Description

Technical Field

[0001] This utility model relates to the field of rubber ring processing technology, and in particular to a device for grinding the burrs of rubber O-rings. Background Technology

[0002] During the molding and vulcanization process of rubber O-rings, due to the unavoidable microscopic gaps on the mold parting surface, the high-temperature and high-pressure rubber material will overflow, thus forming a thin layer of flash (or burr) at the parting line of the O-ring body. To ensure production quality, the flash is usually ground down.

[0003] Traditional polishing operations rely on manual labor, with operators manually trimming edges using polishing tools. This is labor-intensive, and fatigue can easily lead to decreased efficiency and compromised production quality due to prolonged repetitive work. On the other hand, using highly flexible automated robotic polishing units would be extremely costly and would not meet production demands. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rubber O-ring edge polishing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rubber O-ring flash polishing device includes a base, a slider is installed on one side of the upper part of the base by a limiting block, the slider is driven to move laterally by a screw, a feeding cylinder is rotatably installed on the upper part of the slider, a pressure plate is limited and installed on the top of the feeding cylinder, a pressing cover is provided in the middle of the pressure plate, the pressing cover is connected to a rotating support by a spring, and the rotating support is rotatably installed on the top of the connecting column in the middle of the feeding cylinder. An electric grinding roller is installed on the side away from the feeding cylinder.

[0006] In addition, a preferred structure is that the limiting block has a slot in the middle for mounting the slider, and the slider moves horizontally in a straight line through the limiting block.

[0007] In addition, a preferred structure is that a lead screw is rotatably installed on the middle of one side of the limiting block, and one end of the lead screw is threaded and extends into the interior of the limiting block and is screwed to the middle of the slider.

[0008] In addition, a preferred structure is that the main body of the pressure plate is circular and has multiple pressure strips on its side, with the pressure strips being installed in a limiting groove opened in the upper part of the feeding cylinder.

[0009] Furthermore, a preferred configuration is that, in its natural state, the pressure strip extends out of the limiting groove.

[0010] In addition, a preferred structure is that a rotating support is rotatably mounted on the top of the connecting column, and the rotating support is connected to the pressure cover by a spring.

The pressing cover is used to press the pressure plate, and the pressure plate has a through groove in the middle that matches the shape of the pressing cover.

[0012] The beneficial effects of this utility model are as follows: In this invention, the operator only needs to load the material onto the feeding cylinder to complete the loading operation, and can quickly limit the material by lifting and pressing the cover. There is no need to directly participate in the actual grinding process.

[0015] 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.

[0016] Reference Figure 1-5 A rubber O-ring flash polishing device includes a base 1. A slider 3 is installed on one side of the upper part of the base 1 via a limiting block 2. The slider 3 is driven to move laterally by a lead screw 21. A feeding cylinder 5 is rotatably installed on the upper part of the slider 3. A pressure plate 8 is limited and installed on the top of the feeding cylinder 5. A pressing cover 52 is provided in the middle of the pressure plate 8. The pressing cover 52 is connected to a rotating support 7 through a spring 6. The rotating support 7 is rotatably installed on the top of the connecting column 53 in the middle of the feeding cylinder 5. An electric grinding roller 4 is installed on the side away from the feeding cylinder 5. The electric grinding roller 4 includes a mounting bracket, a motor, and a grinding roller. The motor is mounted on the base 1 by the mounting bracket, and the grinding function is achieved by driving the grinding roller and the motor. This is easy to understand and will not be explained further.

[0017] A baffle 9 is installed at the bottom of the feeding cylinder 5 to support the rubber O-ring.

[0018] The limiting block 2 has a slot in the middle for mounting the slider 3, and the slider 3 moves horizontally in a straight line through the limiting block 2.

[0019] A lead screw 21 is rotatably mounted on the middle of one side of the limiting block 2. One end of the lead screw 21 is threaded and extends into the limiting block 2 and is screwed to the middle of the slider 3.

