[0037] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] This embodiment provides a numerical control cutting device. Figure 1-Figure 3As shown, the CNC cutting device includes a crossbeam 1, a transmission assembly 3, a driving member 5, a position detection member 6 and a plurality of cutting assemblies 4. The crossbeam 1 has a first end 11 and a second end 12 along the length direction, and the second end 12 is provided with a stop member 2. The transmission assembly 3 includes a transmission belt 31 and two guide wheels 32, the two guide wheels 32 are rotatably arranged at the first end 11 and the second end 12, and the transmission belt 31 is sleeved on the two guide wheels 32. The cutting assembly 4 includes a moving body 41 and a cutting member 42 arranged on the moving body 41, and a plurality of moving bodies 41 are slidably arranged on the crossbeam 1, and the moving bodies 41 are all provided with a first locking member 43, and the first locking member 43 can selectively lock the corresponding moving body 41 with the transmission belt 31 so that the moving body 41 and the transmission belt 31 move synchronously. The driving member 5 can drive the moving body 41 closest to the first end 11 to slide along the crossbeam 1. The position detecting member 6 is disposed on the moving body 41 closest to the second end 12 . When the position detecting member 6 detects the stopping member 2 , the driving member 5 stops driving the moving body 41 closest to the first end 11 to move.

[0039] In the CNC cutting device, the operator drives the movable body 41 closest to the first end 11 toward the second end 12 through the driving member 5, and continues to push the other movable bodies 41 to move after encountering other movable bodies 41 on the way. When the position detection member 6 detects the stop member 2, the driving member 5 stops driving, causing all movable bodies 41 to stop moving.

[0040] At this time, all the moving bodies 41 are close to each other, which is the starting position. Then the operator controls the first locking member 43 of the moving body 41 closest to the first end 11 to lock the moving body 41 and the conveyor belt 31, and uses the driving member 5 to control the moving body 41 to move toward the first end 11, and the conveyor belt 31 starts to rotate under the drive of the moving body 41. When the distance between the cutting member 42 of the moving body 41 and the cutting member 42 of the second moving body 41 close to the first end 11 is the spacing required for cutting, the operator controls the first locking member 43 of the second moving body 41 close to the first end 11 to lock the conveyor belt 31, so that the second moving body 41 close to the first end 11 and the moving body 41 closest to the first end 11 move toward the first end 11 synchronously. When the distance between the second cutting member 42 close to the first end 11 and the third cutting member 42 close to the first end 11 is the spacing required for cutting, the operator controls the first locking member 43 of the third moving body 41 close to the first end 11 to lock the conveyor belt 31. The above operation is repeated until the spacing between all adjacent cutting pieces 42 is adjusted.

[0041] The numerical control cutting device can automatically adjust the spacing between the cutting members 42 according to the set size, and only uses one driving member 5 to provide power, so it has a simple structure and low cost.

[0042] It can be understood that when all the moving bodies 41 are close to each other, the distance between adjacent cutting members 42 is X1. If the actual required spacing is X2, the driving member 5 needs to drive the moving body 41 closest to the first end 11 to drive the conveyor belt 31 to move a distance X=X2-X1. In other words, each time the driving member 5 drives the moving body 41 closest to the first end 11 to move a distance X, the first locking member 43 of the cutting assembly 4 closest to the first end 11 that has not moved yet is controlled to lock the corresponding moving body 41 with the conveyor belt 31, and the setting is completed.

[0043] In actual use, the distance between adjacent cutting pieces 42 can also be adjusted according to the above method according to specific needs to complete cutting of different widths.

[0044] Among them, the first locking member 43 on the moving body 41 closest to the first end 11 can always lock the moving body 41 and the conveyor belt 31. At this time, it can be understood that the driving member 5 can also be set on the beam 1, and the driving member 5 is used to directly drive a guide wheel 32 to rotate, so that the conveyor belt 31 can drive the moving body 41 to move.

[0045] In order to reduce costs, the moving body 41 closest to the first end 11 can be fixedly connected to the conveyor belt 31 to reduce the use of a first locking member 43, and the connection method can be welding.

[0046] In order to prevent the deformation of the transmission belt 31 from affecting the adjustment accuracy, the transmission belt 31 is a steel belt.

[0047] The cutting member 42 is a straight cutting torch.

