Description

Technical Field

[0001] This utility model relates to the field of fluororubber sealing ring processing technology, and in particular to a fluororubber sealing ring burr removal device. Background Technology

[0002] Due to their extremely high hardness, difficulty in low-temperature embrittlement, and susceptibility to damage during processing, fluororubber sealing rings require expensive specialized equipment such as high-temperature preheating and cryogenic trimming machines for burr removal, with strict process control. In existing technologies, the sealing rings are typically placed directly into a parts basket within a cryogenic trimming machine, causing them to accumulate. Shot is then sprayed into the basket, allowing the shot to contact the sealing rings and remove their burrs. However, in practical applications, the sealing rings are often scattered and randomly piled up in the basket, making it difficult for obscured rings to fully contact the shot, resulting in incomplete burr removal and hindering practical application. Therefore, we propose a fluororubber sealing ring burr removal device. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a device for removing burrs from fluororubber sealing rings.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A device for removing burrs from fluororubber sealing rings is designed, comprising a chassis with a processing chamber inside. One end of the processing chamber has a conveying port, and the other end is connected to a liquid nitrogen pipe with a valve installed above it. A projectile wheel is provided on the side of the liquid nitrogen pipe, and a parts cylinder with a drive shaft fixed at its bottom is provided below the liquid nitrogen pipe. A vibrating screen is connected below the processing chamber. The chassis also has a shot chamber that is connected to the projectile wheel and the vibrating screen respectively. A servo-driven turntable is installed inside the parts cylinder. Support rods are evenly fixed on the turntable. A discharge port is opened on one side of the parts cylinder. A spreading assembly is provided on the support rod. The spreading assembly includes a sleeve fitted on the support rod. Multiple sets of adjusting cylinders are equidistantly arranged on the sleeve. The end of the adjusting cylinder has a mounting groove.

[0005] In the above scheme, the processing chamber is provided with an output port that is connected to the discharge port of the projectile wheel.

[0006] In the above scheme, a door is hinged to the outside of the conveying port, a magnetic block one is fixed to the inner wall of the door, and a magnetic block two with the opposite magnetic properties to the magnetic block one is fixed to the outer wall of the chassis.

[0007] In the above scheme, the top of the chassis is connected to an exhaust pipe that communicates with the processing chamber, and a second valve is installed on the exhaust pipe.

[0008] In the above scheme, the processing chamber is provided with an output port that communicates with the discharge port of the projectile wheel. One end of the shot chamber is connected to the feed port of the projectile wheel through a conveying pipe, and the other end is connected to the vibrating screen through a recovery pipe.

[0009] In the above scheme, the discharge port of the vibrating screen is connected to a discharge pipe that extends out of the machine box.

[0010] In the above scheme, a connecting rod that is elastically connected to the adjusting cylinder is horizontally fixed on the sleeve, the sleeve is locked to the connecting rod by fastening screws, an elastic locking block is provided at the bottom end of the sleeve, and a slot that cooperates with the elastic locking block is opened on the surface of the turntable.

[0011] In the above scheme, a ball bearing is movably installed in the mounting groove.

