Abstract
Description
Technical Field
[0001] This utility model relates to the field of generator sealing tile grinding technology, and in particular to a special tool for grinding generator sealing tiles. Background Technology
[0002] Generator sealing tiles play a crucial role in generators, effectively sealing the internal gas environment, preventing external air intrusion, and reducing wear and vibration, thus ensuring the generator's long-term stable operation and safety. Their unique structure, complex maintenance process, and high precision requirements mean that post-disassembly grinding requires external suppliers, which is costly, time-consuming, and prone to deformation and damage during transport. Therefore, we designed a specialized tool for grinding generator sealing tiles. Manual grinding achieves a smoother, more precise surface, meeting high-quality grinding requirements, improving sealing performance, preventing leakage of hydrogen, lubricating oil, or air, and ensuring stable generator operation. Utility Model Content
[0003] The purpose of this invention is to provide a special tool for grinding generator sealing tiles, which can manually grind the sealing tiles to achieve the required grinding quality.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] This utility model proposes a special tool for grinding generator sealing tiles, including a pair of discs made of carbon steel. The opposing surfaces of the pair of discs each have a coaxially arranged circular protrusion, and the sealing tile to be ground is fitted over the pair of circular protrusions.
[0006] Furthermore, the thickness of the circular protrusion is greater than or equal to half the thickness of the sealing tile.
[0007] Furthermore, a through hole extending to the bottom of the disk is formed on the circular protrusion.
[0008] Furthermore, the disc is provided with three lifting holes.
[0009] The beneficial effects of this utility model are as follows: By cooperating with the two discs, the sealing tile can be manually ground without assembling it into the generator to measure the specific gap. At the same time, some defects such as burrs on the surface of the sealing tile are eliminated, eliminating the need to send it to the manufacturer for grinding. When not in use, it can be used as a professional tool to store the sealing tile to prevent deformation caused by improper storage. It can also be used to measure the fit clearance between the sealing tile and the generator journal, and to grind it according to the required fit dimensions. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] See also Figures 1 to 4 This utility model provides an embodiment:
[0017] See also Figure 1 , Figure 2 and Figure 3 A special tool for grinding generator sealing tiles includes a pair of discs 1 made of carbon steel. The opposing surfaces of the pair of discs 1 each have coaxially arranged circular protrusions 2. The sealing tile 3 to be ground is fitted over the pair of circular protrusions 2.
[0018] See also Figure 2 and Figure 3 The thickness of the circular protrusion 2 is greater than or equal to half the thickness of the sealing tile 3.
[0019] See also Figure 1 and Figure 3 A through hole 4 is provided on the circular protrusion 2, extending to the bottom of the disk 1. The through hole 4 can reduce the overall weight of the disk 1.
[0020] See also Figure 1 The disc 1 is provided with three lifting holes 5. The crane can move the disc 1 through the lifting holes 5.
[0021] Working principle: The circular protrusion 2 of disc 1 is placed upwards on the working area. The sealing tile 3 is fitted over the circular protrusion 2. Then, another circular protrusion 2 of disc 1 is installed downwards. The size of the circular protrusion 2 of disc 1 corresponds to the size of the generator journal 6. The gap between the sealing tile 3 and the circular protrusion 2 is measured, which is actually the gap between the sealing tile 3 and the generator journal 6. Disc 1 is a special disc made of carbon steel for grinding. The roughness of the grinding surface of disc 1 ensures that the surface roughness of the sealing tile 3 meets the requirements. A small margin is left on the outer diameter of disc 1 to prevent the sealing tile 3 from being damaged by bumping the edge. According to the standard requirements, the sealing tile 3 is manually rotated for grinding to the required size. If it is necessary to measure the size during the grinding process, a feeler gauge can be used.
