Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal device for a numerically controlled machine tool. Background Art

[0002] CNC machine tools are short for digitally controlled machine tools, which are automated machine tools equipped with a program control system. Since CNC machine tools generate a lot of dust and iron filings when cutting metal sheets, many dust removal devices dedicated to CNC machine tools have been developed on the market.

[0003] A Chinese patent with publication number CN218427172U discloses a dust removal device for a CNC machine tool, comprising a base, a support column welded in the middle above the base, a vacuum cleaner installed on the left side below the support column, and a collection frame for adsorbing and collecting sucked-in iron filings is arranged in the middle of the support column, a door panel is connected to the lower right side of the collection frame, and an auxiliary mechanism is arranged below the movable shaft to help guide the iron filings inside the collection frame; the auxiliary mechanism comprises a transmission gear installed on the outer side of the front and rear ends of the movable shaft, a rack plate is meshed on the outer side below the two transmission gears, a shielding cloth is screwed to the upper left end of the rack plate, and a vortex spring is connected to the end of the shielding cloth, and a shaft is fixed to the end of the vortex spring.

[0004] The utility model can effectively classify and collect dust and iron filings through the electromagnet collection frame, and is also convenient for recycling iron filings, thereby increasing the overall practicality. However, when the dust removal device is in use, it is not convenient to install or disassemble the dust collection hose due to the fixed angle position of the dust collection hood. Therefore, although the flying dust can be collected and cleaned when the CNC machine tool is working to prevent the flying dust from polluting the working environment, some dust cannot be captured by the dust collection hood and will fall into various corners of the machine tool, making it inconvenient to clean, thereby affecting the cleaning effect of the CNC machine tool.

[0005] In view of this, we propose a dust removal device for CNC machine tools. Utility Model Content

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1 - Figure 5 As shown in the figure, this embodiment provides a dust removal device for a numerical control machine tool, including a dust removal box body 1 and a dust suction hood 2. A storage cavity 3 and a dust removal cavity 4 are arranged inside the dust removal box body 1. A height adjustment component is arranged on one side of the dust removal box body 1, and an angle adjustment component for adjusting the angle of the dust suction hood 2 is arranged above the height.

[0026] An air outlet hose 5 and an air inlet hose 6 communicating with the dust removal cavity 4 are arranged inside the storage cavity 3. The upper end of the dust suction hood 2 is communicated with an installation pipe 7. The upper end outside of the installation pipe 7 is rotatably connected with a threaded joint 8. An external thread 9 adapted to the threaded joint 8 is arranged outside the air inlet end of the air inlet hose 6.

[0027] Pipe placement grooves 10 are symmetrically opened at the upper end of the storage cavity 3. Positioning rings 11 are fixedly sleeved on the outer walls of the air inlet end of the air inlet hose 6 and the air outlet end of the air outlet hose 5. Positioning grooves 12 adapted to the positioning rings 11 are symmetrically opened on the upper surface of the dust removal box body 1. Installation grooves for installing magnetic attraction rings 13 are opened on the lower surfaces of the two positioning rings 11. Horseshoe-shaped iron sheets 14 magnetically connected to the magnetic attraction rings 13 are fixedly connected to the inner walls of the two positioning grooves 12. A plurality of pipe winding rods 15 for winding the air outlet hose 5 and the air inlet hose 6 are fixedly connected to the inner wall of the storage cavity 3.

[0028] The above working principle: When in use, the intake end of the intake hose 6 can be rotationally connected to the installation pipe 7 through the threaded joint 8 to be connected and turned on. The height and angle of the dust suction hood 2 can be adjusted through the height adjustment component and the angle adjustment component, so as to facilitate the collection and cleaning of the dust generated during the operation of the CNC machine tool, and ensure the collection and cleaning effect of the flying dust. When the CNC machine tool stops working, the threaded joint 8 can be rotated to remove the intake hose 6 from the dust suction hood 2, so that the dust deposited on the CNC machine tool can be sucked and cleaned by holding the intake hose 6. At the same time, the outlet hose 5 can also be taken out of the storage cavity 3 to spray and clean the angles of the CNC machine tool that are not easy to clean, thus avoiding cleaning dead corners, ensuring the cleaning effect of the CNC machine tool, and the intake hose 6 and the outlet hose 5 can be installed in the positioning groove 12 through the cooperation of the positioning ring 11, the magnetic attraction ring 13 and the horseshoe-shaped iron sheet 14, and the intake hose 6 and the outlet hose 5 are stored in the storage cavity 3 through the arranged pipe winding rod 15, which is convenient for the storage and transportation of the CNC machine tool.

