Example:

Please refer to Figure 1-4, a CNC CNC machine tool that is resistant to debris splashing, suitable for CNC CNC machine tools with models VMC650, VMC850 or VMC1060, including a casing 1, and a control system is provided on the casing 1 for controlling the entire When the machine tool is running, a water supply mechanism is provided on the back of the casing 1. A cantilever 2 is fixedly installed on the upper surface of the casing 1. The cantilever 2 is equipped with a spindle driven by a servo system and a tool installed at the lower end of the spindle. This technical solution is an existing technical solution. Technology, not shown in the figure, one end of the cantilever 2 extends into the inside of the casing 1, and a cooling water pipe 3 is fixedly installed on the outside of the cantilever 2 inside the casing 1. One end of the cooling water pipe 3 is connected to the water supply mechanism, and the cantilever 2 extends A water outlet cup 4 is fixedly installed at one end inside the casing 1. The water outlet cup 4 is a cup-shaped structure with an opening facing downwards and is coaxial with the cantilever 2.

The other end of the cooling water pipe 3 runs through the water outlet cup 4 and the inner flange ring 5. The cooling water pipe 3 is fixedly installed with branch pipes 6 on both sides. In the gap between the flange rings 5, the blank is first clamped to the workbench. During cutting, the servo system moves the workbench and the spindle of the cantilever 2 to drive the tool to cut the blank, and the cut debris forms small pieces of iron chips. , and is thrown away. At the same time, the water supply mechanism is started to pump cooling water to the cooling water pipe 3. The water is sprayed to the processing point of the blank for cooling. Part of the cooling water is diverted through the diverter pipe 6 and sent to the water outlet cup 4. Since the water outlet cup The gap between 4 and the inner flange ring 5 is narrow, so that the diverted water gradually fills the gap between the water outlet cup 4 and the inner flange ring 5, and then distributes along the inner wall of the water outlet cup 4 and sprays downward, forming a water curtain surrounding the processing point. , circumferentially blocks the thrown iron filings, drives the iron filings to fall to the lower wall of the casing 1, facilitates collection, reduces leakage of iron filings, and reduces the situation where the iron filings block the view of the processing personnel when the CNC machine tool processes the workpiece.

The impact effect will wash away the thrown iron chips with a larger impact, further shortening the path of the thrown iron chips.

Referring to Figures 2 and 4, there are multiple guide plates 9 distributed along the circumferential array on the inner wall of the water outlet cup 4. The upper end of the guide plate 9 is fixedly connected to the lower surface of the inner flange ring 5, and the multiple guide plates 9 are used to guide out the water. The diverted water in the water cup 4 causes the diverted water to shoot vertically downward toward the iron filings, thereby reducing the diverted water deviating from the workpiece and conducive to the concentration of the diverted water.

The cut chips form small pieces of iron chips and are thrown away. The booster pump 8 is started through the operation control system to suck the cooling water in the cooling pool 7 and pump it to the cooling water pipe 3 to pump the cooling water to the cooling water pipe 3. The water is injected to the processing point of the blank for cooling and is diverted through the shunt. The pipe 6 diverts part of the cooling water and sends it into the water outlet cup 4. Due to the narrow gap between the water outlet cup 4 and the inner flange ring 5, the diverted water gradually fills the gap between the water outlet cup 4 and the inner flange ring 5, and then flows along the edge of the water outlet cup 4. The inner wall is distributed and sprays downward, which can form a water curtain surrounding the processing point, circumferentially shield the thrown iron chips, and wash away the thrown iron chips with a large impact, further shortening the path of the thrown iron chips, and driving the The iron filings fall to the lower wall of the casing 1 for easy collection, thereby reducing the leakage of iron filings and reducing the situation where the iron filings block the view of the processing personnel when the CNC machine tool processes the workpiece.
