[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0023] Reference Figure 1-4A steel structure automatic positioning and cutting device comprises a frame 1, a movable frame 2 is arranged inside the frame 1, a driving mechanism for driving the movable frame 2 to move is installed inside the frame 1, a hydraulic cylinder 3 is fixedly installed on the end surface of the movable frame 2, and a lifting frame 4 is fixedly installed on the output end of the hydraulic cylinder 3, a cutting mechanism 5 is installed on the side wall of the lifting frame 4, a protrusion 6 is fixedly installed on the top of the movable frame 2, a mounting rod 7 is arranged on the upper side of the inner part of the frame 1, a plurality of movable blocks 8 are slidably connected to the rod wall of the mounting rod 7, a pressure switch 9 is installed at the lower end of each movable block 8, and a contact pressure hemisphere 10 is fixedly installed at the lower end of the moving contact of each pressure switch 9.

[0024] A connecting block 11 is fixedly installed on the side wall of each movable block 8, and a plurality of spray pipes 12 are fixedly plugged into the end face of each connecting block 11. A solenoid valve 13 electrically connected to the pressure switch 9 is provided on the inner upper side of each spray pipe 12. Through this arrangement, when the pressure switch 9 is pressed, the corresponding solenoid valve 13 is energized and opened, and at this time, the coolant flows out through the spray pipe 12.

[0025] The driving mechanism includes a driving screw 14 rotatably arranged inside the frame 1, the rod wall of the driving screw 14 is transmission-connected with a screw nut, the movable frame 2 is located on the outside of the screw nut and is fixedly sleeved, a servo motor 15 is fixedly installed on the side wall of the frame 1, and the output end of the servo motor 15 is transmission-connected with the driving screw 14, wherein a limit rod (not shown in the figure) is installed inside the frame 1, and the limit rod is slidably connected with the movable frame 2 to ensure the horizontal and stable movement of the movable frame 2.

[0026] A U-shaped plate 16 is fixedly installed on the top of the frame 1, and a coolant inlet pipe 17 is fixedly inserted into the side wall of the U-shaped plate 16. One end of the coolant inlet pipe 17 is sealed, and a plurality of shunt pipes 18 are fixedly inserted into the pipe wall of the coolant inlet pipe 17. A manual valve 19 is installed inside each shunt pipe 18. The liquid inlet end of each spray pipe 12 is connected to the corresponding shunt pipe 18 through a connecting hose 20. Through this arrangement, it is convenient to add liquid to each spray pipe 12.

[0027] A limiting nut 21 is provided on both sides of each movable block 8, and each limiting nut 21 is threadedly connected to the rod wall of the mounting rod 7. Both ends of the mounting rod 7 are threadedly connected to the mounting disk 22. The two side walls of the frame 1 are threadedly connected to the limiting bolts 23.

[0028] Each of the liquid spraying pipes 12 is in a curved shape, and each of the liquid spraying pipes 12 is staggered with the movable frame 2 and the cutting mechanism 5. This arrangement can prevent the liquid spraying pipes 12 from affecting the normal movement of the movable frame 2 and the cutting mechanism 5.

[0029] In the present application, when in use, the steel structure to be cut is fixed under the frame, and then the cutting work is started. The servo motor 15 will rotate the driving screw 14, and with the cooperation of the screw nut, the movable frame 2 can move horizontally, thereby driving the protrusion 6 to move synchronously. When the protrusion 6 moves to the position of the pressure switch 9, the protrusion 6 will squeeze the contact hemisphere 10, thereby making the moving contact of the pressure switch 9 in a closed state. At this time, the servo motor 15 stops working immediately and starts the hydraulic cylinder 3 and the cutting mechanism 5 to work. After the cutting work at this position is completed, the hydraulic cylinder 3 drives the cutting mechanism 5 to move back and reset, and then the cutting mechanism 5 and the hydraulic cylinder 3 stop working, and the servo motor 15 continues to work, thereby driving the movable frame 2 to move to the position of the next pressure switch 9, and then continue the cutting work.

[0030] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
