[0031] The chamfering mechanism 2 is fixed on the top surface of the worktable 11 and includes a chamfering support 21, a chamfering spindle 22, a chamfering drill bit 23, and a drive motor 24. The chamfering support 21 is fixed on the top surface of the worktable 11. A spindle housing is connected to one side of the chamfering support 21. The chamfering spindle 22 is connected to the inside of the chamfering support 21 by a bearing. The other end of the chamfering spindle is located inside the spindle housing. The chamfering drill bit 23 is fixed at the end of the chamfering spindle 22 away from the chamfering support 21. The drive motor 24 is located above the spindle housing. A transmission mechanism is connected between the end of the chamfering spindle 22 away from the chamfering drill bit 23 and the drive motor 24. The transmission mechanism 25 can be a gear and rack drive, a belt drive, or a chain drive, etc.

[0032] The cooling assembly 3 is fixed on the side of the chamfering support 21 near the chamfering drill bit 23 and located below the chamfering spindle 22. It includes a cooling nozzle 31, an air tank 32 and an air pump 33. A first connecting block 4 is provided between the cooling nozzle 31 and the chamfering support 21. The cooling nozzle 31 is fixed on the side of the first connecting block 4 away from the chamfering support 21. The air tank 32 is located inside the first connecting block 4 and is connected to the cooling nozzle 31. The air pump 33 is fixed on the side of the chamfering support 21 and is connected to the air tank 32 through a pipe. The air pump 33 is also connected to an external air source.

[0033] Gas is delivered to the gas tank 32 by the air pump 33 and stored therein. When the chamfering drill bit 23 is operating, the cooling nozzle 31 sprays the cooling gas from the gas tank 32 onto the processing area, effectively cooling the tool and flange workpiece and preventing damage and precision loss caused by high temperature.

[0034] Reference Figure 4 and Figure 5 As shown, the cooling nozzle 31 has several needle-type nozzles 31A inside. The needle-type nozzles 31A are evenly arranged in a grid pattern, and each needle-type nozzle 31A is connected to the air tank 32, which further ensures the uniformity of the cooling effect.

[0035] Specific reference Figure 3 , Figure 5 and Figure 7 An adjustment component 5 is provided between the first connecting block 4 and the chamfered support 21. A second connecting block 6 is fixed between the adjustment component 5 and the chamfered support 21. The adjustment component 5 includes an adjustment rod 51 and a drive cylinder 52. One end of the adjustment rod 51 is hinged to the side of the first connecting block 4 away from the cooling nozzle 31.

A push block 41 is fixed around the first connecting block 4. The output end of the drive rod of the drive cylinder 52 is hinged to the push block 41.

[0036] By controlling the extension and retraction of the drive rod through the drive cylinder 52, the push block 41 is pushed to rotate around the adjustment rod 51 in the horizontal or vertical direction, thereby controlling the spray direction of the cooling nozzle 31 and improving the cooling effect.

A wireless temperature sensor 8 is fixed on the outer shell of the drill bit chuck 7. The chamfering device for machining mechanical parts is equipped with a controller. The controller is electrically connected to the wireless temperature sensor 8 and the drive cylinder 52.

[0038] The wireless temperature sensor 8 senses the temperature near the chamfered drill bit 23 and transmits the data to the controller. The controller controls the operation of the drive cylinder 52 based on the data, and then controls the rotation of the cooling nozzle 31 to achieve effective temperature management and cooling.

[0039] Working principle: The drive motor 24 starts, driving the chamfering spindle 22 to rotate, which in turn drives the chamfering drill bit 23 to perform processing. During the processing, the cooling component 3 delivers gas to the gas tank 32 through the air pump 33, and the cooling nozzle 31 sprays the cooling gas onto the chamfering drill bit 23 and the processing area. The wireless temperature sensor 8 on the outer shell of the drill bit holder 7 monitors the temperature around the chamfering drill bit 23 in real time and transmits the temperature data to the controller. The controller adjusts the action of the regulating component 5 according to the temperature change. The regulating component 5 changes the extension and retraction action of the drive cylinder 52, which drives the push block 41 to rotate the first connecting block 4, so that the cooling nozzle 31 can adjust the spray direction as needed to improve the overall cooling effect.
