Description

Technical Field

[0001] The utility model relates to the technical field of elbow welding, in particular to a elbow welding clamping mechanism. Background Art

[0002] At present, elbow pipe connection generally adopts welding to weld two sets of elbow pipes into a complete set of pipes. When welding, the ends of the two sets of elbow pipes are butt-jointed and then welded quickly. However, the following problems are prone to occur during the welding process:

[0003] When clamping the elbow pipe, the elbow at the bottom needs to be fixed by manual support. However, when manually supporting the elbow pipe, it is difficult to ensure the stability of the bottom elbow pipe. This method can easily cause the elbow pipe at the bottom to shake during welding, resulting in poor welding effect between the two sets of elbows and inconvenience in use.

[0004] Therefore, we make improvements to this and propose a elbow welding clamping mechanism. Utility Model Content

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0020] Example: Figures 1 to 4 As shown, the utility model provides a pipe elbow welding clamping mechanism, comprising a base 1, a mounting plate 4 rotatably provided on the base 1, a clamping assembly provided on the mounting plate 4, and a clamping assembly including a clamping plate 11. The clamping plate 11 is arranged in an arc-shaped structure, and two groups of clamping plates 11 are provided. Both groups of clamping plates 11 are slidably provided in the horizontal direction of the mounting plate 4. Both groups of clamping plates 11 are provided with a clamping groove 111, and the inner side edge of the clamping groove 111 is provided with a rounded corner 112. By utilizing the movable clamping plate 11 provided in the horizontal direction of the mounting plate 4, it is possible to more easily clamp the bottom of the pipe elbow to be welded, further improve the stability of the pipe elbow during welding, and thereby improve the welding effect and quality of the pipe elbow.

[0021] The mounting plate 4 is provided with a slide groove 41, and a slider 113 is fixedly connected to the bottom of the clamping plate 11. The slider 113 is slidably connected to the slide groove 41, and the slider 113 is slidably arranged in the slide groove 41. By sliding the slider 113 in the slide groove 41, it is easier to limit the moving path of the clamping plate 11, and it is more convenient and quick to use.

[0022] A second threaded rod 12 is threadedly connected to the chute 41. The end of the second threaded rod 12 closest to the clamping plate 11 is rotatably connected to the slider 113 via a bearing 121. By utilizing the second threaded rod 12 threadedly connected to the chute 41, the horizontal position of the clamping plate 11 on the mounting plate 4 can be more easily adjusted and fixed, thereby enabling the clamping plate 11 to clamp curved pipes of different widths.

[0023] Vertical rods 5 are fixed on both sides of the mounting plate 4, and a fixing assembly is provided for sliding in the vertical direction of the vertical rod 5. By sliding the fixing assembly in the vertical direction of the vertical rod 5, it is easier to clamp and fix the upper part of the bent pipe; the fixing assembly includes a clamp 8, and an anti-slip pad 81 is provided on the curved surface of the clamp 8; by providing the clamp 8, it is easier to clamp and fix the bent pipe, and by fixing the anti-slip pad 81 fixedly connected to the curved surface of the clamp 8, the friction between the clamp 8 and the bent pipe to be clamped can be further increased, and it is more convenient to use.

[0024] A limiting slot 51 is provided inside the vertical rod 5, and the top of the vertical rod 5 is fixedly connected to the second motor 6. The output shaft of the second motor 6 is vertically downward and fixedly connected to the first threaded rod 10 through a coupling. By setting the second motor 6, it is easier to drive the first threaded rod 10 to rotate; the end of the first threaded rod 10 away from the second motor 6 is rotatably connected to the inner bottom surface of the limiting slot 51 through the rotating shaft 101, and the first threaded rod 10 is threadedly connected to the limiting block 9. By threading the limiting block 9 on the first threaded rod 10, it is easier to drive the limiting block 9 to move in the vertical direction and to adjust the clamping position of the clamp 8; the limiting block 9 is fixedly connected to the electric push rod 7, and the clamp 8 is fixedly connected to the output end of the electric push rod 7. By fixing the clamp 8 to the output end of the electric push rod 7, it is easier to adjust and fix the clamping positions of the clamps 8 on both sides, which is more convenient and quicker to use.

[0025] A first motor 3 is fixedly connected to the base 1. By setting the first motor 3, it is easier to drive the mounting plate 4 to rotate, so that it is easier to weld the elbows at different angles; a support ring 2 is fixedly connected to the base 1, and a guide ring 21 is fixedly connected to the support ring 2. A guide groove 42 is provided at the bottom of the mounting plate 4, and the guide ring 21 is slidingly connected to the guide groove 42; by utilizing the sliding connection between the guide ring 21 fixedly connected to the support ring 2 and the guide groove 42 provided at the bottom of the mounting plate 4, it is easier to support and guide the mounting plate 4.

[0026] During operation, when two bent pipes need to be welded, first place the bottom of the bent pipe to be welded in the slot 111 on the clamping plate 11, and then adjust the position of the clamping plates 11 on both sides by screwing the second threaded rod 12 until the clamping plates 11 on both sides are adjusted to conflict with the two sides of the bent pipe to be welded, and then use the second motor 6 to drive the first threaded rod 10 to rotate, and use the rotation of the first threaded rod 10 to drive the limit block 9 threadedly connected thereto to move in the vertical direction, and then use the electric push rod 7 to adjust the position of the clamp 8 so that the clamp 8 clamps and fixes the top of the bent pipe to be welded, and then use an external welding device to weld it.
