Description

Technical Field

[0001] This invention is a dustproof and protective pneumatic chuck for pipe cutting machines, belonging to the field of pneumatic chucks. Background Technology

[0002] Laser cutting technology is a highly efficient and high-capacity technology. The advantages of laser tube cutting machines are: high cutting precision, high dimensional accuracy, smooth and burr-free cuts, and low wear; minimal heat-affected zone in the laser cutting area, no thermal deformation, and good consistency of parts processing; high cutting efficiency, enabling large-scale batch production. The adoption of a digital control system, through program control, makes the tube cutting machine more flexible and precise, thus requiring more stable control over processing accuracy.

[0003] Currently, the precision of pneumatic four-jaw chucks on the market cannot meet the precision required for production. This is due to the shortcomings in the structure and performance of pneumatic chucks. Dust prevention is an important factor. Due to the processing environment of laser cutting, dust is generated at a high rate and easily adheres to the chuck body. Not only is the outside covered with dust, but dust that can penetrate into the chuck body will increase the frictional resistance of the chuck's clamping movement, making clamping difficult. Long-term friction will cause insufficient transmission precision, often causing the pneumatic chuck to malfunction. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a dustproof and protective pneumatic chuck for pipe cutting machines.

[0015] Furthermore, the bottom of the cleaning box opening is provided with a scraping blade that cooperates with the claw, and the outer surface of the extrusion roller is provided with a layer of rubber pad.

[0016] The beneficial effects of the present invention

[0017] The dust removal mechanism is designed to allow for two-stage adhesive bonding of the outer surface of the gripper claws. Between the two adhesive bonding ends, a cleaning process is also performed, thus enabling the cleaning of the outer surface of the gripper claws.

[0018] Through the design of the bonding component, a motor drives a take-up roller to rotate, which in turn winds up the tape. This causes the tape to move along the trajectory formed by the guide roller and the extrusion roller, allowing for two-stage adhesion to the outer surface of the gripper. The tape after the first stage of adhesion passes back to the extrusion roller. When the tape containing metal particles is pressed against the outer surface of the extrusion roller, a rubber pad is added to the outer surface of the extrusion roller. This ensures that the extrusion roller and the outer surface of the tape containing metal particles are in elastic contact. This allows the extrusion roller to compress the metal particles, making them tightly bonded to the tape's adhesive surface. At the same time, the rubber pad increases the friction with the metal particles, preventing them from falling off and ensuring that the metal particles are firmly bonded to the tape's adhesive surface.

[0019] By adjusting the design of the components, when the bonding component is started, motor two is started first to drive the active bevel gear to rotate. The active bevel gear drives bevel gear two to rotate through bevel gear three and the rotating rod. Bevel gear two drives cam to rotate through bevel gear one and the rotating shaft. The rotation of the cam pushes the fixed frame to move horizontally through the convex surface. The horizontal movement of the fixed frame pushes the elastic extrusion head to move linearly through the moving plate. The elastic extrusion head pushes the adhesive surface of the tape to contact the outer surface of the claw through elastic deformation, thereby cleaning the outer surface of the claw. At the same time, the tape that has been adhered will be wound up by the take-up roller.

[0020] Through the design of the sweeping component, after the gripper passes through the first stage of the adhesive component, the sweeping component can sweep and clean the gripper. Specifically, starting motor three drives the drive gear to rotate, which in turn drives an external gear ring and an intermediate gear to rotate. The intermediate gear drives another external gear ring to rotate, which in turn drives the two external gear rings to rotate synchronously with the movable cylinders. The two movable cylinders rotate in opposite directions, which in turn drives several traveling bevel gears to rotate. The traveling bevel gears travel on the fixed bevel gears while rotating, which in turn drives the rotating shaft to rotate on the movable cylinder. This causes the rotating movable cylinder to drive several elastic cleaning heads to contact the outer surface of the gripper. The rotating elastic cleaning heads can sweep away the particles adhering to the gripper through rotational friction. The several sets of elastic cleaning heads on the two movable cylinders are staggered to completely remove the particles.

