Description

Technical Field

[0001] The invention relates to the technical field of metal pipe processing, in particular to a metal pipe processing laser cutting machine. Background Art

[0002] Metal pipe fittings are a type of metal structure with a hollow cross-section and no seams around it. Due to their high strength, high rigidity, and light weight, they are widely used in nuclear power, aerospace, shipbuilding, vehicles, and other fields. For example, they are used in nuclear power reactor heat exchange systems, fuel transmission and environmental control systems in aircraft engines, hydraulic exhaust systems in aerospace vehicles, and various precision bent pipe fittings in automobiles. During the processing, their length needs to be controlled by cutting equipment.

[0003] For example, the patent application number disclosed on the China Patent Network is: 202322047361.9, and the patent name is: A laser cutting machine for processing metal pipe fittings, including a base; a feeding table connected to the base; a rotating device connected to the base and arranged at intervals with the feeding table; a clamping device installed on the rotating device; a mounting plate connected to one end of the base and provided with a first telescopic rod and a second telescopic rod; a laser cutting head installed on the first telescopic rod; a slag frame installed on the second telescopic rod; when working, first adjust the two telescopic rods to align the laser cutting head with the slag frame, the feeding table transports the metal pipe fittings to the specified position, the metal pipe fittings pass through the rotating device and are sleeved outside the slag frame, the clamping device clamps the metal pipe fittings, the rotating device drives it to rotate, the laser cutting head is started, and the slag frame is used to collect the cut slag until the cutting is completed, which can not only effectively cut the metal pipe fittings, but also collect the slag generated during the cutting process as much as possible.

[0004] However, the existing laser cutting machines have a relatively simple method of fixing pipes, which mainly relies on multiple telescopic rods for extrusion and fixation. The use of multiple telescopic rods for fixation requires manual adjustment of the position and strength of each telescopic rod, which increases the complexity and time cost of the operation. Since the multiple telescopic clamping parts move independently, the pipes will be offset due to extrusion errors after being extruded. This offset will affect the axis alignment effect and accuracy, and thus affect the cutting quality.

[0005] Secondly, after extrusion, the equipment needs to rotate and cut around the pipe. Independently operated equipment requires a lot of space, which limits the application of laser cutting machines in small spaces. The equipment's rotation and cutting requires a certain amount of time and steps, which will affect the installation efficiency of the pipe. Especially when a large number of pipes need to be processed quickly, the efficiency bottleneck of this method will be more obvious.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figures 1 to 8 As shown, a metal pipe processing laser cutting machine provided by the present invention comprises a machine base 1;

[0042] A bracket 2 fixedly connected to the top of the base 1;

[0043] A connecting structure 4 is installed on the left side of the bracket 2 through a rotating structure 3, and a cutting pipe 5 is connected to the surface of the connecting structure 4. The rotating structure 3 can drive the connecting structure 4 to rotate the cutting pipe 5. A laser emitting end 7 is installed on the top of the bracket 2 through an adjusting structure 6. The adjusting structure 6 can change the position of the laser emitting end 7 to avoid the laser emitting end 7 affecting the installation of the cutting pipe 5. The laser emitting end 7 is located at the top of the cutting pipe 5 and can cut the cutting pipe 5.

[0044] refer to Figure 3The connecting structure 4 is a component in the metal pipe processing laser cutting machine, which is responsible for fixing and rotating the cutting pipe 5. The structure mainly includes a connecting block 8 installed on the left side of the bracket 2 through the rotating structure 3. The number of connecting blocks 8 is several, and they are evenly arranged around the rotating structure 3. This design ensures that the cutting pipe 5 can maintain balance during the rotation process and avoids vibration or deviation caused by unstable center of gravity. Each connecting block 8 is connected to the rotating structure 3 through a solid structure to ensure its stability during high-speed rotation. The surface of each connecting block 8 is movably connected with a clamping plate 9 through a pin shaft. The design of the clamping plate 9 is flexible and can It can adapt to cutting pipe fittings 5 ​​of different diameters. The side of the splint 9 away from the connecting block 8 extends to the inside of the cutting pipe fitting 5 and is in close contact with the inner surface of the cutting pipe fitting 5. This contact method ensures that the cutting pipe fitting 5 will not loosen or fall off due to centrifugal force during rotation. In order to further enhance the stability of the cutting pipe fitting 5, a positioning structure 10 is arranged inside the bracket 2. The main function of the positioning structure 10 is to drive multiple splints 9 to swing at the same time, thereby squeezing and fixing the cutting pipe fitting 5. This fixing method not only ensures the stability of the cutting pipe fitting 5 during rotation, but also avoids cutting errors caused by vibrations generated during the cutting process.

