[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1 to 6 The present invention will describe the above technical solution in detail through the following embodiments:
[0027] An automated cutting device for mechanical design and manufacturing includes: a chassis 1; a fixed frame 2 is fixedly connected to one side of the top of the chassis 1, a lifting block 3 is provided inside the fixed frame 2, a fixed cover 4 is fixedly connected to one side of the lifting block 3, a saw blade 5 is provided inside the fixed cover 4, a first rotating shaft 6 is fixedly connected to the center of the saw blade 5, a protective cover 7 is provided on the outside of the fixed cover 4, one side of the protective cover 7 is rotatably connected to the first rotating shaft 6, a steel pipe body 8 is provided at the bottom of the saw blade 5; a protective mechanism 9 is provided on one side of the protective cover 7 to control the opening and closing of the protective cover 7; both ends of the steel pipe body 8 are provided with a linkage mechanism 10 to clamp and fix the steel pipe body 8, a control box is fixedly connected to the side of the chassis 1 away from the fixed frame 2, the user fixes the steel pipe body 8 to the chassis 1 through the linkage mechanism 10, and while the user controls the saw blade 5 to move downward, the protective cover 7 automatically rotates and opens around the first rotating shaft 6, thereby cutting the steel pipe body 8.
[0028] like Figure 2 and Figure 4As shown, the protective mechanism 9 includes: a second rotating shaft 11 fixedly connected to one side of the protective cover 7; a connecting rod 12 rotatably connected to the outer surface of the second rotating shaft 11; a third rotating shaft 13 rotatably connected to the end of the connecting rod 12 away from the second rotating shaft 11; fixed blocks 14 rotatably connected to both ends of the third rotating shaft 13; and fixed blocks 14 fixedly connected to the fixed frame 2. A screw 15 is threadedly connected to the inside of the lifting block 3; the bottom end of the screw 15 rotatably connects to the housing 1; the top end of the screw 15 penetrates the fixed frame 2 and extends to the first motor 16; the first motor 16 is fixedly connected to the fixed frame 2; the screw 15 is fixedly connected to the output end of the first motor 16; one end of the first rotating shaft 6 penetrates the fixed cover 4 and extends to the second motor 17; the second motor 17 is fixedly connected to the fixed cover 4; and the first rotating shaft 6 is fixedly connected to the output end of the second motor 17. The first motor 17 is then started. 6 and the second motor 17. The output end of the second motor 17 drives the saw blade 5 to rotate through the first rotating shaft 6. The output end of the first motor 16 drives the screw 15 to rotate. While the screw 15 rotates, it drives the lifting block 3, causing the lifting block 3 to move vertically downward inside the fixed frame 2. As the lifting block 3 descends, it drives the fixed cover 4. The fixed cover 4 drives the saw blade 5 and the protective cover 7 through the first rotating shaft 6. While the protective cover 7 moves downward, the connecting rod 12 pulls the second rotating shaft 11 through the cooperation of the third rotating shaft 13 and the fixed block 14. The second rotating shaft 11 pulls the protective cover 7, causing the protective cover 7 to slowly open with the first rotating shaft 6 as the center, so that the bottom of the saw blade 5 cuts the steel pipe body 8. When the fixed cover 4 rises, the protective cover 7 closes, thereby blocking the saw blade 5 and effectively preventing personnel from touching the saw blade 5.
[0029] like Figure 4 As shown, both sides of the screw 15 are provided with slide rods 18. The two ends of the slide rods 18 are fixedly connected to the housing 1 and the fixed frame 2 respectively. The lifting block 3 is slidably connected to the slide rods 18, which can limit the lifting block 3, so that the lifting block 3 can move flexibly vertically inside the fixed frame 2.
