[0002] The application of small-diameter steel pipes in the industrial field is increasing day by day, and a large number of steel pipes need to be cut at the ends or through holes. At present, the existing cutting equipment on the market requires manual operation for steel pipe cutting, including hoisting and loading, manually clamping with a chuck, operating the cutting, and hoisting and unloading. The operation steps are cumbersome, the automation degree of the equipment is low, and there are safety hazards to the operators. The batch cutting efficiency is even lower.

[0003] The currently disclosed patent: CN214443441U discloses a full-automatic small-diameter pipe cutting machine, which can achieve the purpose of automatically and quickly cutting small-diameter steel pipes by setting a guide rail, a transport bracket, and an induction head box when in use.

[0004] Based on the above search, the following problems exist when using the above patent: During the process of cutting a steel pipe, the small-diameter pipe cutting machine can achieve the purpose of automatically and quickly cutting small-diameter steel pipes by setting a guide rail, a transport bracket, and an induction head box. However, the small-diameter pipe cutting machine only clamps and fixes one end of the steel pipe to be cut. When the diameter size of the steel pipe is small, due to the overall light weight of the small-diameter steel pipe, during the process of cutting the steel pipe by the cutting machine, the cut-off end of the steel pipe is prone to shaking, which in turn affects the flatness of the steel pipe cutting surface and reduces the cutting quality of the steel pipe.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a full-automatic small-diameter cutting machine, including a cutting cabinet 1 and a steel pipe fixing device. A fixing frame 2 is fixedly connected to the top of the cutting cabinet 1. A three-jaw chuck 3 is rotatably installed inside the fixing frame 2. A steel pipe 4 is clamped and fixed inside the three-jaw chuck 3. An L-shaped bridge 5 is fixedly connected to the top of the cutting cabinet 1. A laser cutting head 6 is fixedly installed on the top of the L-shaped bridge 5. An electric telescopic rod 7 is fixedly installed on the right surface inside the cutting cabinet 1. The output end of the electric telescopic rod 7 is fixedly connected to a stop disk 8. The right end of the steel pipe 4 is in contact with the surface of the stop disk 8.

[0025] On the left side of the cutting cabinet 1, there is a steel pipe conveying mechanism. When this fully automatic small-diameter pipe cutting machine is in use, the staff can gradually convey the steel pipe 4 to the right through the conveying mechanism and clamp and fix the steel pipe 4 with the three-jaw chuck 3. At this time, the output shaft of the electric telescopic rod 7 drives the baffle 8 to move to the upper side. After the steel pipe 4 gradually slides to the right and contacts the baffle 8, the cutting length of the steel pipe 4 is positioned through the baffle 8. Inside the fixing frame 2, there is a chuck driving mechanism. The driving mechanism drives the three-jaw chuck 3 and the steel pipe 4 to rotate simultaneously, and then the surface of the steel pipe 4 can be cut in a circle by the laser cutting head 6. Moreover, the output end of the electric telescopic rod 7 can drive the baffle 8 to move downward and separate from the right end of the steel pipe 4, and the baffle 8 will not affect the rotation of the steel pipe 4.

[0026] The steel pipe fixing device includes a bridge 9, two sliders 11, a bidirectional threaded rod 12, a bidirectional motor 13, two arc-shaped clamping plates 14 and rolling balls 15. The bridge 9 is fixedly welded to the top of the cutting cabinet 1. A chute 10 is opened at the top of the bridge 9. Both sliders 11 are slidably connected inside the chute 10. The bidirectional threaded rod 12 is threadedly sleeved inside the two sliders 11. Opposite threads are provided at the front and rear ends of the bidirectional threaded rod 12. The rear end of the bidirectional threaded rod 12 is rotatably connected to the rear surface inside the chute 10. The bidirectional motor 13 is fixedly installed on the top of the bridge 9. The front end of the bidirectional threaded rod 12 is fixedly connected to the output end of the bidirectional motor 13. The two arc-shaped clamping plates 14 are respectively welded to the bottoms of the two sliders 11. The rolling balls 15 are evenly installed on the surfaces of the two arc-shaped clamping plates 14.

[0027] During the process of the laser cutting head 6 cutting the steel pipe 4, the bidirectional motor 13 starts and drives the bidirectional threaded rod 12 to rotate inside the two sliders 11. When the bidirectional threaded rod 12 rotates, it can drive the two sliders 11 to slide relatively. The two sliders 11 slide relatively and drive the two arc-shaped clamping plates 14 to slide relatively and clamp on the surface of the steel pipe 4 through the rolling balls 15. The steel pipe 4 is clamped and fixed by multiple rolling balls 15. When the steel pipe 4 rotates, it can drive the rolling balls 15 to roll. In this way, the stability of the steel pipe 4 during the cutting process is ensured, the steel pipe 4 is prevented from shaking during cutting, and then the flatness of the cutting surface of the steel pipe 4 is improved, and the cutting quality of the steel pipe 4 is enhanced.

[0028] After the steel pipe 4 is cut, the bidirectional motor 13 starts and drives the bidirectional threaded rod 12 to rotate reversely inside the two sliders 11, which can drive the two arc-shaped clamping plates 14 to slide away from each other and separate from the surface of the steel pipe 4. At this time, the steel pipe 4 can automatically fall to the inside of the cutting cabinet 1 under the action of its own gravity.

[0029] Working principle: For this fully automatic small-diameter pipe cutting machine, the steel pipe 4 is clamped and fixed by the three-jaw chuck 3. The output shaft of the electric telescopic rod 7 drives the stop disc 8 to move to the upper side. The steel pipe 4 gradually slides to the right and contacts the stop disc 8 for positioning. The driving mechanism drives the three-jaw chuck 3 and the steel pipe 4 to rotate simultaneously, and then the surface of the steel pipe 4 can be cut in a circle by the laser cutting head 6. During the cutting of the steel pipe 4 by the laser cutting head 6, the two-way motor 13 starts and drives the two-way threaded rod 12 to rotate inside the two sliders 11. When the two-way threaded rod 12 rotates, it drives the two sliders 11 to slide relatively. The two sliders 11 drive the two arc-shaped clamping plates 14 to slide relatively and clamp on the surface of the steel pipe 4 through the rolling balls 15, ensuring the stability of the steel pipe 4 during the cutting process, preventing the steel pipe 4 from shaking during cutting, thereby improving the flatness of the cutting surface of the steel pipe 4 and the cutting quality of the steel pipe 4.

[0030] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
