In the above-mentioned large-scale frame structure, it is generally composed of a top cover, a base, and various columns. The columns include corner columns, single columns, and composite columns. The structures must be welded to achieve product size and error. In the prior art, the base is first placed on a welding platform that has been adjusted to a horizontal level, and then the angle columns, composite columns, and multiple single columns are adjusted in position and verticality with a tape measure and a positioning angle ruler according to the requirements of the drawings, and then the various columns are welded to the base; then the top cover is spot welded to the positioned columns; finally, the entire spliced ​​frame structure is welded from the outside to the inside. In the above-mentioned welding process, various columns are temporarily fixed by spot welding, and it is difficult to ensure the standard position of each column, which in turn affects the dimensional error requirements of the entire large frame. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an auxiliary device for welding a large frame, including a column connection and fixing unit for forming a column module unit with at least two columns. By connecting and fixing the column to form a column module unit with at least two columns, the number of columns that need to control the standard position is reduced during splicing and welding, that is, the difficult-to-control standard position caused by temporary spot welding and fixing of a single column is reduced, so that the dimensional error requirements during the assembly and welding of a large frame are better adjusted and controlled, and at the same time, the column positioning is more convenient and the operation is simpler.

[0004] In one embodiment, the column connection and fixing unit is a strip-shaped body with a connection hole, and the connection hole is matched with the fixing hole set on the column. By setting the column connection and fixing unit as a strip-shaped body, the connection hole and the fixing hole are respectively set on the strip-shaped body and the column according to the standard position, so that when the two are connected and fixed, the connected multiple columns form a standard column module unit, reducing the position deviation caused by a single column, improving product quality and production progress; and setting the hole structure and the bolt fixing structure, the structure is simple and easy to operate.

[0005] In one embodiment, the strip-shaped body is a square tube, a rectangular tube or a C-shaped steel.

[0006] In one embodiment, the strip-shaped body comprises at least 2. Through this arrangement, the formed column module unit can be made more stable and easier to control.

[0007] In one embodiment, telescopic units are arranged between the strip-shaped bodies. By arranging telescopic units between the strip-shaped bodies, the contraction and expansion of the multiple strip-shaped bodies can be realized, which is convenient for operation and better for positioning.

[0008] In one embodiment, the strip-shaped body is provided with a slot for clamping at least a part of the pillars. By providing the slot, when the strip-shaped body is connected and fixed with the pillars, the positioning requirement can be further better achieved.

[0009] In one embodiment, a module connection fixing unit is also included to connect the column module units. By setting the module connection fixing unit, the connection positioning between the column module units can be achieved, and the dimensional error requirements of the final product can be further achieved. It is more convenient to reduce the time of adjusting the positioning during assembly and welding, thereby improving efficiency.

[0010] In one embodiment, the module connection fixing unit is a part of the column connection fixing unit. The module connection fixing unit is designed to be at least a part of the column connection fixing unit, or even the same as the column connection fixing unit, so that the two can be used equally, so that the two can be mixed without distinction, reduce the occurrence of connection positioning errors, and improve production efficiency while improving positioning requirements.

[0011] In one embodiment, a reinforcing connection and fixing unit is further included between the column and the base and / or the top cover. By setting the reinforcing connection and fixing unit, the stability and firmness of the overall product are achieved, and the error requirements of the overall product are guaranteed.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Example 1

[0027] like Figure 1-Figure 5 As shown, this embodiment discloses an auxiliary device for welding a large frame. In this embodiment, taking a large rectangular frame as an example, it includes a top cover 11, a base 12 and various columns. The columns include corner columns 8, single columns 9 and composite columns 10. As for the structure of the composite column 10, there is no specific restriction. For example, it is formed by multiple single columns, or some single columns are combined with other structures.

