[0026] See Figures 1-8 As shown, the technical solution adopted in this specific embodiment is as follows: it includes a shearing mechanism 1, a shearing cylinder 2, a robotic arm 3, a robotic arm cylinder 4, a base turntable 5, and a connecting flange 6. The shearing mechanism 1 is mechanically connected to the shearing cylinder 2, and the shearing mechanism 1 is connected to the upper part of the robotic arm cylinder 4 through the connecting flange 6. The lower end of the robotic arm cylinder 4 is installed on the base turntable 5, and the robotic arm cylinder 4 is provided on the base turntable 5. The robotic arm cylinder 4 is mechanically connected to the robotic arm 3.

[0027] The shearing mechanism 1 comprises a steel bar outlet clamping mechanism 11, a steel bar clamping jaw 12, a shearing jaw 13, a laser sensor 14, a steel bar inlet clamping mechanism 15, a protective shell 16, an inlet motor 17, and an outlet motor 18. The inlet motor 17 is installed above the protective shell 16 and mechanically connected to the steel bar outlet clamping mechanism 11. The outlet motor 18 is installed below the protective shell 16 and mechanically connected to the steel bar inlet clamping mechanism 15. The steel bar clamping jaw 12 is arranged at the lower end of the shearing jaw 13, which is mechanically connected to the shearing cylinder 2. The laser sensor 14 is arranged on the protective shell 16. During the shearing operation, the worker only needs to place the steel bar into the steel bar inlet clamping mechanism 15. Then the steel bar inlet clamping mechanism 15 will make the steel bar pass through the steel bar clamping jaw 12 and the shearing jaw 13 in turn and then enter the steel bar outlet clamping mechanism 11. After the steel bar enters, the laser sensor 14 will record the length of the steel bar and feed back to the control terminal. When the length reaches the set value, the shearing cylinder 2 will drive the shearing jaw 13 to shear the steel bar, and the steel bar clamping jaw 12 will clamp the steel bar to prevent it from loosening and falling off. The inlet motor 17 and the outlet motor 18 provide power for the steel bar inlet clamping mechanism 15 and the steel bar outlet clamping mechanism 11, respectively.

[0028] More specifically, the laser sensor 14 is provided with at least two and symmetrically distributed on the left and right sides of the inner wall of the protective shell 16. The laser sensor 14 can measure the length, but when the measured length of the steel bar reaches the set value, it will drive the shearing cylinder 2 to drive the shearing jaw 13 to shear the steel bar.

[0029] More specifically, the steel bar clamping jaw 12 comprises a clamping cylinder 12-1, a clamping head 12-2, and a clamping anti-slip plate 12-3. The clamping anti-slip plate 12-3 is bolted to the clamping head 12-2, and the clamping head 12-2 is mechanically connected to the clamping cylinder 12-1. When shearing the steel bar and clamping the steel bar is needed, the clamping cylinder 12-1 will drive the clamping head 12-2 to clamp the steel bar. The clamping anti-slip plate 12-3 can increase the clamping ability of the clamping head 12-2 to prevent the steel bar from loosening and falling off.

[0030] More specifically, the shearing jaw 13 comprises a linkage rod 13-1, a shearing head 13-2, and a mounting base 13-3. The shearing head 13-2 is mechanically connected to the shearing cylinder 2 through the linkage rod 13-1, and the shearing cylinder 2 and the clamping cylinder 12-1 are respectively installed at the upper and lower ends of the mounting base 13-3. During the shearing operation, the shearing cylinder 2 drives the shearing head 13-2 through the linkage rod 13-1 to shear the steel bar. The mounting base 13-3 can fix the steel bar clamping jaw 12 and the shearing cylinder 2 on the protective shell 16.

