[0002] High-precision CNC machine tools are core equipment in modern manufacturing. They integrate the achievements of multiple disciplines, including mechanical manufacturing technology, automation control technology, computer technology, and precision measurement technology. This enables them to perform various machining operations such as precise cutting, drilling, and milling on workpieces. They can automatically and accurately complete the machining tasks of complex parts according to pre-set program instructions. During the operation of high-precision CNC machine tools, the machining head generates a lot of heat due to the high-speed cutting operation on the workpiece. If this heat cannot be dissipated in a timely and effective manner, it will cause expansion and deformation of the machine tool and the workpiece, resulting in a reduction in the machining quality of parts and an increase in the scrap rate.

[0003] Traditional high-precision CNC machine tools use industrial fans to cool them down, thus preventing excessive heat buildup that could damage the machine's performance. However, this method has limited effectiveness in dissipating heat from deep within the machine and makes it difficult to precisely control the temperature of critical components. Furthermore, because the workpieces on the machine tool are constantly moving, the industrial fans cannot adapt well to the dynamic changes in the position of the machining head and the workpiece during operation, resulting in insufficient localized heat dissipation and significant temperature fluctuations, which affect the stability of the machine tool's machining accuracy.

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.

[0032] Reference Figures 1-4 The present invention provides an embodiment of a high-precision CNC machine tool heat dissipation device, comprising a machine tool bed 1 and multiple support legs 6. A machining moving gantry 2 is fixedly installed on the top left side of the machine tool bed 1, and a machining head 3 is slidably connected to the right side of the machining moving gantry 2. A heat dissipation mechanism 4 is provided at the bottom of the machine tool bed 1. The heat dissipation mechanism 4 is used to reduce the temperature of the working area when the equipment is working. Movable mechanisms 5 are provided on the outside of the front left and right support legs 6 and the rear left and right support legs 6. Multiple movable mechanisms 5 are used to facilitate the adjustment of the position of the equipment.

[0033] The heat dissipation mechanism 4 includes a movable plate 401, which is slidably connected inside the machining moving gantry 2. Its position can be flexibly adjusted according to machining needs, ensuring comprehensive and precise heat dissipation. A workpiece fixing plate 402 is fixedly connected to the top of the movable plate 401, providing a stable foundation for machining. A carrier plate 403 is fixedly connected to the bottom of the machine tool bed 1, providing a reliable support platform for the components of the heat dissipation mechanism 4. A cooling water tank 404 is fixedly connected to the top left end of the carrier plate 403, storing coolant and absorbing heat through thermal conduction to effectively reduce the temperature of the machine tool's working area. A water pump 405 is fixedly installed in the center of the top of the carrier plate 403, providing power to circulate the coolant and ensuring continuous and efficient heat dissipation. The output end of the water pump 405 is connected to the right side of the cooling water tank 404, facilitating the output and delivery of water from the pump 405 to the cooling water tank 404. A return water tank 406 is fixedly connected to the top right end of the carrier plate 403, allowing the recovery of cooled water. The coolant is naturally cooled and circulated. The input end of the water pump 405 is connected to the top of the carrier plate 403 to ensure a stable source of coolant. The front and rear sides of the radiator tank 404 and the front and rear sides of the top of the return tank 406 are connected to transmission pipes 407, which can realize the smooth transmission of coolant between various components and ensure the continuity of the heat dissipation process. The adjacent sides of the multiple transmission pipes 407 are connected to telescopic pipes 408, which can adapt to the movement of the moving plate 401 and ensure that the coolant transmission is not affected by position changes. The moving plate 401 has a flow channel 409 inside to provide a flow channel for coolant, so that heat can be fully absorbed. The input ends of the two telescopic pipes 408 on the left end are connected to the two output ends of the flow channel 409, and the output ends of the two telescopic pipes 408 on the right end are connected to the two input ends of the flow channel 409, realizing the circulation of coolant between the flow channel 409 and other components, efficiently removing heat and maintaining the machine tool's good heat dissipation state.

[0034] Reference Figure 1 and Figure 5The moving mechanism 5 includes two L-shaped fixing plates 501, which are fixedly connected to the outside of the front left and right end support legs 6 and the rear left and right end support legs 6, respectively, providing a stable mounting base for the entire moving mechanism 5 and ensuring the normal operation of subsequent components. A threaded cylinder 502 is fixedly connected between the adjacent L-shaped fixing plates 501, serving as a guide and support structure for the movement of the lead screw 503, ensuring the smoothness of the lead screw 503's movement. The lead screw 503 is internally threaded into the threaded cylinder 502, and the lead screw 503's movement is achieved through threaded engagement. The machine tool moves vertically in a straight line, thereby controlling the lifting and lowering of the caster wheel 504; the lead screw 503 passes through the middle of the two L-shaped fixed plates 501, facilitating precise displacement of the lead screw 503 along a fixed path; the bottom end of the lead screw 503 is rotatably connected to the caster wheel 504, which contacts the ground when the lead screw 503 descends, allowing the machine tool to move flexibly and adapt to different working position requirements; the top of the lead screw 503 is fixedly connected to a knob 505, allowing the operator to apply rotational force and easily control the movement of the lead screw 503, thereby achieving convenient adjustment of the machine tool position.

