[0042] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0043] like Figure 1 and Figure 2 As shown, according to the first aspect of an embodiment of the present disclosure, a pipeline welding auxiliary tooling is proposed, including: a first clamping part 120; a second clamping part 130, the second clamping part 130 is connected to the first clamping part 120, a clamping groove 1001 is formed between the first clamping part 120 and the second clamping part 130, the clamping groove 1001 is conductive along the first direction, and the clamping groove 1001 is used to clamp the main pipeline 10; wherein, along the first direction, a positioning groove 1002 is formed at one end of the first clamping part 120 or the second clamping part 130, the positioning groove 1002 is conductive along the second direction, and the positioning groove 1002 is used to clamp the branch pipeline 20, and the first direction intersects with the second direction.

[0044] According to the present disclosure, an embodiment of the present invention proposes a pipeline welding auxiliary tool, including a first clamping portion 120 and a second clamping portion 130, wherein the first clamping portion 120 and the second clamping portion 130 are connected, and a clamping groove 1001 is formed between the first clamping portion 120 and the second clamping portion 130, and the clamping groove 1001 is used to clamp the main pipeline 10, and the clamping groove 1001 is conductive along the first direction, that is, the main pipeline 10 is clamped in the clamping groove 1001 along the first direction; a positioning groove 1002 is formed at one end of the first clamping portion 120 or the second clamping portion 130, that is, the positioning groove 1002 is located at one end of the clamping groove 1001 in the first direction, and the positioning groove 1002 is conductive along the second direction, and the second direction intersects with the first direction, so that when the branch pipeline 20 is clamped in the positioning groove 1002, the branch pipeline 20 can move along the second direction until it abuts against the main pipeline 10; in actual application, the main pipeline 10 can be clamped on the clamping groove 1001 first, so that the positioning groove 1002 can correspond to the processing hole of the main pipeline 10, that is, the center of the arc notch of the positioning groove 1002 is aligned with the center of the processing hole on the main pipeline 10, and then the branch pipeline 20 is inserted into the positioning groove 1002, and the position of the branch pipeline 20 is adjusted along the second direction, so that the branch pipeline 20 can abut against the main pipeline 10, so that the branch pipeline 20 and the main pipeline 10 can be aligned, and then the branch pipeline 20 and the main pipeline 10 are welded by welding. Based on the above-mentioned pipeline welding auxiliary tooling, the alignment degree of the processing hole of the branch pipeline 20 and the main pipeline 10 can be improved, which is beneficial to ensure the pipeline flow diameter after welding, and at the same time, it can also improve the welding efficiency of the branch pipeline 20.

[0045] It can be understood that the clamping groove 1001 can be opened in the first clamping part 120, the clamping groove 1001 can also be opened in the second clamping part 130, or a first groove 1201 can be opened on the first clamping part 120 and a second groove can be opened on the second clamping part 130, and the first groove 1201 and the second groove together constitute the clamping groove 1001.

[0046] It can be understood that the size of the positioning groove 1002 can be set according to the thickness of the branch pipeline 20 to ensure that when the branch pipeline 20 is snapped into the positioning groove 1002, the positioning groove 1002 can play a sufficient limiting role on the branch pipeline 20, thereby reducing the risk of the branch pipeline 20 sliding relative to the main pipeline 10 during welding.

[0047] It is understandable that when the branch pipe 20 is clamped in the positioning groove 1002, along the first direction, at least part of the branch pipe 20 is located outside the positioning groove 1002, so that the operator can weld the branch pipe 20 from the side away from the first clamping portion.

[0048] It should be noted that in the traditional technology, during the process of combining the main pipeline 10 and the branch pipeline 20 by welding, usually one operator holds the branch pipeline 20, and another operator performs the welding. To ensure the welding effect, the operator holding the branch pipeline 20 needs to spend a great deal of energy to keep the branch pipeline 20 stable. However, affected by the light arc generated during welding, it is still difficult for the operator holding the branch pipeline 20 to maintain the stable positioning of the branch pipeline 20, which is likely to cause the misalignment of the processing holes of the branch pipeline 20 and the main pipeline 10, resulting in a reduction in the flow diameter of the pipeline and an inability to meet the requirements for the pipeline flow diameter. Compared with the traditional technology, based on the foregoing settings, the pipeline welding auxiliary tooling proposed in the embodiments of the present disclosure enables the operator to abut the branch pipeline against the positioning groove with a relatively small force, align the outer shape of the branch pipeline with the circular arc notch of the positioning groove, thereby realizing the positioning of the branch pipeline 20, improving the alignment degree between the center of the branch pipeline 20 and the center of the processing hole of the main pipeline 10, facilitating ensuring the flow diameter of the pipeline after welding, and at the same time improving the welding efficiency of the branch pipeline 20.

[0049] Exemplarily, a first groove 1201 is formed in the first clamping portion 120, and a second groove is formed in the second clamping portion 130. The first groove 1201 and the second groove together form a clamping groove 1001.

