A high-precision assembly machine for steel structures

Abstract

A high-precision steel structure assembly machine uses an exhaust fan to draw welding fumes into a filter box. After being filtered through a filter screen, the fumes fall into a dust collection box, effectively removing welding fumes and significantly improving the working environment. This reduces health hazards to operators, as welding fumes not only pollute the environment but also impair visibility, thus affecting welding quality. This device, through its efficient fume treatment system, ensures clean air in the welding area, improving visibility and contributing to consistent welding quality. Welding fumes pose a threat to operator health; long-term inhalation can lead to respiratory illnesses. This device, with its efficient fume treatment system, effectively reduces fume dispersion, lowers the risk of occupational diseases for operators, and enhances overall operational safety.

Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a high-precision assembly machine for steel structures. Background Technology

[0002] Steel structures, due to their significant advantages such as high strength, light weight, good seismic performance, and fast construction speed, have been widely used in many fields such as construction, bridges, and machinery manufacturing. In the steel structure manufacturing process, the assembly process is one of the key steps, and its precision and quality directly affect subsequent welding and the performance and stability of the entire steel structure product. As the core equipment for achieving efficient and accurate steel structure assembly, the performance of high-precision assembly machines is of paramount importance.

[0003] Chinese patent application CN202021661909.9 discloses a high-precision assembly machine for steel structures, including a base plate with a hydraulic column fixedly connected to the top and center of the base plate. This high-precision assembly machine uses a rotating motor to drive a moving plate forward, which in turn drives a T-shaped clamping device forward to align T-shaped steel sections with I-shaped steel sections. A second moving plate then drives the I-shaped clamping device to the left to splice the T-shaped steel sections with the I-shaped steel sections. This improves work efficiency and the quality of steel section splicing. Machine operation reduces personnel injuries and equipment damage. By coordinating the T-shaped and I-shaped clamping devices, different specifications of T-shaped steel sections and different specifications of I-shaped steel sections can be clamped, and different specifications of I-beams can be assembled, reducing worker workload and increasing steel production efficiency.

[0004] However, existing assembly machines still have some shortcomings. They lack effective fume treatment devices during the welding process. The fumes generated during welding not only pollute the working environment and endanger the health of operators, but also affect the clarity of the welding line of sight, thus affecting the stability of welding quality.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0017] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0018] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0019] like Figures 1 to 5 As shown, a high-precision assembly machine for steel structures includes a conveyor frame 1 and a conveyor frame 2. A support base 3 is connected between opposite sides of the conveyor frame 1 and the conveyor frame 2. A support frame 4 is installed on the upper surface of the support base 3. Welding mechanisms 5 are symmetrically installed on the support frame 4. A filter box 6 is installed on the upper surface of the support frame 4. A drive mechanism 7 is installed on one side of the conveyor frame 1. An auxiliary mechanism 10 is installed on the support frame 4. Multiple guide mechanisms 8 are installed in pairs on the upper surface of the conveyor frame 1. A fixing mechanism 9 is installed on one side of the guide mechanism 8. A fan 601 is installed at the top of the filter box 6. A suction pipe 602 is connected to one side of the filter box 6. A suction hood 603 is connected to the bottom of the suction pipe 602. A filter screen 604 is fitted on the suction pipe 602. A dust collection box 605 is located directly below the filter screen 604.

[0020] Through the above solution, during the welding process, the exhaust fan 601 is activated, generating a strong suction force. The welding fumes are quickly drawn into the filter box 6 through the suction pipe 602 and the suction hood 603, effectively preventing the spread of fumes in the working environment, greatly improving the air quality of the working environment, providing operators with a relatively clean and healthy working space, reducing the risk of operators contracting respiratory diseases and other occupational diseases due to inhaling fumes, and protecting the health of operators.

