Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a high-precision numerical control machine tool without polishing. Background Art

[0002] A high-precision CNC machine tool is a CNC machine tool that can achieve high-precision surface processing without the need for polishing operations during the processing. Usually, in the traditional processing process, polishing is required after the processing is completed to obtain a smooth and fine surface. However, the high-precision CNC machine tool that does not require polishing uses advanced processing technology and precise control systems. It can achieve the required surface accuracy during the processing process, thereby eliminating the polishing step, improving processing efficiency and reducing costs. This type of CNC machine tool is usually used for processing workpieces with high surface accuracy requirements, such as aerospace, automobile manufacturing, mold manufacturing and other fields.

[0003] At present, the existing high-precision CNC machine tools (such as patent number: CN216758944U) disclose a high-precision CNC machine tool, which relates to the technical field of CNC machine tools, including a machine tool body and a CNC box, the CNC box is installed on the upper surface of one end of the machine tool body, and a power box is fixedly installed on the upper surface of the other end of the machine tool body. An operation area is arranged on the side opposite to the CNC box and the power box, a driving motor is installed inside the power box, a motor shaft is installed at the output end of the driving motor, an articulated seat is fixedly installed at the top of the power box, and a rotating shaft is arranged through the inside of the articulated seat. The utility model, by arranging an articulated seat, a rotating shaft and an installation frame, can quickly open the insect-proof net when the user needs to regularly inspect the driving motor. Since no bolts are used for fixing, there is no need to use tools such as wrenches to disassemble and assemble the bolts, and there is no phenomenon of bolt thread slippage, thereby reducing the difficulty of disassembly and assembly for users and facilitating disassembly and assembly. By arranging a torsion spring, the installation frame can have the effect of automatically popping out.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] When processing on CNC machine tools, cutting tools are usually used to process the workpiece. These cutting tools will remove material and form debris when they come into contact with the workpiece. Since the debris is often very small, it may adhere to the inside of the machine tool. The debris may be widely distributed and have strong adhesion, making it difficult to clean up, especially for some narrow and hard-to-reach areas. The cleaning work is more time-consuming and labor-intensive. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] In view of the deficiencies in the prior art, the utility model provides a high-precision CNC machine tool that does not require polishing, which solves the technical problem that when processing on a CNC machine tool, cutting tools are usually used to process the workpiece.

The debris may be widely distributed and have strong adhesion, making it difficult to clean, especially for some narrow and hard-to-reach areas, where the cleaning work is more time-consuming and labor-intensive.

[0008] (II) Technical solution

[0011] Preferably, the cleaning brush is located between the two moving blocks, and the left and right ends of the two cleaning brushes are fixedly connected to the two corresponding moving blocks.

[0016] (III) Beneficial effects

[0017] 1. Through the control panel, the control panel sends a control program to drive the sprocket to rotate. Since the sprocket is meshed with the synchronous chain, the two sprockets drive the short rod to rotate synchronously. At this time, the two threaded rods will also rotate synchronously with the rotation of the short rod. Since the two moving blocks do not rotate, the two moving blocks will drive the cleaning brush to move to the right. When the cleaning brush moves, it will clean up the small debris attached to the upper surface of the base. When the cleaning brush moves to the edge of the base, the cleaning brush will squeeze the cover. At this time, the spring is compressed, the cover moves to the right, and the metal debris will be cleaned into the collection frame by the cleaning brush. The cleaning brush can clean the debris on the surface of the base, avoiding the problem of inconvenience in cleaning caused by the debris being located in a narrow position inside the main body of the device, thereby improving the efficiency of cleaning work.

[0018] 2. When the cleaning brush returns to its original position, the originally compressed spring rebounds, causing the cover to rebound to the upper surface of the collection frame. At this time, the cover covers the collection frame, preventing the debris in the collection frame from vibrating when the main body of the device is running and causing the debris to fly.

[0026] The embodiment of the present application provides a high-precision CNC machine tool without polishing, which effectively solves the technical problem that when machining on a CNC machine tool, a cutting tool is usually used to machine a workpiece. When these cutting tools come into contact with the workpiece, they will remove material and form debris. Since the debris is often very small, it may adhere to the inside of the machine tool. The debris may be widely distributed and have strong adhesion, making it difficult to clean up, especially for some narrow and hard-to-reach areas. The cleaning work is more time-consuming and labor-intensive. Through the control panel, the control panel sends a control program to drive the sprocket to rotate. Since the sprocket is engaged with the synchronous chain, the two The sprocket drives the short rod to rotate synchronously, and the two threaded rods will also rotate synchronously with the rotation of the short rod. Since the two moving blocks do not rotate, the two moving blocks will drive the cleaning brush to move to the right, and the cleaning brush will clean the fine debris attached to the upper surface of the base when it moves. When the cleaning brush moves to the edge of the base, the cleaning brush will squeeze the cover plate. At this time, the spring is compressed, the cover plate moves to the right, and the metal debris will be cleaned into the collection frame by the cleaning brush. The cleaning brush can clean the debris on the surface of the base, avoiding the problem of inconvenience in cleaning caused by the debris being located in a narrow position inside the main body of the device, thereby improving the efficiency of the cleaning work.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that when machining on a CNC machine tool, a cutting tool is usually used to machine the workpiece. When these cutting tools come into contact with the workpiece, they will remove materials and form debris. Since the debris is often very small, it may adhere to the inside of the machine tool. The debris may be widely distributed and have strong adhesion, making it difficult to clean up, especially for some narrow and difficult-to-reach parts, the cleaning work is more time-consuming and labor-intensive. The overall idea is as follows:

[0029] In view of the problems existing in the prior art, the utility model provides a high-precision CNC machine tool without polishing, including a device body 1, a control panel 3 is arranged on the surface of the device body 1, and the high-precision CNC machine tool without polishing is also provided with a debris cleaning mechanism, including a base 2, a fixed frame 4, a cleaning brush 11, a collecting frame 15, a cover plate 16 and a fixed frame 17, the base 2 is located inside the device body 1, and the lower surface of the base 2 is fixedly connected to the inner wall of the device body 1, the lower surface of the fixed frame 4 is fixedly connected to the upper surface of the base 2, and a synchronous chain 6 is arranged inside the fixed frame 4, the left and right ends of the synchronous chain 6 are meshed and connected with sprockets 7, the two sprockets 7 are fixedly connected with short rods 12, the left surfaces of the two short rods 12 are rotatably connected to the inner wall of the fixed frame 4, and the right surface of the fixed frame 4 is penetrated with holes 5, the right surfaces of the two short rods 12 are rotatably connected to the inner wall of the fixed frame 4 through the holes 5, and the fixed frame 4 Two threaded rods 13 corresponding to the position of the sprocket 7 are arranged at the right end position, and the left surfaces of the two threaded rods 13 are fixedly connected to the right surfaces of the corresponding short rods 12, and the right surfaces of the two threaded rods 13 are rotatably connected with the inner wall of the device body 1, and the upper surface of the base 2 is movably connected with two moving blocks 8 corresponding to the position of the threaded rods 13, and the right surfaces of the two moving blocks 8 are penetrated with thread grooves 10, and each moving block 8 is threadedly sleeved with the corresponding threaded rod 13 through the thread groove 10. Through the control panel 3, the control panel 3 sends a control program to drive the sprocket 7 to rotate. Since the sprocket 7 is meshed with the synchronous chain 6, the two sprockets 7 drive the short rod 12 to rotate synchronously. At this time, the two threaded rods 13 will also rotate synchronously with the rotation of the short rod 12. Since the two moving blocks 8 do not rotate, the two moving blocks 8 will drive the cleaning brush 11 to move to the right, and the cleaning brush 11 will clean up the fine debris attached to the upper surface of the base 2 when moving.

[0030] The cleaning brush 11 is located between the two moving blocks 8, and the left and right ends of the two cleaning brushes 11 are fixedly connected to the two corresponding moving blocks 8. A groove 14 is provided on the upper surface of the base 2, and the collecting frame 15 is located inside the groove 14. The collecting frame 15 is fixedly connected to the inner wall of the base 2, and the lower surface of the fixed frame 17 is fixedly connected to the upper surface of the base 2, and the fixed frame 17 is movably connected to the cover plate 16, and the cover plate 16 is located at the upper end position of the collecting frame 15. When the cleaning brush 11 moves to the edge of the base 2, the cleaning brush 11 will squeeze the cover plate 16. At this time, the spring 19 is compressed, the cover plate 16 moves to the right, and the metal debris will be cleaned into the collecting frame 15 by the cleaning brush 11. The cleaning brush 11 can clean the debris on the surface of the base 2, avoiding the problem of inconvenience in cleaning caused by the debris being located in a narrow position inside the device body 1, thereby improving the cleaning work efficiency.

[0031] Two grooves 218 are formed through the right surface of the cover plate 16, and the cover plate 16 is movably connected with telescopic rods 9 through the two grooves 218. The right surfaces of the two telescopic rods 9 are fixedly connected to the inner wall of the fixed frame 217, the left surfaces of the two telescopic rods 9 are fixedly connected to the fixing columns 20, and the left surfaces of the two fixing columns 20 are fixedly connected to the springs 19. The left surfaces of the two springs 19 are fixedly connected to the inner wall of the cover plate 16. When the cleaning brush 11 returns to its original position, the originally compressed spring 19 rebounds, so that the cover plate 16 rebounds to the upper surface of the collection frame 15 again. At this time, the cover plate 16 covers the collection frame 15, thereby avoiding the problem of debris in the collection frame 15 vibrating and causing debris to fly when the device main body 1 is running.

[0032] Working principle:

[0033] First, through the control panel 3, the control panel 3 sends out a control program to drive the sprocket 7 to rotate. Since the sprocket 7 is meshed with the synchronous chain 6, the two sprockets 7 drive the short rod 12 to rotate synchronously. At this time, the two threaded rods 13 will also rotate synchronously with the rotation of the short rod 12. Since the two moving blocks 8 do not rotate, the two moving blocks 8 will drive the cleaning brush 11 to move to the right. When the cleaning brush 11 moves, it will clean up the small debris attached to the upper surface of the base 2. When the cleaning brush 11 moves to the edge of the base 2, the cleaning brush 11 will squeeze the cover plate 16. At this time, the spring 19 is compressed. The cover 16 moves to the right, and the metal debris will be cleaned into the collection frame 15 by the cleaning brush 11. The cleaning brush 11 can clean the debris on the surface of the base 2, avoiding the problem of debris being located in a narrow position inside the device body 1, which makes cleaning inconvenient, and improves the cleaning efficiency. When the cleaning brush 11 returns to its original position, the originally compressed spring 19 rebounds, causing the cover 16 to rebound to the upper surface of the collection frame 15 again. At this time, the cover 16 covers the collection frame 15, avoiding the problem of debris in the collection frame 15 being vibrated and causing debris to fly when the device body 1 is running.

[0034] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
