[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0034] like Figure 1-Figure 7 As shown, according to an embodiment of the first aspect of the utility model, a welding auxiliary tool 100 is used for welding between a connecting plate 300 and a steel section 200. The steel section 200 may be an H-shaped steel, the steel section 200 may be an I-shaped steel, or the steel section 200 may be a channel steel. The connecting plate 300 is located at one end of the steel section 200, and the two are welded together.

[0035] In actual application, the connection plate 300 is provided with a plurality of connection holes, and each connection hole has a relative position with the steel 200, that is, there is a relative position between the connection plate 300 and the steel 200. In the related art, welding operators rely on their experience to locate the position to be connected and then weld. However, different welding operators have deviations in their judgment of the welding position, which leads to the misalignment of the bolt penetration holes (or connection holes) between adjacent arch frames and the misalignment of the force axis of the arch frames.

[0036] Based on this, the present embodiment provides a welding auxiliary tooling 100, which can be used to weld the connecting plate 300 to one end of the steel section 200, to ensure that the relative position between the connecting hole on the connecting plate 300 and the steel section 200 is accurate, that is, to limit the degree of freedom of the connecting plate 300, and the relative setting between the connecting plate 300 and the steel section 200 meets the design requirements, thereby avoiding the welding workers relying on experience to locate the required connection position.

[0037] The welding auxiliary tool 100 includes a support plate 10, on which a clamping portion, a first positioning portion and a second positioning portion are provided. The clamping portion is used to clamp to one end of any one of an H-shaped steel, an I-shaped steel or a channel steel. The first positioning portion is used to limit the degree of freedom of the connecting plate 300 in a first direction C1, and the second positioning portion is used to limit the degree of freedom of the connecting plate 300 in a second direction C2.

[0038] The first direction C1 is the length direction of the cross section of any one of the H-shaped steel, I-shaped steel or channel steel, and the second direction C2 is the width direction of the cross section of any one of the H-shaped steel, I-shaped steel or channel steel.

[0039] Take steel 200 as H-beam as an example: Figure 2 As shown, a clamping portion is provided on the support plate 10, and the clamping portion can be a substantially C-shaped notch 11. The notch 11 can be clamped with the H-shaped steel, such as Figure 1 and Figure 5 As shown, the notch 11 includes a first rectangular hollow area 111 and two second rectangular hollow areas 112, and one second rectangular hollow area 112, the first rectangular hollow area 111 and another second rectangular hollow area 112 are arranged along a first direction C1 to form a C shape. The first direction C1 is the length direction of the cross section of the H-shaped steel.

[0040] The size of the second rectangular hollow area 112 in the first direction C1 is slightly larger than the thickness of the flange plate of the H-beam. In this way, the welding auxiliary tool 100 can be placed on the H-beam. Based on the fact that the size of the second rectangular hollow area 112 in the first direction C1 is slightly larger than the thickness of the flange plate of the H-beam, the degree of freedom of the welding auxiliary tool 100 in the first direction C1 is limited and constrained, which helps the welding auxiliary tool 100 to be stably placed on the H-beam. At the same time, the welding auxiliary tool 100 can be adapted to various specifications of H-beams.

[0041] In addition, the end surface 16 of the support plate 10 in contact with the first rectangular hollow area 111 abuts against the H-shaped steel, which can limit the freedom of the welding auxiliary tooling 100 in the second direction C2, and the second direction C2 is the width direction of the cross section of the H-shaped steel.

[0042] Of course, it can be understood that the welding auxiliary tooling 100 can be adapted to channel steel, and a C-shaped notch 11 is provided on the support plate 10 of the welding auxiliary tooling 100. The welding auxiliary tooling 100 can be clamped on the channel steel, and the size ratio of the second rectangular hollow area 112 in the first direction C1 is greater than the thickness of the leg plate of the channel steel, and the degree of freedom of the welding auxiliary tooling 100 in the first direction C1 is limited and constrained; the end surface 16 where the support plate 10 and the first rectangular hollow area 111 meet is against the waist plate of the channel steel 200. In this way, the degree of freedom of the welding auxiliary tooling 100 in the second direction C2 can be limited, thereby facilitating the welding auxiliary tooling 100 to be stably placed on the channel steel.

[0043] In some embodiments of the present invention, a mounting hole 15 is provided on the support plate 10, and the screw rod 12 is installed in the mounting hole 15. The screw rod 12 is a first positioning portion and a second positioning portion.