[0048] When the moving body 41 closest to the first end 11 moves toward the first end 11, the other moving bodies 41 are in an uncontrolled state and are prone to displacement. In order to improve the stability of the moving body 41 relative to the beam 1, the moving body 41 is also provided with a second locking member 44, which can lock the relative position between the moving body 41 and the beam 1.

[0049] Preferably, if Figure 2 As shown, the first locking member 43 is a cylinder, the moving body 41 is provided with a locking portion 411, the conveyor belt 31 passes between the output end of the cylinder and the locking portion 411, and the cylinder is configured to press the conveyor belt 31 toward the locking portion 411 so that the moving body 41 and the conveyor belt 31 move synchronously. The operator can press the conveyor belt 31 toward the locking portion 411 and continuously provide pressure by inflating the cylinder to drive the output end to extend, so as to lock the relative position of the moving body 41 and the conveyor belt 31.

[0050] The second locking member 44 is also a cylinder, and the output end of the cylinder presses against the crossbeam 1 to lock the position of the moving body 41 during the extension process.

[0051] In order to prevent the transmission belt 31 from sliding with the locking portion 411 or the output end of the cylinder, an elastic block 431 is provided at the output end of the cylinder. Figure 3 As shown. The elastic block 431 is deformed under the pressure of the cylinder, so that the friction coefficient between the elastic block 431 and the conveyor belt 31 increases, thereby improving the friction force. In order to further improve the friction coefficient, a plurality of protrusions are provided on the side of the elastic block 431 that contacts the conveyor belt 31.

[0052] Preferably, the CNC cutting device further comprises an elastic member 7, which is arranged at the second end 12, and the movable body 41 abuts against and compresses the elastic member 7 during the movement toward the second end 12. When the movable body 41 closest to the first end 11 pushes other movable bodies 41 to move toward the second end 12, the elastic member 7 can make the movable bodies 41 fit closely together, prevent gaps from being generated between adjacent movable bodies 41, and ensure that the spacing between each cutting member 42 is X1. Since the spacing adjustment between the final cutting members 42 of the CNC cutting device is related to the initial spacing between the cutting members 42, the elastic member 7 can improve the adjustment accuracy.

[0053] Preferably, the driving member 5 is a servo motor, which is disposed on the moving body 41 closest to the first end 11, and the rotating shaft of the servo motor is provided with a gear, and the crossbeam 1 is provided with a rack 13 meshing with the gear along the length direction. The servo motor has the advantage of high precision, and the operator can control the rotation of the servo motor, and the distance between the cutting members 42 can be accurately adjusted through the rotation speed of the servo motor and the pitch of the gear and the rack 13.

[0054] Preferably, the moving body 41 is provided with a lifting assembly 8 in the vertical direction, and the output end of the lifting assembly 8 is connected to the cutting member 42. The lifting assembly 8 can adjust the distance between the cutting member 42 and the workpiece to be cut, thereby adjusting according to the specific parameters of the workpiece to improve the cutting effect and quality.

[0055] Among them, the lifting assembly 8 includes a lifting member 81, a screw rod 82 and a guide column 83. The screw rod 82 is rotatably arranged on the moving body 41 along the vertical direction. The screw rod 82 passes through the lifting member 81 and is threadedly connected with the lifting member 81. The guide column 83 is arranged on the moving body 41 along the vertical direction. The lifting member 81 is provided with a guide hole. The guide column 83 passes through the guide hole. The cutting member 42 is fixedly connected to the lifting member 81.

[0056] It is understandable that, in order to prevent the cutting direction of the cutting assembly 4 from being offset, the beam 1 is provided with two slide rails 14 spaced apart in the vertical direction, and the moving body 41 is provided with two sliders 45 slidably connected to the two slide rails 14 .

[0057] Preferably, the CNC cutting device further comprises two guide rails, which are arranged in a direction perpendicular to the beam 1. Support legs 15 are arranged at both ends of the beam 1. Through slots are arranged at the bottom of the support legs 15. The support legs 15 are slidably arranged on the guide rails through the through slots. After the CNC cutting device adjusts the spacing between the cutting pieces 42, it moves along the direction perpendicular to the beam 1 through the guide rails to complete the cutting of the workpiece to be cut.

[0058] Preferably, the CNC cutting device further comprises a control component 9, which is electrically connected to the position detection component 6 and the driving component 5. When the position detection component 6 detects the stopping component 2, the control component 9 controls the driving component 5 to stop moving.

[0059] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
