Description

Technical Field

[0001] This invention relates to the field of tent frame manufacturing technology, and in particular to a welding machine for outdoor tent frame manufacturing. Background Technology

[0002] Outdoor tents are core equipment for outdoor activities such as hiking, mountaineering, and camping. Their frames are key components determining the tent's structural stability, load-bearing capacity, and lifespan. They are mostly made of lightweight metal materials such as aluminum alloy and thin-walled steel pipes, welded together using straight pipes, bent pipes, and T-joints, balancing lightweight design with high strength. With the large-scale development of the outdoor equipment market, tent frame production is gradually shifting from manual to automated methods. Early tent frame welding primarily used manual arc welding and simple gas shielded welding, combined with manual clamping and positioning. However, as competition intensifies in the outdoor equipment industry, market demands for tent frame quality, cost, and delivery time are constantly increasing. Welding technology urgently needs to be upgraded towards automation, intelligence, high precision, and high adaptability.

[0003] Existing rod welding equipment cannot handle the fumes generated during welding, and cannot clamp and fix rods of different diameters. When the welded rods rotate, it is difficult to ensure the consistency of the weld. Summary of the Invention

[0027] The clamping device 49 includes a support column 491 and a movable plate 492. A rotating sleeve 493 is rotatably connected to the outside of the support column 491 via a bearing. A clamping plate 494 is fixedly connected to the outside of the rotating sleeve 493. A limiting plate 495 is fixedly connected to the outside of the support column 491. An arc spring 496 is fixedly connected to the outside of the limiting plate 495.

[0029] In operation, the worker places two sets of rod-shaped workpieces to be welded onto two sets of arc-shaped clamping plates 48 in sequence, and presses the two sets of ends to be welded together. Then, the electric telescopic rod 417 is activated, which drives the second piston rod 416 to squeeze into the second sleeve 415, gradually squeezing the hydraulic oil in the second sleeve 415 into the hydraulic tank 414. The hydraulic pressure in the hydraulic tank 414 increases and flows into the first sleeve 413. The hydraulic oil squeezed into the first sleeve 413 compresses and pushes the first piston rod 412, which drives the lower pressure plate 411 to slide down. The lower pressure plate 411 clamps the rods on the arc-shaped clamping plates 48, fixing the rods between the lower pressure plate 411 and the arc-shaped clamping plates 48. Then, the electric slide rail 2 is activated, and the electric slider inside the electric slide rail 2 drives the fixed plate 7 to move. The fixed plate 7, through the positioning plate 6, can move the welding assembly 8 to the designated position, and then the welding assembly... Part 8 can be used to weld the end faces of two sets of rods. During the welding process, the suction pump 93 is turned on. The suction pump 93 draws the fumes generated during welding into the gas delivery pipe 94 through the suction pipe 95. The fumes entering the gas delivery pipe 94 enter the purification cylinder 91 through the exhaust pipe 96 and the exhaust pipe 97. After being filtered by the filter components in the purification cylinder 91, they are discharged through the connecting pipe 92. This can absorb the fumes generated during welding in a timely manner and avoid pollution of the processing environment. When welding the rods, the drive motor 45 is turned on. The drive motor 45 drives the rotating shaft 44 to rotate. The rotating shaft 44 drives the reinforcing plate 41 and the arc-shaped fixing plate 42 to rotate through the belt transmission mechanism 43. This can drive the rods between the reinforcing plate 41 and the arc-shaped fixing plate 42 to rotate. This can clamp and fix rods of different diameters to prevent the rods from shaking during processing. It can also drive the two sets of welding rods to rotate synchronously to ensure the consistency of the weld.

[0030] When the first piston rod 412 drives the lower pressure plate 411 to slide down, the lower pressure plate 411 drives the support column 491 and the rotating sleeve 493 to move through the bracket. During the movement, the rotating sleeve 493 uses the arc spring 496 to lock the clamping plate 494 into the clamping tooth 497. Due to the obstruction of the clamping tooth 497, the clamping plate 494 cannot move upward, thus locking the position of the lower pressure plate 411, further stabilizing the clamping of the rod and ensuring the stability of the rod during rotation. When the rod is removed, the electronic push rod 498 is activated to pull the moving plate 492 to move. The moving plate 492 drives the clamping tooth 497 to disengage from the clamping plate 494, and the arc spring 496 pulls the clamping plate 494 back through the rebound force.

[0031] Second embodiment, please refer to Figures 1-11 The present invention provides a technical solution: Based on the first embodiment, the support device 5 includes an electronic lifting rod 51, a connecting plate 52 is fixedly connected to the top of the electronic lifting rod 51, a V-shaped plate 53 is fixedly connected to the top of the connecting plate 52, an installation port 54 is provided on the V-shaped plate 53, and a support roller 55 is rotatably connected to the inner wall of the installation port 54 through a rotating bracket.

[0032] The bottom of the electronic lifting rod 51 is fixedly connected to the top of the base plate 3. Multiple sets of support rollers 55 are provided, and the multiple sets of support rollers 55 are evenly distributed in the mounting port 54.

[0033] In use, when processing long rods, the electronic lifting rod 51 is activated, which pushes the connecting plate 52 upward. The connecting plate 52 drives the V-shaped plate 53 to move, and the V-shaped plate 53 drives the support roller 55 to move to the outside of the bottom of the rod, thus supporting the cantilever end of the rod and preventing the cantilever end from drooping when processing long rods, improving the stability of processing long rods. In addition, it can be linked with the clamping device 4 to adapt to rods of different diameters.

[0034] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
