Description

Technical Field

[0001] This utility model belongs to the field of flange welding technology, specifically a flange welding device. Background Technology

[0002] A flange welding apparatus is a tool or device specifically designed to assist in the precise, secure, and efficient welding of flanges to pipes or joints. Its core purpose is to solve the precision and efficiency problems encountered when butt-welding flanges to pipes or joints.

[0003] A search revealed that patent document CN118768830A discloses a positioning device for flange joint welding processing, which includes a positioning worktable and a flange joint body. The top of the positioning worktable is provided with a synchronous positioning mechanism, and the back of the positioning worktable is provided with a fume treatment mechanism. The synchronous positioning mechanism includes a pneumatic positioning unit and a pneumatic control unit.

[0004] The above design, through the cooperation of the support tube and the limiting sleeve, can simultaneously provide temporary positioning for five flange joint bodies. Furthermore, through the design of the connecting air pipe, it can absorb the gas in the inner cavity of the hollow ring seat, causing a negative pressure to be generated synchronously in the inner cavity of the support tube. This negative pressure drives the plug-in to move downward, limiting the top of the flange joint body. This achieves the function of simultaneously positioning five flange joint bodies, avoiding the need to disassemble and assemble individual flange joint bodies during welding, and improving the welding efficiency of this structure.

[0005] In actual use, the above design uses the positioning unit and the pneumatic control unit to realize the function of simultaneously positioning the five flange joint bodies. However, considering that the weld is prone to uneven shrinkage during the welding process of the flange joint, resulting in reduced weld strength and weld cracks, the quality and strength of the weld are affected.

[0006] Therefore, a flange welding device is proposed to address the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figures 1-5 This utility model provides a flange welding device, including a base 1, a second groove 15 on the top of the base 1, and two first clamping blocks 16 slidably installed on the inner surface of the second groove 15; it also includes a welding mechanism for welding flanges; the welding mechanism includes a toothed ring 2, which is fixedly installed on the top of the base 1, and a sliding plate 24 is slidably connected to the outer surface of the toothed ring 2. A first electric telescopic rod 27 is fixedly installed on the top of the sliding plate 24, and a first mounting box 28 is fixedly connected to the output end of the first electric telescopic rod 27. Two mounting rods 29 are slidably installed in the inner cavity of the first mounting box 28, and a first bidirectional threaded rod is rotatably installed in the inner cavity of the first mounting box 28. The first bidirectional threaded rod is threadedly connected to the two mounting rods 29, and a first motor is fixedly connected to one end of the first bidirectional threaded rod. The first motor is fixedly installed on one side of the first mounting box 28, and a welding torch 291 is fixedly installed at one end of the mounting rod 29.

[0029] In the process of welding flange joints, existing flange welding equipment is prone to uneven shrinkage of the weld, which leads to reduced weld strength and the appearance of weld cracks, affecting the quality and strength of the weld.

[0030] In use, the flange is first placed in the inner cavity of the second groove 15. Then, the two first clamping blocks 16 clamp the flange together. Next, the joint to be welded to the flange is placed on top of the flange. At this time, the first mounting box 28 is moved by extending or shortening the output end of the first electric telescopic rod 27 according to the thickness of the flange. The first mounting box 28 moves the mounting rod 29, and the two mounting rods 29 rotate according to the diameter of the flange and the joint by the first motor. The first bidirectional threaded rod drives the two mounting rods 29 to move the welding gun 291 synchronously to the welding point. Further, the first mounting box 28 is rotated by the rotation of the sliding plate 24. At this time, the two welding guns 291 weld on both sides of the flange at the same time. This reduces the probability of uneven shrinkage of the weld when a single welding gun welds the flange and the joint, which leads to reduced weld strength and weld cracks, thereby increasing the quality and strength of the weld.

[0031] Furthermore, such as Figure 2 and Figure 3 As shown, the base 1 has a first groove 11 at its bottom. A first gear 13 is rotatably mounted on the inner surface of the first groove 11. Two racks 12 are slidably mounted in the inner cavity of the first groove 11. Both racks 12 mesh with the first gear 13. A third motor 14 is fixedly mounted at the bottom of the first gear 13. The third motor 14 is fixedly mounted at the bottom of the base 1. Two first clamping blocks 16 are fixedly connected to the two racks 12 respectively.

