Description

Technical Field

[0001] This invention relates to the field of bridge engineering, and in particular to an assembly tool for I-beam components and its method of use. Background Technology

[0002] As a core basic component in the field of steel structures, I-beams are widely used in various industries such as road and bridge construction, building construction, machinery manufacturing, and rail transit due to their reasonable structure, strong load-bearing capacity, and excellent mechanical properties. Their processing accuracy, structural strength, and stability directly affect the safety, reliability, and service life of the overall structure in various application scenarios, and must meet the accuracy control standards in large-scale production.

[0003] In the field of I-beam component processing and manufacturing, most I-beam components are assembled using welding processes. The specific processing flow is as follows: First, using specialized welding positioning fixtures, the multiple steel plate parts that make up the I-beam component are precisely spliced ​​and positioned. Then, the fixtures are used to clamp and fix each part one by one to ensure that each component fits tightly and that the positional deviation meets the standards. After completing the welding operation on one side, the initially formed I-beam component needs to be flipped over to perform welding operations on the other side to ensure that the weld is complete and the structure is solid.

[0004] Due to the large weight of the steel structure panels, manual handling and assembly are difficult. Uncertainty during assembly by workers can easily lead to positioning deviations, which directly affect processing accuracy and structural stability.

[0005] Therefore, it is necessary to develop new I-beam assembly tooling and its usage methods to solve the technical problems of difficult precision control and cumbersome assembly process in the existing technology. Summary of the Invention

[0006] Purpose of the invention: To address the shortcomings and defects of existing technologies, this invention provides an assembly tooling for I-beam components and its usage method, solving the technical problems of difficult precision control and cumbersome assembly process during the assembly of I-beam components. The adjustable constraint system can be widely used to assemble I-beam components of various specifications and types. It has a simple structure, is easy to operate, and can effectively improve assembly accuracy and construction efficiency while saving costs.

[0007] Technical solution: The present invention provides an assembly tooling for I-beam components, characterized in that it includes a base, a web and stiffening positioning assembly, a web and stiffening sliding positioning assembly, a top three-way limiting block, and a bottom sliding positioning assembly; the base is provided with the web and stiffening positioning assembly, the top three-way limiting block, the web and stiffening sliding positioning assembly, and the bottom sliding positioning assembly in sequence around its perimeter; the web and stiffening sliding positioning assembly and the bottom sliding positioning assembly are provided with slide rails.

[0008] The base tire is a basic load-bearing structure that integrates various limiting components, transfers the weight of components, and ensures the overall stability of the tooling. The upper and lower surfaces of the base tire are treated to be ultra-flat.

[0009] The web plate and stiffening positioning assembly are single-sided fixed positioning components that limit the position of the web plate on one side of the I-shaped component to prevent lateral displacement during assembly.

[0010] The web plate and stiffening sliding positioning assembly are adjustable positioning components. By adjusting the spacing, they can adapt to I-shaped components of different widths and flexibly limit the position of the web plate on the other side, ensuring symmetrical positioning on both sides. A slide rail is also provided to provide space for the I-shaped component to be unloaded.

[0011] The top three-way limiting block is an upper constraint component that restricts the vertical displacement of the top parts of the I-shaped component and prevents them from moving upwards during assembly.

[0012] The bottom sliding positioning component is a lower constraint component that fits the bottom contour of the I-shaped component, limits the longitudinal installation position, and cooperates with the top three-way limiting block to form a two-way constraint, improving assembly stability. It is also equipped with a slide rail to provide space for the I-shaped component to be unloaded.

[0013] The method of using the I-shaped component assembly fixture of the present invention is characterized by comprising the following steps:

[0014] 1) Install the lower flange plate of the I-shaped component, and restrict the vertical, lateral and longitudinal displacement of the lower flange plate by means of the base plate, web plate and stiffening positioning components and the top three-way limiting block respectively;

[0015] 2) Install the top plate of the I-shaped component, restrict the vertical displacement of the top plate by the lower flange plate, and restrict the lateral and longitudinal displacement of the top plate by the top three-way limiting blocks;

[0016] 3) Install the web of the I-shaped component. The vertical displacement of the web is restricted by the lower flange plate, the longitudinal displacement of the web is restricted by the top plate, and the lateral displacement of the web is restricted by the web and the stiffening positioning assembly. After the web is placed, push the web and the stiffening sliding positioning assembly to clamp and fix the web to prevent the web from tilting.

