Description

Technical Field

[0001] This utility model relates to the field of oil pipeline welding technology, and more specifically, to an oil pipeline welding positioning anti-deviation clamp. Background Technology

[0002] Welding is a crucial step in the construction and maintenance of oil pipelines. Welding quality directly affects the pipeline's sealing, durability, and safety, while precise positioning of the pipeline during welding is a vital prerequisite for ensuring weld quality.

[0003] In traditional welding processes, pipelines are usually positioned manually or using simple mechanical devices. However, these methods have many problems in actual operation, such as insufficient positioning accuracy and susceptibility to external environmental factors (such as wind and vibration) that can cause pipeline displacement, thereby affecting welding quality. With the expansion of the scale and the improvement of technical requirements of oil pipeline projects, traditional welding positioning methods are no longer able to meet the needs of modern construction. In particular, the problem of pipeline displacement is more prominent in the welding of long-distance, large-diameter pipelines, which not only increases the difficulty of welding but may also lead to welding defects and affect the overall performance of the pipeline.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a positioning and anti-displacement fixture for oil pipeline welding to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A positioning and anti-deviation fixture for oil pipeline welding includes a support frame, a first positioning component on one side of the support frame, and a second positioning component at one end of the first positioning component. The first positioning component includes a first motor, which is fixedly mounted on one side of the support frame. The output shaft of the first motor is connected to a worm gear via a coupling. The worm gear is meshed with a worm wheel, and a bidirectional screw is mounted on the worm wheel. Multiple adjustment slots are symmetrically opened at one end of the support frame. One end of the bidirectional screw extends into the interior of the adjustment slot and connects to the inner wall of one of the adjustment slots. Multiple adjustment seats are threaded onto the upper part of the bidirectional screw. The second positioning component includes a first positioning frame, which has an adjustment port. A third motor is fixedly mounted at the upper end of the first positioning frame.

[0008] Furthermore, in order to better ensure the guiding effect, a first guide rod is symmetrically slidably connected to the upper part of the adjusting seat, and the two ends of the first guide rod are connected to the inner wall of the adjusting groove. A movable groove is opened at one end of the adjusting seat.

[0009] Furthermore, to better ensure the adjustment effect of the Y-axis, a movable plate is slidably connected inside the movable slot, and the movable plate is adapted to the movable slot. A moving slot is symmetrically opened on one side of the support frame, and a mounting seat is slidably connected inside the moving slot, and the mounting seat is adapted to the moving slot.

[0010] Furthermore, to better ensure the adjustment effect, a second motor is fixedly installed on one side of the mounting base, and an adjusting gear is fixedly installed on the output shaft of the second motor. A rack is meshed on the adjusting gear, and the rack is fixedly installed on one side of the movable plate.

[0011] Furthermore, to better ensure the adjustment effect of the Z-axis, the first positioning frame is fixedly set at the upper end of the movable plate, and the output shaft of the third motor is provided with a threaded rod through the coupling. One end of the threaded rod passes through the movable plate and is connected to one end of the movable plate. A second positioning frame is threadedly connected to the threaded rod, and a second guide rod is connected to the second positioning frame.

[0012] Furthermore, to better ensure the welding effect of the pipeline, the two ends of the second guide rod are respectively connected to the first positioning frame and one end of the movable plate. One side of the movable plate is symmetrically equipped with electric push rods through the mounting plate. One end of the electric push rod is equipped with a mounting frame. One side of the mounting frame is equipped with a fourth motor. The output shaft of the fourth motor is connected to a rotating rod through a coupling. One end of the rotating rod extends to the inner wall of the mounting frame and is connected with a guide wheel.

[0013] Furthermore, a controller and a battery are installed on one side of the support frame.

[0014] The beneficial effects of this utility model are as follows: By cooperating with the first positioning component and the second positioning component, multiple directions of adjustment along the X, Y, and Z axes can be achieved, effectively solving the problem of insufficient positioning accuracy in traditional welding positioning methods. Through this multi-axis adjustment function, the fixture can precisely adjust the position of the pipeline, ensuring the alignment and positioning accuracy of the pipeline during welding, thereby improving welding quality. This multi-axis adjustment function allows the fixture to flexibly adapt to pipelines of different sizes and positions, maintaining high-precision positioning even in complex construction environments, reducing welding defects caused by pipeline offset, improving welding efficiency and quality, and ensuring the sealing, durability, and safety of oil pipelines. In addition, the automated adjustment function of this fixture reduces manual intervention and lowers construction difficulty, making it particularly suitable for welding construction of long-distance, large-diameter pipelines.

[0033] X-axis adjustment

[0034] The first motor 201 drives the worm gear 202 to rotate. Through the cooperation of the worm wheel 203 and the double screw 204, the adjusting seat 205 moves along the double screw 204. Under the guidance of the first guide rod 206, the adjusting seat 205 remains stable and drives the movable plate 207 to move along the X-axis, thus completing the precise positioning of the pipeline in the horizontal direction.

[0035] Y-axis adjustment

[0037] Z-axis adjustment

[0038] The third motor 302 drives the threaded rod 303 to rotate, which in turn moves the second positioning frame 304 along the Z-axis. The second guide rod 305 ensures that the movement direction of the second positioning frame 304 is accurate, thus completing the precise positioning of the pipe in the vertical height. At the same time, the electric push rod 306 pushes the mounting frame 307 to slide along the movable plate 207. The fourth motor 308 drives the rotating rod 309 to rotate, and the guide wheel 310 on the rotating rod 309 rotates accordingly, clamping the pipe and keeping it stable.

[0039] During the welding process, the guide wheel 310 rotates continuously to ensure that the pipe rotates evenly during welding, while preventing deviation caused by vibration or external force. The controller 5 monitors the position and status of the pipe in real time and adjusts the operating parameters of each motor as needed to ensure the stability and accuracy of the welding process.
