[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figures 1-6 The utility model provides an embodiment: a CNC device for processing metal workpieces, comprising a mounting base 1, two support bases 2 are installed on the rear side of the mounting base 1, and the support base 2 provides an installation position for an operating device 4. A controller 3 is provided on the outside of one of the support bases 2, which is convenient for the operator to operate and monitor at any time during the operation of the equipment. The two support bases 2 are provided with operating devices 4 to provide control for the processing drill 5. The processing drill 5 is installed at the bottom of the operating device 4, and the processing drill 5 processes the workpiece. An operating table 6 is fixedly connected to the top of the mounting base 1, and the operating table 6 provides a stable placement and processing platform for the metal workpiece. A limiting mechanism 7 is provided on the top of the operating table 6, and the limiting mechanism 7 can limit the position of the workpiece during the processing process. The inner cavity of the mounting base 1 is provided with a chip suction mechanism 8, which can suck in and collect chips for easy cleaning. An electrostatic elimination mechanism 9 is provided on one side of the top of the mounting base 1, and the electrostatic elimination mechanism 9 can release ions to neutralize the static electricity on the chips, thereby reducing the adsorption and flying of chips.

[0034] The debris suction mechanism 8 includes a vacuum cleaner 801, which is the core component of the entire debris suction mechanism 8 and can generate a strong suction force. The output end of the vacuum cleaner 801 is fixedly connected to a plurality of debris suction pipes 802, which transfer the suction force generated by the vacuum cleaner 801 to the area where debris is required to be sucked. One end of the debris suction pipe 802 is fixedly connected to a dust collecting hood 803, which can increase the effective area for debris suction and form a centralized collection effect for the surrounding debris. The outer side of the dust collecting hood 803 is fixedly connected to a dust collecting frame 804, and the outer sides of the plurality of dust collecting frames 804 are fixedly connected to the top of the mounting base 1. The dust collecting frame 804 plays a role in stabilizing the dust collecting hood 803 and covering a larger area of ​​the debris suction area, while connecting the debris suction structure to the mounting base 1. The input end of the vacuum cleaner 801 is provided with a collection component, which is used to collect debris.

[0035] Reference Figure 3 and Figure 4 The collection assembly includes a collection frame 805. The bottom of the collection frame 805 is fixedly connected to the inner cavity of the mounting base 1. The top of the collection frame 805 is connected to the vacuum cleaner 801, allowing debris to be smoothly transferred from the vacuum cleaner 801 to the collection box 806. The inner wall of the collection frame 805 is slidably connected to the collection box 806, which provides a centralized storage container for the debris. The outer side of the collection box 806 is provided with a guide assembly, which is used to guide the collection box 806 while sliding on the inner wall of the collection frame 805.

[0036] Reference Figure 4 The guide assembly includes two guide plates 808, the outer sides of which are fixedly connected to the outer sides of the collection box 806. The inner wall of the collection frame 805 is provided with two guide grooves 807, and the outer sides of the guide plates 808 are slidably connected to the inner walls of the guide grooves 807. The guide assembly ensures that the collection box 806 slides accurately and smoothly on the inner wall of the collection frame 805. During the installation and removal of the collection box 806, the guide assembly prevents the collection box 806 from shifting or getting stuck. This makes the installation and removal of the collection box 806 more convenient and smooth.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The front side of the mounting seat 1 is rotatably connected to a door body 809 , and the door body 809 is located on the front side of the mounting seat 1 , which is convenient for cleaning the collection box 806 of the debris suction mechanism 8 .

[0038] Reference Figure 1 , Figure 2 and Figure 5The static elimination mechanism 9 includes a fixed cylinder 901 and an electrostatic column 903. The bottom of the fixed cylinder 901 is mounted on the top side of the mounting base 1. The electrostatic column 903 is a key component for eliminating static electricity, which can release ions to neutralize the static electricity carried by metal debris. A fixed rod 902 is inserted into the inner wall of the fixed cylinder 901. The top of the fixed rod 902 is fixedly connected to the bottom of the electrostatic column 903, making the installation of the electrostatic column 903 relatively simple. The bottom of the electrostatic column 903 is provided with a locking assembly, which is used to lock the electrostatic column 903 during installation.