[0017] 4) Install web stiffeners for I-shaped components, restricting the vertical displacement of the web stiffeners by the lower flange plate, restricting the longitudinal displacement of the web stiffeners by the web plate and stiffener positioning components, and restricting the lateral displacement of the web stiffeners by the web plate.

[0018] 5) Install the upper flange plate of the I-shaped component, restrict the vertical displacement of the upper flange plate by the web plate, restrict the longitudinal displacement of the upper flange plate by the top three-way limiting block, and restrict the lateral displacement of the upper flange plate by the web plate and stiffening positioning assembly.

[0019] 6) Install the base plate of the I-shaped component, restrict the vertical, horizontal and longitudinal displacement of the base plate by the bottom sliding positioning component, and then push the slide rail of the bottom sliding positioning component to make the base plate of the I-shaped component fit tightly against the I-shaped component;

[0020] 7) After the I-shaped component is installed as a whole, push the slide rail of the bottom sliding positioning component and the slide rail of the web plate and the stiffening sliding positioning component to unload the I-shaped component.

[0021] The web and stiffening positioning assembly are T-shaped structures.

[0022] The web plate and stiffening sliding positioning assembly are provided with two slide rails at the bottom.

[0023] The bottom sliding positioning component has two slide rails at its bottom.

[0024] Beneficial Effects: Compared with existing technologies, this invention has the following significant advantages: This invention connects the various parts of the system through welding and sliding rails to form a constraint system. During the assembly of the I-shaped components, no relative displacement occurs within this constraint system, and after assembly, the I-shaped component can be separated from the constraint system simply by moving the sliding rails. This solves the technical problems of difficult precision control and cumbersome assembly processes in existing technologies. This system can be used for the assembly of various types of I-shaped components, has a simple structure, is convenient to use, improves construction efficiency, and has extremely high practical and promotional value. It can be widely used in the manufacture of steel structure products. Attached Figure Description

Detailed Implementation

[0041] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] like Figures 1 to 6 The present invention provides an assembly tooling for I-beam components, comprising a base 1, a web plate and stiffening positioning assembly 2, a web plate and stiffening sliding positioning assembly 3, a top three-way limiting block 4, and a bottom sliding positioning assembly 5; the base 1 is provided with the web plate and stiffening positioning assembly 2, the top three-way limiting block 4, the web plate and stiffening sliding positioning assembly 3, and the bottom sliding positioning assembly 5 in sequence around its perimeter; the web plate and stiffening sliding positioning assembly 3 and the bottom sliding positioning assembly 5 are provided with slide rails.

[0043] The base plate 1 is the basic load-bearing structure of this tooling, serving to integrate various limiting components, transfer the weight of components, and ensure the overall stability of the tooling, providing a flat and reliable working benchmark for the assembly of I-beam components. The upper and lower surfaces of the base plate 1 need to be made ultra-flat.

[0044] The web plate and stiffening positioning assembly 2 is a single-sided fixed positioning component, which plays a role in accurately defining the position of the web plate 8 on one side of the I-shaped component, avoiding lateral displacement during assembly, and ensuring the positioning accuracy of the core component.

[0045] The web plate and stiffening sliding positioning assembly 3 are adjustable positioning components. By adjusting the spacing, they can adapt to I-shaped components of different widths and specifications, flexibly limiting the position of the web plate 8 on the other side, ensuring symmetrical positioning on both sides, and providing space for the I-shaped components to be unloaded and installed.

[0046] The top three-way limiting block 4 is an upper constraint component, which restricts the vertical displacement of the top parts of the I-shaped component, prevents them from moving upwards during assembly, and ensures accurate vertical positioning of the component.

