[0020] Working principle: When performing the grinding work, first connect the entire device to the external safe mains power, and put the gear to be processed on the positioning piece 26, and at the same time add a certain amount of coolant into the liquid supply tank 10; then control the auxiliary positioning cylinder 24 to start, and after the auxiliary positioning cylinder 24 is started, it will drive the auxiliary positioning piece to move toward the gear, so that the two auxiliary positioning pieces can further assist in positioning the gear from the outside of the gear; then control the grinding motor 3, the translation cylinder 19 and the blower connected to the blower pipe 25 to start, After the grinding motor 3 is started, it will drive the grinding wheel 2 to rotate; and after the translation cylinder 19 is started, it will drive the translation seat 20 to move toward the liquid collecting tank 5. During the movement of the translation seat 20, it will move the positioning seat 4 and the gear on the positioning seat 4 together, and finally make the gear contact with the grinding wheel 2, and use the grinding wheel 2 to grind the gear; during the grinding process, the water pump on the liquid supply tank 10 is always controlled to lift the internal coolant to the spray head 9, and the spray head 9 is used to spray the grinding position on the gear for cooling. The liquid will flow to the filter screen 6 on the liquid collecting tank 5, and the filter screen 6 will be used to filter the debris carried by the coolant, and the filtered coolant will flow into the liquid supply tank 10 through the position where the bottom end of the liquid collecting tank 5 is connected to the liquid supply tank 10 for reuse, thereby reducing the grinding cost; when the grinding of one position of the gear is completed, the translation cylinder 19 is first controlled to stop, so that the translation seat 20 drives the gear to separate from the grinding wheel 2, and then the rotation motor 21 is controlled to start for a certain time according to the position that needs to be ground. The rotation motor 21 starts After that, it will drive the rotating seat 22 to rotate, and after the rotating seat 22 rotates, it will drive the gear to rotate. After it rotates to a suitable angle, the translation cylinder 19 is controlled to start again. After the translation cylinder 19 is started, it will push the gear to contact the grinding wheel 2 again to perform grinding. Repeat this action until all positions on the gear are ground. During the whole process, the gas in the blast pipe 25 will blow air onto the gear through the air outlet, so that the coolant on the surface of the gear can be dried, and there is no need for subsequent drying work, which improves work efficiency.

[0021] When there is a lot of debris filtered on the filter 6 and it affects the filtration rate, it is only necessary to control the servo motor 16 to start in the forward direction. After the servo motor 16 starts in the forward direction, it will drive the ball screw 13 to rotate. After the ball screw 13 rotates, it will drive the slider 15 to move toward the dirt collecting plate 11. During the movement of the slider 15, the scraper 7 will be driven to move. During the movement of the scraper 7, the slider 15 at the other end of the scraper 7 will be moved to slide on the slide rail 14, so that the scraper 7 can be stably scraped on the filter 6. During the movement of the scraper 7, the debris on the filter 6 will be scraped onto the dirt collecting plate 11; thereby, the filtration rate of the filter 6 can be guaranteed and the work efficiency is improved.
