Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, and particularly relates to a cutting fluid cooling and filtering device for a numerical control machine tool. Background Technique

[0002] A numerical control machine tool is short for a numerically controlled machine tool, which is an automated machine tool equipped with a program control system. It can send out various control signals through the numerical control device after arithmetic processing to control the actions of the machine tool, and automatically process parts according to the shape and size required by the drawing. The stable operation of the numerical control machine tool is inseparable from the cooling of the cutting fluid for the processed workpiece. The cutting fluid is transported to the nozzle through a liquid pump, and then continuously sprayed onto the processed part and the cutting tool head through the nozzle to achieve the purpose of cooling.

[0003] However, after the cutting fluid of the existing numerical control machine tool is ejected, it will be mixed with the debris of the processed workpiece, and generally it is discharged mixed with the debris, so that the cutting fluid cannot be filtered and recycled, which is relatively wasteful. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that after the cutting fluid of the existing numerical control machine tool is ejected, it will be mixed with the debris of the processed workpiece, and generally it is discharged mixed with the debris, so that the cutting fluid cannot be filtered and recycled, which is relatively wasteful.

[0005] The utility model realizes the above purpose through the following technical solutions: A cutting fluid cooling and filtering device for a numerical control machine tool is provided and is arranged inside the machine tool body. A workbench is also arranged inside the machine tool body. A drain port is opened on one side of the workbench, and a cutting fluid cooling and filtering device is arranged below the drain port. The cutting fluid cooling and filtering device includes a first filter box connected to the drain port. A first filter plate is inclined in the first filter box. A water passing plate is arranged below the first filter plate. The cutting fluid forms a water curtain and drops after passing through the water passing plate to increase the contact area between the cutting fluid and the air. A slag flowing port is opened on the side surface of the first filter box. A second filter box is arranged closely to one side of the first filter box. An inlet slag port and an outlet liquid port are respectively opened on one side surface of the second filter box. A second filter plate is arranged between the inlet slag port and the outlet liquid port.

[0006] Further, the water passing plate is in a check shape, and a long strip-shaped water passing port is opened at the concave hook.

[0007] Further, a plurality of heat dissipation holes are opened on the side surface of the first filter box on one side of the water passing plate, and a blowing fan is installed below the heat dissipation holes. The air outlet of the blowing fan faces the side of the water passing port.

[0008] Further, a liquid storage box is connected to the bottom of the first filter box, and a water pump is arranged on the top surface of the liquid storage box. The water pump conveys the cutting fluid in the liquid storage box back into the machine tool body.

[0009] Further, a support plate for supporting the second filter box is connected to the side surface of the first filter box.

[0010] Further, a slag discharge port is opened on the side surface of the second filter box, and a sealing door is installed at the slag discharge port by means of hinge connection.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The water passing plate in the utility model is in a checkmark shape, and a long strip-shaped water passing port is opened at the concave hook. Thus, when the cutting fluid flows to the water passing port, it falls downward in a water curtain shape, greatly increasing the contact area between the cutting fluid and the air, improving the cooling effect of the cutting fluid. In addition, a plurality of heat dissipation holes are opened on the side surface of the first filter box on one side of the water passing plate. With the use of a blowing fan, the heat dissipation effect of the cutting fluid is further enhanced. The air outlet of the blowing fan blows towards the water passing port side towards the flowing-down cutting fluid, which can accelerate the heat dissipation process of the cutting fluid.

[0013] 2. While filtering the waste residue in the cutting fluid, the first filter plate is inclined by itself. Thus, the waste residue will roll from the slag inlet to the second filter plate under the impact of the cutting fluid. After the second filter plate filters the waste residue again, the cutting fluid flows from the liquid outlet to the water passing plate. Thus, the second filter box plays a role in collecting the waste residue.