[0032] In use, the first gear 13 is rotated by the output shaft of the third motor 14. The first gear 13 further drives the two racks 12 to slide in the inner cavity of the first groove 11. The first groove 11 can limit the two racks 12. When the racks 12 slide, they will carry the first clamping block 16 to slide in the inner cavity of the second groove 15. This can make the second groove 15 clamp the flange.

[0033] Furthermore, such as Figure 4 As shown, the toothed ring 2 has a third groove 21 on its top, and a plurality of cylinders 22 are slidably mounted on the inner surface of the third groove 21. The plurality of cylinders 22 are rotatably mounted on the bottom of the slide plate 24.

[0034] The outer surface of the toothed ring 2 is provided with a fourth groove 23, and the slide plate 24 is slidably installed on the inner surface of the fourth groove 23. The toothed ring 2 is meshed with a second gear 26, and a fourth motor 25 is fixedly connected to one side of the second gear 26. The fourth motor 25 is fixedly connected to the slide plate 24.

[0035] When this utility model is in use, the welding torch 291 needs to make a circular motion during welding. The output shaft of the fourth motor 25 drives the second gear 26 to rotate. The second gear 26 can slide along the gear ring 2 by meshing with the gear ring 2. At this time, the third groove 21 slides on the inner surface of the third groove 21, and the bottom of the slide plate 24 slides on the inner surface of the fourth groove 23. This makes the slide plate 24 slide more stably.

[0036] Furthermore, such as Figure 5 As shown, a support frame 3 is fixedly installed on the top of the base 1, and a second electric telescopic rod 31 is fixedly connected to the top of the support frame 3. A second mounting box 32 is fixedly connected to the output end of the second electric telescopic rod 31. Two second clamping blocks 33 are slidably installed on the inner surface of the second mounting box 32. A sliding rod 34 is fixedly installed on the inner surface of the second mounting box 32, and the sliding rod 34 is slidably connected to the two second clamping blocks 33.

[0037] A second bidirectional threaded rod is rotatably mounted on the inner surface of the second mounting box 32. The second bidirectional threaded rod is threadedly connected to two second clamping blocks 33. A second motor is fixedly connected to one end of the second bidirectional threaded rod. The second motor is fixedly mounted on one side of the second mounting box 32.

[0038] In use, to increase the stability of the joint during welding, the second motor drives the second bidirectional threaded rod to rotate. The second bidirectional threaded rod, in conjunction with the slide rod 34, limits the two second clamping blocks 33, thereby driving the two second clamping blocks 33 to slide towards each other. When the two second clamping blocks 33 approach each other, the top of the joint is pressed tightly against the inner wall of the second mounting box 32. The two second clamping blocks 33 approach each other and clamp the two sides of the joint to fix the joint. At this time, the output end of the second electric telescopic rod 31 extends, so that the bottom of the joint is pressed tightly against the flange for stable welding.

[0039] Working principle: When using this utility model, firstly, the flange is placed in the second groove 15. Then, the output shaft of the third motor 14 drives the first gear 13 to rotate. The first gear 13, in conjunction with the first groove 11, limits the two racks 12, causing them to slide. As the two racks 12 slide, they respectively carry the two first clamping blocks 16 to slide on the inner surface of the second groove 15, thereby achieving the purpose of clamping and fixing the flange. Next, the top of the joint is pressed against the inner wall of the second mounting box 32. Then, the second bidirectional threaded rod drives the two second clamping blocks 33 to move closer to each other to clamp the joint. The output end of the second electric telescopic rod 31 extends and moves the joint downward so that the joint is pressed against the top of the flange, and welding can then begin.

[0040] In use, the height of the welding torch 291 is first adjusted according to the height of the flange and the joint connection. This is achieved by extending and shortening the output end of the first electric telescopic rod 27 to move the first mounting box 28. Then, the distance between the two welding torches 291 is adjusted according to the diameter of the contact surface between the joint and the flange. This is achieved by rotating the first bidirectional threaded rod with the first motor. During welding, the center of the flange overlaps with the center of the toothed ring 2, and the path of the two welding torches 291 moving towards each other is the diameter of the toothed ring 2.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