[0031] More specifically, the steel bar inlet clamping mechanism 15 includes a rear fixed sheet 15-1, a push connecting plate 15-2, a push cylinder 15-3, a clamping conveyor belt 15-4, and a front fixed sheet 15-5. The inlet motor 17 is in transmission connection with the clamping conveyor belt 15-4 through the rear fixed sheet 15-1, and the output end of the inlet motor 17 is movably connected to the front fixed sheet 15-5. The rear fixed sheet 15-1 and the front fixed sheet 15-5 are fixedly connected to the push connecting plate 15-2, and the push connecting plate 15-2 is connected to the push cylinder 15-3. When the steel bar is being cut or after the steel bar is cut, the push cylinder 15-3 will push the push connecting plate 15-2, and the clamping conveyor belt 15-4 will be driven by the rear fixed sheet 15-1 and the front fixed sheet 15-5 to move inward, so that the steel bar inlet clamping mechanism 15 and the steel bar outlet clamping mechanism 11 can clamp the steel bar.

[0032] More specifically, the structure of the steel bar outlet clamping mechanism 11 is the same as that of the steel bar inlet clamping mechanism 15. The same structure is adopted to manufacture the steel bar outlet clamping mechanism 11 and the steel bar inlet clamping mechanism 15, which is convenient for production, installation, adjustment, and subsequent maintenance and replacement.

[0033] More specifically, the mechanical arm 3 is provided with a plurality of hydraulic cylinders 301 for providing power to the mechanical arm 3.

[0034] The operation method of the steel bar fixed-length automatic cutting device and method is as follows:

[0035] 1) Adjust the working posture of the cutting mechanism 1 by the mechanical arm 3;

[0036] 2) Adjust and control the connecting flange plate 6 so that the cutting mechanism 1 is more suitable for the current work;

[0037] 3) Clamping the steel bar to be cut by the steel bar inlet clamping mechanism 15, and moving the steel bar forward to the steel bar outlet clamping mechanism 11 by the clamping conveyor belt 15-4;

[0038] 4) When the steel bar is driven by the clamping conveyor belt 15-4 to the laser sensor 14, the laser sensor 14 starts to measure the length;

[0039] 5) When the steel bar moves to the set length, the cutting cylinder 2 drives the cutting tongs 13 to cut the steel bar, and the steel bar clamping tongs 12 clamp the steel bar;

[0040] 6) Repeat the above steps until the end.

[0041] The working principle of the present application: the mechanical arm 3 solves the problem of not easy to send the reinforcement into the cutting opening. When it is needed to start cutting the reinforcement, the mechanical arm 3 moves to the specified position, so that the worker can better send the reinforcement into the empty opening of the clamping conveyor belt 15-4 of the reinforcement inlet clamping mechanism 15. After the reinforcement is sent, the device can start working, and the worker can also lift the height of the cutting mechanism 1 through the mechanical arm 3, so that the reinforcement falls to the ground after cutting, preventing the reinforcement from being accumulated at the reinforcement outlet clamping mechanism 11 after cutting, and increasing a plurality of laser sensors 14 at the cutting position of the cutting clamp 13, which measures the length of the reinforcement by using the laser sensor 14, greatly increasing the cutting speed of the cutting mechanism 1, being more accurate and efficient, greatly reducing the risk of worker operation, and the cutting mechanism 1 and the mechanical arm 3 are connected through the connecting flange plate 6, so that the cutting mechanism 1 is more flexible and variable. In the face of the problem of reinforcement blockage, the cutting mechanism 1 can be directly made vertical, then shaken to make the blocked part smooth, reduce the intervention of workers, prevent workers from being hurt by the rebounding reinforcement when dredging, greatly reduce the risk cost and safety problems of handling emergency events, and the base turntable 5 can drive the device to rotate.

[0042] The above is only used to illustrate the technical solutions of the present application, not to limit it. Other modifications or equivalent replacements of the technical solutions of the present application made by those skilled in the art should be covered in the scope of the claims of the present application, as long as they do not deviate from the spirit and scope of the present application.