[0021] By incorporating a negative pressure fan, ventilation duct, suction pipe three, suction pipe two, and suction pipe one, particles located inside the cleaning box, in the groove, and in the receiving slot can all be adsorbed onto the outside of the shell, reducing the possibility of particles accumulating inside the shell.

[0022] By adding a rubber pad to the outer surface of the extrusion roller, the two are in elastic contact when the extrusion roller is pressed together with the outer surface of the tape containing metal particles. This allows the extrusion roller to press the metal particles together so that the metal particles are tightly bonded to the tape surface. At the same time, the rubber pad can also increase the friction with the metal particles, preventing the metal particles from falling off and ensuring that the metal particles are firmly bonded to the tape surface.

[0023] By using a design where the two moving cylinders rotate in opposite directions, the particles swept up by the two cylinders can be gathered together, preventing the particles from splashing out. Instead, the particles are gathered between the two cylinders, reducing the possibility of splashing and allowing them to fall steadily into the collection tank. Attached Figure Description

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example 1, please refer to Figures 1-9. This invention provides a dustproof pneumatic chuck for a pipe cutting machine. The dustproof pneumatic chuck includes a housing 1. A processing port 2 is provided in the middle of the housing 1. A plurality of receiving grooves 3 are evenly distributed on the inner wall of the processing port 2. A chuck 5 is slidably connected within each receiving groove 3. A plurality of sliders 6 are provided on both sides of the outer surface of each chuck 5. Sliding grooves 7 that cooperate with the sliders 6 are provided on the inner walls of both sides of the receiving groove 3. The inner wall at the opening of the receiving groove 3 is provided with a groove that cooperates with the chuck 5. The scraper blade 8, the claw 5 is connected to the drive assembly, the storage slot 3 is provided with dust removal mechanisms on both sides, the outer surface of the housing 1 is provided with a negative pressure fan 48, and the housing 1 is provided with a number of ventilation pipes connected and communicating with the negative pressure fan 48. The ventilation pipes are connected to the dust removal mechanism. Through the design of the dust removal mechanism, the outer surface of the claw 5 can be glued and adhered in two sections, and cleaning is also performed between the two glued and adhered ends, so that the outer surface of the claw 5 can be cleaned.

[0037] In the second embodiment, referring to Figure 2, the driving component is a cylinder 4, which is connected and fixed to the storage groove 3. The driving component here is not only the cylinder 4, but also a conventional driving component in the prior art, all of which are within the protection scope of the driving component in this application, such as a driving component composed of a gear and a rack and pinion plate, and a driving component composed of a connecting rod, etc., which are all conventional driving components in the prior art.

[0038] Example 3, referring to Figures 4-9, the dust removal mechanism includes a receiving groove 9 formed on the inner wall of the receiving groove 3. Several suction pipes 10 are provided on the bottom side wall of the receiving groove 9. The receiving groove 9 contains an adhesive assembly, an adjustment assembly, and a sweeping assembly. The adhesive assembly includes a placement roller 11 and a take-up roller 12 located on both sides inside the receiving groove 9. One end of the placement roller 11 is movably connected to the inner wall of the receiving groove 9, and an adhesive tape 13 is placed on the placement roller 11. The other end of the adhesive tape 13 is connected to the outer surface of the take-up roller 12. The take-up roller 12 is connected to a motor 33, which is fixedly connected to the inner wall of the receiving groove 9. Two sets of guide rollers 14 are symmetrically arranged at the opening of the receiving groove 9. Squeeze rollers 15, which cooperate with the adhesive tape 13, are symmetrically arranged inside the receiving groove 9. The squeeze rollers 15 are movably connected to a support shaft 16, which is fixed to one side of the inner wall of the receiving groove 9. The inner wall of the receiving groove 9 is located on the inner wall of the receiving groove 3. A groove 17 is provided on the outer side of the support shaft 16, and several suction pipes 18 are provided inside the groove 17. Through the design of the bonding component, the take-up roller 12 can be driven by the motor 33 to rotate. The take-up roller 12 winds up the tape 13, so that the tape 13 moves along the trajectory formed by the guide roller 14 and the extrusion roller 15, thereby adhering to the outer surface of the claw 5 in two stages. After the first stage of adhesion, the tape 13 passes back to the extrusion roller 15. When the tape 13 with metal particles is squeezed together with the outer surface of the extrusion roller 15, a rubber pad is added to the outer surface of the extrusion roller 15. When the extrusion roller 15 and the outer surface of the tape 13 with metal particles are squeezed together, the two are in elastic contact. This allows the extrusion roller 15 to squeeze the metal particles so that the metal particles are tightly bonded to the adhesive surface of the tape 13. At the same time, the rubber pad can also increase the friction with the metal particles to prevent the metal particles from falling off, so that the metal particles can be firmly bonded to the adhesive surface of the tape 13.