[0035] Reference Figure 1 , Figure 3 and Figure 5 A control console 7 is fixedly connected to the rear right side of the top of the machine tool bed 1, providing a centralized area for the operation and control of the machine tool and facilitating the input of various commands by the operator. Multiple control buttons 8 are fixedly connected to the top of the control console 7, which can be used to precisely control various functions of the machine tool, such as start, stop, and parameter adjustment. A temperature gauge 9 is fixedly connected to the front right side of the top of the machine tool bed 1, which is electrically connected to the workpiece fixing plate 402 and can display the temperature at the workpiece fixing plate 402 in real time, allowing the operator to understand the thermal status of the machine tool's working area. Anti-slip pads 10 are fixedly connected to the bottom of multiple support legs 6. The bottoms of the anti-slip pads 10 are designed to be non-slip, effectively increasing the stability of the machine tool when placed and preventing slippage during operation. The displacement occurs in the heat sink 404, which has multiple heat dissipation columns 11 inside. The bottom of the multiple heat dissipation columns 11 all penetrates the bottom of the carrier plate 403, which helps to enhance the heat dissipation efficiency of the heat sink 404 and accelerate the cooling speed of the coolant. The knob 505 has multiple anti-slip grooves 12 equidistantly opened on the outside. The multiple anti-slip grooves 12 are all arc-shaped, which makes it easier for the operator to hold the knob 505 and prevents slippage when applying rotational force. The top of the workpiece fixing plate 402 has multiple fixing holes 13 equidistantly opened, which can be used to firmly fix the workpiece and ensure that the workpiece will not loosen during the processing. The workpiece fixing plate 402 is made of high temperature resistant metal material, which can withstand the high temperature generated during the processing, extend its service life and ensure its structural stability.

[0036] Working Principle: The machine tool bed 1 forms the basic frame of the entire equipment. The machining moving gantry 2 on the top left and its sliding machining head 3 can cut the workpiece. Inevitably, heat is generated during machining. At this time, the heat dissipation mechanism 4 located at the bottom of the machine tool bed 1 starts operating. When the water pump 405 starts, water is drawn from the top of the carrier plate 403 and forcefully transported to the right side of the heat dissipation tank 404. In the heat dissipation tank 404, the water absorbs heat from the machining area, especially the moving plate 401 and the workpiece fixing plate 402, through heat conduction contact with the machine tool bed 1. The water temperature gradually rises. Subsequently, the heated water in the heat dissipation tank 404 flows through the front and rear transmission pipes 407 into the connected telescopic pipe 408, and then into the flow channel 409 inside the moving plate 401. Because the flow channel 409 is located near the heat source, the circulating water inside it can fully absorb the heat from the moving plate 401. The heat on plate 401 and workpiece fixing plate 402 is then transferred to the hot water in the flow channel 409 and flows into the return water tank 406 through the telescopic pipe 408 and transmission pipe 407 at the right end. The return water tank 406 not only provides temporary storage space for the hot water but also helps the hot water to dissipate heat naturally and cool down. It also provides a buffer and regulation function for the stable operation of the entire water circulation system. The water that has been cooled to a certain extent in the return water tank 406 will be drawn back into the cooling water tank 404 by the continuous action of the water pump 405, starting a new cycle. This process is repeated continuously, carrying away and dissipating the heat generated in the processing area, thereby effectively reducing the temperature on the moving plate 401 and workpiece fixing plate 402. This ensures stable temperature control of the CNC machine tool during processing, which is beneficial to improving processing accuracy, reducing processing errors caused by factors such as thermal deformation, and ensuring the efficient and high-precision operation of the machine tool.

[0037] Furthermore, when the position of the CNC machine tool needs to be adjusted, it can be operated through the moving mechanism 5. The L-shaped fixing plates 501 are firmly fixed to the outside of the front left and right end support legs 6 and the rear left and right end support legs 6, respectively, providing a stable installation base and support structure for the entire moving mechanism 5. The threaded cylinder 502, which is fixedly connected between the two adjacent L-shaped fixing plates 501, is the core transmission component. When the operator rotates the knob 505 on the top of the lead screw 503, since the lead screw 503 and the threaded cylinder 502 are threadedly connected, under the rotational force of the knob 505, the lead screw 503 will move up and down linearly along the internal thread of the threaded cylinder 502. When the lead screw 503 moves downward, the universal wheel 504 rotatably connected to its bottom end will gradually... As the lead screw 503 continues to descend closer to the ground, the caster wheel 504 eventually contacts the ground and gradually lifts the machine tool, changing the weight of the machine tool from being supported by the support leg 6 to being supported by the caster wheel 504. At this time, the caster wheel 504 can be used to flexibly move the machine tool on the plane, thus facilitating the adjustment of the equipment's position. When the machine tool moves to the designated position, the knob 505 is turned in the opposite direction, the lead screw 503 moves upward, and the caster wheel 504 gradually leaves the ground. The weight of the machine tool is then borne by the support leg 6 again, and the machine tool is stably placed in the new position, completing the entire position adjustment process. Through this moving mechanism 5, the position movement and adjustment of high-precision CNC machine tools can be easily and accurately realized, meeting different processing layouts and site requirements.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
