An inclined slope is arranged on one side of the collecting groove close to the hollow rotating shaft.

[0013] Further, a plurality of notches are equidistantly opened on the slope. Each hollow suction cup is located in the corresponding notch, and inclined arc-shaped scraping plates are fixedly connected to the inner walls on both sides of the notch.

Specific embodiments

[0030] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0031] Embodiment 1: Refer to Figures 1-6, A vertical machining center equipped with a chip cleaning mechanism, including a machining center 2, a machining table 1 is arranged in the machining center 2, and a plurality of T-shaped grooves are equidistantly arranged on the machining table 1. U-shaped frames 5 are arranged on both sides of the machining table 1, and fixing plates 6 are fixedly connected between the U-shaped frames 5 and the machining table 1. A moving mechanism is arranged between the two U-shaped frames 5, and two mounting boxes 7 are arranged on the moving mechanism. A hollow rotating shaft 9 is rotatably connected between the two mounting boxes 7, and a rotating mechanism is arranged at one end of the hollow rotating shaft 9. A plurality of hollow suction discs 13 are fixedly connected to the outer wall of the hollow rotating shaft 9 at equal intervals, and a plurality of rectangular frames 20 are arranged at equal intervals inside the hollow suction discs 13. Two magnetic plates 26 are slidably connected in a staggered manner on the inner walls of the rectangular frames 20, and the N poles and S poles of the two magnetic plates 26 are arranged in a staggered manner. One end of each of the two magnetic plates 26 is fixedly connected to a slide plate 24, and a first connecting spring 25 is fixedly connected between the two slide plates 24. When it is necessary to clean each T-shaped groove on the machining table 1, the moving mechanism is started to make the hollow rotating shaft 9 drive a plurality of hollow suction discs 13 to insert into the corresponding T-shaped grooves and move. At the same time, the rotating mechanism makes the hollow rotating shaft 9 rotate, so that each hollow suction disc 13 rotates in the corresponding T-shaped groove. The surfaces with the largest surface areas of the magnetic plates 26 in the rectangular frames 20 all face the inner walls of the hollow suction discs 13. Thus, when the hollow suction discs 13 rotate, the waste chips and impurities in the T-shaped grooves can be adsorbed onto the surfaces of the hollow suction discs 13, thereby completing the cleaning work of each T-shaped groove.

[0032] As a further scheme in the present invention, the moving mechanism includes two threaded rods 3. The two threaded rods 3 are both rotatably connected between the two U-shaped frames 5, and transmission wheels 10 are arranged at one end of each of the two threaded rods 3. A transmission belt 8 is sleeved on the outer walls of the two transmission wheels 10. A first driving motor 4 is arranged at the other end of one of the threaded rods 3, and threaded sliders 11 are threadedly slidably connected to the outer walls of the two threaded rods 3. The two mounting boxes 7 are fixedly connected to the corresponding threaded sliders 11. The first driving motor 4 makes the threaded rod 3 connected thereto rotate, and under the cooperation of the transmission wheels 10 and the transmission belt 8, the other threaded rod 3 rotates synchronously, enabling the hollow rotating shaft 9 between the two mounting boxes 7 to move.

[0033] As a further scheme in the present invention, the rotating mechanism includes a transmission shaft 16 and a second bevel gear 19. The second bevel gear 19 is fixedly connected to the outer wall at one end of the hollow rotating shaft 9. The transmission shaft 16 is rotatably connected to the top of one of the mounting boxes 7, and a second driving motor 15 is arranged at the top end of the transmission shaft 16. A first bevel gear 14 is fixedly connected to the bottom end of the transmission shaft 16, and the first bevel gear 14 meshes with the second bevel gear 19. The second driving motor 15 makes the first bevel gear 14 on the transmission shaft 16 rotate. Since the first bevel gear 14 meshes with the second bevel gear 19 on the outer wall of the hollow rotating shaft 9, the hollow rotating shaft 9 can be rotated.

[0034] As a further solution in the present invention, a rotating column 21 is fixedly connected to the outer wall of one side of each rectangular frame 20, and the rotating column 21 is rotatably connected to the outer wall of the hollow rotating shaft 9. One end of the rotating column 21 is fixedly connected to a gear 23.

