Description

Technical Field

[0001] This utility model relates to the field of sealing ring processing technology, specifically a device for removing flash from rubber sealing rings. Background Technology

[0002] Flash on a sealing ring refers to burrs, irregular protrusions, or excess material that appear on the edge of the sealing ring during production or use. Newly manufactured sealing rings need to have their flash removed.

[0003] In the prior art, patent announcement number CN218927270U discloses an O-ring flash removal device, including: a housing, a lighting lamp, a DC brushless motor and a rotating base; the DC brushless motor is fixedly installed inside the housing, and the rotating base is fixedly installed on the output shaft of the DC brushless motor extending out of the housing.

[0004] The aforementioned device rotates the O-ring via a rotating base, and then uses a grinding tool or knife to remove the burrs on the outer wall of the O-ring. Since the O-ring is fitted onto the rotating base, only the burrs on the outer side of the O-ring can be removed. Therefore, a burr removal device for rubber O-rings is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a device for removing flash from rubber sealing rings to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rubber sealing ring deflashing device, comprising a base, a device housing fixedly mounted on the base, a fixed rotating wheel rotatably mounted on the device housing, a movable rotating wheel movably mounted below the fixed rotating wheel, an O-ring seal provided between the fixed rotating wheel and the movable rotating wheel, a drive mechanism fixedly mounted on the device housing, the drive mechanism comprising a motor fixedly mounted on one side of the device housing and a positioning sleeve, a drive shaft fixedly mounted at the output end of the motor, and the end of the drive shaft fixedly mounted on the movable rotating wheel, and a cutting mechanism mounted on the device housing.

[0007] Preferably, the drive mechanism further includes a drive screw rotatably mounted in the positioning sleeve and a telescopic rod slidably mounted in the positioning sleeve. A screw nut is fixedly mounted on the upper end of the telescopic rod, and the screw nut is threaded onto the drive screw. Both the drive shaft and the drive screw are equipped with clutches, which can transmit the power of the drive motor to the drive shaft and the drive screw respectively. Helical gears are fixedly mounted on the output end of the motor and the upper end of the drive screw, and the helical gears mesh together in pairs. A lifting frame is fixedly mounted on the lower end of the telescopic rod, and a movable shaft is rotatably mounted on the lifting frame, with the end of the movable shaft fixedly mounted on the movable wheel.

[0008] Preferably, the equipment housing is equipped with a positioning frame, and the motor and the positioning sleeve are both fixedly installed on one side of the equipment housing through the positioning frame.

[0009] Preferably, the fixed rotating wheel is rotatably mounted on the equipment housing via a drive shaft, and the movable rotating wheel is movably mounted below the fixed rotating wheel via a movable shaft.

[0010] Preferably, the cutting mechanism includes an adjusting screw rotatably mounted inside the equipment housing and a sliding rod slidably mounted on the equipment housing. The adjusting screw has threads in opposite directions at both ends. An adjusting nut is threaded onto the adjusting screw, and the sliding rod is fixedly mounted on the adjusting nut. A blade holder is fixedly mounted at the end of the sliding rod, and a blade assembly is fixedly mounted on the blade holder. A handwheel is connected to the adjusting screw, and a planetary reducer is provided between the handwheel and the adjusting screw.

[0011] Preferably, the equipment housing has a sliding groove, and the sliding rod is slidably mounted on the equipment housing through the sliding groove.

[0012] Preferably, the tool holder is slidably mounted on the outside of the equipment housing via a sliding rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, a motor drives the adjusting screw to rotate, causing the adjusting nut to move downwards along the screw, which in turn causes the telescopic rod to extend, driving the lifting frame downwards. The descent of the lifting frame causes the moving wheel to move downwards, tensioning the O-ring between the moving and stationary wheels. After the O-ring is tensioned, the motor drives the stationary wheel to rotate, causing the O-ring to circulate. During the circulatory rotation of the O-ring, the blade assembly can quickly remove the flash from both the inner and outer sides of the O-ring.

[0015] 2. In this application, during the cyclic rotation of the O-ring, the adjusting screw can be rotated by operating the handwheel. The rotation of the adjusting screw drives the adjusting nuts to move closer or further apart. When the adjusting nuts move closer together, the blade assembly moves closer together, thereby completing the cutting action and gradually removing the excess portion on both the inner and outer sides of the sealing ring. In addition, the distance between the blade assemblies is adjustable, allowing for flexible removal of excess edges on sealing rings of different diameters. Attached Figure Description

[0022] 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.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a rubber sealing ring flash removal device, including a base 5, an equipment housing 1 fixedly installed on the base 5, a fixed rotating wheel 2 rotatably installed on the equipment housing 1, a movable rotating wheel 4 movably installed below the fixed rotating wheel 2, an O-ring seal 3 provided between the fixed rotating wheel 2 and the movable rotating wheel 4, a drive mechanism 6 fixedly installed on the equipment housing 1, and a cutting mechanism 7 installed on the equipment housing 1. By using the drive mechanism 6 and the cutting mechanism 7 in cooperation, the flash on both the inner and outer sides of the sealing ring can be quickly cut off.

