Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and particularly to a cantilever welding machine device for compensator processing. Background Art

[0002] Compensators are also commonly called expansion joints or telescopic joints. They are composed of a bellows (an elastic element) that forms the main body of their work, and accessories such as end pipes, brackets, flanges, and conduits. They belong to a type of compensating element. By utilizing the effective telescopic deformation of the bellows of their main body, they can absorb dimensional changes in pipelines, conduits, containers, etc. caused by reasons such as thermal expansion and contraction, or compensate for axial, lateral, and angular displacements of pipelines, conduits, containers, etc. They can also be used for noise reduction and vibration damping, and are widely used in modern industry.

[0003] During the processing of compensators, an arc welding operation needs to be carried out on them using a cantilever welding machine device. The existing cantilever welding machine device for compensator processing has a relatively simple structure. During use, it is fixed by a chuck and drives the compensator to rotate to achieve continuous welding operation. However, during the clamping process of the compensator, it is necessary for workers to support it. The compensator is relatively heavy, making it inconvenient for workers to operate and prone to injury. Moreover, when the compensator needs to be turned for welding again during welding, it is also necessary for workers to turn it and perform a clamping operation again, which is rather troublesome.

[0057] As Figure 10 shown, an assembly hole 51 is formed on the upward movement bearing platform 5, and a bearing guiding hole 52 is also formed on the upward movement bearing platform 5.

A push block 571 is provided at the lower end of the push plate frame 57. A first runner 572 is installed on the push block 571.

[0059] As Figure 4 and Figure 9 shown, the compensator steering mechanism includes a rotating bearing column 3 and a fixed carrier plate 6. A first bearing 31 is sleeved on the rotating bearing column 3. The first bearing 31 is installed in the installation channel 20. A connecting moving cavity 32 is provided in the rotating bearing column 3. A rotating linkage groove 33 is provided in the connecting moving cavity 32. A connecting rotating column 54 is inserted into the connecting moving cavity 32. A rotating connecting bar 55 is inserted into the rotating linkage groove 33. A rotating gear 34 is fixedly provided at the lower end of the rotating bearing column 3. Gear fixing holes 35 are symmetrically provided on the rotating gear 34.

[0060] As Figure 3 and Figure 4 shown, a fixed mating column 61 is provided on the fixed carrier plate 6. The upper end of the fixed mating column 61 is inserted into the mating jack 27. A movable connecting rod 62 is hinged on the fixed carrier plate 6. The lower end of the movable connecting rod 62 is hinged to a driving carrier plate 63. A mating carrier plate 64 is fixedly provided on the driving carrier plate 63. A second runner 65 is installed on the mating carrier plate 64. A mating bearing hole 66 is provided on the fixed carrier plate 6. A guiding bearing rod 26 is inserted into the mating bearing hole 66. A connecting spring 67 is sleeved on the guiding bearing rod 26. The two ends of the connecting spring 67 are respectively fixed on the installation carrier plate 25 and the driving carrier plate 63. In addition, when the fixed mating column 61 fixes the rotating gear 34, its lower end is inserted into the gear fixing hole 35.

[0061] As Figure 6 and Figure 12 shown, the steering drive assembly includes a limiting vertical rod 17 and a driving carrier plate 7. The limiting vertical rod 17 is fixedly provided on one side of the welding machine table 1. The driving carrier plate 7 is sleeved on the limiting vertical rod 17. A limiting through hole 71 is provided on the driving carrier plate 7. The limiting vertical rod 17 is inserted into the limiting through hole 71. A supporting carrier column 72 is fixedly provided on the driving carrier plate 7. A rack 73 is fixedly provided at the lower end of the supporting carrier column 72. An inclined surface mating strip 74 is also fixedly provided on the driving carrier plate 7. The surface of the inclined surface mating strip 74 is smooth and free of burrs.

[0062] When welding the compensator, place it on the support arc plate 56, then rotate the rotating screw 562. Under the action of the thread, the movable strip 58 moves downward, which can drive the pressing ring 59 to move downward, so that the pressing ring 59 presses on the compensator to play a role of pressing and limiting, ensuring the stability of the compensator during movement. After placing the compensator, start the hydraulic rod 13 to drive the moving platform 2 to move in the direction of the three-jaw chuck 11. As the moving platform 2 moves, under the action of the pulling frame 16, the upward pushing drive plate 4 will be driven to move in the direction of the moving platform 2 until the mating connecting column 42 is inserted into the holding frame 15. As the upward pushing drive plate 4 moves, under the action of the upward pushing connecting rod 43, the upward moving bearing platform 5 will be driven to move upward, and then the compensator can be driven to move to the working height. And as the upward moving bearing platform 5 moves upward, under the action of the first runner 572, the driving bearing plate 7 will be pushed upward. In this way, when the moving platform 2 moves in the direction of the three-jaw chuck 11, the rotating gear 34 will not mesh with the rack 73, and at the same time, the second runner 65 will not contact the inclined surface mating strip 74. When the compensator moves to the three-jaw chuck 11, at this time, the first runner 572 is separated from the driving bearing plate 7, and the driving bearing plate 7 moves downward and resets under its own gravity. Start the three-jaw chuck 11 to clamp it, and then rotate the rotating screw 562 in the reverse direction to make the movable strip 58 move upward, that is, the pressing ring 59 no longer presses on the compensator to release the compensator. Then start the hydraulic rod 13 to drive the moving platform 2 to move in the reverse direction to separate from the compensator. When the compensator needs to be turned and welded again, the hydraulic rod 13 drives the moving platform 2 to move in the direction of the three-jaw chuck 11 again, so that the support arc plate 56 supports the compensator. Then the three-jaw chuck 11 releases the compensator, and the compensator is pressed and limited by the pressing ring 59, driving the compensator to move in the reverse direction. When moving, the second runner 65 will contact the inclined surface mating strip 74. In this way, under the action of the inclined surface mating strip 74, the driving carrier plate 63 will be pushed to move. As the driving carrier plate 63 moves, under the action of the movable connecting rod 62, the fixed carrier plate 6 will be driven to move upward, so that the fixed mating column 61 exits the gear fixing hole 35. At the same time when exiting, the rotating gear 34 also meshes with the rack 73. In this way, under the action of the rack 73, the rotating gear 34 will be driven to rotate. As the rotating gear 34 rotates, the support arc plate 56 can be rotated 180 degrees, and thus the turning around of the compensator can be realized. When the rotating gear 34 is separated from the rack 73, the second runner 65 is also separated from the inclined surface mating strip 74. In this way, under the action of the connecting spring 67 and the self-gravity of the fixed carrier plate 6, the fixed mating column 61 moves downward again and is inserted into the gear fixing hole 35 to realize the fixing of the rotating gear 34, and then the fixing of the support arc plate 56 can be realized. After the turning is completed, the hydraulic rod 13 drives it to move in the direction of the three-jaw chuck 11 again, and it can be clamped and fixed again by the three-jaw chuck 11 for welding operation.The whole process requires little manual operation. All that the staff need to do is to place the compensator on the supporting arc plate 56 and rotate the rotating screw 562, which is very convenient.
