Detailed Implementation

[0023] The terms "front," "rear," "left," and "right" used in this application are in accordance with the appendix. Figure 1 The front, back, left, and right are shown.

[0024] This application provides an automatic circumferential welding machine cylinder loading and unloading production line, which facilitates the loading and unloading of gas cylinders and reduces the difficulty of operation for workers.

[0025] like Figure 1 As shown, the production line includes a first gas cylinder transport track 1, a first gas cylinder rolling platform 3, a motorized platform 4, a welding machine fixture 5, a second gas cylinder rolling platform 6, and a second gas cylinder transport track 7. The first gas cylinder transport track 1 and the second gas cylinder transport track 7 are parallel to each other and both extend in the front-back direction. The first gas cylinder rolling platform 3 is located to the left of the first gas cylinder transport track 1 and is adjacent to the first gas cylinder transport track 1. The second gas cylinder rolling platform 6 is located to the right of the second gas cylinder transport track 7 and is adjacent to the second gas cylinder transport track 7. The first gas cylinder rolling platform 3, the welding machine fixture 5, and the second gas cylinder rolling platform 6 are arranged in the left-right direction between the first gas cylinder transport track 1 and the second gas cylinder transport track 7.

[0026] The first gas cylinder transport track 1 includes a frame 11 and two rows of rollers 12 arranged sequentially in the front-back direction. Each roller 12 is rotatably mounted on the frame 11 around its axis. When the gas cylinder 9 to be welded is placed on the first gas cylinder transport track 1, the surface of each roller 12 is tangent to the surface of the gas cylinder 9, reducing the friction during the transport of the gas cylinder 9.

[0027] like Figure 1 , 2 As shown, a gas cylinder lifting device 2 is provided at the junction of the first gas cylinder transport track 1 and the first gas cylinder rolling platform 3. The gas cylinder lifting device 2 includes a lifting frame 21 that can move vertically and a lifting cylinder 22 that drives the lifting frame 21 to move vertically. When the gas cylinder 9 moves to the upper side of the lifting frame 21, the lifting cylinder 22 can push the lifting frame 21 to move upward, thereby lifting the gas cylinder 9 on the first gas cylinder transport track 1 and making the lower end of the gas cylinder 9 flush with the upper end surface of the first gas cylinder rolling platform 3. The upper end of the lifting frame 21 forms an inclined surface W that slopes towards the first gas cylinder rolling platform 3, providing conditions for the gas cylinder 9 to roll onto the first gas cylinder rolling platform 3, saving manpower and time in transferring the gas cylinder 9. When the gas cylinder 9 rotates to move onto the first gas cylinder rolling platform 3, the lifting cylinder 22 drives the lifting frame 21 to reset.

[0028] like Figure 1 , 3 As shown, the mobile platform 4 includes a platform support 41 and multiple casters 42 disposed at the bottom of the platform support 41. The platform support 41 is movably disposed between the first gas cylinder rolling platform 3 and the second gas cylinder rolling platform 6 via the casters 42, and the platform support 41 spans the welding machine fixture 5 in the left-right direction. When the mobile platform 4 moves, at least a portion of the platform support 41 is always within the working range of the welding machine fixture 5. The mobile platform 4 is configured to move freely between a first working position docked with the first gas cylinder transport track 1 and a second working position docked with the second gas cylinder rolling platform 6. When the mobile platform 4 is in the first working position, it provides support and a movement path for the gas cylinder 9 to be welded, which is transferred from the first gas cylinder rolling platform 3 to the welding machine fixture 5. When the mobile platform 4 is in the second working position, it provides support and a movement path for the welded gas cylinder 9, which is transferred from the welding machine fixture 5 to the second gas cylinder rolling platform 6. The mobile platform 4 facilitates the movement of gas cylinder 9 into and out of the welding machine fixture 5, reduces manual labor, and saves time and effort.

[0029] like Figure 1 , 3As shown in Figure 5, the welding machine fixture 5 includes a welding machine fixture base 52, a front gripping device 51 and a rear gripping device 54 arranged opposite each other, and a lifting platform 53 located between the front gripping device 51 and the rear gripping device 54. At least one of the front gripping device 51 and the rear gripping device 54 is configured to move left and right. When the gas cylinder 9 is located between the front gripping device 51 and the rear gripping device 54, at least one of the front gripping device 51 and the rear gripping device 54 moves in the front-back direction to clamp the gas cylinder 9 between the front gripping device 51 and the rear gripping device 54. Furthermore, when the gas cylinder 9 is clamped between the front gripping device 51 and the rear gripping device 54, the gas cylinder 9 can rotate about an axis extending in the front-back direction, which facilitates the worker to perform circumferential welding on the clamped gas cylinder 9. In the embodiment of this application, the rear gripping device 54 is configured to be movable in the front-back direction.