[0024] like Figure 2 , Figure 3 and Figure 4As shown, the drive mechanism 6 includes a motor 601 and a positioning sleeve 605 fixedly installed on one side of the equipment housing 1. A drive shaft 603 is fixedly installed at the output end of the motor 601, and the end of the drive shaft 603 is fixedly installed on the rotating wheel 4. The drive mechanism 6 also includes a drive screw 608 rotatably installed inside the positioning sleeve 605 and a telescopic rod 606 slidably installed inside the positioning sleeve 605. A screw nut 607 is fixedly installed at the upper end of the telescopic rod 606, and the screw nut 607 is threaded onto the drive screw 608. Both the moving shaft 603 and the drive screw 608 are equipped with clutches 604. The output end of the motor 601 and the upper end of the drive screw 608 are both fixedly installed with helical gears 602, and the helical gears 602 mesh together in pairs. The lower end of the telescopic rod 606 is fixedly installed with a lifting frame 609. A movable shaft 610 is rotatably installed on the lifting frame 609, and the end of the movable shaft 610 is fixedly installed on the moving wheel 4. The equipment housing 1 is equipped with a positioning frame. The motor 601 and the positioning sleeve 605 are both fixedly installed on one side of the equipment housing 1 through the positioning frame.

[0025] Specifically, after the O-ring 3 is installed between the fixed rotating wheel 2 and the moving rotating wheel 4, the adjusting screw 703 is rotated by the motor 601, causing the adjusting nut 704 to move downward along the adjusting screw 703. The downward movement of the adjusting nut 704 causes the telescopic rod 606 to extend, which in turn drives the lifting frame 609 to move downward. The downward movement of the lifting frame 609 pushes the moving rotating wheel 4 downward, causing the O-ring 3 to be tensioned between the moving rotating wheel 4 and the fixed rotating wheel 2. After the O-ring 3 is tensioned between the two rotating wheels, the motor 601 can drive the fixed rotating wheel 2 to rotate, thereby causing the O-ring 3 to rotate cyclically. During the cyclic rotation of the O-ring 3, the blade assembly 702 can quickly remove the flash.

[0026] like Figure 2 and Figure 5 As shown, the cutting mechanism 7 includes an adjusting screw 703 rotatably mounted inside the equipment housing 1 and a sliding rod 705 slidably mounted on the equipment housing 1. The adjusting screw 703 has threads in opposite directions at both ends. An adjusting nut 704 is threaded onto the adjusting screw 703, and the sliding rod 705 is fixedly mounted on the adjusting nut 704. A blade holder 701 is fixedly mounted at the end of the sliding rod 705, and a blade assembly 702 is fixedly mounted on the blade holder 701. A handwheel 707 is connected to the adjusting screw 703, and a planetary reducer 706 is provided between the handwheel 707 and the adjusting screw 703. A sliding groove is provided on the equipment housing 1, and the sliding rod 705 is slidably mounted on the equipment housing 1 through the sliding groove.

[0027] Specifically, during the cyclic rotation of the O-ring 3, the handwheel 707 can be turned. Turning the handwheel 707 will cause the adjusting screw 703 to rotate accordingly. The rotation of the adjusting screw 703 will cause the adjusting nuts 704 to move closer or further apart. When the adjusting nuts 704 move closer together, the blade assembly 702 will move closer together, thus achieving the cutting action. The purpose of this action is to gradually remove the flash on both the inner and outer sides of the sealing ring, ensuring that the edge of the sealing ring is neat and flawless. Furthermore, the distance between the blade assemblies 702 is adjustable. This design flexibility allows the device to easily remove flash from sealing rings of different diameters, thus adapting to the processing needs of sealing rings of various sizes.

[0028] Working principle: In use, first place the O-ring 3 between the fixed wheel 2 and the moving wheel 4. Then, control the clutch 604 on the adjusting screw 703 to be engaged. When the clutch 604 on the adjusting screw 703 is engaged, the motor 601 drives the adjusting screw 703 to rotate, causing the adjusting nut 704 to move downward along the adjusting screw 703. When the adjusting nut 704 moves downward along the adjusting screw 703, the telescopic rod 606 will extend, thereby driving the lifting frame 609 to move downward. When the lifting frame 609 moves downward, it will drive the moving wheel 4 to move downward, thereby tensioning the O-ring 3 between the moving wheel 4 and the fixed wheel 2. After the O-ring 3 is tensioned between the moving wheel 4 and the fixed wheel 2, the motor 601 drives the fixed wheel 2 at the end of the drive shaft 603 to rotate. After the fixed wheel 2 rotates, it will drive the O-ring 3 to rotate cyclically. During the cyclic rotation of the O-ring 3, the blade assembly 702 can quickly cut off the flash. Furthermore, when the O-ring 3 rotates in a cycle, the handwheel 707 can be turned. After turning the handwheel 707, it will drive the adjusting screw 703 to rotate. After the adjusting screw 703 rotates, it will drive the adjusting nuts 704 to move closer or further apart. When the adjusting nuts 704 move closer together, they will drive the blade assembly 702 to move closer together, realizing the cutting action and gradually removing the flash on both sides of the sealing ring. The distance between the blade assembly 702 can be adjusted, which can easily remove the flash on sealing rings of different diameters.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
