[0027] See also Figure 1-4 The utility model provides a technical solution: a coolant recovery device for an end milling machine, comprising a milling machine 1, a recovery box 2 is fixedly installed on the upper surface of the milling machine 1, and a filter and dirt collection component 3 and a dredging component 4 are arranged on the inner wall of the recovery box 2;

[0028] The filtering and collecting sewage assembly 3 includes a reciprocating screw 31, one end of the reciprocating screw 31 is rotatably connected to the inner side wall of the recycling box 2, and the other end of the reciprocating screw 31 extends to the outside of the side wall of the recycling box 2, a mounting cover 32 is fixedly installed on the side wall of the recycling box 2, a driving motor 33 is fixedly installed on the inner wall of the mounting cover 32, the other end of the reciprocating screw 31 is fixedly connected to the output end of the driving motor 33, a threaded sleeve 34 is threadedly installed on the outer surface of the reciprocating screw 31, a scraper 35 is fixedly installed on the lower surface of the threaded sleeve 34, a filter plate 36 is fixedly installed on the inner wall of the recycling box 2, the lower surface of the scraper 35 is in contact with the upper surface of the filter plate 36, the upper surface of the filter plate 36 is provided with two sewage discharge grooves 37, a mounting plate 38 is fixedly installed on the lower surface of the filter plate 36, a limiting strip 39 is fixedly installed on the side wall of the mounting plate 38, and a collection box 310 is slidably installed on the mounting plate 38 through the limiting strip 39.

[0029] The specific implementation method is as follows: the coolant used when the milling machine 1 is working flows to the recovery box 2 through the drain pipe. At this time, the filter plate 36 will filter the coolant, and the impurities in the coolant will stay above the filter plate 36. The coolant falls into the recovery box 2, and the drive motor 33 in the mounting cover 32 drives the reciprocating screw 31 to rotate. As the reciprocating screw 31 rotates, the threaded sleeve 34 drives the scraper 35 to move back and forth on the upper surface of the filter plate 36 under the action of the outer surface thread. When moving, the scraper 35 will scrape the impurities to the two ends of the filter plate 36, and then fall into the collection box 310 through the drain trough 37. When the impurities in the collection box 310 reach a certain amount, the collection box 310 is pulled out of the recovery box 2. At this time, the collection box 310 moves on the mounting plate 38 through the limit bar 39.

[0030] The dredging assembly 4 includes a rotating rod 41, one end of which is rotatably connected to the inner wall of the recovery box 2, and the other end of the rotating rod 41 is rotatably connected to the inner wall of the shell cavity of the recovery box 2. The rotating rod 41 and the outer surfaces of the reciprocating screw 31 are fixedly mounted with a toothed sprocket 42, and the toothed sprockets 42 are connected through a toothed chain transmission. A rotating disk 43 is fixedly mounted on the outer surface of the rotating rod 41, and a protrusion 44 is fixedly mounted on the outer surface of the rotating disk 43. A mounting frame 45 is fixedly mounted on the lower surface of the filter plate 36, and a connecting spring 46 is fixedly mounted on the lower surface of the mounting frame 45. A fixing plate 47 is fixedly mounted on one end of the connecting spring 46, and an impact rod 48 is fixedly mounted on the upper surface of the fixing plate 47. One end of the impact rod 48 passes through the interior of the connecting spring 46 and extends to the outside of the upper surface of the mounting frame 45. A top block 49 is fixedly mounted on the lower surface of the fixing plate 47, and the lower surface of the top block 49 is in contact with the outer surface of the rotating disk 43.

[0031] The specific implementation method is as follows: when the reciprocating screw 31 rotates, the rotating rod 41 rotates under the action of the sprocket wheel 42 and the toothed chain. At this time, the rotating rod 41 drives the rotating disk 43 to rotate, so that the protrusion 44 rotates synchronously. With the rotation of the protrusion 44, under the action of the top block 49, the fixed plate 47 drives the impact rod 48 to impact the filter plate 36. Under the action of the connecting spring 46, the impact rod 48 will continuously impact the filter plate 36. The impacted filter plate 36 will vibrate. With the vibration of the filter plate 36, the impurities in the filter hole will be shaken out and then scraped away by the scraper 35.

[0032] Working principle: When the milling machine 1 is working, the coolant used flows to the recovery box 2 through the drain pipe. At this time, the filter plate 36 will filter the coolant, and the impurities in the coolant will stay above the filter plate 36. The coolant falls into the recovery box 2, and the drive motor 33 in the mounting cover 32 drives the reciprocating screw 31 to rotate. As the reciprocating screw 31 rotates, the threaded sleeve 34 drives the scraper 35 to move back and forth on the upper surface of the filter plate 36 under the action of the outer surface thread. When the scraper 35 moves, it will scrape the impurities to the two ends of the filter plate 36, and then fall into the collection box 310 through the drain trough 37. When the impurities in the collection box 310 reach a certain amount, the collection box 310 is removed from the recovery box. The collecting box 310 is pulled out from the box 2. At this time, the collecting box 310 moves on the mounting plate 38 through the limiting bar 39. When the reciprocating screw 31 rotates, the rotating rod 41 will rotate under the action of the sprocket wheel 42 and the toothed chain. At this time, the rotating rod 41 drives the rotating disk 43 to rotate, so that the protrusion 44 rotates synchronously. With the rotation of the protrusion 44, under the action of the top block 49, the fixing plate 47 drives the impact rod 48 to impact the filter plate 36. Under the action of the connecting spring 46, the impact rod 48 will continuously impact the filter plate 36. The impacted filter plate 36 will vibrate. With the vibration of the filter plate 36, the impurities in the filter hole will be shaken out and then scraped away by the scraper 35.
