The head can be easily disassembled by rotating a knob. A protective shell is raised by a motor.

[0004] While existing technologies can intercept the waste chips generated during milling, thus facilitating their cleaning and enhancing the device's practicality, they still require manual cleaning of the chips on the top surface. Additionally, some chips adhere to the inner wall of the casing, making cleaning inconvenient.

[0005] Therefore, we propose a closed-loop CNC machining center to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a closed CNC machining center to solve the problem mentioned in the background art that the machining center still requires manual cleaning of the debris on the top surface, and some debris will also adhere to the inner wall of the shell, making cleaning inconvenient.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a closed CNC machining center, including an outer shell, with machining components for workpiece machining arranged inside the outer shell, and a chip removal groove opened on the rear side of the outer shell. A motor is fixedly connected to the upper surface of the outer shell, and a rotating shaft is fixedly connected to the output end of the motor. A striking mechanism is provided at the lower end of the rotating shaft. The striking mechanism strikes the outer shell by moving the striking plate it contains. At the same time, when the striking mechanism is running, the nozzles arranged inside the outer shell can clean the waste chips on the worktable over a wide area.

[0008] Furthermore, the striking mechanism includes a turntable, which is fixedly connected to the lower end of the rotating shaft. A fixing rod is fixedly connected to the lower surface side of the turntable, and a linkage rod is nested on the outer side of the fixing rod. A limit rod is fixedly connected to the side of the linkage rod, and the limit rod is nested on the side of the outer shell. A fixing plate is fixedly connected to the lower surface of the side of the limit rod, and a striking plate is fixedly connected to the outer side of the fixing plate.

[0009] Furthermore, the fixed rod forms a sliding structure with the inside of the linkage rod through the turntable, and two sets of limiting rods are symmetrically arranged about the center point of the linkage rod, and the limiting rods form a sliding structure with the outer shell through the linkage rod.

[0010] Furthermore, the striking plate is positioned facing the outer casing, and five sets of striking plates are evenly distributed vertically about the fixing rod.

[0011] Furthermore, racks are fixedly connected to the inner sides of the two sets of fixing plates, an air supply box is fixedly connected to the outer side of the outer shell, an air supply pipe is nested and connected through the inner side of the air supply box, and the other end of the air supply pipe is nested and connected to the outer shell. Gears are fixedly connected to the outer side of the air supply pipe.

[0012] Furthermore, the gear and rack mesh with each other, and the air supply pipe forms a rotating structure with the outer casing through the gear.

[0013] Furthermore, the nozzle is disposed below the air supply pipe, and two sets of air supply pipes are symmetrically arranged about the front and rear of the outer casing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The outer shell is located on the outside of the processing component. When the processing component is processing the workpiece, the outer shell can shield the flying debris generated during the processing, thereby reducing the phenomenon of flying debris scattering everywhere and making subsequent cleaning inconvenient.

[0016] 2. After the workpiece is processed, start the motor. The motor drives the rotating shaft to rotate, which in turn drives the turntable to rotate. At this time, the fixed rod on the lower surface of the turntable will slide along the inside of the linkage rod. Under the resistance of the fixed rod, the linkage rod will drive the limit rod to move. The limit rod will then drive the fixed plate to move, which will cause the striking plate to strike the outer shell, causing the outer shell to vibrate. This will reduce the possibility of flying debris adhering to the inner wall of the outer shell, making it difficult to clean later.

[0017] 3. During the movement, the limiting rod will move along the outer shell. The outer shell limits the limiting rod, thereby making the fixing plate more stable in driving the striking plate to strike, improving the stability of the vibration of the outer shell.

[0018] 4. During the movement of the limit rod, it drives the rack to reciprocate synchronously. The rack drives the gear meshing with it to rotate. At this time, the air supply pipe will rotate under the drive of the gear. The air supply pipe will synchronously drive the nozzle to swing. Air is supplied to the interior of the air supply pipe through the air supply box. The air is discharged from the nozzle to the outside, thereby blowing dust from the work surface in a wide range, reducing the possibility of waste sticking to the work surface. Under the action of wind, the dust can be discharged outward along the dust discharge groove opened on the outside of the outer shell, eliminating the need for manual cleaning by staff, saving time and effort.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1 , Figure 2 and Figure 3 The technical solution shown is provided by this utility model as follows: A closed CNC machining center, which discloses an outer shell 1. The outer shell 1 can prevent the flying debris from scattering everywhere and making subsequent cleaning inconvenient. The outer shell 1 is equipped with a machining component 2 for machining workpieces, and a chip removal groove 4 is opened on the rear side of the outer shell 1. The outer shell 1 is located outside the machining component 2. When the machining component 2 is machining the workpiece, the outer shell 1 can block the flying debris generated during the machining process, thereby reducing the flying debris from scattering everywhere and making subsequent cleaning inconvenient.

