Description

Technical Field

[0001] This utility model belongs to the field of drill bit cooling technology, and in particular relates to a drill bit coolant circulation filtration device. Background Technology

[0002] A drill bit is a rotating tool with a cutting edge, commonly used to make holes in the surface of objects.

[0003] Because drill bits generate a lot of heat during operation, they are prone to overheating and breakage. Therefore, existing technologies, such as the patent application number CN202222496159.X, disclose a cooling device for CNC machine tool drill bits. When the drill bit stops working, the slider is moved to adjust the starting point of the nozzle's movement. Then, motor two is turned on to drive the fan, followed by motor one, which controls the nozzle to move up and down to spray coolant onto the drill bit for rapid cooling. After this, both motors are turned off, the slider is moved to contact the fixing block, and nut two is rotated to fix it, preventing the drill bit from being blocked by the nozzle during operation. This device is simple and convenient to use and greatly improves the cooling speed of the drill bit.

[0004] Although the aforementioned patent allows for the spraying of coolant onto the drill bit surface for external cooling, this cooling method only cools the outside of the drill bit and cannot cool the inside. Consequently, as the drill bit is used, the internal heat cannot be dissipated quickly, leading to overheating and breakage.

[0005] Therefore, how to provide a drill bit coolant circulation filtration device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The diagram shown is a structural schematic of a drill bit coolant circulation filtration device according to an embodiment of the present invention, comprising:

[0034] Connector 1;

[0035] The drill bit body 2 is movably installed in the middle of the connecting seat 1 and has a cooling structure to cool the inside of the drill bit body 2.

[0036] The collar 3 is slidably disposed on the surface of the drill bit body 2;

[0037] Connecting plate 4 is fixedly installed at both ends of collar 3, and a water filter box 5 is fixedly connected to its rear side;

[0038] Positioning slide plate 6 is slidably positioned on the front side of water filter tank 5;

[0039] The circulating structure is installed on the surface of the water filter tank 5 and the collar 3, and is movably connected to the cooling structure to circulate and cool.

[0040] In this embodiment of the utility model, when in use, a collar 3 is slidably set on the connecting seat 1, and a water filter box 5 is connected to the outside of the collar 3 through a connecting plate 4, so that the water filter box 5 can rise and fall synchronously with the connecting seat 1. Then, a circulation structure is set on the connecting seat 1 and the water filter box 5, and a cooling structure is set inside the drill bit body 2. In the cooperation of the circulation structure, the inside of the drill bit body 2 is cooled down, so as to avoid the situation of overheating and breakage inside the drill bit body 2.

[0041] like Figure 2 , Figure 3 and Figure 6 As shown, in a preferred embodiment of the present invention, a cooling tank 7 is provided at the lower end of the water filter tank 5, and the bottom of the cooling tank 7 is movably connected to the circulation structure. A filtration structure is also provided at the upper end of the water filter tank 5.

[0042] The filtration structure includes a positioning plate 25, a second top rod 28, and a filter plate 29. The filter plate 29 is fixedly installed in the middle of the water filter tank 5, and an opening 23 is provided in the middle of the top. The positioning plate 25 is arranged in a circumferential array inside the opening 23, and a conical filter cover 24 is fixedly installed at the inner end. A filter debris box 20 is inserted into the middle of the filter plate 29, and an inclined groove 22 is arranged in an array on the inner side. The second top rod 28 is arranged in an array at the bottom of the filter plate 29 and movably abuts against the top of the filter debris box 20. A first top rod 26 is fixedly installed on the top of the second top rod 28, and a baffle 27 is fixedly installed on the top of the first top rod 26 through the surface of the positioning plate 25.

[0043] In this embodiment of the invention, when in use, impurities in the hot coolant are intercepted by the conical filter cover 24 and then enter the impurity box 20 through the opening 23. Subsequently, clean coolant enters the cooling tank 7 through the conical filter cover 24, the filter plate 29, and the impurity box 20. Then, the impurity box 20 is pulled out, thereby causing the second push rod 28 to lose its restraint. Then, under the weight of the baffle 27 and the first push rod 26, the baffle 27 descends and blocks the opening 23, thereby preventing impurities from entering the cooling tank 7 and causing the water pump in the cooling tank 7 to become clogged.

[0044] Meanwhile, by setting a filter structure at the upper end of the water filter tank 5, the coolant in the water filter tank 5 can be filtered, thereby preventing impurities from entering the cooling tank 7 at the lower end of the water filter tank 5, which would cause impurities to enter the circulation structure and cooling structure, resulting in blockage of the circulation structure and cooling structure. Furthermore, impurities can be cleaned during operation to prevent excessive accumulation of impurities, which would affect the normal filtration of the coolant.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in a preferred embodiment of this utility model, the circulation structure includes an outlet pipe 9, an inlet pipe 10, an inlet interface 11, a first temporary water tank 12, an inlet chamber 13, a second temporary water tank 18, an outlet chamber 19, and an outlet interface 21. The inlet chamber 13 and the outlet chamber 19 are symmetrically located on both sides of the connecting seat 1 and are movably connected to the cooling structure. The first temporary water tank 12 is located at the top of the inlet chamber 13. The inlet interface 11 is fixedly installed on the left side of the collar 3 and is slidably connected to the first temporary water tank 12. The second temporary water tank 18 is located at the top of the outlet chamber 19. The outlet interface 21 is fixedly installed on the right side of the collar 3 and is slidably connected to the second temporary water tank 18. The inlet pipe 10 is movably installed on the outside of the inlet interface 11 and is fixedly connected to the bottom of the filter tank 5. The outlet pipe 9 is movably installed on the outside of the outlet interface 21 and is fixedly connected to the top of the filter tank 5.

