Description

Technical Field

[0001] This utility model relates to the field of rubber ring production, specifically a rubber ring burr removal device. Background Technology

[0002] Rubber rings are ring-shaped components made of rubber, commonly used for sealing, pressure reduction, and cushioning. They possess good elasticity and wear resistance, allowing them to fit tightly against connections in pipes, bearings, and other joints, effectively preventing liquid or gas leakage while also blocking the intrusion of external dust and dirt. Rubber rings can be further classified according to their material, such as natural rubber rings, butyl rubber rings, and fluororubber rings. Each type of rubber ring is suitable for different working environments due to its unique material properties. In general, rubber rings are indispensable sealing components in industrial production and daily life. After production, rubber rings require deburring devices to remove burrs.

A rotating rod is rotatably connected to the center of the lower inner wall of the hollow cylinder, and the top end of the rotating rod extends upward through the upper end wall of the hollow cylinder. A matching bearing is installed at the connection between the upper end wall of the hollow cylinder and the rotating rod. Multiple sets of evenly distributed arc-shaped tensioning strips are provided on the outer side of the hollow cylinder. This invention can collect the rubber burrs generated during cutting, preventing waste from scattering everywhere. It can tension rubber rings of different specifications without changing the tensioning device repeatedly, and it can cut rubber ring burrs of different specifications without changing the cutting device repeatedly.

[0004] However, the method of tightening the rubber ring with an arc-shaped support strip in the above technology is prone to deformation of the rubber ring, making the circular cutter inaccurate in removing the burrs from the rubber ring, and thus damaging the rubber ring; therefore, the market urgently needs to develop a rubber ring burr removal device to help people solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a rubber ring burr removal device to solve the problem mentioned in the background art that the method of tightening the rubber ring by the arc-shaped support strip easily leads to deformation of the rubber ring, making the circular cutter inaccurate in removing the burrs of the rubber ring, and thus damaging the rubber ring.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rubber ring burr removal device, comprising a placement platform, a positioning disc connected to the middle of the upper end of the placement platform, a rubber ring fitted and connected to the outer side of the positioning disc, an L-shaped support frame fixedly connected to the middle of the rear end of the placement platform, a hydraulic rod fixedly connected to the front end of the upper end of the L-shaped support frame, a fixed plate connected to the upper inner side of the L-shaped support frame, a movable plate connected to the lower end of the fixed plate, and an annular cutter connected to the middle of the lower end of the movable plate.

[0007] Preferably, a threaded hole is provided in the middle of the upper surface of the placement platform, and the positioning disc and the placement platform are fixed by a first bolt passing through the middle of the positioning disc and inserted into the threaded hole.

[0008] Preferably, the lower end of the hydraulic rod telescopic end passes through the placement platform and is fixedly connected to the middle of the upper end of the fixed plate. Guide rods are fixedly connected to both the front and rear ends of the middle of the upper end of the fixed plate. Guide holes are provided inside the upper end of the L-shaped support frame and at both the front and rear ends of the hydraulic rod.

[0009] Preferably, the upper ends of the two guide rods pass through the interior of the two guide holes and extend out of the upper surface of the L-shaped support frame.

[0010] Preferably, the front and rear ends of both sides of the upper surface of the movable plate are fixedly connected with connecting posts, and the upper ends of the four connecting posts pass through the interior of the fixed plate and extend out of the upper surface of the fixed plate, and are fixedly connected with limiting pieces.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a rubber ring burr removal device, including a placement platform 1. A positioning disc 102 is connected to the middle of the upper end of the placement platform 1. A rubber ring 2 is fitted and connected to the outer side of the positioning disc 102. The inner diameter of the rubber ring 2 matches the outer diameter of the positioning disc 102. The positioning disc 102 is used to position the rubber ring 2. A threaded hole 101 is provided in the middle of the upper end face of the placement platform 1. The positioning disc 102 and the placement platform 1 are connected and fixed by a first bolt 103 passing through the middle of the positioning disc 102 and inserted into the threaded hole 101. By removing the first bolt 103, the positioning disc 102 of different diameters can be replaced according to the rubber ring 2 that needs to be deburred, so as to achieve the positioning of different rubber rings 2.

