[0002] Machining center is developed from CNC milling machine. The biggest difference between machining center and CNC milling machine is that machining center has the ability to automatically exchange machining tools. By installing tools of different purposes on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changer in one clamping to achieve multiple machining functions. CNC machining center is a high-efficiency automated machine tool composed of mechanical equipment and CNC system suitable for machining complex parts. CNC machining center is one of the most productive and widely used CNC machine tools in the world.

[0003] A Chinese patent with publication number: CN202222240764.0 discloses a CNC machining center scheme with a dust removal structure, which includes a vertical CNC milling machine, a workbench, a base plate and a dust removal component.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 6As shown, the utility model provides a dust removal type small CNC machining center, including a small CNC machine tool 1 and a tool holder 2. The small CNC machine tool 1 is internally installed with a tool holder 2, where the tool holder 2 is an existing mature technology and can be equipped with different tools to perform mechanical processing on the workpiece; an air inlet hood 3 is installed at the back opening of the small CNC machine tool 1, a filter screen 4 is installed on one side inner wall of the air inlet hood 3, a protective shell 5 is installed on the back of the small CNC machine tool 1, an air duct 6 is connected to the tail end of the air inlet hood 3, an exhaust fan 7 is installed on the outer side wall of the air duct 6, an air outlet duct 8 is installed at the bottom opening of the air duct 6, a dust collecting box 9 is connected to the bottom of the dust collecting box 9, a drawer 10 is connected to the outer side wall of the drawer 10, a connecting block 11 is connected to the outer side wall of the drawer 10, a fixing block 12 is connected to the outer side wall of the dust collecting box 9, and a rotating buckle 13 is connected to the surface of the fixing block 12. The above-mentioned equipment has a corresponding power supply connection for power supply and is uniformly controlled.

[0028] Working principle and process of this utility model:

[0029] The implementation steps are divided into two steps: first, the collected dust is settled; second, the iron filings attached to the filter 4 are cleaned, as follows:

[0030] 1. Initially, during the processing of the workpiece, the exhaust fan 7 is started to guide the dusty air through the air inlet cover 3, the air duct 6 and the air outlet duct 8 to the dust box 9. Then the dust is accumulated in the drawer 10 containing water. The dust blown in is settled by the moisture in the drawer 10. When it is necessary to dump, the rotating buckle 13 is rotated counterclockwise along the connecting block 11 so that the bottom end of the rotating buckle 13 is separated from the fixed block 12, and the drawer 10 is pulled out from one side of the dust box 9, which can facilitate the dumping and cleaning of the dust, effectively improve the efficiency of dust removal, and avoid the phenomenon of dust floating;

[0031] It should be noted that in this process, the exhaust end of the exhaust fan 7 also has a filtering effect, preventing dust and debris from entering the interior of the exhaust fan 7, thereby ensuring the normal use of the exhaust fan 7. In addition, in the process of inducing air, the air duct 6 and the dust box 9 are separated by the air outlet duct 8, reducing the probability of dust backflow.

[0032] 2. Initially, by sliding the cleaning plate 15 up and down along the positioning plate 14, the sliding block 16 is driven to slide along the inner wall of the opening of the positioning plate 14, and at the same time, the sliding block 16 is driven to slide along the guide rod 17, and then the brush at the notch of the cleaning plate 15 cleans the iron filings attached to the filter 4 to prevent the phenomenon of waste chips clogging, thereby improving the quality of dust removal during processing.

[0033] In summary, the settings of "one and two" can improve the efficiency of dust removal during machine tool processing, while avoiding the phenomenon of dust floating easily. In addition, the waste chips attached to the filter screen 4 can be cleaned, further improving the dust removal effect.

[0034] Specifically, the air inlet hood 3 and the air duct 6 are interconnected, and a dust filter is installed at the air outlet of the exhaust fan 7. This structure can reduce the loss of the exhaust fan 7 and prevent dust and waste from being drawn into the interior of the exhaust fan 7. The size of the drawer 10 is matched with the inner wall size of the dust box 9. The inner wall of the drawer 10 is filled with water. The drawer 10 and the dust box 9 form a sliding connection structure. By draining the dust to the drawer 10 filled with water, the dust is easily settled and the phenomenon of dust floating is avoided.

[0035] Furthermore, the rotating buckle 13 is made of stainless steel, and the recess at the bottom of the rotating buckle 13 and the connecting block 11 form a snap-fit ​​structure. During this process, the drawer 10 can be pulled out or installed by connecting or disconnecting the opening at the bottom of the rotating buckle 13 with the connecting block 11.

[0036] Furthermore, positioning plates 14 are installed on the outer walls at both ends of the air inlet hood 3, and a cleaning plate 15 is connected to one side of the positioning plate 14. The cleaning plate 15 is in a U-shaped structure, and brushes are evenly arranged at the recesses of the cleaning plate 15. The cleaning plate 15 with the brush is used to clean the surface of the filter 4 to reduce the adhesion of iron filings and impurities on the filter 4. Sliding blocks 16 are connected to both ends of the recess of the cleaning plate 15. The sliding block 16 is in a T-shaped structure. The cleaning plate 15 slides through the sliding block 16 and the opening on the surface of the positioning plate 14. The sliding block 16 slides along the opening on one side of the positioning plate 14, which can improve the smoothness of the cleaning plate 15 sliding up and down.

[0037] It is worth mentioning that a guide rod 17 is connected through the surface of the sliding block 16, and the upper and lower ends of the guide rod 17 are fixedly mounted on the inner wall of the positioning plate 14. By sliding the sliding block 16 along the guide rod 17 all the time, the cleaning plate 15 is prevented from tilting when sliding up and down.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