[0035] As a further solution in the present invention, a plurality of electric push rods 12 are equidistantly arranged on the outer wall of one side of the hollow rotating shaft 9, and a plurality of sliding rods 18 are slidably connected to the outer wall of the other side of the hollow rotating shaft 9 at equal intervals. A rack 22 is fixedly connected between the telescopic end of each electric push rod 12 and the corresponding sliding rod 18, and the rack 22 meshes with the corresponding gear 23. A limiting disc 17 is fixedly connected to the outer wall of the other end of the sliding rod 18. When it is necessary to separate the impurities and waste chips adsorbed on the hollow suction disc 13, each electric push rod 12 is activated to move the plurality of racks 22. Since the rack 22 meshes with the gear 23 on the corresponding rotating column 21, the corresponding rectangular frame 20 can be rotated by 90 degrees through the rotating column 21. When the rectangular frame 20 rotates, one end of the magnetic plate 26 on its inner wall will contact the inner wall of the hollow suction disc 13. Under the action of the extrusion force, the two magnetic plates 26 slide until the side edge of the magnetic plate 26 contacts the inner wall of the hollow suction disc 13, so that the contact area between the magnetic plate 26 and the inner wall of the hollow suction disc 13 is reduced, resulting in a reduction in the adsorption area, thus facilitating the cleaning of the adsorbed waste chips and impurities from the hollow suction disc 13.

[0036] Working principle: When it is necessary to clean each T-shaped groove on the processing table 1, the driving motor 1 makes the threaded rod 3 connected to it rotate. And with the cooperation of the transmission wheel 10 and the transmission belt 8, the other threaded rod 3 rotates synchronously, enabling the hollow rotating shaft 9 between the two mounting boxes 7 to move. Thus, the hollow rotating shaft 9 drives multiple hollow suction cups 13 to insert into the corresponding T-shaped grooves and move. At the same time, the driving motor 2 makes the bevel gear 1 on the transmission shaft 16 rotate. Because the bevel gear 1 meshes with the bevel gear 2 on the outer wall of the hollow rotating shaft 9, the hollow rotating shaft 9 can be rotated, so that each hollow suction cup 13 rotates in the corresponding T-shaped groove. The surfaces of the magnetic plates 26 with the largest surface area in the rectangular frame 20 all face the inner wall of the hollow suction cup 13. Thus, when the hollow suction cup 13 rotates, the waste chips and impurities in the T-shaped groove can be adsorbed onto the surface of the hollow suction cup 13, thereby completing the cleaning work of each T-shaped groove. When it is necessary to make the impurities and waste chips adsorbed on the hollow suction cup 13 fall off, each electric push rod 12 starts, making multiple racks 22 move. Because the rack 22 meshes with the gear 23 on the corresponding rotating column 21, the corresponding rectangular frame 20 can be rotated by 90 degrees through the rotating column 21. When the rectangular frame 20 rotates, one end of the magnetic plate 26 on its inner wall will contact the inner wall of the hollow suction cup 13. Under the action of the extrusion force, the two magnetic plates 26 slide until the side of the magnetic plate 26 contacts the inner wall of the hollow suction cup 13, so that the contact area between the magnetic plate 26 and the inner wall of the hollow suction cup 13 is reduced, resulting in a reduction in the adsorption area, thus facilitating the cleaning of the adsorbed waste chips and impurities from the hollow suction cup 13.

[0037] Embodiment 2: Refer to Figures 7-8 , a vertical machining center provided with a chip cleaning mechanism. Compared with Embodiment 1, on the basis of Embodiment 1, connecting plates 28 are fixedly connected to the outer walls of the two mounting boxes 7, and a collecting groove 27 is fixedly connected between the outer walls on the opposite sides of the two connecting plates 28. An inclined slope 29 is arranged on one side of the collecting groove 27 close to the hollow rotating shaft 9. During the cleaning process of each T-shaped groove of the processing table 1, the hollow suction cup 13 drives the magnetic plates 26 in the multiple rectangular frames 20 to rotate in the corresponding T-shaped grooves.

