Electrode for electric discharge machine

The electrode for the electric discharge machine comprises an assembly column and a discharge block, a through hole is formed in the assembly column, a clamping block is installed in the through hole, an insertion rod is installed on the side, close to the assembly column, of the discharge block, a clamping groove matched with the insertion rod is formed in the clamping block, and the insertion rod is clamped in the clamping groove. The assembling column is provided with a locking piece used for locking the discharging block. The utility model provides an electrode for an electric discharge machine, which is convenient to disassemble and assemble a discharge part of the electrode, prevents the phenomenon that the discharge part is completely discarded when loss occurs, and can reduce the waste of raw materials. 本实用新型提出了一种电火花机用电极，包括装配柱、放电块，所述装配柱内开设有贯穿的通孔且通孔内安装有卡块，所述放电块靠近装配柱的一侧安装有插杆，所述卡块内开设有与插杆相适配的卡槽且插杆卡接在卡槽内，所述装配柱上设有用于锁定放电块的锁定件。本实用新型提出了一种电火花机用电极，能够便于对电极的放电部分进行拆装，防止出现损耗时全部丢弃的现象，可以减少原料的浪费。
