Technical Field
[0001] This utility model belongs to the field of welding equipment technology, specifically relating to a multi-dimensional adjustable combined welding device. Background Technology
[0002] In the field of modern industrial manufacturing, welding and cutting are key processing technologies and are widely used in many industries such as automobile manufacturing, shipbuilding, aerospace, and building steel structures. With the continuous development of technology, welding and cutting technology is also constantly being innovated. Automation and intelligence have become important trends in industry development in order to improve production efficiency, ensure welding quality, reduce labor intensity, and reduce the impact of human factors on production.
[0003] Currently, the most common welding and cutting equipment on the market includes articulated robots, welding carriages, and clamp-type welding molds, but these devices all have certain limitations in practical applications:
[0004] While articulated robots possess high flexibility and automation, playing a crucial role in automated production lines for large workpieces, they also have significant drawbacks. Firstly, their substantial weight necessitates specialized mounting foundations and fixing devices, increasing installation costs and floor space requirements. This also limits their mobility and rapid deployment across different work environments. In construction sites or small workshops, their large size and weight make them unsuitable due to limited space. Secondly, articulated robots are relatively expensive, making their purchase cost too high for many small and medium-sized enterprises, thus restricting their widespread application.
[0005] Welding carriages are a common type of automated welding equipment. They can move on a preset track to complete welding tasks in straight lines or simple curves. However, the application range of welding carriages is relatively narrow. For welding work on small-diameter pipes, due to the limitations of the structure and movement mode of the welding carriage, it is difficult to achieve precise welding operations and meet the quality requirements of small pipe welding. In addition, welding carriages have poor adaptability and flexibility when dealing with workpieces with complex shapes, requiring additional auxiliary devices and complex programming settings, which increases the difficulty and cost of operation.
[0006] Clamp-type welding molds are specialized welding tools designed for workpieces of specific specifications. The mold is fixed to the workpiece by clamps, guiding the welding torch for welding. The advantage of this type of mold is that it is relatively simple to operate. However, for workpieces of different specifications and shapes, multiple different clamp-type welding molds are required. This not only increases the manufacturing cost of the mold and the difficulty of inventory management, but also makes the mold replacement and debugging process more cumbersome, affecting production efficiency. At the same time, clamp-type welding molds have poor versatility and are difficult to adapt to diverse welding needs.
[0007] In addition, most existing welding and cutting equipment is made of heavy materials, resulting in a large overall weight of the equipment, which makes it inconvenient to move and transport. In some working environments with limited operating space, such as narrow corners of construction sites or the internal structure of high-rise buildings, the bulky nature of traditional equipment makes it difficult for operators to move it to a suitable position for welding and cutting operations, which seriously affects the smooth progress of the work.
[0008] With the increasing demands for welding and cutting quality and efficiency in industrial production, and the growing complexity and diversity of working environments, the market urgently needs an automated device that can overcome the above-mentioned shortcomings, has multi-dimensional adjustment functions, is lightweight and easy to move, highly adaptable, and can complete a variety of welding tasks. Therefore, this utility model proposes a multi-dimensional adjustable combined welding device. Utility Model Content

A swing handle rope 74 is mounted on the swing handle drive wheel 73, and the swing handle rope 74 passes through the guide shaft 75 and is fixed to the surface of the swing handle wheel 77. This allows the swing handle motor 72 to drive the swing handle drive wheel 73 to rotate in both directions when the swing handle motor 72 starts, thereby achieving forward and reverse pulling of the swing handle rope 74 on the swing handle wheel 77, and thus achieving forward and reverse pulling of the swing handle wheel 77. The swing arm 76 is rotated. An inner shaft 79 is rotatably mounted on the inner side of the frame plate 71 relative to the bottom of the thread guide shaft 75. An angle motor 78 is fixed on the inner side of the frame plate 71 relative to the left side of the inner shaft 79. A bevel gear 781 is installed at the output end of the angle motor 78. A bevel gear 791 that meshes with the bevel gear 781 is installed at the rear end of the inner shaft 79. A worm gear 792 is installed on the front surface of the inner shaft 79. A worm gear 751 that meshes with the worm gear 792 is installed on the surface of the thread guide shaft 75. This allows the angle motor 78 to drive the inner shaft 79 to rotate after it is started. The inner shaft 79 then drives the thread guide shaft 75 to rotate through the meshing of the bevel gear 791 and the bevel gear 781, as well as the meshing of the worm gear 792 and the worm gear 751. This enables the swing arm 76 to rotate. A welding gun head 8 is fixedly mounted on one side of the swing arm wheel 77.
