Detailed implementation manners

[0026] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In this specification, the orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned are defined with respect to the structures shown in the respective drawings. The terms "inside" and "outside" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may accordingly change depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0028] This embodiment provides a device for assembling H-shaped steel. Referring to Figures 1 to 4 , it includes a frame 1, a mounting seat 2, a first positioning mechanism 3 for positioning two flanges a in a first direction, and a second positioning mechanism 4 for positioning a web b in the first direction. The first positioning mechanism 3 is arranged on the frame 1, and the second positioning mechanism 4 is arranged on the mounting seat 2. Referring to Figure 1, the first direction is the up-and-down direction of the assembly device, the second direction is the left-and-right direction of the assembly device. The first positioning mechanism 3 includes two positioning rods 31 arranged at intervals along the first direction and a first driving assembly 32. The positioning rods 31 extend along the second direction. The first driving assembly 32 is used to drive the upper positioning rod 31 among the two positioning rods 31 to move in the direction of approaching or separating, so that the two positioning rods 31 can clamp and position the wing plate a in the first direction.

[0029] In this embodiment, the H-shaped steel with two wing plates a of the same width is defined as the H-shaped steel in the standard state, and the H-shaped steel with two wing plates a of different widths is defined as the H-shaped steel in the non-standard state.

[0030] When assembling the H-shaped steel in the standard state, place the two wing plates a vertically between the two positioning rods 31. Control the positioning rods 31 to move downward by the first driving assembly 32 until the wing plates a are clamped, and the positioning of the two wing plates a is completed. The operation is quick and convenient.

[0031] When assembling the H-shaped steel in the non-standard state, since the widths of the two wing plates a are different, and the positioning rods 31 can only position the wing plate a with a larger width and cannot clamp and position the wing plate a with a smaller width. On this basis, a third positioning mechanism 5 that can move along the second direction is movably installed on the two positioning rods 31, and the third positioning mechanism 5 extends from the positioning rods 31 towards the wing plate a along the first direction, that is, the third positioning mechanism 5 has a certain thickness in the second direction. During assembly, first move the third positioning mechanism 5 to the position corresponding to the wing plate a with a smaller width, place the wing plate a with a smaller width vertically on the third positioning mechanism 5, and then control the first driving assembly 32 to move the positioning rods 31 downward so that the two third positioning mechanisms 5 are in close contact with the wing plate a with a smaller width respectively, thereby clamping the wing plate a with a smaller width. Correspondingly, when assembling the H-shaped steel in the standard state, just remove the third positioning mechanism 5 so that the third positioning mechanism 5 will not interfere with the assembly of the H-shaped steel in the standard state. The assembly device in the present utility model can be used for both the assembly of the H-shaped steel in the standard state and the assembly of the H-shaped steel in the non-standard state, improving the applicable range of the assembly device and having a relatively simple structure.

[0032] At the same time, since the web b is between the two wing plates a and is perpendicular to the two wing plates a during assembly, to meet different processing requirements, the width of the web b may change. However, since the third positioning mechanism 5 can move along the second direction, when assembling the H-shaped steel in the non-standard state, it can adapt to the web b with different widths.

[0033] It should be noted that when assembling the H-beam in a non-standard state, in order to ensure that the third positioning mechanism 5 can clamp the wing plate a with a smaller width in the first direction, the thickness of the third positioning mechanism 5 located between the two positioning rods 31 in the first direction should be slightly greater than or equal to the spacing distance between the positioning rod 31 and the wing plate a with a smaller width in the first direction.

[0034] In this embodiment, at least two first positioning mechanisms 3 are provided, which respectively act on both ends of the wing plate a in the length direction, that is, the first positioning mechanism 3 can fix the wing plate a from both ends, so as to ensure that the wing plate a can maintain an accurate position during assembly.

[0035] Furthermore, to meet the assembly requirements of more H-beams, the third positioning mechanism 5 is detachably connected to the positioning rod 31. When assembling the H-beam in a non-standard state, when the width of the wing plate a changes, only the third positioning mechanism 5 with different sizes needs to be replaced.

