Description

Technical Field

[0001] This utility model relates to the field of rubber ring production, and more specifically, it relates to a positioning fixture for rubber ring processing. Background Technology

[0002] Rubber rings are very common in industrial production. They are used to seal the connection between two pipe fittings, act as a buffer structure, and increase friction. They have a wide range of applications in industrial production. After the rubber rings are manufactured, they often need to be ground around their edges to remove burrs and other imperfections, thus ensuring production quality. During grinding, the rubber rings need to be fixed and positioned. Since different surfaces of the rubber ring require different fixing methods, existing positioning fixtures often only fix flat rubber rings, thus achieving grinding of flat surfaces. When grinding curved surfaces, they cannot effectively position and fix the rubber ring. Furthermore, because different rubber rings have different thicknesses, the positioning fixtures cannot be adjusted according to the thickness of the rubber ring. Therefore, when the rubber ring is thick, the contact area between the positioning fixture and the rubber ring is too small, resulting in unstable fixing and affecting the processing quality.

Beneficial effects

[0012] Compared with the prior art, this utility model provides a positioning fixture for rubber ring processing, which has the following beneficial effects: This utility model, by setting a movable block and a first mounting plate and a second mounting plate, allows for the selection of different fixing structures when processing different surfaces of the rubber ring. The first and second mounting plates are installed on the movable block through mounting holes that engage with mounting posts on the movable block. A limiting plate is installed through a threaded connection between the limiting plate and the mounting post, thereby limiting the first or second mounting plate and completing the installation of the first or second fixing structure. This facilitates the selection and installation of the first or second fixing structure according to processing requirements.

[0013] This utility model, by setting a first fixing structure, allows for the installation of a rubber ring on its surface. Two sets of first mounting plates are mounted on a movable block, and the rubber ring is fitted onto the arc-shaped pieces of the two sets of first mounting plates. Based on the thickness of the rubber ring, an extension piece is pulled out from the mating groove on the arc-shaped piece, aligning the connecting hole on the arc-shaped piece with the connecting hole on the extension piece. A bolt is inserted into the connecting hole to fix the position of the extension piece. The combined length of the arc-shaped piece and the extension piece adapts to the thickness of the rubber ring. Rotating the first threaded rod, through its two oppositely oriented threads and the threaded connection with the movable block, causes the two first fixing structures to move closer or further apart. This, in turn, clamps the inner ring of the rubber ring with the combination of the two arc-shaped pieces and the extension piece, facilitating the fixing of the inner wall of the rubber ring and completing its fixation and positioning.

[0014] This invention, by setting a second fixing structure, allows for vertical fixing of the rubber ring and processing of its arc-shaped surface. A second mounting plate is installed on the moving block, and the rubber ring is fitted onto two fixing rods. Rotating the second threaded rod, through its threaded connection with the mating block, moves the two mating blocks and fixing rods closer or further apart. When the fixing rods move to the desired position, the second positioning hole on the positioning plate of the mating block engages with different second positioning holes on the rotating frame. Rotating the second positioning rod, through its connection with the second positioning hole on the rotating frame, fixes the positions of the fixing rods and mating blocks, thus securing the rubber ring to the rotating frame. The rotational connection between the support frame and the rotating frame facilitates the rotation of the rubber ring during processing, thereby facilitating the processing of its arc-shaped surface.

[0022] More specifically, the first fixing structure facilitates fixing the rubber ring when processing the flat surface of the rubber ring, and the second fixing structure facilitates fixing the rubber ring when processing the curved surface of the rubber ring.

[0023] Please see Figures 1-5 As one embodiment for fixing the rubber ring during surface processing: the arc-shaped piece 6 is provided with a mating groove 15, the extension piece 7 is disposed in the mating groove 15, and both the extension piece 7 and the arc-shaped piece 6 are provided with connecting holes 16. Multiple connecting holes 16 are provided, and threads are provided in the connecting holes 16. Specifically, when installing the rubber ring on the surface, two sets of first mounting plates 4 are installed on the moving block 28, and the rubber ring is fitted onto the arc-shaped pieces 6 of the two sets of first mounting plates 4. According to the thickness of the rubber ring, the extension piece 7 is pulled out from the mating groove 15 opened on the arc-shaped piece 6, so that the connecting hole 16 opened on the arc-shaped piece 6 is aligned with the connecting hole 16 of the extension piece 7.

Thus, the combined length of the arc-shaped piece 6 and the extension piece 7 adapts to the thickness of the rubber ring. The first threaded rod 11 is rotated, and through the two threads with opposite directions on the first threaded rod 11 and the threaded connection with the moving block 28, the two first fixed structures are driven to move closer or further apart, thereby clamping the inner ring of the rubber ring through the combination of the two arc-shaped pieces 6 and the extension piece 7.

