Description

Technical Field

[0001] The utility model relates to the technical field of spark machines, and particularly relates to a copper electrode fixture for a spark machine. Background Art

[0002] In the spark machining industry, copper electrodes are widely used as a common electrode material in the manufacturing of various precision molds. To ensure the stability and machining accuracy of copper electrodes during spark machining, fixtures are usually required to fix the copper electrodes. However, there are some deficiencies in the existing fixtures during use.

[0003] Traditional copper electrode fixtures require cumbersome adjustment work every time a copper electrode is replaced, even for copper electrodes of the same size. Such adjustments generally include, but are not limited to:

[0004] Positioning adjustment: The copper electrode needs to be accurately positioned on the fixture to ensure its position is correct.

[0005] Plane calibration: Tools such as a ruler are used to calibrate the plane of the copper electrode to ensure that the machining surface is horizontal.

[0006] Fastening operation: Ensure that the copper electrode does not shift or loosen during machining.

[0007] The above steps are not only time-consuming and laborious, but also increase the labor intensity of the operator and reduce production efficiency. Especially in application scenarios where copper electrodes need to be frequently replaced, these adjustment steps become one of the main factors restricting machining efficiency. Therefore, developing a quick-positioning fixture that can reduce adjustment time and improve the use efficiency of the fixture is of great significance for enhancing the overall efficiency of spark machining.
