Description

Technical Field

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

[0002] Rubber seals are a commonly used accessory in industrial production. They are ring-shaped covers consisting of one or more parts, fixed to one of the bearing rings or washers and in contact with another ring or washer or forming a narrow labyrinth gap to prevent lubricating oil leakage and foreign matter intrusion.

[0003] After the rubber sealing ring is processed, there is often residual rubber from the previous process adhering to the inside of the rubber sealing ring. This can affect the sealing performance of the rubber sealing ring during subsequent use and hinder the subsequent installation of the rubber sealing ring.

[0004] There is a type of rigid rubber sealing ring that requires small-batch manual grinding to remove residual rubber inside the sealing ring. Therefore, a device is needed to fix the rubber sealing ring so that workers can then correct and remove the residual rubber inside. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems by providing a grinding device for O-ring rubber seals.

[0006] To address the aforementioned problems, a grinding device for O-ring rubber seals is provided, characterized in that it includes a mounting base, a support block, a pressing block, a pressing bolt, and a locking bolt. The mounting base is an integral coaxial hollow cylinder. At least three sets of guide grooves are provided on the side wall of the mounting base near the bottom surface. At least two sets of clamping plates are integrally cast on both sides of the guide grooves. A support block is provided between the first clamping plate and the second clamping plate. A locking bolt is provided on one side of the support block. The locking bolt passes through the first clamping plate, the support block, and the second clamping plate respectively.

[0007] Preferably, each of the multiple sets of support blocks has a transverse strip groove on its sidewall that extends through the support block, and the longitudinal height of the strip groove is greater than the diameter of the locking bolt.

[0008] Preferably, at least three sets of extrusion bolts are evenly distributed on the side wall of the mounting base near the top, with the center of the mounting base as the axis, and they penetrate the side wall of the mounting base. Each extrusion bolt has an extrusion block glued to its threaded end, and the end face of the extrusion block near the center of the mounting base is an arc-shaped surface.

[0009] Preferably, the bottom of the mounting base is provided with at least two sets of fixing blocks, the fixing blocks are U-shaped and bolts are provided in the U-shaped curved cavity for connecting the grinding device to the worktable.

[0010] Preferably, the thickness of the clamping plate is ≤5mm.

[0011] Preferably, there is a gap between the first clamping plate and the second clamping plate and the support block.

[0012] In summary, the beneficial effects of this utility model are:

[0013] This invention modifies part of the structure to allow the bottom support block to be adjusted horizontally. It can be adjusted to a suitable position without exceeding the inner ring of the rubber sealing ring or the center hole. Then, the rubber ring is placed on the multiple sets of support blocks, and finally, the compression bolts are tightened to compress the rubber sealing ring to the outside of the rubber sealing ring, thus completing the fixation of the rubber sealing ring.

[0020] Please see Figure 1 As shown, a grinding device for O-ring rubber seals includes a mounting base 1, a support block 131, an extrusion block 162, an extrusion bolt 161, and a locking bolt 141. The mounting base 1 is a coaxial hollow cylinder. At least three sets of guide grooves are provided on the side wall of the mounting base 1 near the bottom. At least two sets of clamping plates are integrally cast on both sides of the guide grooves. A support block 131 is provided between the first clamping plate 111 and the second clamping plate 121. A locking bolt 141 is provided on one side of the support block 131. The locking bolt 141 passes through the first clamping plate 111, the support block 131, and the second clamping plate 121 respectively.

[0021] Please see Figure 2 As shown, the sidewalls of multiple sets of support blocks 131 are provided with transverse strip grooves 132 that penetrate through the support blocks 131, and the longitudinal height of the strip grooves 132 is greater than the diameter of the locking bolts 141.

[0022] Furthermore, on the side wall of the mounting base 1 near the top, with the center of the mounting base 1 as the axis, at least three sets of extrusion bolts 161 are evenly distributed and penetrate through the side wall of the mounting base 1. The threaded end of each extrusion bolt 161 is glued with an extrusion block 162, and the end face of the extrusion block 162 near the center of the mounting base 1 is an arc-shaped surface.

[0023] Furthermore, the bottom of the mounting base 1 is provided with at least two sets of fixing blocks 151. The fixing blocks 151 are U-shaped and bolts are provided in the U-shaped curved cavity for connecting the grinding device to the worktable.

[0024] Furthermore, the thickness of the first clamping plate 111 and the second clamping plate 121 is ≤5mm.

[0025] Furthermore, there is a gap between the first clamping plate 111 and the second clamping plate 121 and the support block 131.

[0026] When using this utility model, the locking bolt 141 needs to be loosened to release the clamping of the first clamping plate 111 and the second clamping plate 121 from the support block 131, so that the bottom support block 131 can be adjusted to a horizontal position. Adjust it to a suitable position according to the inner diameter of the rubber sealing ring, so that the support block 131 can effectively support the rubber sealing ring. Then, place the rubber ring on multiple sets of support blocks 131, and finally tighten the extrusion bolt 161 so that the extrusion block 162 extrudes the outside of the rubber sealing ring to complete the fixing of the rubber sealing ring.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not restrictive. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
