[0002] Deep hole machining CNC tool is a kind of cutting tool specially used for machining deep holes. It controls the tool to cut on the material through the CNC system to achieve precise machining requirements. Deep hole machining CNC tool usually consists of tool bar, tool head and blade. The tool bar is fixed on the CNC machine tool, and the tool head is connected to the tool bar and is responsible for transmitting the cutting force to the blade. The blade is the part that actually cuts. Its shape and tool angle will be designed according to different machining requirements. The CNC system controls the tool feed speed, rotation speed and cutting depth and other parameters through a preset program, so as to achieve precise deep hole machining. Deep hole machining CNC tool has the characteristics of high efficiency, precision and stability, and is widely used in automobile manufacturing, aerospace and mold manufacturing and other fields.

[0003] During the use of deep hole processing CNC tools, it is necessary to spray coolant on their surface for cooling. Although the existing technology has met the user's needs to a certain extent, there are still certain defects in the use process. The specific problems are as follows: the existing coolant spraying methods are mostly manual spraying or fixing the nozzle on one side of the inside of the box to spray the entire box over a large area. The former is time-consuming and labor-intensive during operation, and has low safety and may cause harm to the operator. The latter has low spraying accuracy and cannot accurately spray and cool the tool and the processing position, which reduces the cooling efficiency and causes a certain degree of waste of coolant.

[0004] In order to solve the above problems, we have made improvements and proposed a cooling device for CNC tools for deep hole processing. Utility Model Content

[0022] Through the above technical scheme, the suction force generated by the liquid pump 6 sucks the coolant and transmits it to the nozzle 10 through the transmission pipe 4, the first bellows 7, the second bellows 8 and the cross pipe 9. The nozzle 10 sprays the coolant, which can spray and cool the tool body 15 and the workpiece. In the process of the adjustment mechanism 11 adjusting the motor box 12 and the tool body 15 to move, the motor box 12 drives the second bellows 8 to move through the connecting rod 13.