[0047] The bottom sliding positioning component 5 is a lower constraint component, which fits the bottom contour of the I-shaped component and limits the longitudinal installation position. It works with the top three-way limiting block 4 to form a two-way constraint from top to bottom, improving the assembly stability. It is also equipped with a slide rail to provide space for the I-shaped component to be unloaded.

[0048] The method of using the I-shaped component assembly fixture of the present invention is characterized by comprising the following steps:

[0049] 1) The lower flange plate 6 of the I-beam component is installed, and its vertical, lateral, and longitudinal displacements are restricted by the base plate 1, the web plate and stiffening positioning assembly 2, and the top three-way limiting block 4, respectively; (e.g.) Figure 7 )

[0050] 2) The top plate 7 of the I-shaped component is installed, and the vertical displacement of the top plate 7 is restricted by the lower flange plate 6, and the lateral and longitudinal displacement of the top plate 7 is restricted by the top three-way limiting blocks 4; (e.g.) Figure 8 )

[0051] 3) Install the web plate 8 of the I-beam component. The vertical displacement of the web plate 8 is restricted by the lower flange plate 6, the longitudinal displacement of the web plate 8 is restricted by the top plate 7, and the lateral displacement of the web plate 8 is restricted by the web plate and stiffening positioning assembly 2. After the web plate 8 is placed, push the web plate and stiffening sliding positioning assembly 3 to clamp and fix the web plate 8 to prevent it from tipping over; (e.g.) Figure 9 , Figure 10 )

[0052] 4) Install the web stiffener 9 of the I-beam component. The vertical displacement of the web stiffener 9 is limited by the lower flange plate 6, the longitudinal displacement of the web stiffener 9 is limited by the web and stiffening positioning assembly 2, and the lateral displacement of the web stiffener 9 is limited by the web plate 8; (e.g.) Figure 11 )

[0053] 5) Install the upper flange plate 10 of the I-beam component. The vertical displacement of the upper flange plate 10 is restricted by the web plate 8, the longitudinal displacement of the upper flange plate 10 is restricted by the top three-way limiting block 4, and the lateral displacement of the upper flange plate 10 is restricted by the web plate and stiffening positioning assembly 2; (e.g.) Figure 12 )

[0054] 6) Install the base plate 11 of the I-shaped component, restrict the vertical, horizontal, and longitudinal displacement of the base plate 11 by means of the bottom sliding positioning component 5, and then push the slide rail of the bottom sliding positioning component 5 to make the base plate 11 of the I-shaped component fit tightly against the I-shaped component; (e.g.) Figure 13 , Figure 14 )

[0055] 7) After the I-beam component is fully installed, push the slide rail of the bottom sliding positioning component 5 against the slide rail of the web plate and the stiffening sliding positioning component 3 to unload the I-beam component. (e.g.) Figure 15 )

[0056] The I-beam assembly fixture of this invention is adaptable to the assembly of I-beams of various specifications and types. During use, only the positioning parameters need to be adjusted once according to the dimensions of the I-beam to provide stable constraints for each steel plate part, ensuring no relative displacement during assembly. Furthermore, after assembly, the I-beam can be easily separated from the fixture simply by moving the slide rail, without affecting the quality of the component.

[0057] The assembly fixture and method for I-beam components provided by this invention are specifically optimized to address the core common pain points of existing I-beam component processing technology. It is applicable to the assembly of I-beam components of different specifications and types. This invention uses a guardrail post as a typical example for detailed explanation. The fixture system has a simple and compact structure, requiring no complex operation training for quick mastery. Furthermore, positioning parameters can be quickly adjusted according to the size and specifications of the I-beam components, significantly improving the equipment's versatility and adaptability, breaking the limitation of traditional fixtures that are only applicable to single types and specifications of components. In practical applications, this fixture, through its precise mechanical positioning structure, effectively reduces human error in manual assembly, raising the assembly positioning accuracy of I-beam components to a higher standard, ensuring the stability of each component's position during welding, thereby improving weld quality and overall structural strength. Simultaneously, its structure allows for direct double-sided welding, eliminating the need for manual handling and flipping of the formed I-beam components, significantly reducing the labor intensity of workers, shortening the processing cycle of a single I-beam component, and greatly improving construction efficiency.