[0050] In some examples, as Figure 1 and Figure 2 shown, it further includes: a rotating shaft 110 arranged along the first direction, the rotating shaft 110 passing through the first clamping portion 120 and the second clamping portion 130 to hinge the first clamping portion 120 and the second clamping portion 130;

[0051] an adjusting portion 140 detachably passing through the first clamping portion 120 and the second clamping portion 130, the adjusting portion 140 being located on the side of the clamping groove 1001 away from the rotating shaft 110, and the adjusting portion 140 being used to adjust the distance between the first clamping portion 120 and the second clamping portion 130.

[0052] In the above technical solution, the tooling also includes a rotating shaft 110 and an adjusting portion 140, wherein the first clamping portion 120 and the second clamping portion 130 are hingedly connected through the rotating shaft 110, and the adjusting portion 140 is detachably provided on the side of the clamping groove 1001 away from the rotating shaft 110; in practical applications, the first clamping portion 120 and the second clamping portion 130 can be rotated in a direction away from each other, so that the main line 10 can be moved between the first clamping portion 120 and the second clamping portion 130, so that the main line 10 is located in the clamping groove 1001, and then the distance between the first clamping portion 120 and the second clamping portion 130 is adjusted by the adjusting portion 140, so that the first The clamping portion 120 and the second clamping portion 130 are close to each other, so that the first clamping portion 120 and the second clamping portion 130 can clamp the main line 10, that is, clamp the main line 10 on the clamping groove 1001; since the clamping groove 1001 is arranged along the first direction, the clamping groove 1001 is also conductive along the first direction, so that before the first clamping portion 120 and the second clamping portion 130 clamp the main line 10, the relative positions of the processing hole of the main line 10 and the positioning groove 1002 can be adjusted along the first direction, so that the processing hole of the main line 10 can correspond to the positioning groove 1002, and the center of the processing hole of the main line 10 is aligned with the center of the arc notch of the positioning groove.

[0053] It can be understood that when the first clamping portion 120 and the second clamping portion 130 rotate in a direction away from each other, the first groove 1201 rotates in a direction away from the second groove, and the clamping groove 1001 opens; when the first clamping portion 120 and the second clamping portion 130 rotate in a direction approaching each other, the first groove 1201 rotates in a direction close to the second groove, and the clamping groove 1001 closes; when the first clamping portion 120 and the second clamping portion 130 clamp the main line 10, a portion of the main line 10 is located in the first groove 1201, and a portion of the main line 10 is located in the second groove, thereby better limiting the main line 10.

[0054] It can be understood that the above arrangement can also make the first groove 1201 and the second groove suitable for main pipes 10 with various apertures.

[0055] Exemplarily, the first groove 1201 and the second groove are both semi-cylindrical in shape, so as to better fit the main pipeline 10 , which is beneficial to improving the limiting effect of the first groove 1201 and the second groove on the main pipeline 10 .

[0056] In some examples, such as Figure 1 and Figure 2 As shown, along the first direction, at least one end of the first clamping portion 120 is formed with a positioning groove 1002 ; and along the first direction, at least one end of the second clamping portion 130 is formed with a positioning groove 1002 .

[0057] In the above technical solution, positioning grooves 1002 are provided on both the first clamping portion 120 and the second clamping portion 130. When using the positioning groove 1002 on the first clamping portion 120 for auxiliary positioning, the positioning groove 1002 at one end of the first clamping portion 120 can be aligned with the processing hole of the main pipeline 10, and then the second clamping portion 130 is adjusted, which is beneficial to ensuring the alignment degree between the positioning groove 1002 and the processing hole of the main pipeline 10 during the adjustment process; when using the positioning groove 1002 on the second clamping portion 130 for auxiliary positioning, the positioning groove 1002 at one end of the second clamping portion 130 can be aligned with the processing hole of the main pipeline 10, and then the first clamping portion 120 is adjusted, which is beneficial to ensuring the alignment degree between the positioning groove 1002 and the processing hole of the main pipeline 10 during the adjustment process.

[0058] In the above technical solution, the positioning grooves 1002 are provided on both the first clamping portion 120 and the second clamping portion 130 at the same time, which is beneficial to adapting to more working conditions and also facilitating the operator to obtain a better welding position.

[0059] In some examples, such as Figure 1 and Figure 2 as shown, the inner groove wall of the positioning groove 1002 is used to fit the outer pipe wall of the branch pipeline 20, and different positioning grooves 1002 have different shapes.

[0060] In the above technical solution, the inner groove wall of the positioning groove 1002 is selected according to the size of the outer pipe wall of the branch pipeline 20, so that the outer pipe wall of the branch pipeline 20 can be adapted to the inner groove wall of the positioning groove 1002. Thus, during the auxiliary positioning process, the operator only needs a relatively small force to maintain the alignment of the branch pipeline 20 with the processing hole of the main pipeline 10; at the same time, different positioning grooves 1002 can be set with different shapes to facilitate the application to various branch pipelines 20 with different shapes.

