Description

An automatic welding device for circumferential seams of pressure vessels with adaptive adjustment function Technical Field

[0001] This utility model relates to the field of pressure vessel circumferential weld technology, and in particular to an automatic pressure vessel circumferential weld device with adaptive adjustment function. Background Technology

[0002] In the field of pressure vessel manufacturing, circumferential welding is a key process to ensure the structural strength and sealing performance of the vessel. With the diversification of industrial requirements for pressure vessel specifications, the size range, weight distribution, and shape differences of medium and large-sized pressure vessels have increased significantly. Traditional circumferential welding equipment faces multiple technical bottlenecks when dealing with such complex working conditions.

[0003] A welding device for welding circumferential seams of pressure vessels, with publication number CN217193402U, includes a support beam. A fixed plate is fixedly installed on the upper surface of the support beam. A drive shaft is rotatably connected inside the fixed plate. An active turntable is fixedly installed on the end face of the drive shaft. A connecting belt is provided on the outer surface of the drive shaft. A drive motor is fixedly installed on the upper surface of the fixed plate. This welding device for welding circumferential seams of pressure vessels improves the concentricity between pressure vessels by setting up structures such as a movable plate, threaded rod, auxiliary block, and threaded hole. When the threaded rod rotates, the movable plate can horizontally connect the pressure vessel with another pressure vessel by utilizing the threaded connection relationship between the threaded hole and the threaded rod. However, because it cannot adaptively adjust according to the weight of pressure vessels of different diameters or weights, it leads to extended production preparation time and reduced equipment utilization.

[0004] Therefore, it is necessary to design an automatic pressure vessel circumferential welder with adaptive adjustment function that can adaptively adjust and quickly clamp according to the weight of pressure vessels of different medium and large sizes, is simple to operate, flexible and convenient to use, and improves work efficiency.

[0005] To overcome the shortcomings of existing automatic pressure vessel circumferential welding devices, which cannot adaptively adjust to the weight of pressure vessels of different diameters or weights, resulting in extended production preparation time and reduced equipment utilization, this utility model provides an automatic pressure vessel circumferential welding device with adaptive adjustment function that can adaptively adjust and quickly clamp pressure vessels of different medium and large sizes, is simple to operate, flexible and convenient to use, and improves work efficiency.

[0006] An automatic welding device for circumferential seams of pressure vessels with adaptive adjustment function includes a welding table, fixed columns, adjusting rods, limiting plates, fixing knobs, pins, an adjustable welding torch, an adjusting component, and a rotating component. Two fixed columns are connected to the upper front side of the welding table, and two more are slidably connected to the rear side of the welding table. Adjusting rods are connected to the outer sides of the middle of each fixed column. Limiting plates are slidably connected between adjacent left and right adjusting rods. Fixing knobs are threaded onto both sides of the limiting plates. Pins are engaged between the two rear left and right fixed columns and the welding table. A robotic arm is located in the middle right side of the welding table, and an adjustable welding torch is connected to the robotic arm. The fixed columns are equipped with an adjusting component capable of adaptively adjusting and quickly clamping pressure vessels of different medium and large sizes according to their weight. The adjusting component is equipped with a rotating component capable of automatically rotating the pressure vessel.

The upper part of each fixed post is slidably connected to a first stop, and each first stop is connected to an adjacent fixed post by a first spring. The lower part of each fixed post is slidably connected to a second stop, and each second stop contacts an adjacent first stop. Each second stop is connected to an adjacent fixed post by a second spring. A limiting rod is connected to the lower side of each first stop, and the limiting rod contacts an adjacent second stop. The portions of the second stops that are far apart from each other are threadedly connected to a locking nut, and the locking nut contacts an adjacent fixed post.

[0010] Optionally, the portion of the first stop and the second stop that is close to each other is a wedge-shaped structure.

[0011] Optionally, it also includes a rotating assembly, which includes side rollers, rollers, connecting plates, and motors. Multiple side rollers are rotatably connected to the limit rods. The parts of the first stops that are close to each other are also rotatably connected to two upper and lower side rollers.

The front of the first and third connecting plates from front to back are connected to two motors, and rollers are connected to the output shafts of the motors. The rollers are rotatably connected to the adjacent connecting plates.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model uses the gravity of the pressure vessel to drive the second stop to move downward, and the downward movement of the second stop to squeeze the first stop, causing the first stop to move inward. This achieves the effect of adaptive adjustment and quick clamping according to the weight of pressure vessels of different medium and large sizes. It is simple to operate, flexible and convenient to use, and improves work efficiency.

[0013] 2. This utility model achieves the effect of limiting pressure vessels of different lengths and preventing displacement of the pressure vessel by rotating and tightening the locking nut, then rotating and loosening the fixing knob, and then moving and adjusting the limiting plate on the adjusting rod so that the limiting plate contacts the pressure vessel.

[0020] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0021] An automatic welding device for circumferential seams of pressure vessels with adaptive adjustment function, as shown in Figures 1, 4, and 5, includes a welding table 1, fixed columns 2, adjusting rods 3, limiting plates 4, fixing knobs 5, pins 8, an adjustable welding torch 16, an adjustment assembly, and a rotating assembly. Two fixed columns 2 are connected to the upper front of the welding table 1, and two more fixed columns 2 are slidably connected to the rear of the welding table 1. Adjusting rods 3 are connected to the outer sides of the middle of each fixed column 2. Limiting plates 4 are slidably connected between adjacent left and right adjusting rods 3. Fixing knobs 5 are threadedly connected to both sides of the limiting plates 4. The fixing knobs 5 have anti-slip textures for easy gripping. Pins 8 are engaged between the two rear left and right fixed columns 2 and the welding table 1. Grip blocks are provided on the upper parts of the pins 8 for easy gripping. A robotic arm is located in the middle right of the welding table 1, and an adjustable welding torch 16 is connected to the robotic arm. An adjustment assembly is located on the fixed columns 2, and a rotating assembly is located on the adjustment assembly.

[0022] As shown in Figures 1-3, the adjustment assembly includes a first stop 6, a first spring 7, a second stop 9, a second spring 10, a limiting rod 15, and a locking nut 17. The upper part of each fixed post 2 is slidably connected to the first stop 6, and the first stop 6 is connected to the adjacent fixed post 2 by the first spring 7. The lower part of each fixed post 2 is slidably connected to the second stop 9, and the second stop 9 is in contact with the adjacent first stop 6. The parts of the first stop 6 and the second stop 9 that are close to each other are wedge-shaped structures. The second stop 9 is connected to the adjacent fixed post 2 by the second spring 10. The lower side of each first stop 6 is connected to the limiting rod 15, and the limiting rod 15 is in contact with the adjacent second stop 9. The parts of the second stop 9 that are far apart from each other are threadedly connected to the locking nut 17, and the locking nut 17 is in contact with the adjacent fixed post 2.
