Description

Technical Field

[0001] This invention relates to the field of metal assembly technology, specifically to an integrated machine for filling and assembling metal gas cylinders. Background Technology

[0002] A gas cylinder is a portable pressure vessel that can be refilled at normal ambient temperature, with a nominal working pressure greater than or equal to 0.2 MPa and a pressure-volume product greater than or equal to 1.0 MPa·L, containing gases, liquefied gases, and liquids with a standard boiling point equal to or lower than 60°C. Gas cylinders have a wide range of applications; they are indispensable in both production and daily life.

[0003] Gas cylinders are pressure vessels with explosion hazards. The media they contain are generally flammable, explosive, toxic, or highly corrosive. Their operating environment is more complex and harsher than that of other pressure vessels due to their mobility, repeated filling, the presence of unsettled operators, and changing environmental conditions. An explosion or leak in a gas cylinder often leads to fires, poisoning, or even catastrophic accidents, causing severe property damage, casualties, and environmental pollution. Traditionally, gas cylinders are assembled manually using welding. However, the large size and weight of metal gas cylinders make manual handling and turning difficult. Furthermore, aligning multiple sections of the cylinder manually during welding is challenging, affecting welding quality and efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated filling and assembly machine for metal gas cylinders, which solves the problems of low cylinder quality and efficiency caused by traditional manual welding and assembly of metal gas cylinders.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a metal gas cylinder filling and assembly integrated machine, comprising an adjustment device, a trimming device movably connected to the upper surface of the adjustment device, and assembly devices provided on both sides of the trimming device. The gas cylinder is clamped and fixed by the assembly devices. Under the action of the adjustment device, the assembly devices can move freely to adapt to the assembly of gas cylinders of different sizes, increasing the versatility of the equipment. After the two gas cylinder sections are aligned and assembled, the trimming device approaches the gas cylinder to maintain the external welded assembly. After the gas cylinder is fully inspected, it is filled with gas. The adjustment device includes a base plate, and the metal gas cylinder is assembled and filled on the top of the base plate. The two sections of the metal gas cylinder are respectively clamped on the top of the assembly device. By rotating the screw, the spacing of the guide rails is adjusted. When the spacing of the guide rails increases, the assembly device can move; conversely, when the spacing decreases, the assembly device is locked. A sliding groove is provided in the wall of the base plate, and screws are provided on both sides of the sliding groove. The outer surface of the screws is threaded with guide rails.

[0006] The assembly device includes a slider, with a support rod threadedly connected to the inner surface of the slider and an adjusting nut threadedly connected to the outer surface of the support rod. Slide rods are provided on both sides of the adjusting nut. When the assembly device is locked, the metal gas cylinders are aligned and welded, and assembly begins. After assembly, a trimming device slides along the slide groove, causing the welded metal gas cylinder to rotate. The trimming device removes excess protruding weld blocks from the outside of the gas cylinder by squeezing out the weld. Simultaneously, sealant or paint is applied to the weld joint for sealing and curing, preparing for subsequent inflation. A clamping device is fixedly connected to the top of the slide rod, and a rotating device is rotatably connected to the outer surface of the clamping device.

[0007] Preferably, the assembly device is slidably connected to the upper surface of the base plate via a slide groove. The slider slides along the upper surface of the base plate. Under the constraint of the guide rail, the assembly device can lock and move. For gas cylinders of different specifications, the height of the support rod can be controlled by rotating the adjusting nut. When the slide rod moves downward, the clamping device clamps the gas cylinder and moves downward, and vice versa. The outer surface of the screw is rotatably connected to the inner surface of the base plate, and the lower surface of the guide rail is slidably connected to the upper surface of the base plate.

[0008] Preferably, the outer surface of the slider is slidably connected to the outer surface of the guide rail, and the outer surface of the bottom end of the slide rod is slidably connected to the inner surface of the slider. Under the combined action of the slider and the adjusting nut, the gas cylinder can move freely up, down, left, and right. The equipment is highly flexible and can adapt to the assembly of gas cylinders of different specifications. The lower surface of the slider is slidably connected to the upper surface of the base plate.

[0009] Preferably, the clamping device includes a concave plate, a hydraulic cylinder is fixedly connected to the lower surface of the concave plate, a bent pipe is fixedly connected to the outer surface of the hydraulic cylinder, a push rod is slidably connected to the inner surface of the top end of the bent pipe, and a tension spring is provided on the outside of the push rod. The unassembled half of the gas cylinder is inserted downward from the top of the concave plate. Under the squeezing action of the gas cylinder, the guide plate is opened, the telescopic rod retracts, and as the gas cylinder continues to be squeezed in, the gas cylinder pushes the clamping plate open. The clamping plate slides along the inner surface of the concave plate, the tension spring retracts, the push rod is pressed into the inside of the bent pipe, and hydraulic oil is injected into the inside of the hydraulic cylinder. Under the reaction force of the hydraulic oil, the clamping plate clamps the metal gas cylinder. The clamping plate is fixedly connected to the outer surface of the tension spring, a guide plate is fixedly connected to the upper surface of the clamping plate, and a telescopic rod is fixedly connected to the outer surface of the guide plate.

