In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there can be an element in the middle. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there can be an element in the middle. When an element is referred to as "set on" another element, it can be set on the other element or there can be an element in the middle.

[0040] Reference Figure 1One embodiment of the present application provides a welding test jig 100, comprising an upright column 10, a horizontal column 20, a first clamping member 30, a second clamping member 40, and an assembly aid 50. The horizontal column 20 is fixed to the top of the upright column 10. For example, the various structural components of the welding test jig 100 may be metal, and the structural components may be fixedly connected by welding. The upright column 10 may be fixed to the ground or other mounting base.

[0041] The first clamping member 30 includes two first clamping portions 31 disposed opposite each other, with the gap between the two first clamping portions 31 forming a first clamping space 301. The second clamping member 40 includes two second clamping portions 41 disposed opposite each other, with the gap between the two second clamping portions 41 forming a second clamping space 401. Both the first clamping member 30 and the second clamping member 40 are fixed to the horizontal column 20. For example, the first clamping member 30 and the second clamping member 40 can be fixed to the same end or different ends of the horizontal column 20 away from the vertical column 10, or respectively fixed to the ends of different horizontal columns 20 away from the vertical column 10. The central axes of the first clamping space 301 and the second clamping space 401 are oriented in different directions. For example, the central axis R1 of the first clamping space 301 can be horizontally oriented, while the central axis R2 of the corresponding second clamping space 401 can be vertically oriented or arranged at an acute angle to the horizontal. The center line equidistant from the two clamping portions is defined as the central axis. The first clamping space 301 and the second clamping space 401 are both used to limit the workpiece to be welded (not shown) for welding. Since the central axis orientation directions of the first clamping space 301 and the second clamping space 401 are different, welding tests of different types of workpieces to be welded can be achieved. For example, the workpiece to be welded can be a plate or a pipe. The assembly auxiliary member 50 is fixed to the top of the column 10 and at least one of the crossbars 20. The end surface of the assembly auxiliary member 50 facing away from the bottom end of the column 10 is recessed to form a docking groove 501. The docking groove 501 has two openings 5011 set apart from each other. There is a gap between the opening 5011 and the clamping member, so that the clamping member does not hinder the workpiece to be welded from being placed in the docking groove 501. The docking groove 501 is used to limit the abutment between different workpieces to be welded, or the docking groove 501 is used to limit the abutment between different workpieces to be welded before welding.

[0042] In practical applications, the workpieces to be welded can be transferred to the clamping member for welding testing after being assembled and abutted in the butt joint groove 501 .

[0043] In the present application, the welding test tool 100 is additionally provided with an assembly auxiliary part 50, so that different workpieces to be welded can be pre-adapted to each other before the welding test, thereby shortening the alignment time of the workpieces to be welded before welding, thereby improving the welding test efficiency. In addition, since the orientation directions of the central axes of the clamping spaces of the first clamping member 30 and the second clamping member 40 are different, when the workpiece to be welded is confined in different clamping members, welding tests at different angles can be completed, thereby avoiding the need to equip test tools with different structures and move between different test tools when conducting different welding tests, thereby further improving the test efficiency and reducing the test cost.

[0044] In some embodiments, the welding test fixture 100 further includes a third clamping member 60, which is secured to the horizontal column 20. The third clamping member 60 includes two opposing third clamping portions 61. The gap between the two third clamping portions 61 forms a third clamping space 601. The central axes of the third clamping space 601, the first clamping space 301, and the second clamping space 401 are oriented differently. The third clamping space 601 is used to position the workpiece for welding. Adding the third clamping member 60 further increases the number of welding types in the welding test. For example, the first clamping member 30, the second clamping member 40, and the third clamping member 60 can be secured to different horizontal columns 20 or the same column 20.

[0045] In some embodiments, the central axis R1 of the first clamping space 301 is oriented horizontally, the central axis R2 of the second clamping space 401 is oriented vertically, the second clamping space 401 is located on the side of the horizontal column 20 opposite the bottom end of the vertical column 10, and the central axis R3 of the third clamping space 601 is arranged at an acute angle to the horizontal direction. The third clamping space 601 is located on the side of the horizontal column 20 away from the bottom end of the vertical column 10. In this embodiment, the angle between the central axis R3 of the third clamping space 601 and the horizontal direction can be 45°. In other embodiments, the angle between the central axis R3 of the third clamping space 601 and the horizontal direction can be 60°, 30°, 50°, or 10°. The first clamping member 30 is fixed to the end of the horizontal column 20 away from the vertical column 10, the second clamping member 40 and the third clamping member 60 are fixed to the same end of the horizontal column 20 away from the vertical column 10, and the first clamping member 30 and the second clamping member 40 are fixed to different ends of the horizontal column 20 or to different horizontal columns 20. The position setting of different clamping parts is beneficial to reducing the spatial interference between each other on the one hand, and improving the convenience of welding examination on the other hand.

[0046] In some embodiments, the welding test tool 100 also includes a first nut 71 and a first bolt 72. The first nut 71 is fixed to a first clamping portion 31. Exemplarily, the first nut 71 can be fixed to an end face of the first clamping portion 31 away from the cross column 20 by welding. Exemplarily, a fixing through hole can also be provided in a first clamping portion 31 to fix the first nut 71 in the fixing through hole. Exemplarily, the first nut 71 can also be fixed to the end face of the first clamping portion 31 away from the other first clamping portion 31 by welding. At this time, the first bolt 72 can pass through the first clamping portion 31 to enter the first clamping space 301. The first bolt 72 is screwed onto the first nut 71, and the first bolt 72 can move toward or away from the other first clamping portion 31 to adjust the limiting tightness of the workpiece to be welded. Specifically, when the first bolt 72 is loosened, the workpiece to be welded is placed in the first clamping space 301, and then the first bolt 72 is tightened so that it abuts the workpiece to be welded. The workpiece to be welded is fastened by the first bolt 72 and a first clamping portion 31. The limiting tightness of the workpiece to be welded is adjusted by cooperating with the first bolt 72 and the first nut 71, which is conducive to the first clamping member 30 being adapted to workpieces to be welded of different sizes, thereby improving the adaptability of the first clamping member 30. In addition, when the limiting tightness of the workpiece to be welded can be adjusted, the size of the workpiece to be welded does not need to be fully adapted to the first clamping space 301, thereby reducing the installation resistance of the workpiece to be welded, and further improving the ease of use of the welding test tool 100.

