Description

Technical Field

[0001] This utility model relates to the technical field of welding equipment, specifically a tooling for improving the verticality of stud welding. Background Technology

[0002] During the stud welding process of LNG carrier MARK III type studs, due to the nature of the process, the initial contact is only with the aluminum welding head of the stud itself. The perpendicularity of the stud weld directly affects the installation of the insulation plate and corrugated plate. Properly controlling the perpendicularity of the stud weld during the welding process can effectively reduce the difficulty of subsequent installation and welding.

[0003] Previously, the studs were inserted into the copper tube sleeve. After the ceramic gasket was secured by the retaining ring on the wooden wedge, the studs were limited and pressed against the workpiece during welding. The welder's experience and feel were used to ensure the perpendicularity of the studs during welding. Relying solely on experience and feel, the welder spent a lot of time and effort during welding, resulting in low welding efficiency.

[0004] Document CN 213614726 U discloses a perpendicularity testing fixture for stud welding, including: a connecting post with a locking part connected to the stud welding gun head, and a perpendicularity testing component detachably connected to the connecting post. The perpendicularity testing component and the connecting post are coaxially arranged, and the perpendicularity testing component has a testing plane perpendicular to the axis. If only one surface is in contact, skewness is likely to occur.

[0005] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the aforementioned issues, this utility model discloses a tooling for improving the verticality of stud welding. By rationally controlling the verticality of the stud welding during the welding process, the difficulty of subsequent installation and welding can be effectively reduced.

[0007] The technical solution of this utility model is as follows: a tooling for improving the verticality of stud welding, including a limiting plate located at the end of the welding gun, the limiting plate and the welding gun are connected by a welding gun connecting rod, a stud hole is provided at the center of the limiting plate for placing the stud, a planar limiting hole is provided on the limiting plate, a ceramic ring is provided in the limiting hole, and a limiting rod is fixedly provided in the limiting hole, with the bottom of the limiting rod on the same plane.

[0008] By adopting the above technical solution, when the welding torch is welding the stud, the three points of the limiting rod form a surface to abut against the welding surface, and the stud to be welded is located within the three limiting rods, so that the stud and the welding surface always remain perpendicular, thus improving the perpendicularity of the stud during welding.

[0009] Preferably, the limiting plate is triangular in shape, parallel to the horizontal plane, and the limiting holes are located inside the three corners of the limiting plate.

[0010] By adopting the above technical solution, the limiting rod can pass through the limiting hole, so that a plane can be formed between the bottoms of the limiting rod.

[0011] Preferably, the bottom of the limiting rod is provided with a limiting abutment plate, and both ends of the limiting rod are located on the outside of the limiting plate.

[0012] Preferably, the diameter of the limiting abutment plate is larger than the diameter of the limiting rod, and the lower plane of the limiting abutment plate is flush with the horizontal line.

[0013] By adopting the above technical solution, the connection position between the limiting plate and the limiting rod, that is, the distance between the end of the limiting rod and the limiting plate, can be adjusted according to the actual welding requirements. The limiting abutment plate abuts against the welding surface, so that the limiting abutment plates form a surface parallel to the welding surface.

[0014] Preferably, two of the outer sides of the limiting hole, i.e. the outer side of the limiting plate, are provided with welding gun connection holes, which are connected to the welding gun through the welding gun connection rod.

[0015] By adopting the above technical solution, the limiting plate can be connected to the welding gun via the welding gun connecting rod.

[0016] Preferably, the stud hole is located between the limiting holes, a stud body passes through the stud hole, the upper part of the stud body is connected to the conductive tip of the welding gun, and the lower end is provided with a ceramic ring for limiting.

[0017] By adopting the above technical solution, a surface parallel to the welding surface is formed at the bottom of the limiting abutment plate. In this way, the stud body and the welding surface are perpendicular, that is, the stud body inside the stud body is also perpendicular to the welding surface, thus achieving the effect of vertical welding.

[0018] Preferably, the stud body contains a stud, the top of the stud is connected to the conductive nozzle, and the lower end is located inside the inner hole of the ceramic ring.

