[0023] Embodiment 1

[0024] Please refer to Figures 1 to 4 As shown, a CNC machine tool structure with a cooling effect includes a support plate 1, and support legs 9 are fixedly connected at the four corners of the lower end surface of the support plate 1 to effectively ensure the stability of the support plate 1, and side panels 2 are fixedly connected to the left and right sides of the upper end surface of the support plate 1, and a fixing frame 3 is fixedly connected to the middle of the opposite surfaces of the left and right side panels 2, and the fixing frame 3 is in the shape of a groove with an opening downward, so as to ensure the stability of the left and right side panels 2, and a processing platform 4 is fixedly connected to the upper part of the opposite surfaces of the left and right side panels 2, and an organism 6 is fixedly connected to the middle of the rear side of the upper end surface of the support plate 1, and the processing device on the organism 6 is located above the processing platform 4.

[0025] In order to quickly cool down the processing platform 4 and the clamping device, cooling boxes 7 are fixedly connected to the upper parts of the opposite surfaces of the left and right side panels 2, a cold water pipe 8 is arranged through the front of the left cooling box 7, and the end of the cold water pipe 8 extends to the front side of the right cooling box 7, and the head end and the end of the cold water pipe 8 are connected to an external cooling water source for convenient cooling, so that the cooled cooling box 7 contacts the side panel 2 and the processing platform 4, ensuring that the temperature can be conducted to reduce the temperature of the processing platform 4 and the clamping device.

[0026] In order to ensure cooling of the lower part of the processing platform 4, an air cooling device is provided on the upper end surface of the fixed frame 3;

[0027] In order to ensure the cooling of the lower end surface of the processing platform 4, and thus cool the upper clamping device through heat conduction, an air cooling device is composed of a drive motor 10, a cross 11, a rotating shaft 12, a first fan blade 13 and an auxiliary cooling device. The drive motor 10 is fixedly connected to the center of the lower end surface of the horizontal plate of the fixed frame 3, and the motor shaft of the drive motor 10 extends through and extends to the upper end surface of the fixed frame 3 and is fixedly connected to the cross 11, and the rotating shaft 12 is fixedly connected to the middle of the upper end surface of the cross 11, and the first fan blade 13 is fixedly connected to the upper end surface of the rotating shaft 12, and the auxiliary cooling device is fixedly connected to the end of the upper end surface of the cross 11.

[0028] In order to better reduce the temperature of the processing environment, an auxiliary cooling device is formed by opening 14, sleeve 15, connecting rod 16, micro motor 17 and second fan blade 18. An opening 14 is opened at the end of the end face of the cross 11, and a sleeve 15 is fixedly connected to the end of the upper end face of the cross 11, and the sleeve 15 is located outside the opening 14. A connecting rod 16 is fixedly connected to the middle of the inner wall of the inner cavity of the sleeve 15, and the end of the connecting rod 16 is fixedly connected to the outer wall of the micro motor 17. The second fan blade 18 is fixedly connected to the end of the motor shaft of the micro motor 17, and the length of the second fan blade 18 is less than the radius of the sleeve 15.

[0029] In order to ensure that the temperature of the cooling box 7 drops rapidly, the cold water pipe 8 is located in a section of the inner cavity of the left and right cooling boxes 7 and has a continuous S-shaped structure, and the inner wall of the inner cavity of the cold water pipe 8 is evenly and fixedly connected with semicircular protrusions to slow down the water flow rate. The water inside the cold water pipe 8 with the continuous S-shaped structure stays in the cooling box 7 for a longer time, ensuring that the cold water box 7 cools rapidly.

[0030] In order to ensure the stability of the processing platform 4, a cushion block is fixedly connected to the lower end surface of the supporting leg 9, and a rubber pad is fixedly connected to the lower end surface of the cushion block, which effectively prevents the machine tool from being displaced.

[0031] In order to further reduce the temperature of the processing platform 4, heat sinks 5 are evenly and fixedly connected to the lower end surface of the processing platform 4, and the heat sinks 5 are arranged in a linear array on the lower end surface of the processing platform 4 to accelerate the cooling speed.

[0032] Working principle: When in use, the cooling of machine tool structural parts such as the bed, columns, and beams is heated by the internal motor. The head and tail ends of the cold water pipe 8 are fixedly connected to the cooling water source by a water pipe to ensure that cold water flows through the cold water pipe 8 inside the cooling box 7 to reduce the temperature of the cooling box 7. The cooling box 7 can quickly reduce the temperature of the clamping device. An external power supply is used to start the drive motor 10. The drive motor 10 drives the cross 11 and the rotating shaft 12 to rotate. The rotating shaft 12 drives the first fan blade 13 to rotate to ensure that the processing platform 4 is quickly cooled. The micro motor 17 is powered by a battery and started. The micro motor 17 drives the second fan blade 18 to rotate. The four groups of auxiliary cooling devices on the cross 11 rotate, and the wind blown by the second fan blade 18 can quickly cool down the machine tool processing environment to ensure a low temperature in the processing environment, thereby ensuring that the machine tool temperature is reduced.
