[0004] In the aforementioned application document, a steel pipe positioning and conveying mechanism is used to move the steel pipe to a designated position, and then a laser cutting actuator is used to perform the corresponding cutting operation on the steel pipe. When the laser cutter moves quickly to perform a rapid cutting operation on the steel pipe, the fixed steel pipe may shake due to the rapid movement of the laser cutter, thereby affecting the cutting effect of the device.

[0014] Preferably, the second bevel gear is located on the side of the first bevel gear and is in contact with the first bevel gear.

[0015] This invention provides a laser cutting device for steel pipes. It has the following beneficial effects: (1) When the steel pipe laser cutting equipment needs to perform a rapid cutting operation, the lead screw driven by the servo motor rotates rapidly, which drives the moving table and the laser cutter to move rapidly.

[0017] (3) When the lead screw is in the rotating state, the steel pipe laser cutting equipment can drive the first bevel gear to rotate, which in turn drives the second bevel gear to rotate. The second bevel gear drives the rotating rod to rotate, which in turn drives the second elastic cam to rotate.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1, please refer to Figures 1-5 A laser cutting device for steel pipes, comprising: The cutting table 100 has a pipe positioning block 200 installed inside it, and a lead screw 300 driven by a servo motor is rotatably connected inside the cutting table 100. A movable stage 400 passes through the cutting stage 100 and is slidably connected to it. A laser cutter 500 driven by an electric telescopic rod is mounted on the bottom of the movable stage 400. The steel pipe to be cut is placed on the pipe positioning block 200, and the laser cutter 500 driven by the electric telescopic rod is activated to perform the corresponding cutting operation on the steel pipe. When a rapid cutting operation is required on the steel pipe, the lead screw 300 driven by the servo motor rotates rapidly, thereby driving the movable stage 400 and the laser cutter 500 mounted on the movable stage 400 to move rapidly. A hydraulic chamber 601 is mounted on the outer side of the lead screw 300. A pressure plate 609 is slidably connected inside the pipe positioning block 200. A force-bearing plate 611 is connected to the side of the pressure plate 609 via a spring 610. A transmission component for transmission is mounted between the hydraulic chamber 601 and the force-bearing plate 611. The transmission component includes a sliding block 603 slidably connected to the hydraulic chamber 601 via a piston. A spring 602 is mounted on the side of the sliding block 603. When the lead screw 300 rotates rapidly, it drives the hydraulic chamber 601 mounted on its outer side to rotate rapidly. This causes the sliding block 603 inside the hydraulic chamber 601 to stretch the spring 602 under the action of centrifugal force, sliding along the inner wall of the hydraulic chamber 601 and squeezing the oil originally stored in the hydraulic chamber 601.

[0022] A transmission plate 604 is slidably connected to the side of hydraulic chamber 601 via a piston. A second hydraulic chamber 605 is mounted on the side of the cutting table 100. A force-bearing rod 606 is slidably connected to one end of hydraulic chamber 605 via a piston. The force-bearing rod 606 is located at the bottom of transmission plate 604 and is in contact with it. When the oil in hydraulic chamber 601 is compressed, it flows towards the end near transmission plate 604, causing transmission plate 604, which is slidably connected to hydraulic chamber 601 via a piston, to extend out of hydraulic chamber 601. At this time, transmission plate 604 extends synchronously as it rotates, thus compressing the force-bearing rod 606 and causing it to move to the bottom. This, combined with the movement of hydraulic chamber 605, allows the force-bearing rod 606 to compress the oil within hydraulic chamber 605 during its movement.

[0023] The other end of the hydraulic chamber 2 605 is slidably connected to a transmission rod 1 607 via a piston. A force-bearing plate 1 611 is located on the side of the transmission rod 1 607 and is in contact with it. A spring 2 608 is mounted on the side of the force-bearing rod 1 606. When the oil in the hydraulic chamber 2 605 is compressed, it flows towards the transmission rod 1 607, causing the transmission rod 1 607, which is slidably connected between the hydraulic chambers 2 605 via a piston, to move. This compresses the force-bearing plate 1 611 and applies an additional force to the inner wall of the steel pipe fitted outside the pipe positioning block 200 via the spring 3 610 and the pressure plate 609. In this way, the device's support effect on the inner wall of the steel pipe is improved, the possibility of the steel pipe swaying is reduced, and the cutting effect of the device is improved.

