Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool equipment, and specifically relates to a CNC machine tool with a circulating cooling structure. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. It can automatically perform machining according to pre-programmed instructions. The cooling components of CNC machine tools are designed to reduce the temperature of the cutting tools and workpieces during machining, improve machining accuracy, reduce tool wear, protect machine tool components, and ensure machining stability. Currently, most CNC machine tool cooling components have some drawbacks. The main drawback is limited cooling effect, making it difficult to continuously and stably reduce machining temperature. Due to a lack of circulation, the coolant cannot efficiently remove heat, leading to accelerated tool wear, potentially decreasing machining accuracy as temperature rises, and possibly causing thermal deformation of the workpiece, affecting product quality. These drawbacks are mainly caused by the inability to continuously circulate and refresh the coolant, resulting in the gradual accumulation of heat. Conventional solutions generally involve increasing the coolant flow rate or frequently changing the coolant. However, increasing the coolant flow rate increases costs and may put pressure on machine tool seals, potentially causing coolant splashing and affecting the working environment. Frequent coolant changes are time-consuming and labor-intensive, increasing production costs and downtime, and may also lead to resource waste and environmental pollution. Therefore, a new structure is needed to solve the above-mentioned technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a CNC machine tool with a circulating cooling structure to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: A CNC machine tool with a circulating cooling structure includes: a machine tool assembly and a cooling assembly. The right side of the machine tool assembly is equipped with a cooling assembly for circulating cooling of the cutting tool. The machine tool assembly includes: a housing and a cover. A CNC panel is installed on the front surface of the housing. The cover is hinged to the front surface of the housing. A machining plate is installed inside the housing. A door panel is hinged to the front surface of the housing. A collection assembly is installed inside the housing. The collection assembly includes: an inclined plate and a filter screen. An inclined plate is installed below the machining plate. A filter screen is installed below the inclined plate through a collection cavity. The cooling assembly includes: a pump component, a cooling component, and a booster pump. The pump component is connected to the cooling component through a pipe. The cooling component is connected to the booster pump through a pipe.

[0005] In a preferred embodiment, a support leg is installed at each of the four corners of the lower surface of the housing, the front surface of the housing is designed with a slope, a CNC panel is installed on the slope of the front surface of the housing, and a cover is damped and sealed at the slope of the front surface of the housing.

[0006] In a preferred embodiment, the surface of the cover is equipped with an observation window and a handle. A work plate is installed below the cover. The upper surface of the work plate is provided with a working area and a grid area. The lower edge of the front surface of the cover is hinged to a door panel by a latch. In use, the inclined plate of the collection component can guide the coolant and impurities to the collection chamber, preventing them from scattering randomly inside the machine tool. This helps to keep the inside of the machine tool clean and reduce hygiene problems and safety hazards caused by the accumulation of impurities.

[0007] In a preferred embodiment, an inclined plate with a 25-degree angle (higher on the right and lower on the left) is installed below the working plate via the outer shell. The end of the inclined plate away from the outer shell is positioned above the collection chamber. A filter screen is installed on the upper side inside the collection chamber, and a magnetic suction plate is installed at the bottom inside the collection chamber.

[0008] In a preferred embodiment, an extraction tube is installed on the right side surface of the collection chamber, with the extraction end of the extraction tube located at the bottom inside the collection chamber. The extraction tube penetrates the right side surface of the outer shell, and the end of the extraction tube away from the collection chamber is connected to the inlet end of the pump.

[0009] In a preferred embodiment, the outlet end of the pump component is connected to the inlet end of the cooling component via a pipe, the outlet end of the cooling component is connected to the inlet end of the booster pump via a pipe, and the outlet end of the booster pump is equipped with three hoses, with three spray pipes installed at the ends of the three hoses away from the booster pump via mounting components.

