Detailed implementation manners

[0027] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a laser cutting device for the production of a turbine vacuum machine, including a horn 1. A plurality of annularly arranged moving grooves 32 are provided on the inner surface of the annular horn 1. A moving block 20 is slidably connected in the moving groove 32. On the side of the moving block 20 facing outside the chute, a contact plate 22 is installed. On the side of the contact plate 22 facing the opening of the horn 1, a pressing block 21 is installed. The side of the pressing block 21 away from the contact plate 22 is connected to the connecting cylinder 15. On the side of the pressing block 21 facing the opening of the horn 1, a connecting cylinder 15 is installed. A connecting rod 16 is inserted into the connecting cylinder 15. On the side of the connecting rod 16 away from the pressing member, a laser cutting gun 13 is installed.

[0028] A plurality of pressing structures composed of a moving block 20, a contact plate 22 and a pressing block 21 are slid in the moving groove 32. When the pipe contacts the contact plate 22, it will push the contact plate 22 to move towards the end of the horn 1. Then, the moving block 20 installed on the contact plate 22 gradually approaches the pipe. When the pressing block 21 contacts the plate material, it presses the pipe. At this time, the pipe can no longer move, and the position of the pipe is limited. At the same time, the laser cutting gun 13 is connected to the pressing block 21 by the connecting rod 16 and the connecting cylinder 15. When the pressing block 21 contacts the pipe, the laser cutting gun 13 and the pipe are at a suitable cutting distance, and it is adapted to pipes of different sizes, as well as the pressing of pipes of different sizes by the pressing block 21.

[0029] A first measuring rod 5 is inserted into the horn 1. At one end of the first measuring rod 5 in the horn 1, an abutting plate 33 is installed. The abutting plate 33 contacts the contact plate 22. When the pipe pushes the contact plate 22 to move towards the end of the horn 1, the contact plate 22 pushes the abutting plate 33 and the first measuring rod 5 to move towards the end of the horn 1. The moving length of the first measuring rod 5 is the length of the pipe entering the horn 1.

[0030] On the side of the contact plate 22 away from the moving block 20, a vertical groove is provided. An H-shaped block 26 is slidably connected in the vertical groove. On one side of the H-shaped block 26 in the vertical groove, an elastic member is installed. The elastic member is a spring. The elastic member is in a normal state. The end of the elastic member away from the H-shaped block 26 is installed in the vertical groove. On the same side of the H-shaped block 26 and the pressing block 21, a triangular block 27 is installed. The end of the triangular block 27 away from the H-shaped block 26 is in contact with the pressing block 21.

[0031] Before the pipe contacts the contact plate 22, it contacts the triangular block 27. After the pipe contacts the pressing block 21, the pressing block 21 restricts the pipe, causing the pipe to squeeze the triangular block 27 and continue to approach the contact plate 22, making the elastic member in a squeezed state, and enabling the triangular block 27 to assist in clamping the inside of the pipe.

[0032] On one side of the end of the horn barrel 1, two vertical plates 6 are provided. Between the two vertical plates 6, a first conical wheel 8 and a second conical wheel 4 are provided. At both ends of the first conical wheel 8 and the second conical wheel 4, support rods 9 are installed. The support rods 9 are rotatably connected to the vertical plates 6. The first conical wheel 8 and the second conical wheel 4 are connected by a transmission belt 7. On the side of the vertical plate 6 away from the horn barrel 1, a servo motor 28 is provided. The output end of the servo motor 28 is connected to the support rod 9 of the first conical wheel 8. A toothed ring 3 is installed at the end of the horn barrel 1. The circumferential surface of the toothed ring 3 is engaged with a gear 2. The gear 2 is connected to the support rod 9 of the second conical wheel 4.

[0033] On the side of the H-shaped block 26 away from the elastic member, an extrusion cylinder 24 is installed. An extrusion rod 23 is inserted into the extrusion cylinder 24. The end of the extrusion rod 23 away from the extrusion cylinder 24 is installed in the vertical groove. A connecting pipe 25 is installed on the circumferential surface of the extrusion cylinder 24. A sealing cylinder 19 is installed on the vertical plate 6. The end of the connecting pipe 25 away from the extrusion cylinder 24 is connected to the sealing cylinder 19. A moving rod 18 is inserted into the end of the sealing cylinder 19 away from the connecting pipe 25. A limiting ring 17 is installed at the end of the moving rod 18 away from the sealing cylinder 19. The limiting ring 17 is sleeved on the circumferential surface of the transmission belt 7.

