Description

Technical Field

[0001] This utility model relates to the field of assembly machines, and in particular to an assembly machine for steel structure assembly. Background Technology

[0002] A steel assembly machine is a specialized piece of equipment used in steel structure manufacturing. It primarily positions, clamps, and spot-welds cut steel plates (such as flanges and webs) to assemble them into H-beams or other types of steel components. For gantry-type steel assembly machines, during steel structure assembly, conveyor rollers are used to lay the flanges flat, side support components are used to hold the webs upright, and then a lifting structure lowers pressure rollers to further fix and limit the webs. Subsequently, the flanges and webs are conveyed and spot-welded at the joints to complete the assembly.

[0003] In existing gantry-type assembly machines, the pressure rollers have annular grooves to press and limit the web plate, improving stability. However, the size of these grooves remains constant and cannot be adjusted according to the web plate thickness. For thicker web plates, the grooves are ineffective at limiting the pressure, while for thinner web plates, the limiting effect is reduced, affecting stability and resulting in poor performance. Furthermore, the pressure rollers can only change height with the lifting mechanism; their horizontal position cannot be adjusted, limiting their flexibility and adaptability. Utility Model Content

[0004] The main objective of this invention is to provide an assembly machine for steel structure assembly, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-4 As shown, an assembly machine for steel structure assembly includes a base 1, a conveyor roller 2 on the base 1, and a side support assembly 3 mounted on the base 1. A gantry frame 4 is fixed on the base 1, and a hydraulic cylinder 5 is mounted on the gantry frame 4. The lower end of the lifting shaft of the hydraulic cylinder 5 is connected to a lifting frame 6, and a clamping and limiting structure 7 is provided at the lower end of the lifting frame 6. Conveyor frames 8 are provided at both ends of the base 1, and auxiliary support rollers 9 are provided on the conveyor frames 8. The lifting frame 6 is movably mounted on the gantry frame 4.

[0020] When assembling steel structures using an assembly machine, the conveyor rollers 2 on the base 1 are used for horizontal transport of the wing plates in the steel structure. The auxiliary support rollers 9 on the conveyor frame 8 provide auxiliary support. The web plate is placed sideways on the wing plates, and the side support assembly 3 is adjusted to provide lateral support for the web plate. Then, the hydraulic cylinder 5 on the gantry frame 4 is activated, and the lifting shaft lowers the lifting frame 6, thereby lowering the clamping and limiting structure 7 to clamp and limit the upper end of the sideways web plate, ensuring the stability of the web plate. After the wing plates and side plates are transported to the welding station, spot welding is performed to initially ensure stability, and then subsequent full welding is carried out to complete the connection of the steel structure.

[0021] The side support assembly 3 includes a fixed base 301, a movable base 302, a mounting bracket 303, a support wheel 304, a first servo motor 305, and a second servo motor 306. The two movable bases 302 are movably mounted on the fixed base 301, and the fixed base 301 is fixed on the base 1. The mounting bracket 303 is set on the movable base 302. The support wheel 304 is rotatably mounted on the end of the mounting bracket 303. The first servo motor 305 and the second servo motor 306 are set at both ends of the fixed base 301. The fixed base 301 has two adjusting screws inside, which are respectively connected to the first servo motor 305 and the second servo motor 306, and the adjusting screws are connected to the movable base 302.

[0022] When using the side support assembly 3, first start the first servo motor 305 and the second servo motor 306 at both ends of the fixed base 301. The two movable bases 302 are moved to make room by the two adjusting screws respectively. After the web plate is placed, start the two servo motors again to control the movement of the movable bases 302 respectively, so that the support wheels 304 on the mounting frame 303 abut against the web plate.

[0023] According to the above implementation scheme, the pressing and limiting structure 7 includes a slide rail 701, a slide block 702, a fixing plate 703, a lead screw 704, an adjusting motor 705, and a limiting component 706. The slide rail 701 is installed at the lower end of the lifting frame 6, the slide block 702 is slidably installed on the slide rail 701, the fixing plate 703 is fixed at both ends of the slide rail 701, the lead screw 704 is set on the fixing plate 703 and passes through the slide block 702, the adjusting motor 705 is fixed on the fixing plate 703 and is connected to the lead screw 704, and the limiting component 706 is installed on the slide block 702.

[0024] When the web plate is pressed and limited, the position of the limiting component 706 is adjusted according to the position of the web plate. During adjustment, after the adjusting motor 705 is started, the lead screw 704 between the fixed plates 703 rotates and exerts a force on the slide 702. The slide 702 moves along the slide rail 701 and moves with the limiting component 706 until the adjustment is completed. Then the lifting frame 6 lowers with the pressing and limiting structure 7. The limiting component 706 presses and fixes the web plate. At the same time, the movement of the limiting component 706 is controlled to limit the upper end of the web plate after it is side-standing, so as to ensure the stability of the web plate when it moves.

[0025] The limiting assembly 706 includes a mounting plate 7061, a guide rail 7062, a pressure roller 7063, a limiting plate 7064, and a telescopic cylinder 7065. The guide rail 7062 is mounted on the mounting plate 7061, and the mounting plate 7061 is fixed on the slide block 702. The pressure roller 7063 is rotatably mounted on the mounting plate 7061. The limiting plate 7064 is slidably disposed on the guide rail 7062, and the limiting plate 7064 is provided with a round hole. The telescopic cylinder 7065 is fixed on the mounting plate 7061, and the telescopic shaft of the telescopic cylinder 7065 is connected to the limiting plate 7064.

[0026] When using the limiting component 706, the pressing roller 7063 presses against the web plate. After the telescopic cylinder 7065 is activated, the limiting plate 7064 moves on the guide rail 7062 to close to the web plate, thus limiting the web plate. When the web plate moves, the pressing roller 7063 rotates on the mounting plate 7061. Due to the circular hole on the limiting plate 7064, the pressing roller 7063 and the limiting plate 7064 are set independently and do not affect each other, ensuring that pressing and limiting are carried out simultaneously.

[0027] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
