Description
Technical Field
[0001] This utility model relates to the technical field of steel structure assembly tools, and in particular to a device for assembling steel structures. Background Technology
[0002] Steel structures are widely used in construction, bridges and other fields due to their high strength and large span. As a key process in steel structure manufacturing, the accuracy of assembly directly affects the subsequent welding quality and structural stability. With the increasing demand for large steel structures, traditional manual assembly or simple equipment can no longer meet the requirements of high precision and high efficiency, and there is an urgent need for automated assembly equipment to improve production levels. Existing steel structure assembly devices have significant drawbacks. Traditional devices typically consist of a fixed base plate, simple clamping plates, and manually adjustable components. The clamping plates can only hold a single specification of steel structure, requiring disassembly and reassembly when changing specifications. When assembling steel sections with different cross-sections, repeated adjustments to the clamping position are necessary, making the operation cumbersome. The lack of multi-directional clamping structures means that relying solely on clamping from both sides can easily lead to vertical displacement of the steel structure, resulting in low assembly accuracy. Furthermore, the absence of automatic cleaning functions causes welding waste and coolant to accumulate on the base plate, requiring frequent manual cleaning and impacting production continuity. The feeding and assembly actions are not synchronized, necessitating manual assistance in pushing the steel structure, which is inefficient. Ultimately, this leads to poor adaptability and low efficiency. Therefore, this application designs a steel structure assembly device to address these problems. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for assembling steel structures.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a steel structure assembly device, comprising a base plate, two side plates mounted on both sides of the upper end of the base plate, multiple feed rollers rotatably mounted between the two side plates, and a welding assembly for welding steel structures. Two sliding plates are slidably mounted opposite each other between the two side plates. A bracket is mounted on the upper end of the base plate, and an mounting plate is slidably mounted on the inner side of the bracket. Two support plates are symmetrically provided on the lower end of the mounting plate. Connecting plates are installed between the outer sides of the two support plates and the lower ends of the mounting plate. A second electric actuator is mounted on the upper end of the bracket, and the output end of the second electric actuator is fixedly connected to the upper end of the mounting plate.
[0005] Preferably, a first clamping plate is installed on the upper end of each of the two sliding plates, and two first electric actuators are symmetrically installed on the inner wall of the side plate at the upper end of the two first clamping plates, with an installation block installed on the output end of the first electric actuator.

[0007] Preferably, a scraper is installed at the lower end of the sliding plate, and a plurality of channels are provided at the upper end of the base plate for discharging welding waste or coolant.
[0008] Preferably, the lower end of the mounting plate is provided with a guide groove, a first bidirectional lead screw is rotatably installed inside the guide groove, two sliders are slidably installed in opposite directions inside the guide groove, the two sliders are respectively threaded to both ends of the first bidirectional lead screw, and a second clamping plate is installed at the lower end of each of the two sliders.
[0009] Preferably, a second motor is installed on the side end of the mounting plate, and the output shaft of the second motor is coaxially fixed to the first bidirectional lead screw. A sliding groove is opened on the inner side of both support plates, and a third clamping plate is slidably installed inside the sliding groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model utilizes a first motor in conjunction with a second bidirectional lead screw, a sliding plate, and a first clamping plate. The first motor drives the second bidirectional lead screw to move the sliding plate and the first clamping plate in opposite directions, adapting to steel structures of different widths, facilitating precise lateral clamping, improving adaptability, and thus achieving flexible lateral clamping. Furthermore, the second motor, in conjunction with the first bidirectional lead screw, a slider, and a second clamping plate, drives the first bidirectional lead screw to adjust the spacing of the second clamping plate. Combined with a third electric push rod to push the third clamping plate, this facilitates multi-position longitudinal clamping. This system provides support to prevent steel structure shifting, improves assembly accuracy, and achieves precise longitudinal clamping. Through the cooperation of a scraper, sliding plate, and through-slot, the sliding plate moves, driving the scraper to clean the bottom plate. Waste and coolant are discharged through the through-slot, facilitating automatic cleaning, reducing manual intervention, improving production continuity, and achieving automatic waste removal. Furthermore, through the cooperation of a second electric actuator with the mounting plate and support plate, the second electric actuator adjusts the height of the support plate to assist in supporting the steel structure, facilitating adaptation to workpieces of different heights, improving assembly stability, and achieving flexible support. Ultimately, this solves the problems of poor adaptability and low efficiency of existing devices. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Example: See Figures 1 to 4This utility model discloses a steel structure assembly device, comprising a base plate 1, two side plates 2 mounted on both sides of the upper end of the base plate 1, multiple feed rollers 3 rotatably mounted between the two side plates 2, and welding components for welding the steel structure; two sliding plates are slidably mounted opposite each other between the two side plates 2; a bracket 5 is mounted on the upper end of the base plate 1, and an mounting plate 10 is slidably mounted on the inner side of the bracket 5; two support plates are symmetrically arranged on the lower end of the mounting plate 10; connecting plates are installed between the outer sides of the two support plates and the lower ends of the mounting plate 10; a second electric actuator 6 is mounted on the upper end of the bracket 5, and the output end of the second electric actuator 6 is fixedly connected to the upper end of the mounting plate 10; the base plate 1 provides the installation foundation, the feed rollers 3 transport the steel structure, the sliding plates drive the clamping components to adjust their position, and the second electric actuator 6 controls the lifting and lowering of the mounting plate 10 and the support plates. The support plate assists in supporting the steel structure, ensuring assembly stability. A first clamping plate 7 is installed on the upper end of each of the two sliding plates. Two first electric push rods 4 are symmetrically installed on the inner walls of the side plates 2 at the upper end of the two first clamping plates 7. An installation block is installed at the output end of each first electric push rod 4. The guide rollers of the first clamping plates 7 and the first electric push rods 4 clamp the steel structure from both sides, reducing conveying resistance, preventing steel structure displacement, and improving assembly accuracy. A first motor 11 is installed on the outer side of one of the side plates 2. A second bidirectional lead screw is rotatably installed between the two side plates 2. The side ends of the two sliding plates are threaded to both ends of the second bidirectional lead screw. The output shaft of the first motor 11 is coaxially fixed to the second bidirectional lead screw. The first motor 11 drives the second bidirectional lead screw to move the sliding plates in opposite directions, adjusting the spacing of the first clamping plates 7 to adapt to steel structures of different widths and improve the device's adaptability.
