When the closed cover 30 is in a suspended state, the bottom end of the closed cover 30 is located below the bottom end of the drill pipe 20. The closed cover 30 is arranged outside the drill pipe 20. An annular inclined plate 31 is fixedly installed on the inner bottom surface of the closed cover 30. There is a gap between the top end of the annular inclined plate 31 and the inner surface of the closed cover 30. A water outlet part 301 is arranged on the closed cover 30; A water delivery assembly, which is composed of a water pump 50, a first water pipe 51 and a connecting ring 52; wherein, the water pump 50 is fixedly installed on the lifting platform 13. One end of the first water pipe 51 is fixedly connected to the water outlet end of the water pump 50. The connecting ring 52 is rotatably installed on the outer surface of the adapter block 41. An annular cavity is arranged inside the connecting ring 52, and this annular cavity is communicated with the third flow channel 411. The connecting ring 52 is fixedly connected to the bottom end of the lifting platform 13 through a connecting rod 521. The other end of the first water pipe 51 is fixedly connected to the connecting ring 52; Wherein, a first movable cavity 202 is opened at the bottom end of the drill pipe 20. A movable head 21 is slidably installed in the first movable cavity 202. A limiting ring 213 is fixedly installed at the top end of the movable head 21. A third flow channel 411 is opened in the adapter block 41, and this third flow channel 411 is communicated with the inside of the connecting ring 52. A first flow channel 201 is opened in the drill pipe 20. A second flow channel 211 is opened in the movable head 21. A plurality of horizontal flow channels 212 are also opened in the movable head 21, and the plurality of horizontal flow channels 212 are communicated with the second flow channel 211; When machining a metal workpiece, the lifting platform 13 drives the drill pipe 20 and the closed cover 30 to descend synchronously. The closed cover 30 will contact the upper surface of the metal workpiece first, and finally the drill pipe 20 will cut and drill the metal workpiece. The generated iron filings are blocked by the inner surface of the closed cover 30, and there will be no situation of iron filings splashing. And the water pump 50 conveys water into the connecting ring 52, and then the water is sprayed on the metal workpiece through the third flow channel 411, the first flow channel 201 and the second flow channel 211 in sequence to cool the drill pipe 20; After the drill pipe 20 contacts the metal workpiece, the movable head 21 is blocked by the metal workpiece.

After the drilling is completed, the drill pipe 20 will move upward with the lifting table 13, while the closed cover 30 still adheres to the surface of the metal workpiece, and the length of the telescopic rod will gradually increase. When the bottom end of the drill pipe 20 is above the metal workpiece, under the action of its gravity, the bottom end of the movable head 21 will drop to the outside of the drill pipe 20. When the bottom end of the movable head 21 and the surface of the metal workpiece are at the same height, the lifting table 13 stops moving, and water can be sprayed out through the second flow channel 211 and the plurality of horizontal flow channels 212. At this time, the drill pipe 20 is still rotating. The second flow channel 211 sprays water into the hole groove of the metal workpiece, which can impact the iron chips in the hole groove, so that the iron chips move to the surface of the metal workpiece with the water, and the plurality of horizontal flow channels 212 impact the iron chips on the surface of the metal workpiece, so that the iron chips cross the annular inclined plate 31 and enter the inside of the closed cover 30. Therefore, when cutting and drilling the metal workpiece, not only will there be no situation of iron chip splashing, but also the generated iron chips can be collected, there is no need to clean the metal workpiece, nor to clean the machine tool 10 regularly, which reduces the use difficulty of this drill press.

[0021] A plurality of downwardly inclined first inclined flow channels 203 are formed in the drill pipe 20, and the tops of the plurality of first inclined flow channels 203 are communicated with the top of the first movable cavity 202; a guide rod 23 is fixedly installed on the limit ring 213, a first guide surface 231 is provided on the guide rod 23, a guide block 24 is slidably installed in the drill pipe 20, a second guide surface 241 is provided at one end of the guide block 24, and an arc surface 242 is provided at the other end of the guide block 24; The first guide surface 231 is always in contact with the second guide surface 241. When cutting and drilling the metal workpiece, the arc surface 242 will contact the edge of the hole groove of the metal workpiece. The guide block 24 under the action of the force will slide into the drill pipe 20 and push the movable head 21 upward. The limit ring 213 blocks the tops of the plurality of first inclined flow channels 203. Therefore, during the cutting and drilling process, water will not be discharged from the plurality of first inclined flow channels 203. Furthermore, during the drilling process, the water discharged from the second flow channel 211 can normally send the iron chips in the hole groove to the surface of the metal workpiece; After the drilling is completed and the drill pipe 20 moves above the metal workpiece, the movable head 21 moves downward under its own gravity and the pressure of the water discharged from the first flow channel 201. The water in the first flow channel 201 will enter the first movable cavity 202, and then multiple first inclined flow channels 203 can spray the water and spray it on the surface of the metal workpiece. Cooperating with multiple horizontal flow channels 212 can more efficiently send the iron chips into the inside of the closed cover 30; Further, the drill pipe 20 is provided with a plurality of second inclined flow channels 204 that incline upward. The inside of the drill pipe 20 is also provided with a second movable cavity 205. The bottom ends of the plurality of second inclined flow channels 204 are communicated with the bottom of the second movable cavity 205. The second movable cavity 205 is arranged between the first flow channel 201 and the first movable cavity 202. A sealing ring 22 is arranged in the second movable cavity 205.

