The second motor 602 is fixed to the outer wall on one side of the retaining frame 601. The retaining frame 601 prevents the debris and cutting fluid generated during processing from splashing. The second motor 602 drives the fourth lead screw 603 to rotate, thereby driving the scraping plate 604 to slide along both sides.

[0030] In this embodiment: The filtering mechanism 7 includes a filtering box 701 for receiving the mixture of debris and cutting fluid. A filter plate 703 is provided in the middle of the filtering box 701. Square holes for allowing the filter plate 703 to pass through are formed on the outer side walls on both sides of the filtering box 701. A handle for pulling is fixed to the other side of the filter plate 703. A water pump 704 for upwardly conveying the filtered cutting fluid is fixedly connected to the bottom of the filtering box 701.

The filtering box 701 receives the mixture of the cleaned debris and cutting fluid. The filter plate 703 separates the debris and the cutting fluid. The water pump 704 upwardly conveys the filtered cutting fluid to the vicinity of the drill bit 5 through the water delivery pipe 702. The filter plate 703 is pulled through the handle on the filter plate 703 so that the debris on it is scraped off through the square hole and falls into the other side of the partition plate 705. The partition plate 705 separates the filtered debris and cutting fluid in the filtering box 701 for separate recovery.

[0031] In this embodiment: The processing mechanism 2 includes a base 202 fixed to the top of the workbench 1. A first sliding seat 204 is slidably connected to the front side of the top of the base 202 in the front-rear direction. A first lead screw 203 is threadedly connected to the bottom of the first sliding seat 204. The input end of the first lead screw 203 is fixedly connected to a first handle 201. Two second sliding seats 3 are slidably connected to the top of the first sliding seat 204 along both sides. A second lead screw 206 is threadedly connected to the bottom of the second sliding seat 3. The input end of the second lead screw 206 is fixedly connected to a second handle 205. A support plate 208 is fixed to the rear side of the top of the base 202. A third sliding seat 210 is slidably connected to the support plate 208 in the vertical direction. A third lead screw 209 is threadedly connected to the bottom of the third sliding seat 210. The input end of the third lead screw 209 is fixedly connected to a third handle 207. The third sliding seat 210 is fixedly connected to the first motor 4. The top of the second sliding seat 3 is connected to a bottom plate 213 through a pin. Cylinders 212 are fixed to both sides of the bottom plate 213. Clamping plates 211 for clamping the pump cover are fixed to the output ends of the two cylinders 212. The first handle 201 drives the first lead screw 203 to rotate, thereby driving the first sliding seat 204 to slide in the front-rear direction. The second handle 205 drives the second lead screw 206 to rotate, thereby driving the second sliding seat 3 to slide along both sides. The third handle 207 drives the third lead screw 209 to rotate, thereby driving the third sliding seat 210 to slide in the vertical direction. The two cylinders 212 drive the two clamping plates 211 to approach each other to clamp the pump cover.

[0032] Working principle: The bottom plate 213, together with the two cylinders 212 and the clamping plates 211, is connected to the second sliding seat 3 by a pin. Then, the pump cover is placed between the two clamping plates 211. Start the two cylinders 212 to drive the two clamping plates 211 to move closer to clamp the pump cover. After that, rotate the first handle 201 to drive the first lead screw 203 to rotate, thereby driving the first sliding seat 204 to slide in the front-rear direction to adjust the position of the first sliding seat 204. Rotate the second handle 205 to drive the second lead screw 206 to rotate, thereby driving the second sliding seat 3 to slide along both sides to adjust the position of the second sliding seat 3. After the position is adjusted, rotate the third handle 207 to drive the third lead screw 209 to rotate, thereby driving the third sliding seat 210 to slide in the vertical direction to process the pump cover according to the processing requirements. After the pump cover is processed, start the two cylinders 212 to release the processed pump cover, and remove the bottom plate 213, together with the two cylinders 212 and the clamping plates 211. Start the second motor 602 to drive the fourth lead screw 603 to rotate counterclockwise, thereby driving the scraper 604 to slide from both sides to the other side. During the sliding process, the scraper 604 gradually brings the mixture of debris and cutting fluid to the other side of the baffle 601 and drops it into the filter box 701. The debris remains on the filter plate 703, while the cutting fluid filters and falls to the bottom of the filter box 701. The filtered cutting fluid is pumped upward through the water delivery pipe 702 to the vicinity of the drill bit 5 by the water pump 704 to achieve recycling. Pull the filter plate 703 to the other side so that the debris on it is scraped off through the square holes and falls into the other side of the partition 705. Finally, the second motor 602 drives the fourth lead screw 603 to rotate clockwise, thereby driving the scraper 604 to slide to one side for resetting.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
