[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figures 1 to 8 As shown, a machine tool spindle cleaning device includes an upper outer shell 1, a middle outer shell 2 fixedly connected to the bottom of the upper outer shell 1, a lower outer shell 3 fitted to the bottom of the middle outer shell 2, a connecting block 4 fixedly connected to the upper surface of the lower outer shell 3, hinges 5 fixedly connected to the upper surface of the connecting block 4 and the bottom of the upper outer shell 1, an air outlet 6 opened at the bottom of the lower outer shell 3, an axial flow fan 7 fixedly connected to the inner wall of the lower outer shell 3, a filter screen 8 fixedly connected to the upper surface of the lower outer shell 3, the filter screen 8 being conical in shape and located in the middle of the middle outer shell 2, a conical connecting plate 9 fixedly connected to the inner wall of the upper outer shell 1, an air groove 10 opened on the inner wall of the conical connecting plate 9, and a cleaning bracket 11 fixedly connected to the inner wall of the conical connecting plate 9. An air inlet 12 is provided on the surface of the shell 1. A hollow cube 13 is fixedly connected to the surface of the lower shell 3. Slide grooves 14 are provided on both the front and rear sides of the hollow cube 13. A first U-shaped plate 15 is fitted to the inner wall of the slide groove 14. A pressing plate 16 is fixedly connected to the left side of the first U-shaped plate 15. A snap-fit ​​block 17 is fixedly connected to the left side of the pressing plate 16. A groove 18 is provided on the left side of the lower shell 3. A fixing post 19 is fixedly connected to the bottom of the upper shell 1. The surface of the fixing post 19 is fitted to the inner wall of the groove 18. A snap-fit ​​slot 20 is provided on the right side of the fixing post 19. The inner wall of the snap-fit ​​slot 20 is fitted to the surface of the snap-fit ​​block 17. Springs 21 are fixedly connected to the inner wall of the first U-shaped plate 15 and the left side of the hollow cube 13.

[0029] The cleaning bracket 11 includes a rotating shaft 111, a bearing 112, a fan blade 113, and a cleaning brush 114. The surface of the rotating shaft 111 is fixedly connected to the inner ring of the bearing 112, the outer ring of the bearing 112 is fixedly connected to the inner wall of the conical connecting plate 9, the surface of the rotating shaft 111 is fixedly connected to the inner wall of the fan blade 113, the upper surface of the rotating shaft 111 is fixedly connected to the bottom of the cleaning brush 114, and sealing rings 22 are fitted on both the upper and lower sides of the bearing 112. The inner wall of the sealing ring 22 is fixedly connected to the surface of the rotating shaft 111. The rotating shaft 111 is located in the middle of the upper outer shell 1, and the fan blade 113 is located below the conical connecting plate 9.

[0030] It should be noted that when the axial flow fan 7 is turned on, the air inside the upper outer casing 1 is forced through the middle outer casing 2 into the lower outer casing 3 by the axial flow fan 7. The air inside the lower outer casing 3 is discharged through the air outlet 6, and the air outside the upper outer casing 1 enters the upper outer casing 1 through the air inlet 12 or the opening at the top of the upper outer casing 1.

[0031] When the air inside the upper outer casing 1 enters the lower outer casing 3 through the middle outer casing 2, the airflow drives the fan blades 113 to rotate, and the rotating fan blades 113 cause the cleaning brush to rotate. At this time, the rotating cleaning brush cleans the inner cavity of the spindle, and the filter screen 8 filters the cleaned-down cutting chips. The filtered cutting chips accumulate inside the middle outer casing 2.

[0032] The first U-shaped plate 15 can only move left and right on the hollow block 13 through the slide groove 14. When the snap-fit ​​block 17 is inserted into the slot 20, the spring 21 prevents the snap-fit ​​block 17 from automatically moving out of the slot 20. Through the cooperation of the slot 20 and the snap-fit ​​block 17, the middle outer shell 2 is fixed on the lower outer shell 3. When the snap-fit ​​block 17 is separated from the slot 20, the middle outer shell 2 can rotate around the hinge 5.

[0033] like Figures 1 to 9 As shown, a slip ring 23 is fitted to the surface of the upper outer shell 1. A limit block 24 is fixedly connected to the inner wall of the slip ring 23. The surface of the limit block 24 is fitted to the inner wall of the air inlet 12. A second U-shaped plate 25 is fixedly connected to the left side of the slip ring 23. A bolt 26 is fitted to the inner wall of the second U-shaped plate 25. A retaining ring 27 is fixedly connected to the surface of the bolt 26. The upper surface of the retaining ring 27 is fitted to the bottom of the second U-shaped plate 25. A threaded cylinder 28 is threadedly connected to the surface of the bolt 26. The bottom of the threaded cylinder 28 is fixedly connected to the upper surface of the upper outer shell 1.

[0034] It should be noted that, through the cooperation of slip ring 23, second U-shaped plate 25, bolt 26, retaining ring 27 and threaded cylinder 28, the user can adjust the distance between limit block 24 and middle outer shell 2 by rotating bolt 26. At the same time, when the machine tool spindle cleaning device cleans the inner cavity of the spindle, the limit block 24 can restrict the position of the spindle end in the upper outer shell 1, thereby preventing the cleaning brush 114 from rotating too slowly due to excessive contact between the cleaning brush 114 and the inner cavity of the spindle.

[0035] The working principle of this utility model is as follows: First, adjust the distance between the limiting block 24 and the inner shell 2 according to the depth of the spindle cavity. During adjustment, by rotating the bolt 26, the limiting block 24 moves up or down with the cooperation of the second U-shaped plate 25, the retaining ring 27, the bolt 26 and the threaded cylinder 28. When the limiting block 24 moves to the appropriate position, the self-locking property between the bolt 26 and the threaded cylinder 28 makes the position of the limiting block 24 impossible to change.

[0036] When the spindle cavity needs to be cleaned, first insert the cleaning brush into the spindle cavity, and use the limiting block 24 to ensure that the cleaning brush 114 does not make too tight contact with the spindle cavity. Then, turn on the axial flow fan 7 to generate airflow from top to bottom in the upper outer shell 1, middle outer shell 2 and lower outer shell 3. At this time, the airflow drives the fan blade 113 to rotate, and the rotating fan blade 113 causes the cleaning brush to rotate. Then, the rotating cleaning brush cleans the spindle cavity. At the same time, the filter screen 8 filters the cleaning chips, and the filtered chips accumulate in the middle outer shell 2.

[0037] When it is necessary to clean the cutting chips collected inside the inner casing 2, first press the pressing plate 16 to separate the snap block 17 on the pressing plate 16 from the slot 20. Then, by rotating the upper casing 1, the cutting chips on the filter screen 8 can be exposed.

[0038] After the shavings on the filter screen 8 are cleaned, the upper outer shell 1 is rotated so that the bottom of the middle outer shell 2 contacts the upper surface of the lower outer shell 3, and the locking block 17 is inserted into the slot 20. At this time, the spring 21 prevents the locking block 17 from automatically moving out of the slot 20, and the middle outer shell 2 is fixed to the lower outer shell 3 by the cooperation of the slot 20 and the locking block 17.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