[0024] Please see Figure 1-3An L-shaped support frame 3 is fixedly connected to the middle of the rear end of the placement platform 1. A hydraulic rod 301 is fixedly connected to the front end of the upper end of the L-shaped support frame 3. A fixed plate 4 is connected to the upper inner side of the L-shaped support frame 3. The lower end of the telescopic end of the hydraulic rod 301 passes through the placement platform 1 and is fixedly connected to the middle of the upper end of the fixed plate 4. Guide rods 401 are fixedly connected to both the front and rear ends of the middle of the upper surface of the fixed plate 4. Guide holes 302 are provided inside the upper end of the L-shaped support frame 3 and at both the front and rear ends of the hydraulic rod 301. The upper ends of the two guide rods 401 pass through the two guide holes 302 respectively and extend out of the upper surface of the L-shaped support frame 3. The fixed plate 4 is raised and lowered by the hydraulic rod 301. When the fixed plate 4 is raised and lowered, the guide rods 401 are simultaneously guided to slide along the guide holes 302. A movable plate 5 is connected to the lower end of the fixed plate 4. A ring cutter 6 is connected to the middle of the lower end of the movable plate 5. Connecting columns 501 are fixedly connected to both the front and rear ends of the upper surface of the movable plate 5. The upper end of the 01 passes through the interior of the fixed plate 4 and extends out of the upper surface of the fixed plate 4, and is fixedly connected to the limiting piece 502. Springs 503 are provided between the fixed plate 4 and the movable plate 5 and on the outside of the four connecting posts 501. The upper end of the annular cutter 6 is fixedly connected to the connecting round plate 601. The middle part of the connecting round plate 601 is fixedly connected to the middle part of the movable plate 5 by the second bolt 602. The annular cutter 6 can be separated from the movable plate 5 by removing the second bolt 602, which makes it easy to replace different matching annular cutters 6 according to different outer diameters of rubber rings 2. When the fixed plate 4 descends, it drives the movable plate 5 to descend, which in turn drives the annular cutter 6 to descend. After the annular cutter 6 descends, it fits into the outside of the rubber ring 2. At this time, the descent of the annular cutter 6 is blocked. When the fixed plate 4 continues to descend, it compresses the spring 503. The restoring force of the spring 503 presses down the movable plate 5, which in turn presses down the annular cutter 6, so that the annular cutter 6 can remove the burrs on the outside of the rubber ring 2.

[0025] Working Principle: In use, first, the rubber ring 2 to be processed is fitted onto the outside of the positioning disc 102, which is installed and fixed on the placement platform 1, ensuring a tight fit between the inner diameter of the rubber ring 2 and the outer diameter of the positioning disc 102 for stable positioning. Then, the hydraulic rod 301 is activated. The telescopic end of the hydraulic rod 301 pushes the fixed plate 4 downwards along the L-shaped support frame 3. Simultaneously, the fixed plate 4, through the cooperation of the guide rod 401 and the guide hole 302, ensures a smooth and vertical descent. As the fixed plate 4 descends, the movable plate 5 descends accordingly, and the annular cutter 6 at its lower end gradually approaches and fits onto the outside of the rubber ring 2. When the annular cutter 6 encounters resistance from the rubber ring 2, the fixed plate 4 continues to descend. At this time, the spring 503 begins to compress, using its restoring force to apply additional downward pressure to the movable plate 5 and the annular cutter 6, ensuring that the annular cutter 6 can tightly fit against the outside of the rubber ring 2 and effectively remove burrs. After the burr removal is completed, the hydraulic rod 301 retracts, causing the fixed plate 4 and the movable plate 5 to rise. The spring 503 gradually returns to its original shape, and the annular cutter 6 separates from the rubber ring 2, completing one burr removal operation.

[0026] 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
