[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 5 A chip cleaning device for a numerically controlled machine tool comprises a first U-shaped frame 1 and a second U-shaped frame 2. A mounting plate 7 is arranged above the first U-shaped frame 1 and the second U-shaped frame 2. A driving component for driving the mounting plate 7 to move horizontally is arranged on the first U-shaped frame 1 and the second U-shaped frame 2. The driving component comprises two guide slide blocks 3 respectively connected in a sliding manner in the first U-shaped frame 1 and the second U-shaped frame 2. The mounting plate 7 is fixedly connected to the upper ends of the two guide slide blocks 3 by screws, so as to facilitate the installation and removal of the mounting plate 7. The first U-shaped frame 1 is provided with a servo motor mounted on the side wall of the first U-shaped frame 1. The threaded rod 4 driven by the servo motor 5 is rotatably connected to the inner side wall of the other end of the first U-shaped frame 1, so that the threaded rod 4 can rotate stably. The thread of the threaded rod 4 penetrates the relative guide slider 3. The servo motor 5 drives the threaded rod 4 to rotate, and can make the corresponding guide slider 3 drive the mounting plate 7 to move horizontally under the action of its thread meshing. The second U-shaped frame 2 is fixedly connected with a guide rod 6, which slides through the relative guide slider 3. The guide rod 6 can limit the guide slider 3, so that the guide slider 3 can stably slide horizontally in the second U-shaped frame 2;

[0023] A cleaning assembly is detachably mounted on the bottom of the mounting plate 7. The cleaning assembly includes a cleaning brush 8 mounted on the bottom of the mounting plate 7 by screws. The mounting plate 7 drives the cleaning brush 8 to move horizontally, which can push the debris on the CNC machine tool workbench to move and clean it. Two connecting plates 9 are mounted on the bottom of the mounting plate 7 by screws. The two connecting plates 9 are respectively located on the left and right sides of the cleaning brush 8. The height of the connecting plate 9 is less than the height of the cleaning brush 8, so that the connecting plate 9 cannot push the waste chips to move. Electromagnets 10 are embedded at the bottom of the two connecting plates 9. When the electromagnets 10 are energized, they can adsorb the iron filings on the CNC machine tool, which is convenient for collecting and centralizing them.

[0024] The first U-shaped frame 1 and the second U-shaped frame 2 are both detachably connected with a chip storage assembly, which includes a chip storage plate 13 arranged between the first U-shaped frame 1 and the second U-shaped frame 2. The chip storage plate 13 is tilted on one side close to the cleaning assembly, and a chip storage groove 12 is provided on the chip storage plate 13, so that the cleaning brush 8 can push the waste chips along the inclined surface of the chip storage plate 13 into the chip storage groove 12 for collection. A partition plate is provided in the chip storage groove 12, so that the waste chips cleaned by the cleaning brush 8 and the waste chips cleaned by the electromagnet 10 can be stored separately. A vertical plate 14 is provided on the upper end of the chip storage plate 13, and a card slot 11 is provided on the upper end of the first U-shaped frame 1 and the second U-shaped frame 2. Limiting members are provided on the vertical plate 14 and extend into the corresponding card slots 11 respectively.

[0025] The limiting member includes a slide groove 15 opened on the vertical plate 14, and a U-shaped plate 16 extending into the slot 11 is slidably connected in the slide groove 15. A plurality of tension springs are connected between the U-shaped plate 16 and the inner side wall of the slide groove 15. In a natural state, the tension spring can pull the U-shaped plate 16 downward to insert it into the corresponding slot 11, thereby stably fixing the vertical plate 14 between the first U-shaped frame 1 and the second U-shaped frame 2.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] In the utility model, the device is installed on the working table of the CNC machine tool. When the debris of the CNC machine tool needs to be cleaned, the servo motor 5 is started to drive the threaded rod 4 to rotate, and the guide slider 3 can drive the mounting plate 7 to move back and forth horizontally under the action of its thread meshing. In this process, the electromagnet 10 is energized to adsorb and clean the metal waste, and the cleaning brush 8 can push the non-metallic waste to move and clean. The cleaning brush 8 can push the waste along the inclined surface of the chip storage plate 13 to one side of the partition plate in the chip storage groove 12 for collection. When the electromagnet 10 moves above the chip storage groove 12, the electromagnet 10 is powered off, and the metal waste can fall into the chip storage groove 12 on the other side of the partition plate for storage. The mounting plate 7 moves back and forth, so that the electromagnet 10 and the cleaning brush 8 work together to automatically clean the waste, saving human resources.

[0028] By pulling the U-shaped plate 16 upward to remove it from the slot 11 , the chip storage plate 13 can be removed from the first U-shaped frame 1 and the second U-shaped frame 2 , so as to facilitate cleaning of waste chips.