[0037] In this embodiment, preferably, the flexible adjustable wire feeding mechanism assembly 9 includes an L-shaped top plate 91 rotatably mounted on the top of the swing arm frame 76, a side plate 92 fixed to one side of the L-shaped top plate 91, a welding wire feeding tube 93 mounted on the side plate 92, a swing plate support 94 fixed to the inner side of the L-shaped top plate 91, and a fan-shaped swing plate 95 rotatably mounted on the side of the swing plate support 94. The top end of the welding wire feeding tube 93 is fixed to the fan-shaped swing plate 95, so that the top end of the welding wire feeding tube 93 can rotate with the fan-shaped swing plate 95 to achieve angle adjustment. The top of the L-shaped top plate 91 is threaded with a compression spring 97, and the front end of the compression spring 97 is hinged to the fan-shaped swing plate 95. The rear end of the compression spring 97 extends through to the side of the L-shaped top plate 91 and is screwed with a wing nut 98. The surface of the threaded rod 96 is also fitted with a compression spring 97 between the fan-shaped swing plate 95 and the L-shaped top plate 91. When the operator rotates and turns the wing nut 98, it can drive the threaded rod 96 to move horizontally, so that the threaded rod 96 pulls the fan-shaped swing plate 95 to rotate up and down, so as to meet different angle adjustments.
[0038] In this embodiment, preferably, a shaft block 911 is provided between the L-shaped top plate 91 and the swing handle frame 76, so that the L-shaped top plate 91 can be smoothly rotated and adjusted on the top of the swing handle frame 76. Multiple adjusting bolts 912 are also installed on the top of the L-shaped top plate 91, and an arc-shaped slide is provided on the top surface of the L-shaped top plate 91 to match the adjusting bolts 912. The bottom end of the adjusting bolts 912 passes through the arc-shaped slide and is locked and fixed to the swing handle frame 76. Subsequently, the adjusting bolts 912 can be loosened to release the limitation on the L-shaped top plate 91, so that the L-shaped top plate 91 can be rotated on the top of the swing handle frame 76. After adjusting to a suitable angle, the adjusting bolts 912 can be tightened again to achieve multi-dimensional adjustment.
[0039] In summary, when using this device, the equipment is set up in the welding area, the welding torch head 8 is installed on the swing wheel 77, and the welding wire feed tube 93 is installed on the fan-shaped swing plate 95. The equipment can then be started for welding. When the lifting reduction motor 52 is started, it can drive the lifting platform 3, the swing handle and throttle assembly 7, and the flexible adjustable wire feeding mechanism assembly 9 to move vertically. Then, after the rack and pinion reduction motor 65 is started, it can drive the chain rack 61 to extend horizontally, thereby adjusting the horizontal position of the swing handle and throttle assembly 7 and the flexible adjustable wire feeding mechanism assembly 9. After the swing handle motor 72 is started, it can drive the swing wheel 77 to swing, thereby swinging the welding torch head 8. After the angle motor 78 is started, it can drive the swing handle frame 76 to rotate around the wire feed shaft 75. During welding, the angle motor 78 can also be turned to adjust the angle of the welding wire feed tube 93, and the horizontal rotation adjustment of the L-shaped top plate 91 can also be adjusted by rotating the adjusting bolt 2 912. This satisfies the requirements of automated welding while achieving multi-dimensional adjustment.
