[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] A high-precision multi-axis machining device for machining precision hardware parts, such as Figures 1-5As shown, the machine includes a housing 6. Both ends of the bottom of the housing 6 are fixed to the base 1 by brackets 2. Inside the housing 6, a mounting plate 8 is connected by a connecting shaft 21. A chuck 16 is installed at one end of the mounting plate 8. The chuck 16 is one of a three-jaw chuck, a four-jaw chuck, or a five-jaw chuck. A multi-axis tool holder 4 is also connected inside the housing 6. In actual use, by fixing the hardware parts to the chuck 16, the hardware parts can then be machined in multiple axes by the tools on the multi-axis tool holder 4.

[0028] like Figure 1 and Figure 5 As shown, a slag discharge port 3 is provided at the bottom of the casing 6. A slag guide plate 9 is provided inside the casing 6. The slag guide plate 9 is inclined, and one end of the slag guide plate 9 passes through the slag discharge port 3 and extends to the outside of the casing 6. Several moving blocks 24 are installed on both sides of the bottom of the slag guide plate 9. The moving blocks 24 are connected to the base 1 through a guide mechanism. The guide mechanism includes two pairs of second fixed blocks 19 fixed to the top of the base 1. A guide rod 23 is installed between each pair of second fixed blocks 19. The moving blocks 24 located on the same side are slidably sleeved on the side of the corresponding guide rod 23. The moving blocks 24 can be limited by the guide rod 23, so that the slag guide plate 9 can remain stable.

[0029] like Figure 1 and Figure 5 As shown, a strip mounting plate 25 is installed between two moving blocks 24. A rotating shaft 26 is rotatably connected to the adjacent surfaces of the two supports 2. A U-shaped rod 11 is connected between the two rotating shafts 26. A connecting rod 10 is rotatably connected to the side of the U-shaped rod 11. The other end of the connecting rod 10 is fixed to the side of the strip mounting plate 25 through a hinge seat. A first drive motor 22 is connected to the side of one of the rotating shafts 26. After processing, the operator can control the first drive motor 22 to work. The first drive motor 22 can drive the rotating shaft 26 to rotate. When the rotating shaft 26 rotates, it can drive the U-shaped rod 11 to rotate. In turn, the U-shaped rod 11 drives the connecting rod 10 to swing. When the connecting rod 10 swings, it will drive the slag guide plate 9 to reciprocate, and discharge the impurities falling on the slag guide plate 9 out of the casing 6 without leaving any residue.

[0030] like Figure 2 and Figure 3As shown, two first fixing blocks 15 are symmetrically installed on the side of the mounting plate 8. Hollow shafts 5 are rotatably connected to the side of each first fixing block 15. An arc-shaped tube 18 is installed between the hollow shafts 5. Several nozzles 20 are installed on the side of the arc-shaped tube 18. One of the hollow shafts 5 is connected to the air blowing mechanism. The air blowing mechanism includes a fixing frame 12 fixed on the other side of the mounting plate 8. An air pump 13 is installed on one side of the fixing frame 12. An exhaust pipe 14 is installed at the air outlet of the air pump 13. One end of the exhaust pipe 14 is connected to the end of one of the hollow shafts 5 through a rotating joint. During use, the air pump 13 can deliver external air into the exhaust pipe 14, and then deliver it into the arc-shaped tube 18 through the exhaust pipe 14, and finally spray it out through the nozzles 20. The air is sprayed onto the surface of the chuck 16 to clean the impurities left on the chuck 16 during the processing.

[0031] like Figure 2 and Figure 4 As shown, a second drive motor 27 is mounted on the side of the fixing frame 12. The second drive motor 27 is connected to a second gear 28 via a drive shaft, and a first gear 17 is connected to the end of one of the hollow shafts 5. The first gear 17 meshes with the second gear 28. In use, the second drive motor 27 can drive the second gear 28 to rotate, and the second gear 28 and the first gear 17 work together to drive the hollow shaft 5 to rotate, thereby causing the arc-shaped tube 18 to rotate along the hollow shaft 5. When the arc-shaped tube 18 rotates, it will drive the nozzle 20 to move, so that the nozzle 20 always faces the surface of the chuck 16, blowing off the impurities on the surface of the chuck 16 and cleaning it thoroughly.

[0032] It should be noted that there is a gap between the end of the nozzle 20 and the edge of the chuck 16, so that the nozzle 20 will not collide with the surface of the chuck 16 when it moves with the arc tube 18.

[0033] like Figure 1 As shown, a hatch 7 is slidably connected to the side of the housing 6. The hatch 7 covers the opening of the housing 6. When in use, the operator can close the hatch 7 so that the debris will not fly to the outside of the housing 6 during the processing.

[0034] In use, the operator fixes the hardware to be processed onto the chuck 16, and then processes the workpiece using the cutting tools on the multi-axis tool holder 4. After processing, the operator removes the hardware and then controls the second drive motor 27 and the air pump 13 to work. The second drive motor 27 drives the second gear 28 to rotate, which in turn drives the hollow shaft 5 to rotate through the cooperation of the first gear 17 and the second gear 28, causing the arc-shaped tube 18 to rotate along the hollow shaft 5. At the same time, the air pump 13 can deliver external air into the arc-shaped tube 18 through the exhaust pipe 14, and finally through the nozzle. The 20 spray is directed onto the surface of the chuck 16, cleaning the debris adhering to the surface of the chuck 16 without hindering subsequent hardware processing. After the debris on the chuck 16 is cleaned, the debris will fall onto the surface of the guide plate 9 under gravity. Then, the operator controls the first drive motor 22 to work, which drives the rotating shaft 26 to rotate. The rotating shaft 26 drives the U-shaped rod 11 to rotate, and the U-shaped rod 11 drives the connecting rod 10 to swing back and forth. In turn, under the action of the connecting rod 10, the guide plate 9 will move back and forth, expelling the debris on the guide plate 9 from the machine housing 6, making cleaning convenient.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
