Description

Technical Field

[0001] This utility model relates to the field of connecting flange processing technology, and in particular to a connecting flange welding equipment. Background Technology

[0002] A flange is a component used to connect pipes or equipment. It connects two flanges together using bolts, nuts, gaskets, and other elements to form a sealed structure. Flange connections are convenient to use, can withstand high pressure, and are widely used in various applications such as industrial pipelines, domestic pipelines, fire protection, gas, hot and cold water, and air conditioning.

[0003] During the processing of connecting flanges, welding equipment is often used to weld the connecting flange to the pipeline. Since existing welding equipment can only fix the pipeline or connecting flange individually, it is necessary to manually weld a portion of the connecting flange to the pipeline first, and then fix the connecting flange or pipeline with the welding equipment to rotate and weld the connecting flange to the pipeline. When performing manual welding, the connecting flange and pipeline need to be held down manually, which makes the welding process somewhat dangerous. It also requires welding from both manual and equipment aspects, making the operation quite cumbersome and time-consuming. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a connecting flange welding device to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flange welding device includes a worktable, a rotating assembly at the bottom of the worktable, a turntable at the top of the worktable via the rotating assembly, a cavity inside the turntable, a sliding groove extending through the top of the turntable, a driving assembly inside the cavity, a screw inside the cavity via the driving assembly, a fixed plate rotatably connected to the surface of the screw and fixedly connected to the inner wall of the cavity, a moving rod threadedly connected to the surface of the screw and slidably connected to the sliding groove, a lifting assembly at the top of the worktable, a rotating block at the top of the worktable via the lifting assembly, a pressure plate rotatably connected to the surface of the rotating block, and a welding assembly at the top of the worktable.

[0007] Preferably, the rotating assembly includes a rotary motor disposed at the bottom of the worktable, the output end of the rotary motor extending through the worktable to the top of the worktable and having a rotating rod fixedly installed thereon, the rotating rod being fixedly connected to the turntable.

[0008] Preferably, the drive assembly includes a drive motor disposed at the bottom of the inner wall of the cavity, a rotating shaft fixedly mounted at the output end of the drive motor, a first bevel gear fixedly mounted on the surface of the rotating shaft, a second bevel gear meshing on the surface of the first bevel gear, and the second bevel gear being fixedly connected to a screw.

[0009] Preferably, the lifting assembly includes a support frame disposed on the top of the worktable, a hydraulic push rod is fixedly installed on the top of the support frame, and the output end of the hydraulic push rod is fixedly connected to the rotating block.

[0010] Preferably, the welding assembly includes a first electric push rod disposed on the top of the workbench, a first mounting plate fixedly mounted on the output end of the first electric push rod, a second electric push rod fixedly mounted inside the first mounting plate, a second mounting plate fixedly mounted on the output end of the second electric push rod, and a welding torch fixedly mounted on the second mounting plate.

[0011] Preferably, the bottom of the workbench is fixedly equipped with support legs, and the number of support legs is multiple.

