[0004] However, the above-mentioned fixing device for grinding the mechanical seal ring still has the following shortcomings:

[0005] The above device requires frequent tightening of several bolts to realize the disassembly and assembly of the mechanical seal ring, which is time-consuming and labor-intensive and reduces the processing efficiency of the seal ring. In view of this, we propose a sealing surface grinding tool for a silicon carbide mechanical seal ring. Utility Model Content

[0023] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0024] A silicon carbide mechanical seal ring sealing surface grinding tool, see Figures 1 to 3 , including a base 1, two groups of support rods 2 are evenly distributed in a ring on the upper surface of the base 1, the top of the support rod 2 is connected to a hollow frame 3, three limit frames 4 are evenly distributed in a ring outside the hollow frame 3, an adjustment mechanism 5 is provided on the side of the hollow frame 3, three supporting components 6 are evenly distributed in a ring on the top of the adjustment mechanism 5, and a silicon carbide sealing ring body 7 is provided between the three supporting components 6.

[0025] It is worth noting that the adjustment mechanism 5 includes a motor 501, which is engaged with the inner side of the middle part of the surface of the base 1, and the movable end of the motor 501 is connected to the active bevel gear 502, and three driven bevel gears 503 are evenly distributed on the surface of the active bevel gear 502 in an annular shape, wherein the active bevel gear 502 matches and meshes with the driven bevel gear 503, and the active bevel gear 502 forms a meshing transmission structure with the driven bevel gear 503 through the motor 501, and a screw 504 is fixed to the middle of the driven bevel gear 503, and a threaded block 505 is sleeved on the surface of the screw 504. Furthermore, the hollow frame 3 and the limit frame 4 are integrally formed, and the screw 504 runs through the inside of the limit frame 4. The side surface of the threaded block 505 always fits the inner wall of the limit frame 4, and the top of the threaded block 505 is fixed with a bent rod 506. Furthermore, the bent rod 506 fits horizontally to the bottom and the top of the hollow frame 3. The present invention effectively drives the active bevel gear 502 to rotate forward and reverse through the motor 501, thereby driving the driven bevel gear 503 engaged with the surface of the active bevel gear 502 to rotate forward and reverse, and then driving the screw 504 to rotate forward and reverse. Since the threaded block 505 is sleeved on the surface of the screw 504 and the limit frame 4 limits the threaded block 505, the forward and reverse rotation of the screw 504 can drive the threaded block 505 and the bending rod 506 to translate back and forth, which is convenient for quickly adjusting the distance between the supporting components 6, thereby realizing rapid disassembly and assembly of the silicon carbide sealing ring body 7.

[0026] It is worth noting that the supporting assembly 6 includes a support plate 601, which is fixed to the top surface of the bending rod 506. A slide groove 602 is opened inside the support plate 601, and a supporting plate 603 is clamped inside the slide groove 602. A group of extension plates 604 are symmetrically provided on one side of the support plate 601, wherein the support plate 601 and a group of extension plates 604 are integrally formed, and the supporting plate 603 forms a sliding structure with the support plate 601 through the slide groove 602. The supporting plate 603 is I-shaped, and a number of card slots 605 are evenly opened inside the extension plate 604. An insertion rod 606 is clamped inside the support plate 603 and a group of card slots 605. The utility model changes the distance between the supporting plate 603 and the top of the support plate 601 by sliding the supporting plate 603 up and down, thereby adapting to the placement of silicon carbide sealing ring bodies 7 of different thicknesses, ensuring that the sealing surface of the silicon carbide sealing ring body 7 that needs to be ground is higher than the top of the support plate 601, thereby improving the grinding effect. When adjusting the height of the supporting plate 603, the insertion rod 606 is pulled out, and the supporting plate 603 can now slide freely along the slide groove 602. After sliding to the appropriate position, the insertion rod 606 is passed through the supporting plate 603 and the corresponding slot 605 to complete the limiting of the supporting plate 603.

[0027] Working principle: According to the thickness of the silicon carbide sealing ring body 7 that needs to be ground, the distance between the supporting plate 603 and the top of the support plate 601 is adjusted. When adjusting the height of the supporting plate 603, the insertion rod 606 is pulled out. At this time, the supporting plate 603 can slide freely along the slide groove 602. After sliding to the appropriate position, the insertion rod 606 is passed through the supporting plate 603 and the corresponding slot 605 to complete the position limiting of the supporting plate 603. Then, the motor 501 drives the active bevel gear 502 to rotate forward and reverse, thereby driving the driven bevel gear 503 that is meshed with the surface of the active bevel gear 502 to rotate forward and reverse. This in turn drives the screw 504 to rotate forward and backward. Since the threaded block 505 is sleeved on the surface of the screw 504 and the limit frame 4 limits the threaded block 505, the forward and reverse rotation of the screw 504 can drive the threaded block 505 and the bending rod 506 to translate back and forth, and quickly adjust the spacing between the supporting components 6, so as to realize the rapid clamping, limiting and subsequent disassembly of the silicon carbide sealing ring body 7 to be ground. When the silicon carbide sealing ring body 7 to be ground is limited, the sealing surface of the silicon carbide sealing ring body 7 is higher than the top of the support plate 601, and can be directly ground by the grinding device, which is more convenient.

[0028] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
