The device can break chips during the turning tool machining process, and has the characteristics of convenient chip breaking and strong applicability".

[0004] However, the above-mentioned public document discloses a tool with a turntable protrusion that can break chips. The main consideration is that the chip will hit the protrusion during the chip discharge process, and the bending angle of the chip will increase.

The active chip breaking of the chips generated during the cutting process is not considered, which leads to insufficient flexibility, failure to handle the chips in time, and easy accumulation. This accumulation not only affects the stability of the cutting process, but also may reduce work efficiency. It is necessary to develop an auxiliary chip breaking structure for superhard turning tools. Summary of the invention

When the debris is cut off, the movement of the driving component will drive the turntable 5 to rotate, and the rotation of the turntable 5 will drive the chip breaker 6 to move. When the chip breaker 6 moves in a circle, when the debris comes into contact with the moving chip breaker 6, the chip breaker 6 can break the debris to avoid the entanglement of the debris and the decrease in the cutting effect of the cutting tool 2. According to the amount of debris generated, the driving component can adapt the movement of the chip breaker 6 to adjust the rotation speed of the chip breaker 6, so that the movement speed of the chip breaker 6 can be adaptively adjusted according to the amount of debris to break the debris.

The speed of the output end of the driving motor 12 is adjusted by changing the supply voltage. The higher the voltage, the faster the speed. The speed of the driving motor 12 can be adaptively adjusted according to the amount of debris. The driving motor 12 drives the driving wheel 13 to rotate when it works. When the driving wheel 13 rotates, it will drive the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 will drive the turntable 5 to rotate. The turntable 5 can drive the chip breaker 6 to move to break the debris generated by cutting.

[0028] See also Figure 1 and Figure 6 The cleaning component includes a diverter groove 18 and a spray hole 19. The diverter groove 18 is embedded in the protective cover 7, and the diverter groove 18 is located above the turntable 5. The spray hole 19 array is arranged on the diverter groove 18. The diverter groove 18 is connected with the output end of the fan 14 through a pipeline. After the wind flow generated by the movement of the fan 14 enters the diverter groove 18, it will flow to the location of the cutting tool 2 through the spray hole 19 to remove the debris and impurities adsorbed on the cutting tool 2.

[0030] Working principle, firstly, after the turning tool 1 is fixedly installed on the lathe, the turning tool 1 can perform cutting processing on the workpiece through the cutting tool 2. When the cutting tool 2 cuts the workpiece, debris will be generated. When the debris is wrapped around the cutting tool 2, it will hinder the smooth cutting of the cutting tool 2, resulting in a decrease in the cutting efficiency of the tool.

In order to avoid the entanglement of debris causing the cutting effect of the cutting knife 2 to decrease, the driving motor 12 is moved to adapt to adjust the rotation speed of the chip breaker 6 according to the amount of debris generated, so that the movement speed of the chip breaker 6 can be adaptively adjusted according to the amount of debris to break the debris. The driving motor 12 will drive the driven shaft 16 to rotate, and the driven shaft 16 will drive the impeller 15 to rotate. The rotation of the impeller 15 will cause the fan 14 to move and generate wind force. After the wind force generated by the fan 14 flows into the diverter groove 18, it will flow to the location of the cutting knife 2 through the spray hole 19, and the debris and impurities adsorbed on the cutting knife 2 will be removed, further avoiding the debris adsorbed on the cutting knife 2 and affecting the cutting force of the cutting knife 2.
