[0022] The following will be combined with the drawings of the utility model to the drawings Figure 1 to the drawings Figure 5The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0023] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.
[0024] Example 1
[0025] Please see Figure 1 - Figure 5 As shown, this embodiment provides a low-noise CNC slant turning structure, including a CNC slant turning machine body 1, a noise protection structure 2 provided on the outside of the CNC slant turning machine body 1, and a groove 3 for receiving cutting debris opened in the middle of the machine tool of the CNC slant turning machine body 1.
[0026] The noise protection structure 2 includes a servo motor 21 installed on the left side of the CNC slant car body 1, a worm gear 22 fixedly connected to the output end of the servo motor 21, and a rotating rod 23. The rotating rod 23 passes through the CNC slant car body 1 and is externally fixedly connected to a shield 24, which is made of transparent acrylic sheet.
[0027] This invention takes into account that while the existing technology employs a slant bed design to reduce noise to some extent, it lacks specific noise reduction measures for high-frequency cutting noise between the tool and workpiece, as well as hydraulic and cooling system fluid noise during the cutting process. These noises, combined with chip collision noise, exacerbate the noise pollution problem in the workshop. Therefore, through the design of the noise protection structure 2, when the CNC slant lathe is working, the servo motor 21 is started, driving the worm gear 22 to rotate. The worm wheel 25, which meshes with the worm gear 22, rotates accordingly, causing the rotating rod 23 to drive the shield 24 to rotate 90 degrees to the top surface of the CNC slant lathe body 1, covering the working area. The glass wool boards on both sides of the inner wall of the shield 24 can effectively absorb noise, reduce the impact of noise on the surrounding environment, and create a quiet working environment for the operator. At the same time, the self-locking function between the worm gear 22 and the worm wheel 25 can further lock the position of the shield 24, ensuring that it stably covers the working area and continuously plays a sound insulation role.
[0028] Meanwhile, in terms of chip handling, the groove 3 can collect the chips generated during cutting, and the collection tray 27 is slidably connected in the groove 3, which facilitates the collection and cleaning of chips, keeps the machine tool clean, and reduces the interference of chips on the normal operation of the machine tool.
[0029] Example 2
[0030] like Figure 2 - Figure 5 As shown, the worm gear 22 is externally meshed with a worm wheel 25. The right end of the worm wheel 25 is fixedly connected to the left end of the rotating rod 23. Glass wool boards for absorbing noise are installed on both sides of the inner wall of the shield 24. The shield 24 is made of transparent acrylic sheet material, which not only ensures that the operator can clearly observe the processing process, but also provides support for the glass wool board inside. The porous structure of the glass wool board can effectively absorb noise of different frequencies, blocking and absorbing noise from the source. Meanwhile, the self-locking characteristics of the worm 22 and worm wheel 25 ensure that the shield 24 is firmly covered, preventing displacement due to vibration and other factors, and continuously and stably playing a noise reduction role. A support plate 26 for supporting the shield 24 is installed on the back of the CNC slant lathe body 1. When not in use, the shield 24 is placed on the support plate 26. When in use, the shield 24 is rotated 90 degrees by the rotating rod 23 to cover the entire working area on the top surface of the CNC slant lathe body 1. The self-locking between the worm 22 and worm wheel 25 can further lock the position of the shield 24. A collection tray 27 for collecting debris is slidably connected inside the groove 3.
[0031] It is worth noting that the two functions of noise protection and chip handling work together. The noise protection structure 2 reduces noise interference to operators, improving work comfort and concentration, while convenient chip handling ensures stable operation of the equipment. The two work together to significantly improve the overall performance and practicality of the CNC slant lathe.
[0032] Work steps:
[0033] First, when using the CNC slant lathe body 1, the servo motor 21 is started to drive the worm gear 22 to rotate. The worm gear 22 meshes with the worm wheel 25, which in turn drives the rotating rod 23 to rotate the shield 24 to the top surface of the CNC slant lathe body 1, covering the entire working area. At the same time, the self-locking function between the worm gear 22 and the worm wheel 25 is used to lock the position of the shield 24 to ensure its stability. Then, the CNC slant lathe is started for machining operations. During the cutting process, the high-frequency noise generated by the tool and the workpiece, as well as the fluid noise generated by the hydraulic and cooling systems, are absorbed by the glass wool boards on both sides of the inner wall of the shield 24, thereby reducing the impact of noise on the surrounding environment. The cutting debris falls directly into the groove 3 in the middle of the machine tool. After the machining is completed or the debris accumulates to a certain extent, the debris can be easily removed and cleaned by sliding the collection tray 27 in the groove 3, keeping the machine tool clean and ensuring stable operation of the equipment.
[0034] According to the disclosure and teaching of the above description, the skilled in the art of the present application can also change and modify the above embodiments. Therefore, the present application is not limited to the specific embodiments disclosed and described above, and some modifications and changes of the present application should also fall within the protection scope of the claims of the present application. In addition, although some specific terms are used in the specification, these terms are only for convenience of description and do not constitute any limitation on the present application.
