[0021] In this embodiment, the adsorption mechanism 3 includes an inner box 301, a plurality of adsorption components 302, an exhaust pipe 303 and an air pump 304. The upper parts of the plurality of adsorption components 302 are installed on the upper part of the inner box 301, the outer periphery of the inner box 301 is arranged in the middle of the outer box 1, and a notch is arranged in the middle of the lower side of the four sides of the inner box 301. One end of the exhaust pipe 303 passes through the notch and extends into the inner box 301. The other end of the exhaust pipe 303 passes through the wall shell of the outer box 1 and is fixedly connected to the input end of the air pump 304. The air pump 304 is installed on the outside of the outer box 1. Filtered water is arranged inside the outer box 1. The filtered water liquid level is located at the bottom of the adsorption component 302 and the upper part of the notch. The end port of the exhaust pipe 303 away from the air pump 304 is higher than the filtered water liquid level. A groove 4 is provided in the middle of the four sides. The adsorption component 302 comprises an adsorption cylinder 3021, a lower limit ring 3022, a spring 1 3023, a slag discharge component 3024, an upper limit ring 3025 and a sealing rubber pad 3026. The outer periphery of the upper limit ring 3025 is fixedly connected to the upper end of the inner side of the adsorption cylinder 3021, the outer periphery of the lower limit ring 3022 is fixedly connected to the lower end of the inner side of the adsorption cylinder 3021, the outer periphery of the slag discharge component 3024 is slidably connected to the inside of the adsorption cylinder 3021, the upper end of the spring 1 3023 is fixedly connected to the lower part of the slag discharge component 3024, the lower end of the spring 1 3023 is fixedly connected to the upper part of the lower limit ring 3022, and the lower part of the sealing rubber pad 3026 is installed on the upper end of the adsorption cylinder 3021.
[0022] Specifically, the inner box 301 can be easily taken out from the outer box 1 through the groove 4, which is convenient for cleaning the inside of the outer box 1. The workpiece to be processed is placed in the middle of the inner box 301, and then the air pump 304 is driven to extract the air inside the inner box 301 through the exhaust pipe 303. Since the bottom of the inner box 301 is sealed with filtered water, the slag discharge assembly 3024 compresses the spring 3023 and moves downward. When the upper part of the adsorption cylinder 3021 is sealed with the workpiece to be processed, the upper part of the piston 30241 will be in a negative pressure state, thereby fixing the workpiece to be processed on the upper part of the inner box 301 to prevent the workpiece to be processed from moving during processing, thereby improving the processing accuracy.
[0023] In this embodiment, the slag discharge assembly 3024 includes a piston 30241, a drainage port 30242, a drainage annular groove 30243, a stopper 30244 and a spring 2 30245. The drainage port 30242 is provided in the middle of the upper and lower sides of the piston 30241. The outer periphery of the piston 30241 is slidably connected to the inner wall of the adsorption cylinder 3021. The drainage annular groove 30243 is provided in the upper and middle part of the piston 30241. The upper and lower drainage ports 30242 and the drainage annular groove 30243 are connected to each other. The outer periphery of the stopper 30244 is slidably connected to the middle of the drainage annular groove 30243. The spring 2 30245 is provided in the middle of the piston 30241. The upper part of spring 2 30245 is fixedly connected to the lower part of block 30244, and the cleaning mechanism 5 includes a water pump 501, a drain pipe 502, a water inlet pipe 503 and a drain cylinder 504. One end of the water inlet pipe 503 is installed at the input end of the water pump 501, and the other end of the water inlet pipe 503 passes through the side wall of the outer box 1 and is fixedly connected to a filter. The filter is immersed in the filtered water, one end of the drain pipe 502 is fixedly connected to the output end of the water pump 501, and the other end of the drain pipe 502 passes through the wall shell of the outer box 1 and is fixedly connected to the lower end of the drain cylinder 504. The upper end of the drain cylinder 504 is arranged in the middle of the inner box 301.
[0024] Specifically, the water pump 501 is driven to transport the filtered water in the outer box 1 to the inside of the drain tube 504 through the drain pipe 502 and the water inlet pipe 503, so that the filtered water flows out of the drain tube 504, thereby making the filtered water flush the dust and impurities on the inner box 301. Under the continuous adsorption of the air pump 304, when the spring 1 3023 is compressed to the limit, the stopper 30244 will move downward and compress the spring 2 30245, and at the same time block the lower part of the drainage ring groove 30243 and the lower drainage port 30242, ensuring that the slag discharge assembly 302 4. When the workpiece to be processed is processed, some impurities will enter the drainage groove 30243. After the processing is completed, the air pump 304 is turned off, and the spring 2 30245 resets the stopper 30244, so that the stopper 30244 blocks the upper drainage port 30242 to ensure the sealing of the slag discharge component 3024. At the same time, the impurities and filtered water in the drainage groove 30243 are discharged from the lower part of the drainage groove 30243 to ensure the cleanliness of the upper part of the adsorption component 302 and prevent the adsorption component 302 from being blocked by impurities.
[0025] Working principle:
[0026] The inner box 301 can be conveniently taken out from the outer box 1 through the groove 4, so as to facilitate cleaning of the inner box 1. The workpiece to be processed is placed in the middle of the inner box 301, and then the air pump 304 is driven to extract the air inside the inner box 301 through the exhaust pipe 303. Since the bottom of the inner box 301 is sealed with filtered water, the slag discharge component 3024 compresses the spring 3023 and moves downward. When the upper part of the adsorption cylinder 3021 is sealed with the workpiece to be processed, the upper part of the piston 30241 will be in a negative pressure state, thereby fixing the workpiece to be processed on the upper part of the inner box 301 to prevent the workpiece to be processed from moving during processing, thereby improving the processing accuracy. The water pump 501 is driven to transport the filtered water inside the outer box 1 to the inside of the drain cylinder 504 through the drain pipe 502 and the water inlet pipe 503, so that the filtered water flows out of the drain cylinder 504, thereby allowing the filtered water to flow into the inner box 301. The dust and impurities on the surface are washed away. Under the continuous adsorption of the air pump 304, when the spring 1 3023 is compressed to the limit, the stopper 30244 will move down and compress the spring 2 30245, and at the same time block the lower part of the drainage ring groove 30243 and the lower drainage port 30242 to ensure the sealing of the slag discharge component 3024. When the workpiece to be processed is processed, some impurities will enter the drainage ring groove 30243. After the processing is completed, the air pump 304 is turned off, and the spring 2 30245 resets the stopper 30244, so that the stopper 30244 blocks the upper drainage port 30242 to ensure the sealing of the slag discharge component 3024. At the same time, the impurities and filtered water in the drainage ring groove 30243 are discharged from the lower part of the drainage ring groove 30243 to ensure the cleanliness of the upper part of the adsorption component 302 and prevent the adsorption component 302 from being blocked by impurities.
