DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following is combined with the attached Figures 1-3The present application will be further described in detail.
[0020] An embodiment of the present application discloses an oil supply device for a spark machine. Refer to Figure 1 and Figure 2 , an oil supply device for a spark machine, including a workbench 1, a storage oil tank 2 is fixedly connected to one side of the outer surface of the workbench 1, a circulation pump 5 is arranged on one side of the upper surface of the storage oil tank 2, and the model of the circulation pump 5 is preferably KWT-XCLYB type. All electrical components appearing in the present application are externally connected to a power supply and a control switch during use. A fuel injection pipe 6 is fixedly connected to one side of the upper surface of the circulation pump 5, and a nozzle 7 is fixedly connected to one side of the outer wall of the fuel injection pipe 6. The circulation pump 5 is connected to the fuel injection pipe 6, and the circulation pump 5 is communicated with the storage oil tank 2, so that the circulation pump 5 transports the cooling oil inside the storage oil tank 2 into the fuel injection pipe 6 and sprays it out from inside the nozzle 7, so as to cool the mechanism being processed. A plurality of second one-way valves 15 are arranged on one side of the lower surface of the storage oil tank 2. A plurality of connecting pipes 14 are arranged on the lower surface of the storage oil tank 2 through the plurality of second one-way valves 15. A fuel supply pipe 8 is arranged on the lower surface of the storage oil tank 2 through the plurality of connecting pipes 14. A main oil pipe 12 is fixedly connected to one side of the outer wall of the fuel supply pipe 8, and a main valve 11 is arranged on one side of the outer wall of the main oil pipe 12. By opening the main valve 11 on the outer wall of the main oil pipe 12, the cooling oil can be transported along the inner wall of the main oil pipe 12 through the external oil supply pressure. The main oil pipe 12 is connected to the fuel supply pipe 8, and the fuel supply pipe 8 is connected to the storage oil tank 2 through the plurality of connecting pipes 14, so that the oil transported inside the main oil pipe 12 enters the storage oil tank 2 along the fuel supply pipe 8 and the plurality of connecting pipes 14. By arranging the plurality of connecting pipes 14, the pressure during external oil transportation is reduced. By arranging the storage oil tank 2 as a transitional oil storage mechanism, it can ensure that the oil output by the circulation pump 5 is uniform and smooth. At the connection between the connecting pipe 14 and the storage oil tank 2, a second one-way valve 15 is arranged, and the second one-way valve 15 is set to only allow oil to enter and not exit, so as to effectively prevent the cooling oil inside the storage oil tank 2 from flowing back into the fuel supply pipe 8 when the external oil supply stops operating, so that the circulation pump 5 transports the oil inside the storage oil tank 2 with uniform and smooth oil output, cools the processing mechanism, and achieves the effect of facilitating the guarantee of uniform and smooth oil output.
[0021] Refer to Figure 1 , a drain pipe 9 is fixedly connected to one side of the lower surface of the storage oil tank 2, and a valve 10 is arranged on one side of the outer wall of the drain pipe 9. By installing the drain pipe 9 at the bottom of the storage oil tank 2 and installing a valve 10 on the outer wall of the drain pipe 9, opening the valve 10 can discharge the oil inside the storage oil tank 2, avoiding the oil inside the storage oil tank 2 being used for too long and affecting the cooling effect.
[0022] Refer to Figure 2 and Figure 3, on one inner side of the workbench 1, a processing table 17 is fixedly connected. A filter screen 16 is arranged corresponding to the outer wall of the processing table 17 inside the workbench 1. On one side of the side surface of the workbench 1, an oil outlet pipe 18 is fixedly connected. By installing the filter screen 16 around the processing table 17, since debris and other impurities will be generated by the workpiece on the top of the processing table 17, the impurities are filtered out through the filter screen 16 to ensure the cleanliness of the cooling oil.
[0023] Refer to Figure 1 , Figure 2 and Figure 3 , on one side of the side surface of the workbench 1, an oil supply pump 3 is fixedly connected. A plurality of hoses 4 are communicated with the outer wall of the oil supply pump 3. Among them, the model of the oil supply pump 3 is preferably KWT-XCLYB type, and the oil supply pump 3 is externally connected to a power supply and a control switch during use. The oil supply pump 3 is connected to the oil outlet pipe 18 through a hose 4 on one side, and the oil supply pump 3 is connected to an oil supply pipe 8 through a hose 4 on the other side. The oil outlet pipe 18 and the oil supply pipe 8 are communicated through the hoses 4 on both sides of the oil supply pump 3. The oil outlet pipe 18 is communicated with the inside of the workbench 1, so that the filtered oil inside the workbench 1 can flow out through the oil outlet pipe 18. The oil inside the workbench 1 is transported into the oil supply pipe 8 through the oil supply pump 3, and then the oil can be reused, effectively saving production costs.
[0024] Refer to Figure 3 , a first one-way valve 13 is arranged on the outer wall of the oil supply pipe 8 corresponding to one side of the hose 4. One inner side of the inner wall of the workbench 1 is set as a slope 19. A first one-way valve 13 is installed at the connection of the oil supply pipe 8 and the hose 4 on one side, and the first one-way valve 13 is set to only allow oil to enter and not exit, so that the filtered oil in the workbench 1 can be transported into the storage tank 2. And after the work is over, the oil will not flow back into the hose 4. By setting the inner wall of the workbench 1 as a slope 19, it plays a guiding role for the filtered oil, facilitating the reuse of the filtered oil, achieving the effect of facilitating the recycling of oil and reducing costs.
[0025] The implementation principle of the oil supply device of a spark machine in an embodiment of this application is as follows: When the spark machine processes a workpiece fixed on the top of the processing table 17, by opening the main valve 11 on the outer wall of the main oil pipe 12, the cooling oil can be transported along the inner wall of the main oil pipe 12 through the external oil supply pressure. The main oil pipe 12 is connected to the oil supply pipe 8, and the oil supply pipe 8 is connected to the oil storage tank 2 through several connecting pipes 14, so that the oil transported inside the main oil pipe 12 enters the oil storage tank 2 along the oil supply pipe 8 and several connecting pipes 14. Subsequently, the cooling oil inside the oil storage tank 2 is transported into the spray oil pipe 6 by the circulation pump 5 and sprayed out from inside the nozzle 7, so as to cool the mechanism being processed. At the same time, by installing the filter screen 16 around the processing table 17, since debris and other impurities will be generated by the workpiece on the top of the processing table 17, the impurities are filtered out by the filter screen 16 to ensure the cleanliness of the cooling oil. The oil outlet pipe 18 and the oil supply pipe 8 are connected through the hoses 4 on both sides of the oil supply pump 3, and then the oil inside the workbench 1 is transported into the oil supply pipe 8 by the oil supply pump 3, so that the oil can be reused, effectively saving production costs.
