[0005] 2. The contact between the bearing ring and the rotating plate makes it easy for the outer circumference grinding block of the bearing ring to be blocked by the rotating plate, making it inconvenient to set a load-bearing structure on the support block to create a gap between the bearing ring and the rotating plate. Utility Model Content
[0006] To address the aforementioned technical problems, this utility model provides a thrust bearing ring grinding device. This device solves the problems of high friction between the rotating and stationary plates, which easily leads to wear and damage to both plates; inconvenience in installing a spacer structure on the rotating plate to create a gap between them; and the bearing ring contacting the rotating plate, causing the outer circumferential grinding block of the bearing ring to be easily blocked by the rotating plate, making it inconvenient to install a load-bearing structure on the support block to create a gap between the bearing ring and the rotating plate.

A through-hole regular hexagonal hole is opened in the center of the rotating circular plate 2 to facilitate the insertion and synchronous rotation of the rotating bearing rod 3. Three T-shaped grooves in the inner and outer directions are arranged in an annular array on the outer periphery of the top end face of the rotating circular plate 2 to facilitate the movement of the clamping block 8 inside and outside. The rotating bearing rod 3 in the upper and lower directions is inserted into the regular hexagonal hole of the rotating circular plate 2 to facilitate the synchronous rotation of the rotating circular plate 2 by the rotating bearing rod 3. A threaded rod is provided at the top of the rotating bearing rod 3 to facilitate the clamping and adjusting cylinder 5 to be installed by the thread.

A regular hexagonal hole is provided on the bottom end face of the threaded rod of the rotating bearing rod 3. The rotating support rod 3 has a hexagonal prism at its bottom end face, which facilitates the synchronous rotation of the rotating circular plate 2. A fixed post is provided on the bottom end face of the fixed post of the rotating support rod 3, allowing the stationary support plate 4 to be installed via bearings. A regular hexagonal groove is provided on the bottom end face of the fixed post of the rotating support rod 3, allowing the external power device shaft to be inserted to drive the rotating support rod 3 to rotate. The stationary support plate 4 is installed on the fixed post of the rotating support rod 3 via bearings, facilitating the support of various components. A through-hole bearing hole is provided in the center of the stationary support plate 4, facilitating the installation of the rotating support rod 3 via bearings. A vertically oriented clamping adjustment cylinder 5 is installed on the threaded rod of the rotating support rod 3 via threads, facilitating the lifting and lowering of the clamping adjustment cylinder 5 through threaded engagement. Threads are provided on the inner circumference of the clamping adjustment cylinder 5, facilitating threaded installation. A bearing ring groove is provided on the inner circumference of the bottom of the clamping adjustment cylinder 5, facilitating the lifting and lowering of the support cylinder 6 via bearing installation. A regular hexagonal structure is provided on the outer circumference of the top of the clamping adjustment cylinder 5, facilitating rotational adjustment via tools.
[0028] The clamping adjustment cylinder 5 has a bearing ring groove inside which a vertically lifting bearing cylinder 6 is installed via a bearing. This allows the clamping adjustment cylinder 5 to move up and down via the bearing. The top outer circumference of the lifting bearing cylinder 6 has a bearing ring groove for easy installation of the clamping adjustment cylinder 5 via the bearing. The bottom end face of the lifting bearing cylinder 6 has three through-hole limiting grooves arranged in a ring array to facilitate the insertion of the upper end of the clamping linkage rod 7. Fixing holes are provided on both sides of the limiting grooves of the lifting bearing cylinder 6 to facilitate the rotation of the clamping linkage rod 7 via a fixed shaft. The vertically lifting clamping linkage rod 7 is installed inside the limiting groove of the lifting bearing cylinder 6 via a fixed shaft, facilitating the inward and outward movement of the clamping block 8. Both ends of the clamping linkage rod 7 have semi-circular heads with flipping holes for easy rotation via a fixed shaft. The lower semi-circular head of the moving rod 7 is equipped with an inward and outward spreading clamping block 8 via a fixed shaft, which facilitates the spreading and fixing of the bearing ring. The bottom of the spreading and clamping block 8 is provided with a bearing plate, which facilitates the limiting and guiding of the bearing plate inside the T-shaped groove of the rotating circular plate 2. The top end face of the inner end of the bearing plate of the spreading and clamping block 8 is provided with a pair of vertical plates with mounting holes, which facilitates the clamping of the lower end of the connecting rod 7 via the fixed shaft. The top end face of the outer end of the bearing plate of the spreading and clamping block 8 is provided with a vertical spreading column, which facilitates the outward spreading and fixing of the bearing ring. The outer circumference of the spreading column of the spreading and clamping block 8 is provided with a square column in the inward and outward direction, which facilitates the bearing ring bearing. The bearing plate of the spreading and clamping block 8 is located inside the T-shaped groove of the rotating circular plate 2, which facilitates the inward and outward movement and guidance of the spreading and clamping block 8.
[0029] The specific usage and function of this embodiment are as follows:
[0030] In this utility model, such as Figure 1 As shown, the stationary bearing plate 4 is in a cut-off state. A thrust bearing ring is placed on top between the square columns of the clamping block 8, and the thrust bearing ring is in a tightened and fixed state. The front of the outer circumference of the thrust bearing ring is the cut-off part of the grinding structure. The grinding block behind the grinding structure contacts the outer circumference of the thrust bearing ring. When grinding the thrust bearing ring, the external power device shaft is inserted into the regular hexagonal groove of the rotating bearing rod 3, causing the rotating bearing rod 3 to rotate. The rotating bearing rod 3 drives the rotating circular plate 2 to rotate synchronously, thereby causing the thrust bearing ring to rotate and contact the grinding block, as shown in the figure. Figure 2As shown, this allows for the grinding of the outer circumference of the thrust bearing ring. Note that the grinding structure can be adjusted forward and backward, facilitating the adjustment of the grinding amount. When the clamping block 8 is moved inward and outward, the clamping adjusting cylinder 5 is engaged with the rotating bearing rod 3 by rotating the tool, causing the clamping adjusting cylinder 5 to rise and fall through the thread engagement. This, in turn, causes the lifting bearing cylinder 6 to rise and fall synchronously via the bearing. The lifting bearing cylinder 6 then drives the upper end of the clamping linkage rod 7 to rise and fall synchronously. Finally, the lower end of the clamping linkage rod 7 drives the clamping block 8 to move inward and outward. This method is suitable for clamping and fixing thrust bearing rings with different bore diameters.
[0031] Example 2: Unlike Example 1, the hexagonal structure of the clamping adjustment cylinder 5 can also be set as a regular heptagonal structure. This makes it necessary to use a special tool that works with the regular heptagonal structure to rotate the clamping adjustment cylinder 5, thus preventing non-staff members from rotating and adjusting the clamping adjustment cylinder 5.
[0032] Example 3: The difference from Example 1 is that the top end face of the square column of the supporting clamping block 8 can also be set as a frosted surface, thereby increasing the friction between the top end face of the square column of the supporting clamping block 8 and the bearing ring, and preventing the bearing ring from being displaced on the supporting clamping block 8.
