[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0019] Please refer to Figures 1-4 This utility model discloses a CNC profile saw blade for steel pipes, comprising a saw disc 1 and saw teeth 11. The saw teeth 11 are the main cutting structure of the profile saw blade, and the saw disc 1 is the mounting structure for the saw teeth 11, and also houses other structures. A mounting plate 12 is provided at the bottom of the saw teeth 11, and a mounting slot 14 is provided on the outer side of the saw disc 1. The mounting plate 12 and the mounting slot 14 are slidably connected, meaning the mounting plate 12 is slidably installed into the mounting slot 14, thereby mounting the saw teeth 11 on the outer side of the saw disc 1. A mounting ring 3 is provided inside the saw disc 1. The mounting ring 3 has an installation component 2 inside. Both the mounting ring 3 and the installation component 2 are installation structures. The inner side of the mounting plate 12 and the inner side of the mounting slot 14 are provided with a bayonet 13. The mounting ring 3 is provided with a bolt 31. The bolt 31 and the bayonet 13 are slidably connected. That is, the bolt 31 connects to the bayonet 13, so that the mounting ring 3 is installed inside the saw blade 1. The bolt 31 connects to the bayonet 13 in the mounting plate 12, thereby fixing the saw teeth 11. The bolt 31 connects to the bayonet 13 in the mounting slot 14, thereby fixing the mounting ring 3.
[0020] The mounting component 2 is equipped with a connecting assembly for connecting the saw blade 1 and the mounting ring 3. The connecting assembly includes an annular retaining plate 21. An annular groove 22 is provided on the inner side of the saw blade 1. The annular retaining plate 21 is engaged in the annular groove 22 and rotates in the annular groove 22, thereby installing the mounting component 2 on the inner side of the saw blade 1 and allowing it to rotate. The inner side of the mounting ring 3 is provided with an internal thread 32, and the outer side of the mounting component 2 is provided with an external thread 23. The external thread 23 and the internal thread 32 are threadedly connected. When the mounting ring 3 is installed, the retaining bolt 31 is aligned with the locking slot 13. By rotating the mounting component 2, the locking slot 13 limits the retaining bolt 31, thereby installing the mounting ring 3. When disassembling, only the mounting ring 3 needs to be disassembled, the damaged saw teeth 11 can be removed and replaced, and the device can still be used without replacing the entire saw blade.
[0021] The mounting ring 3 has fixing components on both sides for fixing the mounting part 2. Each fixing component includes a slide groove 33, inside which a slider 44 is slidably connected. A plug 4 is mounted on the slider 44. The mounting part 2 has insertion ports 24 on both sides, allowing the plug 4 to be installed and removed from the insertion ports 24. A threaded opening 34 is located on the outer side of the slide groove 33, inside which a bolt 43 is installed. The bolt 43 is threadedly connected to the threaded opening 34, and a rotating pin 42 is mounted on the bolt 43. The slider 4... 4. A rotating port 41 is provided at the top, and a rotating bolt 42 is locked in the rotating port 41 and rotates in the rotating port 41. After the mounting ring 3 is installed, the insertion port 24 is just aligned with the sliding groove 33. That is, by rotating the bolt 43 on the outside and rotating the rotating bolt 42 in the rotating port 41, the slider 44 slides in the sliding groove 33, and the insertion block 4 is inserted into the insertion port 24, thereby fixing the mounting part 2 and preventing the mounting part 2 from rotating, that is, preventing disassembly and ensuring use. Conversely, disassembly can be performed if the mounting part 2 is not rotated.
[0022] The working principle of this utility model is as follows: the mounting plate 12 is slidably installed into the mounting slot 14, thereby installing the saw teeth 11 on the outside of the saw disc 1. When the mounting ring 3 is installed, the bolt 31 is connected to the bayonet 13, the internal thread 32 is connected to the external thread 23, and the mounting part 2 is rotated, with the bayonet 13 limiting the bolt 31, thereby installing the mounting ring 3. The bolt 31 connects to the bayonet 13 in the mounting plate 12, thereby fixing the saw teeth 11. The bolt 31 connects to the bayonet 13 in the mounting slot 14, thereby fixing the mounting ring 3. Ring 3: After the mounting ring 3 is installed, the insertion port 24 is perfectly aligned with the sliding groove 33. That is, by rotating the bolt 43 on the outside and rotating the rotating pin 42 in the rotating port 41, the slider 44 slides in the sliding groove 33, and the insertion block 4 is inserted into the insertion port 24, thereby fixing the mounting part 2 and preventing it from rotating, i.e., it cannot be disassembled, thus ensuring its use. Conversely, it can be disassembled. When disassembling, only the mounting ring 3 needs to be removed, the damaged saw teeth 11 can be taken out and replaced, and it can still be used without replacing the entire saw blade.
[0023] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