[0039] Example 4, referring to Figures 5-6, the adjustment assembly includes a fixed plate 19 fixed to the inner wall of the receiving groove 9, a movable plate 20 slidably connected to the fixed plate 19, an elastic compression head 21 fixed to the side of the movable plate 20 near the opening of the receiving groove 9, a fixed frame 22 fixed to the other end of the movable plate 20, and a spring 25 sleeved on the outer surface of the movable plate 20 between the fixed frame 22 and the fixed plate 19. The adjustment assembly also includes an inner cavity I formed in the inner wall of the housing 1, a rotating shaft 23 movable on one side wall of the inner cavity, one end of the rotating shaft 23 penetrating into the receiving groove 9 and connected and fixed to a cam 24, the outer surface of the cam 24 pressing against the outer surface of the fixed frame 22, a bevel gear 26 fixed to one end of the rotating shaft 23 inside the inner cavity I, a motor 31 fixed to the middle of one side of the inner cavity I, an active bevel gear 32 provided at the side output end of the motor 31, and support columns 27 on both sides of the motor 31. 27 is fixedly connected to the inner wall of the inner cavity. A rotating rod 28 is movably connected to the supporting column 27. A bevel gear 29 and a bevel gear 30 are fixed to the two ends of the rotating rod 28, respectively. The bevel gear 29 meshes with the bevel gear 26, and the bevel gear 30 meshes with the driving bevel gear 32. Through the design of the adjustment component, when the bonding component is started, the motor 21 is started first to drive the driving bevel gear 32 to rotate. The driving bevel gear 32 meshes with the rotating rod 26 through the bevel gear 30. The moving rod 28 drives the second bevel gear 29 to rotate. The second bevel gear 29 drives the cam 24 to rotate through the first bevel gear 26 and the rotating shaft 23. The rotation of the cam 24 pushes the fixed frame 22 to move horizontally through the convex surface. The horizontal movement of the fixed frame 22 pushes the elastic extrusion head 21 to move linearly through the moving plate 20. The elastic extrusion head 21 pushes the adhesive surface of the tape 13 to contact the outer surface of the claw 5 through elastic deformation, thereby cleaning the outer surface of the claw 5. At the same time, the tape 13 that has been coated will be wound up by the take-up roller 12.