[0028] The auxiliary device includes a column connection and fixing unit that forms a column module unit with at least two columns. In this embodiment, the column connection and fixing unit is a strip body 1 with a connection hole 2. The structure of the strip body 1 is not specifically limited, such as a square tube, a rectangular tube or a C-shaped steel structure, preferably a C-shaped steel structure. The shape of the connection hole 2 is not specifically limited, preferably a circular hole, which matches the fixing hole set on the column. The fixing hole is preferably a threaded hole. When in use, the column is fixedly connected to the strip body 1 by passing the fixing bolt through the connection hole 2 and screwing it into the fixing hole. The number or quantity of the strip body 1 is not specifically limited, and is determined according to the length of the modularized column. In this embodiment, the number or quantity of the strip body 1 is 3. Of course, the position of the connection hole 2 on the strip body 1 is set according to the standard position of the column, so that after the connection hole 2 is matched with the fixing hole, the position of the column is basically located at the standard position. Of course, the length of the strip body 1 is designed according to the distance between the middle of the column. The strip body 1 connects and fixes the columns to form several column module units. Specifically, Figure 1-3 , forming three column module units, wherein the first column module unit is composed of three strip bodies 1, two corner columns 8 and three single columns, such as Figure 1 As shown; the second column module unit is composed of three strip bodies 1 and three single columns, as shown Figure 2 As shown; the third column module unit is composed of 6 strip bodies 1, 2 corner columns 9, 1 composite column and 4 single columns, as shown Figure 3 shown.

[0029] The first column module unit, the second column module unit and the third module unit form a frame module through a module connection and fixing unit.

The structure of the module connection unit is not specifically limited. Preferably, it is consistent with the structure of the column connection and fixing unit, or is a part of the column connection and fixing unit, or is an extension of the column connection and fixing unit. In this embodiment, the module connection unit is the structure of the above-mentioned strip body 1, and its length can be selected according to the specific situation. Of course, a structure matching the strip body structure is formed on the column. Of course, the module connection and fixing unit only fixes a part of the column module unit, and the rest can be used as a separate module to cooperate with the base 12 and the top cover 11, such as Figure 4 As shown, the first column module unit and the third column module unit form a frame module through a module connection fixing unit, while the second column module unit is set up separately.

[0030] like Figure 5 As shown, when Figure 4 The structure shown is arranged between the base 12 and the top cover 11, and a reinforced connection and fixing unit 7 is formed between the column and the base 12, and between the column and the top cover 11. The structure is not specifically limited. In the present embodiment, the reinforced connection and fixing unit 7 is a reinforcing rib structure. Specifically, a triangular structure is formed between the three, which further increases the strength and ensures the size requirements.

When the telescopic unit 4 is extended or shortened, the strip bodies 1 are stretched or contracted, which is convenient for use. Specifically, four parallel telescopic units 4 are installed between three strip bodies 1. The structure of the telescopic unit 4 is not specifically limited, such as a slide rail assembly, a telescopic rod or a telescopic frame. In this embodiment, Figure 7 As shown, the telescopic unit 4 is a diamond-shaped retractable frame.

[0033] Example 3

[0034] This embodiment discloses an auxiliary device for welding large frames, which is a variation of Embodiment 1 or Embodiment 2, specifically as follows: a slot 5 is formed on the strip body 1, and the slot 5 at least clamps the main part of the column, so that the connection and fixation of the column is more stable, and the dimensional stability is better guaranteed, and the dimensional error requirements are met.

[0035] The use process of the utility model is as follows:

[0036] First, the assembly of the column module unit, such as Figure 1-Figure 3 As shown, the first column module unit, the second column module unit and the third column module unit are formed according to the diagram; secondly, the base 12 is placed on the platform, the position is adjusted to leave a position for the tightener, and then the first column module unit and the third module column unit are inserted into the corresponding positions of the base, and the above two module column units are connected and fixed by the module connection and fixing unit (strip body and bolts), and then the second module column unit is hoisted by a tool (crane or crane) to be inserted into the corresponding position of the base, and then the top cover 11 is hoisted by a tool (crane or crane) to make it cooperate with the first column module unit, the second column module unit and the third column module unit; again, by measuring the size and using the locker to make the tolerance of each size meet the requirements; again, the strengthening connection and fixing unit is spot welded and reinforced; again, the connection is welded according to the welding process; finally, the strip body and the strengthening connection and fixing unit are removed.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods.
