Description

Technical Field

[0001] This utility model relates to the technical field of space frame welding, and in particular to a welding device for large-span, multi-layer, irregularly shaped space frames. Background Technology

[0002] Large-span, multi-layered irregular-shaped space frame is a three-dimensional spatial structure composed of interwoven steel components with multi-curved geometric shapes. It combines lightweight and high load-bearing characteristics and is widely used in large public buildings such as stadiums and convention centers to achieve the integration of open column-free space and aesthetic design.

[0003] Existing metal mesh welding devices, such as the one disclosed in utility model patent application number 202323338676.5, mainly include a base plate. Four sets of mounting seats are symmetrically arranged on the top of the base plate, each mounting seat is connected to a driving device. A rectangular block is connected to the driving device. A bearing plate is fixedly mounted on the top of the rectangular block, and a second bearing plate is in close contact with the side wall of the first bearing plate. A hinge is fixedly installed between the second bearing plate and the first bearing plate. A limit block is fixedly installed at the bottom of the first bearing plate. In use, when the metal mesh being processed is rectangular, the handle is pulled sequentially, causing the handle to move the round rod away from the limit block. Simultaneously, the second bearing plate is pushed downwards, causing the horizontally positioned second bearing plate to rotate to a negative angle via the hinge. At this point, a rectangular metal mesh can be processed on the first bearing plate. When the metal mesh being processed is circular, the above operation is reversed.

[0004] However, large-span, multi-layer, irregularly shaped space frames are three-dimensional structures. During the welding process, the welding torch needs to be inserted into different layers of the space frame for welding, which is very troublesome. Moreover, the space frame has a large span, so the position of the welding machine needs to be constantly adjusted. Most existing welding machines are fixedly installed, making it difficult to complete the welding task of large-span space frames. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a welding device for large-span multi-layer irregular space frame that can not only drive the welding machine to move, making it easy to adapt to the large span of the space frame, but also drive the welding torch to move back and forth, making it easy to extend into the space frame between different levels.

[0006] This utility model discloses a welding device for a large-span, multi-layer, irregularly shaped space frame, including a moving mechanism; it also includes a support mechanism, a driving mechanism, a telescopic mechanism, and a welding mechanism.

The sliding slider slides on the two sets of guide rails, which facilitates welding at different positions of the grid frame. Welding efficiency can be improved by increasing the number of sliding sliders, and collisions between adjacent sets of sliding sliders can be avoided by setting springs and anti-collision pads.

[0008] Preferably, the support mechanism includes a support frame, two sets of lead screws, a lifting block, a rack, and a positioning plate. The bottom end of the support frame is connected to the top end of the movable slider. Both sets of lead screws are rotatably mounted on the support frame.

The two sets of lead screws drive the lifting block to rise and fall, adjusting the welding height. The telescopic mechanism meshes with the rack, driving the rack to move back and forth, facilitating insertion into different layers of the space frame for welding. The positioning plate prevents the rack from falling off.

[0009] Preferably, the drive mechanism includes a first servo motor, a dual-output shaft reducer, a transmission shaft, and a right-angle steering gear.

The output end of the transmission shaft is connected to the input end of the right-angle steering gear, and the output end of the right-angle steering gear is connected to the input end of the second set of lead screws. When the first servo motor is started, it drives the transmission shaft and the first set of lead screws to rotate through the dual-output shaft reducer. The transmission shaft drives the second set of lead screws to rotate through the right-angle steering gear, and the two sets of lead screws rotate synchronously.

[0010] Preferably, the telescopic mechanism includes a second servo motor, a reducer, and a toothed roller.

The output end of the reducer is connected to the input end of the toothed roller, and the toothed roller meshes with the rack for transmission. When the second servo motor is started, the second servo motor drives the toothed roller to rotate through the reducer.