[0040] Example 5, see Figure 48, 9, The cleaning component is located in the cleaning box 34 in the middle of the opening of the receiving groove 9. Two movable cylinders 38 are movably connected to the inner wall of one side of the opening of the cleaning box 34. The inner wall of the cleaning box 34 has an inner cavity II. The two movable cylinders 38 are movably connected to the opening of the inner cavity II. An external gear ring 44 is fixed on the outer surface of one end of the movable cylinder 38 inside the inner cavity II. The outer surfaces of the two external gear rings 44 are respectively meshed with a drive gear 45 and an intermediate gear 46. The intermediate gear 46 meshes with the drive gear 45. 5 is connected to the output end of motor 347, which is fixed to the inner wall of the inner cavity 2. Several sets of rotating shafts 39 are movably connected at equal intervals on the outer surface of the movable cylinder 38 in the circumferential direction. An elastic cleaning head 40 is fixed to one end of each rotating shaft 39 located outside the movable cylinder 38, and a traveling bevel gear 41 is fixed to one end of each rotating shaft 39 located inside the movable cylinder 38. A fixed rod 42 is provided in the middle of the movable cylinder 38, and the end of the fixed rod 42 is connected and fixed to the inner wall of the inner cavity 2. Several fixed... The fixed bevel gear 43 meshes with the traveling bevel gear 41. Through the design of the sweeping component, after the claw 5 is first adhered to by the adhesive component, the sweeping component can clean the claw 5. Specifically, the motor 47 is started, driving the drive gear 45 to rotate. The drive gear 45 drives one external gear ring 44 and the intermediate gear 46 to rotate, and the intermediate gear 46 drives another external gear ring 44 to rotate. This allows the two external gear rings 44 to drive the movable cylinder 38 to rotate synchronously, and the rotation direction of the two movable cylinders 38 is... Conversely, the rotation of the movable cylinder 38 causes several traveling bevel gears 41 to rotate simultaneously. As the traveling bevel gears 41 rotate, they travel on the fixed bevel gear 43, which in turn causes the rotating shaft 39 to rotate on the movable cylinder 38. This causes the rotating movable cylinder 38 to drive several elastic cleaning heads 40 to contact the outer surface of the jaws 5. The rotating elastic cleaning heads 40 can remove the particles adhering to the jaws 5 through rotational friction. Furthermore, the several sets of elastic cleaning heads 40 on the two movable cylinders 38 are staggered, which can completely remove the particles.

[0041] In Example 6, referring to Figure 5, the bottom of the cleaning box 34 is provided with a collection groove 35, and the bottom of the collection groove 35 is provided with a suction pipe 36. The suction pipe 36, the suction pipe 2 18, and the suction pipe 10 are all connected to the ventilation duct. Through the design of the negative pressure fan 48, the ventilation duct, the suction pipe 36, the suction pipe 2 18, and the suction pipe 10, the particles located inside the cleaning box 34, the particles located in the groove 17, and the particles located inside the receiving groove 9 can all be adsorbed to the outside of the shell 1, reducing the possibility of particles accumulating inside the shell 1.

[0042] In Example 7, referring to Figure 5, the bottom of the opening of the cleaning box 34 is provided with a scraping blade 37 that cooperates with the claw 5, and the outer surface of the extrusion roller 15 is provided with a rubber pad. By adding a rubber pad to the outer surface of the extrusion roller 15, when the extrusion roller 15 is pressed together with the outer surface of the tape 13 containing metal particles, the two are in elastic contact. This allows the extrusion roller 15 to press the metal particles so that the metal particles are tightly bonded to the adhesive surface of the tape 13. At the same time, the rubber pad can also increase the friction with the metal particles, prevent the metal particles from falling off, and allow the metal particles to be firmly bonded to the adhesive surface 13.

[0043] In use, the four jaws 5 are moved by the drive assembly, so that the ends of the jaws 5 can penetrate into the processing port 2 to clamp the tube. (The drive assembly here is not only the cylinder 4, but also conventional drive assemblies in the prior art. They are all within the protection scope of the drive assembly in this application, such as drive assemblies composed of gears and racks and drive assemblies composed of connecting rods, etc., which are all conventional drive assemblies in the prior art.)

[0044] During the clamping process, the scraping blade 8 seals the gap between the inner wall of the storage slot 3 and the jaw 5, preventing dust particles from entering the storage slot 3. Simultaneously, as the jaw 5 moves back into the storage slot 3, the scraping blade 8 initially removes dust particles adhering to the outer surface of the jaw 5. However, some dust particles may still enter the storage slot 3. At this point, the dust removal mechanism can clean the dust particles from the outer surface of the jaw 5.

