Description

Technical Field

[0001] This invention relates to the field of laser cutting machine technology, specifically to a CNC laser cutting machine for valve processing. Background Technology

[0002] Valves are crucial control components in fluid systems, used for guiding, cutting off, regulating flow, and preventing backflow. They are widely used in energy, chemical, shipbuilding, and aerospace industries. In industrial valve manufacturing, steel pipes, especially seamless steel pipes, are often used as raw materials for the valve bodies of some ball valves and gate valves. Seamless steel pipes are particularly valuable due to their excellent strength and sealing properties. Through cutting and welding, flanges can be easily welded to both ends or threaded interfaces can be machined for connecting pipelines. A hole can also be drilled in the middle of the steel pipe to accommodate the installation requirements of the valve stem and valve core. However, the cutting process generates metal fragments and debris, which remain inside the cut pipe. When transferring the cut pipe, these debris easily scatters, polluting the working environment, increasing cleaning difficulty, and potentially contaminating other processing stages, affecting equipment operation. Currently, manual cleaning of the debris inside the steel pipe is generally required, a cumbersome, time-consuming, and labor-intensive process that significantly reduces production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a CNC laser cutting machine for valve processing, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a CNC laser cutting machine for valve processing, comprising a mounting base plate, a conveying device and a laser cutting device mounted on the mounting base plate, and further comprising:

[0005] A support plate is fixed to a mounting base plate, and a rotating support block is rotatably mounted on the support plate. A connecting pipe is connected to the rotating support block.

[0006] A movable component, mounted on a rotating support block, is used to drive the cutting pipe to connect with the connecting pipe.

[0007] The components are mounted on the rotating support block and include a movable scraper that can extend into the cutting tube and a drive connector that drives the movable scraper to adhere to the inner wall of the cutting tube.

[0008] The combined drive assembly, mounted on the support plate, is used to drive the rotating support block to rotate so that the cutting tube changes from a horizontal state to a vertical state, and simultaneously drives the moving scraper to rotate and scrape inside the cutting tube.

[0009] Preferably, the moving component includes a sliding connecting plate slidably mounted on the rotating support block, a power component for driving the sliding connecting plate to move, and a clamping component mounted on the sliding connecting plate.

[0010] Preferably, the driving connector includes a movable fixed plate fixedly installed at the lower end of the sliding connecting plate and a sliding long plate slidably connected to the rotating support block. The movable fixed plate can abut against the sliding long plate to drive the sliding long plate to move.

[0011] Preferably, a connecting plate is fixed to one end of the sliding plate, and a return spring is sleeved on the sliding plate. The two ends of the return spring are respectively fixedly connected to the connecting plate and the rotating support block.

[0012] Preferably, the drive connector further includes a support column fixedly installed inside the docking connecting pipe, a short support column rotatably installed inside the rotating support block, and a rotating protrusion rotatably installed on the connecting plate. A long support column is rotatably connected inside the support column. A sliding rectangular plate is fixedly connected to one end of the rotating protrusion. The end of the sliding rectangular plate away from the rotating protrusion slides through the short support column and the long support column.

[0013] Preferably, a first hinge plate is hinged to the sliding rectangular plate, and a second hinge plate is hinged to the supporting column. The end of the first hinge plate away from the sliding rectangular plate is hinged to the movable scraper.

[0014] Preferably, the second hinge plate is hinged to the movable scraper at the end away from the supporting long column, and the sliding mating surfaces of the supporting short column, the supporting long column, and the sliding rectangular plate are all rectangular cross sections.

[0015] Preferably, the combined drive assembly includes a mounting worm gear fixedly mounted on a support column and a fixed gear ring fixedly mounted on a support plate. A mating gear meshes on the fixed gear ring, and a mounting worm is fixedly connected to one end of the mating gear. A mounting worm gear meshes on the mounting worm.

[0016] Preferably, a rotating support column is rotatably mounted on the support plate, a sliding toothed plate is slidably mounted on the support plate, a connecting gear is fixedly mounted on the rotating support column, and the sliding toothed plate meshes with the connecting gear.

[0017] Preferably, when the rotating support block flips, the mating gear revolves around the fixed gear ring and rotates on its own axis, transmitting power to the moving scraper through the mounting worm and mounting worm wheel.

[0018] Preferably, the rotating support block has an internal connecting cavity, the docking connecting pipe is connected to the internal connecting cavity, the internal connecting cavity is also connected to a rotating connecting pipe, the rotating connecting pipe is rotatably mounted on the support plate, and one end of the rotating connecting pipe is connected to an external vacuum cleaner through a rotary joint.