[0012] Preferably, there are multiple movable rods, and the multiple movable rods are distributed in a circular array.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This flange welding equipment places the flange on a turntable, and the drive assembly causes the screw to rotate simultaneously, causing the moving rod to move along the slide groove towards the center to clamp the flange. Then, the lifting assembly causes the rotating block and pressure plate to move downwards to press the pipe. During the welding process, because the pressure plate and rotating block are rotatably connected, when the rotating assembly drives the turntable to rotate, the flange and pipe can rotate together until the welding operation is completed. This allows the welding equipment to fix the flange and pipe simultaneously, and the flange and pipe can rotate synchronously. Therefore, welding can be performed only by the welding equipment, eliminating the need for manual welding of a portion of the flange and pipe, thus making the welding operation safer and reducing the welding time.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1-4A flange welding device includes a workbench 1, a rotating assembly at the bottom of the workbench 1, and a turntable 4 at the top of the workbench 1 via the rotating assembly. The rotating assembly includes a rotary motor 2 located at the bottom of the workbench 1, with the output end of the rotary motor 2 extending through the workbench 1 to the top of the workbench 1 and fixedly mounted with a rotating rod 3. The rotating rod 3 is fixedly connected to the turntable 4 to provide driving force for the rotation of the turntable 4. A cavity 5 is formed inside the turntable 4, and a sliding groove 6 is provided through the top of the turntable 4. A driving assembly is installed inside the cavity 5, and a screw 11 is installed inside the cavity 5 via the driving assembly. A fixing plate 12 is rotatably connected to the surface of the screw 11 and fixedly connected to the inner wall of the cavity 5. A moving rod 13 is threadedly connected to the surface of the screw 11. There are multiple moving rods 13 arranged in a circular array, and the moving rods 13 are slidably connected to the slide groove 6. The driving assembly includes a drive motor 7 located at the bottom of the inner wall of the cavity 5. A rotating shaft 8 is fixedly installed at the output end of the drive motor 7. A first bevel gear 9 is fixedly installed on the surface of the rotating shaft 8. A second bevel gear 10 is meshed on the surface of the first bevel gear 9. The second bevel gear 10 is fixedly connected to the screw 11, so that the screw 11 can rotate simultaneously, allowing the moving rods 13 to move towards the center simultaneously. This facilitates fixing the connecting flange at the center position of the turntable 4, which in turn facilitates better subsequent welding operations. A lifting assembly is provided on the top of the worktable 1, and a rotating block 16 is provided on the top of the worktable 1 via the lifting assembly. A pressure plate 17 is rotatably connected to the surface of block 16. The lifting assembly includes a support frame 14 mounted on the top of the workbench 1. A hydraulic push rod 15 is fixedly mounted on the top of the support frame 14. The output end of the hydraulic push rod 15 is fixedly connected to the rotating block 16, which facilitates the up-and-down movement of the rotating block 16, thereby facilitating the subsequent clamping of the pipe. A welding assembly is provided on the top of the workbench 1. The welding assembly includes a first electric push rod 18 mounted on the top of the workbench 1. A first mounting plate 19 is fixedly mounted on the output end of the first electric push rod 18. A second electric push rod 20 is fixedly mounted inside the first mounting plate 19. A second mounting plate 21 is fixedly mounted on the output end of the second electric push rod 20. A welding torch 22 is fixedly mounted on the second mounting plate 21, which facilitates the clamping of the pipe and connecting flange. Welding is performed at the connection point. Multiple support legs 23 are fixedly installed at the bottom of the workbench 1. In this flange welding equipment, the flange is placed on the turntable 4. The drive assembly rotates the screw 11, causing the moving rod 13 to move along the slide groove 6 towards the center, clamping the flange. Then, the lifting assembly moves the rotating block 16 and pressure plate 17 downwards to press the pipe. During welding, because the pressure plate 17 is rotatably connected to the rotating block 16, the rotating assembly drives the turntable 4 to rotate, causing the flange and pipe to rotate together until the welding operation is complete. This allows the welding equipment to simultaneously fix the flange and pipe, and the flange and pipe can rotate synchronously.Therefore, welding can be performed solely using welding equipment, eliminating the need for manual welding of connecting flanges and pipes. This allows for safer welding operations and reduces the time required for welding.

[0021] All electrical components mentioned in this article are connected to an external controller, which can be a conventional known device such as a computer for control.

[0022] In use: Place the connecting flange on the turntable 4, start the drive motor 7 to rotate the rotating shaft 8, which in turn rotates the first bevel gear 9 and the second bevel gear 10, causing the screw 11 to rotate simultaneously. This causes the moving rod 13 to move along the slide groove 6 towards the center until the connecting flange is clamped. Then, insert the pipe into the connecting flange, start the hydraulic push rod 15 to move the rotating block 16 and the pressure plate 17 downwards, causing the pressure plate 17 to press the pipe. Then, start the first electric push rod 18 and the second electric push rod 20 to move the welding torch 22 up, down, left, and right to the appropriate position. Start the welding torch 22 to weld the connection between the pipe and the connecting flange. Then, start the rotary motor 2 to rotate the rotating rod 3, causing the turntable 4 to rotate. Since the pressure plate 17 is rotatably connected to the rotating block 16, the connecting flange and the pipe can rotate together until the welding operation is completed.

[0023] In summary, this flange welding equipment places the flange on the turntable 4. The drive assembly rotates the screw 11, causing the moving rod 13 to move along the slide groove 6 towards the center to clamp the flange. Then, the lifting assembly moves the rotating block 16 and pressure plate 17 downwards to press the pipe. During welding, because the pressure plate 17 is rotatably connected to the rotating block 16, the rotating assembly drives the turntable 4 to rotate, causing the flange and pipe to rotate together until the welding operation is complete. This allows the welding equipment to simultaneously fix the flange and pipe, and the flange and pipe can rotate synchronously. Therefore, welding only requires the equipment to be applied to the ground, eliminating the need for manual welding of parts of the flange and pipe. This makes the welding operation safer, reduces welding time, and solves the problems mentioned in the background art.
