the machine base 1. A drive groove 4 is opened inside the gear plate 3. The drive groove 4 is arc-shaped and has multiple sets arranged in a circumferential array inside the gear plate 3. A slider 5 is slidably connected inside the drive groove 4. A slide rod 6 is fixedly connected to the end of the slider 5 away from the drive groove 4. The slide rod 6 is slidably connected to one side of the gear plate 3. A positioning plate 7 is fixedly connected to the slide rod 6 near the gear plate 3 at a position away from the slider 5. A drive assembly is provided on the outside of the gear plate 3.

[0022] Please see Figure 1 - Figure 6 The drive assembly shown in the figure includes a gear 10, which meshes with the outside of the gear disk 3. The gear 10 is rotatably connected to the positioning platform 2 on the side near the gear disk 3. A mounting plate 9 is slidably connected to the slide rod 6 on the side away from the gear disk 3. The mounting plate 9 is fixedly connected to the positioning platform 2 on the side near the gear disk 3.

[0023] Please see Figure 3 - Figure 6 In the diagram, a positioning block 8 is fixedly connected to the side of the mounting plate 9 near the toothed plate 3. There are multiple sets of positioning blocks 8 arranged in a circular array. The positioning blocks 8 are slidably connected to the side of the toothed plate 3 near the mounting plate 9. The mounting plate 9 is slidably connected between multiple sets of slide rods 6.

[0024] Please see Figure 3 - Figure 5 In the figure, a worm gear 11 is fixedly connected to the side of the gear 10 away from the positioning table 2. A worm wheel 12 is rotatably connected to the outside of the worm gear 11. A rotating knob 15 is fixedly connected to one side of the worm wheel 12. A support component is provided on the side of the worm wheel 12 away from the rotating knob 15.

[0025] Please see Figure 3 and Figure 5 The support assembly shown in the figure includes a support shaft 13, which is rotatably connected inside the worm gear 12 on the side away from the rotating knob 15. A support plate 14 is fixedly connected to the end of the support shaft 13 away from the worm gear 12. The support plate 14 is fixedly connected to the positioning table 2 on the side near the gear 10.

[0026] Please see Figure 1 and Figure 2 In the figure, the machine 1 is fixedly connected to the side of the positioning table 2 with an operating frame 16. The operating frame 16 is set in an inverted "L" shape, and the cutting head 17 is set on the side of the operating frame 16 near the toothed disc 3.

[0027] Working principle: First, the sealing ring is placed on the outside of the positioning plate 7. Then, the gear 10 is rotated, which drives the gear disk 3 to rotate. The gear disk 3 pushes the slider 5 through the drive groove 4, allowing the slider 5 to slide inside the drive groove 4. This allows the slider 5 to control the extension and retraction of the slide rod 6, which in turn controls the expansion or contraction of the positioning plate 7. Once the size of the sealing ring is adjusted to the appropriate size, the operating frame 16 on one side of the machine tool 1 is activated, allowing the operating frame 16 to control the cutting head 17 to cut the sealing ring.

[0028] When the slide rod 6 slides, to prevent it from deviating and failing to support the sealing ring at the correct angle, the sliding direction of the slide rod 6 can be restricted by the positioning block 8 to ensure the smoothness of the slide rod 6. The positioning block 8 is fixed by the mounting plate 9 to ensure that the slide rod 6 will not push the positioning block 8 to move when it slides. When it is necessary to rotate the gear 10, the operator can hold the rotating knob 15 and rotate the rotating knob 15 to drive the worm gear 12 to rotate on one side of the support shaft 13. The support shaft 13 is supported by the support plate 14 to ensure the stability of the worm gear 12 when it rotates. In this way, the rotation of the worm gear 12 can drive the worm 11 to rotate, thereby driving the gear 10 to rotate. The gear 10 controls the gear plate 3, thereby controlling the opening and closing of the slide rod 6 and the positioning plate 7.

[0029] It should be noted that this device allows the gear disk 3 to drive the slider 5 to slide via the drive groove 4, and the slider 5 controls the opening and closing of the slide rod 6 and the positioning plate 7, ensuring the compatibility of rubber rings with different inner and outer diameters. The connection method between the worm gear 12 and the worm 11 when the gear 10 controls the rotation of the gear disk 3 can prevent the gear 10 from reversing and causing the sealing ring to detach from the outside of the positioning plate 7, thereby improving the trimming efficiency of sealing rings with different inner and outer diameters.
