In other embodiments of the present invention, a negative pressure adsorption mechanism may be used to move the tubing 200.
Further, as shown in fig. 7 to 9, the cutting device 40 includes a fixing frame 43, a supporting frame 44 is disposed on the fixing frame 43, and the clamping assembly 41 and the cutting assembly 42 are disposed on a surface of the supporting frame 44 at intervals; the clamping assembly 41 comprises a fixed seat 411 and a sucker 412 arranged on the fixed seat 411, the sucker 412 comprises at least two movable clamping jaws, the fixed seat 411 is arranged on the supporting frame 44, the fixed seat 411 is provided with a through hole for the pipe 200 to pass through, the movable clamping jaws are arranged in the through hole and are arranged along the circumferential interval of the through hole, each movable clamping jaw comprises a connecting end and an adsorption end, the connecting end is rotationally connected with the fixed seat 411, and the adsorption end is provided with a negative pressure adsorption hole for adsorbing and fixing the pipe 200.
The clamping assembly 41 on the cutting device 40 is used to machine the fixed pipe 200 as the pipe 200 is transported to the cutting station. The clamping assembly 41 in this embodiment includes a fixing seat 411 disposed on the supporting frame 44 and a suction cup 412 disposed on the fixing seat 411, where a through hole of the fixing seat 411 is disposed corresponding to the carrying track 32 of the feeding device 30. The pipe 200 is conveyed into the through hole of the fixing seat 411 by the feeding structure, and the sucker 412 arranged in the through hole of the fixing seat 411 is used for adsorbing and fixing the pipe 200, namely, a negative pressure adsorption hole arranged at the adsorption end of the sucker 412 adsorbs and fixes the pipe 200. Then, the cutting assembly 42 performs cutting operation, and when the pipe 200 is cut, the cutting assembly 42 may rotate around the pipe 200, or the fixing seat 411 may rotate to drive the pipe 200 to rotate, so as to accurately cut the pipe 200.
Further, as shown in fig. 8, the cutting device 40 further includes a negative pressure feeding mechanism 45, where the negative pressure feeding mechanism 45 is disposed on the fixing frame 43 or the supporting frame 44, and is located on a side of the supporting frame 44 away from the clamping assembly 41; the negative pressure feeding mechanism 45 comprises a first moving mechanism 451 arranged on the fixed frame 43, and the first moving mechanism 451 is connected with a negative pressure absorbing member; when the pipe 200 is transported, the negative pressure absorbing member absorbs the pipe 200, and the first moving mechanism 451 drives the pipe 200 to move toward the clamping assembly 41 through the negative pressure absorbing member.
Because the feeding mechanism 33 in this embodiment adopts a cylinder for feeding, the stroke of the cylinder is fixed, and the length of the cylinder is equal to the length of the piston, if the cylinder is adopted to realize the whole feeding of the pipe 200, the length of the cylinder is too long, the occupied space is too large, and the use is inconvenient. Accordingly, a negative pressure feeding mechanism 45 is provided on the cutting device 40 for assisting in the conveyance of the pipe 200. When the conveying stroke of the feeding mechanism 33 is reached, the negative pressure feeding mechanism 45 starts feeding work. When the negative pressure feeding mechanism 45 conveys the pipe 200, the negative pressure absorbing member absorbs and fixes the pipe 200, and the first moving mechanism 451 drives the pipe 200 to move towards the clamping assembly 41 through the negative pressure absorbing member.

Because negative pressure feeding mechanism 45 locates cutting device 40 and is located the one side that deviates from clamping assembly 41, when tubular product 200 cuts to remaining a little short distance, for example remaining length can only cut one section finished product, negative pressure feeding mechanism 45 can not transport tubular product 200 to cutting device 40 department completely, if do not cut tubular product 200, causes the waste of raw materials, therefore cutting device 40 still includes auxiliary feeding mechanism 46, auxiliary feeding mechanism 46 locates the one side that support frame 44 deviates from negative pressure feeding mechanism 45 to set up with clamping assembly 41 interval. When the remaining distance of the pipe 200 is short, the negative pressure clamping jaw 4611 of the auxiliary feeding mechanism 46 adsorbs and fixes the pipe 200, the second moving mechanism 461 drives the pipe 200 to move away from the clamping assembly 41 through the negative pressure clamping jaw 4611, and when the length of the pulled pipe 200 reaches the cutting requirement, the cutting assembly 42 cuts the pipe 200, so that the waste of raw materials is reduced.

Because the cutting of the thin-wall pipe 200 is realized in the embodiment, the blanking clamping jaw 52 is used for clamping the finished product of the pipe 200, or the pipe 200 can be clamped when the pipe 200 is cut, so that the auxiliary support of the pipe 200 is realized. During blanking, the blanking clamping jaw 52 clamps a finished product of the pipe 200 and conveys the finished product to the blanking support 51, so that the phenomenon of collision deformation when the pipe 200 directly falls to the blanking support 51 is avoided, and noise generated in the working process is reduced. The discharging bracket 51 is provided with a conveyor belt 511 for conveying the finished product of the pipe 200 to a finished product collecting place for collecting the finished product. Meanwhile, the supporting frame 44 or the fixing frame 43 is provided with a receiving hopper 53 for collecting waste materials generated in the process of cutting the pipe 200, the blanking bracket 51 is provided with a waste material conveying belt, and the waste material conveying belt is arranged below the receiving hopper 53 and is used for conveying the waste materials in the receiving hopper 53 so as to realize separate conveying of finished products and the waste materials.

The driving mechanism 47 drives the discharging gripper jaw 52 to rotate relative to the cutting device 40 so as to convey the gripped finished product of the pipe 200 to the driving belt of the discharging bracket 51. Since the auxiliary feeding mechanism 46 on the supporting frame 44 can move relative to the clamping device, the blanking clamping claw 52 can move relative to the cutting device 40 under the action of the driving mechanism 47 so as to clamp the finished product of the pipe 200.
Further, the automatic pipe cutting machine 100 further includes a dust suction device, which is disposed on the cutting device 40. The cutting assembly 42 may generate some metal dust during the process of cutting the pipe 200, and the metal dust may adhere to the surface of the pipe 200 to contaminate the pipe 200; the inside of cutting machine also can be entered into, and then influence the precision of cutting machine, and then influence the normal use of cutting machine, consequently, set up dust extraction for the metal dust that produces when absorbing tubular product 200 cutting. The dust collection device comprises a dust collection pipe and a dust collector connected with the dust collection pipe, when the dust collection device is used, the dust collection pipe is arranged in an inner hole of the pipe 200, and dust generated in the cutting process is timely pumped away and purified by the dust collection electrode through the dust collection pipe, so that the product quality and the working environment are improved. In this embodiment, the cutting bit 421 of the cutting assembly 42 is a laser cutting bit, and the dust suction pipe is disposed in the inner hole of the pipe 200, so that the laser cutting bit can be prevented from burning the inner wall of the pipe 200 when cutting the pipe 200.