[0019] By adopting the above technical solution, the inner wall of the ceramic ring reflects the heat of the electric arc, so that the electric arc is focused on the welding area, reducing heat loss, preventing heat splashing, and preventing sparks from penetrating into the equipment.

[0020] The advantages of this utility model are as follows: 1. This utility model sets limiting plates at each corner of the triangular limiting plate, and the limiting abutment plates at the ends of the limiting plates are on the same plane, and the plane formed between the limiting abutment plates and the welding surface are kept parallel, so that the stud is perpendicular to the welding surface.

[0021] 2. This utility model improves working efficiency by simultaneously abutting the limiting plate around the welding point on the welding surface, allowing the stud to be directly perpendicular to the welding surface.

[0022] 3. This utility model can effectively reduce the difficulty of subsequent installation and welding by reasonably controlling the perpendicularity of the stud weld during the welding process. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figure 1-4 As shown, a tooling for improving the perpendicularity of stud welding includes a limiting plate 1 located at the end of a welding torch. The limiting plate 1 and the welding torch are connected by a welding torch connecting rod 7. A stud hole 3 is provided at the center of the limiting plate 1, in which a stud 7 is placed. A planar limiting hole 2 is provided on the limiting plate 1, in which a ceramic ring 10 is provided. A limiting rod 4 is fixedly provided in the limiting hole 2, with the bottom of the limiting rod 4 on the same plane. When the welding torch welds the stud 9, the three points of the limiting rod 4 form a surface to abut against the welding surface, and the stud 9 to be welded is located within the three limiting rods 4, so that the stud 9 and the welding surface always remain perpendicular, thus improving the perpendicularity of the stud 9 during welding.

[0027] The limiting plate 1 is triangular in shape and parallel to the horizontal plane. The limiting holes 2 are located inside the three corners of the limiting plate 1. The limiting rods 4 can pass through the limiting holes 2, so that the bottoms of the limiting rods 4 form a plane.

[0028] The bottom of the limiting rod 4 is provided with a limiting abutment plate 5. Both ends of the limiting rod 4 are located outside the limiting plate 1. The diameter of the limiting abutment plate 5 is larger than the diameter of the limiting rod 4. The lower plane of the limiting abutment plate 5 is flush with the horizontal line. The connection position between the limiting plate 1 and the limiting rod 4, that is, the distance between the end of the limiting rod 4 and the limiting plate 1, can be adjusted according to the actual welding requirements. The limiting abutment plate 5 abuts against the welding surface, so that the limiting abutment plates 5 form a surface parallel to the welding surface.

[0029] Two of the outer sides of the limiting hole 2, i.e. the outer side of the limiting plate 1, are provided with welding gun connection holes 6. The welding gun connection holes 6 are connected to the welding gun through the welding gun connection rod 7. The limiting plate 1 can be connected to the welding gun through the welding gun connection rod 7.

[0030] The stud hole 3 is located at the center of the limiting plate 1 between the limiting holes 2. The stud body 8 passes through the stud hole 3. The upper part of the stud body 8 is connected to the conductive nozzle 11 of the welding gun, and the lower end is provided with a ceramic ring 10 for limiting. The bottom of the limiting abutment plate 5 forms a surface parallel to the welding surface. In this way, the stud body 3 and the welding surface are perpendicular, that is, the stud 9 inside the stud body 3 is also perpendicular to the welding surface, so that the vertical welding effect can be achieved.

[0031] The stud body 3 contains a stud 9. The top of the stud 9 is connected to the conductive nozzle 11, and the lower end is located inside the inner hole of the ceramic ring 10. The inner wall of the ceramic ring 10 reflects the heat of the electric arc, so that the electric arc is focused on the welding area, reducing heat loss, preventing heat splashing, and preventing sparks from penetrating into the equipment.

[0032] When the welding torch is used for welding, the limiting abutment plate 5 at the end of the limiting rod 4 on the limiting plate 1 abuts against the welding surface. At this time, the stud 9 in the stud body 8 and the welding surface are kept in a perpendicular position, which can ensure the perpendicularity between the stud 9 and the welding surface during welding.

[0033] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