[0028] Example 2: Figure 2 , Figure 3 , Figure 4 and Figure 5 The technical solution shown is provided by this utility model as follows: A closed CNC machining center discloses a striking mechanism, which causes the outer shell 1 to vibrate, thereby reducing the phenomenon of waste sticking to the outer shell 1: A motor 5 is fixedly connected to the upper surface side of the outer shell 1, and a rotating shaft 9 is fixedly connected to the output end of the motor 5. A striking mechanism is provided at the lower end of the rotating shaft 9. The striking mechanism strikes the outer shell 1 by moving the striking plate 15 included therein. The striking mechanism includes a turntable 10, which is fixedly connected to the lower end of the rotating shaft 9. A fixing rod 11 is fixedly connected to the lower surface side of the turntable 10. A linkage rod 12 is nested on the outer side of the rod 11. A limiting rod 13 is fixedly connected to the side of the linkage rod 12, and the limiting rod 13 is nested on the side of the outer shell 1. A fixing plate 14 is fixedly connected to the lower side of the limiting rod 13, and a striking plate 15 is fixedly connected to the outer side of the fixing plate 14. The fixing rod 11 forms a sliding structure with the linkage rod 12 through the turntable 10. Two sets of limiting rods 13 are symmetrically arranged about the center point of the linkage rod 12, and the limiting rods 13 form a sliding structure with the outer shell 1 through the linkage rod 12. The striking plate 15 is arranged facing the outer shell 1, and five sets of striking plates 15 are equally spaced vertically about the fixing rod 11.

[0029] After the workpiece is processed, the motor 5 is started, and the motor 5 drives the rotating shaft 9 to rotate, which in turn drives the turntable 10 to rotate. At this time, the fixed rod 11 set on the lower surface of the turntable 10 will slide along the inside of the linkage rod 12. Under the action of the fixed rod 11, the linkage rod 12 will drive the limiting rod 13 to move. At this time, the limiting rod 13 will drive the fixed plate 14 to move, so that the striking plate 15 will strike the outer shell 1, causing the outer shell 1 to vibrate. This reduces the possibility of flying debris adhering to the inner wall of the outer shell 1, which is not conducive to subsequent cleaning. During the movement, the limiting rod 13 will move along the outer shell 1. The outer shell 1 limits the limiting rod 13, so that the fixed plate 14 can more stably drive the striking plate 15 to strike, improving the vibration stability of the outer shell 1.

[0030] Example 3: Figure 4 , Figure 5 and Figure 6 The technical solution shown is provided by the present utility model as follows: A closed CNC machining center, which discloses a nozzle 8. The nozzle 8 can swing by the drive of a striking mechanism, thereby achieving large-area dust removal. When the striking mechanism is running, the nozzle 8 set inside the outer shell 1 can clean the waste on the worktable over a large area. The inner sides of the two sets of fixed plates 14 are fixedly connected to racks 16. The outer side of the outer shell 1 is fixedly connected to an air supply box 7. An air supply pipe 6 is nested and connected through the inner side of the air supply box 7. The other end of the air supply pipe 6 is nested and connected to the outer shell 1. A gear 3 is fixedly connected to the outer side of the air supply pipe 6. The gear 3 and the rack 16 mesh with each other. The air supply pipe 6 forms a rotating structure with the outer shell 1 through the gear 3. The nozzle 8 is set through the lower part of the air supply pipe 6. Two sets of air supply pipes 6 are symmetrically arranged about the front and back of the outer shell 1.

[0031] During the movement of the limit rod 13, it will drive the rack 16 to reciprocate synchronously. The rack 16 will drive the gear 3 meshing with it to rotate. At this time, the air supply pipe 6 will rotate under the drive of the gear 3. The air supply pipe 6 will synchronously drive the nozzle 8 to swing. Air is supplied to the interior of the air supply pipe 6 through the air supply box 7. The gas is discharged outward from the nozzle 8, thereby blowing dust over a wide area of ​​the work surface, reducing the possibility of waste sticking to the work surface. Under the action of wind, the dust can be discharged outward along the chip discharge groove 4 opened on the outside of the outer shell 1, without the need for manual cleaning by the staff, saving time and effort.