[0045] As a technical optimization solution of the present invention, metal pipes of different diameters can be firmly clamped by evenly circumferentially arranged connecting blocks 8 and pin-movably connected clamps 9. This design enhances the versatility of the equipment, allowing the same equipment to process pipes of various specifications.

[0046] refer to Figure 5 The positioning structure 10 ensures the stability and accuracy of the cutting pipe 5 during the rotation and cutting process, and includes a transmission rod 11. The transmission rod 11 is arranged on the right side of the bracket 2, and its left end passes through the bracket 2 and extends to the left side of the bracket 2. The transmission rod 11, as the core component of the positioning structure 10, is responsible for transmitting power and driving the conical block 13 to move. The left end of the transmission rod 11 is fixedly connected with the conical block 13, and the outer surface of the conical block 13 is arranged to be inclined. This design enables the conical block 13 to produce an effective extrusion effect with the force plate 12 during the movement. When the transmission rod 11 moves horizontally under the drive of the transmission structure 14, the conical block 13 will also move accordingly. When the conical block 13 passes through the inclined part of the force plate 12, due to the inclined design of its outer surface, the conical block 13 will produce an outward extrusion force on the force plate 12. This extrusion force is transmitted to the clamping plate 9 through the force plate 12, thereby realizing the extrusion and fixation of the cutting pipe 5. The transmission structure 14 is arranged on the right side of the bracket 2, and is used to drive the transmission rod 11 to move horizontally.

[0047] As a technical optimization solution of the present invention, by utilizing the inclined design of the conical block 13 and the force-bearing plate 12, the horizontal movement of the transmission rod 11 can drive multiple clamps 9 to swing simultaneously, thereby evenly and firmly squeezing and fixing the pipe fittings. This positioning method not only improves the stability of the fixation, but also effectively avoids the shaking of the pipe fittings during the cutting process.

[0048] refer to Figure 5 The transmission structure 14 is an important part of the positioning structure 10 in the metal pipe processing laser cutting machine. It is responsible for driving the transmission rod 11 to move horizontally, and then realizes the stable extrusion and fixation of the cutting pipe 5 through the conical block 13 and the force plate 12. The connecting frame 15 is fixedly connected to the right side of the bracket 2. As a supporting and fixing component of the transmission structure 14, the worm gear 16 is movably connected to the right side of the connecting frame 15 through a bearing. The right end of the transmission rod 11 successively penetrates the connecting frame 15 and the worm gear 16 and extends to the right side of the worm gear 16, so that the worm gear 16 can rotate freely around its axis. At the same time, the transmission rod 11 can move horizontally in the internal thread of the worm gear 16. The worm gear 16 and the transmission rod 11 are threadedly connected. This connection method not only provides a stable transmission effect, but also ensures the accuracy and stability of the transmission rod 11 during movement. When the worm gear 16 rotates, the thread on its inner surface will The worm 18 interacts with the threads on the surface of the transmission rod 11, thereby driving the transmission rod 11 to move horizontally. The worm 18 is fixedly connected to the output end of the transmission motor 17 and is located on one side of the worm wheel 16. The worm 18 and the worm wheel 16 are meshed with each other, forming an efficient transmission method. When the transmission motor 17 drives the worm 18 to rotate, the worm 18 will drive the worm wheel 16 to rotate synchronously. The transmission motor 17 serves as the power source of the transmission structure 14 and is responsible for providing stable rotational power. When the transmission motor 17 is started, its output end will drive the worm 18 to rotate. Since the worm 18 and the worm wheel 16 are meshed with each other, the rotation of the worm 18 will drive the worm wheel 16 to rotate synchronously. As the worm wheel 16 rotates, the threads on its inner surface will interact with the threads on the surface of the transmission rod 11, thereby driving the transmission rod 11 to move horizontally. This transmission method not only has efficient transmission efficiency, but also can achieve precise displacement control.

[0049] As a technical optimization solution of the present invention, through the transmission mode of the worm gear 16 and the worm gear 18, the transmission motor 17 can accurately control the horizontal movement distance and speed of the transmission rod 11. This design ensures the precise positioning and stable movement of the splint 9. At the same time, the self-locking characteristics of the worm gear 16 and the worm gear 18 also increase the safety of the equipment.

[0050] refer to Figure 6The rotating structure 3 includes a driven wheel 19 movably connected to the left side of the bracket 2 through a bearing, and a rotating wheel 20 is fixedly connected to the left side of the driven wheel 19. The rotating wheel 20 and the driven wheel 19 are both sleeved on the surface of the transmission rod 11 and movably connected to the transmission rod 11. The connecting block 8 is fixedly connected to the left side of the rotating wheel 20. When the rotating wheel 20 rotates, the connecting block 8 can be used to drive the clamping plate 9 to rotate synchronously around the transmission rod 11 and the conical block 13 and ensure that the conical block 13 squeezes and positions the force plate 12. A linkage structure 21 is provided on the right side of the bracket 2. The linkage structure 21 can utilize the power of the transmission rod 11 and drive the rotating wheel 20 to rotate.