[0024] When the cutting operation is completed or when rapid cutting is not required, the lead screw 300 stops rotating or is in a slow rotation state. The sliding block 603 then loses the centrifugal force and resets under the action of spring 602. Similarly, the transmission plate 604 resets, and the force rod 606 loses the action of the transmission plate 604 and resets under the action of spring 608. Similarly, the transmission rod 607 resets.

[0025] In use, the steel pipe to be cut is placed on the pipe positioning block 200, and the laser cutter 500 driven by the electric telescopic rod is activated to perform the corresponding cutting operation on the steel pipe. When a rapid cutting operation is required, the lead screw 300 driven by the servo motor rotates rapidly, thereby driving the moving table 400 and the laser cutter 500 mounted on the moving table 400 to move rapidly. At this time, the lead screw 300 simultaneously drives the hydraulic chamber 601 mounted on its outer side to rotate rapidly, causing the sliding block 603 located in the hydraulic chamber 601 to stretch the spring 602 under the action of centrifugal force and slide along the inner wall of the hydraulic chamber 601, squeezing the oil originally stored in the hydraulic chamber 601. This causes the oil to flow towards the end near the transmission plate 604, driving the transmission plate 604, which is slidably connected to the hydraulic chamber 601 by a piston, to extend out of the hydraulic chamber 601. At this time, the transmission plate 604 extends synchronously when rotating, thus squeezing the force rod. The first rod 606 moves downwards, and the second hydraulic chamber 605, which is connected to the first rod 606 by a piston, compresses the oil in the second hydraulic chamber 605 during its movement. The oil then flows towards the side closer to the first transmission rod 607, causing the transmission rod 607, which is connected to the second hydraulic chamber 605 by a piston, to move. This compresses the first force plate 611 and applies an additional force to the inner wall of the steel pipe fitted outside the pipe positioning block 200 through the third spring 610 and the pressure plate 609. When the cutting operation is completed or when rapid cutting is not required, the lead screw 300 stops rotating or rotates slowly. The sliding block 603 then loses its centrifugal force and resets under the action of the first spring 602. Similarly, the transmission plate 604 resets, and the first rod 606, losing the action of the transmission plate 604, resets under the action of the second spring 608. Similarly, the transmission rod 607 resets.

[0026] Example 2, please refer to Figures 1-7Based on Embodiment 1, the cutting table 100 is internally equipped with a cleaning assembly 700 for cleaning debris. The cleaning assembly 700 includes a hydraulic chamber 3 701 mounted on the side of the cutting table 100, a cam 1 702 mounted on the outer side of the lead screw 300, and a force-bearing rod 2 703 slidably connected to one end of the hydraulic chamber 3 701 via a piston. The force-bearing rod 2 703 is located at the bottom of the cam 1 702 and is in contact with it. When the lead screw 300 is rotating, it drives the cam 1 702 mounted on its outer side to rotate. When the protruding part of the cam 1 702 rotates to the force-bearing rod 2 703, it can squeeze the force-bearing rod 2 703 and drive it to move downward. In conjunction with the hydraulic chamber 3 701 slidably connected to the force-bearing rod 2 703 via a piston, the force-bearing rod 2 703 can squeeze the oil in the hydraulic chamber 3 701 during its downward movement.