[0039] Reference Figure 5 The locking assembly includes a locking rod 904, and locking holes 905 are provided on the inner sides of the fixing cylinder 901 and the fixing rod 902. The outer side of the locking rod 904 is inserted into the inner wall of the locking hole 905, making it easy to fix the electrostatic column 903 in the fixing cylinder 901, reducing operation time and improving production efficiency.

[0040] Reference Figure 1 , Figure 2 and Figure 6 The limiting mechanism 7 includes two fixed plates 701, the bottoms of the two fixed plates 701 are fixedly connected to the top two sides of the operating table 6 respectively, and the fixed plates 701 provide stable support for the entire limiting mechanism 7. The internal thread of the fixed plate 701 is connected to a transmission screw 702. By rotating the transmission screw 702, the transmission screw 702 can convert the rotational motion into linear motion when rotating, and the moving distance of the movable plate 703 can be accurately controlled by the pitch of the screw. The operator can accurately adjust the position of the movable plate 703 by rotating the transmission screw 702 according to the size and shape of the workpiece, thereby achieving clamping and limiting of workpieces of different specifications. The opposite ends of the two transmission screws 702 are rotatably connected to the movable plate 703, and one movable plate 703 can move relative to each other, clamping the workpiece on both sides, thereby improving the stability and reliability of the clamping.

[0041] Reference Figure 6 The opposite sides of the two movable plates 703 are fixedly connected with rubber plates 704. The rubber plates 704 have a large friction coefficient. When the movable plates 703 clamp the workpiece, the rubber plates 704 contact the workpiece surface, which can significantly increase the friction force of the clamping force on the workpiece surface and avoid scratching the workpiece.

[0042] Working Principle: First, place the metal workpiece to be machined on the operating table 6. Rotating the drive screw 702 pushes the movable plate 703. The two movable plates 703 move relative to each other, and the workpiece is clamped in place by the rubber plate 704, preventing movement during machining and ensuring machining accuracy. The rubber plate 704 also prevents scratches on the workpiece.

[0043] The controller 3 is then used to set and send processing instructions. After receiving the instructions, the operating device 4 drives the processing drill 5 to perform processing operations on the metal workpiece placed on the operating table 6 to shape the workpiece.

[0044] When cleaning the mounting base 1 and the operating table 6, the large waste materials from processing on the mounting base 1 and the operating table 6 are collected first. The remaining debris is difficult to clean. Then, the electrostatic column 903 is installed by inserting the fixing rod 902 connected to the bottom of the electrostatic column 903 into the fixing tube 901, and then inserting the locking rod 904 into the fixing tube 901 and the locking hole 905 on the fixing rod 902.

[0045] After the electrostatic column 903 is installed, the ions released by the electrostatic column 903 during the cleaning process will neutralize the metal debris with positive static electricity by releasing negative ions. When the debris has negative static electricity, the electrostatic column 903 will release positive ions to neutralize it, thereby reducing the phenomenon of debris being adsorbed and flying due to static electricity. At this time, by starting the vacuum cleaner 801, the vacuum cleaner 801 generates suction after startup, and transmits the suction force to the dust hood 803 and the dust collection frame 804 area through the dust suction pipe 802. After the debris generated by the processing is sucked in, it is transported to the collection frame 805 through the internal channel of the vacuum cleaner 801. The debris falls into the collection box 806 in the collection frame 805. The collection box 806 is easy to extract, making it easier to clean these debris. Both large waste materials and small debris can be properly handled. This can significantly reduce the accumulation of debris in the processing area, prevent debris from causing harm to operators, and reduce the risk of debris entering the equipment and causing equipment failure.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
