Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of shunt block manufacturing and relates to a shunt block fixture. Background Art
[0002] The shunt block is a core component in the production line of liquid crystal substrate glass and cover glass. The quality of its own processing has a great impact on the yield rate of liquid crystal glass and cover glass production lines. How to improve the processing quality of the shunt block is very important. In the traditional CNC programming processing of the shunt block, there is no unified standard fixture. Only a few refractory bricks are used to support and raise the shunt block blank. A set of pressure plate assemblies are used to press the top of the large end of the shunt block, and a set of super vises and a refractory brick body are used to tighten the small end. When processing the refractory brick body, in order to prevent the diamond ball head tool from getting stuck, the tool cannot be fed into the product for processing. The tool is outside the product every time it enters and exits the tool. Therefore, after the processing of the inclined surface on one side is completed, the refractory brick that is tightened by the super vise at the small end is less than half, and the tightening strength is reduced, which makes it easy for the shunt block to move and be scrapped. When processing the shunt block, one clamp and one top are used, and the side of the processing side symmetric surface is positioned, and the bottom is supported by refractory bricks or white steel bars. This positioning method has certain disadvantages in processing diverter blocks. Due to the vibration of processing and the shape limitation of the product, the refractory brick positioned at the small end of the diverter block can be reliably positioned under the extrusion of the super vise. However, after the curved surface processing on one side is completed, the force of the super vise squeezing the refractory brick will be unbalanced, resulting in displacement of the diverter block. In addition, the bottom support is not a whole and is prone to warping, so the qualified rate of diverter blocks is not high. Utility Model Content