[0036] Specifically, the third positioning mechanism 5 includes two symmetrically arranged positioning members 51 that are engaged with the positioning rod 31. The shape of the inner surface of the positioning member 51 matches the shape of the outer surface of the positioning rod 31, so that the positioning member 51 can fit on the positioning rod 31. For example, when the positioning rod 31 is cylindrical, the positioning member 51 is two semi-circular rings, and the inner arc surface of the semi-circular ring matches the outer surface of the positioning rod. At the same time, a plurality of corresponding connection hole plates 52 are respectively provided on the sides of the two positioning members 51, and a fastening assembly 53 is provided on the paired two connection hole plates 52. The fastening assembly 53 is used to adjust the tightness of the contact between the positioning member 51 and the positioning rod 31. When the contact between the positioning member 51 and the positioning rod 31 is relatively tight, there is a large static friction force between the positioning member 51 and the positioning rod 31, and the positioning member 51 can be clamped on the positioning rod 31, ensuring the stability of the connection between the positioning member 51 and the positioning rod 31. When the contact between the positioning member 51 and the positioning rod 31 is relatively loose, the operator can control the positioning member 51 to move along the second direction on the positioning rod 31 to change its position, so as to meet the position requirements of the positioning member 51 when assembling the H-beam in a non-standard state.

[0037] In this embodiment, the first driving assembly 32 can be a telescopic hydraulic cylinder or a telescopic pneumatic cylinder, and its movable end is connected to the positioning rod 31. The first driving assembly 32 can not only accurately control the movement of the positioning rod 31, but also provide stable and sufficient pressure to the positioning rod 31 in the first direction, so as to ensure the structural stability of the wing plate a during assembly.

[0038] Preferably, the fastening assembly 53 is composed of a bolt 531 and two nuts 532. The bolt 531 passes through the corresponding two connecting hole plates 52, and the two nuts 532 are screwed onto the bolt 531. By adjusting the nuts 532, the tightness between the positioning member 51 and the positioning rod 31 can be adjusted, which is convenient to operate. At the same time, the cooperation of one bolt 531 and two nuts 532 can also realize the disassembly of the third positioning mechanism 5.

[0039] When assembling non-standard H-beams, when the width of the wing plate a with a smaller width changes, the nuts 532 can be disassembled to replace the positioning members 51 with different thicknesses, so that the device can meet the assembly requirements of wing plates a with different width dimensions.

[0040] Furthermore, a sliding connector 6 is provided between the first driving assembly 32 and the positioning rod 31. The sliding connector 6 is slidably connected to the frame 1 in the second direction, and the positioning rod 31 is provided on the connector. When the positioning rod 31 moves up and down under the control of the first driving assembly 32, the sliding connector 6 can provide a guiding function for the movement of the positioning rod 31 to ensure that the positioning rod 31 always moves in the first direction, thereby realizing the accurate positioning of the wing plate a.

[0041] The second positioning mechanism 4 includes an upper positioning assembly 41 and a lower positioning assembly 42. The lower positioning assembly 42 is connected to the bottom of the mounting seat 2 and is used to support the web b. The upper positioning assembly 41 is connected to the top of the mounting seat 2 and is used to position the web b on the lower positioning assembly 42 from above the web b, thereby fixing the web b. Specifically, referring to Figure 4 , the upper positioning assembly 41 includes an upper positioning portion 412 and a second driving assembly 411 for driving the upper positioning portion 412 to move in a direction close to or away from the web b. The lower positioning assembly 42 includes a lower positioning portion 421 and a third driving assembly 422 for driving the lower positioning portion 421 to move in a direction close to or away from the web b.

[0042] Among them, during the assembly process of the web b, the lower positioning assembly 42 can not only support the web b, but also drive the web b to move upward by the up and down movement of a plurality of lower positioning portions 421 to transfer the web b to a specified assembly position, which helps to improve the assembly efficiency of the web b.

[0043] Furthermore, the number of both the lower positioning assembly 42 and the upper positioning assembly 41 is multiple, and the multiple upper positioning assemblies 41 are arranged at intervals along the length direction of the web b, and the multiple lower positioning assemblies 42 are arranged at intervals along the length direction of the web b, so that the web b can be supported and positioned throughout the entire length range, avoiding local offset and distortion.

[0044] In this embodiment, the second driving assembly 411 and the third driving assembly 422 can be telescopic hydraulic cylinders or telescopic pneumatic cylinders, etc., and the positioning portion is provided at the movable end of the telescopic hydraulic cylinder. In this embodiment, the upper positioning portion 412 and the lower positioning portion 421 are provided as rollers, and the rollers are rotatably connected to both the second driving assembly 411 and the third driving assembly 422. The web b can be accurately positioned by contacting the web b with the rollers to clamp the web b.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
