Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical processing technology, and in particular to a vertical water pipe welding positioning device. Background Technology
[0002] In the field of pipeline welding, especially in the welding of small-sized pipelines in process pipes and water supply systems in nuclear power plant construction, numerous technical challenges are faced. The complex construction site environment, with its intertwined pipelines and confined spaces, makes it difficult to effectively utilize traditional welding equipment.
[0003] Existing positioning devices generally suffer from a lack of diversity in structure and adaptability, failing to adjust flexibly according to pipe dimensions. This results in insufficient positioning accuracy, inconsistent welding quality, and low efficiency. Specifically, in current technologies, positioning devices are typically of fixed dimensions, making it difficult to adapt to pipes of different diameters and lengths. Frequent replacements or manual adjustments are required, increasing construction difficulty and time costs. Furthermore, inaccurate electrode positioning and poor thermal conductivity during welding lead to inconsistent weld quality and a low pass rate. Utility Model Content
[0004] The main purpose of this utility model is to provide a vertical water pipe welding positioning device, which aims to solve the problems of existing positioning devices having a simple structure, poor adaptability, and inability to be flexibly adjusted according to pipe size, resulting in insufficient positioning accuracy, unstable welding quality, and low efficiency.
[0005] To achieve the above-mentioned utility model objectives, the first aspect of this utility model proposes a vertical water pipe welding positioning device, including a base plate, an installation adjustment block, a guide post, a contour positioning fixture, a workpiece size positioning guide post, and a combination of pipe welding positioning copper electrodes. The guide post is mounted on the base plate via the mounting adjustment block, and the mounting adjustment block is configured to adjust the position of the guide post relative to the base plate; The contour positioning fixture is movably mounted on the guide post to accommodate workpieces of different sizes; The workpiece size positioning guide post includes a first positioning guide post and a second positioning guide post, which are fixed on the base plate; The tube welding positioning copper electrode assembly includes a first electrode and a second electrode, which are respectively set corresponding to the first positioning guide post and the second positioning guide post.
[0006] Furthermore, the base plate is provided with at least one pin hole for fixing the entire device with a pin.
[0007] Furthermore, the mounting adjustment block can be adjusted in position along the axial direction of the guide post to change the height of the guide post.
[0008] Furthermore, there are multiple guide posts arranged in parallel, and the contour positioning fixture is slidably mounted on the multiple guide posts.
[0009] Furthermore, the contour positioning fixture has a contoured surface that matches the shape of the water pipe to be welded, for precise positioning of the workpiece.
[0010] Furthermore, the first and second positioning guide posts are adjustablely mounted on the base plate to accommodate workpieces of different lengths.
[0011] Furthermore, the first electrode and the second electrode are respectively mounted on the first positioning guide post and the second positioning guide post.
[0012] Furthermore, the contour positioning fixture has a through threaded hole that is perpendicular to the axis of the guide post. The contour positioning fixture directly presses or abuts the surface of the guide post by screwing the end of the screw into the threaded hole, thereby locking its position on the guide post through friction.
[0013] Furthermore, the electrodes of the tube welding positioning copper electrode assembly are made of copper alloy material to provide good electrical and thermal conductivity during the welding process.
[0014] Furthermore, the surface of the contour positioning fixture that contacts the workpiece is coated with a high-temperature resistant, non-stick layer.
[0015] Beneficial effects: 1. This utility model's vertical water pipe welding positioning device, through the cooperative structure of the installation of adjusting blocks and guide columns, allows the height of the guide columns to be flexibly adjusted according to the height of the water pipe to be welded, adapting to workpieces of different heights. This significantly improves the device's versatility and applicability, reducing equipment replacement frequency. The workpiece size positioning guide columns include a first positioning guide column and a second positioning guide column, which are adjustablely mounted on the base plate. This allows the device to flexibly adjust the positioning spacing according to the workpiece length, precisely controlling the workpiece length positioning and greatly enhancing the device's adaptability. The contour positioning fixture has a contoured curved surface that matches the shape of the water pipe to be welded, allowing it to fit tightly against the workpiece and achieve precise workpiece positioning. This avoids welding misalignment and uneven weld seams caused by inaccurate positioning, improving welding quality.
