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.

[0027] See also Figures 1 to 7 The present invention describes the above technical solution in detail through the following embodiments:

[0028] The steel bar cutting machine based on construction construction includes: an operating table 1; a conveying box 2 is provided on the top of the operating table 1, a steel bar body 3 is provided inside the conveying box 2, a clamping box 4 is provided on the side of the operating table 1 away from the conveying box 2, and four clamping claws 5 are provided on the clamping box 4 near the steel bar body 3, a gantry 6 is provided between the conveying box 2 and the clamping box 4, and the gantry 6 is fixedly connected to the operating table 1; a power mechanism 7 for conveying the steel bar body 3 is provided inside the conveying box 2; a locking mechanism 8 for clamping and fixing the steel bar body 3 is provided inside the clamping box 4, the staff places the steel bar body 3 into the conveying box 2, and the power mechanism 7 inside the conveying box 2 accurately conveys the steel bar body 3, and then controls the clamping claws 5 to clamp and fix the steel bar body 3 through the locking mechanism 8 inside the clamping box 4, and finally cuts the steel bar body 3.

[0029] like Figure 4 As shown, the power mechanism 7 includes: the interior of the conveying box 2 is rotatably connected to two first rotating shafts 9, one end of the first rotating shaft 9 is rotatably connected to the conveying box 2, the other end of the first rotating shaft 9 passes through the conveying box 2 and extends to the synchronous wheel 10, the two synchronous wheels 10 are connected by a synchronous belt 11, the outer surface of the first rotating shaft 9 located inside the conveying box 2 is fixedly connected to the conveying roller 12, and the conveying roller 12 is adapted to the steel bar body 3; one end of the first rotating shaft 9 away from the synchronous wheel 10 passes through the conveying box 2 and extends to the motor 13, the motor 13 is fixedly connected to the conveying box 2, and the first rotating shaft 9 is fixedly connected to the output end of the motor 13; an elastic mechanism 14 that applies pressure to the steel bar body 3 is provided on the side of the steel bar body 3 away from the conveying roller 12, and the motor 13 is started. The output end of the motor 13 drives the first rotating shaft 9, and while rotating, it drives the two first rotating shafts 9 to rotate synchronously through the cooperation of the synchronous wheel 10 and the synchronous belt 11. When the two first rotating shafts 9 rotate, they drive the conveying roller 12, and the two conveying rollers 12 cooperate with the elastic mechanism 14 to accurately move and convey the steel bar body 3.

[0030] like Figure 3 As shown, the elastic mechanism 14 includes: a pressure frame 15 is provided on the side of the steel bar body 3 away from the conveying roller 12, and the inner sides of the pressure frame 15 are rotatably connected to the second rotating shaft 16, and the middle outer surface of the second rotating shaft 16 is fixedly connected to the pressure roller 17; the top two sides of the pressure frame 15 are fixedly connected to the sliding rod 18, and the top of the sliding rod 18 passes through the conveying box 2 and extends to the limit plate 19, and the limit plate 19 is fixedly connected to the sliding rod 18 respectively. Two springs 20 are provided between the pressure frame 15 and the conveying box 2, and the springs 20 are respectively sleeved on the outer surface of the sliding rod 18. The springs 20 squeeze the pressure frame 15 through the conveying box 2, and the pressure frame 15 passes through the second rotating shaft 16. The second rotating shaft 16 drives the pressure roller 16 to apply pressure to the steel bar body 3, thereby increasing the friction between the conveying roller 12 and the steel bar body 3.

[0031] like Figure 2 、 Figure 5 as well as Figure 6 As shown, the locking mechanism 8 includes: a flat screw disk 21 that is internally rotatably connected to the clamping box 4, and a moving block 22 is provided at the flat screw disk 21 near the clamping jaws 5.