[0034] Utilize the adjustment structure to rotate and link with the speed change structure composed of the first conical wheel 8, the second conical wheel 4, and the transmission belt 7, thereby changing the rotation speed of the horn barrel 1, so that the thicker the pipe is inserted into the horn barrel 1, the slower the rotation speed of the horn barrel 1 is, avoiding adhesion after the laser cutting gun 13 cuts the pipe.

[0035] The annular surface of the horn 1 is provided with an annular ring 10. The annular surface of the annular ring 10 is provided with a chute. A plurality of sliders 11 are slidably connected in the chute. The sliders 11 are connected to the horn 1. The horn 1 is connected to the annular ring 10 by the sliders 11, so that the horn 1 can rotate within the annular ring 10. A support ring 12 is provided on the opening side of the horn 1. A plurality of round holes are provided on the side surface of the support ring 12. A plurality of second measuring rods 14 are installed on the side of the annular ring 10 facing the support ring 12. The second measuring rods 14 are inserted into the round holes. A clamping block 29 is installed on the annular surface of the second measuring rods 14.

[0036] When the pipe further presses the horn 1, the horn 1 will move to the side away from the support ring 12. The horn 1 drives the position of the second measuring rod 14 in the round hole to change, thereby measuring the moving distance of the pipe. The cutting length of the pipe is finally obtained by the measurement of the first measuring rod 5 and the second measuring rod 14.

[0037] An annular groove 31 is provided on the annular inner surface of the support ring 12. A limiting block 30 is slidably connected in the annular groove 31. A slot is provided on the side of the limiting block 30 facing outside the chute. The laser cutting gun 13 is inserted into the slot. The position of the laser cutting gun 13 is limited by the limiting block 30 to prevent the position deviation of the laser cutting gun 13 when it rotates.

[0038] In summary, for this laser cutting device for the production of a turbine vacuum machine, during use, first insert the pipe from the limiting ring 17 and contact the multiple triangular plates inside the horn 1, and push the contact plate 22 to move into the horn 1. As the contact plate 22 moves, the pressing block 21 gradually contacts the pipe and presses the pipe. At the same time, the laser cutting gun 13 also moves to the appropriate cutting distance for cutting the pipe and limits the position of the contact plate 22 inside the horn 1. Subsequently, when the pipe continues to enter the horn 1, it will press the triangular block 27, causing the triangular block 27 to move to the side away from the pressing block 21 until the pipe contacts the contact plate 22, reaching the maximum distance into the horn 1. The first measuring rod 5 also moves outside the horn 1 under the push of the contact plate 22 and measures the length of the pipe entering the horn 1.

[0039] Subsequently, continue to move the pipe into the horn 1. At this time, the whole horn 1 moves to the side away from the support ring 12. During the movement, the second measuring rod 14 moves to the side away from the support ring 12 together with the horn 1 until the clamping block 29 contacts the support ring 12. At this time, the pipe reaches the required length for use.

[0040] After the pipe stops moving, start the servo motor 28 and the laser cutting gun 13. Start the servo to drive the first conical wheel 8 to rotate. The first conical wheel 8 drives the second conical wheel 4 to rotate through the transmission belt 7. The rotation of the second conical wheel 4 drives the gear 2 to rotate. The rotation of the gear 2 further drives the horn 1 and multiple parts installed on the horn 1 to rotate together, and the laser cutting gun 13 also rotates together under the drive of the pressing block 21 to cut the pipe.

[0041] Before the pipe contacts the contact plate 22, it is necessary to squeeze the triangular block 27 so that the triangular block 27 contacts the inner annular surface of the pipe. Therefore, the direct distance between the triangular block 27 and the pressing block 21 is the thickness of the pipe. When the pipe is thicker, the distance between the triangular block 27 and the pressing block 21 is larger, and the extrusion rod 23 will also extend more outside the extrusion cylinder 24. A negative pressure is generated inside the extrusion cylinder 24, and then the moving rod 18 moves into the sealing cylinder 19. At this time, the limiting ring 17 pulls the transmission belt 7 towards the horn 1 under the pull of the moving rod 18. At this time, the transmission ratio between the first conical wheel 8 and the second conical wheel 4 changes, causing the rotational speed of the second conical wheel 4 to decrease. After the rotational speed of the second conical wheel 4 decreases, the horn 1 will also reduce its rotational speed under the cooperation of the gear ring 3 and the gear 2, so that the cutting speed of the laser cutting gun 13 for the pipe decreases, avoiding adhesion after the laser cutting gun 13 cuts the pipe. On the contrary, the thinner the pipe, the faster the rotational speed of the laser cutting gun 13, increasing the pipe cutting efficiency.

Many modifications and variations are obvious to those of ordinary skill in the art.