[0016] 2. The vertical water pipe welding positioning device of this utility model ensures that the first electrode and the second electrode in the pipe welding positioning copper electrode assembly are respectively installed on the first positioning guide post and the second positioning guide post, so as to ensure that the electrode and the welding position are accurately aligned and avoid the problem of uneven welding quality caused by electrode position deviation.

[0025] In this embodiment, the guide post 3 and the mounting adjustment block 2 work together to precisely adjust the height and position of the guide post 3, thereby achieving adaptive positioning for workpieces of different heights. The movable design of the contour positioning fixture 4 allows the device to automatically adapt to water pipes of different sizes; The combination of the workpiece size positioning guide post 5 and the tube welding positioning copper electrode assembly 6 ensures the accuracy of workpiece length positioning and welding electrode position, thereby improving welding positioning accuracy and efficiency.
[0026] Optionally, the base plate 1 is provided with at least one pin hole 102 for fixing the entire device by a pin.
[0027] It should be noted that the design of the pin hole 102 allows the device to be firmly fixed on the workbench or the ground, effectively preventing the device from shifting during the welding process, ensuring the stability and safety of the welding process, and improving the welding quality.
[0028] Optionally, the mounting adjustment block 2 can be adjusted in position along the axial direction of the guide post 3 to change the height of the guide post 3.
[0029] It should be noted that the axially adjustable design of the mounting adjustment block 2 allows the height of the guide post 3 to be precisely adjusted according to the height of the workpiece, adapting to the welding requirements of water pipes of different heights, significantly improving the versatility and applicability of the device, and reducing the need to replace equipment.
[0030] Optionally, there are multiple guide posts 3 arranged in parallel, and the contour positioning fixture 4 is slidably mounted on the multiple guide posts 3.
[0031] It should be noted that the design of multiple parallel guide pillars 3 provides a more stable guiding system, effectively preventing the contour positioning fixture 4 from shifting or shaking during movement, and ensuring the accuracy of workpiece positioning. Multiple guide pillars work together to support the load, improving the stability and load-bearing capacity of the device, making it suitable for heavier workpieces.
[0032] Optionally, the contour positioning fixture 4 has a contoured surface that matches the shape of the water pipe to be welded, for precise positioning of the workpiece.
[0033] It should be noted that the contoured surface design can closely fit the shape of the water pipe to be welded, achieving precise positioning of the workpiece and avoiding quality problems such as welding misalignment and uneven weld due to inaccurate positioning.
[0034] Optionally, the first positioning guide post 51 and the second positioning guide post 52 are adjustablely mounted on the base plate 1 to accommodate workpieces of different lengths.

Next, adjust the positions of the first positioning guide post 51 and the second positioning guide post 52 on the base plate 1 according to the actual length of the water pipe, so that their spacing matches the length of the water pipe. Then, place the water pipe to be welded on the contour positioning fixture 4, and use the contour curved surface on the contour positioning fixture 4 that matches the shape of the water pipe to achieve the initial positioning of the workpiece. According to the specific dimensions of the water pipe, fine-tune the contour positioning fixture 4 on the guide post. Position the guide post 3 so that it is completely in contact with the water pipe. Then, use the threaded hole and screw on the contour positioning fixture 4 to lock the fixture position by using the friction generated by the screw end pressing the surface of the guide post 3. Install the first electrode 61 and the second electrode 62 on the first positioning guide post 51 and the second positioning guide post 52 respectively to ensure that the electrode and the welding position of the water pipe are precisely aligned. After checking that all components are firmly installed, start the welding equipment.
