Description

Technical Field

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

[0002] To ensure sealing performance under harsh environments and operating conditions, high precision is required for O-rings. Therefore, these O-rings need to undergo a burr removal process, which involves polishing to make their surface smooth.

[0003] A search revealed that the utility model patent with authorization announcement number CN221474608U discloses an O-ring burr removal device, which can quickly clamp and fix rubber rings of different diameters without replacing the fixing components, thereby improving the work efficiency and effectiveness of workers grinding O-rings.

[0004] Although the above-mentioned device can fix rubber sealing rings of different diameters for subsequent grinding and deburring operations, the travel distance required for grinding rubber sealing rings of different diameters is different. The above-mentioned device can only rely on manual adjustment of the travel distance. In actual grinding, over-grinding or incomplete removal of burrs is likely to occur, resulting in a high defect rate and making it too inconvenient to use.

[0005] Therefore, it is necessary to invent a device for removing burrs from O-ring rubber seals to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an O-ring burr removal device. Depending on the type of positioning pin used with the O-ring, a positioning pin is inserted into the corresponding positioning slot. This pin limits the movement of the O-ring positioning mechanism when the moving seat moves it to the left, preventing excessive or incomplete movement of the O-ring through the positioning mechanism. This ensures effective burr removal, higher processing efficiency, and reduced defect rate. It is also more convenient to use, addressing the problem in the background art where different travel distances are required for grinding rubber rings of different diameters. The existing equipment relies on manual adjustment of this distance, leading to over-grinding or incomplete burr removal, resulting in a high defect rate and inconvenience in actual use.

[0007] According to one aspect of this disclosure, the following technical solution is provided: an O-ring rubber seal burr removal device, comprising:

[0008] A burr removal mechanism is used to grind and remove burrs from O-rings of different specifications.

[0009] A positioning and moving mechanism includes two parallel T-shaped guide rails, both of which are fixedly mounted on the top of the worktable. A movable seat is slidably fitted onto the top of both T-shaped guide rails. Multiple positioning slots are evenly distributed on the left side of the top of each T-shaped guide rail. A chip removal groove extending to the front and back of the T-shaped guide rail is formed on the inner side of each positioning slot. A positioning pin is inserted into the inner side of each positioning slot.

[0010] A sealing ring positioning mechanism is used to support and position O-rings of different specifications.

[0011] According to at least one embodiment of the O-ring rubber seal burr removal device of the present disclosure, a handle is fixedly provided on the front of the movable seat, and a reinforcing magnet is fixedly provided at the bottom end of the positioning pin, and the reinforcing magnet is magnetically attracted to the adjacent T-shaped guide rail.

[0012] According to at least one embodiment of the present disclosure, an O-ring rubber seal burr removal device includes a worktable, a fixed frame is fixedly disposed on the top left side of the worktable, a rotating shaft is rotatably nested on the bottom right side of the fixed frame via a bearing, and a motor is fixedly disposed on the top of the fixed frame and is drively connected to the rotating shaft.

[0013] According to at least one embodiment of the O-ring rubber seal burr removal device of the present disclosure, a plurality of grinding wheels of different specifications are sequentially sleeved on the outer side of the rotating shaft from top to bottom. The outer side of the rotating shaft is provided with external threads, and two locking nuts are sleeved on the outer side of the rotating shaft through the external threads. The two locking nuts are respectively locked by the top of the plurality of grinding wheels and the bottom of the plurality of grinding wheels.

[0014] According to at least one embodiment of the present disclosure, the O-ring rubber seal burr removal device includes a seal positioning mechanism comprising a rotating seat rotatably nested on the top plate of a movable seat via a bearing, wherein a plurality of protrusions are uniformly fixedly disposed on the outer side of the rotating seat.

[0015] According to at least one embodiment of the O-ring rubber seal burr removal device of the present disclosure, the rotating seat top plate is fixedly provided with a plurality of positioning posts arranged coaxially in the vertical direction from bottom to top, and any one of the positioning posts is adapted to a grinding wheel that is collinear in the horizontal direction.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features a positioning and moving mechanism. This mechanism allows a positioning pin to be inserted into a positioning slot that matches the positioning post. A handle then drives the moving seat to move left along a T-shaped guide rail until the moving seat contacts the positioning pin, which then blocks the moving seat. During this process, the moving seat, through the sealing ring positioning mechanism, simultaneously moves the O-ring rubber seal to the burr removal station. At this point, driven by a motor, a rotating shaft drives multiple grinding wheels to rotate continuously. The grinding wheels that match the positioning post grind the O-ring rubber seal fixed to the outside of the positioning post, thus removing the burrs from its surface. Compared to existing technologies, this invention allows the positioning pin to be inserted into the corresponding positioning slot based on the different positioning posts that match the O-ring rubber seal. This limits the movement of the sealing ring positioning mechanism when the moving seat moves left, preventing excessive or insufficient movement of the O-ring rubber seal through the sealing ring positioning mechanism. This ensures effective burr removal, higher processing efficiency, lower defect rate, and greater convenience in actual use. Attached Figure Description

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0027] Figure 1 This is a schematic diagram of the overall structure of an O-ring burr removal device according to one embodiment of the present disclosure.

