Description

Technical Field

[0001] The present invention relates to the technical field of wall welding, in particular to modular assembled building wall welding equipment for house construction. Background Art

[0002] In the production process of modular prefabricated building walls, high-precision welding between wall panels is the key to ensuring structural strength and sealing;

[0003] The core structure and operating mode of traditional welding equipment are primarily designed for standard flat walls. Their rigid frames and fixed motion trajectories make it difficult to effectively fit or adapt to curved walls and curved components. Simple, universal fixtures are commonly used, with simplistic clamping surfaces and adjustment mechanisms. These fixtures lack dedicated adapters for special-shaped components and angle adjustment capabilities, typically providing only basic translation or simple rotation, and are unable to achieve multi-angle adjustment and posture locking. This makes it difficult to accurately achieve the required relative angle relationships for components during the clamping process. The welding path is highly dependent on the welder's manual operation skills and experience, requiring the welder to continuously manually control the movement of the welding torch along the preset weld seam while adjusting travel speed, torch angle, arc parameters, and other factors. This makes it difficult to maintain welding quality over time, resulting in poor welding quality stability. Due to the limited positioning capabilities of the fixture and the need for double-sided welding, the wall component often needs to be disassembled, repositioned, and clamped multiple times during the welding process. This repeated disassembly and assembly significantly prolongs the adjustment process, reducing production efficiency. While existing solutions to these issues may already exist, this application seeks to provide an alternative or replacement technical solution. Summary of the Invention

A moving block 11 is movably mounted on the upper end of the first screw rod 9, and the two sides of the lower end of the bottom semi-ring 12 are movably mounted on the upper ends of the two fixed guide rods 4. The two sides of the upper end of the top semi-ring 13 are movably mounted on the upper ends of the two movable guide rods 7, and the center of the upper end is connected to the lower end of the first moving block 11. The two ends of the limit assembly are respectively connected to the two sides of the bottom semi-ring 12 and the two sides of the top semi-ring 13.

At the same time, the four mounting sleeves 5 at the upper ends of the four vertical poles 2 follow the movement to ensure the lifting stability of the two mounting frames 6 until the limiting assembly between the top semi-ring 13 and the bottom semi-ring 12 is separated. Then, the first motor 10 is driven to work to independently drive the top semi-ring 13, and the top semi-ring 13 cooperates with the driving welding assembly to perform welding operations on large-scale walls.

[0036] In the specific implementation process, the limiting assembly includes: two limiting sleeves 16 and two limiting rods 17;

[0038] When the bottom semi-ring 12 moves with the top semi-ring 13, the two limiting rods 17 located on both sides of the top semi-ring 13 are respectively embedded in the two limiting sleeves 16. Under the fixed connection between the two limiting sleeves 16 and the bottom semi-ring 12, the purpose of connecting the bottom semi-ring 12 and the top semi-ring 13 can be achieved. When the lifting cylinder 8 is working, the two limiting rods 17 move upward with the top semi-ring 13 until they are separated from the two limiting sleeves 16, and the limiting effect of contacting the bottom semi-ring 12 and the top semi-ring 13 can independently adjust the position of the top semi-ring 13.

[0039] In a specific implementation process, the driving welding assembly includes: a second motor 18, a driving shaft 19, a driving gear 20, a multi-stage electric push rod 21 and a welding gun 22;

The multi-stage electric push rod 21 is fixedly mounted on the lower end of the mobile frame 15, and the welding gun 22 is fixedly mounted on the telescopic end of the multi-stage electric push rod 21.

[0041] When the top half ring 13 moves to the specified position, the second motor 18 located on one side of the movable frame 15 starts working, and the second motor 18 drives the driving shaft 19 and the driving gear 20 to rotate. Under the meshing action of the driving gear 20 and the arc-shaped rack 14, the movable frame 15 is driven to move around the top half ring 13 and the arc-shaped rack 14, changing the angle of the movable frame 15, and then driving the multi-stage electric push rod 21 to work, pushing the welding gun 22 to move toward the welding position until it fits with the welding position, and welding the joint position of the two modular prefabricated building walls.

[0043] Two mounting grooves 23 are arranged at the upper ends of the two fixing frames 3, four supporting blocks 24 are movably arranged at the two sides of the two mounting grooves 23, one end of each of the four mounting shafts 25 is movably arranged in the four supporting blocks 24 through bearings, two supporting rods 26 are connected to one end of the four mounting shafts 25, two second lead screws 27 are arranged at the bottom ends of the two supporting rods 26 through bearing plates, two third motors 28 are arranged at the lower ends of the two supporting rods 26, and the driving ends of the two third motors 28 are connected to one end of the two second lead screws 27, two fixed clamping plates 29 are arranged at the upper ends of the two supporting rods 26, two movable clamping frames 30 are arranged at the upper ends of the two supporting rods 26, and the bottom ends of the two movable clamping frames 30 are movably arranged at the upper ends of the two second lead screws 27, two center plates 31 are arranged at the centers of the side walls of the two fixing frames 3, four adjusting cylinders 32 are arranged at the two sides of the two center plates 31, and the telescopic ends of the four adjusting cylinders 32 are connected to the side walls of the four supporting blocks 24, the adjusting assembly is arranged at one side of one of the fixing frames 3, and the positioning assembly is arranged at one side of the other fixing frame 3.

[0044] When welding the modular assembly type building wall, the two modular assembly type building walls to be welded are placed on the upper ends of the two supporting rods 26 by the hoisting equipment, then the third motor 28 at the lower end of the supporting rod 26 is driven to work, the position of the two movable clamping frames 30 is changed through the cooperation of the third motor 28 and the second lead screw 27, until the two movable clamping frames 30 push the modular assembly type building walls to move close to the fixed clamping plates 29, and the modular assembly type building walls are clamped and fixed through the cooperation of the movable clamping frames 30 and the fixed clamping plates 29, then according to the requirement of the butt joint angle of the modular assembly type building wall, the four adjusting cylinders 32 at the two sides of the two center plates 31 are driven to move the four supporting blocks 24 in the two mounting grooves 23 through the four adjusting cylinders 32, the distance between the two supporting rods 26 is changed, the distance between the two modular assembly type building walls is adjusted, then the adjusting assembly and the positioning assembly are driven to change the angle of the two supporting rods 26 and the four mounting shafts 25 in the four supporting blocks 24, the deflection angle of the two modular assembly type building walls is adjusted, and finally the four adjusting cylinders 32 are driven again to butt joint the two modular assembly type building walls.

[0045] In the specific implementation process, the adjusting assembly comprises two worm gears 33, two guide strips 34, a lifting frame 35, a driving cylinder 36, a bidirectional worm 37, and a fourth motor 38.

[0047] When adjusting the distance between the two modular prefabricated building walls, the driving cylinder 36 at the upper end of the base plate 1 is contracted, driving the lifting frame 35 to move downward on one side of the two guide bars 34 until the bidirectional worm 37 is separated from the two worm wheels 33, and then the spacing of the four support blocks 24 is adjusted by adjusting the cylinder 32. After the adjustment is completed, the lifting frame 35 is pushed upward by the driving cylinder 36, so that the two ends of the bidirectional worm 37 engage with the bottom ends of the two worm wheels 33, and then the fourth motor 38 is driven to work.

When adjusting the angle of the two modular prefabricated building walls, the two positioning cylinders 40 retract, releasing the limit on the two positioning gears 41, and adjusting the angle of the two modular prefabricated building walls through the adjustment component. After the adjustment is completed, the two positioning cylinders 40 extend again and cooperate with the adjustment component to doubly fix the angle of the modular prefabricated building wall.