[0051] As a technical optimization solution of the present invention, the design of the driven wheel 19 and the rotating wheel 20 allows the power of the transmission rod 11 to be transmitted to the connecting block 8 and the clamping plate 9, thereby driving the pipe to rotate. This rotating structure 3 not only realizes the continuous cutting of the pipe, but also ensures the uniformity and smoothness of the cutting surface.

[0052] refer to Figure 6 The linkage structure 21 includes a vertical plate 22 fixedly connected to the right side of the bracket 2, and a connecting rod 23 is movably connected to the interior of the vertical plate 22 through a bearing. The left end of the connecting rod 23 passes through the left side of the bracket 2 and is fixedly connected to a driving wheel 24. The driving wheel 24 is located at the bottom of the driven wheel 19 and meshes with the driven wheel 19. The vertical plate 22 is L-shaped and the end away from the bracket 2 and the surface of the connecting rod 23 are both installed with a bevel gear 25, and the bevel gears 25 are meshed with each other. The bevel gears 25 on the surface of the vertical plate 22 are fixedly connected to the driving wheel 26 through a pin shaft, and a linkage plate 27 is fixedly connected to the surface of the transmission rod 11. The bottom of the linkage plate 27 is fixedly connected to a toothed plate 28 located at the top of the driving wheel 26, and the toothed plate 28 can mesh with the driving wheel 26 after the transmission rod 11 moves a certain distance to the right.

[0053] As a technical optimization solution of the present invention, through the cooperation of the bevel gear 25 and the driving wheel 26, the power of the transmission rod 11 is driven to rotate the rotating wheel 20, which fully utilizes the moving energy of the transmission rod 11, improves the overall efficiency of the equipment, and ensures the continuity and stability of the rotation of the pipe during the cutting process.

[0054] refer to Figure 7 Both ends of the right side of the bracket 2 are fixedly connected with guide rods 29, and the side of the guide rod 29 away from the bracket 2 is fixedly connected to the connecting frame 15, and the linkage plate 27 is sleeved on the surface of the guide rod 29 and slides with the guide rod 29.

[0055] As a technical optimization solution of the present invention, the design of the guide rod 29 provides a stable sliding track for the linkage plate 27, ensuring the stability and accuracy of the linkage plate 27 during movement, which not only improves the stability of the equipment, but also helps to extend the service life of the equipment.

[0056] refer to Figure 7 The adjustment structure 6 includes a movable block 30 fixedly connected to the right side of the bracket 2. The surface of the movable block 30 is movably connected to a rocker arm 31 through a pin shaft. The rocker arm 31 extends to the top of the cutting tube 5 away from the side of the movable block 30 and is interconnected with the laser emitting end 7. The rocker arm 31 can swing with the laser emitting end 7 around the pin shaft inside the movable block 30.

[0057] As a technical optimization solution of the present invention, through the connection between the rocker arm 31 and the movable block 30, the laser emitting end 7 can flexibly adjust the position to meet the cutting requirements of different pipes, thereby increasing the flexibility of the equipment and making the cutting process more precise and efficient.

[0058] refer to Figure 7 A sleeve plate 32 is fixedly connected to the side of the swing rod 31 close to the movable block 30, and the side of the sleeve plate 32 away from the swing rod 31 extends to the top of the linkage plate 27. A push rod 33 is fixedly connected to the top of the linkage plate 27, and the push rod 33 extends to the inside of the sleeve plate 32 away from the linkage rod. The sleeve plate 32 and the push rod 33 are slidably connected. The shape of the sleeve plate 32 is a bent state and the bending angle is an obtuse angle. When the push rod 33 moves to the bent part of the sleeve plate 32, it can push the sleeve plate 32 to swing. When the push rod 33 moves to the outside of the bent part of the sleeve plate 32, it can keep the sleeve plate 32 still.

[0059] As a technical optimization solution of the present invention, through the sliding connection design between the sleeve plate 32 and the push rod 33, the push rod 33 can push the sleeve plate 32 to swing when it moves to the bending part of the sleeve plate 32, thereby driving the laser emitting end 7 to adjust its position, thereby realizing automatic adjustment of the laser emitting end 7, reducing manual intervention and improving work efficiency.

[0060] refer to Figure 7 The top of the rocker arm 31 is fixedly connected to a frame 34, the interior of the frame 34 is movably connected to a reciprocating screw 35 through a bearing, the surface of the reciprocating screw 35 is threadedly connected to a screw sleeve 36, and the laser emitting end 7 is fixedly connected to the bottom of the screw sleeve 36. When the reciprocating screw 35 rotates, the screw sleeve 36 can be driven by the thread to carry the laser emitting end 7 to move horizontally.