[0030] like Figure 5 and Figure 6As shown, the linkage mechanism 10 includes: two clamping blocks 19 at each end of the steel pipe body 8; a movable block 20 fixedly connected to the bottom of each clamping block 19; each movable block 20 slidably connected to the housing 1; a fourth rotating shaft 21 fixedly connected to the bottom of each movable block 20; a linkage rod 22 rotatably connected to the outer surface of each fourth rotating shaft 21; a fifth rotating shaft 23 rotatably connected to the end of each linkage rod 22 away from the fourth rotating shaft 21; two fifth rotating shafts 23 fixedly fixed to the top sides of the rotating plate 24; a sixth rotating shaft 25 fixedly connected to the center of the rotating plate 24; both ends of the sixth rotating shaft 25 rotatably connected to the housing 1; a worm gear 26 fixedly provided at the bottom of the rotating plate 24; each worm gear 26 fixedly connected to the sixth rotating shaft 25; a worm 27 meshing on one side of each worm gear 26; both worms 27 fixedly fixed to the outer surface of the transmission shaft 28; one end of the transmission shaft 28 rotating with the housing 1. The transmission shaft 28 is connected to the housing 1 at one end and extends to the third motor 29 at the other end. The third motor 29 is fixedly connected to the housing 1. The transmission shaft 28 is fixedly connected to the output end of the third motor 29. When the third motor 29 is started, the output end of the third motor 29 drives the transmission shaft 28. The transmission shaft 28 drives two worm gears 27 at the same time. While the worm gears 27 rotate, they drive the worm wheels 26 respectively. The worm wheels 26 drive the sixth rotating shaft 25 respectively. While the sixth rotating shaft 25 rotates, it drives the rotating plate 24. While the rotating plate 24 rotates, it drives the fifth rotating shaft 23 to rotate. While the fifth rotating shaft 23 rotates, it pulls one end of the linkage rod 22, so that the other end of the linkage rod 22 pulls the fourth rotating shaft 21. The fourth rotating shaft 21 drives the moving block 20, so that the moving block 20 drives the clamping block 19 to move towards the steel pipe body 8, thereby clamping and fixing both ends of the steel pipe body 8.
[0031] like Figure 3 As shown, sliding grooves 30 are provided on both sides of the movable block 20. Limiting slide bars 31 are fixedly connected to the chassis 1 near the sliding grooves 30. The movable block 20 is slidably connected to the limiting slide bars 31 through the sliding grooves 30, which can limit the movable block 20 and make the movable block 20 slide flexibly inside the chassis 1.
[0032] like Figure 6 As shown, damping pads 32 are fixedly connected to the side of the clamping block 19 closest to the steel pipe body 8, which improves the stability of the clamping block 19 clamping the steel pipe body 8.
[0033] like Figure 1 As shown, the bottom four corners of the chassis 1 are all fixedly connected with casters 33 with braking function, which makes it convenient for users to move and fix the device.
[0034] Working principle: The user places the steel pipe body 8 onto the machine casing 1, and then starts the third motor 29. The output end of the third motor 29 drives the transmission shaft 28, which in turn drives two worm gears 27. As the worm gears 27 rotate, they drive the worm wheels 26, which in turn drive the sixth rotating shaft 25. As the sixth rotating shaft 25 rotates, it drives the rotating plate 24, which in turn drives the fifth rotating shaft 23 to rotate. As the fifth rotating shaft 23 rotates, it pulls one end of the linkage rod 22, causing the linkage rod 22 to rotate. The other end pulls the fourth rotating shaft 21, which in turn drives the moving block 20, causing the moving block 20 to move the clamping block 19 towards the steel pipe body 8, thereby clamping and fixing both ends of the steel pipe body 8. Finally, the first motor 16 and the second motor 17 are started. The output end of the second motor 17 drives the saw blade 5 to rotate through the first rotating shaft 6, and the output end of the first motor 16 drives the screw 15 to rotate. As the screw 15 rotates, it drives the lifting block 3, causing the lifting block 3 to move vertically inside the fixed frame 2. As the device moves downwards, the lifting block 3 lowers, simultaneously driving the fixed cover 4. The fixed cover 4, via the first rotating shaft 6, drives the saw blade 5 and the protective cover 7. As the protective cover 7 moves downwards, the connecting rod 12, through the cooperation of the third rotating shaft 13 and the fixed block 14, pulls the second rotating shaft 11. The second rotating shaft 11 pulls the protective cover 7, causing it to slowly open around the first rotating shaft 6, thus allowing the bottom of the saw blade 5 to cut the steel pipe body 8. When the fixed cover 4 rises, the protective cover 7 closes, thus blocking the saw blade 5 and effectively preventing personnel from touching it. This not only blocks and protects the cutting blade, preventing personnel from contacting it, but also automatically controls the opening of the protective cover 7 during cutting, achieving the cutting purpose and improving the safety performance of the device. This solves the problem that while existing automated cutting devices can achieve automated cutting, they lack a protective structure at the cutting blade, leading to accidental cuts and significant safety hazards during operation.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