[0038] As a further solution in the present invention, a plurality of notches are equidistantly formed on the slope 29. Each hollow suction cup 13 is located in a corresponding notch, and inclined arc-shaped scraping plates 30 are fixedly connected to the inner walls on both sides of the notch. The arc-shaped scraping plates 30 are in contact with the outer wall of the hollow suction cup 13. When the rectangular frame 20 passes by the inclined arc-shaped scraping plates 30, the corresponding electric push rod 12 is activated, causing the rack 22 connected to the telescopic end of the electric push rod 12 to move. Through cooperation with the gear 23 on the rotating column 21, the rectangular frame 20 is rotated by ninety degrees. When the rectangular frame 20 rotates, one end of the magnetic plate 26 on its inner wall will contact the inner wall of the hollow suction cup 13. Under the action of the extrusion force, the two magnetic plates 26 slide until the side edges of the magnetic plates 26 contact the inner wall of the hollow suction cup 13, thereby reducing the contact area between the magnetic plates 26 and the inner wall of the hollow suction cup 13, resulting in a reduction in the adsorption area. Thus, the waste chips and impurities adsorbed at this position of the hollow suction cup 13 can be quickly scraped off by the arc-shaped scraping plates 30, automatically completing the cleaning of the hollow suction cup 13.

[0039] Working principle: During the cleaning process of each T-shaped groove of the processing table 1, the hollow suction cup 13 will drive the magnetic plates 26 in the plurality of rectangular frames 20 to rotate in the corresponding T-shaped grooves. When the rectangular frame 20 passes by the inclined arc-shaped scraping plates 30, the corresponding electric push rod 12 is activated, causing the rack 22 connected to the telescopic end of the electric push rod 12 to move. Through cooperation with the gear 23 on the rotating column 21, the rectangular frame 20 is rotated by ninety degrees. When the rectangular frame 20 rotates, one end of the magnetic plate 26 on its inner wall will contact the inner wall of the hollow suction cup 13. Under the action of the extrusion force, the two magnetic plates 26 slide until the side edges of the magnetic plates 26 contact the inner wall of the hollow suction cup 13, thereby reducing the contact area between the magnetic plates 26 and the inner wall of the hollow suction cup 13, resulting in a reduction in the adsorption area. Thus, the waste chips and impurities adsorbed at this position of the hollow suction cup 13 can be quickly scraped off by the arc-shaped scraping plates 30, automatically completing the cleaning of the hollow suction cup 13.

[0040] Example 3: Refer to Figure 9, A vertical machining center equipped with a chip cleaning mechanism. Compared with Embodiment 2, on the basis of Embodiment 2, a through hole 35 is opened at the bottom of the collection tank 27, and a baffle 34 is slidably connected to the outer wall of the through hole 35. Mounting plates 33 are fixedly connected to both outer walls of the collection tank 27. A second permanent magnet 32 is fixedly connected to the outer wall of the baffle 34, and a second connecting spring 36 is fixedly connected between the second permanent magnet 32 and the mounting plate 33. A first permanent magnet 31 is arranged on the other side of the collection tank 27, and the first permanent magnet 31 is fixedly connected to the U-shaped frame 5. The first permanent magnet 31 attracts the second permanent magnet 32. Under the elastic force of multiple second connecting springs 36, the baffle 34 is in close contact with the inner wall of the through hole 35, thereby sealing the through hole 35. The impurities and chips in the collection tank 27 still remain therein. When cleaning each T-shaped groove in the machining table 1, the hollow rotating shaft 9 will move from one side of the machining table 1 to the other side. During this process, the first permanent magnet 31 on the baffle 34 will gradually approach the second permanent magnet 32. After each T-shaped groove in the hollow suction discs 13 is disengaged, due to the attraction between the first permanent magnet 31 and the second permanent magnet 32, under the action of the suction force, the baffle 34 in the through hole 35 will slide, so that the through hole 35 is no longer closed, and the garbage and impurities in the collection tank 27 can fall out, eliminating the need for manual cleaning of the collection tank 27.

The impurities and chips in the collection tank 27 still remain therein.