[0046] In this embodiment of the utility model, when in use, the water pump of the inlet pipe 10 is started, and the coolant at the lower end of the filter tank 5 is transferred to the first temporary water tank 12 through the water inlet interface 11. Then, it enters the drill bit body 2 through the water inlet cavity 13, so that the heat inside the drill bit body 2 is exchanged with the water, and then the hot coolant enters the water outlet cavity 19, and then through the second temporary water tank 18, so that it enters the water outlet interface 21 and then enters the water outlet pipe 9, so that the hot coolant enters the top of the filter tank 5 and is sprayed out.

[0047] By setting up a circulation structure, the heat inside the drill bit body 2 is circulated out, thereby realizing the recycling of coolant, reducing coolant waste and dissipating heat through circulation.

[0048] like Figure 2 As shown, in a preferred embodiment of the present invention, the cooling structure includes a first circulating water tank 14, a first cooling water cavity 15, a second cooling water cavity 16, and a second circulating water tank 17. The first circulating water tank 14 and the second circulating water tank 17 are symmetrically opened on both sides of the upper end of the drill bit body 2. The first cooling water cavity 15 and the second cooling water cavity 16 are arranged in an array from the inside to the outside at the bottom of the first circulating water tank 14 and the second circulating water tank 17.

[0049] In this embodiment of the present invention, when in use, the coolant enters the first cooling water chamber 15 and the left end of the second cooling water chamber 16 through the first circulating water tank 14, and then enters the second cooling water chamber 16 from the right end of the first cooling water chamber 15 and the second cooling water chamber 16, thereby carrying away the heat inside the drill bit body 2, thereby cooling the inside of the drill bit body 2.

[0050] like Figure 3 As shown, in a preferred embodiment of the present invention, a cooling plate 8 is installed in an array at the bottom of the cooling tank 7, and the cooling plate 8 is a heat exchange copper plate.

[0051] In this embodiment of the invention, when in use, a cooling plate 8 is arrayed at the bottom of the cooling tank 7, and the cooling plate 8 is made of heat exchange copper plate, so that the cooling tank 7 can be heat exchanged, thereby keeping the temperature of the coolant in the cooling tank 7 at a low temperature.

[0052] like Figure 3 and Figure 6 As shown, in a preferred embodiment of the present invention, the front side of the bottom of the inclined groove 22 is inclined, and the outer side of the second push rod 28 is provided with an inclined surface corresponding to the inclined surface of the inclined groove 22.

[0053] In this embodiment of the utility model, when in use, by tilting the front side of the bottom of the inclined groove 22 and providing an inclined surface on the outer side of the second push rod 28 corresponding to the inclined surface of the inclined groove 22, the inclined groove 22 can be lifted up when it comes into contact with the second push rod 28.

[0054] like Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the inner diameter of the baffle 27 is equal to the outer diameter of the bottom of the conical filter cover 24, and the outer diameter of the baffle 27 is equal to the inner diameter of the opening 23.

[0055] In this embodiment of the utility model, when in use, by making the inner diameter of the baffle 27 equal to the outer diameter of the bottom of the conical filter cover 24, and the outer diameter of the baffle 27 equal to the inner diameter of the opening 23, the opening 23 can be blocked when the baffle 27 descends.

[0056] The present invention provides a drill bit coolant circulation filtration device in the above embodiments. When the drill bit body 2 is installed in the middle of the connecting seat 1, when the connecting seat 1 is raised and lowered, the water filter box 5 on the surface of the positioning slide plate 6 will be raised and lowered through the connecting plate 4, thereby facilitating the drill bit body 2 to drill holes.

[0057] During drilling, the water pump in the inlet pipe 10 is started, and the coolant in the cooling tank 7 at the lower end of the filter tank 5 is transferred to the first temporary water tank 12 through the water inlet interface 11. Then, it enters the first circulating water tank 14 through the water inlet chamber 13, so that the coolant enters the first cooling water chamber 15 and the left end of the second cooling water chamber 16 through the first circulating water tank 14, and then enters the second circulating water tank 17 from the right end of the first cooling water chamber 15 and the second cooling water chamber 16. This allows the heat inside the drill bit body 2 to exchange with the water, so that the hot coolant enters the outlet chamber 19, and then enters the second temporary water tank 18, thus exiting through the outlet interface 21 and then into the outlet pipe 9, so that the hot coolant enters the top of the filter tank 5 and is sprayed out.

[0058] Then, impurities generated by aging in the hot coolant are intercepted by the conical filter cover 24 and enter the impurity box 20 through the opening 23. Subsequently, the clean coolant enters the cooling tank 7 through the conical filter cover 24, the filter plate 29 and the impurity box 20. The cooling tank 7 exchanges heat with the outside through the cooling plate 8, thereby reducing the temperature of the coolant in the cooling tank 7.

[0059] When it is necessary to clean the filter box 20, the filter box 20 is pulled out of the water filter tank 5, so that the second push rod 28 is unrestrained. Then, under the weight of the baffle 27 and the first push rod 26, the baffle 27 will fall down and block the opening 23, thereby preventing impurities from entering the cooling tank 7 and causing the water pump in the cooling tank 7 to become blocked.

[0060] The new filter box 20 is then inserted into the water filter tank 5, so that the filter box 20 uses its inner inclined groove 22 to lift the second push rod 28, which in turn causes the first push rod 26 to drive the baffle 27 to lift, thus exposing the opening 23, and continuing to collect and filter impurities in the coolant.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