[0010] In a preferred embodiment, the three spray pipes have the same structure, and multiple nozzles are evenly installed on the outer surface of each of the three spray pipes. The spraying end of the nozzle is aligned with the working area on the upper surface of the work plate. During use, the tool will heat up rapidly due to friction with the workpiece and cutting heat during the machining process. The cooling component can remove the heat from the tool in time through circulating cooling, thereby reducing the working temperature of the tool. This can significantly reduce tool wear and extend the tool's service life.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: By setting a collection component, a collection component is installed inside the outer shell. The collection component includes an inclined plate and a filter screen. An inclined plate is installed below the working plate, and a filter screen is installed below the inclined plate through the collection chamber. During use, the inclined plate of the collection component can guide the coolant and impurities to flow into the collection chamber, preventing them from scattering randomly inside the machine tool. This helps to keep the inside of the machine tool clean and reduce hygiene problems and safety hazards caused by the accumulation of impurities. At the same time, the filter screen inside the collection chamber can effectively filter out the chips and metal powder impurities carried by the coolant during circulation, preventing them from entering the coolant component.

[0012] By incorporating a cooling assembly, a circulating cooling system for the cutting tool is installed on the right side of the machine tool assembly. This assembly includes a pump, a cooling unit, and a booster pump. The pump is connected to the cooling unit via pipes, and the cooling unit is connected to the booster pump via pipes. During operation, the cutting tool rapidly heats up due to friction with the workpiece and cutting heat. The cooling assembly, through circulating cooling, effectively removes this heat, reducing the tool's operating temperature. This significantly reduces tool wear and extends its service life. Compared to a machine tool without a cooling assembly, a tool cooled through circulation can maintain its sharpness and cutting performance for a longer period, reducing the frequency of tool replacements and lowering production costs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a CNC machine tool with a circulating cooling structure, including: a machine tool assembly and a cooling assembly. The right side of the machine tool assembly is equipped with a cooling assembly for circulating cooling of the cutting tool. The machine tool assembly includes: a housing 100 and a cover 120. A CNC panel 110 is installed on the front surface of the housing 100. The cover 120 is hinged to the front surface of the housing 100. A processing plate is installed inside the housing 100. A door panel 150 is hinged to the front surface of the housing 100. A collection assembly is installed inside the housing 100. The collection assembly includes: an inclined plate 210 and a filter screen 220. An inclined plate 210 is installed below the work plate 140. A filter screen 220 is installed below the inclined plate 210 through a collection cavity 200. The cooling assembly includes: a pump component 300, a cooling component 310, and a booster pump 320. The pump component 300 is connected to the cooling component 310 through a pipe. The cooling component 310 is connected to the booster pump 320 through a pipe.

[0023] Please see Figures 1 to 4 As the first embodiment of this utility model: a support leg 130 is installed at each of the four corners of the lower surface of the outer shell 100; the front surface of the outer shell 100 is designed with a slope; a CNC panel 110 is installed on the slope of the front surface of the outer shell 100; and a cover 120 is damped and sealed hinged to the slope of the front surface of the outer shell 100.

[0024] The surface of the cover 120 is equipped with an observation window and a handle. The bottom of the outer shell 100 is equipped with a work plate 140. The upper surface of the work plate 140 is provided with a work area and a grid area. The lower edge of the front surface of the outer shell 100 is hinged to a door panel 150 by a latch.

[0025] Below the working plate 140, a sloping plate 210 with a right-high and left-low angle of 25 degrees is installed through the outer shell 100. The end of the sloping plate 210 away from the outer shell 100 is set above the collection chamber 200. A filter screen 220 is installed on the upper side inside the collection chamber 200, and a magnetic suction plate 230 is installed at the bottom inside the collection chamber 200.

[0026] An extraction tube 240 is installed on the right side surface of the collection chamber 200. The extraction end of the extraction tube 240 is located at the bottom inside the collection chamber 200. The extraction tube 240 penetrates the right side surface of the outer shell 100. The end of the extraction tube 240 away from the collection chamber 200 is connected to the inlet end of the pump.