[0029] In order to ensure the dust removal effect of the CNC machine tool, a fan 16 is fixedly installed on the inner wall of the top end of the storage cavity 3. The intake end of the fan 16 is communicated with the inside of the dust removal cavity 4 through a connecting pipe 17. The intake end of the outlet hose 5 is communicated with the outlet end of the fan 16. Two U-shaped positioning rods 18 are fixedly connected to the inner walls on both sides of the dust removal cavity 4. A filter plate 19 and an activated carbon plate 20 are installed in the dust removal cavity 4 through the U-shaped positioning rods 18. The filter plate 19 is arranged below the activated carbon plate 20. The connecting pipe 17 is arranged above the activated carbon plate 20. The intake hose 6 is arranged below the filter plate 19. When in use, the fan 16 is started. Through the cooperation of the intake hose 6 and the dust suction hood 2, the air and dust at the CNC machine tool are sucked into the dust removal cavity 4, and under the filtration of the filter plate 19 and the activated carbon plate, the dust impurities are blocked, so that the clean air is discharged to the outside of the dust removal box body 1 through the outlet hose 5, thus ensuring the dust removal effect of the CNC machine tool.

[0030] Considering the need to absorb the dust generated during the machining of numerically controlled machine tools at different heights, the height adjustment assembly includes a control box 21, which is fixedly connected to the outer wall of the dust removal box body 1. A positioning rack 22 is fixedly connected to the rear end of the inner wall of the control box 21. Sliding grooves 24 for the sliding of support blocks 23 are provided on both inner walls of the control box 21. A reset groove for the movement of a positioning tooth block 26 is provided on the rear surface of the support block 23. A reset spring 25 is fixedly connected to the inner wall of the reset groove, and the other end of the reset spring 25 is fixedly connected to the front surface of the positioning tooth block 26. The positioning tooth block 26 meshes with the positioning rack 22. A pull rod 27 is fixedly connected to the front surface of the positioning tooth block 26. The other end of the pull rod 27 penetrates the outer wall of the support block 23 and is fixedly connected to a handle. A support rod 28 is fixedly connected to the upper surface of the support block 23. During use, the pull rod 27 can be pulled to drive the positioning tooth block 26 to disengage from the positioning rack 22 and compress the reset spring 25. Then, the support block 23 can be pushed up or down to adjust the height of the angle adjustment assembly and the dust suction hood 2 arranged above the support rod 28. After the height adjustment is completed, the pull rod 27 is released, and the positioning tooth block 26 can be reset under the elastic force of the reset spring 25 and mesh with the positioning rack 22 to complete the stabilization of the position of the support block 23 after the height adjustment. Thus, the dust generated during the machining of numerically controlled machine tools at different heights can be absorbed by adjusting the height of the dust suction hood 2, making the dust removal device highly practical.

[0031] To facilitate the adjustment of the angle of the dust suction hood 2 to enhance the dust removal effect on the numerically controlled machine tool, the angle adjustment assembly includes a rotating seat 29, which is fixedly installed on the upper surface of the support rod 28. A connecting rod 30 is rotatably connected to the upper surface of the rotating seat 29 through a damping rotating shaft. The other end of the connecting rod 30 is fixedly connected to a U-shaped control rod 31. Both ends of the U-shaped control rod 31 are respectively rotatably connected to the outer walls on both sides of the dust suction hood 2 through damping rotating shafts. During use, the angle of the dust suction hood 2 can be adjusted through the damping rotating shafts arranged at the U-shaped control rod 31. By changing the position of the dust suction port of the dust suction hood 2, the dust attached to the horizontal and side surfaces of the numerically controlled machine tool can be removed, ensuring the dust removal effect on the numerically controlled machine tool. And when the dust removal device is no longer in use, the connecting rod 30 can be rotated through the damping rotating shaft at the rotating seat 29, so as to move the U-shaped control rod 31 and the dust suction hood 2 directly above the dust removal box body 1, reducing the occupied space and facilitating storage.

[0032] During operation, it is necessary to facilitate the removal of metal debris contained in the dust, so the interior of the dust removal chamber 4 is connected to a mounting block 32 through a plurality of mounting rods 33, and an electromagnet 34 corresponding to the air intake duct is fixedly mounted on the outer wall of the mounting block 32. When the dust at the CNC machine tool enters the dust removal chamber 4 through the air intake hose 6, the electromagnet 34 is energized to adsorb and separate the metal debris in the dust. When the work is completed, the electromagnet 34 can be energized, and then the adsorbed debris can be processed, so as to facilitate the recycling of the metal debris.

[0033] In addition, it is necessary to facilitate the collection of dust filtered by the filter plate 19, so the inner bottom end of the dust removal chamber 4 is slidably connected with a collection drawer 35, and the outer wall of the dust removal box 1 is provided with a pick-up and placement groove compatible with the collection drawer 35, the filter plate 19 and the activated carbon plate 20. Universal wheels are fixedly installed at the four corners of the bottom of the dust removal box 1. When in use, the dust filtered by the filter plate 19 can be collected through the set collection drawer 35, and the set pick-up and placement groove can be used to facilitate the pick-up and placement of the filter plate 19 and the activated carbon plate 20, thereby facilitating the replacement and cleaning of the filter plate 19 and the activated carbon plate 20. The set universal wheels facilitate the movement of the dust removal box 1, thereby facilitating the adjustment of the position of the dust removal box 1 when the CNC machine tool is dusted.
