Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The neutralization tank 805 is installed on the side of the base 1, the negative pressure pump 804 is installed on the neutralization tank 805, and the discharge port extends into the neutralization tank 805.

[0024] By installing the exhaust gas purification mechanism 8, the suction cup cover 801 covers the spark machine head 6, and the negative pressure pump 804 works, so that the suction cup 802 generates suction to absorb the metal chip smoke generated when the workpiece is subjected to electric spark machining and the gas generated by the evaporation of the working fluid, and injects them into the neutralization tank 805 along the guide pipe 803. The metal chip smoke is precipitated in the neutralization tank 805, and the gas generated by the evaporation of the working fluid is cooled and absorbed, thereby reducing the pollution of the air caused by electric spark machining and improving the safety of electric spark machining.

[0025] refer to Figure 1-2 An oil pool cover sliding track 306 is provided on the top of the spark machine oil pool 3, and a retractable oil pool cover 307 is installed on the oil pool cover sliding track 306. The outer side of the retractable oil pool cover 307 is fixed to the top of the pool wall on both sides of the spark machine oil pool 3.

The retractable distance of the retractable oil pool cover 307 is adjusted so that it can always extend to the edges of both sides of the suction cup cover 801, thereby increasing the coverage area of ​​the retractable oil pool cover 307, reducing the diffusion of toxic and harmful gases and particles, and assisting the exhaust gas purification mechanism 8 to purify the exhaust gas.

[0027] How to use

[0028] The working principle and use process of the utility model are as follows: during electrospark machining, the workpiece is fixed on the workpiece fixing seat 4, and the tool setting operation is performed first. After the tool setting is completed, the retractable oil pool cover 307 is pulled to the spark machine head 6 to cover the spark machine oil pool 3 to reduce the diffusion of toxic and harmful gases and particles from the opening of the spark machine oil pool 3 during operation. The spark machine machining is started, and the oil inlet pump 303 works to draw the working fluid from the spark machine oil tank 304 and inject it into the spark machine oil pool 3 through the oil inlet 301 until the electrode 7 is completely submerged. The electrode 7 moves downward to approach the workpiece, and the working fluid is punctured to cause spark discharge to corrode the workpiece. The high temperature during the machining process causes the workpiece to produce The metal chip smoke and the gas generated by the evaporation of the working fluid are turned on the negative pressure pump 804 to make the suction cup 802 generate suction to absorb the metal chip smoke and toxic and harmful gases, and inject them into the neutralization tank 805 along the conducting pipe 803. The metal chip smoke is precipitated in the neutralization tank 805, and the toxic and harmful gases are cooled, neutralized and absorbed, thereby reducing the pollution of the air by the electrospark machining and improving the safety of the electrospark machining. After the machining is completed, the working fluid flows out from the oil outlet 302, and flows back to the spark machine oil tank 304 after being filtered by the filter mechanism 305. The filtration reduces the content of impurities in the working fluid, reduces the loss of the working fluid, and reduces the machining cost.
