Description

Technical Field

[0001] The utility model relates to an electric spark wire cutting machine tool, in particular to a separate positioning mechanism for a medium wire cutting machine tool. Background Art

[0002] A wire cutting machine is an electrical machining machine. Its basic working principle is to use a continuously moving thin metal wire as an electrode to perform pulsed spark discharge to erode metal and cut the workpiece into shape. During the cutting process, the workbench serves as a platform for placing the workpiece and can move along the X and Y axis directions to achieve precise positioning of the workpiece during the processing. However, in conventional wire cutting machines, the X-axis positioning mechanism and the Y-axis positioning mechanism are stacked vertically, which makes the vertical position of the workbench and the workpiece it carries relatively high, making it inconvenient to load and unload the workpiece, and the structure of the workbench is relatively complex, which makes it easy to have inaccurate positioning. Therefore, it is necessary to optimize the structure of this positioning mechanism to overcome the above-mentioned defects. Utility Model Content