[0027] When in use, the user first opens the cover 120, then places the workpiece to be processed in the working area on the upper surface of the work plate 140, and then closes the cover 120 to perform the processing operation through the CNC panel 110 (the specific processing operation, processing steps and principles are existing technologies and will not be described in detail here). When processing, the collecting chamber 200 is pre-filled with cooling oil that needs to be circulated and cooled. During processing, the user can cool the processing position through the cooling component. During use, the inclined plate 210 of the collecting component can guide the coolant and impurities to the collecting chamber 200, preventing them from scattering randomly inside the machine tool. This helps to keep the inside of the machine tool clean and reduce hygiene problems and safety hazards caused by the accumulation of impurities. At the same time, the filter screen 220 inside the collecting chamber 200 can effectively filter out the chips and metal powder impurities carried by the coolant during circulation, preventing them from entering the cooling component.

[0028] Please see Figures 1 to 4 As a second embodiment of the present invention: the outlet end of the pump component 300 is connected to the inlet end of the cooling component 310 through a pipe, the outlet end of the cooling component 310 is connected to the inlet end of the booster pump 320 through a pipe, and the outlet end of the booster pump 320 is equipped with three hoses, and the end of the three hoses away from the booster pump 320 is equipped with three spray pipes 340 through the mounting component 330.

[0029] The three spray pipes 340 have the same structure, and multiple nozzles are evenly installed on the outer surface of the three spray pipes 340 respectively. The spraying end of the nozzle is aligned with the working area on the upper surface of the working plate 140.

[0030] During operation, when machining is being performed inside the housing 100 of the CNC machine tool, heat is generated when the tool contacts the workpiece, and metal chips are produced during machining. At this time, the user can activate the pump 300 inside the cooling assembly, and then extract the cooling oil from the collection chamber 200 through the extraction pipe 240, discharging it into the cooling component 310 to cool the oil. The cooling component 310 then discharges the cooled oil through a pipe into the booster pump 320, which then discharges the cooling oil at high pressure into a hose, and finally from the hose into the spray pipe. Inside the 340, cooling oil is finally sprayed out by the nozzles on the outer surface of the spray pipe 340 to cool the workpiece being processed. When the cooling oil enters the upper surface of the work plate 140, the sprayed cooling oil falls onto the grid area on the upper surface of the work plate 140, thus entering the collection chamber 200 through the grid area. When the cooling oil enters the collection chamber 200 through the grid area, it is first filtered by the filter screen 220 inside the collection chamber 200, thus intercepting the debris inside the cooling oil. Then, the uninterrupted metal filings enter the collection chamber 200. The iron filings are drawn to the bottom of the collection chamber 200 and magnetically attracted by the magnetic plate 230 at the bottom, preventing them from floating inside the cooling oil. They then enter the cooling assembly. While the collection chamber 200 is collecting the cooling oil, the cooling assembly re-extracts the oil through the same steps (the cooling components 310, pump 300, and booster pump 320 inside the cooling assembly are all existing technologies; any commercially available model can be selected, as long as it meets the equipment's requirements. Their specific working principles and structures are not detailed here). The oil is then discharged, forming a cycle. After a period of use, the user can... Open the door panel 150 to clean the inside of the collection chamber 200 and the surface of the filter screen 220, and replace the cooling oil (when replacing the cooling oil, simply pour it directly into the mesh area). During use, the cutting tool will rapidly heat up due to friction and cutting heat with the workpiece. The cooling component can remove the heat from the cutting tool in time through circulation cooling, reducing the working temperature of the cutting tool. This can significantly reduce tool wear and extend the tool's service life. Compared with the case without a cooling component, the cutting tool with circulation cooling can maintain its sharpness and cutting performance for a longer period of time, reducing the frequency of tool replacement and lowering production costs.

[0031] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
