[0024] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] like Figure 1 As shown in Figure 6, the specific solution of the embodiment is as follows: A threaded pipe flange assembly device includes a pneumatic wrench 1, which serves as the power source for the entire assembly device and provides rotational power for the assembly of the flange 8 and the threaded pipe 9, so as to achieve fast and efficient assembly operation. Compared with traditional manual assembly, the high torque power provided by the pneumatic wrench 1 can significantly improve the assembly speed, reduce labor intensity, and improve the overall assembly efficiency. The output end of the air gun 1 is equipped with an adapter 2, which serves as a transition and adaptation to ensure that the power of the air gun 1 can be smoothly transmitted to the connecting seat 3 and subsequent components. The other end of the adapter 2 is equipped with a connecting seat 3. The end of the connecting seat 3 near the air gun 1 has a rectangular groove 31 that mates with the adapter 2. The connecting seat 3 is a key component connecting the air gun 1 and the mounting beam 5, transmitting the power of the air gun 1 to the mounting beam 5, thereby driving the fastening column 6 and the flange 8 to rotate. The design of the rectangular groove 31 can prevent the adapter 2 and the connecting seat 3 from slipping during the power transmission process.

[0027] A fastener 4 is provided between the connecting seat 3 and the adapter 2. The fastener 4 includes a fastening bolt 41 installed on the connecting seat. The fastening bolt 41 is used to firmly connect the adapter 2 and the connecting seat 3 together. By tightening the fastening bolt 41, it is ensured that the connecting seat 3 and the adapter 2 will not separate during assembly, thus ensuring the continuity of power transmission. An arc-shaped washer 42 is provided on the fastening bolt 41. The arc-shaped washer 42 is provided on the fastening bolt 41. When the fastening bolt 41 is tightened, the arc-shaped washer 42 can disperse the force. The tightening force ensures that the pressure is evenly distributed on the contact surfaces of the connecting seat 3 and the adapter 2. The adapter 2 is provided with a locking groove 43 that works in conjunction with the fastening bolt 41. The locking groove 43 is provided on the adapter 2 and works in conjunction with the fastening bolt 41. When the fastening bolt 41 is screwed into the locking groove 43, it can further restrict the relative movement between the adapter 2 and the connecting seat 3, enhance the connection's firmness, and prevent the adapter 2 and the connecting seat 3 from loosening or falling off when the air gun 1 rotates at high speed and generates a large torque, thus ensuring the safe operation of the device.

[0028] A mounting beam 5 is installed at the end of the connecting seat 3 away from the air jet 1. A rubber pad 51 is installed on the side of the mounting beam 5 away from the connecting seat 3. The rubber pad 51 has a thickness of 1cm-3cm and has a certain elasticity and cushioning effect, which can reduce the scratches on the surface of the flange 8 by the mounting beam 5, protect the anti-rust paint on the flange 8, and improve the quality and appearance integrity of the flange 8. At the same time, the rubber pad 51 can also play a certain role in shock absorption, reducing vibration and noise during assembly. The mounting beam 5 serves as the carrier for the mounting fastening column 6, providing stable support for the fastening column 6 and evenly distributing the power transmitted from the air jet 1 to the fastening column 6, thereby driving the flange 8 to rotate.

[0029] The mounting beam 5 is provided with a pair of fastening posts 6 for mounting the flange 8. Rubber rings 61 are respectively installed on the outer periphery of the pair of fastening posts 6. The rubber rings 61 increase the friction between the fastening posts 6 and the flange 8, preventing the flange 8 from sliding or falling off relative to the fastening posts 6 during the rotation of the flange 8 driven by the air gun 1, thereby improving the accuracy and stability of the assembly. The diameter of the fastening posts 6 is smaller than the height of the mounting beam 5. The diameter design of the fastening posts 6 provides sufficient space for the fastening posts 6 during installation and rotation, avoiding interference with the mounting beam 5. A pair of fastening posts 6 are in direct contact with the flange 8. By passing through the perforation of the flange 8, the power of the air gun 1 is transmitted to the flange 8, causing the flange 8 to rotate and achieve assembly with the threaded pipe 9.

[0030] An adjustment assembly 7 is provided between the pair of fastening posts 6 and the mounting beam 5. The adjustment assembly 7 includes a slide 71 opened on the mounting beam 5 and a connecting hole 72 opened on the inner wall of the slide 71. The slide 71 is provided with a movable seat 73 connected to the fastening post 6. The movable seat 73 is rectangular. A threaded post 74 is provided at the end of the movable seat 73 away from the fastening post 6. The threaded post 74 passes through the connecting hole 72. A fastening nut 75 is provided on the outer periphery of the threaded post 74. The slide rail 71 provides a track for the movable seat 73, allowing it to move freely within a certain range. The movement of the movable seat 73 adjusts the spacing between a pair of fastening posts 6 to accommodate the perforation spacing requirements of flanges 8 of different specifications, thus improving the versatility and adaptability of the device. The rectangular design of the movable seat 73 prevents the fastening posts 6 from rotating during operation. Simultaneously, the design of the movable seat 73 increases the connection strength between the fastening posts 6 and the mounting beam 5, preventing breakage at the connection point. By tightening the fastening nut 75, the threaded post 74 is fixed to the connecting hole 72, thereby locking the position of the movable seat 73 and ensuring that the fastening posts 6 do not move during assembly, guaranteeing assembly accuracy.

[0031] Example 2, as Figure 7 As shown, in some implementations, the adjusting component 7 can be replaced with other forms. The adjusting component 7 includes several threaded holes 76 formed on the surface of the mounting beam 5. Each pair of fastening posts 6 is provided with a threaded rod connected to the threaded hole 76. The threaded hole 76 provides an installation position for the threaded rod. Through the threaded hole 76 at different positions, multiple adjustment methods for the spacing of the fastening posts 6 can be realized, increasing the adjustment flexibility of the device and adapting to the assembly requirements of more flanges 8 of different specifications. This further improves the versatility and practicality of the device. The threaded rod is connected to the threaded hole 76. By screwing the threaded rod into the threaded hole 76 at different positions, the spacing between the fastening posts 6 can be adjusted. This adjustment method is simple to operate. The spacing adjustment can be completed simply by rotating the threaded rod. It is convenient and quick and can quickly meet the assembly requirements of flanges 8 of different specifications, thus improving production efficiency.

[0032] The operation steps of the above embodiment are as follows: When assembling flange 8 and threaded pipe 9, the construction personnel first screw flange 8 onto threaded pipe 9 one turn. An adapter 2 and a connecting seat 3 are assembled at the conveying end of the air gun 1 and locked by fastening bolts 41; Select a fastening post 6 that fits the perforation of flange 8 and assemble the fastening post 6 into slide rail 71; Adjust the spacing between a pair of fastening posts 6 according to the spacing of the perforations of flange 8. After adjustment, tighten the fastening nut 75. Pass a pair of fastening posts 6 through the holes in the flange 8, and start the air gun 1. The started air gun 1 drives the mounting beam 5 and the fastening posts 6 to rotate, thereby driving the flange 8 to screw the flange 8 into the threaded pipe 9.