The moving blocks 22 are respectively fixedly connected to the clamping jaws 5; a first bevel gear 23 is fixedly connected to the side of the flat screw disk 21 away from the clamping jaws 5, and the top of the first bevel gear 23 is meshed with a second bevel gear 24, and the center of the second bevel gear 24 is fixedly connected to a third rotating shaft 25, and the top of the third rotating shaft 25 passes through the clamping box 4 and extends to the turning handle 26, and the turning handle 26 is fixedly connected to the third rotating shaft 25. The staff rotates the turning handle 26, The turning handle 26 drives the third rotating shaft 25, the third rotating shaft 25 drives the second bevel gear 24, the second bevel gear 24 drives the first bevel gear 23, and the first bevel gear 23 drives the flat screw disk 21 to rotate. While the flat screw disk 21 rotates, the thread on its surface pushes the moving block to move in the direction of the steel bar body 3. While the moving block 22 moves, it drives the clamping jaws 5, so that the four clamping jaws 5 clamp and position the steel bar body 3 at the same time. The four clamping jaws 5 can be controlled to clamp and fix the steel bar body 3 at the same time, and the steel bar body 3 can also be centrally positioned, thereby avoiding shaking of the steel bar body 3 during cutting, resulting in poor cutting accuracy.

[0032] like Figure 3 As shown, there are sliding grooves 27 on both sides of the moving block 22, and the clamping box 4 is fixedly connected with a limiting slide 28 near the sliding groove 27. The moving block 22 is slidably connected to the limiting slide 28 through the sliding groove 27, which can limit the moving block 22 so that the moving block 22 can slide flexibly inside the clamping box 4.

[0033] like Figure 5 As shown, a damping pad 29 is provided on one side of the clamping jaw 5 close to the steel bar body 3. The damping pad 29 is fixedly connected to the clamping jaw 5, thereby increasing the friction force at the contact point between the clamping jaw 5 and the steel bar body 3, thereby improving the stability of clamping the steel bar body 3.

[0034] like Figure 7As shown, the top of the gantry 6 is fixedly connected to a hydraulic cylinder 30, the telescopic end of the hydraulic cylinder 30 passes through the gantry 6 and extends to the cutting knife 31, the cutting knife 31 is fixedly connected to the telescopic end of the hydraulic cylinder 30, and the operating table 1 is fixedly connected to a knife seat 32 near the cutting knife 31, the knife seat 32 is adapted to the cutting knife 31, and both sides of the cutting knife 31 are fixedly connected to the limiting blocks 33, the interior of the limiting blocks 33 are slidably connected to the limiting rod 34, and the two ends of the limiting rod 34 are respectively fixedly connected to the gantry 6 and the operating table 1, the telescopic end of the hydraulic cylinder 30 drives the cutting knife 31, and the cutting knife 31 drives the limiting block 33. The limiting block 33 slides downward through the cooperation of the limiting rod 34, thereby controlling the cutting knife 31 to descend horizontally, so that the cutting knife 31 cuts the steel bar body 3 through the cooperation of the knife seat 32.

[0035] Working principle: The staff places the steel bar body 3 inside the conveying box 2 and starts the motor 13. The output end of the motor 13 drives the first rotating shaft 9, and while rotating, it drives the two first rotating shafts 9 to rotate synchronously through the cooperation of the synchronous wheel 10 and the synchronous belt 11. The two first rotating shafts 9 drive the conveying roller 12 while rotating. At the same time, the spring 20 squeezes the pressure frame 15 through the conveying box 2, and the pressure frame 15 passes through the second rotating shaft 16. The second rotating shaft 16 drives the pressure roller 16 to apply pressure to the steel bar body 3, thereby increasing the friction between the conveying roller 12 and the steel bar body 3. The two conveying rollers 12 accurately move and convey the steel bar body 3 through the cooperation of the pressure roller 16. The steel bar body 3 can be accurately moved and conveyed, so that the device can accurately cut the steel bar body 3, which solves the problem that the existing steel bar cutting machine based on construction does not have the purpose of moving and conveying steel bars. Due to the large overall weight of the steel bars, it is inconvenient for the staff to move the steel bars, and the staff's movement accuracy of the steel bars is poor and the practicality is poor.

[0036] The staff rotates the handle 26, the handle 26 drives the third rotating shaft 25, the third rotating shaft 25 drives the second bevel gear 24, the second bevel gear 24 drives the first bevel gear 23, and the first bevel gear 23 drives the flat screw disk 21 to rotate. While the flat screw disk 21 rotates, the thread on its surface pushes the moving block to move in the direction of the steel bar body 3. While the moving block 22 moves, it drives the clamping jaws 5, so that the four clamping jaws 5 clamp and position the steel bar body 3 at the same time. The four clamping jaws 5 can be controlled to clamp and fix the steel bar body 3 at the same time, and the steel bar body 3 can also be centrally positioned, thereby avoiding shaking of the steel bar body 3 during cutting, resulting in poor cutting accuracy.
