Description

Technical Field

[0001] This invention relates to the field of vertical CNC machine tool technology, and more specifically to a vertical CNC machine tool with a chip splash guard. Background Technology

[0002] As automated machine tools equipped with program control systems, CNC machine tools have been widely used in the field of machining since the world's first vertical CNC milling machine was invented in 1952. Utilizing digital signals to precisely control the movement of the machine tool and its machining process, they possess significant advantages such as high machining accuracy, high production efficiency, stable product quality, and a high degree of automation. They can perform complex surface machining that is difficult or impossible for ordinary machine tools. Their application areas have gradually expanded from the initial aerospace industry to numerous manufacturing sectors such as automobiles, shipbuilding, and civilian machinery, playing a crucial role in promoting the development of the manufacturing industry.

[0003] During processing, a large amount of debris is generated, and this debris is extremely hot when it is first cut out. On the one hand, the high-speed flying debris can easily cause injury to operators on site. If it hits the operator's skin, eyes, or other parts, it may lead to serious consequences, greatly affecting operator safety, reducing operational safety, and hindering the processing of related workpieces. On the other hand, it is usually difficult to install protective covers on existing equipment later. Replacing it with a machine with a protective cover would be too costly, placing a significant economic burden on the company. In addition, most existing protective covers can only block the frontal metal chips and cannot effectively control the rebound position of the metal chips, causing the metal chips to often accumulate inside the machine tool or on the guide rails. This is not only inconvenient to clean but may also affect the normal operation and service life of the machine tool, increasing equipment maintenance costs and downtime. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a vertical CNC machine tool with a debris splash guard.

[0010] Preferably, a drive motor is fixedly connected to the outer wall of the L-shaped fixing frame, and the output of the drive motor is detachably connected to the processing head.

[0011] Preferably, the impurity extraction mechanism further includes an exhaust fan installed on the outer wall of the extraction hood, a storage box fixedly connected to the outer wall of the rotating cylinder, the exhaust end of the exhaust fan being fixedly connected to the inside of the storage box, a rotating ring being contacted at the top of the rotating cylinder, a limit ring being fixedly connected to the bottom of the rotating ring, an elastic rubber pad being fixedly connected to the inner circumferential wall of the rotating ring, and the output end of the drive motor rotating through the elastic rubber pad.

[0015] 3. This machine tool is equipped with an impurity extraction mechanism. During processing, the fourth motor drives the gears to rotate, causing the rotating drum to rotate. Simultaneously, the exhaust fan is activated, drawing debris and impurities into the rotating drum through the extraction hood and extraction slot, and then transporting them to the storage box for storage. Compared to traditional machine tools, there is no need for frequent manual cleaning of iron filings accumulated inside the machine tool and on the slide rails, greatly reducing the amount of cleaning work, facilitating machine tool maintenance, and maintaining a clean working environment.

The water pumping end of the water pump 9 is connected to the inside of the storage cavity.

[0029] The working principle of this invention is as follows: When the vertical CNC machine tool with a chip splash guard is used for processing, the first motor 51 is started first. The output end of the first motor 51 drives the first threaded rod 53 to rotate, so that the first threaded sleeve 56 with the threaded sleeve on it moves linearly. At the same time, the first sliding block 55 slides and engages at the top of the first limiting member 54 to ensure that the placement table 2 moves smoothly, thereby adjusting the position of the workpiece placed on the placement table 2.

[0030] Next, if it is necessary to adjust the horizontal position of the processing head, the second motor 61 is started. The second motor 61 drives the second threaded rod 63 to rotate, and the second threaded sleeve 68 moves linearly along the second threaded rod 63. The second sliding block 65 slides and engages with the outer wall of the second limiting member 64, so that the connecting plate 67 moves horizontally. If it is necessary to adjust the vertical position of the processing head, the third motor 612 is started. The third motor 612 drives the third threaded rod 613 to rotate, and the third threaded sleeve 614 moves linearly along the third threaded rod 613. The third sliding block 69 slides and engages with the outer wall of the third limiting member 610. The L-shaped fixing frame 611 drives the processing head to move vertically. Through these two steps, the processing head is precisely positioned in three-dimensional space.

[0031] After positioning is completed, the drive motor 615 starts, and its output drives the machining head to rotate, performing cutting, drilling and other machining operations on the workpiece placed on the placement table 2. During the machining process, the fourth motor 710 starts, and its output drives the gear 711 to rotate, which meshes with the gear ring 712 to make the rotating cylinder 71 rotate. At the same time, the rotating ring 76 contacts the top of the rotating cylinder 71 through the limiting ring 77, which can ensure that the movement of the machining head is not obstructed, and also seals the rotating cylinder 71 to prevent impurities from flying out. At the same time, the exhaust fan 74 is started, and the chips and impurities generated during machining are sucked into the rotating cylinder 71 through the extraction cover 73 and the extraction groove 72, and then transported to the storage box 75 for storage.

[0032] To prevent the processing head from overheating, the water pump 9 is started to extract the cooling liquid from the storage chamber and deliver it to the processing head through the water outlet pipe 8. After the cooling liquid takes away the heat from the processing head, it and impurities are continuously pumped into the storage box 75 for storage.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
