When the existing electric discharge machining machine is working, some electric discharge oil is easily attached to the surface of the electrode. When the electric discharge machining machine performs discharge work, high temperature will be generated. Part of the generated high temperature is absorbed by the electric discharge oil, and the other part is transferred to the electrode in the form of heat transfer. The electric discharge oil on the electrode is easily affected by the temperature of the electrode and adheres to the surface of the electrode, thereby affecting the accuracy of the electric discharge machining machine when discharging and processing the workpiece;

[0037] The lifting module 1 includes a driving cylinder 11. The housing of the driving cylinder 11 is fixedly connected to the upper side of the L-shaped support plate 6. The telescopic rod of the driving cylinder 11 passes through the L-shaped support plate 6. The telescopic rod of the driving cylinder 11 is fixedly connected to a connecting plate 15. The lower side of the connecting plate 15 is fixedly connected to an electrode 14. The two ends of the upper side of the connecting plate 15 are respectively fixedly connected to symmetric circular guide rods 12.

[0040] The two square rods 51 are respectively fixedly connected with the corresponding extrusion shafts 4.

[0041] Working principle: First, connect the connecting pipe 73 to an external air pump. Then, add an appropriate amount of electric discharge machining oil into the box body 5. Lower the electrode 14 into the box body 5 through the lifting module 1 to perform electric discharge machining on the electrode 14. When the machining of the electrode 14 is completed and degreasing is required, start the driving cylinder 11. The retraction of the telescopic rod of the driving cylinder 11 drives the connecting plate 15 to move upward. The connecting plate 15 drives the electrode 14 to move upward. At the same time, the connecting plate 15 respectively drives the corresponding circular guide rods 12 to move upward along the linear bearings 13, so that the electrode 14 is removed from the box body 5. At this time, turn off the driving cylinder 11. Then, start the first motor 32. The first motor 32 drives the bidirectional lead screw 37 to rotate. The bidirectional lead screw 37 respectively drives the corresponding sliders 33 to slide. The two sliders 33 respectively drive the semi-cylindrical tubes 36 to move towards each other through the L-shaped rods 34, so that the two semi-cylindrical tubes 36 respectively drive the arc-shaped oil-absorbing sponges 35 to move towards each other, so that the two arc-shaped oil-absorbing sponges 35 clamp the electrode 14. At this time, turn off the first motor 32;

[0042] Then, start the external air pump, so that the external gas enters the connecting pipe 73 and the semi-cylindrical pipe 71 through the air pump and is sprayed out through a group of nozzles 72. Since the group of nozzles 72 are distributed obliquely downward, the gas blows the electric discharge machining oil on the electrode 14 to flow downward. At the same time, start the second motor 21. The second motor 21 drives the lead screw 22 to rotate. The lead screw 22 drives the T-shaped slider 24 to move downward. The T-shaped slider 24 respectively drives the ball sliders 25 to move downward along the linear guide rails 23. At the same time, the T-shaped slider 24 drives the degreasing module 3 to move downward, so that the two arc-shaped oil-absorbing sponges 35 wipe the remaining electric discharge machining oil on the electrode 14, and the electric discharge machining oil on the electrode 14 is wiped off;

[0043] When there is too much oil on the arc-shaped oil-absorbing sponge 35, control the first motor 32 to rotate in the reverse direction, so that the two semi-cylindrical tubes 36 drive the arc-shaped oil-absorbing sponge 35 to leave the electrode 14, and control the adjustment module 2 to move downward, so that the two arc-shaped oil-absorbing sponges 35 move to both sides of the two extrusion shafts 4. Control the first motor 32 to rotate, so that the two semi-cylindrical tubes 36 respectively drive the corresponding arc-shaped oil-absorbing sponges 35 to move towards each other, so that the two extrusion shafts 4 squeeze the arc-shaped oil-absorbing sponge 35, and the excess electric discharge machining oil on the arc-shaped oil-absorbing sponge 35 is squeezed out.

[0044] Beneficial effects: When degreasing is required after the processing of the electrode 14 is completed, the electrode 14 is moved out of the box body 5 through the lifting module 1. Through the degreasing module 3, two arc-shaped oil-absorbing sponges 35 clamp the electrode 14. Through the blowing module 7, the external gas enters the connecting pipe 73 and the semi-circular pipe 71 through the air pump and is ejected through a group of nozzles 72. Since the group of nozzles 72 are distributed obliquely downward, the gas blows the electric discharge machining oil on the electrode 14 to flow downward. At the same time, through the adjustment module 2, the two arc-shaped oil-absorbing sponges 35 wipe the residual electric discharge machining oil on the electrode 14, so that the electric discharge machining oil on the electrode 14 is wiped off. When there is too much oil on the arc-shaped oil-absorbing sponge 35, the two extrusion shafts 4 extrude the arc-shaped oil-absorbing sponge 35, so that the excess electric discharge machining oil on the arc-shaped oil-absorbing sponge 35 is extruded out.
