Description

Technical Field

[0001] The utility model relates to the field of welding devices, in particular to a balancing valve flange welding device. Background Art

[0002] A balancing valve is a valve with a special function. The valve itself is not special; it differs only in its function and location. In some industries, due to the large pressure or flow differences between different parts of the medium (various flowable substances) in the pipeline or container, a valve is installed between the corresponding pipelines or containers to reduce or balance the difference. This valve is used to adjust the relative balance of pressure on both sides or to achieve flow balance by diverting the flow. This valve is called a balancing valve. During the balancing valve processing, a welding device is used to weld the balancing valve to the flange.

[0003] However, in the prior art, when the welding device is in use, the worker needs to frequently rotate the balancing valve and the flange to achieve annular welding, which undoubtedly reduces the welding efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a balancing valve flange welding device.

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows: a balancing valve flange welding device includes an operating table, a slide groove is provided at the upper end of the operating table, a slider is slidably connected inside the slide groove, the upper end of the slider is fixedly connected to a gear plate, the upper end of the operating table is fixedly connected to a support block near the slide groove, an electric push rod is provided on the front side of the support block, the upper end of the operating table is fixedly connected to a fixed block, a bearing is provided inside the fixed block, the inner ring of the bearing is fixedly connected to a rotating shaft, one end of the rotating shaft is fixedly connected to a gear, and the other end of the rotating shaft is provided with a cylinder, and the right end of the cylinder is fixedly connected to a fixed disk.

[0006] Preferably, a support block is fixedly connected to the middle of the upper end of the operating table, a ball is provided inside the support block, a balancing valve body is provided at the upper end of the support block, a flange body is provided on one side of the fixed plate, and a connecting rod is fixedly connected to the upper end of the operating table near the support block, and a welding gun is provided on one side of the connecting rod.

[0007] Preferably, the outside of the fixed disk is fixedly connected to an arc-shaped plate, one side of the arc-shaped plate is provided with a guide groove, the inside of the guide groove is movably connected to a guide rod, one end of the guide rod is fixedly connected to a clamping ring, the right side of the clamping ring is fixedly connected to a fixing clamp, the inside of the clamping ring is movably connected to a clamping ring, the left side of the clamping ring is fixedly connected to a bolt, and a threaded hole is provided inside the arc-shaped plate.

[0008] Preferably, the slider slides in the slide groove through the gear plate and the electric push rod.

[0009] Preferably, the fixing clamp is movably connected to the bolt through a clamping ring and a clamping ring.

[0010] Preferably, the arc-shaped plates are in multiple groups and are arranged at equal angles outside the fixed disk.

[0011] By adopting the above technical solution, by turning on the electric push rod, the electric push rod pushes the gear plate to move, thereby driving the gear to rotate. While the gear rotates, it will drive the rotating shaft, cylinder, and fixed plate to rotate, thereby realizing the change of the welding points between the flange body and the balancing valve body. The welding gun can perform circular welding around these welding points. During the rotation of the gear, the slider will slide inside the slide groove. With the cooperation of the slider and the slide groove, the stability of the flange body and the balancing valve body during rotation can be increased. The rotating shaft, bearings, gears, cylinders, electric push rods, and gear plates can be used to rotate the flange body and the balancing valve body, and then the connection between the two components can be welded. Compared with traditional manual rotary welding, this welding method is more efficient.

[0012] By adopting the above technical solution, by rotating the bolt, under the action of the threaded hole inside the arc plate, the bolt pushes the clamping ring and the clamping ring to one side, so that the fixing clamp is tightly attached to the outside of the flange body to fix it. The setting of the guide groove and the guide rod can prevent the fixing clamp from offsetting during movement, thereby further increasing the stability between the flange body and the fixed plate. The position of the fixing clamp can be adjusted by the bolt, clamping ring, and the clamping ring in conjunction with the arc plate and the threaded hole inside it, so that the fixing clamp can firmly fix the flange body, ensuring the accuracy of the docking between the flange body and the balancing valve body during the welding process.

A support block 13 is fixedly connected to the middle part of the upper end of the operating table 1, and a ball 14 is provided inside the support block 13. A balancing valve body 15 is provided at the upper end of the support block 13, and a flange body 18 is provided on one side of the fixed disk 12. A connecting rod 16 is fixedly connected to the upper end of the operating table 1 near the support block 13, and a welding gun 17 is provided on one side of the connecting rod 16. The slider 3 slides in the slide groove 2 in cooperation with the electric push rod 6 through the gear plate 4.