[0019] Preferably, the power component includes a threaded rod rotatably mounted on a rotating support block, a fixing block threadedly connected to the threaded rod, the fixing block being fixedly mounted on a sliding connecting plate, and the clamping component including a support frame plate fixedly mounted on the sliding connecting plate, an electric push rod fixedly mounted on the support frame plate, and a clamping plate fixedly mounted on the output end of the electric push rod.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By coordinating the moving components and mating components, the automatic docking of the cutting tube and the connecting tube is achieved. The rotation of the threaded rod drives the sliding connecting plate to move, bringing the cutting tube closer to the connecting tube. During this process, the moving fixed plate at the lower end of the sliding connecting plate pushes the sliding long plate to slide, which in turn drives the connecting plate, the rotating protrusion, and the sliding square long plate to move. Finally, the first hinge plate and the second hinge plate drive the moving scraper to fit against the inner wall of the cutting tube, ensuring docking accuracy and stability and improving processing efficiency.

[0022] 2. By incorporating a cooperating component and a combined drive component, the inner wall of the cutting tube is scraped synchronously during its rotation. When the electric telescopic rod pushes the sliding toothed plate to move, the connecting gear drives the rotating support column to rotate, causing the rotating support block to change from a horizontal to a vertical state. At this time, the fixed toothed ring meshes with the cooperating gear, causing the cooperating gear to rotate on its own axis during its revolution around the fixed toothed ring. Through the transmission of the worm gear and worm wheel, the short and long support columns are driven to rotate, thereby causing the moving scraper to rotate and scrape inside the cutting tube. Simultaneously, the rotating connecting pipe is connected to a vacuum cleaner through a rotary joint. When the cutting tube is in a vertical state, the residue is discharged through the internal connecting cavity using the combined action of gravity and suction, achieving automated cleaning.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 13This invention provides a technical solution: a CNC laser cutting machine for valve processing, comprising a mounting base plate 1, a conveying device 2 and a laser cutting device 3 mounted on the mounting base plate 1, and further comprising: a support plate 4 fixed to the mounting base plate 1, a rotating support block 5 rotatably mounted on the support plate 4, and a connecting pipe 8 connected to the rotating support block 5; a moving component 6 mounted on the rotating support block 5 for driving the cutting pipe 11 to connect with the connecting pipe 8; and a mating component 7 mounted on the rotating support block 5, including a movable scraper 710 that can extend into the cutting pipe 11. The moving scraper 710 is attached to the inner wall of the cutting tube 11 by a drive connector; the combined drive assembly 9, mounted on the support plate 4, drives the rotating support block 5 to rotate so that the cutting tube 11 changes from a horizontal state to a vertical state, and simultaneously drives the moving scraper 710 to rotate and scrape inside the cutting tube 11. Through the cooperation of the moving assembly 6 and the mating assembly 7, the automatic docking of the cutting tube 11 and the connecting tube 8 is realized. The rotation of the threaded rod 61 drives the sliding connecting plate 63 to move, so that the cutting tube 11 moves closer to the connecting tube 8. During this process, the sliding connecting plate 63... The lower movable fixed plate 71 pushes the sliding long plate 72 to slide, driving the connecting plate 74, rotating protrusion 75, and sliding square long plate 76 to move. Finally, the first hinge plate 711 and the second hinge plate 712 drive the moving scraper 710 to fit against the inner wall of the cutting tube 11, ensuring docking accuracy and stability and improving processing efficiency. By setting the mating component 7 and the combined drive component 9, the inner wall of the cutting tube 11 is scraped synchronously during the flipping process. When the electric telescopic rod 97 pushes the sliding toothed plate 91 to move, the connecting gear 92 drives the rotating support column 12 to rotate, causing the rotation... When the support block 5 changes from a horizontal to a vertical position, the fixed gear ring 93 meshes with the mating gear 94, causing the mating gear 94 to revolve around the fixed gear ring 93 and rotate on its own axis. Through the transmission of the mounting worm 95 and the mounting worm wheel 96, the support short column 77 and the support long column 78 are driven to rotate, thereby causing the moving scraper 710 to rotate and scrape inside the cutting tube 11. At the same time, the rotating connecting tube 13 is connected to the vacuuming equipment through the rotary joint. When the cutting tube 11 is in a vertical position, the residue is discharged through the internal connecting cavity 14 by the combined action of gravity and suction, thus realizing automated cleaning.

