[0002] When processing a gear shaft, it needs to be polished, and a polishing device is required. For example, the patent with announcement number CN205074909U discloses a double-station polishing machine that is convenient for placing a gear shaft. It discloses that during the polishing process, the gear shaft and the polishing wheel will produce a lot of metal powder. Through the exhaust fans set on both sides of the frame, the exhaust fans are set one by one with the polishing wheel, which can timely remove such metal powder and achieve the purpose of cleaning the production environment. However, directly discharging the powder will cause environmental pollution, affecting the surrounding environment of the processing site and the health of personnel; in response to this problem, the Chinese utility model with application number 202221895411.8 proposes a gear shaft polishing device, including a grinding component, a workbench and a cleaning component, wherein the grinding component is arranged above the workbench, and the cleaning component includes a cylinder, a filter part, a fan and a receiving cylinder, and the cylinder is provided with a first air inlet and a second air inlet arranged opposite to each other, and the first air inlet and the second air inlet are arranged to be inclined downward, and a liquid is provided below the cylinder, and the filter part is arranged above the cylinder, and the filter part has an extension extending into the cylinder, and the bottom of the extension part has an air inlet, and the first air inlet and the second air inlet are located on both sides of the extension part, and a filter component is provided in the filter part, and the filter component is connected to the extension part, and the fan is arranged at the top of the filter part, and the receiving cylinder is arranged below the cylinder, and a control valve is provided at the bottom of the cylinder. The utility model can enable the debris generated by grinding to enter the cylinder for filtration, thereby preventing the debris from contaminating the workbench and affecting the polishing quality; at the same time, it can avoid environmental pollution; but the problems existing in the use of the device are:

DETAILED DESCRIPTION

[0019] The following will be combined with the attached embodiment of the utility model Figure 1-Figure 3 , clearly and completely describe the technical solutions in the embodiments of the utility model.

A grinding mechanism 2 is fixedly connected to the first mounting platform 1, and a filter cartridge 9 is fixedly connected to the second mounting platform 8. A workbench 3 is fixedly arranged below the grinding mechanism 2. A recovery chamber 4 is provided inside the workbench 3. A chip removal port 5 and a cleaning port 6 are respectively provided at one end and the bottom of the recovery chamber 4. A guide pipe 7 with an adsorption mechanism is fixedly connected to the bottom end of the cleaning port 6. A guide chamber 11 is provided inside the filter cartridge 9. A chip collection box 10 is connected to the bottom of the filter cartridge 9. The guide pipe 7 is also connected to the filter cartridge 9. A first filter plate 12 is embedded in the recovery chamber 4. The first filter A sliding head 14 is fixedly connected to the outer surface of the plate 12, and a limiting plate 13 is fixedly connected to the inner walls on both sides of the recovery chamber 4. A sliding groove 15 is provided on the surface of the limiting plate 13. The first filter plate 12 and the sliding plate 13 are movably connected. A second filter plate 16 is embedded in the interior of the filter cartridge 9. At the same time, an exhaust port 17 is provided on the side of the filter cartridge 9. When filtering, the powder gas is discharged from the upper position of the filter cartridge 9 into the guide chamber 11 in the filter cartridge 9 through the guide pipe 7, and a vortex is formed in the guide chamber 11. A part of the impurity particles are concentrated in the chip box 10 due to their weight, while the other part moves upward with the airflow and contacts the second filter plate 16 for interception. The gas passes through the second filter plate 16 and is discharged from the exhaust port 17.

[0021] In the embodiment of the utility model, the chip discharge port 5 is opened horizontally and is located at one side of the first filter plate 12. The first filter plate 12 is inclined in the recovery chamber 4. The two ends of the first filter plate 12 and the inner wall of the recovery chamber 4 are clamped. The sliding head 14 is located at both sides of the bottom of the first filter plate 12 and is slidably embedded in the sliding groove 15. A spring is provided on the inner side of the sliding groove 15. The limiting plate 13 corresponds to the sliding head 14 and is arranged in two groups in a circular shape. The sliding groove 15 is opened at an angle. The chip discharge port 5 is used to collect and discharge the pretreated particulate impurities in the recovery chamber 4. The pretreatment effect is achieved by the inclined first filter plate 12. The first filter plate 12 is buffered and protected by the sliding head 14 in cooperation with the limiting plate 13 and the sliding groove 15 on the surface of the limiting plate 13.

[0022] After the powder gas enters the recovery chamber 4, it is guided into the guide pipe 7 through the adsorption mechanism matched with the guide pipe 7. In this process, large particles of impurities are filtered through the inclined first filter plate 12. The filtered large particles of impurities are concentrated along the first filter plate 12 at the chip discharge port 5 to facilitate subsequent cleaning. At the same time, when the adsorption mechanism matched with the guide pipe 7 generates suction, the first filter plate 12 can be buffered according to the suction size under the sliding head 14 and the sliding groove 15 matched with the spring, thereby extending the service life of the first filter plate 12.

[0023] The filter cartridge 9 is vertically arranged, and the position communicating with the guide pipe 7 is located at the upper outer side of the filter cartridge 9. The two sides of the guide cavity 11 are arranged in an arc-shaped outward protrusion. The chip box 10 is arranged horizontally in a rectangular shape at the bottom of the filter cartridge 9. The second filter plate 16 is located in the upper inner part of the filter cartridge 9 and is located above the connection position between the guide pipe 7 and the filter cartridge 9. The exhaust port 17 is also located above the second filter plate 16. The guide cavity 11 arranged in an arc-shaped manner on both sides achieves the effect of making the powder airflow entering the filter cartridge 9 swirl-like, which is convenient for separating the impurity particles therein. The second filter plate 16 achieves the effect of filtering and intercepting the impurity particles, and the chip box 10 achieves the effect of concentrating the impurity particles.
