The bottom end of the connecting block is The boring tool is fixedly connected, and atomizing nozzles are provided on both sides of the boring tool. The beneficial effects achieved by the utility model are: by setting the support ring and the atomizing nozzle, the cutting area and the boring tool can be cooled, thereby To improve the cutting accuracy and maintain good tolerance dimensions, by setting the blade and boring tool, when the boring tool edge is seriously worn and needs to be replaced, unscrew the connecting wire and remove the protective shell, and then remove the two hexagonal screws After being taken out from the threaded hole, the connecting block can be pulled out from the slot, and the boring tool can be directly removed for replacement without the need for overall replacement, and the replacement operation is simple.

However, this patented technology still has the following flaws: First, there is no shielding structure on the outside of the nozzle, which causes the boring tool to rotate at high speed during the actual spraying process, causing the cutting fluid and debris generated during the cutting process to splash, causing CNC The inside of the milling and boring machine equipment is dirty and messy, which makes cleaning more difficult. In addition, the height of the nozzle is not adjustable, so its spray point and spray range are fixed, resulting in poor overall cooling effect of the boring tool.

Utility model content

Based on the above technical problems, the present utility model provides a tool cooling device for a CNC gantry milling and boring machine that prevents major accidents.

The utility model provides a tool cooling device for a CNC gantry milling and boring machine, which is characterized by including a tool, a tool holder, a bearing, a support column, a connecting plate, a baffle, a liquid inlet pipe, a protective cover, a telescopic hose, a nozzle, Boring cutter, clamping fixed ring, telescopic cylinder and fixing piece, the cutter is connected to the tool holder through a bearing, the inside of the bottom of the cutter is connected to the boring cutter through the fixing piece, and the outside of the bottom of the cutter is connected to the fixing piece and the protective cover, The tool holder is connected to a connecting plate through a support column, and the connecting plate is connected to a shield around it. Telescopic cylinders are provided on both sides of the boring tool, and the telescopic end of the telescopic cylinder is connected to a clamping fixed ring. The inside of the retaining ring is connected to the nozzle, the top of the nozzle is connected to the telescopic hose, and the telescopic hose is connected to the liquid inlet pipe.

A groove is provided at the bottom of the tool, and through holes are provided on the left and right sides of the tool holder and the connecting plate, and a liquid inlet pipe is connected in the through hole.

The beneficial effects of the utility model are as follows: The utility model is a tool cooling device for a CNC gantry milling and boring machine. By providing a baffle, the baffle can prevent the sprayed cutting fluid and debris from spreading and splashing at will, so that the splash range can be reduced Shrink, the splashed cutting fluid mixed with debris adheres to the inner wall of the shield, and then slowly flows out, preventing any splashed cutting fluid and debris from causing the entire milling and boring machine to be too dirty, and debris from randomly splashing into the parts of the milling and boring machine that are difficult to clean; By setting up a telescopic cylinder, the telescopic cylinder drives the nozzle to move up and down through the clamping fixed ring, so that the spray range of the nozzle changes, further adapting to the processing cooling needs of different workpieces. For example, if the processed workpiece is too large and the cooling area increases, the telescopic cylinder can be activated , spray the heating part back and forth to cool down. If the workpiece is small and the heating part is concentrated, you can not start the telescopic cylinder and only spray one part to get a better cooling effect.
