Description

Technical Field

[0001] The present application relates to the field of wire cutting machine tools, and in particular to a wire cutting machine tool with stable positioning. Background Art

[0002] Wire cutting machines belong to the category of electrical machining. Their basic physical principle is that free positive ions and electrons accumulate in the field and quickly form an ionized conductive channel. The instantaneous high temperature of the electric spark can cause local metal to melt, oxidize and corrode, thereby completing the cutting process of the metal.

[0003] Since the wire cutting machine has high processing accuracy and can process parts with more complex shapes, it is necessary to use the wire cutting machine to process the complex structure of the needle parts of the sock machine. However, when positioning the workpiece, the traditional wire cutting machine usually uses a pressure plate and bolts. The pressure plate is pressed on the workpiece, and then the bolts are tightened to fix the workpiece. During the fixation of the workpiece, the workpiece needs to be neatly stacked first, and then pressed by the pressure plate. In addition, the other side of the pressure plate needs to be supported by a support of the same height, so that the bolts are not easily damaged due to the force of the single plate. The overall fixing process is relatively cumbersome. Utility Model Content

[0013] By adopting the above technical solution, the fixed screw can move with the slider, so that when fixing a workpiece that is inconvenient to place in the middle of the cutting table, the position of the fixed screw machine mounting plate can be adaptively adjusted, which has wider applicability.

[0014] Optionally, a fixing tube is coaxially arranged on the top wall of the mounting plate, the fixing tube and the fixing screw are rotationally matched, a plurality of reinforcing ribs are arranged between the side wall of the fixing tube and the top wall of the mounting plate, and the reinforcing ribs are evenly spaced around the rotation axis of the mounting plate.
