Description

Technical Field

[0001] This utility model belongs to the field of milling machine heat dissipation technology, specifically relating to a heat dissipation device for CNC milling machines. Background Technology

[0002] A CNC milling machine is an automated machine tool equipped with a program control system. It can automatically mill workpieces according to pre-programmed instructions. Its basic principle is to convert digital machining instructions into the movement of the machine tool's axes and the rotation of the spindle through the CNC system. This allows for precise control of the tool's position and trajectory relative to the workpiece, enabling milling of workpieces of various shapes. The CNC system decomposes the three-dimensional model data of the part into a series of tiny straight line segments and arc segments, and then controls the machine tool's axes and spindle to move in a certain sequence and speed, causing the tool to cut along these line segments and arc segments, ultimately producing a part that meets the requirements. During the milling process, the spindle system, feed system, and electrical control cabinet of the milling machine are all heat sources. When dissipating heat in these areas, the installation location and size of the heat dissipation device are limited, which can interfere with the components inside the milling machine and limit its application range.

One end of one connecting frame 1 is connected to an adjusting frame 2, and heat-conducting plates 3 are rotatably connected to both sides of the connecting frame 1. An mounting frame 4 is installed at one end of the adjusting frame 2, a cooling fan 31 is installed on one side of the heat-conducting plate 3, and several cooling fins 32 are provided on the other side of the heat-conducting plate 3. A through groove 33 is provided on one side of the heat-conducting plate 3, and an installation assembly is provided between the adjusting frame 2 and the mounting frame 4.

[0021] In this embodiment: The main support frame of this novel device is formed by several connecting frames 1 and gooseneck rods 11. Wiring grooves 12 are provided inside the connecting frames 1 and gooseneck rods 11, and these grooves are interconnected. Wiring grooves 12 are used to route and wire electrical components. One end of each connecting frame 1 is connected to an adjusting frame 2. The shape and rotation angle of this novel device can be adjusted by the adjusting frame 2, increasing its installation range and thus its usability on the milling machine. Heat-conducting plates 3 are rotatably connected to both sides of the connecting frame 1. A mounting bracket 4 is installed at one end of the adjusting bracket 2 to facilitate installation on the milling machine. A cooling fan 31 is installed on one side of the heat-conducting plate 3, and several cooling fins 32 are provided on the other side. A through groove 33 is provided on one side of the heat-conducting plate 3. The mounting bracket 4, cooling fan 31, cooling fins 32, and through groove 33 form a heat dissipation unit. When this device is installed in a high-heat area on the milling machine, the heat-conducting plate 3 and cooling fins 32 can absorb heat from the air in that area, thus conducting heat... The through slot 33 on plate 3 connects to the inner cavity of the outer protective shell of the cooling fan 31. When the cooling fan 31 blows air to dissipate heat, it accelerates the airflow on both sides of the heat conduction plate 3 and also accelerates the airflow around the heat dissipation fins 32, driving heat out of the milling machine. Several heat dissipation units dissipate heat in the heat accumulation area inside the milling machine. An installation component is provided between the adjustment frame 2 and the mounting frame 4. Through the installation component, one end of the adjustment frame 2 can rotate on the top of the mounting frame 4 for easy adjustment. In use, the mounting frame 4 is installed on the milling machine. The overall shape of the present invention is adjusted by several connecting frames 1 and gooseneck rods 11 so that it bypasses the components inside the milling machine and surrounds the high-heat components or is close to the high-heat area. The overall angle of the connecting frame 1 and the components above it is adjusted by the adjustment frame 2 so that the present invention is small in size, can be bent and deformed, and is suitable for different heat-generating positions on the milling machine. In use, the overall shape can be adjusted according to the installation position, so that it can be used in multiple positions, with high flexibility and easy operation.

[0022] The adjustment frame 2 includes several universal joints 21 and limiting telescopic frames 22. The several universal joints 21 and limiting telescopic frames 22 are arranged alternately, and the several limiting telescopic frames 22 are rotatably connected through several universal joints 21. By setting several universal joints 21 and limiting telescopic frames 22 to form an integral adjustment frame 2, the angle is adjusted through the universal joints 21, and the overall length of the adjustment frame 2 is adjusted through the universal joints 21.

[0023] The mounting assembly includes an annular connecting frame 211 disposed on one side of one of the universal joints 21. The top of the mounting frame 4 has a connecting groove 41 that matches the annular connecting frame 211. A fixing pin 42 is detachably connected between the annular connecting frame 211 and the mounting frame 4. By setting the annular connecting frame 211 and the connecting groove 41, the annular connecting frame 211 is rotatably connected inside the connecting groove 41, which allows the adjustment frame 2 to be rotated, further increasing its installation flexibility.

[0024] The top of the mounting bracket 4 and the top of the annular connecting bracket 211 are provided with several limiting holes 43, and the diameter of the fixing pin 42 matches the diameter of the limiting holes 43. By setting several limiting holes 43, the position of the annular connecting bracket 211 can be limited by the fixing pin 42. After rotating the annular connecting bracket 211 to adjust the angle, it is limited.

[0025] The through groove 33 is connected to the outer shell of the cooling fan 31 on one side. The width of the through groove 33 is less than the length of the heat dissipation fins 32. The heat dissipation fins 32 are fixedly connected to one side of the heat conduction plate 3. The through groove 33 on the heat conduction plate 3 is connected to the inner cavity of the outer protective shell of the cooling fan 31. When the cooling fan 31 blows air to dissipate heat, it accelerates the air flow on both sides of the heat conduction plate 3 and can also accelerate the air flow around the heat dissipation fins 32.

[0026] Several heat dissipation fins 32 are arranged at equal intervals, and all of the heat dissipation fins 32 are inclined; the presence of several heat dissipation fins 32 increases the contact area with air, thereby increasing the heat dissipation effect.

[0027] A rotating joint 34 is provided at one end of the heat-conducting plate 3, and the heat-conducting plate 3 is rotatably connected to the connecting frame 1 through the rotating joint 34; by providing the rotating joint 34, it is easy to adjust the angle of the heat-conducting plate 3, and during installation, it can make way for the various parts on the milling machine.

[0028] The working principle and usage process of this utility model are as follows: In use, the device is installed on a suitable position on a milling machine using the mounting bracket 4. By setting several connecting brackets 1 and gooseneck rods 11, the overall shape of the device is adjusted to allow it to bypass the internal components of the milling machine and surround or approach areas with high heat. The shape and rotation angle of the device are adjusted using the adjusting bracket 2 to increase its installation range and thus its usability within the milling machine. A through groove 33 is provided on one side of the heat-conducting plate 3. The mounting bracket 4, cooling fan 31, cooling fins 32, and through groove 33 are all connected. When this device is installed in a high-heat area of ​​a milling machine, the heat-conducting plate 3 and the heat dissipation fins 32 can absorb heat from the air in that area. The through groove 33 on the heat-conducting plate 3 connects to the inner cavity of the outer protective shell of the heat dissipation fan 31. When the heat dissipation fan 31 blows air to dissipate heat, it accelerates the airflow on both sides of the heat-conducting plate 3 and also accelerates the airflow around the heat dissipation fins 32, driving the heat out of the milling machine. Several heat dissipation units can dissipate heat from the heat-accumulating areas inside the milling machine. Multiple units of this device can be installed on the same equipment as needed to perform targeted heat dissipation and improve the heat dissipation effect.