[0024] Please refer to Figure 1-5As one embodiment for fixing the rubber ring during arc surface processing: a fixing block 17 is fixedly installed at one end of the second mounting plate 5; a rotating hole 18 is provided on the support frame 10; a rotating column 19 is fixedly installed on the rotating frame 8; a second mounting groove 20 is provided on the rotating frame 8; a mating block 21 is provided at the lower end of the fixing rod 9; the rotating column 19 and the rotating hole 18 are mutually engaged and rotatably connected; both the rotating frame 8 and the support frame 10 are provided with first positioning holes 22; a first positioning rod 23 is provided in the first positioning hole 22 of the rotating frame 8. The first positioning rod 23 is threadedly connected to the first positioning hole 22. A second threaded rod 24 is provided on the rotating frame 8 in the second mounting groove 20. The second threaded rod 24 is rotatably connected to the rotating frame 8. The mating block 21 and the second mounting groove 20 are mutually mated. The second threaded rod 24 passes through the mating block 21 and is threadedly connected to the mating block 21. Positioning pieces 25 are provided at both ends of the mating block 21. The positioning pieces 25 and the rotating frame 8 are both provided with second positioning holes 26. The second positioning holes 26 are threaded. A second positioning rod 27 is provided in the second positioning hole 26 on the positioning piece 25. The second positioning rod 27 is threadedly connected to the second positioning hole 26. Specifically, when it is necessary to vertically fix the rubber ring and process the arc surface of the rubber ring, a second mounting plate 5 is installed on the moving block 28, and the rubber ring is fitted onto the two fixed rods 9. The second threaded rod 24 is rotated, and through the threaded connection between the second threaded rod 24 and the mating block 21, the two mating blocks 21 and the fixed rods 9 are moved closer or further apart. When the fixed rods 9 move to the required position, the second positioning hole 26 on the positioning piece 25 of the mating block 21 is engaged with the different second positioning holes 26 on the rotating frame 8. The second positioning rod 27 is rotated, and through the connection between the second positioning rod 27 and the second positioning hole 26 on the rotating frame 8, the position of the fixed rods 9 and the mating block 21 is fixed, thereby fixing the rubber ring on the rotating frame 8. Thus, through the rotational connection between the support frame 10 and the rotating frame 8, it is convenient to rotate the rubber ring during the processing.

[0025] In summary, when using it as a whole: When processing different surfaces of the rubber ring, different fixing structures are selected. The first mounting plate 4 and the second mounting plate 5 are installed on the moving block 28 by cooperating with the mounting holes 12 on the first mounting plate 4 and the second mounting plate 5 and the mounting posts 13 on the moving block 28. The limiting plate 14 is installed by the threaded connection between the limiting plate 14 and the mounting post 13, thereby limiting the first mounting plate 4 or the second mounting plate 5 by the limiting plate 14, thus completing the installation of the first fixing structure or the second fixing structure.

[0026] When installing the rubber ring on the surface, two sets of first mounting plates 4 are installed on the moving block 28, and the rubber ring is fitted onto the arc-shaped pieces 6 of the two sets of first mounting plates 4. According to the thickness of the rubber ring, the extension piece 7 is pulled out from the mating groove 15 opened on the arc-shaped piece 6, so that the connecting hole 16 opened on the arc-shaped piece 6 is aligned with the connecting hole 16 of the extension piece 7. The bolt is inserted into the connecting hole 16 to fix the position of the extension piece 7. Thus, the combined length of the arc-shaped piece 6 and the extension piece 7 adapts to the thickness of the rubber ring. The first threaded rod 11 is rotated, and through the two threads with opposite directions on the first threaded rod 11 and the threaded connection with the moving block 28, the two first fixed structures are driven to move closer or further away from each other, thereby clamping the inner ring of the rubber ring through the combination of the two arc-shaped pieces 6 and the extension piece 7.

[0027] When it is necessary to vertically fix the rubber ring and process the arc surface of the rubber ring, a second mounting plate 5 is installed on the moving block 28, and the rubber ring is fitted onto the two fixed rods 9. The second threaded rod 24 is rotated, and through the threaded connection between the second threaded rod 24 and the mating block 21, the two mating blocks 21 and the fixed rods 9 are moved closer or further apart. When the fixed rods 9 move to the required position, the second positioning hole 26 on the positioning piece 25 of the mating block 21 is engaged with the different second positioning holes 26 on the rotating frame 8. The second positioning rod 27 is rotated, and through the connection between the second positioning rod 27 and the second positioning hole 26 on the rotating frame 8, the position of the fixed rods 9 and the mating block 21 is fixed, thereby fixing the rubber ring on the rotating frame 8. Thus, through the rotational connection between the support frame 10 and the rotating frame 8, it is convenient to rotate the rubber ring during the processing.

For all the fixed connections mentioned above, welding is preferred.