[0044] In a specific embodiment, Figure 3 and Figure 4As shown, two mounting holes 15 are provided on the support plate 10, wherein the relative distance between the two mounting holes 15 and the relative distance between the two mounting holes 15 and the end faces 16 where the support plate 10 and the first rectangular hollow area 111 meet are all set by technicians in this field according to actual conditions.

[0045] The two screw rods 12 are respectively installed on the two mounting holes 15. The two connecting holes on the connecting plate 300 are respectively arranged corresponding to the two screw rods 12, so that the connecting plate 300 can be installed on the welding auxiliary tooling 100 through the screw rods 12, and the connecting plate 300 fits with one end of the H-shaped steel, and then the welding operator can perform welding. Among them, since the relative distance between the two mounting holes 15 and the relative distance between the mounting holes 15 and the end face 16 where the support plate 10 and the first rectangular hollow area 111 are connected are all designed dimensions. Therefore, the screw rod 12 installed in the mounting hole 15 has a positioning function in the first direction C1 and the second direction C2, so that the relative position between the connecting plate 300 and the H-shaped steel can be accurately positioned, so that the relative setting between the connecting plate 300 and the steel 200 meets the design requirements, avoiding the welding operator to rely on experience to position the required connection position.

[0046] Alternatively, if Figure 6 As shown, the mounting hole 15 is a long hole. The length of the long hole extends along the second direction C2. Therefore, the nut on the screw rod 12 can be loosened so that the screw rod 12 can move in the second direction C2, and then the relative distance between the mounting hole 15 and the end surface 16 where the support plate 10 and the first rectangular hollow area 111 meet can be adjusted.

[0047] Similarly, if Figure 7 As shown, the mounting hole 15 is an elongated hole. The length of the elongated hole extends along the first direction C1. Therefore, the nut on the screw rod 12 can be loosened so that the screw rod 12 can move in the first direction C1, and then the relative distance between the two mounting holes 15 can be adjusted.

[0048] Such configuration enables the welding auxiliary tool 100 to be adapted to different types of connecting plates 300 .

[0049] Optionally, a positioning sleeve 40 is sleeved on the screw rod 12 .

[0050] In practical applications, the connection holes on the connection plate 300 may have different diameters. In order to make the welding auxiliary tool 100 adaptable to connection holes of different diameters on the connection plate 300, a positioning sleeve 40 may be set on the screw rod 12, such as Figure 3 The diameter of the positioning sleeve 40 can match the connecting hole on the connecting plate 300 .

[0051] It should be noted that, in addition to the first positioning portion and the second positioning portion being configured as the above-mentioned screw 12, other structures may also be used, which are not listed one by one in this embodiment.

[0052] In some embodiments of the present invention, the welding auxiliary tooling 100 further includes a balance plate 20. The balance plate 20 is connected to the surface of the support plate 10 so that the balance plate 20 abuts against the web of the H-shaped steel or I-shaped steel, or the balance plate 20 abuts against the waist of the channel steel 200.

[0053] In a specific embodiment, Figure 1 As shown, the balance plate 20 is connected to the surface of the support plate 10 facing away from the connecting plate 300, and the balance plate 20 is abutted against the web of the H-shaped steel, which can further enable the welding auxiliary tooling 100 to be stably set on the H-shaped steel, thereby avoiding accidental shaking of the welding auxiliary tooling 100, which in turn affects the relative setting between the connecting plate 300 and the steel 200.

[0054] In addition, if Figure 1 As shown, an auxiliary balancing plate 30 is further connected to the surface of the support plate 10 facing away from the connecting plate 300, and the auxiliary balancing plate 30 abuts against the outer surface of the flange plate of the H-beam. The abutment between the auxiliary balancing plate 30 and the flange plate can limit the degree of freedom of the welding auxiliary tooling 100 in the first direction C1, and at the same time, it helps the welding auxiliary tooling 100 to be stably arranged on the H-beam.

[0055] In some embodiments of the present invention, Figure 1 As shown, the support plate 10 is provided with a handle hole 14 to help welding workers to take it.

[0056] According to the second aspect of the present invention, a welding auxiliary tooling assembly 100 includes a connecting plate 300, a steel section 200, and the welding auxiliary tooling 100 in the first aspect. The steel section 200 can be any one of an H-shaped steel, an I-shaped steel, or a channel steel. The connecting plate 300 is welded to one end of the steel section 200. In order to ensure the relative position between the connecting plate 300 and the steel section 200, the welding auxiliary tooling 100 can be used to weld the two. In this way, the relative setting between the connecting plate 300 and the steel section 200 meets the design requirements, avoiding the welding operator relying on experience to locate the required connection position.
