Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, specifically to a CNC machine tool with cooling for machine tool structural components. Background Technology

[0002] A CNC machine tool is a machine tool that uses a numerical control system to control motion and machining processes. Compared to traditional manually operated machine tools, CNC machine tools have a higher degree of automation and precision, enabling them to perform complex machining tasks and meet production requirements. The core of a CNC machine tool is the CNC system, which consists of a computer, controller, and sensors. Operators can input commands, use graphical interfaces, or programming languages ​​to translate the requirements of machining tasks into instructions that the CNC system can understand and execute. The CNC system then controls the various motion axes of the machine tool, such as the feed axis and spindle, according to these instructions to achieve precise machining movements.

[0003] For example, CN222711615U discloses a CNC machine tool belonging to the field of hot runner manifold processing technology. It includes a chassis, on which a fixing mechanism, a conveying mechanism, and a recovery mechanism are provided. The fixing mechanism includes a rotating shaft rotatably mounted on the chassis, with a fixed seat fixedly mounted at the end of the shaft. The fixed seat has several sliding holes, and a slider is disposed within each sliding hole. A retainer is fixedly mounted on the slider, and several retainers cooperate with each other. The conveying mechanism includes a conveying table fixedly mounted inside the chassis. By setting up the recovery mechanism, when the suction fan starts, it sucks in and recovers metal scraps and dust generated during processing through a recovery hood and recovery pipe. The sucked-in metal scraps and dust are filtered through filter holes and remain in the recovery box, effectively solving the problem of the chassis being filled with metal scraps and dust, and facilitating subsequent cleaning of the metal scraps and dust.

[0004] When a machine tool is processing, its structural components may absorb excessive heat, which can easily lead to overheating during prolonged processing. This can cause deformation of the machine tool parts, making it difficult to cool the mechanism, and ultimately causing the equipment to overheat and affecting the overall service life of the machine tool. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a CNC machine tool with cooling for machine tool structural components, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a CNC machine tool with cooling for machine tool structural components, including a base, a machine tool fixedly connected to the top of the base, a housing provided at the bottom of the base, and a spray cooling mechanism inside the machine tool. The spray cooling mechanism includes a water tank, which is fixedly connected to the right side of the machine tool. A spray pipe is installed inside the water tank via a water pump, and a nozzle is provided at the bottom of the spray pipe. The water pump delivers coolant from the water tank to the spray pipe and nozzle, enabling direct and uniform spray cooling of key structural components inside the machine tool, quickly removing heat generated during processing, and effectively preventing overheating due to prolonged operation. A planar linkage mechanism composed of a first rotating rod and a connecting rod group converts the rotational motion into the reciprocating oscillation of a second rotating rod and a disturbance plate fixed thereon. This oscillation effectively breaks the static distribution of air and cooling droplets inside the machine tool.

[0007] Preferably, a motor is fixedly connected to the side of the machine tool, and a first rotating rod is fixedly connected to the output end of the motor via a coupling. A first connecting rod is fixedly connected to the right side of the first rotating rod, and a second connecting rod is rotatably connected to the right side of the first connecting rod.

[0008] Preferably, the machine tool has a second rotating rod internally connected to it. This second rotating rod movably passes through the machine tool and extends to its right side. A disturbance plate is fixedly connected to the outer wall of the second rotating rod. The fan, in addition to spray cooling, provides forced air convection, accelerating airflow and evaporative heat dissipation within the machine tool, further reducing the ambient temperature. Through the engagement of a push plate fixed on the second rotating rod and a fixed frame on the fan's horizontal plate, the rotational motion of the second rotating rod is converted into the horizontal reciprocating linear motion of the fan assembly. This allows the fan to periodically sweep a larger area, avoiding overheating in localized dead zones and achieving dynamic and uniform auxiliary cooling.

[0009] Preferably, a third connecting rod is fixedly connected to the right side of the second rotating rod. The second and third connecting rods are rotatably connected. When the internal temperature of the machine tool rises, the control system starts the water pump. The water pump pumps the coolant in the water tank into the spray pipe, and finally sprays it out in the form of mist through the nozzle, directly covering the key heat-generating structural components inside the machine tool, achieving initial cooling through evaporative heat absorption. To improve cooling uniformity, the cooling system simultaneously starts the motor. The motor drives the first rotating rod to rotate, and through the linkage mechanism composed of the first and second connecting rods, the rotational motion is converted into reciprocating oscillation. This oscillation is transmitted to the second rotating rod through the third connecting rod, causing the disturbance plate fixed on the second rotating rod to oscillate reciprocally within the internal space of the machine tool. The oscillation of the disturbance plate strongly agitates the air inside the machine tool, generating turbulence. This ensures that the cooling mist droplets sprayed from the nozzle are evenly dispersed, avoiding localized over-wetting or cooling dead zones. It accelerates the mixing of hot and cold air, and cooling mist droplets with hot surfaces, significantly improving heat exchange efficiency, thereby achieving rapid and uniform heat dissipation and preventing thermal deformation of parts.

