It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0028] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0029] The utility model designs an electric spark machine tool with a filtering mechanism, which comprises a working tank, a working table, an electrode, a spraying member and a filtering assembly. The working table is arranged in the working tank and supports a workpiece. The electrode is used for processing the workpiece. The working fluid sprayed by the spraying member washes away the iron filings generated by the workpiece processing. The working tank is provided with a liquid outlet. The filtering assembly comprises a first filtering box 1, a filter screen 2, a lifting assembly and an ejector pin 6. The liquid inlet end 8 of the first filtering box 1 is connected to the liquid outlet. The filter screen 2 is arranged in the first filtering box 1 and is used for filtering the working fluid mixed with iron filings flowing out of the liquid outlet. The lifting assembly is connected to the first filtering box 1. The lifting assembly is used for driving one end of the ejector pin 6 to pass through the filtering hole of the filter screen 2.

[0030] It should be noted that the mixture of working fluid and iron filings flows into the first filter box 1 through the liquid outlet. The filter screen 2 is arranged in the first filter box 1, which can effectively filter out the iron filings in the working fluid. The design of the lifting assembly and the ejector pin 6 can clean the iron filings on the filter screen 2 to avoid clogging of the filter screen 2 and maintain the filtering effect, thereby solving the problem that the filter screen 2 of the spark machine in the prior art is easily clogged and the filtering effect is poor.

[0031] Specifically, the lifting assembly includes a lifter 4 and a lifting plate 5. The lifting plate 5 divides the first filter box 1 into a filtering area and a receiving area. The lifter 4 is arranged in the receiving area and connected to the lifting plate 5. The ejector pin 6 is connected to the lifting plate 5. The lifter 4 drives one end of the ejector pin 6 to pass through the filter net 2.

[0032] The lifter 4 of the utility model is a telescopic motor, and the ejector pin 6 corresponds to the filter hole of the filter screen 2 one by one. When the lifter 4 is working, the ejector pin 6 will move with the lifting plate 5. When one end of the ejector pin 6 passes through the filter hole, the iron filings can be separated from the filter hole, ensuring the smooth flow of the filter hole and avoiding the problem of poor filtering effect caused by blockage. Of course, in actual applications, people can also use other devices as the lifter 4, and the utility model is not limited to this.

[0033] Specifically, the first filter box 1 is also provided with a liquid outlet 7. When the lifter 4 drives one end of the ejector pin 6 to pass through the filter hole, the liquid outlet 7 is arranged between the lifting plate 5 and the filter net 2. When one end of the ejector pin 6 passes through the filter hole, the filtered liquid of the mixture of working fluid and iron filings can flow out through the liquid outlet 7.

[0034] Specifically, the EDM machine tool with a filtering mechanism further includes a second filter box, the liquid inlet of the second filter box is connected to the liquid outlet 7 of the first filter box 1 , and the second filter box is provided with a filter barrel 10 , which is used to filter the working fluid after being filtered by the filter net 2 .

[0035] Specifically, the spraying element is connected to the second filter box.

[0036] The working fluid after preliminary filtration in the filter box will flow into the second filter box for secondary filtration, which can further improve the cleanliness of the working fluid and remove tiny particles or impurities remaining in the working fluid. The spray piece is connected to the second filter box, and the working fluid after secondary filtration can be recycled.

[0037] Specifically, the electric spark machine tool with a filtering mechanism further includes a connecting piece, the first filter box 1 is connected to a fixing block 3, the fixing block 3 is provided with a connecting hole, the connecting piece passes through the filtering hole of the filter screen 2 and is threadedly connected to the connecting hole, so that the filter screen 2 is locked on the first filter box 1. The filter screen 2 and the first filter box 1 of the utility model are detachably connected, and when the filter screen 2 is damaged, people can replace it in time, and the applicability is high.

[0038] Specifically, the electric spark machine tool with a filtering mechanism also includes a waste trough, the first filter box 1 is provided with a discharge port and a cover plate 9, the cover plate 9 is opened and closed to connect the first filter box 1 to open and close the discharge port, the filter screen 2 is tilted, the waste trough is close to the lowest end of the filter screen 2, and the iron filings intercepted by the filter screen 2 enter the waste trough through the discharge port. The filter screen 2 of the utility model is tilted, when it is necessary to clean the iron filings, open the cover plate 9, and the iron filings intercepted by the filter screen 2 will naturally slide into the waste trough under the action of gravity, which can ensure that the waste is effectively collected and discharged, and avoid excessive accumulation of iron filings on the filter screen 2, affecting the filtering effect or causing the filter screen 2 to be blocked. Of course, it should be noted that the waste trough is detachably connected to the first filter box 1. When the waste trough is full of iron filings, people can remove the waste trough and pour the iron filings in the waste trough into the collection bag.

[0039] Specifically, the cover plate 9 is provided with a handle, which greatly facilitates the opening and closing of the discharge port. The EDM machine with a filtering mechanism also includes a connecting rope and a brush. One end of the connecting rope is connected to the handle, and the other end of the connecting rope is connected to the brush. When the iron filings of the filter screen 2 cannot naturally slide into the waste trough, the brush can be used to drive the iron filings to slide into the waste trough.

[0040] Specifically, the EDM machine tool with a filtering mechanism further includes heat dissipation fins and a heat dissipation fan, both of which are arranged in the second filter box, and the heat dissipation fins and the heat dissipation fan are used to cool the filtered working fluid.

[0041] The working fluid of the utility model will take away part of the heat generated by the workpiece processing when washing away the iron filings generated by the workpiece processing. After the working fluid mixed with the iron filings is filtered twice, the heat dissipation fins and the heat dissipation fan effectively reduce the temperature of the working fluid after the secondary filtration, ensuring that the working fluid maintains a suitable temperature during the circulation process.

[0042] Specifically, the EDM machine with a filtering mechanism also includes a smoke removal component and a circulation pump. The smoke removal component is used to absorb the exhaust gas generated by the electrode processing the workpiece. The circulation pump is connected to the second filter box and the spray component to transport the working fluid filtered by the filter barrel 10 to the spray component.

[0043] The smoke removal component of the utility model is used to absorb the waste gas generated during the electrode-workpiece processing process, which is crucial to maintaining the cleanliness of the working environment and the health of the operator. The circulating pump transports the working fluid filtered by the filter barrel 10 to the spray component, realizing the recycling of the working fluid and saving resources.

[0044] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