[0047] In some embodiments, there are at least two second clamping members 40. In this embodiment, there are two second clamping members 40. When viewed along the extension direction of the crossbar 20, the second clamping portions 41 of two adjacent second clamping members 40 are spaced apart and arranged in a one-to-one correspondence. Increasing the number of second clamping members 40 improves the stability of the clamping, thereby allowing the second clamping members 40 to accommodate heavier workpieces. The welding test jig 100 also includes a second nut 81 and a second bolt 82. The second nut 81 is secured between one second clamping portion 41 and the adjacent second clamping portion 41 of the other second clamping member 40, illustratively by welding. The second bolt 82 is threadedly coupled to the second nut 81 and can be moved toward or away from the other second clamping portion 41 to adjust the tightness of the clamping position of the workpiece to be welded. Similarly, the coordination of the second bolt 82 and the second nut 81 improves the adaptability of the second clamping member 40 and further enhances the ease of use of the welding test jig 100. Similarly, when installing the workpiece to be welded, the second bolt 82 can be loosened. When the workpiece to be welded is placed in all the second clamping spaces 401, the second bolt 82 can be tightened so that the second bolt 82 can press against the workpiece to be welded, and the second bolt 82 can cooperate with the second clamping part 41 to tighten the workpiece to be welded.

[0048] In some embodiments, the welding test jig 100 further includes a third nut 83 and a third bolt 84. The third nut 83 is secured to one of the third clamping portions 61. For example, the third nut 83 can be secured to the end surface of one third clamping portion 61 facing away from the horizontal column 20, or to the end surface of one third clamping portion 61 facing away from the other third clamping portion 61. In this case, the third bolt 84 can be inserted through the third clamping portion 61. A fixing through-hole can be provided in each third clamping portion 61, into which the third nut 83 is secured. The third bolt 84 is threadedly coupled to the third nut 83 and can be moved toward or away from the other third clamping portion 61 to adjust the tension of the welded workpiece. Similarly, the combination of the third bolt 84 and the third nut 83 improves the adaptability of the third clamping portion 60 and further enhances the ease of use of the welding test jig 100. The principle of adjusting the tension of the third bolt 84 and the third nut 83 is similar to that of other bolt and nut combinations and will not be further described.

[0049] In some embodiments, the second clamping member 40 further includes a first connecting portion 42, which is fixed between the two second clamping portions 41 to form a second clamping space 401. The first connecting portion 42 is fixed to the horizontal column 20. For example, the first connecting portion 42 and the second clamping portion 41 can be integrally formed or fixed by welding. For example, the first connecting portion 41 can be fixed to the horizontal column 20 by welding. The addition of the first connecting portion 42 to the second clamping member 40 facilitates installation of the second clamping member 40 while also increasing the fixing strength.

[0050] In some embodiments, the third clamping member 60 further includes a second connecting portion 62, which is fixed between the two third clamping portions 61 to form a third clamping space 601. For example, the second connecting portion 62 and the third clamping portion 61 can be fixed by integral molding or welding. The second connecting portion 62 is fixed to the horizontal column 20. For example, the second connecting portion 62 can be fixed to the horizontal column 20 by welding. Similarly, the addition of the second connecting portion 62 to the third clamping member 60 facilitates the installation of the third clamping member 60 while also improving the fixing strength.

[0051] In some embodiments, there are two transverse posts 20, which are positioned opposite each other and fixed to different sides of the top of the upright post 10. For example, the transverse posts 20 can be fixed by welding. The first clamping member 30 and the second clamping member 40 are fixed to different transverse posts 20, and the assembly auxiliary member 50 is fixed to the top of the upright post 10 and each transverse post 20, thereby improving the bearing strength of the assembly auxiliary member 50.

[0052] In some embodiments, the column 10 includes a first column portion 11 and a second column portion 12. A cross column 20 is fixed to one end of the first column portion 11. The end surface of the other end of the first column portion 11 is recessed to form a movable cavity 110. One end of the second column portion 12 is disposed within the movable cavity 110, allowing the first column portion 11 and the second column portion 12 to rotate and move between them. The welding test fixture 100 also includes a fourth nut 91 and a fourth bolt 92. The fourth nut 91 is fixed to the side wall of the movable cavity 110. For example, the fourth nut 91 can be fixed to the outer surface of the side wall of the movable cavity 110 by welding, or a fixing through hole can be provided in the side wall of the movable cavity 110, and the fourth nut 91 can be fixed in the fixing through hole. The fourth bolt 92 is threadedly connected to the fourth nut 91 and can be moved toward or away from the movable cavity 110 to adjust the tightness of the socket between the first column portion 11 and the second column portion 12. In practice, the fourth bolt 92 can be loosened to rotate or raise or lower the first column 11 to adjust the welding test jig 100 to the most convenient height or angle. Therefore, the coordination between the column 10, the fourth nut 91, and the fourth bolt 92 improves the ease of use of the welding test jig 100.

[0053] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
