Description

Technical Field

[0001] The utility model relates to the technical field of machine tool cooling, in particular to a cooling device for a numerical control machine tool. Background Art

[0002] A numerical control machine tool, abbreviated as a CNC machine tool, is an automated machine tool equipped with a program control system. This control system can logically process a program with control codes or other symbolic instructions, decode it, represent it in coded numbers, and input it into the numerical control device through an information carrier.

[0003] However, in the prior art, during long-term operation of existing numerical control machine tools, their milling cutters will overheat. At this time, it is necessary to spray coolant to cool them down. However, some numerical control machine tools lack measures to recycle the sprayed coolant, resulting in the inability to recycle the coolant and wasting resources. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art: some numerical control machine tools lack measures to recycle the sprayed coolant, resulting in the inability to recycle the coolant and wasting resources.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a cooling device for a numerical control machine tool, including a numerical control machine tool body. The inner surface of the numerical control machine tool body is fixedly connected with a partition board. And below the partition board inside the numerical control machine tool body, there is a coolant storage tank and a water pump. The output end and the input end of the water pump are both fixedly connected with infusion pipes. One end of the infusion pipe penetrates and is fixedly connected to the coolant storage tank, and the other end penetrates and is fixedly connected to the partition board. One end of the infusion pipe is fixed with a spray head. The inner surface of the coolant storage tank is fixedly connected with an electric telescopic rod. One end of the electric telescopic rod is fixed with a cross plate. One side of the cross plate is fixedly connected with a connecting piece. The partition board is provided with a through hole at a position above the connecting piece. And a vertical column is arranged in the through hole. One end of the vertical column is fixedly connected to the connecting piece, and the other end is fixedly connected to a top ring. A filter screen is fixedly connected to the top ring.

[0006] As a preferred implementation manner, the depth of the through hole is consistent with the total length of the vertical column and the top ring, and the cross-sectional area of the top ring is consistent with the cross-sectional area of the through hole.

[0007] As a preferred implementation manner, a fixed enclosure is fixedly connected to the surface of the partition board near the through hole, and a movable enclosure is snap-connected to one side of the surface of the partition board where the fixed enclosure is located.

[0008] As a preferred implementation manner, a handle is fixedly connected to one side surface of the movable enclosure.

[0009] Compared with the prior art, the advantages and positive effects of the utility model are as follows:

[0010] In the present utility model, the coolant ejected from the nozzle can flow back into the coolant storage tank through the through - holes on the partition plate for recycling. During this period, the filter screen will filter the debris generated during the machining of the numerical control machine tool body, effectively preventing sundries from entering the coolant storage tank along with the coolant. In this way, the cooling water can be recycled, reducing waste. At the same time, under the reciprocating telescopic movement of the electric telescopic rod, the connecting piece is driven to strike the partition plate, thereby causing the filter screen to oscillate, effectively avoiding the phenomenon of blockage of the filter screen due to debris.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment 1

[0019] As Figures 1-4As shown in the figure, the present utility model provides a technical solution: a cooling device for a numerical control machine tool, including a numerical control machine tool body 1. The inner surface of the numerical control machine tool body 1 is fixedly connected with a partition plate 2. The partition plate 2 serves to divide the interior of the numerical control machine tool body 1 into upper and lower parts. And inside the numerical control machine tool body 1, below the partition plate 2, there is a coolant storage tank 3 and a water pump 4. Both the output end and the input end of the water pump 4 are fixedly connected with infusion pipes 5. And one end of the infusion pipe 5 penetrates and is fixedly connected to the coolant storage tank 3, and the other end penetrates and is fixedly connected to the partition plate 2. One end of the infusion pipe 5 is fixed with a spray head 6. The coolant storage tank 3 is used to store coolant. With the help of the water pump 4 and the infusion pipes 5, the coolant in the coolant storage tank 3 is pumped to the spray head 6 and sprayed onto the milling cutter on the numerical control machine tool body 1, achieving the effect of cooling the milling cutter. The inner surface of the coolant storage tank 3 is fixedly connected with an electric telescopic rod 7. And one end of the electric telescopic rod 7 is fixed with a cross plate 8. One side of the cross plate 8 is fixed with a connecting piece 9. Through the reciprocating telescopic movement of the electric telescopic rod 7, the cross plate 8 drives the connecting piece 9 to strike the partition plate 2 back and forth, thereby causing the filter screen 12 to oscillate, effectively avoiding the phenomenon of blockage of the filter screen 12 due to debris. At the position above the connecting piece 9 on the partition plate 2, there is an opening, and a vertical column 10 is arranged in the opening. One end of the vertical column 10 is fixedly connected to the connecting piece 9, and the other end is fixedly connected to a top ring 11. With the help of the vertical column 10 and the top ring 11, the filter screen 12 is lifted to make one end close to the opening, facilitating the subsequent cleaning of the debris on the filter screen 12. The top ring 11 is fixedly connected with a filter screen 12. The filter screen 12 serves to filter the debris generated during the processing of the numerical control machine tool body 1, effectively preventing foreign objects from entering the coolant storage tank 3 along with the coolant.

[0020] Embodiment 2

[0021] As Figures 1-4 shown, the depth of the opening is consistent with the total length of the vertical column 10 and the top ring 11, and the cross-sectional area of the top ring 11 is consistent with the cross-sectional area of the opening. This can effectively reduce the gap between the top ring 11 and the opening, reducing the situation where debris enters the coolant storage tank 3 through the gap. At the same time, when the electric telescopic rod 7 extends, it also makes the filter screen 12 flush with the partition plate 2, making it more convenient to clean the debris on its surface. On the surface of the partition plate 2 near the opening, there is a fixed enclosure 13 fixedly connected, and on one side of the fixed enclosure 13 on the surface of the partition plate 2, there is a movable enclosure 14 snap-fitted. With the help of the fixed enclosure 13 and the movable enclosure 14, the opening part on the partition plate 2 is blocked, allowing more coolant to flow into the opening. One side surface of the movable enclosure 14 is fixedly connected with a handle 15. With the help of the handle 15, it is convenient to pull out the movable enclosure 14, and the debris on the partition plate 2 can be swept and scraped to one side through the pulled-out movable enclosure 14, playing an auxiliary cleaning role.

[0022] Working principle:

[0023] As Figures 1-4 shown, when the utility model is in use, when it is necessary to cool the milling cutter on the numerical control machine tool body 1, the user first turns on the water pump 4. The water pump 4 pumps out the coolant stored in the coolant storage tank 3 and transports it to the nozzle 6 through the infusion pipe 5, so that the nozzle 6 sprays towards the milling cutter to achieve the effect of cooling the milling cutter.

[0024] The sprayed coolant will flow down to the partition plate 2. With the help of the enclosure of the fixed enclosure plate 13 and the movable enclosure plate 14, the coolant can flow into the through holes of the partition plate 2 more concentratedly and then enter the coolant storage tank 3. While cooling the milling cutter, the electric telescopic rod 7 also needs to be turned on to make the electric telescopic rod 7 perform periodic telescopic movements, so that the cross plate 8 drives the connecting piece 9 to strike the partition plate 2 back and forth, causing the vertical column 10, the top ring 11 and the filter screen 12 to vibrate, effectively avoiding the situation that the filter screen 12 is blocked due to the accumulation of debris filtered out by the filter screen 12, and enabling the coolant to flow smoothly downward through the filter screen 12.

[0025] The above is only the preferred embodiment of the utility model, and it is not a limitation of the utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the utility model still belong to the protection scope of the technical solution of the utility model.
