Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] like Figures 1-4 As shown: This embodiment provides a positioning device for flange welding. The device has two components, and their height can be adjusted by independently controlled telescopic push rods. These telescopic push rods are hydraulic push rods. The extension and retraction of the output rod of the telescopic push rod can move the positioning device above it along the axis of the telescopic push rod for lifting and lowering operations. The device includes a movable platform 100 mounted on a welding table. A mounting frame 200, which is U-shaped, is mounted on the movable platform 100 and can slide along the movable platform 100. An adjustment component 300 is mounted on the mounting frame 200, and a positioning chuck 400 is mounted on the adjustment component 300. The adjustment component 300 can adjust the tilt angle of the positioning chuck 400. This invention allows for convenient and quick adjustment of the tilt angle of the positioning chuck 400 through the adjustment component 300, making it suitable for welding needs under various working conditions. It has greater applicability, greatly improves welding efficiency, and makes operation more convenient.

[0024] According to one embodiment of the present invention, such as Figures 1-4As shown, the mobile platform 100 includes a first motor 101 disposed at the lower part of the mounting bracket 200. The first motor 101 is a servo motor. A first rotating shaft 102 is disposed at the end of the output shaft of the first motor 101. A first bevel gear 103 is disposed on the first rotating shaft 102. There are two first bevel gears 103, which are symmetrically disposed on both sides of the first rotating shaft 102. A second bevel gear 104 is meshed on each first bevel gear 103. A connecting shaft 105 is disposed between the axes of the two second bevel gears 104 on the same vertical line. A first gear 106 is disposed on the outer side of the connecting shaft 105. There are two first gears 106, which are disposed on both sides of the connecting shaft 105. A rack 107 is also welded onto the welding table. A gear 106 can slide along a rack 107. This invention can rotate a first bevel gear 103 by rotating the output shaft of a first motor 101. The rotation of the first bevel gear 103 can rotate a second bevel gear 104 that meshes with it. The rotation of the second bevel gear 104 can rotate a connecting shaft 105 and the first gear 106 below it. In addition, the meshing action between the rack 107 and the first gear 106, as well as the fixing action of the welding table on the rack 107, allow the mounting bracket 200 to slide along the rack 107 while the first gear 106 rotates.

The positioning chuck 400 is fixedly mounted to the half-gear 303. A driven gear 304 is fixedly mounted on the second rotating shaft 301. A servo motor 305 is mounted on the mounting frame 200. An active gear 306 meshes with the driven gear 304 at the end of the output shaft of the servo motor 305. This invention allows the active gear 306 to rotate via the rotation of the output shaft of the servo motor 305. The rotation of the active gear 306 causes the driven gear 304 to rotate as well. The rotation of the driven gear 304 causes the second rotating shaft 301 and the half-gear 303 to rotate the positioning chuck 400 by a corresponding angle, thereby enabling convenient and quick adjustment of the tilt angle of the positioning chuck 400, making operation more convenient.

[0026] According to another embodiment of the present invention, such as Figure 1 and Figure 2As shown, a mounting plate 500 is provided on the axis of the half gear 303, and a third rotating shaft 501 is rotatably provided on the axis of the mounting plate 500. A third gear 502 is provided on the third rotating shaft 501, and a second motor 503 is also provided on the mounting plate 500. A drive gear 504 that meshes with the third gear 502 is provided at the end of the output shaft of the second motor 503. In this invention, the rotation of the output shaft of the second motor 503 can drive the drive gear 504 to rotate together. The rotation of the drive gear 504 can drive the third gear 502 and the rotating shaft to rotate together. The rotation of the third gear 502 can drive the positioning chuck 400 to rotate along the axial direction, thereby realizing the circumferential welding operation of the flange to be welded.

[0027] According to another embodiment of the present invention, such as Figure 1 and Figure 4 As shown, the positioning chuck 400 is a hydraulic chuck. The hydraulic chuck and the hydraulic station are connected by a rubber oil pipe. Rotary oil pipe joints are provided between the rubber oil pipe and the hydraulic chuck and the hydraulic station. Multiple sliding grooves 401 are evenly distributed on the positioning chuck 400. A chuck 402 is slidably arranged in each sliding groove 401.

[0028] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, each slide groove 401 is also equipped with a scale 403, which is engraved with a number. This utility model can quickly and efficiently read the diameter of the clamping part of the flange to be clamped through the scale 403, making it easier for users to grasp the diameter of the flange to be clamped quickly and easily.

When welding flanges and pipes is required, especially when the flanges and pipes need to be tilted before welding, the operator places the flanges and pipe fittings to be welded on the positioning chuck 400, starts the positioning chuck 400 to clamp and fix them, and then starts the output rods of the corresponding telescopic push rods to extend or retract to the appropriate height. Then, the output shaft of the servo motor 305 is started to rotate to the corresponding angle, and then the moving platform 100 is started to align the flanges and pipes to be welded. Then, the welding machine can be started to perform the welding operation. This utility model can conveniently and quickly adjust the tilt angle of the positioning chuck 400 through the adjustment component 300, which is suitable for welding needs under various working conditions, has stronger applicability, greatly improves welding efficiency, and makes operation more convenient.