[0045] That is, the bonding assembly is started first, and motor 33 is started by the control switch. Motor 33 drives the take-up roller 12 to rotate, and the take-up roller 12 winds up the tape 13, so that the tape 13 moves along the track formed by the guide roller 14 and the extrusion roller 15, thereby allowing two-stage adhesion to the outer surface of the gripper 5. After the first stage of adhesion, the tape 13 passes back to the extrusion roller 15. When the tape 13 with metal particles is pressed together with the outer surface of the extrusion roller 15, a rubber pad is added to the outer surface of the extrusion roller 15. When the extrusion roller 15 and the outer surface of the tape 13 with metal particles are pressed together, the two are in elastic contact. This allows the extrusion roller 15 to press the metal particles together, making the metal particles tightly bonded to the adhesive surface of the tape 13. At the same time, the rubber pad can also increase the friction with the metal particles, preventing the metal particles from falling off, so that the metal particles can be firmly bonded to the adhesive surface of the tape 13.

[0046] Furthermore, when the adjusting component is not activated, there is a gap between the horizontal position of the tape 13 and the opening of the receiving groove 9 and the outer surface of the claw 5, and the tape 13 has not yet come into contact with the outer surface of the claw 5. When the bonding component is activated, the adjusting component is activated first. The motor 2 31 in the adjusting component drives the active bevel gear 32 to rotate. The active bevel gear 32 drives the bevel gear 29 to rotate through the bevel gear 30 and the rotating rod 28. The bevel gear 29 drives the cam 24 to rotate through the bevel gear 1 26 and the rotating shaft 23. The rotation of the cam 24 pushes the fixing frame 22 to move horizontally through the convex surface. The horizontal movement of the fixing frame 22 pushes the elastic extrusion head 21 to move linearly through the moving plate 20. The elastic extrusion head 21 pushes the adhesive surface of the tape 13 to contact the outer surface of the claw 5 through elastic deformation, thereby cleaning the outer surface of the claw 5. At the same time, the tape 13 that has been adhered will be wound up by the take-up roller 12.

[0047] After the gripper 5 is first adhered to by the adhesive component, the sweeping component can clean the gripper 5. Specifically, the motor 47 is started, driving the drive gear 45 to rotate. The drive gear 45 drives an external gear ring 44 and an intermediate gear 46 to rotate, and the intermediate gear 46 drives another external gear ring 44 to rotate. This causes the two external gear rings 44 to drive the movable cylinder 38 to rotate synchronously, with the two movable cylinders 38 rotating in opposite directions. This rotation of the movable cylinder 38 simultaneously drives several traveling bevel gears 41 to rotate. The traveling bevel gears 41 travel on the fixed bevel gear 43, causing the rotating shaft 39 to rotate on its own axis on the movable cylinder 38. This rotation of the movable cylinder 38 causes several elastic cleaning heads 40 to contact the outer surface of the gripper 5. The rotating elastic cleaning heads 40 remove the particles adhering to the gripper 5 through rotational friction. The multiple sets of elastic cleaning heads 40 on the two movable cylinders 38 are staggered, ensuring complete removal of particles.

[0048] After being cleaned by the sweeping component, the claw 5 will come into contact with the rear half of the bonding component, and then the second section will be bonded. After the second section of tape 13 is bonded, the dust removal action of the entire dust removal mechanism is completed.

[0049] By designing the negative pressure fan 48, ventilation duct, suction pipe three 36, suction pipe two 18 and suction pipe one 10, particles located inside the cleaning box 34, particles located in the groove 17 and particles located inside the receiving groove 9 can all be adsorbed to the outside of the shell 1, reducing the possibility of particles accumulating inside the shell 1.

[0050] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