[0039] like Figure 6 as well as Figure 7As shown, the moving component 6 includes a sliding connecting plate 63 slidably mounted on the rotating support block 5, a power component for driving the sliding connecting plate 63 to move, and a clamping component mounted on the sliding connecting plate 63. The power component includes a threaded rod 61 rotatably mounted on the rotating support block 5, with a fixing block 62 threadedly connected to the threaded rod 61. The fixing block 62 is fixedly mounted on the sliding connecting plate 63. The clamping component includes a support frame plate 64 fixedly mounted on the sliding connecting plate 63, with an electric push rod 65 fixedly mounted on the support frame plate 64. The output end of the electric push rod 65 is fixedly mounted with... The clamping plate 66 and the threaded rod 61 are driven by a drive motor. Before cutting, the electric push rod 65 on the support frame plate 64 drives the clamping plate 66 to clamp the steel pipe surface. After cutting, the threaded rod 61 is driven to rotate by the drive motor. The threaded rod 61 is threadedly connected to the fixing block 62. The rotation of the threaded rod 61 drives the fixing block 62 to move. The fixing block 62 drives the sliding connecting plate 63 to slide on the rotating support block 5, thereby driving the cutting tube 11 to move. The moving scraper 710 extends into the cutting tube 11, and the cutting tube 11 connects with the connecting pipe 8.

[0040] like Figure 7 and Figure 8 As shown, the driving connector includes a movable fixed plate 71 fixedly installed at the lower end of the sliding connecting plate 63 and a sliding long plate 72 slidably connected to the rotating support block 5. The movable fixed plate 71 can abut against the sliding long plate 72 to drive the sliding long plate 72 to move. A connecting plate 74 is fixed to one end of the sliding long plate 72, and a return spring 73 is sleeved on the sliding long plate 72. The two ends of the return spring 73 are respectively fixedly connected to the connecting plate 74 and the rotating support block 5. The movable fixed plate 71 on the sliding connecting plate 63 contacts the sliding long plate 72 and drives the sliding long plate 72 to move on the rotating support block 5. The sliding plate 72 drives the connecting plate 74 to move away from the rotating support block 5. The return spring 73 is stretched. The connecting plate 74 drives the sliding square plate 76 to slide inside the supporting short column 77 and the supporting long column 78 through the rotating protrusion 75. The supporting long column 78 cannot slide under the restriction of the supporting column 79. When the sliding square plate 76 slides inside the supporting long column 78, it drives the moving scraper 710 to move away from the supporting long column 78 through the first hinge plate 711 and the second hinge plate 712 and contacts the inner wall of the cutting tube 11.

[0041] like Figures 7 to 9As shown, the drive connector also includes a support column 79 fixedly installed inside the docking connecting pipe 8, a short support column 77 rotatably installed inside the rotating support block 5, and a rotating protruding column 75 rotatably installed on the connecting plate 74. A ring is fixedly installed on the short support column 77. A long support column 78 is rotatably connected inside the support column 79. A ring is fixedly installed on the long support column 78. A sliding rectangular plate 76 is fixedly connected to one end of the rotating protruding column 75. The end of the sliding rectangular plate 76 away from the rotating protruding column 75 slides through the short support column 77 and the long support column 78. A first hinge plate 711 is hinged on the sliding rectangular plate 76, and a second hinge plate is hinged on the long support column 78. The connecting plate 712 has a first hinge plate 711 hinged at the end away from the sliding rectangular plate 76 to the movable scraper 710, and a second hinge plate 712 hinged at the end away from the supporting column 78 to the movable scraper 710. The sliding mating surfaces of the supporting short column 77, the supporting long column 78, and the sliding rectangular plate 76 are all rectangular cross sections. The movable fixed plate 71 at the lower end of the sliding connecting plate 63 pushes the sliding long plate 72 to slide, which drives the connecting plate 74, the rotating protrusion 75, and the sliding rectangular plate 76 to move. Finally, the first hinge plate 711 and the second hinge plate 712 drive the movable scraper 710 to fit against the inner wall of the cutting tube 11, ensuring docking accuracy and stability and improving processing efficiency.