[0020] The main body of the pressure plate 8 is circular and has multiple pressure strips 81 on its side. The pressure strips 81 are installed in the limiting groove 51 opened on the upper part of the feeding cylinder 5.

[0021] In its natural state, the pressure strip 81 extends out of the limiting groove 51.

[0022] A rotating support 7 is rotatably mounted on the top of the connecting column 53, and the rotating support 7 is connected to the clamping cover 52 by a spring 6.

[0023] The main body of the clamping cover 52 is cylindrical, and a pair of protruding protrusions are provided on the outside. The clamping cover 52 is used to clamp the pressure plate 8. The middle part of the pressure plate 8 is provided with a through groove 82 that matches the shape of the clamping cover 52.

[0024] In this embodiment, rubber O-rings are sequentially fitted onto the feeding cylinder 5 until the last rubber O-ring reaches the position of the limiting groove 51. At this point, it indicates that the material is about to overflow, and the feeding is completed. Then, the pressure strip 81 of the pressure plate 8 is aligned with the limiting groove 51 at the top of the feeding cylinder 5 and inserted, so that the pressure plate 8 is installed on the feeding cylinder 5. During this process, the pressure plate 8 is installed by passing through the through groove 82 in its middle through the pressure cover 52. Then, the operator manually lifts the pressure cover 52 so that its bottom end is higher than the top surface of the pressure plate 8, and rotates the pressure cover 52 appropriately so that the protrusions on both sides are staggered with the through groove 82. Then, the pressure cover 52 is lowered. Under the reset action of the spring 6, the pressure cover 52 is appropriately pressed on the pressure plate 8. The pressure plate 8 simultaneously applies pressure to the rubber O-ring fitted below, and works with the baffle 9 to realize the top and bottom limit function of the rubber O-ring, so as to prevent the rubber O-ring from flying out during the grinding process. At this time, the rotating screw 21 drives the slider 3 to move through the thread transmission. The slider 3 simultaneously drives the upper material cylinder 5 to move until the rubber O-ring contacts the roller body of the electric grinding roller, thereby realizing rolling grinding.

[0025] At this time, rotating the lead screw 21 drives the slider 3 to move through the threaded transmission. The slider 3 synchronously drives the upper cylinder 5 to move until the rubber O-ring contacts the roller body of the electric grinding roller 4, thereby realizing rolling grinding.

[0026] During the grinding process, the electric grinding roller 4 rotates and maintains proper contact with the flash of the rubber ring. The friction generated attempts to drive the rubber ring to rotate as a whole. However, the feeding cylinder 5 and the inner wall of the rubber ring cannot provide enough static friction to ensure torque transmission. The contact surface between the rubber ring and the feeding cylinder 5 cannot achieve synchronous rigid transmission due to insufficient friction, which inevitably leads to relative sliding between the two, i.e., differential transmission or slippage. Therefore, the rubber ring is in a dynamic motion of free rotation or mismatched speed relative to the feed cylinder 5. This motion state ensures that the outer rough edge surface of the rubber ring can continuously exchange contact positions with the grinding roller 4. Furthermore, the rubber ring and the externally driven grinding roller 4 cannot maintain speed synchronization, thus achieving relative motion, which creates the conditions for the burrs to be removed.

[0027] It should be noted that the lead screw 21 and the grinding area where the electric grinding roller 4 is located maintain a certain safe distance, which makes the probability of the debris generated during the grinding process falling onto the surface of the lead screw 21 extremely low, effectively reducing the risk of the transmission mechanism being contaminated. In addition, a protective sleeve can be added to the outside of the lead screw 21 to further improve the protective effect. This sleeve can be directly purchased and used from the market. This is based on the conventional knowledge and common operation of those skilled in the art, and will not be explained further.

[0028] Compared to traditional grinding methods, in this invention, the operator only needs to complete the feeding operation and does not need to directly participate in the actual grinding process. The entire grinding operation is automatically completed through the coordinated movement of the electric grinding roller 4 and the feeding cylinder 5. This not only improves the convenience and reliability of the grinding operation, but also simplifies the overall structure of the device and can meet production needs.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