[0012] The advantages and beneficial effects of this utility model are as follows: By setting up a processing chamber, a parts cylinder, a liquid nitrogen pipe, a blasting wheel, a vibrating screen, a shot hopper, and a chamber door, the parts cylinder can be switched between loading, processing, and unloading states by rotating it. Then, in conjunction with the liquid nitrogen pipe, the sealing rings inside the parts cylinder are subjected to low-temperature embrittlement. The shot hopper stores the shot, and the blasting wheel propels the shot from the shot hopper into the parts cylinder, thereby removing burrs from the sealing rings inside the parts cylinder. Compared with existing technologies, the chamber door seals the processing chamber, preventing dust and other impurities from outside the processing chamber from entering and affecting the burr removal effect. The addition of a turntable further enhances the benefits. The system consists of a support rod, a mounting groove, a sleeve, and an adjusting cylinder. By placing the sealing ring to be processed into the mounting groove, the sealing ring is opened and connected to the adjusting cylinder, preventing the sealing rings from being squeezed and overlapping. Compared with existing technologies, this not only allows the shot to fully contact the sealing ring, but also allows the contact position between the sealing ring and the shot to be adjusted using a turntable, thereby thoroughly removing the burrs from the sealing ring and improving the processing effect. By setting a connecting rod, fastening screw, and adjusting cylinder, the length of the exposed connecting rod can be adjusted by pulling the adjusting cylinder left and right, thereby adjusting the distance between the adjusting cylinder and the sleeve to accommodate sealing rings of different diameters, expanding the application range and making it more flexible to use.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a fluororubber sealing ring burr removal device, including a machine box 1 with a processing chamber 2 inside, a conveying port 21 at one end of the processing chamber 2, through which the parts cylinder 3 (hereinafter referred to as the part cylinder 3) is loaded and unloaded, and a liquid nitrogen pipe 17 with a valve 18 is connected to the upper part of the other end of the processing chamber 2, which is used to supply liquid nitrogen to the parts cylinder 3 in the processing chamber 2 to make the sealing ring brittle at low temperature so as to carry out subsequent burr removal operations; Furthermore, a door 22 is hinged to the outside of the conveying port 21. A magnetic block 23 is fixed to the inner wall of the door 22, and a magnetic block 24 with the opposite magnetic properties to the magnetic block 23 is fixed to the outer wall of the housing 1. The magnetic force between the magnetic block 23 and the magnetic block 24 makes the door 22 and the housing 1 stably closed and easy to open. Furthermore, the top of the chassis 1 is connected to an exhaust pipe 19 that communicates with the processing chamber 2. A valve 20 is installed on the exhaust pipe 19. By controlling the opening and closing of the valve 20, the gas in the processing chamber 2 is controlled to be discharged. A projectile wheel 26 is provided on the side of the liquid nitrogen tube 17, and the projectile wheel 26 is installed on the outer wall of the processing chamber 2; Furthermore, the processing chamber 2 is provided with an output port 27 that communicates with the discharge port of the projectile wheel 26 so as to spray projectiles into the parts cylinder 3; Below the liquid nitrogen tube 17 is a parts cylinder 3 with a drive shaft 4 fixed at the bottom. The drive shaft 4 is connected to a servo motor outside the chassis 1 and is used to drive the parts cylinder 3 to rotate left and right. Below the processing chamber 2 is a vibrating screen 25. The feed inlet of the processing chamber 2 and the vibrating screen 25 are connected through a connecting pipe, so that the impurities and shot removed by the sealing ring fall downward into the vibrating screen 25. Furthermore, the discharge port of the vibrating screen 25 is connected to a discharge pipe 8 that extends out of the casing 1. The vibrating screen 25 is equipped with two layers of screens. The first layer of screens allows shot to pass through, while the second layer of screens does not. Two discharge pipes 8 are provided. The first discharge pipe 8 from top to bottom is connected to the space above the first layer of screens, and the second discharge pipe 8 from top to bottom is connected to the space below the second layer of screens. The discharge pipes 8 are used to discharge waste materials such as burrs removed from the sealing ring. The casing 1 is also equipped with a shot magazine 28 that is connected to the projectile wheel 26 and the vibrating screen 25 respectively; Furthermore, the processing chamber 2 is provided with an output port 27 that is connected to the discharge port of the projectile wheel 26. One end of the shot chamber 28 is connected to the feed port of the projectile wheel 26 through the conveying pipe 29, and the other end is connected to the vibrating screen 25 through the recovery pipe 30. After the projectile wheel 26 is started, it sucks the shot in the shot chamber 28 upward and then sprays it into the parts cylinder 3 from the output port 27. A servo-driven turntable 5 is installed inside the parts cylinder 3. A servo motor 2 is installed at the bottom of the parts cylinder 3. The servo motor 2 is connected to the turntable 5 and provides power to the turntable 5 to make it rotate. Guide blocks are evenly provided on the edge of the turntable 5. The inner wall of the parts cylinder 3 is provided with sliding grooves that cooperate with the guide blocks to improve the stability of the turntable 5. Support rods 7 are evenly fixed on the turntable 5. A circle is drawn with the center of the turntable 5 as the center and a distance smaller than the radius of the turntable 5 as the radius. The support rods 7 are equidistant along the trajectory of the circle. A discharge port 16 is opened on one side of the parts cylinder 3 for discharging the shot and removing the burr waste. Specifically, by setting up a processing chamber 2, a parts cylinder 3, a liquid nitrogen pipe 17, a projectile wheel 26, a vibrating screen 25, a shot chamber 28, and a chamber door 22, the parts cylinder 3 is rotated to switch between loading, processing, and unloading states. Then, in conjunction with the liquid nitrogen pipe 17, the sealing rings inside the parts cylinder 3 are subjected to low-temperature embrittlement. In conjunction with the shot chamber 28, shot is stored. The projectile wheel 26 is used to spray the shot from the shot chamber 28 into the parts cylinder 3, thereby removing burrs from the sealing rings inside the parts cylinder 3. Compared with the prior art, the use of the chamber door 22 to seal the processing chamber 2 prevents dust and other impurities outside the machine box 1 from entering the processing chamber 2 during processing and affecting the burr removal effect.

[0018] The support rod 7 is equipped with a spreading assembly, which includes a sleeve 6 fitted onto the support rod 7. Multiple sets of adjusting cylinders 12 are equidistantly mounted on the sleeve 6. Each adjusting cylinder 12 has a mounting groove 14 at its end furthest from the sleeve 6. Figure 5 As shown, the end of the adjusting cylinder 12 is in the shape of an inverted "C" to prevent the sealing ring from coming off the mounting groove 14; Furthermore, a ball bearing 15 is movably installed in the mounting groove 14. The ball bearing 15 converts the friction between the mounting groove 14 and the sealing ring into rolling friction, thereby reducing the wear of the sealing ring. Specifically, by setting up a turntable 5, support rod 7, mounting groove 14, sleeve 6, and adjusting cylinder 12, the sealing ring to be processed is placed inside the mounting groove 14, which expands the sealing ring and connects it with the adjusting cylinder 12, preventing the sealing rings from being squeezed and overlapping. Compared with the prior art, this not only allows the shot to fully contact the sealing ring, but also allows the turntable 5 to adjust the contact position between the sealing ring and the shot, thereby thoroughly removing the burrs from the sealing ring and improving the processing effect.

[0019] Furthermore, a connecting rod 11 that is elastically connected to the adjusting cylinder 12 is horizontally fixed on the sleeve 6, and the connecting rod 11 is slidably connected to the inner wall of the adjusting cylinder 12. The sleeve 6 is locked to the connecting rod 11 by fastening screws 13 so as to adjust the relative position of the adjusting cylinder 12 and the connecting rod 11. An elastic block 9 is fixedly provided at the bottom end of the sleeve 6, and a slot 10 that cooperates with the elastic block 9 is opened on the surface of the turntable 5. The sleeve 6 and the turntable 5 are connected by elastic assembly, which is convenient for disassembly and assembly. Specifically, by setting up a connecting rod 11, a fastening screw 13, and an adjusting cylinder 12, the length of the exposed part of the connecting rod 11 can be adjusted by pulling the adjusting cylinder 12 left and right, thereby adjusting the distance between the adjusting cylinder 12 and the sleeve 6, so as to accommodate sealing rings of different diameters, expand the application range, and make the use more flexible.
