Detailed Implementation

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope. Example

[0018] Please see Figures 1-4This utility model discloses a cooling device for CNC machine tools, comprising an L-shaped fixed frame 1 and an arc-shaped spray pipe 5. The left end of the L-shaped fixed frame 1 has two sets of elongated holes 2. An L-shaped support arm 3 is slidably mounted on the right side of the L-shaped fixed frame 1, and a rectangular tube 4 is slidably fitted onto the L-shaped support arm 3. The arc-shaped spray pipe 5 is installed at the bottom of the rectangular tube 4. A pipe interface 6 is fixedly connected to the middle of the right end of the arc-shaped spray pipe 5 for connection to the machine tool's cooling pipeline. Multiple sets of nozzle interfaces 7 are fixedly connected annularly at equal intervals on the inner wall of the arc-shaped spray pipe 5, and nozzles 8 are threadedly connected to each set of nozzle interfaces 7. In use, the L-shaped fixed frame 1 can be fixedly installed on the side wall of the CNC machine tool with the spindle inside by bolts engaging with the elongated holes 2. Located above the spindle, the pipe interface 6 is connected to the coolant pipeline in the CNC machine tool via an external pipeline, thereby connecting the arc-shaped spray pipe 5 to the cooling system of the CNC machine tool. This allows the CNC machine tool to deliver cutting fluid into the arc-shaped spray pipe 5. By sliding the L-shaped support arm 3 to the right, the rectangular pipe 4 and the arc-shaped spray pipe 5 can cross the spindle. By sliding the position of the rectangular pipe 4, the height of the arc-shaped spray pipe 5 can be adjusted, ensuring that the arc-shaped spray pipe 5 is positioned around the tool before machining. This ensures that the multiple sets of nozzles 8 distributed in a ring on the inner side of the arc-shaped spray pipe 5 all point towards the tool. During cutting, the nozzles 8 can spray cutting fluid onto the tool in a ring, enhancing the cooling effect and improving practicality.

[0019] The L-shaped support arm 3 has threaded guide posts 9 fixedly connected to the lower left and right ends of its top. Both sets of threaded guide posts 9 are fitted with wing nuts 10. A storage groove is provided extending to the left from the right end of the L-shaped fixing frame 1. A horizontal slot 11 is provided at the top of the L-shaped fixing frame 1, communicating with the storage groove. The L-shaped support arm 3 is slidably installed in the storage groove through the cooperation of the top threaded guide post 9 and the horizontal slot 11. A vertical slot 12 is provided at the right end of the rectangular tube 4. The rectangular tube 4 slides through the vertical slot 12 in cooperation with the right threaded guide post 9 of the L-shaped support arm 3. Mounted on the L-shaped support arm 3, two sets of vertical slots 12 are respectively pressed against the top of the L-shaped fixing frame 1 and the right end of the rectangular tube 4. When adjusting the position of the L-shaped support arm 3 and the rectangular tube 4, the adjustment can be made by loosening the wing nut 10. The adjustment of the L-shaped support arm 3 can be limited by the cooperation of the threaded guide post 9 and the horizontal slot 11, preventing the L-shaped support arm 3 from detaching from the L-shaped fixing frame 1. The adjustment of the rectangular tube 4 can also be limited by the cooperation of the vertical slot 12 and the threaded guide post 9, preventing the rectangular tube 4 from detaching from the L-shaped support arm 3.

[0020] Two sets of ear plates 13 are symmetrically fixedly connected to the top outer wall of the arc-shaped spray pipe 5. Two sets of wing bolts 14 are screwed onto each set of ear plates 13. Two sets of screw holes 15 are opened on the lower side of both ends of the rectangular tube 4. The two sets of ear plates 13 are installed at the bottom ends of the rectangular tube 4 through the cooperation of the wing bolts 14 and the screw holes 15. The cooperation between the ear plates 13 and the rectangular tube 4 prevents the arc-shaped spray pipe 5 from shaking back and forth during installation. The ear plates 13 are installed by two sets of wing bolts 14, which can effectively prevent the arc-shaped spray pipe 5 from rotating, thereby improving the firmness of the installation of the arc-shaped spray pipe 5.

[0021] The left end of the L-shaped fixing bracket 1 is fixedly connected with a fastening rubber pad 16; by setting the fastening rubber pad 16, the L-shaped fixing bracket 1 can be installed more tightly and securely.

[0022] Both sets of wing nuts 10 are fixedly connected to the bottom end with anti-loosening washers 17; by setting anti-loosening washers 17, the wing nuts 10 can be tightened more securely, avoiding loosening and slippage.

[0023] This utility model discloses a cooling device for CNC machine tools. In operation, an L-shaped mounting bracket 1 is fixedly installed on the side wall of the CNC machine tool, above the spindle, using bolts and elongated holes 2. An external pipeline connects the pipe interface 6 to the coolant pipeline in the CNC machine tool, thereby connecting the arc-shaped spray pipe 5 to the machine tool's cooling system. This allows the CNC machine tool to deliver cutting fluid into the arc-shaped spray pipe 5. The L-shaped support arm 3 is adjusted by sliding it to the right. Positioning the rectangular tube 4 and the arc-shaped spray nozzle 5 so that they span the spindle, the height of the arc-shaped spray nozzle 5 can be adjusted by sliding the position of the rectangular tube 4, so that the arc-shaped spray nozzle 5 is positioned around the tool before the tool is processed, and thus the multiple sets of nozzles 8 distributed in a ring on the inner side of the arc-shaped spray nozzle 5 all point towards the tool. After adjustment, the wing nut 10 needs to be tightened to fix the position of the L-shaped support arm 3 and the rectangular tube 4. During the cutting process, the cutting fluid can be sprayed in a ring through the nozzles 8 to fully cool the tool.

[0024] The cooling device for CNC machine tools of this utility model has common mechanical installation, connection or setting methods, and can be implemented as long as it can achieve its beneficial effect. The wing nut 10 and wing bolt 14 of the cooling device for CNC machine tools of this utility model are purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