[0028] Figure 2 This is a schematic diagram of the burr removal mechanism 1 of an O-ring burr removal device according to one embodiment of the present disclosure.

[0029] Figure 3 This is a schematic diagram of the positioning and moving mechanism 2 and the sealing ring positioning mechanism 3 of an O-ring burr removal device according to one embodiment of the present disclosure.

[0030] like Figures 1-3 As shown, the O-ring burr removal device disclosed herein may include components such as: burr removal mechanism 1, positioning and moving mechanism 2, and sealing ring positioning mechanism 3.

[0031] like Figure 2 As shown in this disclosure, the burr removal mechanism 1 includes a worktable 11. A fixed frame 12 is fixedly installed on the top left side of the worktable 11. A rotating shaft 13 is rotatably nested on the bottom right side of the fixed frame 12 via a bearing. A motor 14, which is connected to the rotating shaft 13, is fixedly installed on the top of the fixed frame 12. Multiple grinding wheels 15 of different specifications are sequentially sleeved on the outside of the rotating shaft 13 from top to bottom. The outside of the rotating shaft 13 is provided with external threads. Two locking nuts 16 are sleeved on the outside of the rotating shaft 13 via external threads. The two locking nuts 16 are locked by the top and bottom of the multiple grinding wheels 15, respectively.

[0032] Therefore, after the O-ring rubber seal reaches the burr removal station, the rotating shaft 13 drives multiple grinding wheels 15 to rotate continuously under the drive of the motor 14. The grinding wheels 15 that are adapted to the positioning post 33 grind the O-ring rubber seal fixed on the outside of the positioning post 33, thereby removing the burrs on its surface.

[0033] like Figure 3 As shown, in a preferred embodiment, the positioning and moving mechanism 2 includes two parallel T-shaped guide rails 21. Both T-shaped guide rails 21 are fixedly mounted on the top of the workbench 11. A movable seat 22 is slidably sleeved on the top of the two T-shaped guide rails 21. A handle 23 is fixedly mounted on the front of the movable seat 22. Multiple positioning slots 24 are evenly provided on the left side of the top of any T-shaped guide rail 21. Chip removal grooves 25 extending to the front and back of the T-shaped guide rail 21 are provided on the inner side of any positioning slot 24. A positioning pin 26 is inserted into the inner side of any positioning slot 24. A reinforcing magnet 27 is fixedly mounted at the bottom of the positioning pin 26. The reinforcing magnet 27 is magnetically attracted to the adjacent T-shaped guide rail 21.

[0034] Therefore, the positioning pin 26 can be inserted into the positioning slot 24 that matches the positioning post 33, and the handle 23 can be used to move the moving seat 22 to the left along the T-shaped guide rail 21 until the moving seat 22 contacts the positioning pin 26. The positioning pin 26 blocks the moving seat 22. During this process, the moving seat 22 drives the O-ring rubber seal to the burr removal station in sync through the sealing ring positioning mechanism 3. Compared with the prior art, the positioning pin 26 can be inserted into the corresponding positioning slot 24 according to the different selections of the positioning post 33 that matches the O-ring rubber seal. Then, when the moving seat 22 drives the sealing ring positioning mechanism 3 to move to the left, it can limit the movement of the O-ring rubber seal by the sealing ring positioning mechanism 3, so as to avoid the situation where the moving seat 22 drives the O-ring rubber seal to move excessively or not to the correct position. This ensures the burr removal effect, while having higher processing efficiency, reducing the defect rate, and being more convenient in actual use.

[0035] In addition, the chip removal groove 25 can conveniently clean the grinding chips when they enter the positioning slot 24. At the same time, when cleaning the grinding chips inside the positioning slot 24, the grinding chips on the top of the T-shaped guide rail 21 are also cleaned away. The reinforcement magnet 27 ensures that the positioning pin 26 can be firmly inserted into the positioning slot 24.

[0036] like Figure 3As shown in this disclosure, the sealing ring positioning mechanism 3 includes a rotating seat 31 that is nested on the top plate of the movable seat 22 via a bearing. Multiple protrusions 32 are uniformly fixed on the outer side of the rotating seat 31. Multiple positioning posts 33 are coaxially arranged in the vertical direction and fixed on the top plate of the rotating seat 31 from bottom to top. Any positioning post 33 is adapted to the grinding wheel 15 that is collinear in the horizontal direction.

[0037] Therefore, the O-ring to be processed can be fitted onto the outside of the matching positioning post 33. At this time, the positioning post 33 fixes the O-ring through friction. In the subsequent grinding process, the rotating seat 31 is driven to rotate by multiple protrusions 32, which in turn drives the O-ring to rotate synchronously, so as to achieve full grinding of the surface of the O-ring.

[0038] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0039] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