[0010] Preferably, the lower surface of the concave plate is fixedly connected to the top of the support rod and the slide rod, the outer surface of the top of the bent tube is fixedly connected to the inner surface of the concave plate, and the left end of the tension spring is fixedly connected to the inner surface of the concave plate. Since the clamping device adopts a flexible connection, it can adapt to the clamping of gas cylinders of different diameters, and the equipment has greater adaptability and versatility. While ensuring that the gas cylinder can be clamped stably, the clamping device reduces the local pressure at the clamping point through the large contact area of ​​the clamping plate, preventing deformation. The right end of the push rod is fixedly connected to the outer surface of the clamping plate, the outer surface of the telescopic rod is fixedly connected to the outer surface of the clamping plate, and the lower surface of the clamping plate is slidably connected to the inner surface of the concave plate.

[0011] Preferably, the rotating device includes a turntable, a swing arm rotatably connected to the inner surface of the turntable, a pressure plate rotatably connected to the bottom end of the swing arm, the turntable being fixed to the outer surface of the concave plate, the pressure plate being located at the bottom of the concave plate during the alignment and approach of the gas cylinders, a drive shaft being fixedly connected to the outer surface of the left side of the pressure plate, and a suction cup being fixedly connected to the outer surface of the right side of the drive shaft.

[0012] Preferably, the outer surface of the turntable is fixedly connected to the outer surface of the concave plate, and the outer surface of the drive shaft is rotatably connected to the inner surface of the bottom end of the swing arm. After the two gas cylinders are aligned, the equipment begins to assemble and weld the gas cylinders. The swing arm rotates upward, the drive shaft pushes the pressure plate close to the gas cylinder, the suction cup holds the two ends of the gas cylinder, and then the drive shaft rotates. The transmission force on the gas cylinder is greater than the clamping resistance of the clamping device, and the gas cylinder rotates, which facilitates subsequent inspection and cleaning and maintenance of the welded assembly. The outer surface of the left side of the pressure plate is in contact with the outer surface of the swing arm.

[0013] Preferably, the trimming device includes an adjusting block, an inclined rod rotatably connected to the upper surface of the adjusting block, a connecting block rotatably connected to the top of the inclined rod, the adjusting block sliding along the slide groove, and then rotating the inclined rod to adjust the connecting block so that the clamping plate can wrap around the outer surface of the gas cylinder. As the rotating device rotates, the roller continuously rolls and removes the excess warped edge at the weld of the gas cylinder. A connecting pipe is fixedly connected to the inner surface of the connecting block, a clamping plate is fixedly connected to the outer surface of the bottom end of the connecting pipe, and a roller is rotatably connected to the inner surface of the clamping plate.

[0014] Preferably, the lower surface of the adjusting block is slidably connected to the inner surface of the base plate via a sliding groove. During this process, the connecting pipe sprays oil or paint onto the welding joint of the gas cylinder to prevent rust and facilitates inspection for leaks at the welding joint. Because the trimming device has a flexible structure, it can adapt to the assembly of gas cylinders of different sizes. The outer surface of the connecting block is fixedly connected to the outer surface of the clamping plate.

[0015] This invention provides an integrated machine for filling and assembling metal gas cylinders. It has the following advantages:

[0016] (I) The metal gas cylinder filling and assembly integrated machine, through the setting of an adjustment device, allows the metal gas cylinder to be assembled and inflated on the top of the base plate when the equipment is in use. The two ends of the metal gas cylinder are respectively clamped on the top of the assembly device. By rotating the screw, the spacing of the guide rails is adjusted. When the spacing of the guide rails increases, the assembly device can move. Conversely, when the spacing of the guide rails decreases, the assembly device is locked. When the assembly device is locked, the metal gas cylinder is aligned and welded, and the assembly begins. After the assembly is completed, the trimming device slides along the slide groove. The welded metal gas cylinder rotates, and the trimming device squeezes and removes the excess protruding weld blocks on the outside of the gas cylinder. At the same time, the weld is sealed with glue or oil and paint for sealing and curing, preparing for subsequent inflation. This solves the problem of low efficiency in the traditional manual assembly of gas cylinders.

