Description

Technical Field

[0001] This utility model mainly relates to the field of flange production, and specifically to an automatic flange welding device. Background Technology

[0002] Flange connections are an indispensable method for connecting pipes, valves, and equipment in fields such as petrochemicals, power energy, shipbuilding, pressure vessels, and pipeline engineering. The sealing performance and strength of these connections directly affect the safe, reliable operation, and long service life of the entire system.

[0003] Welding is one of the most important processes for connecting flanges to pipes / equipment. Welding quality (such as the tightness, uniformity, and defect-free nature of the weld) is a key factor in ensuring the performance of flange connections.

[0004] During the operation of specific embodiments, the inventors discovered the following defects:

[0005] However, during the welding process between the flange and the pipeline, the hole in the middle of the flange is aligned with the pipeline. When the two are misaligned, it will cause the welding device to make a deviation in the welding between the flange and the pipeline, resulting in a larger gap between the two and affecting the stability after welding.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0033] The pipe fixing structure 3 includes a second lifting plate 301. A second mating hole 302 is formed in the center of the second lifting plate 301. Sliding holes 303 are formed on both sides inside the second lifting plate 301. A positioning rod 304 is rotatably connected to the outer wall of the second lifting plate 301. One end of the positioning rod 304 is rotatably connected to a limiting strip 305. An auxiliary block 306 is provided at the bottom of the limiting strip 305. Multiple limiting strips 305 are arranged in a circular array on the outer wall of the second lifting plate 301. The auxiliary block 306 at the bottom of the limiting strip 305... 6 is slidably connected to the second guide groove 107, and then the pipe is placed on the top of the flange. The second transmission screw 108 is manually rotated, and the second transmission screw 108 drives the second lifting plate 301 to rise and fall. The second lifting plate 301 drives the sliding hole 303 to slide on the outer wall of the sliding rod 109. During the rising and falling process of the second lifting plate 301, it pushes the positioning rod 304 to rotate. The positioning rod 304 pushes the auxiliary block 306 at the bottom of the limiting strip 305 to slide on the inner wall of the second guide groove 107. Then the limiting strip 305 moves outward to push the pipe to move, so that the pipe is aligned with the flange to facilitate welding by the welder 111.

[0034] Furthermore, the support structure 1 includes a base plate 101 with a drive gear 102 rotatably connected to one side; a rotating gear ring 103 rotatably connected to the outer wall of the base plate 101, the rotating gear ring 103 meshing with the drive gear 102; a first guide groove 104 formed inside the base plate 101; an auxiliary frame 110 rotatably connected to the top of the rotating gear ring 103; a welder 111 provided at one end of the auxiliary frame 110; a first transmission screw 105 rotatably connected to the bottom of the base plate 101; a support frame 106 provided at the top of the base plate 101; a second transmission screw 108 rotatably connected to the top of the support frame 106; and a... Slide rods 109 are provided on both sides. The support frame 106 has a second guide groove 107 inside. When welding is required between the flange and the pipe, the flange is placed on top of the flange fixing structure 2, the pipe is placed on top of the flange, and the position of the pipe is adjusted by the pipe fixing structure 3. Then, a motor is provided on one side of the base plate 101. The output end of the motor is connected to the drive gear 102. The motor is started, and the motor drives the drive gear 102 to rotate. The drive gear 102 drives the rotating gear ring 103 to rotate. The rotating gear ring 103 drives the auxiliary frame 110 to move. The welding device 111 is aligned with the connection position between the pipe and the flange. The welding device 111 is started to weld the two together.

[0035] Furthermore, the flange fixing structure 2 includes a first mating hole 202 in the middle of a first lifting plate 201, which mates with a first transmission screw 105. A first rotating frame 203 is rotatably connected to the outer wall of the first lifting plate 201. A push rod 204 is rotatably connected to one end of the first rotating frame 203. A slider 205 is provided at the top of the push rod 204, and a shaft 206 is provided at the bottom of the push rod 204. The slider 205 is slidably connected to a first guide groove 104.