[0010] Preferably, the machine tool is provided with a fan cooling mechanism inside, the fan cooling mechanism includes a first slide groove, the first slide groove is opened inside the machine tool, and a first slider is slidably connected inside the first slide groove.

[0011] Preferably, a horizontal plate is fixedly connected to the side of the first slider, a fan is fixedly connected to the bottom of the horizontal plate, and a fixed frame is fixedly connected to the top of the horizontal plate. A push plate is fixedly connected to the outer wall of the second rotating rod, and the fixed frame is sleeved on the outside of the push plate. When the second rotating rod rotates, the push plate fixed to its outer wall moves in a circular motion. Since the push plate is sleeved inside the fixed frame, the circular motion of the push plate periodically pushes the fixed frame, thereby converting the circular motion into a horizontal reciprocating linear motion of the fixed frame, the connected horizontal plate, and the fan along the first slide groove. During the reciprocating motion, the fan continuously blows air into the machine tool. This sweeping air supply can cover a wider area, further enhance air circulation, assist in evaporative heat dissipation, and combine with the airflow generated by the disturbance plate to form a more effective forced convection circulation inside the machine tool, ensuring that heat is continuously and efficiently removed.

[0012] Preferably, a shock-absorbing mechanism is provided between the base and the housing. The shock-absorbing mechanism includes a fixing plate, which is fixedly connected to the side of the housing. A damping rod is fixedly connected to the top of the fixing plate. A spring is sleeved on the outer wall of the damping rod, and the damping rod is fixedly connected to the bottom of the base.

[0013] Preferably, the top of the housing is provided with a second slide groove, and a second slider is slidably connected inside the second slide groove. A support rod is hinged between the second slider and the base. Through the elastic damping system composed of the damping rod and the spring, the vibration and impact energy generated during machine tool processing can be effectively absorbed, reducing the vibration transmitted to the base and housing, ensuring the smooth operation and processing accuracy of the machine tool itself. Through the hinged sliding mechanism composed of the support rod, the second slider and the second slide groove, while providing vertical damping, the horizontal displacement and overturning tendency of the base are limited, ensuring the overall structural stability and safety of the machine tool under dynamic loads.

[0014] Preferably, a square frame is fixedly connected to the top of the housing, and two air bladders are arranged inside the square frame. The two air bladders are in contact with each other, and the vibration generated by the machine tool is transmitted downward through the base. The damping system composed of a damping rod and a spring responds immediately: the spring absorbs and buffers most of the vertical impact energy. The damping medium inside the damping rod generates frictional resistance through relative motion, converting vibration energy into heat energy for dissipation, effectively suppressing the reciprocating oscillation of the spring, and causing the vibration to decay rapidly. During the damping process, the support rod hinged to the base pushes the second slider to slide in the second slide groove. This structure allows the base to move vertically, but restricts its horizontal displacement and tilt, ensuring the stability of the machine tool. When encountering a large impact, the downward pressure of the base may compress the two air bladders arranged inside the square frame. The air bladders provide additional flexible buffering through their own compression deformation, preventing rigid collisions and protecting the machine tool and housing structure.

[0015] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This CNC machine tool with cooling for machine tool structural components uses a water pump to deliver coolant from a water tank to spray pipes and nozzles, enabling direct and uniform spray cooling of key internal structural components. This quickly removes heat generated during machining, effectively preventing overheating caused by prolonged operation. A planar linkage mechanism consisting of a first rotating rod and a connecting rod assembly converts rotational motion into the reciprocating oscillation of a second rotating rod and a disturbance plate fixed thereon. This oscillating motion effectively breaks the static distribution of air and cooling droplets inside the machine tool.

[0016] 2. This CNC machine tool with cooling for its structural components utilizes a fan that, in addition to spray cooling, provides forced air convection to accelerate airflow and evaporative heat dissipation within the machine tool, further reducing the ambient temperature. The rotational motion of the second rotating rod is converted into horizontal reciprocating linear motion of the fan assembly through the engagement of a push plate fixed on the second rotating rod and a fixed frame on the fan's horizontal plate. This allows the fan to periodically sweep air over a larger area, preventing overheating in localized dead zones and achieving dynamic and uniform auxiliary cooling.