[0015] In this invention, a scraper 8 is installed at the lower end of the sliding plate, and multiple through grooves 9 are provided at the upper end of the base plate 1 for discharging welding waste or coolant. When the sliding plate moves, it drives the scraper 8 to clean the waste and coolant on the surface of the base plate 1. The waste is discharged through the through grooves 9, keeping the base plate 1 clean, reducing manual cleaning work, and improving production efficiency. A guide groove is provided at the lower end of the mounting plate 10. A first bidirectional lead screw 15 is rotatably installed inside the guide groove, and two sliders are slidably installed opposite each other inside the guide groove. The two sliders are threaded to both ends of the first bidirectional lead screw 15, and a second clamping plate 14 is installed at the lower end of each slider. The first bidirectional lead screw 15 drives the sliders and the second clamping plate 14 to move, clamping the steel structure longitudinally. Guide rollers assist in conveying, preventing longitudinal displacement of the steel structure, and improving the stability of the assembly. Qualitatively, a second motor 12 is installed on the side of the mounting plate 10. The output shaft of the second motor 12 is coaxially fixed to the first bidirectional lead screw 15. Sliding grooves are opened on the inner sides of both support plates. A third clamping plate is slidably installed inside the sliding grooves. A third electric push rod 13 is installed between the third clamping plate and the inner wall of the sliding groove. Multiple guide rollers are equidistantly rotatably installed on the inner sides of the two first clamping plates 7, the inner side of the mounting block, the inner side of the second clamping plate 14, and the side of the third clamping plate. The second motor 12 drives the first bidirectional lead screw 15 to rotate, and the third electric push rod 13 pushes the third clamping plate to slide, further adjusting the clamping position to adapt to steel structures of different heights and enhance clamping flexibility. The motors used in this device are all YD series variable speed motors, and the electric push rods used are all LA-T8 series electric push rods.
[0016] Working principle: When using this utility model, firstly, the power is turned on. Then, according to the specifications of the steel structure to be assembled, the first motor 11 installed on the outside of one of the side plates 2 is started. The output shaft of the first motor 11 drives the second bidirectional lead screw rotatably installed between the two side plates 2 to rotate, thereby driving the two sliding plates threaded to both ends of the second bidirectional lead screw to move in opposite directions, thereby adjusting the distance between the first clamping plates 7 installed at the upper end of the two sliding plates to match the width of the steel structure. Next, the second motor 12 on the side of the mounting plate 10 is started. The output shaft of the second motor 12 drives the first bidirectional lead screw 15 rotatably installed inside the guide groove at the lower end of the mounting plate 10 to rotate, so that... Two sliders, which slide opposite each other in the guide groove and are threaded to both ends of the first bidirectional lead screw 15, move synchronously, thereby driving the second clamping plate 14 installed at the lower end of the two sliders to adjust to the appropriate longitudinal clamping position; then, the second electric push rod 6 installed at the upper end of the bracket 5 is activated, and the output end of the second electric push rod 6 pushes the mounting plate 10 slidably installed inside the bracket 5 and the support plate symmetrically arranged at the lower end of the mounting plate 10 to descend together to the position adapted to the height of the steel structure; then, the third electric push rod 13 installed between the inner wall of the sliding groove of the support plate and the third clamping plate is activated, and the third electric push rod 13 pushes the third clamping plate slidably installed inside the sliding groove to move to fit the surface of the steel structure; complete. After the above adjustments, the steel structure is placed on multiple feed rollers 3 rotatably mounted between the two side plates 2. The feed rollers 3 drive the steel structure to the assembly area. At the same time, two first electric actuators 4 symmetrically mounted on the inner walls of the upper side plates 2 of the two first clamping plates 7 are activated. The output ends of the first electric actuators 4 push the mounting block to drive the guide rollers on their inner sides to press down, clamping the steel structure from both the top and bottom sides together with the guide rollers on the inner sides of the first clamping plates 7. Meanwhile, the second clamping plate 14 and the third clamping plate provide auxiliary clamping of the steel structure from the longitudinal direction, effectively preventing the steel structure from shifting during the conveying process. After the steel structure is conveyed to the designated assembly position and the assembly is completed, the system is then activated. The welding components used for welding the steel structure weld the steel structure. During the welding process, the welding waste and coolant generated are simultaneously swept by the scraper 8 installed at the lower end of the sliding plate to multiple through slots 9 opened at the upper end of the base plate 1 as the sliding plate moves. Then, the waste is discharged into the waste collection point below the device through the through slots 9. After the welding operation is completed, the first motor 11, the second motor 12, the first electric push rod 4, the second electric push rod 6, and the third electric push rod 13 are started in reverse to release the steel structure from the clamping components. At this time, the steel structure is conveyed to the next production process under the conveying action of the feed roller 3. Finally, the power supply of the device is turned off, thus completing the entire steel structure assembly operation process.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
