[0021] The automatic electrode replacement device of the electric spark machining machine in the utility model, when used normally, the electrode is fixed on the clamping block 6, when the electrode of the device needs to be replaced, the cylinder 2 is started to push out the tool magazine main body 3, and the device can realize the action of returning the old electrode and grabbing the new electrode through the cooperation of the actions of moving up and down and the spindle tensioning. When the electrode of different sizes needs to be used, the clamping block 6 for fixing the electrode needs to be replaced, the top cover 10 is opened, the hooking block 5 of the clamping block 6 is taken out from the hooking groove 4, the hooking block 5 of the new clamping block 6 is put into the hooking groove 4, and finally the top cover 10 is closed, so that the replacement process is simple, convenient and fast. The cylinders 2 involved in the utility model are controlled by the control system of the electric spark machine. Since the electric spark machine is a mature existing device, no more description is made here. In addition, the structure of the tool magazine mounting bracket 1 and the cylinder 2 in the utility model is similar to the electrode replacement device structure of the electric spark forming machine disclosed in the patent with the patent authorization announcement number CN221110202U, so no more description is made here.

[0022] As shown in Figure 1 and Figure 2 , the bottom of the clamping block 6 is fixedly connected with a supporting plate 7. The electrode is supported by the supporting plate 7, so that the friction between the electrode and the clamping block 6 is sufficient to fix the electrode, so that the electrode does not slide down, and the device can grab the electrode.

[0023] As shown in Figure 1 , Figure 2 and Figure 3As shown, the two ends of the top cover 10 are fixedly connected with connecting plates 11, and one side of the connecting plate 11 is fixedly connected with elastic lugs 12. The two ends of the tool magazine body 3 are fixedly connected with clamping plates 13 matched with the elastic lugs 12.

[0024] As shown in Figure 2 and Figure 3 , the two ends of the bottom of the top cover 10 are fixedly connected with sliding blocks 9, and the two ends of the top of the tool magazine body 3 are provided with sliding grooves 8 matched with the sliding blocks 9.

[0025] Specifically, when opening the top cover 10, only need to push the top cover 10, so that the elastic lugs 12 are separated from the clamping plates 13, and the top cover 10 can be opened. When closing the top cover 10, only need to push the top cover 10 to the direction of the clamping block 6, so that the elastic lugs 12 are inserted into the clamping plates 13, and the top cover 10 can limit the hooking block 5, avoiding the clamping block 6 from separating from the tool magazine body 3.

[0026] As shown in Figure 1 and Figure 3 , the side of the top cover 10 close to the tool magazine mounting bracket 1 is fixedly connected with a positioning frame 14, and the positioning frame 14 is sleeved outside the tool magazine mounting bracket 1.
