Description
Technical Field
[0001] This utility model belongs to the technical field of welding positioning devices, and in particular relates to a welding positioning device for steel components. Background Technology
[0002] In the modern construction, bridge engineering, and heavy equipment manufacturing industries, steel structures have become a core load-bearing system due to their advantages of high strength, lightweight, and modular construction. Welding, as a key process for connecting steel components, directly determines the weld quality, structural mechanical properties, and engineering safety and reliability through its positioning accuracy. Therefore, high-efficiency welding positioning devices are core equipment for ensuring the quality of steel structure manufacturing.
[0003] However, existing welding positioning devices are not convenient for splicing two steel components, requiring repeated manual adjustments, which increases the labor intensity of operators, increases fatigue errors caused by manual operation, and reduces the efficiency and stability of splicing operations. Utility Model Content
[0004] The purpose of this utility model is to provide a steel component welding positioning device. By setting up a splicing part, it solves the problem that existing welding positioning devices are inconvenient to splice two steel components during use, requiring repeated manual adjustments, which increases the labor intensity of operators, increases fatigue errors caused by manual operation, and reduces the efficiency and stability of splicing operations.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a welding positioning device for steel components, comprising a hollow plate, and further comprising: a support portion disposed on the hollow plate; an assembly portion mounted on the hollow plate; a positioning portion comprising a plurality of positioning portions arranged in a circumferential array on the hollow plate; the assembly portion comprising an extrusion assembly disposed on the hollow plate; and a driving assembly mounted on the hollow plate; the extrusion assembly comprising two U-shaped slide rails fixedly connected to the inner wall of the top of the hollow plate, each U-shaped slide rail having a sliding rod slidably connected to its inner wall, and the tops of each sliding rod being fixedly connected to... The hollow plate is equipped with two rectangular sliders, each with a pressure plate fixedly connected to its top. A guide is provided on the hollow plate. Two U-shaped slide rails are arranged in a circular array. Two positioning parts are mounted on a slide rod. The guide includes two guide grooves formed on the hollow plate, with their inner walls slidably connected to the two rectangular sliders. Both guide grooves communicate with the inner cavity of the hollow plate. Through the cooperation of the U-shaped slide rails, slide rod, rectangular sliders, pressure plate, and guide grooves, the extrusion assembly, under power, can drive the pressure plate closer to the steel component and apply extrusion force, providing direct extrusion for the assembly of the steel component.
[0006] Furthermore, the drive assembly includes a motor fixedly connected to the bottom of the hollow plate. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The top of the rotating shaft extends rotatably into the hollow plate. A gear is fixedly connected to the top extension of the rotating shaft. Two racks are slidably connected to the bottom inner wall of the hollow plate. Connecting members are installed on the two racks. Both racks mesh with the gear. The connecting members include connecting blocks fixedly connected to the top of the two racks respectively. The two connecting blocks are fixedly connected to the two sliding rods respectively on the side close to the corresponding sliding rod.
[0007] Furthermore, the support includes two steel components placed on top of the hollow plate, and several support legs are fixedly connected to the bottom of the hollow plate; the two steel components are in contact with each other on opposite sides and the two pressure plates are in contact with each other.
[0008] Furthermore, the positioning part includes a transmission assembly disposed on the hollow plate; and a positioning assembly mounted on the hollow plate. The transmission assembly includes a hinged rod hinged to a slide rod, with a rectangular rod hinged to the top of the hinged rod. A second guide groove is provided on the hollow plate. The second guide groove communicates with the inner cavity of the hollow plate, and its inner wall is slidably connected to the outer wall of the rectangular rod. By means of the hinged rod, the rectangular rod, and the second guide groove, the transmission assembly can convert the movement of the slide rod into the directional sliding of the rectangular rod, thereby transmitting power and providing guidance for the positioning assembly to approach the steel component.
[0009] Furthermore, the positioning component includes a bracket fixedly connected to the top of the rectangular rod, and a plurality of positioning rollers are rotatably connected to the inner wall of the bracket; the plurality of positioning rollers are arranged in a linear array, and the side of the plurality of positioning rollers closest to the corresponding steel component is in contact with the steel component. The positioning component can achieve center positioning of the steel component by contacting the linear array of positioning rollers supported by the bracket. At the same time, the positioning rollers can assist the steel component in moving during assembly and prevent it from shifting.
[0010] This utility model has the following beneficial effects: 1. By setting up an assembly section, during assembly, the drive component uses a motor as a power source, which drives the gear to rotate through the shaft. The gear and two racks mesh and transmit power to the slide rod of the extrusion component through the connecting block. The extrusion component uses the sliding limit of the slide rod by the U-shaped slide rail and the guiding action of a pair of rectangular sliders by the guide groove to make the slide rod drive the rectangular sliders and the top pressure plate stably approach the steel component. Finally, under the power drive of the drive component, the two pressure plates squeeze the two steel components towards the middle and fit them tightly together. There is no need for continuous manual force or repeated adjustment, which significantly reduces the manual labor input, reduces the labor intensity of operators, avoids fatigue errors caused by manual operation, and improves the efficiency and stability of the assembly operation. 2. By setting up a positioning unit, during positioning, the transmission component and the positioning component work together to achieve dynamic centering and auxiliary limiting of the steel component. The transmission component uses the movement of the slide rod as a trigger signal, and transmits the power of the slide rod to the rectangular rod through the hinge rod. The guide grooves guide the rectangular rod to move the positioning component precisely close to the steel component. The positioning component, supported by a linear array of positioning rollers, contacts the surface of the steel component to form a limit. Several positioning units are arranged in a circumferential array, which can clamp and position the steel component from multiple directions, ensuring that the two steel components are always in a coaxial or coplanar docking state, further ensuring welding quality and reducing welding defects caused by inaccurate positioning.

[0020] A specific application of this embodiment is as follows: In use, a steel component 112 of a specified specification is placed on top of a hollow plate 111. The motor 221 is turned on, and the motor 221 drives the gear 223 to rotate through the shaft 222. The gear 223 drives the two connecting blocks 225 to move closer to each other through two racks 224. The two connecting blocks 225 drive the two sliding rods 212 to move closer to each other under the limitation of the two U-shaped slide rails 211. Analyzing one positioning part 3, the others are similar. The corresponding U-shaped slide rail 211 will pull the rectangular rod 312 to slide on the inner wall of the guide groove 2 313 towards the corresponding steel component 112 through the hinge rod 311. In this way, the rectangular rods 312 of the two positioning parts 3 on the left side drive the positioning components 32 to move closer to each other simultaneously. The steel component 112 on the left is centered, and the rectangular rods 312 of the two positioning parts 3 on the right drive the positioning assembly 32 to move closer to the steel component 112 on the right to center it. At the same time, the two rectangular sliders 213 will move closer to each other as the two sliders 212 move closer to each other, thereby driving the two pressure plates 214 to move closer to each other. Then, as the four positioning assemblies 32 center the two steel components 112, the two pressure plates 214 will drive the two steel components 112 to move closer to each other and join together. The positioning rollers 322 in the positioning assembly 32 provide a basis for the movement of the steel component 112 with the two pressure plates 214 while being positioned. In this way, the positioning and splicing of the two steel components 112 are completed, and welding can then begin.
