Description

Technical Field

[0001] The utility model relates to the field of electrical machining, and more specifically to an inner wall cleaning mechanism of a working liquid tank with a filtering function. Background Art

[0002] Electrospark machining is a method of machining a workpiece by electro-erosion caused by pulse discharge between the tool electrode and the workpiece electrode in a certain medium. When machining with a machine tool, a special working fluid tank is required to store the medium.

[0003] China Patent Authorization Announcement No.: CN219254402U, provides a working fluid tank for an electric machining machine tool. This patent can actively lift the working fluid tank without affecting the internal oil problem during the lifting operation, thereby facilitating manual access to the workpiece inside and improving the convenience of the operation.

[0004] In the existing technology, when the workpiece is undergoing electrolytic machining, the metal on its surface often produces a certain amount of metal waste chips. If the workpiece is close to the inner wall of the working fluid tank during machining, these waste chips will adhere to the tank wall. The existing electroplating machine tools do not have the function of cleaning the inner wall of the working fluid tank. During the long-term operation of the machine tool, the working fluid will gradually be contaminated by these waste chips, which will eventually reduce the electrolytic effect of the working fluid and reduce the machining efficiency of the machine tool.

[0034] The total length of the telescopic rod 24 is the same as the inner height of the working liquid tank body 1 .

[0035] The other two sides of the inner wall of the working liquid tank body 1 are slidably connected with the second cleaning brush plates 26 , and the second cleaning brush plates 26 are fixedly connected to the first cleaning brush plates 25 .

[0036] The specific implementation process of this embodiment is as follows: two motors 21 and two bidirectional screw rods 22 are respectively arranged on both sides of the interior of the working liquid tank body 1, and the threads at both ends of the bidirectional screw rod 22 are in opposite directions. The two threaded sliders 23 on the same bidirectional screw rod 22 are symmetrically arranged and are respectively connected to the positive and negative threads on both sides. After the motor 21 is started, the two threaded sliders 23 can be moved closer to or away from each other, and by rotating the connected telescopic rod 24, a downward thrust is given to the first cleaning brush plate 25, so that the first cleaning brush plate 25 and the second cleaning brush plate 26 slide downward. A brush is installed on one side of the first cleaning brush plate 25 and the second cleaning brush plate 26 close to the inner wall of the working liquid tank body 1, so that during the descent of the two, the waste chips on the inner wall of the working liquid tank body 1 are scraped off.

[0037] Embodiment 2:

[0038] See also Figure 1 one Figure 5 A circulation mechanism 3 is provided on one side of the working liquid tank body 1 , and the circulation mechanism 3 includes a pump body 32 fixedly connected to one side of the working liquid tank body 1 .

[0039] The water inlet end of the pump body 32 is fixedly connected with a water inlet pipe 31 , the water inlet pipe 31 is communicated with the working liquid tank body 1 , and the water outlet end of the pump body 32 is fixedly connected with a water outlet pipe 33 .

When the pump body 32 absorbs water, the scraped waste will enter the pump body 32 along with the water body, and then the pump body 32 transports the working fluid to the top of the filter plate 42 through the water outlet pipe 33. After the filter plate 42 filters the waste, the working fluid returns to the working fluid tank body 1 along the filter plate 42 to complete the filtration of the working fluid. Through the bolts 43, the staff can quickly disassemble and replace the filter plate 42.

[0044] The working principle of the utility model is: when it is necessary to clean the inner wall of the working liquid tank body 1, the staff first turns on the two motors 21 to rotate the two bidirectional screws 22, so that the telescopic rod 24 pushes the first cleaning brush plate 25 and the second cleaning brush plate 26 to move downward to scrape off the waste on the inner wall of the working liquid tank body 1, and then the staff controls the motor 21 to reverse, so that the telescopic rod 24 resets the first cleaning brush plate 25 and the second cleaning brush plate 26, and then repeats the above process many times until the staff determines that the waste on the inner wall of the working liquid tank body 1 is scraped off, the staff continues to turn on the pump body 32 to suck out the working liquid, and after the working liquid is sucked out, it passes through the filter plate 42 from the outlet pipe 33, and the filter plate 42 filters the waste in the working liquid, and the working liquid flows down from the filter holes of the filter plate 42 and returns to the inside of the working liquid tank body 1, thereby completing the filtering cycle of the working liquid.

[0045] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