The plurality of second inclined flow channels 204 are beneficial for the iron chips in the hole groove to quickly reach the upper surface of the metal workpiece; When the drill pipe 20 is above the metal workpiece, the bottom end of the movable head 21 is located outside the drill pipe 20. At this time, the sealing ring 22 is located at the bottom end of the second movable cavity 205, and the sealing ring 22 seals the bottom ends of the plurality of second inclined flow channels 204. Embodiment

[0022] An annular pipe 62 is fixedly installed at the bottom end of the lifting table 13. The telescopic rod is composed of a sleeve 60 and an inner rod 61. The inner rod 61 is slidably connected to the sleeve 60. The top end of the sleeve 60 is fixedly connected to the annular pipe 62. The inside of the sleeve 60 is communicated with the inside of the annular pipe 62. The connecting ring 52 is communicated with the inside of the annular pipe 62 through a second water pipe 64. An installation plate 36 is fixedly installed on the closed cover 30. The bottom end of the inner rod 61 is fixedly connected to the installation plate 36; Since the closed cover 30 only adheres to the metal workpiece by its own gravity, the water impact on the iron chips is likely to affect the stability of the closed cover 30 adhering to the metal workpiece. The water in the connecting ring 52 can enter the annular pipe 62 through the second water pipe 64 and finally enter the inside of each sleeve 60. The inner rod 61 is then subjected to the thrust of the water, so that the closed cover 30 stably adheres to the metal workpiece; Inside the closed cover 30, an annular plate 32 and an annular connecting plate 33 are fixedly installed. An inclined surface is provided on the annular plate 32. A third channel 611 is opened in an inner rod 61. A third water pipe 63 is fixedly installed at the bottom end of the inner rod 61. A first channel 321 is opened in the annular plate 32. An annular channel 331 is opened in the annular connecting plate 33. The annular channel 331 communicates with the first channel 321. The bottom end of the third water pipe 63 communicates with the first channel 321. A spray channel 332 is opened in the annular connecting plate 33 and at the lowest point of the inclined surface on the annular plate 32. The spray channel 332 communicates with the annular channel 331; Multiple horizontal and direct flow channels 212 wash the iron filings onto the surface of the annular plate 32. Since the water outlet part 301 is located at the bottom end of the inclined surface, the water on the annular plate 32 flows towards the bottom end of the inclined surface. The flowing water can drive the iron filings to move towards the bottom end of the inclined surface together, so that the iron filings are concentrated at the bottom end position of the inclined surface; In order to smoothly remove the iron filings from the inside of the closed cover 30, a guiding pipe 35 is fixedly installed on the closed cover 30. The opening end of the guiding pipe 35 faces the spray channel 332. A conveying pipe 70 is fixedly installed on the mounting plate 36. The bottom end of the conveying pipe 70 is fixedly connected to the guiding pipe 35. The mounting plate 36 is fixedly connected to a collection tank 74 through a fixing rod 741. The top end of the conveying pipe 70 is fixedly connected to the top end of the collection tank 74. A rotating rod 72 is rotatably installed inside the conveying pipe 70. A spiral blade 71 is fixedly installed on the outer surface of the rotating rod 72. A motor 73 is fixedly installed on the top end of the collection tank 74 through a mounting rod 731. The output end of the motor 73 is fixedly connected to the top end of the spiral blade 71; The water in a sleeve 60 will enter the third water pipe 63 through the third channel 611, then enter the annular channel 331 through the first channel 321, and finally be sprayed out through the spray channel 332. Since the spray channel 332 is located at the lowest point of the inclined surface, it can wash the iron filings concentrated at the bottom end of the inclined surface into the guiding pipe 35. The iron filings enter the inside of the conveying pipe 70 through the guiding pipe 35. The motor 73 drives the spiral blade 71 to rotate. The spiral blade 71 conveys the iron filings to the top end of the conveying pipe 70 and finally into the inside of the collection tank 74 to collect the generated iron filings. When a certain amount of iron filings are stored inside the collection tank 74, the lid at the bottom end of the collection tank 74 can be removed to recycle the iron filings; It should be noted that the height of the top end of the annular plate 32 is lower than the height of the top end of the annular inclined plate 31, so that the iron filings reaching the annular plate 32 will not return to the annular inclined plate 31 again; Some iron filings are relatively large in volume, and relying solely on the flow of water cannot transport all the iron filings to the bottom of the inclined plane. To solve this problem, a fixing block 34 is fixedly installed on the annular plate 32 at the top of the inclined plane. A concentrating cavity 341 is formed inside the fixing block 34. A plurality of downwardly inclined spray holes 342 are formed on both side surfaces of the fixing block 34. A second channel 322 is also formed inside the annular plate 32. The first channel 321 is connected to the concentrating cavity 341 through the second channel 322. The water in the first channel 321 can enter the concentrating cavity 341 through the second channel 322 and finally be discharged through the plurality of spray holes 342, spraying the water on the annular plate 32 to accelerate the flow rate of the water on the annular plate 32, and it is not easy for the iron filings to fail to reach the bottom of the inclined plane smoothly.