[0017] 3. This CNC machine tool with cooling for machine tool structural components effectively absorbs the vibration and impact energy generated during machine tool processing through an elastic damping system composed of damping rods and springs, reducing the vibration transmitted to the base and housing, ensuring the smooth operation and machining accuracy of the machine tool itself. Through the hinged sliding mechanism composed of support rods, second sliders and second slides, it provides vertical vibration damping while limiting the horizontal displacement and overturning tendency of the base, ensuring the overall structural stability and safety of the machine tool under dynamic loads.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-7One embodiment of the present invention is as follows: A CNC machine tool with cooling for machine tool structural components includes a base 1, a machine tool 2 fixedly connected to the top of the base 1, a housing 3 provided at the bottom of the base 1, a spray cooling mechanism 4 provided inside the machine tool 2, the spray cooling mechanism 4 including a water tank 411, the water tank 411 fixedly connected to the right side of the machine tool 2, a spray pipe 412 provided inside the water tank 411 via a water pump, a nozzle 413 provided at the bottom of the spray pipe 412, a motor 414 fixedly connected to the side of the machine tool 2, and the output end of the motor 414 being fixed via a coupling. A first rotating rod 415 is fixedly connected to the machine tool 2. A first connecting rod 416 is fixedly connected to the right side of the first rotating rod 415. A second connecting rod 417 is rotatably connected to the right side of the first connecting rod 416. A second rotating rod 418 is rotatably connected inside the machine tool 2, and the second rotating rod 418 movably passes through the machine tool 2 and extends to its right side. A disturbance plate 419 is fixedly connected to the outer wall of the second rotating rod 418. A third connecting rod 420 is fixedly connected to the right side of the second rotating rod 418. The second connecting rod 417 and the third connecting rod 420 are rotatably connected. When the internal temperature of the machine tool 2 rises, the control system starts the water pump. The water pump pumps the coolant in the water tank 411 into the spray pipe 412, and finally sprays it out in the form of mist through the nozzle 413, directly covering the key heat-generating structural components inside the machine tool 2, and performing preliminary cooling through evaporative heat absorption. To improve the cooling uniformity, the cooling system simultaneously starts the motor 414. Motor 414 drives the first rotating rod 415 to rotate, and the rotational motion is converted into reciprocating oscillation through the linkage mechanism composed of the first connecting rod 416 and the second connecting rod 417. This oscillation is transmitted to the second rotating rod 418 through the third connecting rod 420, causing the disturbance plate 419 fixed on the second rotating rod 418 to oscillate reciprocally within the internal space of the machine tool 2. The oscillation of the disturbance plate 419 strongly agitates the air inside the machine tool 2, generating turbulence. This ensures that the cooling droplets sprayed from the nozzle 413 are evenly dispersed, avoiding localized over-wetting or cooling dead zones. It accelerates the mixing of hot and cold air, and cooling droplets and hot surfaces, significantly improving heat exchange efficiency, thereby achieving rapid and uniform heat dissipation and preventing thermal deformation of parts.

[0023] Please see Figure 1-7 Based on the above embodiments, in another embodiment of the present invention, a fan cooling mechanism 5 is provided inside the machine tool 2. The fan cooling mechanism 5 includes a first slide groove 511, which is opened inside the machine tool 2. A first slider 512 is slidably connected inside the first slide groove 511. A horizontal plate 513 is fixedly connected to the side of the first slider 512. A fan 514 is fixedly connected to the bottom of the horizontal plate 513. A fixed frame 515 is fixedly connected to the top of the horizontal plate 513. A push plate 516 is fixedly connected to the outer wall of the second rotating rod 418. The fixed frame 515 is sleeved on the outside of the push plate 516. When the second rotating rod 418 rotates, the push plate 516 fixed to its outer wall moves in a circular motion. Since the push plate 516 is fitted inside the fixed frame 515, the circular motion of the push plate 516 periodically pushes the fixed frame 515, thereby converting the circular motion into horizontal reciprocating linear motion of the fixed frame 515, the connected horizontal plate 513, and the fan 514 along the first slide groove 511. During the reciprocating motion, the fan 514 continuously blows air into the machine tool 2. This sweeping airflow can cover a wider area, further enhancing air circulation and assisting in evaporative heat dissipation. Combined with the airflow generated by the disturbance plate 419, it forms a more effective forced convection circulation inside the machine tool 2, ensuring that heat is continuously and efficiently removed.

A support rod 616 is hinged between the second slider 615 and the base 1. A square frame 617 is fixedly connected to the top of the housing 3. An airbag 618 is provided inside the square frame 617. There are two square frames 617 and two airbags 618. The two airbags 618 are in contact with each other. The vibration generated by the machine tool 2 is transmitted downward through the base 1. The shock-absorbing system composed of the damping rod 612 and the spring 613 responds immediately: the spring 613 absorbs and buffers most of the vertical impact energy. The damping medium inside the damping rod 612 generates frictional resistance through relative motion, converting vibration energy into heat energy for dissipation. This effectively suppresses the reciprocating oscillation of the spring 613, causing the vibration to decay rapidly. During the damping process, the support rod 616, hinged to the base 1, pushes the second slider 615 to slide within the second groove 614. This structure allows the base 1 to move vertically but constrains its horizontal displacement and tilt, ensuring the stability of the machine tool 2. When encountering a large impact, the downward pressure of the base 1 may compress the two airbags 618 set within the square frame 617. The airbags 618 provide additional flexible cushioning through their own compression deformation, preventing rigid collisions and protecting the structure of the machine tool 2 and the housing 3.