[0017] (II) The metal gas cylinder filling and assembly integrated machine, by setting up an assembly device, when the equipment is in use, the slider slides along the upper surface of the base plate. Under the restriction of the guide rail, the assembly device can lock and move. For gas cylinders of different specifications, the height of the support rod can be controlled by rotating the adjusting nut. When the slider moves downward, the clamping device clamps the gas cylinder and moves downward, and vice versa. Under the combined action of the slider and the adjusting nut, the gas cylinder can move freely up, down, left and right. The equipment has high flexibility and can adapt to the assembly of gas cylinders of different specifications, solving the problem of fixed structure of traditional gas cylinder assembly equipment.

[0018] (III) The metal gas cylinder filling and assembly integrated machine is equipped with a clamping device. When the equipment is in use, the unassembled half of the gas cylinder is inserted downwards from the top of the concave plate. Under the squeezing action of the gas cylinder, the guide plate is opened and the telescopic rod retracts. As the gas cylinder continues to be squeezed in, the gas cylinder pushes the clamping plate open. The clamping plate slides along the inner surface of the concave plate, the tension spring retracts, the push rod is pressed into the inside of the bend, and hydraulic oil is injected into the inside of the oil cylinder. Under the reaction force of the hydraulic oil, the clamping plate clamps the metal gas cylinder. Since the clamping device adopts a flexible connection, it can adapt to the clamping of gas cylinders of different diameters. The equipment has a large adaptability and versatility. While ensuring that the gas cylinder can be clamped stably, the clamping device reduces the local pressure at the clamping point through the large contact area of ​​the clamping plate, preventing deformation. This solves the problem that traditional mechanical claws clamping gas cylinders have poor equipment flexibility and are prone to damaging the outer surface of the gas cylinder.

[0019] (iv) The metal gas cylinder filling and assembly integrated machine is equipped with a rotating device. When the equipment is in use, the turntable is fixed on the outer surface of the concave plate. During the process of aligning and approaching the gas cylinder, the pressure plate is located at the bottom of the concave plate. After the two gas cylinders are aligned, the equipment begins to assemble and weld the gas cylinder. The swing arm rotates upward, the transmission shaft pushes the pressure plate close to the gas cylinder, and the suction cup holds the two ends of the gas cylinder. Then the transmission shaft rotates. The transmission force on the gas cylinder is greater than the clamping resistance of the clamping device, and the gas cylinder rotates. This facilitates subsequent inspection and cleaning and maintenance of the welding assembly area, and solves the problems of traditional gas cylinders being heavy and bulky, and low efficiency of manual turning.

[0020] (V) The metal gas cylinder filling and assembly integrated machine is equipped with a trimming device. When the equipment is in use, the adjusting block slides along the slide groove, and then the inclined rod is rotated to adjust the connecting block so that the clamping plate can wrap around the outer surface of the gas cylinder. As the rotating device rotates, the rollers continuously roll and press, and the excess warp edges at the gas cylinder welding point are rolled and removed. During this process, the connecting pipe sprays oil or paint onto the gas cylinder welding point to prevent rust and facilitates the inspection of whether there is a leak at the welding point. Because the trimming device has a flexible structure, it can adapt to the assembly of gas cylinders of different sizes, solving the problem that traditional gas cylinders need to be manually turned over for inspection and maintenance after assembly and welding.

[0021] (vi) The integrated filling and assembly machine for the metal gas cylinder is equipped with an adjustment device, a trimming device, and an assembly device. When the equipment is in use, the gas cylinder is clamped and fixed by the assembly device. Under the action of the adjustment device, the assembly device can move freely to adapt to the assembly of gas cylinders of different sizes, thereby increasing the versatility of the equipment. After the two gas cylinder sections are aligned and assembled, the trimming device approaches the gas cylinder to maintain the external welding assembly. After the gas cylinder is completely inspected, it is filled with gas, which solves the problem of large errors in manual assembly. Attached Figure Description

[0031] Example 1:

[0032] Please see Figures 1-7 The present invention provides a technical solution: a metal gas cylinder filling and assembly integrated machine, including an adjustment device 1, a trimming device 2 movably connected to the upper surface of the adjustment device 1, assembly devices 3 arranged on both sides of the trimming device 2, the adjustment device 1 including a base plate 4, a sliding groove 5 opened in the wall of the base plate 4, screws 6 arranged on both sides of the sliding groove 5, and a guide rail 7 threadedly connected to the outer surface of the screws 6.

[0034] Assembly device 3 is slidably connected to the upper surface of base plate 4 via slide groove 5, the outer surface of screw 6 is rotatably connected to the inner surface of base plate 4, the lower surface of guide rail 7 is slidably connected to the upper surface of base plate 4, the outer surface of slider 10 is slidably connected to the outer surface of guide rail 7, the outer surface of the bottom end of slide rod 13 is slidably connected to the inner surface of slider 10, and the lower surface of slider 10 is slidably connected to the upper surface of base plate 4.