[0021] The two welding mechanisms 5 include a drive motor 501 fixedly installed at the bottom of the support base 3. The output end of the drive motor 501 is connected to a threaded rod 502. Lifting blocks 503 are sleeved on both sides of the support frame 4. The threaded rod 502 is threadedly connected to the lifting block 503. Electric push rods 504 are installed on the opposite side of the lifting block 503. Welding heads 505 are fixedly installed on the extended end of the electric push rods 504.

[0022] Through the above scheme, the drive motor 501 drives the threaded rod 502 to rotate, causing the lifting block 503 to move up and down, thereby adjusting the height of the welding head 505. The electric push rod 504 can further fine-tune the horizontal position of the welding head 505, which can meet the welding requirements of steel structures of different specifications, ensure that the welding head 505 is in the optimal welding position, effectively improve welding accuracy and quality, and reduce welding defects.

[0023] The auxiliary mechanism 10 includes an electric push rod 1001 fixedly installed at the top of the support frame 4. The extended end of the electric push rod 1001 is fixedly connected to a mounting plate 1002. A guide wheel 1003 is installed in the middle of the lower surface of the mounting plate 1002. Pressure wheels 1004 are installed on both sides of the guide wheel 1003.

[0024] Through the above scheme, the electric push rod 802 drives the mounting frame 803 to move, and the guide roller 804 provides auxiliary guidance for the steel structure. Multiple sets of guiding devices work together to ensure the stability and accuracy of the steel structure during transportation, avoid the steel structure from shifting during transportation, and provide a guarantee for high-quality welding.

[0025] The drive mechanism 7 includes a rectangular groove 701 formed in the middle of the upper surface of the conveyor frame 1. Multiple rollers 702 are rotatably connected to the rectangular groove 701. A drive motor 703 is installed at one end of the conveyor frame 1. A rotating shaft 704 is connected to the output end of the drive motor 703. Multiple bevel gears 705 are installed on the rotating shaft 704. One end of the roller 702 passes through the conveyor frame 1 and is connected to a bevel gear 706. The bevel gears 705 and the bevel gears 706 mesh with each other.

[0026] Through the above scheme, drive motor 703 drives shaft 704 to rotate, and through the meshing transmission of bevel gear 705 and bevel gear 706, multiple rollers 702 rotate synchronously. This drive method can provide stable and uniform conveying power for the steel structure, ensuring that the steel structure moves smoothly on conveyor frame 1 and improving production efficiency.

[0027] The guiding mechanism 8 includes a pair of mounting plates 801 fixedly mounted on the upper surface of the conveyor frame 1. An electric push rod 802 is mounted on the mounting plate 801. The extended end of the electric push rod 802 is fixedly connected to a mounting bracket 803. A guide roller 804 is mounted on the mounting bracket 803.

[0028] Through the above scheme, the electric push rod 802 drives the mounting frame 803 to move, and the guide roller 804 provides auxiliary guidance for the steel structure. Multiple sets of guiding devices work together to ensure the stability and accuracy of the steel structure during transportation, avoid the steel structure from shifting during transportation, and provide a guarantee for high-quality welding.

[0029] The fixing mechanism 9 includes a connecting seat 901 symmetrically fixedly installed on the upper surface of the conveyor frame 1. An electric push rod 902 is installed on the connecting seat 901, and a fixing plate 903 is fixedly connected to the extended end of the electric push rod 902.

[0030] Using the above method, the electric push rod 902 pushes the fixing plate 903 to fix the steel structure. During the welding process, a stable fixation can effectively prevent the steel structure from shifting due to external forces or its own stress, ensuring the accuracy of the welding position and further improving the welding quality and the overall precision of the product.

[0031] Conveyor frame 1 and conveyor frame 2 have the same structure.

[0032] With the above design, conveyor frame 1 and conveyor frame 2 have identical structures. This design makes the production and maintenance of the equipment more convenient. During production, the same processes and molds can be used for manufacturing, reducing production costs. During maintenance, there is no need to distinguish between the different structures, reducing maintenance time and costs and improving the overall cost-effectiveness of the equipment.

[0033] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0034] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
