[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model is equipped with a cooling circulation mechanism to cool down the drilling shaft and improve the drilling efficiency of the drilling shaft. The drilling shaft is used to drill parts during drilling. The long-term operation of the drilling shaft will cause the temperature of the drilling shaft to be too high and affect the working quality of the drilling shaft. Therefore, it is necessary to cool down the drilling shaft. First, the solenoid valve works so that the solenoid valve does not seal the liquid adding tank. Then, coolant is added through the liquid adding tank. The motor works to drive the anti-precipitation shaft and the cylinder body drives the scraper plate to move to merge the precipitation of the long-term coolant. The hydraulic rod works to drive the drilling shaft to move so that the first position sensor and the second position sensor are in a horizontal straight line and send a signal.

The cooling nozzle is used to cool the drilling shaft. The electric push rod works to drive the water collecting tank to move. The water collecting tank collects the sprayed coolant. Then, the drilling shaft is cooled to avoid the situation where the drilling shaft works for a long time and causes the temperature of the drilling shaft to be too high and affects the work.

[0017] 2. The utility model is equipped with a cleaning mechanism to clean the dust generated by drilling. A large amount of dust is generated during drilling, but the existing CNC machine tools do not have the function of removing dust, which results in manual cleaning, which is very inconvenient and increases the labor intensity of workers. Therefore, it is necessary to adsorb and clean the dust generated during drilling. First, the telescopic adjustable pipeline is pulled so that one end of the telescopic adjustable pipeline is close to the position of the drill hole, and the ventilation pipe allows air to circulate inside the cleaning box. Then the vacuum cleaner works to adsorb the dust into the protective dust suction net through the telescopic adjustable pipeline. At the same time, the telescopic adjustable pipeline can be removed from the first mounting ring through the second mounting ring for disassembly, which is convenient for processing the dust adsorbed in the cleaning box. The dust generated during drilling is cleaned, thereby improving the versatility of the CNC machine tool. BRIEF DESCRIPTION OF THE DRAWINGS