[0042] like Figure 10 and Figure 13As shown, the combined drive assembly 9 includes a mounting worm gear 96 fixedly mounted on a support short column 77 and a fixed gear ring 93 fixedly mounted on a support plate 4. A mating gear 94 meshes on the fixed gear ring 93, and a mounting worm 95 is fixedly connected to one end of the mating gear 94. The mounting worm gear 96 meshes on the mounting worm 95. A rotating support column 12 is rotatably mounted on the support plate 4, and a sliding gear plate 91 is slidably mounted on the support plate 4. A connecting gear 92 is fixedly mounted on the rotating support column 12, and the sliding gear plate 91... 1. Engages with connecting gear 92. When the rotating support block 5 flips, the cooperating gear 94 revolves around the fixed gear ring 93 and rotates on its own axis. Power is transmitted to the movable scraper 710 through the mounting worm 95 and mounting worm wheel 96. The electric telescopic rod 97 is fixedly installed on the support plate 4. A sliding toothed plate 91 is fixedly installed at the output end of the electric telescopic rod 97. When the vacuum cleaner and the electric telescopic rod 97 are started, the electric telescopic rod 97 extends, causing the sliding toothed plate 91 to slide on the support plate 4. The sliding toothed plate 91 drives the connecting gear 92 to rotate. The connecting gear 92 drives the rotating support block 5 to rotate via the rotating support column 12, causing the cutting tube 11 on the first hinge plate 711 to rotate from a horizontal state to a vertical state. During this process, since the fixed gear ring 93 is in a fixed state, it meshes with the mating gear 94. The mating gear 94 rotates on its own axis while revolving around the rotating support column 12. The mating gear 94 drives the mounting worm 95 to rotate, which in turn drives the mounting worm wheel 96 to rotate. The mounting worm wheel 96 then drives the supporting short column 77 to rotate. The rotation of the short support column 77 causes the sliding rectangular plate 76 inside it to rotate. The sliding rectangular plate 76 causes the long support column 78 to rotate within the support column 79, which in turn causes the movable scraper 710 to rotate. This causes the movable scraper 710 to scrape and clean the inner wall of the cutting tube 11. As the cutting tube 11 rotates from a horizontal state to a vertical state, the movable scraper 710 continuously scrapes the inner wall of the cutting tube 11. With the assistance of the vacuuming equipment, it is easy to remove and collect the residue inside the cutting tube 11.

[0043] like Figure 9 and Figure 10 As shown, the rotating support block 5 has an internal connecting cavity 14, and the connecting pipe 8 is connected to the internal connecting cavity 14. The internal connecting cavity 14 is also connected to a rotating connecting pipe 13, which is rotatably mounted on the support plate 4. One end of the rotating connecting pipe 13 is connected to an external vacuum cleaner through a rotary joint. The conveying device 2 and the laser cutting device 3 are both mature existing technologies and will not be described in detail here.

[0044] In actual use, the steel pipe is conveyed by the conveying device 2 and cut by the laser cutting device 3. Before cutting, the electric push rod 65 on the support plate 64 drives the clamping plate 66 to clamp the surface of the steel pipe. After cutting, the threaded rod 61 is driven to rotate by the drive motor. The threaded rod 61 is threadedly connected to the fixed block 62. The rotation of the threaded rod 61 drives the fixed block 62 to move. The fixed block 62 drives the sliding connecting plate 63 to slide on the rotating support block 5, thereby driving the cutting tube 11 to move. The moving scraper 710 extends into the cutting tube 11, and the cutting tube 11 connects with the connecting pipe 8. During this process, the sliding... The movable fixed plate 71 on the connecting plate 63 contacts the sliding long plate 72 and drives the sliding long plate 72 to slide on the rotating support block 5. The sliding long plate 72 drives the connecting plate 74 to move away from the rotating support block 5. The return spring 73 is stretched. The connecting plate 74 drives the sliding square long plate 76 to slide inside the supporting short column 77 and the supporting long column 78 through the rotating protrusion 75. The supporting long column 78 cannot slide under the restriction of the supporting column body 79. When the sliding square long plate 76 slides inside the supporting long column 78, it drives the movable scraper 710 to move away from the supporting long column 78 through the first hinge plate 711 and the second hinge plate 712. The device moves and contacts the inner wall of the cutting tube 11; the vacuum cleaner and electric telescopic rod 97 are activated, the electric telescopic rod 97 extends and drives the sliding toothed plate 91 to slide on the support plate 4, the sliding toothed plate 91 drives the connecting gear 92 to rotate, the connecting gear 92 drives the rotating support block 5 to rotate through the rotating support column 12, so that the cutting tube 11 on the first hinge plate 711 turns from a horizontal state to a vertical state. During this process, since the fixed toothed ring 93 is in a fixed state, the fixed toothed ring 93 meshes with the mating gear 94. The mating gear 94 rotates on its own axis during its revolution around the rotating support column 12, and the mating gear 94 drives the mounting worm gear 95. The rotation of the worm gear 95 drives the worm wheel 96 to rotate, which in turn drives the support column 77 to rotate. The support column 77 drives the sliding rectangular plate 76 on its inner side to rotate, which in turn drives the support column 78 to rotate within the support column 79. This, in turn, drives the moving scraper 710 to rotate, causing the moving scraper 710 to scrape and clean the inner wall of the cutting tube 11. As the cutting tube 11 rotates from a horizontal to a vertical position, the moving scraper 710 continuously scrapes the inner wall of the cutting tube 11 to prevent residue. At the same time, with the cooperation of the vacuuming equipment, it is convenient to remove and collect the residue inside the cutting tube 11.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