[0061] It can be understood that if the branch pipeline 20 is a square pipe, the shape of the positioning groove 1002 can be a rectangular groove; if the branch pipeline 20 is a round pipe, the positioning groove 1002 can be a semi-cylindrical groove. The specific shape and size of the positioning groove 1002 can be selected according to the shape of the branch pipeline 20, and the shape of the positioning groove 1002 will not be elaborated one by one here.

[0062] In some examples, such as Figure 1 and Figure 2 as shown, the first clamping portion 120 includes:

[0063] A clamping member, and part of the clamping groove 1001 is formed on the clamping member;

[0064] A limiting member, which is arranged on the clamping member, at least two limiting members are arranged at intervals along the first direction, and the rotating shaft 110 passes through the limiting member;

[0065] Among them, at least part of the second clamping portion 130 is located between two adjacent limiting members.

[0066] In the above technical solution, the first clamping portion 120 includes a clamping member and a limiting member. The clamping member and the limiting member are connected. The number of limiting members is at least two. The limiting members are sleeved on the rotating shaft 110. Along the first direction, the two limiting members are arranged at intervals, and at least part of the second clamping portion 130 is located between two adjacent limiting members. Thus, the limiting members can prevent the second clamping portion 130 from having a large relative movement along the first direction, which is beneficial to ensuring the relative position relationship between the first clamping portion 120 and the second clamping portion 130, and is beneficial to ensuring the clamping ability of the first clamping portion 120 and the second clamping portion 130.

[0067] It can be understood that the clamping member and the limiting member can be of an integral structure.

[0068] It can be understood that part of the clamping groove 1001 formed on the clamping member is the first groove 1201.

[0069] In some examples, the adjusting portion 140 includes:

[0070] A fastening bolt 141, which passes through the first clamping portion 120 and the second clamping portion 130;

[0071] A fastening nut 142, which is threadedly connected to the fastening bolt 141.

[0072] In the above technical solution, the adjusting member includes a fastening bolt 141 and a fastening nut 142; holes are provided on the first clamping portion 120 and the second clamping portion 130, and the fastening bolt 141 passes through these holes. At the same time, through the threaded connection relationship between the fastening bolt 141 and the fastening nut 142, the distance between the first clamping portion 120 and the second clamping portion 130 is adjusted. The operation is simple and convenient, the clamping force transmission is stable, and the first clamping portion 120 and the second clamping portion 130 can stably clamp the main pipeline 10.

[0073] In some examples, it further includes: a limit pin. The rotating shaft 110 uses a pin shaft, and the limit pin is arranged on the pin shaft.

[0074] In the above technical solution, the pipeline welding auxiliary tooling further includes a limit pin. The rotating shaft 110 uses a pin shaft, and the limit pin arranged on the pin shaft can play a role in limiting the first clamping portion 120 and the second clamping portion 130, and can prevent the first clamping portion 120 and the second clamping portion 130 from slipping off the rotating shaft 110, which is beneficial to improving the stability of the device.

[0075] In some examples, as Figure 1 and Figure 2 shown, the first direction is perpendicular to the second direction.

[0076] In the above technical solution, the first direction is perpendicular to the second direction, that is, the conduction direction of the positioning groove 1002 is perpendicular to the conduction direction of the clamping groove 1001, which is more conducive to the auxiliary positioning of the vertical connection between the main pipeline 10 and the branch pipeline 20.

[0077] It can be understood that the vertical connection between the main pipeline 10 and the branch pipeline 20 is a connection method widely used in the field. With the above setting method, the utilization rate of the pipeline welding auxiliary tooling can be improved.

[0078] In some examples, it further includes:

[0079] A positioning pipe, which is used to be inserted into the main pipeline 10 and is used to abut against the positioning groove 1002.

[0080] In the above technical solution, the pipeline welding auxiliary tooling further includes a positioning pipe, which is used to assist in the positioning between the positioning groove 1002 and the processing hole of the main pipeline 10, so that the center of the arc notch of the positioning groove 1002 is aligned with the center of the processing hole of the main pipeline; in actual application, the positioning pipe can be inserted into the processing hole of the main pipeline 10, and then the positioning groove 1002 is abutted against the positioning pipe, so as to achieve the alignment between the positioning groove 1002 and the processing hole.

[0081] Preferably, the positioning pipe has a stepped structure, and each positioning pipe has at least two steps, and each step has a different aperture; taking two steps as an example, during use, the section with a smaller aperture of the positioning pipe can be inserted into the processing hole of the main pipeline 10, and then the positioning groove 1002 is abutted against the section with a larger aperture of the positioning pipe. When fixing the relative positions among the first clamping portion 120, the second clamping portion 130 and the main pipeline 10, it can be ensured that after the positioning pipe is removed, a margin for the pipe wall of the branch pipeline 20 is reserved between the groove wall of the positioning groove 1002 and the hole wall of the processing hole of the main pipeline 10, so as to ensure the maximum flow rate between the branch pipeline 20 and the processing hole of the main pipeline 10.

[0082] It can be understood that multiple stepped structures of the positioning pipe can also be set to facilitate adaptation to various different aperture situations.