[0021] Specifically, the electric push rod 6 is turned on, and the electric push rod 6 pushes the gear plate 4 to move, thereby driving the gear 10 to rotate. While rotating, the gear 10 will drive the rotating shaft 8, the cylinder 11, and the fixed plate 12 to rotate, thereby realizing the change of the welding points between the flange body 18 and the balancing valve body 15. The welding gun 17 can perform annular welding around these welding points. During the rotation of the gear 10, the slider 3 will slide inside the slide groove 2. With the cooperation of the slider 3 and the slide groove 2, the stability of the flange body 18 and the balancing valve body 15 during rotation can be increased. The rotating shaft 8, the bearing 9, the gear 10, the cylinder 11 cooperates with the electric push rod 6 and the gear plate 4 to make the flange body 18 and the balancing valve body 15 rotate, and then the connection between the two components can be welded. Compared with traditional manual rotary welding, this welding method is more efficient.

[0022] Example 2

[0023] See also Figures 1-4 The utility model provides a technical solution: a balancing valve flange welding device, the outside of the fixed disk 12 is fixedly connected with an arc plate 19, one side of the arc plate 19 is provided with a guide groove 20, the inside of the guide groove 20 is movably connected with a guide rod 21, one end of the guide rod 21 is fixedly connected with a clamping ring 22, the right side of the clamping ring 22 is fixedly connected with a fixing clamp 24, the inside of the clamping ring 22 is movably connected with a clamping ring 23, and the left side of the clamping ring 23 is fixedly connected with a bolt 26, a threaded hole 25 is provided inside the arc plate 19, the fixing clamp 24 is movably connected to the bolt 26 through the clamping ring 22 and the clamping ring 23, the number of the arc plates 19 is multiple groups, and they are arranged at equal angles on the outside of the fixed disk 12.

[0024] Specifically, by rotating the bolt 26, under the action of the internal threaded hole 25 of the arc plate 19, the bolt 26 pushes the retaining ring 23 and the retaining ring 22 to one side, so that the fixing clamp 24 is tightly attached to the outside of the flange body 18 to fix it. The setting of the guide groove 20 and the guide rod 21 can prevent the fixing clamp 24 from offsetting during movement, thereby further increasing the stability between the flange body 18 and the fixed plate 12. The position of the fixing clamp 24 can be adjusted by the bolt 26, the retaining ring 23, and the retaining ring 22 in conjunction with the arc plate 19 and the threaded hole 25 inside it, so that the fixing clamp 24 can firmly fix the flange body 18, ensuring the accuracy of the docking between the flange body 18 and the balancing valve body 15 during the welding process.

[0025] Working principle: When the balancing valve flange welding device is in use, first, the two sets of flange bodies 18 to be welded are fixed on the fixing plate 12 respectively. The specific operation is to turn the bolt 26. Under the action of the internal threaded hole 25 of the arc plate 19, the bolt 26 pushes the clamping ring 23 and the clamping ring 22 to move to one side, thereby making the fixing clamp 24 close to the outside of the flange body 18 to fix it. The setting of the guide groove 20 and the guide rod 21 can prevent the fixing clamp 24 from deviating during movement, thereby further increasing the stability between the flange body 18 and the fixing plate 12. The position of the fixing clamp 24 can be adjusted by the bolt 26, the clamping ring 23, the clamping ring 22 in conjunction with the arc plate 19 and the threaded hole 25 inside it, thereby making the fixing clamp 24 able to firmly fix the flange body 18, ensuring the accuracy of the docking between the flange body 18 and the balancing valve body 15 during the welding process. After the flange body 18 is fixed, the balancing valve body 15 is placed on the support block 13, and the cylinder 1 is opened. 1, the cylinder 11 pushes the fixed plate 12 to move, thereby making the flange body 18 close to both sides of the balancing valve body 15, and the welding gun 17 is turned on. The welding gun 17 welds the connection between the two components. Finally, the electric push rod 6 is turned on, and the electric push rod 6 pushes the gear plate 4 to move, thereby driving the gear 10 to rotate. When the gear 10 rotates, it will drive the rotating shaft 8, the cylinder 11, and the fixed plate 12 to rotate, thereby changing the welding points of the flange body 18 and the balancing valve body 15. The welding gun 17 can perform annular welding around these welding points. During the rotation of the gear 10, the slider 3 will slide inside the slide groove 2. With the cooperation of the slider 3 and the slide groove 2, the stability of the flange body 18 and the balancing valve body 15 during rotation can be increased. The rotating shaft 8, bearing 9, gear 10, cylinder 11 cooperate with the electric push rod 6 and the gear plate 4 to rotate the flange body 18 and the balancing valve body 15, thereby welding the connection between the two components. Compared with traditional manual rotary welding, this welding method is more efficient.