[0014] 3. The arrangement of the liquid storage box and the water pump connected to the bottom of the first filter box enables the cutting fluid to be effectively collected and reused. The water pump conveys the cutting fluid in the liquid storage box back into the machine tool body, forming a closed circulation system, reducing the waste of the cutting fluid, and lowering the production cost.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0024] Combined with Figures 1 to 5 A cutting fluid cooling and filtering device for a numerical control machine tool as shown is arranged inside the machine tool body 1. A workbench 2 is also arranged inside the machine tool body 1. A liquid discharge port 3 is opened on one side of the workbench 2. A cutting fluid cooling and filtering device 4 is arranged below the liquid discharge port 3. The cutting fluid cooling and filtering device 4 includes a first filter tank 5 connected to the liquid discharge port 3. A first filter plate 51 is inclinedly arranged inside the first filter tank 5. A water passing plate 52 is arranged below the first filter plate 51. The cutting fluid falls in a water curtain shape after passing through the water passing plate 52 to increase the contact area between the cutting fluid and the air. A slag flow port 53 is opened on the side surface of the first filter tank 5. A second filter tank 6 is arranged closely on one side of the first filter tank 5. A slag inlet 61 and a liquid outlet 62 are respectively opened on one side surface of the second filter tank 6. A second filter plate 63 is arranged between the slag inlet 61 and the liquid outlet 62;

[0025] Among them, the water passing plate 52 is in a check mark shape, and a long strip-shaped water passing port 521 is opened at the concave hook. When the cutting fluid flows into the first filter tank 5 from the drain port 3, after the iron filings and waste residues are filtered by the first filter plate 51, most of the cutting fluid directly flows downward through the filter holes onto the water passing plate 52. Another part of the cutting fluid falls into the second filter tank 6 with the waste residues from the inclined first filter plate 51 and flows to the water passing plate 52 through the second filter plate 63 from the liquid outlet 62. Subsequently, the cutting fluid on the water passing plate 52 flows out downward in a water curtain shape through the long strip-shaped water passing port 521;

[0026] A number of heat dissipation holes 7 are opened on the side surface of the first filter tank 5 on one side of the water passing plate 52. A blower fan 8 is installed below the heat dissipation holes 7, and the air outlet of the blower fan 8 faces the side of the water passing port 521. When the cutting fluid flows out from the water passing port 521, the blower fan 8 is started to blow air on the water curtain-shaped cutting fluid to help it dissipate heat. Subsequently, the hot air is dissipated through the heat dissipation holes 7; Combined Figures 1-2 it can be seen that the heat dissipation holes 7 are located on the opposite side of the wind direction of the blower fan 8. Therefore, when blowing air to dissipate heat from the cutting fluid, the cutting fluid will not splash out from the heat dissipation holes 7;

[0027] The bottom of the first filter tank 5 is connected with a liquid storage box 9. The top surface of the liquid storage box 9 is provided with a water pump 10. The water pump 10 can transport the cutting fluid in the liquid storage box 9 back to the machine tool body 1 through a connecting water pipe, and continue to use the cutting fluid to process the workpiece, thus forming a closed circulation system and reducing the waste of cutting fluid;

[0028] The side surface of the first filter tank 5 is connected with a support plate 11 for supporting the second filter tank 6; A slag discharge port 64 is opened on the side surface of the second filter tank 6, and a sealing door 12 is installed at the slag discharge port 64 by means of hinge connection. When the numerical control machine tool processes the workpiece, the sealing door 12 is in a sealed state. When the processing is paused or completed, the iron filings and waste residues on the first filter plate 51 and the second filter plate 63 can be removed by opening the sealing door 12, thereby reducing the filtration pressure.

[0029] Working principle: When the utility model is in use, a numerical control machine tool is used to process a workpiece. The cutting fluid and the iron filings and waste residues generated during the processing and cutting will flow downward through the drain port 3 into the first filter box 5. Then, after the first filter plate 51 filters the iron filings and waste residues, most of the cutting fluid directly flows downward through the filter holes to the water passing plate 52. Another part of the cutting fluid, along with the waste residues, enters the second filter box 6 through the slag inlet 61 on the inclined first filter plate 51, and after being filtered by the second filter plate 63, enters the water passing plate 52 of the first filter box 5 through the liquid outlet 62. Subsequently, the cutting fluid on the water passing plate 52 flows downward in a water curtain shape through the long strip-shaped water passing holes 521. At this time, the blowing fan 8 is started to blow air to the water curtain-shaped cutting fluid to help it dissipate heat. Then, the hot air is dissipated through the heat dissipation holes 7. Subsequently, the cutting fluid flows into the liquid storage box 9, and finally, the water pump 10 transports the filtered cutting fluid back to the machine tool body 1 through a water pipe for continued use in processing the workpiece.
