Description

Technical Field

[0001] The utility model relates to the technical field of mirror plate grinding devices, in particular to a mirror plate grinding cloth clamping device. Background Art

[0002] During the power generation process of the hydro-turbine generator set, the induced current generated on the mirror plate surface and the tiny impurities in the lubricating oil will cause certain damage to the mirror plate surface, causing its surface roughness to decrease. When the surface roughness decreases to a certain extent, it will cause thrust bearing wear, bearing temperature increase or bearing burning and other operating failures. At the same time, with the widespread application of elastic plastic thrust bearings, it has more stringent requirements on the surface finish of the mirror plate. According to the standard, the mirror plate finish should reach level nine (Ra=0.2) or above, and scars, high spots, cracks and burns are not allowed on the mirror surface.

[0003] When a grinding device is used to grind a mirror plate, a grinding cloth needs to be installed on the grinding device. However, most existing grinding cloth installation devices are not convenient for clamping and installing grinding cloths of different lengths.

[0004] At present, there are many types of grinding cloth clamping devices for mirror plate grinding on the market. Most of these devices use mechanical clamping or magnetic suction to fix the grinding cloth. These traditional methods can meet basic grinding needs to a certain extent, but there are generally some problems and shortcomings. Specifically, during long-term use, the traditional grinding cloth clamping device is prone to loosening or falling off due to changes in clamping force or wear, thereby affecting the grinding quality and efficiency. In addition, some devices are cumbersome to operate when replacing the grinding cloth, which reduces production efficiency and is not conducive to the integration of automated production lines.

[0005] Specific problems and defects are:

[0006] 1. Insufficient clamping stability: During long-term or high-intensity grinding, the existing grinding cloth clamping device often finds it difficult to maintain a stable clamping force due to wear or fatigue of the clamping mechanism, causing the grinding cloth to loosen or deviate, thereby affecting the grinding accuracy and surface quality;

[0007] 2. Inconvenient replacement of grinding cloth: When replacing the grinding cloth, traditional devices usually need to manually disassemble multiple parts, which is complicated and time-consuming, which not only reduces production efficiency but also increases the labor intensity of workers. At the same time, frequent disassembly and installation may also cause additional wear and tear on the equipment;

[0008] 3. Low degree of automation: With the development of intelligent manufacturing technology, the automation level of production lines is increasingly required. However, many existing grinding cloth clamping devices have limitations in automation integration, making it difficult to seamlessly connect with advanced automated production lines, limiting the improvement of production efficiency and intelligence level.

[0009] For example, CN202726720U discloses a grinding cloth clamp, comprising: a power transmission device, an elastic motion mechanism and a clamping mechanism; wherein one end of the power transmission device is connected to a power source, and the other end is connected to the elastic motion mechanism, and the elastic motion mechanism is also connected to the clamping mechanism; the grinding cloth clamp of the utility model is mainly used for cleaning the grinding cloth, and it cannot adjust the length and angle of the grinding cloth, and is also not suitable for grinding mirror plates.