[0030] like Figure 3-5 As shown, the lifting platform 53 is a two-stage lifting platform capable of two-stage lifting. The lifting platform 53 includes a main lifting platform 533, a main hydraulic cylinder 531 that drives the main lifting platform 533 to move up and down, a pair of auxiliary lifting platforms 535 supported on the main lifting platform 533 and spaced apart in the front-rear direction, and a pair of auxiliary hydraulic cylinders 534 that drive the pair of auxiliary lifting platforms 535 to move up and down relative to the main lifting platform 533. Each auxiliary lifting platform 535 is equipped with at least two support rollers 538. When the gas cylinder 9 is supported on the lifting platform 53, each support roller 538 supports the circumference of the gas cylinder 9 and is tangential to the surface of the gas cylinder 9, allowing the gas cylinder 9 to rotate on the lifting platform 53, facilitating circumferential welding by workers. The main hydraulic cylinder 531 drives the main lifting platform 533 and the pair of auxiliary lifting platforms 535 on the main lifting platform 533 to move up and down in the vertical direction, achieving the first stage of lifting; the pair of auxiliary hydraulic cylinders 534 respectively drive the pair of auxiliary lifting platforms 535 to move up and down relative to the main lifting platform 533, achieving the second stage of lifting.

[0031] For gas cylinders 9 of different diameters, the lifting platform 53 can lift the gas cylinder 9 to a position where the front gripping device 51 and the rear gripping device 54 can clamp it; when the gas cylinder 9 is still below the clamping position after the first stage of lifting on the lifting platform 53, the auxiliary oil cylinder 534 drives the auxiliary lifting platform 535 to rise for the second stage of lifting, lifting the gas cylinder 9 to the clamping position.

[0032] The lifting platform 53 also includes a movable stage 537 that can move back and forth relative to the welding machine fixture base 52. The main lifting stage 533 is supported on the movable stage 537 and can support the gas cylinder 9 to move back and forth with the movable stage 537 relative to the welding machine fixture base 52, thereby adjusting the position of the gas cylinder 9 in the front-to-back direction. In this embodiment, slide rails 539 are respectively installed on both sides of the movable stage 537. The slide rails 539 are connected to the welding machine fixture base 52, and the movable stage 537 slides in cooperation with the slide rails 539. When the length of the gas cylinder 9 is different, the motorized platform 4, the lifting platform 53, and the rear gripping device 54 jointly adjust the position of the gas cylinder 9 so that the gas cylinder 9 can be clamped by the front gripping device 51 and the rear gripping device 54.

[0033] The bottom of the main lifting platform 533 is provided with a pair of front-to-back main limiting rods 532. Each main limiting rod 532 extends vertically and passes through the moving platform 537 from top to bottom, restricting the movement direction of the main lifting platform 533 when it is raised or lowered, thus preventing the main lifting platform 533 from shifting. The bottom of each auxiliary lifting platform 535 is provided with a pair of left-to-right auxiliary limiting rods 536. Each auxiliary limiting rod 536 extends vertically and passes through the main lifting platform 533 from top to bottom, restricting the movement direction of the corresponding auxiliary lifting platform 535 when it is raised or lowered, thus preventing the auxiliary lifting platform 535 from shifting.

[0034] Continue to refer to Figure 1 A baffle 71 is provided on the left side of the second gas cylinder transport track 7. The baffle 71 is used to block the welded gas cylinder 9 from rolling from the second gas cylinder rolling platform 6 on the right side of the second gas cylinder transport track 7 to the second gas cylinder transport track 7, so as to prevent the gas cylinder 9 from falling off the second gas cylinder transport track 7 due to inertia, and play a protective role for the gas cylinder 9.

[0035] The second gas cylinder transport track 7 includes a frame 72 and two rows of rollers 73 arranged sequentially in the front-to-back direction. The rollers 73 are rotatably mounted on the frame 72. The function of the rollers 73 is the same as that of the rollers 12 of the first gas cylinder transport track 1, and will not be described in detail here.

[0036] The workflow of this application is as follows: A worker pushes the motorized platform 4 to the first working position connected to the first gas cylinder rolling platform 3. The gas cylinder 9 to be welded is transported via the first gas cylinder transport track 1 to the top of the gas cylinder lifting device 2. The gas cylinder lifting device 2 lifts the gas cylinder 9 to be welded, causing it to roll onto the first gas cylinder rolling platform 3. The worker pushes the gas cylinder 9 to be welded along the first gas cylinder rolling platform 3 and the motorized platform 4. After the gas cylinder 9 to be welded rolls above the lifting platform 53, the movement of the gas cylinder 9 stops. The lifting platform 53 lifts the gas cylinder 9 to be welded and adjusts its position. The rear gripping device 54 moves closer to the front gripping device 51 to clamp the gas cylinder 9 to be welded; after the gas cylinder 9 is securely clamped, the worker performs circumferential welding; after welding is completed, the rear gripping device 54 moves away from the front gripping device 51 to release the welded gas cylinder 9, the worker pushes the motorized platform 4 to the second working position that is connected to the second gas cylinder rolling platform 6, the lifting platform 53 descends to place the welded gas cylinder 9 on the motorized platform 4, and the worker rolls the welded gas cylinder 9 via the motorized platform 4 and the second gas cylinder rolling platform 6 to the second gas cylinder transport track 7 to complete the entire operation process.