[0035] In use, the metal gas cylinder is assembled and inflated on the top of the base plate 4. The two ends of the metal gas cylinder are clamped on the top of the assembly device 3. By rotating the screw 6, the spacing of the guide rails 7 is adjusted. When the spacing of the guide rails 7 increases, the assembly device 3 can move. Conversely, when the spacing of the assembly device 3 decreases, the assembly device 3 is locked. When the assembly device 3 is locked, the metal gas cylinder is aligned and welded, and the assembly begins. After the assembly is completed, the trimming device 2 slides along the slide groove 5. The welded metal gas cylinder rotates, and the trimming device 2 squeezes out the excess protruding weld blocks on the outside of the gas cylinder. At the same time, the weld is sealed with glue or oil and paint for sealing and curing, in preparation for subsequent inflation.

[0036] The slider 10 slides along the upper surface of the base plate 4. Under the constraint of the guide rail 7, the assembly device 3 locks and moves. For gas cylinders of different specifications, the height of the support rod 11 can be controlled by rotating the adjusting nut 12. The slide rod 13 moves downward and the clamping device 14 clamps the gas cylinder and moves downward. Conversely, they move upward together. Under the combined action of the slider 10 and the adjusting nut 12, the gas cylinder can move freely up, down, left, and right. The equipment is highly flexible and can adapt to the assembly of gas cylinders of different specifications.

[0037] Example 2:

[0040] The trimming device 2 includes an adjusting block 40, an inclined rod 41 rotatably connected to the upper surface of the adjusting block 40, a connecting block 42 rotatably connected to the top of the inclined rod 41, a connecting pipe 43 fixedly connected to the inner surface of the connecting block 42, a clamping plate 44 fixedly connected to the outer surface of the bottom end of the connecting pipe 43, a roller 45 rotatably connected to the inner surface of the clamping plate 44, the lower surface of the adjusting block 40 slidingly connected to the inner surface of the base plate 4 through a sliding groove 5, and the outer surface of the connecting block 42 fixedly connected to the outer surface of the clamping plate 44.

[0041] In use, the unassembled half of the gas cylinder is inserted downwards from the top of the concave plate 20. Under the squeezing action of the gas cylinder, the guide plate 26 is opened, and the telescopic rod 27 retracts. As the gas cylinder continues to be squeezed in, it pushes the clamping plate 25 open. The clamping plate 25 slides along the inner surface of the concave plate 20, the tension spring 24 retracts, and the push rod 23 is pressed into the inside of the bend 22. Hydraulic oil is injected into the inside of the oil cylinder 21. Under the reaction force of the hydraulic oil, the clamping plate 25 clamps the metal gas cylinder. Since the clamping device 14 adopts a flexible connection, it can adapt to the clamping of gas cylinders of different diameters. The equipment has a large adaptability and versatility. While ensuring that the gas cylinder can be clamped stably, the clamping device 14 reduces the local pressure at the clamping point through the large contact area of ​​the clamping plate 25, preventing deformation.

[0042] The turntable 30 is fixed on the outer surface of the concave plate 20. During the process of aligning and approaching the gas cylinders, the pressure plate 32 is located at the bottom of the concave plate 20. After the two gas cylinders are aligned, the equipment begins to assemble and weld the gas cylinders. The swing arm 31 rotates upward, and the transmission shaft 33 pushes the pressure plate 32 closer to the gas cylinder. The suction cup 34 sucks up both ends of the gas cylinder. Then the transmission shaft 33 rotates. The transmission force on the gas cylinder is greater than the clamping resistance of the clamping device 14. The gas cylinder rotates, which facilitates subsequent inspection and cleaning and maintenance of the welding assembly.

[0043] The adjusting block 40 slides along the slide groove 5, and then the inclined rod 41 is rotated to adjust the connecting block 42 so that the clamping plate 44 can cover the outer surface of the gas cylinder. As the rotating device 15 rotates, the roller 45 continuously rolls and removes the excess warp edge at the gas cylinder welding point. During this process, the connecting pipe 43 sprays oil or paint onto the gas cylinder welding point to prevent rust and facilitates the inspection of whether there is any leakage at the welding point. Because the trimming device 2 has a flexible structure, it can adapt to the assembly of gas cylinders of different sizes.

[0044] The gas cylinder is clamped and fixed by the assembly device 3. Under the action of the adjustment device 1, the assembly device 3 can move freely to adapt to the assembly of gas cylinders of different sizes, increasing the versatility of the equipment. After the two gas cylinders are aligned and assembled, the trimming device 2 approaches the gas cylinder to maintain the external welding assembly. After the gas cylinder is fully inspected, gas is filled into the gas cylinder.