[0027] The other end of the hydraulic chamber 3 701 is connected to the transmission rod 2 704 via a piston. The inside of the cutting table 100 is rotatably connected to the torsion spring block 705. The outside of the torsion spring block 705 is fixedly connected to the cleaning plate 706. The cleaning plate 706 is located on the side of the transmission rod 2 704 and is in contact with the transmission rod 2 704. The side of the cutting table 100 is equipped with a collection chamber 707. When the oil in the hydraulic chamber 3 701 is squeezed, it flows towards the end near the transmission rod 2 704, causing the transmission rod 2 704, which is slidably connected to the hydraulic chamber 3 701 via a piston, to extend out of the hydraulic chamber 3 701. During the extension process, the transmission rod 2 704 can squeeze the cleaning plate 706 and drive the cleaning plate 706 to rotate. When the protruding part of the cam 1 702 continues to rotate and moves away from the force rod 2 703, the force rod 2 703 loses its restraint. Similarly, the cleaning plate 706 and the transmission rod 2 704 lose their restraint and are reset under the action of the torsion spring block 705. In this way, the cleaning plate 706 can reciprocate inside the cutting table 100, cleaning the debris on the bottom side of the inner wall of the cutting table 100 into the collection chamber 707, reducing the possibility that the device will be affected by the accumulation of debris.

[0028] In use, based on Embodiment 1, when the lead screw 300 is rotating, it can drive the cam 702 mounted on its outer side to rotate. When the protruding part of the cam 702 rotates to the force rod 703, it can squeeze the force rod 703 and drive it to move downward. This, combined with the hydraulic chamber 701 which is slidably connected to the force rod 703 via a piston, allows the force rod 703 to squeeze the oil in the hydraulic chamber 701 during its downward movement. This causes the oil to flow towards the end closer to the transmission rod 704, driving the force rod 703 to move downward. The transmission rod 704, which is connected to the piston, extends from the hydraulic chamber 701. During its extension, the transmission rod 704 can squeeze the cleaning plate 706 and drive it to rotate. When the protruding part of the cam 702 continues to rotate and moves away from the force rod 703, the force rod 703 loses its restraint. Similarly, the cleaning plate 706 and the transmission rod 704 lose their restraint and are reset under the action of the torsion spring block 705. In this way, the cleaning plate 706 can reciprocate inside the cutting table 100, cleaning the debris on the bottom side of the inner wall of the cutting table 100 into the collection chamber 707.

[0029] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, an auxiliary collection assembly 800 for collecting debris is mounted on the side of the cutting table 100. The auxiliary collection assembly 800 includes a rotating rod 801 located on the side of the cutting table 100. Since the cutting tables 100 are rotatably connected, a bevel gear 802 is fixedly connected to the outer side of the lead screw 300. When the lead screw 300 is rotating, it can drive the bevel gear 802 fixedly connected to it to rotate.

[0030] A second bevel gear 803 is fixedly connected to the top of the rotating rod 801. The second bevel gear 803 is located on the side of the first bevel gear 802 and is in contact with it. A second elastic cam 804 is fixedly connected to the outer side of the rotating rod 801. When the first bevel gear 802 rotates, it drives the second bevel gear 803, which meshes with it, to rotate. The second bevel gear 803 then drives the rotating rod 801, which is fixedly connected to it, to rotate. This causes the rotating rod 801 to drive the second elastic cam 804, which is fixedly connected to it, to rotate. During rotation, the second elastic cam 804 strikes the outer wall of the collection chamber 707, causing the collection chamber 707 and the debris inside to vibrate. This helps to organize the debris inside the collection chamber 707, making the device easier to use.

[0031] In use, based on Embodiment 1 and Embodiment 2, when the lead screw 300 is in a rotating state, the lead screw 300 can drive the bevel gear 802 fixedly connected to it to rotate, so that the bevel gear 802 drives the bevel gear 803 meshing with it to rotate, and the bevel gear 803 drives the rotating rod 801 fixedly connected to it to rotate, so that the rotating rod 801 drives the elastic cam 804 fixedly connected to it to rotate. During the rotation, the elastic cam 804 strikes the outer wall of the collection chamber 707 and causes the collection chamber 707 and the debris inside it to vibrate, thus sorting the debris in the collection chamber 707 to a certain extent.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
