All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1:

[0027] Please refer to Figure 1 and Figure 4 - Figure 5 as shown, a chip self-cleaning mechanism for a numerical control machine tool includes:

[0028] A machine tool 1, and a blanking channel 11 is fixedly installed at the top of the machine tool 1 through a grooving.

[0029] A cleaning assembly 2 is arranged on both sides of the top of the machine tool 1. The cleaning assembly 2 includes a support plate 21 symmetrically installed on both sides of the top of the machine tool 1. Two turntables 23 are movably installed on one side of the support plate 21. A lifting bar 25 is movably connected to one side of the support plate 21. A cleaning rod 27 is connected between the lifting bars 25.

[0030] The collecting component 3 is arranged on one side of the feeding channel 11. The collecting component 3 includes a collecting box 31 movably installed outside the feeding channel 11. Locking holes 32 are opened on both sides of the feeding channel 11. U-shaped plates 33 are symmetrically installed on both sides of the collecting box 31. A locking rod 35 is movably installed inside the U-shaped plate 33.

[0031] Specifically, two support rods 22 are connected between the support plate 21 and the machine tool 1, and two turntables 23 are movably installed on the side of the support plate 21 close to the machine tool 1 through bearings. The two turntables 23 are symmetrically arranged, and a swing rod 24 is fixedly installed on one side of the two turntables 23. A lifting bar 25 is movably connected to one side of the support plate 21, and the swing rod 24 is hinged to the lifting bar 25 on the side close to the lifting bar 25. A servo motor 26 is installed on the side of the support plate 21 away from the turntable 23 through a fixed seat, and the output end of the servo motor 26 is connected to the shaft of the turntable 23 through a coupling. A cleaning rod 27 is fixedly connected between the lifting bars 25, and a brush 28 is arranged on the cleaning rod 27 close to the machine tool 1.

[0032] As can be seen from the above, by arranging lifting bars 25 on both sides of the machine tool 1, and using the lifting bars 25 to drive the cleaning rod 27 to move up and down to perform a cleaning action, the debris on the outside of the material discharge channel 11 can be swept into the material discharge channel 11, and the debris on the machine tool 1 will not be swept to the outside of the machine tool 1 during the reciprocating motion.

[0033] During specific use, the servo motor 26 is started to drive the turntable 23 to rotate. The turntable 23 drives the cleaning rod 27 to move downward and approach the inside of the machine tool 1 through the swing rod 24, so as to sweep the debris on the machine tool 1 into the discharge channel 11. Then the cleaning rod 27 will move to the outside of the machine tool 1 and make an upward movement. During this process, the cleaning rod 27 will not contact the surface of the machine tool 1, and will not sweep the debris to the outside of the machine tool 1. Such repeated operations can accurately sweep the debris into the discharge channel 11.

[0034] Embodiment 2:

[0035] See also Figure 1 - Figure 3 As shown, a collecting box 31 is movably installed on the outside of the feeding channel 11, and the collecting box 31 is slidably fitted with the outer wall of the feeding channel 11. Locking holes 32 are symmetrically opened on both sides of the feeding channel 11, and U-shaped plates 33 are symmetrically installed on both sides of the collecting box 31. The U-shaped plates 33 are correspondingly arranged with the locking holes 32.

[0036] Specifically, a baffle 34 is fixedly installed inside the U-shaped plate 33. A locking rod 35 is movably installed between the baffle 34 and the U-shaped plate 33 through an opening. The locking rod 35 penetrates into the inside of the collection box 31. The locking rod 35 extends into the locking hole 32. The locking rod 35 is in sliding fit with the inner wall of the locking hole 32. A reset plate 36 is fixedly installed on the outer side of the locking rod 35. Two reset springs 37 are connected between the reset plate 36 and the inner wall of the U-shaped plate 33. The two reset springs 37 are symmetrically arranged on both sides of the locking rod 35.

[0037] As can be seen from the above, a collection box 31 is arranged at the bottom of the blanking channel 11 to collect debris for subsequent processing. At the same time, the disassembly and assembly of the collection box 31 are realized through the cooperation of the locking rod 35 and the locking hole 32, ensuring stable installation and quick disassembly, and making the operation more convenient.

[0038] During specific use, first pull the locking rod 35 to both sides to make the locking rod 35 away from the locking hole 32. At this time, the collection box 31 can be removed. When installing, also first pull the locking rod 35, place the collection box 31 outside the blanking channel 11, and then release the locking rod 35. The locking rod 35 will extend into the locking hole 32 under the action of the reset spring 37 to complete the installation.