[0061] As a technical optimization solution of the present invention, through the threaded connection between the screw and the screw sleeve 36, the laser emitting end 7 can move horizontally, further increasing the flexibility of the cutting position, making the cutting process more precise, and being able to perform continuous interval cutting on the cutting pipeline.

[0062] refer to Figure 7The right end of the reciprocating screw 35 passes through the right side of the frame 34 and is fixedly connected to a ratchet 37. A support plate 38 is fixedly connected to the surface of the bracket 2. The side of the support plate 38 away from the bracket 2 is movably connected to a pawl assembly 39 located on one side of the ratchet 37 through a pin shaft, and the pawl and the ratchet 37 mesh with each other.

[0063] As a technical optimization solution of the present invention, the design of the ratchet 37 and the pawl assembly 39 ensures the unidirectionality of the screw during rotation, preventing the laser emitting end 7 from accidentally moving during the cutting process. This safety locking mechanism improves the reliability and safety of the equipment, and can automatically drive the screw sleeve 36 to change the cutting position during the swing of the pendulum 31, thereby meeting the quantitative cutting requirements of the equipment.

[0064] The working principle and use process of the present invention are as follows: the metal pipe to be cut is first placed in an appropriate position and sleeved on the surface of multiple clamps 9, waiting to be fixed, and the transmission motor 17 starts to work, and its output end drives the worm 18 to rotate, and the worm 18 and the worm wheel 16 are meshed with each other. The rotation of the worm 18 drives the worm wheel 16 to rotate synchronously. Since the inner surface of the worm wheel 16 has threads, and the transmission rod 11 is threadedly connected with the worm wheel 16, the rotation of the worm wheel 16 causes the transmission rod 11 to move horizontally. As the left end of the transmission rod 11 moves to the left, the conical block 13 thereon gradually contacts and squeezes the force-bearing plate 12 of each clamp 9. Since the left end of the force-bearing plate 12 is set to be inclined to the outside, the conical block 13 The extrusion causes the force-bearing plate 12 and the connected clamping plate 9 to swing outward until the clamping plate 9 is tightly fitted and fixed to the inner surface of the cutting pipe 5. As the transmission rod 11 continues to move, the push rod 33 on the linkage plate 27 begins to contact the sleeve plate 32. At this time, the push rod 33 enters the bent portion of the sleeve plate 32. Therefore, the sleeve plate 32 can swing with the frame 34 using the swing rod 31 and carry the laser emitting end 7 to the top of the cutting pipeline. When the laser emitting end 7 and the cutting pipeline are parallel to each other, the continuously moving push rod 33 breaks away from the bent portion of the sleeve plate 32 and enters the subsequent horizontal portion of the sleeve plate 32. The sleeve plate 32 and the connected swing rod 31 that are out of the extrusion state remain stationary. At this time, the laser emitting end 7 is moved to the top of the cutting pipeline. The light emitting end 7 is connected to the reciprocating screw 35 through the screw sleeve 36 and remains in the initial position, waiting for further adjustment. When the transmission rod 11 continues to move to the right for a distance, the toothed plate 28 on the linkage plate 27 meshes with the driving wheel 26. The driving wheel 26 is driven by the bevel gear 25 to drive the connecting rod 23 and the driving wheel 24 to rotate. The driving wheel 24 meshes with the driven wheel 19. The rotation of the driven wheel 19 drives the rotating wheel 20 and the connecting block 8 to rotate synchronously. Since the connecting block 8 is fixedly connected to the clamping plate 9, the clamping plate 9 and the cutting pipe 5 also rotate accordingly. During the rotation, the laser emitting end 7 starts to emit laser to cut the rotating cutting pipe 5. When the laser reflecting end When a single cutting is completed, the laser emitting end 7 stops emitting laser, the transmission motor 17 runs in the reverse direction and the linkage plate 27 carries the push rod 33 to move to the bending part of the sleeve plate 32 again. The sleeve plate 32, which is squeezed again, resets and swings, and the ratchet 37 on its surface is out of contact with the pawl. When the swing rod 31 carries the frame 34 to swing to a certain angle, the swing rod 31 resets, and the ratchet 37 on the surface of the frame 34 contacts the pawl. The pawl squeezes the ratchet 37, causing the reciprocating screw 35 connected to the ratchet 37 to rotate. The reciprocating screw 35 uses the thread to push the screw sleeve 36 to carry the laser emitting end 7 to move horizontally, thereby achieving the effect of changing the cutting position of the laser emitting end 7 and meeting the continuous cutting requirements.

[0065] To sum up: the metal pipe processing laser cutting machine integrates the functions of fixing the workpiece, adjusting the cutting position, rotating the workpiece, and can realize linkage work. This integrated design improves work efficiency, reduces the equipment footprint, and ensures the convenience and accuracy of operation.
