Description

Technical Field

[0001] The utility model relates to the technical field of electric spark machine tools, in particular to a filtering device for numerically controlled electric spark machine tools. Background Art

[0002] Electric spark machine, also known as CNC electric spark machine, electric spark, spark machine, etc., is an electrical processing equipment. When the switch contacts are damaged by spark discharge corrosion, it is found that the instantaneous high temperature of the electric spark can cause the local metal to melt, oxidize and corrode. This is the electric spark machining method.

[0003] Most of the filters used in CNC EDM machines on the market have the following problems when in use:

[0004] 1. Traditional CNC EDM machine filter devices are used in a unified internal filtering mode. When the processing liquid enters the filter device, a large amount of processing liquid will be directly filtered. If a large amount of processing liquid flows in at one time during the filtering process, it is easy to slow down the filtering speed, thereby affecting the overall filtering efficiency. There are certain limitations in use;

[0005] 2. Most of the filter devices used in CNC EDM machines need to ensure their sealing performance during use, so it is cumbersome to disassemble, which makes disassembly difficult. It is difficult for the staff to complete the disassembly of the filter device in a short time, and it is time-consuming and laborious to inspect and maintain it. It is also troublesome to replace the internal filter structure, and it is not convenient to operate. Utility Model Content

At the same time, since a first filter chamber 10 and a second filter chamber 11 are provided inside the device body 1, and the two inlet pipes 8 correspond to the first filter chamber 10 and the second filter chamber 11 respectively, the processing liquid entering the filtering device will be divided into two, and then the effect of simultaneous filtration on the left and right sides can be achieved. A large amount of processing liquid can be divided into two batches and poured into the interior of the filtering device, thereby achieving the purpose of reducing the single filtration amount and increasing the total integrated filtration amount, and there will be no filtration congestion. Finally, the processing liquid that completes the filtration effect will be discharged from the outlet pipe 9. At the same time, during the application of the filtering device, as the use time increases, the internal filtering structure needs to be inspected or cleaned and replaced. The filter screen 15 can be easily removed by screwing the screw cap 4 on the side plate 2 to remove the filter screen 15.

The problem solved by the utility model is that the existing filter devices for CNC EDM machines are all internally uniformly filtered when in use. When the processing liquid enters After entering the interior of the filter device, a large amount of processing liquid will be directly filtered. If a large amount of processing liquid flows in at one time during the filtering process, it is easy to slow down the filtering speed, thereby affecting the overall filtering efficiency. There are certain limitations in use. At the same time, most CNC EDM machine filter devices need to ensure their sealing performance during application, so it is more cumbersome to disassemble, which leads to higher difficulty in disassembly. It is impossible for the staff to complete the disassembly of the filter device in a short time. It is time-consuming and laborious to overhaul and maintain. It is also troublesome to replace the internal filtering structure. In order to solve the problems of inconvenience, the utility model combines the above-mentioned components, provides a first filter chamber 10 and a second filter chamber 11 structure inside the device body 1, and installs two inlet pipes 8 on the top of the device body 1, and the two inlet pipes 8 correspond to the first filter chamber 10 and the second filter chamber 11 respectively, so that the processing liquid entering the filtering device will be divided into two, and then the effect of filtering on the left and right sides at the same time can be achieved, and a large amount of processing liquid can be divided into two batches and poured into the inside of the filtering device, thereby reducing the single filtering amount and increasing the total integrated filtering amount, and there will be no filtering congestion. At the same time, since the side panels 2 structure are provided on both sides of the device body 1 , combined with the sealing block 5 installed on the inner side of the side plate 2 and the gasket 13 provided on the outer side of the device body 1, if it is necessary to inspect the interior of the filter device or clean and replace the filter frame, you only need to remove the side plate 2, and then the internal filter frame can be removed for replacement or cleaning, which is very convenient to operate. Then, when reinstalling, fix the side plate 2 on both sides of the device body 1. At this time, the sealing block 5 will be embedded in the interior of the device body 1, and the gasket 13 will be clamped between the device body 1 and the side plate 2, so that the double sealing effect can be achieved, which will not affect the sealing of the connection while facilitating disassembly, and is very practical.
